The presence of proteins in the urine, an indicator of KIDNEY DISEASES.
A cluster of convoluted capillaries beginning at each nephric tubule in the kidney and held together by connective tissue.
A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.
Highly differentiated epithelial cells of the visceral layer of BOWMAN CAPSULE of the KIDNEY. They are composed of a cell body with major CELL SURFACE EXTENSIONS and secondary fingerlike extensions called pedicels. They enwrap the KIDNEY GLOMERULUS capillaries with their cell surface extensions forming a filtration structure. The pedicels of neighboring podocytes interdigitate with each other leaving between them filtration slits that are bridged by an extracellular structure impermeable to large macromolecules called the slit diaphragm, and provide the last barrier to protein loss in the KIDNEY.

Chronic glomerulonephritis characterized histologically by proliferation of MESANGIAL CELLS, increase in the MESANGIAL EXTRACELLULAR MATRIX, and a thickening of the glomerular capillary walls. This may appear as a primary disorder or secondary to other diseases including infections and autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Various subtypes are classified by their abnormal ultrastructures and immune deposits. Hypocomplementemia is a characteristic feature of all types of MPGN.

Inflammation of the interstitial tissue of the kidney. This term is generally used for primary inflammation of KIDNEY TUBULES and/or surrounding interstitium. For primary inflammation of glomerular interstitium, see GLOMERULONEPHRITIS. Infiltration of the inflammatory cells into the interstitial compartment results in EDEMA, increased spaces between the tubules, and tubular renal dysfunction.

It blocks de novo biosynthesis of purine nucleotides by inhibition of the enzyme inosine monophosphate dehydrogenase. Mycophenolic acid is important because of its selective effects on the immune system. It prevents the proliferation of T-cells, lymphocytes, and the formation of antibodies from B-cells. It also may inhibit recruitment of leukocytes to inflammatory sites. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p1301)

Clinical symptoms include URTICARIA; ERYTHEMA; ARTHRITIS; GASTROINTESTINAL HEMORRHAGE; and renal involvement. Most cases are seen in children after acute upper respiratory infections.
A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.

Angiotensin-converting enzyme is upregulated in the proximal tubules of rats with intense proteinuria. (1/3373)

Persistent proteinuria is considered a deleterious prognostic factor in most progressive renal diseases. However, the mechanisms by which proteinuria induces renal damage remain undetermined. Since proximal tubular cells possess all the machinery to generate angiotensin II (Ang II), we approached the hypothesis that proteinuria could elicit the renal activation of the renin-angiotensin system in a model of intense proteinuria and interstitial nephritis induced by protein overload. After uninephrectomy (UNX), Wistar-Kyoto rats received daily injections of 1 g BSA or saline for 8 days. The mean peak of proteinuria was observed at the fourth day (538+/-89 versus 3+/-1 mg/24 h in UNX controls; n=12; P<0.05) and was increased during the whole study period (at the eighth day: 438+/-49 mg/24 h; n=12; P=NS). Morphological examination of the kidneys at the end of the study showed marked tubular lesions (atrophy, vacuolization, dilation, and casts), interstitial infiltration of mononuclear cells, and mesangial expansion. In relation to UNX control rats, renal cortex of BSA-overloaded rats showed an increment in the gene expression of angiotensinogen (2.4-fold) and angiotensin-converting enzyme (ACE) (2.1-fold), as well as a diminution in renin gene expression. No changes were observed in angiotensin type 1 (AT1) receptor mRNA expression in both groups of rats. By in situ reverse transcription-polymerase chain reaction and immunohistochemistry, ACE expression (gene and protein) was mainly localized in proximal and distal tubules and in the glomeruli. By immunohistochemistry, angiotensinogen was localized only in proximal tubules, and AT1 receptor was localized mainly in proximal and distal tubules. In the tubular brush border, an increase in ACE activity was also seen (5. 5+/-0.5 versus 3.1+/-0.7 U/mg protein x10(-4) in UNX control; n=7; P<0.05). Our results show that in the kidney of rats with intense proteinuria, ACE and angiotensinogen were upregulated, while gene expression of renin was inhibited and AT1 was unmodified. On the whole, these data suggest an increase in Ang II intrarenal generation. Since Ang II can elicit renal cell growth and matrix production through the activation of AT1 receptor, this peptide may be responsible for the tubulointerstitial lesions occurring in this model. These results suggest a novel mechanism by which proteinuria may participate in the progression of renal diseases.  (+info)

Up-regulation of glomerular extracellular matrix and transforming growth factor-beta expression in RF/J mice. (2/3373)

BACKGROUND: RF/J mice were first reported as a murine model of spontaneous glomerulosclerosis by Gude and Lupton in 1960, but the precise histologic characteristics and immunopathological background of this mouse have not been investigated further. METHODS: Measurements of serum levels of immunoglobulins, anti-single strand DNA (anti-ss-DNA) antibody, complement (C3), and circulating immune complex (IC) were performed. Analyses of glomerular histological and immunopathological lesions in association with the detection of mRNA expression of collagen IV, TGF-beta, matrix protein turnover related enzymes, matrix metalloproteinase-2 (MMP-2), tissue inhibitor of metalloproteinase-2 (TIMP-2) and platelet-derived growth factor (PDGF) were also performed in young (10-week-old) and elderly (60-week-old) RF/J mice with age-matched BALB/C mice as the controls. RESULTS: High levels of serum IgA and IgG from as early as 20 weeks of age were noted in the RF/J mice. Serum anti-ss-DNA antibody of aged RF/J mice increased up to 23% of that of aged MRL-lpr/lpr mice, and serum C3 concentration significantly decreased with age, reaching lower levels than that of BALB/c mice. IgA-IC levels were significantly high compared to BALB/C mice both in the early and late stages of life, whereas IgG-IC levels were high only in mice younger than 20 weeks. Semiquantitative and quantitative analyzes of renal histopathological findings revealed significantly marked and age-related mesangial matrix expansion in RF/J mice, with increasing frequency of global glomerular sclerosis and tubulointerstitial damage. On the other hand, although precise measurements of glomerular cell numbers also showed an apparent augmentation in both young and old RF/J mice compared to BALB/C mice, glomerular cellularity decreased with age in RF/J mice. Immunohistochemical study revealed massive immunoglobulin deposition from a young age in association with significantly higher accumulation of matrix proteins, such as types I and IV collagen and laminin from the early stage of life. In addition, in these glomeruli, transforming growth factor-beta1 (TGF-beta1) was highly expressed both in young and old mice. The mRNA expression of MMP-2 was up-regulated only in the early stage of life. Although PDGF mRNA of RF/J mice was significantly up-regulated in the early stage of life, the differences between the mice disappeared in the late stage of life. CONCLUSIONS: These findings suggest that in RF/J mice, an immunopathological background inducing high serum immunoglobulin and IC levels from the early stage of life is closely related to mesangioproliferative glomerular lesions mediated by PDGF, and that development of massive extracellular matrix accumulation in glomeruli was induced by up-regulated expression of TGF-beta with inappropriate regulation of protein turnover-related enzyme production.  (+info)

Blocking angiotensin II ameliorates proteinuria and glomerular lesions in progressive mesangioproliferative glomerulonephritis. (3/3373)

