Late referral of end-stage renal failure. (1/7078)

We studied all new patients accepted for renal replacement therapy (RRT) in one unit from 1/1/96 to 31/12/97 (n = 198), to establish time from nephrology referral to RRT, evidence of renal disease prior to referral and the adequacy of renal management prior to referral. Sixty four (32.3%, late referral group) required RRT within 12 weeks of referral. Fifty-nine (29.8%) had recognizable signs of chronic renal failure > 26 weeks prior to referral. Patients starting RRT soon after referral were hospitalized for significantly longer on starting RRT (RRT within 12 weeks of referral, median hospitalization 25.0 days (n = 64); RRT > 12 weeks after referral, median 9.7 days (n = 126), (p < 0.001)). Observed survival at 1 year was 68.3% overall, with 1-year survival of the late referral and early referral groups being 60.5% and 72.5%, respectively (p = NS). Hypertension was found in 159 patients (80.3%): 46 (28.9%) were started on antihypertensive medication following referral, while a further 28 (17.6%) were started on additional antihypertensives. Of the diabetic population (n = 78), only 26 (33.3%) were on an angiotensin-converting-enzyme inhibitor (ACEI) at referral. Many patients are referred late for dialysis despite early signs of renal failure, and the pre-referral management of many of the patients, as evidenced by the treatment of hypertension and use of ACEI in diabetics, is less than optimal.  (+info)

Mycophenolate mofetil prevents the progressive renal failure induced by 5/6 renal ablation in rats. (2/7078)

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)

Serum levels of 1,25-dihydroxyvitamin D, 24,25-dihydroxyvitamin D, and 25-hydroxyvitamin D in nondialyzed patients with chronic renal failure. (3/7078)

BACKGROUND: In patients with chronic renal failure (CRF), abnormalities in vitamin D metabolism are known to be present, and several factors could contribute to the abnormalities. METHODS: We measured serum levels of three vitamin D metabolites, 1,25(OH)2D, 24, 25(OH)2D and 25(OH)D, and analyzed factors affecting their levels in 76 nondialyzed patients with CRF (serum creatinine> 1.6 and < 9.0 mg/dl), 37 of whom had diabetes mellitus (DM-CRF) and 39 of whom were nondiabetic (nonDM-CRF). RESULTS: Serum levels of 1,25(OH)2D were positively correlated with estimated creatinine clearance (CCr; r = 0.429; P < 0.0001), and levels of 24,25(OH)2D were weakly correlated with CCr (r = 0.252, P < 0.05); no correlation was noted for 25(OH)D. Serum levels of all three vitamin D metabolites were significantly and positively correlated with serum albumin. Although there were no significant differences in age, sex, estimated CCr, calcium and phosphate between DM-CRF and nonDM-CRF, all three vitamin D metabolites were significantly lower in DM-CRF than in nonDM-CRF. To analyze factors influencing vitamin D metabolite levels, we performed multiple regression analyses. Serum 25(OH)D levels were significantly and independently associated with serum albumin, presence of DM and serum phosphate (R2 = 0.599; P < 0.0001). 24,25(OH)2D levels were significantly and strongly associated with 25(OH)D (beta = 0.772; R2 = 0.446; P < 0.0001). Serum 1,25(OH)2D levels were significantly associated only with estimated CCr (R2 = 0. 409; P < 0.0001). CONCLUSIONS: These results suggest that hypoalbuminemia and the presence of DM independently affect serum 25(OH)D levels, probably via diabetic nephropathy and poor nutritional status associated with diabetes, and that 25(OH)D is actively catalyzed to 24,25(OH)2D in CRF, probably largely via extrarenal 24-hydroxylase. Serum levels of 1,25(OH)2D were significantly affected by the degree of renal failure. Thus, this study indicates that patients with CRF, particularly those with DM, should receive supplements containing the active form of vitamin D prior to dialysis.  (+info)

Plasma total homocysteine and cysteine in relation to glomerular filtration rate in diabetes mellitus. (4/7078)