BACKGROUND: The renin-angiotensin system is thought to be involved in the progression of glomerulonephritis (GN) into end-stage renal failure (ESRF) because of the observed renoprotective effects of angiotensin-converting enzyme inhibitors (ACEIs). However, ACEIs have pharmacological effects other than ACE inhibition that may help lower blood pressure and preserve glomerular structure. We previously reported a new animal model of progressive glomerulosclerosis induced by a single intravenous injection of an anti-Thy-1 monoclonal antibody, MoAb 1-22-3, in uninephrectomized rats. Using this new model of progressive GN, we examined the hypothesis that ACEIs prevent the progression to ESRF by modulating the effects of angiotensin II (Ang II) on the production of transforming growth factor-beta (TGF-beta) and extracellular matrix components. METHODS: We studied the effect of an ACEI (cilazapril) and an Ang II type 1 receptor antagonist (candesartan) on the clinical features and morphological lesions in the rat model previously reported. After 10 weeks of treatment with equihypotensive doses of cilazapril, cilazapril plus Hoe 140 (a bradykinin receptor B2 antagonist), candesartan, and hydralazine, we examined systolic blood pressure, urinary protein excretion, creatinine clearance, the glomerulosclerosis index, and the tubulointerstitial lesion index. We performed a semiquantitative evaluation of glomerular immunostaining for TGF-beta and collagen types I and III by immunofluorescence study and of these cortical mRNA levels by Northern blot analysis. RESULTS: Untreated rats developed massive proteinuria, renal dysfunction, and severe glomerular and tubulointerstitial injury, whereas uninephrectomized control rats did not. There was a significant increase in the levels of glomerular protein and cortical mRNA for TGF-beta and collagen types I and III in untreated rats. Cilazapril and candesartan prevented massive proteinuria, increased creatinine clearance, and ameliorated glomerular and tubulointerstitial injury. These drugs also reduced levels of glomerular protein and cortical mRNA for TGF-beta and collagen types I and III. Hoe 140 failed to blunt the renoprotective effect of cilazapril. Hydralazine did not exhibit a renoprotective effect. CONCLUSION: These results indicate that ACEIs prevent the progression to ESRF by modulating the effects of Ang II via Ang II type 1 receptor on the production of TGF-beta and collagen types I and III, as well as on intrarenal hemodynamics, but not by either increasing bradykinin activity or reducing blood pressure in this rat model of mesangial proliferative GN.  (+info)

Proteinuria induces tubular cell turnover: A potential mechanism for tubular atrophy. (4/3373)

BACKGROUND: Proteinuria and tubular atrophy have both been closely linked with progressive renal failure. We hypothesized that apoptosis may be induced by tubular cell exposure to heavy proteinuria, potentially leading to tubular atrophy. Apoptosis was studied in a rat model of "pure" proteinuria, which does not induce renal impairment, namely protein-overload proteinuria. METHODS: Adult female Lewis rats underwent intraperitoneal injection of 2 g of bovine serum albumin (BSA, N = 16) or sham saline injections (controls, N = 8) daily for seven days. Apoptosis was assessed at day 7 in tissue sections using in situ end labeling (ISEL) and electron microscopy. ISEL-positive nuclei (apoptotic particles) were counted in blinded fashion using image analysis with NIH Image. Cell proliferation was assessed by detection of mRNA for histone by in situ hybridization, followed by counting of positive cells using NIH Image. RESULTS: Animals injected with saline showed very low levels of apoptosis on image analysis. BSA-injected rats had heavy proteinuria and showed both cortical and medullary apoptosis on ISEL. This was predominantly seen in the tubules and, to a lesser extent, in the interstitial compartment. Overall, the animals injected with BSA showed a significant 30-fold increase in the number of cortical apoptotic particles. Electron microscopy of tubular cells in a BSA-injected animal showed a progression of ultrastructural changes consistent with tubular cell apoptosis. The BSA-injected animals also displayed a significant increase in proximal tubular cell proliferation. This increased proliferation was less marked than the degree of apoptosis. CONCLUSION: Protein-overload proteinuria in rats induces tubular cell apoptosis. This effect is only partially balanced by proliferation and potentially provides a direct mechanism whereby heavy proteinuria can induce tubular atrophy and progressive renal failure.  (+info)

Mycophenolate mofetil prevents the progressive renal failure induced by 5/6 renal ablation in rats. (5/3373)

BACKGROUND: Extensive renal ablation is associated with progressive sclerosis of the remnant kidney. Because lymphocytes and monocytes accumulate in the remnant kidney, it is likely that they play a role in the renal scarring. Therefore, we treated rats with 5/6 nephrectomy (5/6Nx) with mycophenolate mofetil (MMF), a drug that has an antiproliferative effect and that suppresses the expression of intercellular adhesion molecules. METHODS: Sprague-Dawley rats with 5/6Nx received MMF (30 mg. kg-1. day-1 by daily gastric gavage, N = 15) or vehicle (N = 16). Ten additional rats were sham operated. All rats were fed a 30% protein diet. Body weight, serum creatinine, and urinary protein excretion were determined weekly. Lipid peroxidation, as a measure of oxidative stress observed by urinary malondialdehyde determinations, was performed every two weeks. Histologic studies were done in the remnant kidney four weeks (9 rats from the vehicle-treated group, 7 rats from the MMF group, and 5 sham-operated rats) and eight weeks after surgery (the remaining rats). Glomerular volume, sclerosis in glomeruli (segmental and global) and interstitium (semiquantitative scale), infiltrating lymphocytes and macrophages (CD43- and ED1-positive cells), and expression of adhesion molecules (CD54, CD18, and CD11b) were analyzed. RESULTS: MMF treatment prevented the progressive increment in serum creatinine and the proteinuria observed in the 5/6 nephrectomized rats during the eight weeks of observation (P < 0.01). Weight gain was comparable in the MMF-treated and sham-operated rats, whereas weight gain was decreased in untreated 5/6 nephrectomized rats. Excretion of malondialdehyde increased after surgery but returned sooner to control levels in the MMF-treated rats. Increments in glomerular size and mean arterial blood pressure induced by renal ablation were not modified by MMF treatment. Eight weeks after surgery, segmental sclerosis was present in 48.4 +/- 8.35% (+/- sd) glomeruli in the vehicle-treated group versus 25 +/- 10.5% in the MMF-treated group (P < 0.001). Interstitial fibrosis was reduced significantly with MMF treatment (P < 0.001). Infiltration with CD43- and ED1-positive cells in glomeruli and interstitium was two to five times lower in MMF-treated rats (P < 0.01). Expression of adhesion molecules CD18 and CD11b was similarly reduced. CONCLUSION: MMF ameliorates the progressive renal damage in the remnant kidney after 5/6Nx. This effect is associated with a reduction in the infiltration of lymphocytes and monocytes, whereas glomerular hypertrophy and systemic hypertension are unchanged.  (+info)

HIV-associated nephropathy is a late, not early, manifestation of HIV-1 infection. (6/3373)

BACKGROUND: Human immunodeficiency virus-associated nephropathy (HIVAN) can be the initial presentation of HIV-1 infection. As a result, many have assumed that HIVAN can occur at any point in the infection. This issue has important implications for appropriate therapy and, perhaps, for pathogenesis. Since the development of new case definitions for acquired immunodeficiency syndrome (AIDS) and better tools to assess infection, the relationship of HIVAN to the time of AIDS infection has not been addressed. In this study, we reassessed the stage of infection at the time of HIVAN diagnosis in 10 patients, and we reviewed all previously published cases applying the new case definitions to assess stage of infection. METHODS: HIVAN was confirmed by kidney biopsy in HIV seropositive patients with azotemia and/or proteinuria. CD4+ cell count and plasma HIV-1 RNA copy number were measured. We also reviewed all published cases of HIVAN to determine if AIDS-defining conditions, by current Centers for Disease Control definitions, were present in patients with biopsy-proven HIVAN. RESULTS: Twenty HIV-1 seropositive patients with proteinuria and an elevated creatinine concentration were biopsied. HIVAN was the single most common cause of renal disease. CD4+ cell count was below 200/mm3 in all patients with HIVAN, fulfilling Centers for Disease Control criteria for an AIDS-defining condition. HIV-1 plasma RNA was detectable in all patients with HIVAN. In reviewing previous reports, an AIDS-defining condition was present in virtually all patients with HIVAN. CONCLUSION: HIVAN develops late, not early, in the course of HIV-1 infection following the development of AIDS. This likely accounts for the poor prognosis noted in previous publications and has implications for pathogenesis. In addition, given the detectable viral RNA levels, highly active antiretroviral therapy is indicated in HIVAN. Highly active antiretroviral therapy may improve survival as well as alter the natural history of HIVAN.  (+info)

Long-term effects of cyclosporine A in Alport's syndrome. (7/3373)

BACKGROUND: In 1991, our initial results of cyclosporine A (CsA) administration in eight patients with Alport's syndrome were published. A significant decrease in or disappearance of proteinuria and apparently good tolerance to CsA were observed in all patients. METHODS: CsA administration has been maintained in these eight patients with the aim of obtaining further information about the clinical course of the disease. The ages of these eight patients currently range from 15 to 27 years, and the mean duration of treatment is from 7 to 10 years (x = 8.4 years). RESULTS: Renal function has remained stable, with no evaluable changes in serum creatinine levels compared with pre-CsA treatment values. Proteinuria in all patients has either remained negative or are values far lower than pretreatment levels. A second renal biopsy was performed in all patients after five years of CsA administration. No aggravation of the lesion present at the first biopsy or lesions typical of cyclosporine intoxication was observed. CONCLUSIONS: After a mean duration of 8.4 years and with no deterioration in renal function, we found possible beneficial effects of the continued treatment of CsA in patients with Alport's syndrome who present evidence of progression to renal insufficiency.  (+info)

Circulating vascular endothelial growth factor is not increased during relapses of steroid-sensitive nephrotic syndrome. (8/3373)

BACKGROUND: An uncharacterized circulating factor that increases vascular permeability has previously been described in childhood steroid-sensitive nephrotic syndrome (SSNS). The aim of this study was to determine whether this factor is vascular endothelial growth factor (VEGF), the recently described endothelial cell mitogen and enhancer of vascular permeability. METHODS: Plasma and urine VEGF levels were measured in children with SSNS in both relapse and remission and in normal age- and sex-matched controls. Semiquantitative reverse transcriptase-polymerase chain reaction studies investigating VEGF mRNA expression were performed on peripheral blood mononuclear cells isolated from children with SSNS in relapse and controls. In two experimental models (one-hour and three-day follow-up postinfusion), Sprague-Dawley rats were intravenously administered 50 microg rVEGF to determine whether this induced either proteinuria or glomerular histologic change. RESULTS: Plasma VEGF levels and urine VEGF/creatinine ratios were not elevated in SSNS relapse compared with remission and control samples. Peripheral blood mononuclear cell VEGF mRNA expression was no different in SSNS patients compared with controls. The administration of VEGF to rats induced an acute reversible fall in systemic blood pressure but did not result in the development of either proteinuria or glomerular histologic change. CONCLUSION: Increased circulating VEGF levels are not responsible for the proteinuria observed during relapses of SSNS. Further studies are warranted to investigate intrarenal VEGF expression.  (+info)

It has been considered unlikely that patients with insulin-dependent diabetes and diabetic nephropathy with nephrotic range proteinuria can substantially reduce proteinuria and continue for many years without further loss of renal function. We present a patient who had the diagnosis of insulin-dependent diabetes made at age 15, had his first of 6 laser treatments for proliferative and hemorrhagic retinopathy at age 27 and was found to have nephrotic range proteinuria and edema with hypertension at age 29, when results of a renal biopsy were typical of diabetic nephropathy. Ten years later, with the last 5.5 years on ACE inhibitors, proteinuria has been | 0.65 g/24 h for 2 years and recently 0.22 g, serum creatinine is unchanged at 90 to 102 μmol/l, DTPA GFR is 104 ml/min and retinopathy has remained stable without laser therapy for 7 years. Blood pressure on clinic visits has averaged 126/74 for the last 8 years. This duration of stable renal function and the major decrease in proteinuria after being
Ability and willingness to provide informed consent (adults greater than or equal to 18 years) or assent (children greater than or equal to 13 years) to all aspects of the study after full information is provided.. Nephrotic range proteinuria that persists for at least 3 months.. Nephrotic range proteinuria that persists despite angiotensin antagonist therapy (ACE inhibitor or ARB) for at least on month, unless intolerant. If patients have not started ACE inhibitor therapy before they are referred to NIH, we plan to start lisinopril 5 mg daily. We will advance the dose of ACE inhibitor as tolerated. Nephrotic range proteinuria, defined as 24 hour urine protein excretion greater than or equal to 3.5 g/d, must be documented in at least two 24 hour urine collections obtained during the month prior to initiating sirolimus. Incomplete urine collections (based on inadequate creatinine excretion) will be excluded.. Renal biopsy must reveal typical changes of membranous nephropathy by light and electron ...
Clinical Journal of the American Society of Nephrology. 2015. 10(4):571-577.. In children with nonglomerular chronic kidney disease (CKD), baseline proteinuria and systolic blood pressure levels are independently associated with progression of CKD. That was the conclusion of a study conducted recently by Sahar A. Fathallah-Shaykh, MD, and colleagues.. Most cases of CKD in children are causes by congenital anomalies of the kidney and urinary tract or genetic disorders. The researchers in this study aimed to evaluate the relationships between baseline proteinuria and blood pressure and longitudinal changes in glomerular filtration rate (GFR) in children with nonglomerular causes of CKD.. The prospective CKD in Children study assessed the urine protein-to-creatinine ratio, casual systolic and diastolic blood pressure (normalized for age, sex, and height), and GFR decline in 522 children with nonglomerular CKD. Median age was 10 years and median follow-up was 4.4 years. Mean baseline eGFR of 52 ...
The presence of proteinuria (,300 mg/d) represents an important factor in the diagnosis and evaluation of the pregnant patient with an hypertensive disorder. The 24 hour collection of urine for proteinuria is the gold standard for the diagnosis of the condition and allows the physician to determine if an hypertensive disorder is related directly or not to the gestation.. The problem is the time it takes and the technical difficulties related to the sample collection. An alternative is the quantification of protein and creatinine in a random sample of urine. We seek to evaluate if this method is as affective as the gold standard in the diagnosis of proteinuria (,300 mg/d). ...
In the RENAAL study, the prespecified analysis accounted for the impact of baseline proteinuria as a covariate by including the proteinuria strata used at randomization. Subsequent analyses of the unblinded RENAAL study database revealed that baseline proteinuria levels were unbalanced in the upper stratum. Adjustment for baseline proteinuria as a continuous covariate provided a more accurate estimate of the treatment effect observed with losartan. The original stratum-adjusted analysis (9) failed to account for the imbalance in proteinuria values between the treatment groups within the high proteinuria stratum. Therefore, the manner by which a covariate highly correlated to outcome is adjusted can have a meaningful impact on the observed treatment difference.. The aim of a randomized clinical trial is not to determine the relationship between a covariate and the outcome variable; however, the relationship between a covariate and the outcome may affect the statistical analysis and thereby the ...

Background: A 59 year old male from the North was referred with Nephrotic Syndrome and heavy proteinuria (8gm) and weakness. Urine examination showed 2-3 pus cells, 4+ protein. Two cores of renal tissue were submitted in buffered formalin and Michels transport medium. Objective: The case is presented for its rarity. The discussion will include immunological review and glomerular patterns of injury associated with Microfilaria. Result: The immunofluorescence pattern was negative for IgG, IgM, IgA, C3, C4, C1q, kappa and lambda. The light microscopy revealed 3 glomeruli showing mild increase in mesangial cellularity. Tubules show cloudy change. Interstitium shows focal lymphoid infiltrate. An unusual finding is the presence of segmented microfilaria in glomerular capillaries. Conclusion: Diagnosis of filariasis on kidney biopsy by identifying microfilaria is rare. High index of suspicion is required to diagnose filariasis due to its wide range of clinical presentation and laboratory findings. In ...
Chronic kidney disease is diagnosed when there is evidence of kidney damage for at least 3 months or in any patient who has a GFR less than 60 mL/min for that same amount of time.[5][6]. To calculate GFR, three equations are commonly used (the MDRD, CKD-EPI and Cockcroft-Gault formula). However, the best estimate of GFR is the CKD-EPI equation, which adjusts for age, race, and gender. It is important to note, however, that the formula tends to underestimate the true GFR at a GFR greater than 60mL/min.. To quantitate albuminuria, a spot urine protein/creatinine ratio can be done. A value greater than 30 mg of albumin per gram of creatinine is considered abnormal while values greater than 300mg/g is considered severely impaired renal function. Additionally, a 24-hour urine protein can also be performed. A value greater than 3.5 g is concerning for nephrotic range proteinuria.. Further evaluation of kidney disease can include a renal ultrasound, CBC, BMP, urinalysis, and/or kidney biopsy. An ...

Background/Purpose: Lupus nephritis remains one of the most devastating SLE complications, occurring in over 50% of the patients. It is important to identify clinical conditions that precede nephritis for the purposes of patient care and to identify preventive strategies. Most previous studies of predictors of incident nephritis in SLE are cross-sectional or do not incorporate time-varying predictors. We leveraged a large clinical cohort which evaluated patients quarterly to identify fixed and time-varying predictors of lupus nephritis. Methods: Since 2006, the urine protein/creatinine ratio was measured quarterly in patients in our SLE cohort. This analysis was based on cohort follow-up after 2006 in patients who did not have a history of diabetes and who did not have a prior episode of sustained elevated proteinuria, nor a history of nephritis, renal insufficiency, or failure. Among these patients, we defined an incident case of proteinuria as two or more measures of urine protein/creatinine ...
Conventionally, proteinuria is diagnosed by a simple dipstick test, although it is possible for the test to give a false negative reading,[14] even with nephrotic range proteinuria if the urine is dilute.[citation needed] False negatives may also occur if the protein in the urine is composed mainly of globulins or Bence Jones proteins because the reagent on the test strips, bromophenol blue, is highly specific for albumin.[6][15] Traditionally, dipstick protein tests would be quantified by measuring the total quantity of protein in a 24-hour urine collection test, and abnormal globulins by specific requests for protein electrophoresis.[1][16] Trace results may be produced in response to excretion of Tamm-Horsfall mucoprotein. More recently developed technology detects human serum albumin (HSA) through the use of liquid crystals (LCs). The presence of HSA molecules disrupts the LCs supported on the AHSA-decorated slides thereby producing bright optical signals which are easily distinguishable. ...
Introduction: Proteinuria is a risk factor for cardiovascular (CV) disease in the general population and occurs commonly after kidney transplantation. The association between proteinuria and CV disease in this population has not been sufficiently evaluated, and it is not clear whether proteinuria reduction affects CVD disease risk. In this study we sought to evaluate the association between time varying proteinuria and the change in proteinuria over time and major adverse cardiovascular events (MACE) after kidney transplantation.. Patients and methods: we collected the routine dipstick urine protein evaluation results performed every three to six months in all patients at our post transplantation follow-up clinic. The follow-up time was divided into 6 months intervals and proteinuria was evaluated by using all available protein measurements during each interval. Urine protein concentration was defined as negative or positive according to the mean value during the six month interval. The primary ...
Title: NF-κB and Proteinuric Renal Disease. VOLUME: 2 ISSUE: 1. Author(s):Karina Drumm and Michael Gekle. Affiliation:Institute of Physiology University of Wuerzburg Roentgenring 9 D-97070 Wuerzburg, Germany. Keywords:renal proximal tubule, kidney, inflammation, albumin, proteinuria. Abstract: Chronic renal diseases with enhanced glomerular protein filtration are accompanied by tubulointerstitial inflammation and progression to renal function deterioration. Filtered protein, like albumin, is a pathogenic factor per se in the progression of renal diseases. The nuclear factor κB (NF-κB), a ubiquitous transcription factor, mediates the expression of numerous inflammatory or fibrotic mediators such as RANTES, MCP-1, TNF-α, cytokine receptors, or iNOS in renal as well as in other tissues. It is evident that NF-κB is involved in protein-overload stimulated renal inflammatory mechanisms. This paper reviews the recent studies concerning NF-κB-activation and expression inducing renal ...
Table 1: Effects of Moderate-to-Severe Impairment of the Estimated Glomerular Filtration Rate and of Proteinuria on the Central Hemodynamics and Arterial Stiffness in Middle-Aged Healthy Japanese Men
TY - JOUR. T1 - Profiling proteinuria in pediatric patients. AU - Abitbol, Carolyn L.. AU - Chandar, Jayanthi. AU - Onder, Ali Mirza. AU - Nwobi, Obioma. AU - Montané, Brenda. AU - Zilleruelo, Gastón. PY - 2006/7/1. Y1 - 2006/7/1. N2 - This study was designed to characterize proteinuria in children with kidney disease. Random urine samples from 250 pediatric patients were examined by quantitative measures of total protein (pr), albumin (Alb), and creatinine (cr). Patient diagnoses were subjectively categorized as Glomerular (GD) or Tubulo-interstitial disease (TD) in origin. Proteinuria was quantitated by the random urine protein-to-creatinine (Upr/cr) ratio, and glomerular proteinuria was assessed as the albumin-to-creatinine ratio (Ualb/cr) and percentage albuminuria (%Alb=Alb/pr* 100). The non-albumin fraction (1-Alb/ pr) includes low-molecular-weight proteins and micro- and macroglobulins. Of the 250 patients, 112 (45%) had GD and 138 (55%) had TD. Both proteinuria and albuminuria ...
Chronic kidney disease is often not associated with significant symptoms or abnormalities in common laboratory test results. Diagnosis is supposedly facilitated by calculating the glomerular filtration rate (GFR) from serum creatinine. A reference range GFR, however, does not exclude renal disease, because renal disease causes the subsequent decrease of renal function. Thorough analysis of proteinuria, however, requires a profound knowledge of the renal handling of the different marker proteins of glomerular and tubular origin. This paper summarizes the scientific basis, explains the diagnostic rationale and proves the concept by analyzing 5669 samples, where GFR and proteinuria work-up were available. 63% (1446 of 2287) of the samples with a GFR above 60 showed either glomerular (37.8%, n=865) or tubular proteinuria (25.4%, n= 581). The quantity of proteinuria increased severely with decreasing kidney function. The rate of glomerular proteinuria remained nearly constant in the different GFR ...
It has been suggested that the severity of proteinuria may be a factor in the progression of renal disease (20). For instance, proteinuria is correlated with interstitial inflammation and fibrosis (1,2,6), with renal disease progression (4), and with hypertension (3). A potential mechanism by which extensive proteinuria may lead to interstitial inflammation and fibrosis was recently demonstrated in the protein overload model in rats (6). In these animals, urine was found to contain a factor that was highly chemotactic for monocytes; this factor was present after 3 d of albumin loading and preceded the interstitial accumulation of inflammatory cells. This factor was characterized as a nonpolar lipid that is synthesized and released into the urine by PTC when challenged with lipid-replete albumin (6). More recently, proximal tubules metabolizing albumin were found to release closely related neutral lipid factors that stimulate transepithelial fluid secretion and cellular proliferation; ...

Proteinuria levels at 12 months are the best predictor of long-term renal outcome in patients with lupus nephritis, according to a study.
The above information should be taken into account when considering conversion from calcineurin inhibitors to Rapamune in stable renal transplant patients due to the lack of evidence showing that renal function improves following conversion, and the finding of a greater increment in urinary protein excretion, and an increased incidence of treatment-emergent nephrotic range proteinuria following conversion to Rapamune. This was particularly true among patients with existing abnormal urinary protein excretion prior to conversion.. In an open-label, randomized, comparative, multicenter study where kidney transplant patients were either converted from tacrolimus to sirolimus 3 to 5 months post-transplant (sirolimus group) or remained on tacrolimus, there was no significant difference in renal function at 2 years post-transplant. Overall, 44/131 (33.6%) discontinued treatment in the sirolimus group versus 12/123 (9.8%) in the tacrolimus group. More patients reported adverse events 130/131 (99.2%) ...
Persistent and increased leakage of protein in the urine (proteinuria) is abnormal. Circulating serum proteins are filtered by the glomerulus, and the small amount of protein that is present in the filtrate is passed through the glomerular capillary wall and reabsorbed by the proximal tubule. Although defects in tubular reabsorption of protein can also result in renal proteinuria (Fanconis syndrome), changes in glomerular permeability are what results in the most significant and highest urine protein concentrations. Thus, proteinuria is considered a key marker for renal dysfunction and characterizes the severity of the underlying kidney disease. Proteinuria is also an independent predictor for cardiovascular morbidity and mortality.In the past twenty years, major progress in our understanding of the molecular mechanisms leading to the development of proteinuria was made. Spearheaded by the discovery that proteins located at the slit diaphragm of the glomerulus play a crucial role in the proper function
Direct-acting Antivirals in Kidney Transplant Patients: Successful Hepatitis C Treatment and Short Term Reduction in Urinary Protein/Creatinine Ratios

106 patients (mean age 37 y, 74% men) with biopsy-proved IgA nephropathy, a serum creatinine level ≤ 265 µmol/L, and a urinary protein excretion rate ≥ 1 g/d or a 25% increase in serum creatinine level over the preceding 6 months. Exclusion criteria were systemic lupus erythematosus, chronic liver disease, antiglomerular basement membrane glomerulonephritis, pregnancy, and lactation. 75 patients (71%) continued to receive treatment throughout the study ...
BACKGROUND: Proteinuria has emerged as an important vascular risk factor for adverse cardiovascular events including stroke. Hypertension has been proposed as the principal confounder of this relationship but its role has not been systematically examined. AIM: We aimed to determine if proteinuria remains an independent predictor of stroke after more complete adjustment for blood pressure. SUMMARY OF REVIEW: We performed a systematic review, searching MEDLINE and EMBASE (to February 2018) for cohort studies or randomized controlled trials that reported stroke incidence in adults according to baseline proteinuria ± glomerular filtration rate. Study and participant characteristics and relative risks were extracted. Estimates were combined using a random effects model. Heterogeneity was assessed by χ 2 statistics and I2, and by subgroup strata and meta-regression, with a particular focus on the impact of more complete adjustment for blood pressure on the association. The quality of cohort studies and post
We got the preliminary results back on Sams kidney biopsy from the nurse practitioner. We still havent heard back from our nephrologist (!!!), so we have a lot of unanswered questions. It was not what we were expecting at all. The most common cause of nephrotic range proteinuria in kids is minimal change disease, something that responds pretty well to a course of steroids. That wouldve been good news. The bad news we predicted was that the biopsy would show scarring from cystinosis, something irreversible and an indicator of progressive kidney dysfunction, likely requiring transplant earlier in life. What we found was a whole new version of bad news. ...
Background: Markers of kidney dysfunction such as proteinuria or albuminuria have been reported to be associated with coronary heart disease, but the consistency and strength of any such relationship has not been clearly defined. This lack of clarity has led to great uncertainty as to how proteinuria should be treated in the assessment and management of cardiovascular risk. We therefore undertook a systematic review of published cohort studies aiming to provide a reliable estimate of the strength of association between proteinuria and coronary heart disease. Methods and Findings: A meta-analysis of cohort studies was conducted to obtain a summary estimate of the association between measures of proteinuria and coronary risk. MEDLINE and EMBASE were searched for studies reporting an age- or multivariate-adjusted estimate and standard error of the association between proteinuria and coronary heart disease. Studies were excluded if the majority of the study population had known glomerular disease or ...

High - resolution two - dimension electrophoresis technique for protein with silver staining was used to characterise urinary high density lipoprotein (HDL) - apolipoproteins. Sequential ultracentrufugation method was used to isolate urinary lipoprotein particles of the same density as serum HDL. Immunostaining of electroblotted proteins further confirmed the presence of HDL-Apos in urine. HDL - Apolipoprotein A-I, A-II and C were identified in urine of normal subjects, diabetic patients and patients with biopsy proven glomerular proteinuria. An in-house ELISA method was used to quantify urinary HDL - Apo A - I. Selectivity indices were also determined.
Results:. The eGFR was over than or equal to 60 mL/min/m2 of body surface in 75 % of the patients and was independent of the natural history of lupus. 53,3 % of the patients showed proteinuria value over 0,15 g in 24 hours. The 24-hour proteinuria value exponentially increased as the eGFR decreased. The longer the natural history of the disease, the higher the values of proteinuria. The behavior of the proteinuria value in 24 hours was similar to that observed with the albuminuria value in 24 hours. ...
Bevacizumab Increases Risk for Severe Proteinuria in Cancer Patients, a recent paper in JASN 2010 talks about a systemic and meta analysis of this drug in prior trials. An interest to me is this field of onco-nephrology where chemotherapy agents are causing damage and we can really learn a lot from them about podocyte biology. As we all know now that anti VEGF agents like the above mention cause proteinuria via similar mechanism as seen in pre eclampsia. Its podocytopenia. This paper analyzed 16 studies of over 12,000 patients and different tumors. When avastin was added to other chemo agents, the degree of proteinuria was significantly higher. The cancer with the highest proteinuria risk was renal cell cancer. this might be because usually these individuals getting this drug already have a nephrectomy decreasing their nephron mass. ...
Despite multiple causes, Chronic Kidney Disease is commonly associated with proteinuria. A previous study on Non Obese Diabetic mice (NOD), which spontaneously develop type 1 diabetes, described histological and gene expression changes incurred by diabetes in the kidney. Because proteinuria is coincident to diabetes, the effects of proteinuria are difficult to distinguish from those of other factors such as hyperglycemia. Proteinuria can nevertheless be induced in mice by peritoneal injection of Bovine Serum Albumin (BSA). To gain more information on the specific effects of proteinuria, this study addresses renal changes in diabetes resistant NOD-related mouse strains (NON and NOD.B10) that were made to develop proteinuria by BSA overload. Proteinuria was induced by protein overload on NON and NOD.B10 mouse strains and histology and microarray technology were used to follow the kidney response. The effects of proteinuria were assessed and subsequently compared to changes that were observed in a prior

When the patients acute kidney injury (AKI) was discovered, he was evaluated to find the etiology of AKI. He had low serum phosphorus (3.2 mg/dL), low uric acid (3.4 mg/dL), low potassium (2.8 mg/dL) and low total carbon dioxide (16 mmol/L) levels. Although his serum glucose level was less than 200 mg/dL, he had glycosuria (glucose 4+ on a urine dipstick). His urine pH was 5.5, and he had non-albuminuric proteinuria (urine protein/creatinine ratio 1.94, urine microalbumin/creatinine ratio 0.18). Serum protein electrophoresis showed polyclonal gammopathy. Parathyroid hormone and 25-hydroxyvitamin D levels were within normal range. Neither dual-energy X-ray absorptiometry nor the whole body bone scan were performed. Because of the sudden azotemia with hypophosphatemia, hypokalemia, metabolic acidosis, glycosuria and non-albuminuric proteinuria, we suspected proximal renal tubular damage. Kidney Doppler ultrasonography was performed to exclude other causes of AKI. Both kidneys had normal ...

The cats included in the cross-sectional epidemiological study were also enrolled in a longitudinal study of survival time. Proteinuria proved to be significantly and independently associated with survival, as were age and plasma creatinine concentration. No association was found between gender or systolic blood pressure and survival. For illustrative purposes, the survival curves for cats with variable magnitude of proteinuria and adjusted for any influence of creatinine concentration and age are depicted in the figure (above right).. The results of these studies demonstrate that proteinuria is associated with shortened survival times in cats with naturally occurring kidney disease. However, because only about half of the cats suffering from CKD in our clinic population die or are euthanatized because of progressive renal failure or an acute uraemic crisis, rapid decline in renal function may not be the sole reason for the decreased survival times in cats with proteinuria. In human beings with ...
BACKGROUND Proteinuria is considered an unfavorable clinical condition that accelerates renal and cardiovascular disease. However, it is not clear whether all forms of proteinuria are damaging. Mutations in CUBN cause Imerslund-Gräsbeck syndrome (IGS), which is characterized by intestinal malabsorption of vitamin B12 and in some cases proteinuria. CUBN encodes for cubilin, an intestinal and proximal tubular uptake receptor containing 27 CUB domains for ligand binding.METHODS We used next-generation sequencing for renal disease genes to genotype cohorts of patients with suspected hereditary renal disease and chronic proteinuria. CUBN variants were analyzed using bioinformatics, structural modeling, and epidemiological methods.RESULTS We identified 39 patients, in whom biallelic pathogenic variants in the CUBN gene were associated with chronic isolated proteinuria and early childhood onset. Since the proteinuria in these patients had a high proportion of albuminuria, glomerular diseases such as ...

A urine protein test is a diagnostic procedure to detect the content of protein in a persons urine like Urobilinogen in urine cloudy or milky urine. The test is primarily used in the diagnosis of kidney damage and kidney diseases.. It is also called the 24-Hour Urine Protein test or the Urine Protein to Creatinine Ratio (UPCR) test. When referring to specific protein detection, it is called a Proteinuria test or a Microalbuminuria test. Urine samples can be random or collected over a period of time (every 4 hours or for 24 hours).. Detecting traces of proteins in urine excretion is a sign that something is wrong with the kidney or the liver, the organs that filter waste products and flush them out of the body. Proteins are building blocks of the body and ideally absorbed 100%. As such, when a protein passes out of the body through urine, it is a sign of a kidney having problems by not being able to hold back the proteins.. Urine protein tests will determine albuminuria, the initial stage of ...

This study demonstrated that paraquat toxicity was associated with development of albuminuria in clinical and experimental nephrotoxicity. In turn, albuminuria was associated with increased excretion of renal biomarkers and modified biomarker sensitivity in outcome prediction. The data confirm that concentrations of the low molecular weight protein biomarkers, CysC, OstP, β2M, KIM-1 and NGAL increased in the presence of albuminuria. Albuminuria was also associated with mortality. To our knowledge, this is the first study to evaluate the influence of albuminuria on excretion of all Predictive Safety Testing Consortium (PSTC) qualified urinary biomarkers.. The influence of proteinuria and albuminuria on uNGAL, uCysC and uIL-18 concentration was previously evaluated in a heterogeneous intensive care unit patient population [26] where many fold increases in uNGAL and uCysC were seen in the presence of proteinuria or albuminuria. That study and others have highlighted that proteinuria and ...

The late histologic findings in diarrhea-associated hemolytic uremic syndrome. Moghal, NE, Ferreira MAS, Howie AJ, Milford DV, Raafat F, Taylor CM. Journal of Pediatrics 1998;133(2):220-223.. ABSTRACT:. Although survivors of diarrhea-associated hemolytic uremic syndrome (D+HUS) may initially appear to have made a full recovery, long-term studies reveal a significant number have renal sequelae. This paper examines the histologic findings in children with persistent proteinuria after D+HUS and discusses the importance of long-term follow-up of these patients. Kidney biopsies were undertaken for persisting proteinuria (mean 5.4 years) from the onset of D+HUS in five boys and two girls (mean age at onset 3 years). At one year the mean early morning urine protein/creatinine ratio was 100 mg/mmol, and the mean glomerular filtration rate (GFR) was 65 mL/min/1.73m2 . At five years the mean early morning urine protein/creatinine ratio was 81 mg/mmol, and the mean GFR was 73 mL/min/1.73m2. The biopsy ...
Spinal-cord injury patients may develop proteinuria as a result of glomerulosclerosis due to urosepsis, hydronephrosis, vesicoureteric reflux, and renal calculi. medicines to reduce intravesical pressure, are at high risk for developing reflux nephropathy. When such individuals develop glomerulosclerosis due to recurrent urosepsis, renal calculi, or hydronephrosis, risk of proteinuria is definitely improved further. Take home message: (1) Screening for proteinuria should be performed regularly in the at-risk individuals. (2) In the absence of additional renal diseases causing proteinuria, spinal cord injury individuals with significant proteinuria may be prescribed angiotensin-converting enzyme inhibitor or angiotensin-II receptor antagonist to sluggish progression of chronic renal disease and reduce the risk of cardiovascular mortality. and combined anaerobes. After antibiotic therapy, a stent was inserted in right ureter. Extracorporeal shockwave lithotripsy was performed, which resulted in ...

A recent collaborative meta-analysis by Kidney Disease: Improving Global Outcomes reported that an estimated glomerular filtration rate (eGFR) ,60 mL/min/1.73m 2 and an albumin-to-creatinine ratio of ≥10 mg/g were independent predictors for mortality in the general population. However, selection bias, heterogeneity of the cohorts and measurement issues could be limitations.Methods.We analyzed the relationship of eGFR and proteinuria with mortality in the Korean general population, represented by 112115 participants, aged ≥20 years, who had a voluntary health check-up with homogenous calibration of ...
A patient with Laurence-Moon-Biedl syndrome and nephrotic range proteinuria is presented. Radiological investigation of the urinary tract revealed clubbed calyces but no evidence of obstruction or vesicoureteric reflux. Renal biopsy revealed occasional sclerotic glomeruli, extensive foot-process fusion and segmental glomerular basement membrane abnormalities with negative immunofluorescence for immunoglobulins and complement. Nephrotic proteinuria responded to steroid therapy but mild proteinuria persisted. The findings were consistent with minimal change nephropathy superimposed on the glomerular lesions of Lawrence-Moon-Biedl syndrome.. ...
The link between lifestyle modification and changes in both proteinuria and estimated glomerular filtration rates (eGFRs) was evaluated in Japanese subjects with proteinuria who were not taking medications. We used data from 51 men (35.8±10.0 years) and 74 women (38.0±11.0 years) with proteinuria at baseline and a 1-year follow up. eGFR was defined by a new equation developed specifically for Japanese subjects. Subjects were given advice for dietary and lifestyle improvement at the initial appointment. At the 1-year follow up, eGFR was increased in both sexes, but not at significant levels. (men:p=0.7709, women:p=0.2180). Proteinuria was also improved in many subjects. A decrease in proteinuria may be associated with improving eGFR in Japanese ...
Proteinuria in children can be transient, orthostatic, or pathologic. Transient proteinuria (often associated with fever or exercise) does not indicate underlying renal disease. Orthostatic proteinuria (elevated protein excretion when the subject is upright but normal protein excretion in recumbent position) occurs most commonly in school-aged children and rarely exceeds 1 g/m2/day. These patients do not have hematuria and have normal values of estimated glomerular filtration rate and C3 complement. Pathologic proteinuria is likely if proteinuria is associated with hematuria and/or the first morning urine protein-to-creatinine ratio is >0.2 in older children. Nephrotic-range proteinuria is defined as levels >40 mg/m2/h in 24 hours. ...

Renal toxicity has been reported with bisphosphonates such as pamidronate and zolidronate but not with ibandronate, in the treatment of breast cancer patients with bone metastasis. One of the patterns of bisphosphonate-induced nephrotoxicity is focal segmental glomerulosclerosis (FSGS) or its morphological variant, collapsing focal segmental glomerulosclerosis (CFSGS). We describe a breast cancer patient who developed heavy proteinuria (protein/creatinine ratio 9.1) and nephrotic syndrome following treatment with oral ibandronate for 29 months. CFSGS was proven by biopsy. There was no improvement 1 month after ibandronate was discontinued. Prednisone and tacrolimus were started and she experienced a decreased in proteinuria. In patient who develops ibandronate-associated CFSGS, proteinuria appears to be at least partially reversible with the treatment of prednisone and/or tacrolimus if the syndrome is recognized early and ibandronate is stopped.
It is of interest that Gordon and Gill [1] explained some causes of microalbuminuria in living donors after nephrectomy such as inadequate pretransplant evaluation and conditions related to the poverty of unrelated donors. However, most reported data suggest that proteinuria increased in the living kidney donor population, and the prevalence of microalbuminuria in living donors varied from 11.5% to 34% in different studies [3, 4]. In addition, a study showed that 56% of 152 donors developed mild proteinuria (>150?mg/day) [5]. One meta-analysis demonstrated that the average proteinuria was 154?mg/day and concluded that kidney donation results in small increases in urinary protein [6]. The suggested causes of proteinuria postnephrectomy were subclinical hyperfiltration damage of the glomeruli, hypertension and a lower glomerular filtration rate.. Finally, it is generally accepted that all kidney donors should be screened for microalbuminuria at 2- to 3-year intervals postkidney donation because ...

METHODS: We conducted a retrospective chart review of all adult patients, age ,18 years seeing a nephrologist with a diagnosis of CKD stage 4 or 5 during the study period between 06/01/2011 and 08/31/2013 to evaluate the placement of an AV access, initiation of dialysis and we conducted a survey of providers about the process.. RESULTS: The 221 patients (56% female) in the study had median age of 66 years (interquartile range (IQR), 57-75) and were followed for a median of 1.26 years (IQR 0.6-1.68). At study entry, 81%had CKD stage 4 and 19% had CKD stage 5. By the end of study, 48 patients had initiated dialysis. Thirty-four of the patients started dialysis with a catheter (1 failed and 10 maturing AVFs), 9 with an AVF and 5 with an AVG. During the study period, 61 total AV accesses were placed (54 AVF and 7 AVG). A higher urinary protein/ creatinine ratio and a lower eGFR were associated with AV access placement and dialysis initiation. A greater number of nephrology visits were associated ...

Proximal tubule (PT) dysfunction, including tubular proteinuria, is definitely a substantial complication in youthful sickle cell disease (SCD) that may eventually result in chronic kidney disease. binding towards the Hb dimer-dimer user interface inhibits Hb binding to megalin/cubilin. BLAST queries and structural modeling analyses exposed parts of similarity between Hb and albumin that map to the region and could represent sites of Hb discussion with megalin/cubilin. Our research claim that impaired endocytosis of megalin/cubilin ligands, than heme toxicity rather, may be the reason for tubular proteinuria in SCD individuals. Additionally, lack of these filtered protein in to the urine may donate to the extra-renal pathogenesis of SCD. solid course=kwd-title Keywords: megalin, proteinuria, proximal tubule, sickle cell disease, supplement D sickle cell disease (SCD) can be a damaging disease caused by an individual mutation (Glu7Val) in hemoglobin (Hb) that triggers reddish colored ...
The drinks a person with Proteinuria problem can consume - #Proteinuria happens when the kidneys are not healthy enough to hold the protein to not leak out through urine. Protein is vital for our overall health. Albumin is a protein in the blood which is profitable for the strong bones and muscles. Healthy #kidneys work to filter and eliminate extra fluid and waste materials from the blood. Kidneys also work on to maintain the flow of protein and important nutrients in the blood. When the kidneys are not healthy enough to not eliminate albumin protein through urine, the condition is known as protein leakage and protein loss. When the protein leaks out through urine is also is known as Proteinuria or #Albuminuria and its also can be a sign of the nephrotic syndrome. The three main causes of Proteinuria are- 1. Diabetes, 2. High Blood Pressure, and 3. Kidney Disease Following are the symptoms of Proteinuria or Protein Loss 1. Foamy or bubbly urine 2. Problem in urination 3. Frequent or less urine ...

Angiopoietin-like protein 3(ANGPTL3) is well acknowledged as a key regulator of lipid metabolism. Now, there have not been enough data to explain the mechanism of hyperlipidemia related proteinuria. In this study, we hoped to investigate the changes of Angiopoietin-like protein 3(ANGPTL3) levels in hyperlipidemia patients with different proteinuria levels. Seventy-one patients with hyperlipidemia were selected, who were hospitalized in Gansu Provincial Peoples Hospital from September 2016 to September 2017, and 20 healthy people in the physical examination center were selected. We combed through medical history and conducted clinical biochemical indicators of blood urea nitrogen (BUN), serum creatinine (SCr), 24 h urine protein quantitation (24hUPro), cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low detection of density lipoproteins (LDL-C). The concentration of serum ANGPTL3 was measured by ELISA. 1. Serum ANGPTL3 in patients with hyperlipidemia related proteinuria was

29 patients with IgA nephropathy whose proteinuria persisted at a level of 2.0 g/day or more and who received prednisolone treatment for 1-3 years were retrospectively evaluated on their clinical courses. 13 of 14 patients with renal dysfunction of less than 70 ml/min in initial creatinine clearance (C|sub|cr|/sub|) values subsequently entered a progressive course during a follow-up period of 47 months, leading to end-stage renal failure in 8 cases. On the other hand, only 1 of the other 15 patients with preserved renal function of 70 ml/min or more ended up with end-stage renal failure during a follow-up period of 74 months, although 7 underwent a progressive course. Three patients in the latter group experienced a prominent reduction in proteinuria to less than 1.0 g/day and maintained renal function. Meanwhile, the steroid group of moderate proteinuric patients with a creatinine clearance greater than 70 ml/min had a benign course, while the nonsteroid group had an unfavorable one. These results

TY - JOUR. T1 - The Familial Occurrence of Focal Segmental Glomerular Sclerosis. AU - McCurdy, Fredrick A.. AU - Butera, Philip J.. AU - Wilson, Ronald. PY - 1987/1/1. Y1 - 1987/1/1. N2 - We have observed the occurrence of focal segmental glomerulosclerosis in all three siblings of a single Hispanic family. Each of the children had the onset of significant proteinuria on or before the age of 10. The two oldest children have had progression of their disease to end-stage with subsequent successful transplantation. The youngest sibling continues to have normal renal function. All three patients had renal biopsies prior to the onset of renal insufficiency and each of the biopsies showed the presence of focal segmental glomerulosclerosis with mild diffuse mesangial hypercellularity. Finally, HLA-typing revealed the presence of DRw8 in all three siblings and the father. This report further suggests that genetic factors may be quite important in the development of the lesion of focal segmental ...

Results HSN occurred in 102/223 (46%) patients, consisting of isolated haematuria in 14%, isolated proteinuria in 9%, both haematuria and proteinuria in 56%, nephrotic-range proteinuria in 20% and nephrotic-nephritic syndrome in 1%. The patients who developed HSN were significantly older than those who did not (8.2±3.8 vs 6.2±3.0 years, p,0.001, CI for the difference 1.1 to 2.9). Nephritis occurred a mean of 14 days after HSP diagnosis, and within 1 month in the majority of cases. The risk of developing HSN after 2 months was 2%. Prednisone prophylaxis did not affect the timing of the appearance of nephritis. The risk factors for developing nephritis were age over 8 years at onset (OR 2.7, p=0.002, CI 1.4 to 5.1), abdominal pain (OR 2.1, p=0.017, CI 1.1 to 3.7) and recurrence of HSP disease (OR 3.1, p=0.002, CI 1.5 to 6.3). Patients with two or three risk factors developed nephritis in 63% and 87% of cases, respectively. Laboratory tests or blood pressure measurement at onset did not predict ...
TY - JOUR. T1 - Reduction in proteinuria attenuates hyperlipidemia in the nephrotic syndrome. AU - Kaysen, George. AU - Davies, R. William. PY - 1990/11. Y1 - 1990/11. N2 - Hyperlipidemia in the nephrotic syndrome is characterized by increased synthesis of lipids as well as reduced removal of lipids from the blood. When rats with nephrotic syndrome are fed a 40% protein diet, urinary albumin excretion and rate of albumin synthesis increase. Serum cholesterol and triglyceride concentration increase as well. If the increase in albuminuria, but not the increase in the rate of albumin synthesis resulting from dietary protein augmentation, is prevented by the administration of enalapril, serum triglyceride and cholesterol concentration are not increased but are reduced nearly to within the normal range. Proteinuria, and not an increased rate of albumin synthesis, thus plays a causal role in nephrotic hyperlipidemia. Therapy directed at correcting altered glomerular permselectivity, while perserving ...
Despite the occurrence of relapses, steroid sensitive nephrotic syndrome (SSNS) has a good long term prognosis. As it often heralds a clinical relapse, significant proteinuria (+++ or more on albustix) for ⩾3 consecutive days (simplified as P3D in this letter) defines a relapse, resulting in steroid therapy before the onset of oedema. Proteinuria may be triggered by viral infections1 and does not always develop into a relapse.2. We have observed 24 consecutive episodes of asymptomatic P3D, without oedema, occurring during a viral illness, in four children (two boys, two girls, age range 2-5 years) known to have SSNS. In eight of these episodes, the families refused to rush with steroid therapy; serum albumin level remained ,30 g/l in the three where measured, and the proteinuria resolved between 5 and 10 days. Sixteen other episodes occurred in three children, who were treated as relapses; all three were later labelled as frequent relapsers and started on long term steroid therapy. None ...
Background: Proteinuria is considered as an unfavorable clinical condition that accelerates renal and cardiovascular disease. However, it is not clear if all forms of proteinuria are damaging. Mutations in CUBN cause Imerslund-Gräsbeck syndrome (IGS) featured by intestinal malabsorption of vitamin B12 and in some cases proteinuria. CUBN encodes for cubilin, an intestinal and proximal tubular uptake receptor containing 27 CUB domains for ligand binding. Methods: We used next-generation sequencing for renal disease genes to genotype cohorts of patients with suspected hereditary renal disease and chronic proteinuria. CUBN variants were analyzed using bioinformatics, structural modeling and epidemiological methods. Results: We identified 39 patients, in whom biallelic pathogenic variants in the CUBN gene are associated with chronic isolated proteinuria with childhood onset. Since the proteinuria displayed a high proportion of albuminuria, glomerular diseases such as steroid-resistant nephrotic ...

The most common form of glomerulonephritis is IgA nephropathy. Previous studies have demonstrated the efficacy of immunosuppressive therapy to target mesangial IgA deposits and circulating IgA autoantibodies for the treatment of IgA nephropathy.. In patients who have proteinuria with urinary protein excretion of ,1 g per day, the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend treatment with a blocker of the renin-angiotensin system (an angiotensin-converting-enzyme inhibitor or an angiotensin II-receptor blocker).. The KDIGO guidelines also suggest the use of systemic glucocorticoids in patients with a proteinuria level above 1 g of urinary protein excretion per day and a glomerular filtration rate (GFR) higher than 50 mL per minute despite supportive care. However, according to Thomas Rauen, MD, and colleagues, findings from earlier randomized, controlled trials leading to these suggestions have been criticized because the blockade of the renin-angiotensin system was ...

BACKGROUND About 30-40% of diabetic patients who developed nephropathy have lipoprotein disorders, especially lipoprotein a [Lp(a)], which is related to atherosclerosis. OBJECTIVES The aim of this study was to investigate the effect of N-acetyl cysteine (NAC) on the serum levels of Lp(a) and amount of proteinuria in a group of type 2 diabetic patients with diabetic nephropathy. PATIENTS AND METHODS A total of 40, type 2 diabetic (T2D) patients, patients with proteinuria, were randomly divided into two groups. The experimental group was treated by NAC (1200 mg/day) for two months in conjunction with conventional treatment for diabetes and hypertension. Control group received routine medications. RESULTS No significant change was identified in serum Lp(a) during treatment with NAC (P ,0.05). However, NAC decreased the amount of proteinuria, serum triglyceride (TG) level and systolic blood pressure in experimental group compared to the control group (P ,0.05). CONCLUSIONS These findings suggest ...

Fanconi-Bickel syndrome, caused by mutations in SLC2A2 encoding the glucose transporter 2 (GLUT2), is characterized by generalized proximal renal tubular dysfunction manifesting in late infancy. We describe phenotypic heterogeneity of Fanconi-Bickel syndrome in three siblings, including early and atypical presentation with transient neonatal diabetes mellitus in one. The second-born of a non-consanguineous couple, evaluated for polyuria and growth retardation, had rickets, hepatomegaly and proximal tubular dysfunction from 4 to 6 months of age. A male sibling, who expired at 4 months, also had hepatomegaly and growth retardation. The third sibling had polyuria, glucosuria and mild proteinuria on day 3 of life. Hyperglycemia was detected 2 weeks later, which required therapy with insulin for 3 months. Mild metabolic acidosis was present at 2 weeks; hypercalciuria, phosphaturia and aminoaciduria were seen at 6 months. Sanger sequencing showed a homozygous missense mutation in SLC2A2 (exon 7, ...
TY - JOUR. T1 - Proteinuria and hypertension with tyrosine kinase inhibitors. AU - Kandula, Praveen. AU - Agarwal, Rajiv. PY - 2011/12/2. Y1 - 2011/12/2. N2 - Tyrosine kinases are important for the development of pathological angiogenesis, a critical factor for survival and proliferation of tumor cells. Inhibition of tyrosine kinases either through targeted binding of its ligands or inhibition of its receptor has led to significant hindrance in angiogenesis and has improved survival for several cancers. Several of these antibodies or small molecules have been approved for treatment of recurrent and resistant cancers over the last decade. Although generally well tolerated, tyrosine kinase inhibitors have been linked with development of hypertension and proteinuria. We review the literature for incidence and severity of hypertension and proteinuria among several tyrosine kinase inhibitors, their pathophysiologic mechanisms, and provide a guide for screening and management..

Collapsing glomerulopathy (CGP) is a pattern of kidney injury seen on renal biopsy with multiple associations and etiologies. It is most commonly described in African-Americans and others with recent African ancestry. The disease is rapidly progressive and often presents with abrupt onset of renal failure and nephrotic-range proteinuria. Since its description 30 years ago, this entity has transformed from a morphologic diagnosis typically seen in the setting of HIV infection to a complicated diagnosis with numerous etiologies, many of which are associated with underlying apolipoprotein L1 (APOL1)-risk variants or other genetic disorders ...
2014 S. Karger AG, Basel. Background: Proteinuria is a cardinal sign of chronic kidney disease, which is a major healthcare problem that affects millions of people worldwide. Recent advances in molecular genetics and cell biology have revealed the podocyte as the primary functional regulator of the tri-layered glomerular filter. Since podocyte foot processes (FP) and their interposed slit diaphragms (SD) form the final barrier to protein loss, podocyte injury causes proteinuric kidney disease.Summary: A fundamental mechanism of proteinuric glomerular diseases is podocyte FP effacement and the loss of podocyte SD integrity, both of which involve the active rearrangement of the podocyte actin cytoskeleton. Initially, these early changes are reversible, but later can progress to cell detachment and death. Based on the importance of the actin cytoskeleton for podocyte development and the maintenance of the glomerular filter, podocyte research is heavily focused on studying actins molecular make-up ...
BACKGROUND: Proteinuria is included in the Kidney Disease: Improving Global Outcomes (KDIGO) risk stratification for chronic kidney disease (CKD) in the general population. However, the importance of proteinuria in patients with renal cancer has not been adequately studied. OBJECTIVE: To evaluate the prognostic impact of preoperative proteinuria on overall survival (OS) and renal function stability (RFS) for patients managed with renal cancer surgery. DESIGN, SETTING, AND PARTICIPANTS: From 1999 to 2008, 977 patients who underwent renal cancer surgery had preoperative data recorded for the glomerular filtration rate (GFR) estimated using the CKD Epidemiology Collaboration equation (G1 ≥90, G2 60-89, G3a 45-59, G3b 30-44, G4 15-29, and G5 ,15ml/min/1 ...
Nephrotic-range proteinuria is defined as urinating more than 3.5 grams of protein per day. Thats 25 times the normal amount, and is the primary indicator of the nephrotic syndrome - a group of diseases that damage the kidneys filtering system.. Researchers at the Glasgow Royal Infirmary in the United Kingdom looked at the effect of omega-3 fatty acids. (more…). ...
In order to evaluate the progression of renal disease, Munich-Wistar rats were submitted to 5/6 nephrectomy and given whole-body x- or gamma -irradiation with or without remnant kidney protection or were submitted only to remnant kidney irradiation. All groups received a single 6-Gy dose immediately after surgery. Whole-kidney function, glomerular hemodynamics, 24-hour proteinuria and histopathology were assessed 60 days after surgery and irradiation. the irradiated nephrectomized animals presented whole-kidney function parameters comparable to those of normal rats. in addition, they were less hypertensive and had higher hematocrit. They showed glomerular hyperfiltration and hypertension even greater than their respective nephrectomized controls. However, the interrelations among the glomerular filtration determinants were somewhat different in irradiated animals. Their 24-hour proteinuria was significantly lower and the sclerosis index and tubulointerstitial injury score were markedly smaller. ...
Renal injury may result in excess excretion of protein, called proteinuria. Urine protein electrophoresis helps determine the type of kidney injury.

The literature explaining the relationship between urinary protein excretion and risk of cardiovascular disease and renal disease is rapidly proliferating. glomerulopathy in AAs [34-36] was quickly sophisticated using markers determined in the Yoruba inhabitants through the 1000 Genomes Task. Coding variations in the adjacent gene proven stronger association using the proteinuric kidney disease FSGS (coding variations in werent recognized after good mapping). FSGS regularly manifests nephrotic symptoms with progressive lack of kidney function an impact that may be accelerated in the current presence of HI infection. In comparison the same polymorphisms will also be connected with focal global glomerulosclerosis the condition historically related to hypertension (previously tagged hypertensive nephrosclerosis or hypertension-attributed end-stage renal disease). Focal global glomerulosclerosis is normally seen as a low-level or regular albuminuria the contrary of whats observed in FSGS. The gene ...