BACKGROUND: The plasma concentrations of total homocysteine (tHcy) and total cysteine (tCys) are determined by intracellular metabolism and by renal plasma clearance, and we hypothesized that glomerular filtration is a major determinant of plasma tHcy and tCys. We studied the relationships between the glomerular filtration rate (GFR) and plasma tHcy and tCys in populations of diabetic patients with particularly wide ranges of GFR. METHODS: We measured GFR, urine albumin excretion rate (UAER), plasma tHcy, tCys, methionine, vitamin B12, folate, C-peptide, and routine parameters in 50 insulin-dependent diabetes mellitus (IDDM) and 30 non-insulin-dependent diabetes mellitus (NIDDM) patients. All patients underwent intensive insulin treatment and had a serum creatinine concentration below 115 micromol/liter. RESULTS: Mean plasma tHcy in diabetic patients (0.1 micromol/liter) was lower than in normal persons (11.1 micromol/liter, P = 0.0014). Mean plasma tCys in diabetic patients (266.1 micromol/liter) was also lower than in normal persons (281.9 micromol/liter, P = 0.0005). Seventy-three percent of the diabetic patients had relative hyperfiltration. Plasma tHcy and tCys were closely and independently associated with GFR, serum folate, and serum B12. However, plasma tHcy was not independently associated with any of the 22 other variables tested, including age, serum creatinine concentration, UAER, total daily insulin dose, and glycemic control. CONCLUSIONS: Glomerular filtration rate is an independent determinant of plasma tHcy and tCys concentrations, and GFR is rate limiting for renal clearance of both homocysteine and cysteine in diabetic patients without overt nephropathy. Declining GFR explains the age-related increase in plasma tHcy, and hyperfiltration explains the lower than normal mean plasma tHcy and tCys concentrations in populations of diabetic patients.  (+info)

HIV-associated nephropathy is a late, not early, manifestation of HIV-1 infection. (5/7078)

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. (6/7078)

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)

Renal failure predisposes patients to adverse outcome after coronary artery bypass surgery. VA Cooperative Study #5. (7/7078)

BACKGROUND: More than 600,000 coronary artery bypass graft (CABG) procedures are done annually in the United States. Some data indicate that 10 to 20% of patients who are undergoing a CABG procedure have a serum creatinine of more than 1.5 mg/dl. There are few data on the impact of a mild increase in serum creatinine concentration on CABG outcome. METHODS: We analyzed a Veterans Affairs database obtained prospectively from 1992 through 1996 at 14 of 43 centers performing heart surgery. We compared the outcome after CABG in patients with a baseline serum creatinine of less than 1.5 mg/dl (median 1.1 mg/dl, N = 3271) to patients with a baseline serum creatinine of 1.5 to 3.0 mg/dl (median 1.7, N = 631). RESULTS: Univariate analysis revealed that patients with a serum creatinine of 1.5 to 3.0 mg/dl had a higher 30-day mortality (7% vs. 3%, P < 0.001) requirement for prolonged mechanical ventilation (15% vs. 8%, P = 0.001), stroke (7% vs. 2%, P < 0.001), renal failure requiring dialysis at discharge (3% vs. 1%, P < 0.001), and bleeding complications (8% vs. 3%, P < 0.001) than patients with a baseline serum creatinine of less than 1.5 mg/dl. Multiple logistic regression analyses found that patients with a baseline serum creatinine of less than 1.5 mg/dl had significantly lower (P < 0.02) 30-day mortality and postoperative bleeding and ventilatory complications than patients with a serum creatinine of 1.5 to 3.0 mg/dl when controlling for all other variables. CONCLUSION: These results demonstrate that mild renal failure is an independent risk factor for adverse outcome after CABG.  (+info)

Effect of fasting on temporal variation in the nephrotoxicity of amphotericin B in rats. (8/7078)

Evidence for temporal variation in the nephrotoxicity of amphotericin B was recently reported in experimental animals. The role of food in these variations was determined by studying the effect of a short fasting period on the temporal variation in the renal toxicity of amphotericin B. Twenty-eight normally fed and 28 fasted female Sprague-Dawley rats were used. Food was available ad libitum to the fed rats, while the fasted animals were fasted 12 h before and 24 h after amphotericin B injection to minimize stress for the animals. Water was available ad libitum to both groups of rats, which were maintained on a 14-h light, 10-h dark regimen (light on at 0600 h). Renal toxicity was determined by comparing the levels of excretion of renal enzyme and the serum creatinine and blood urea nitrogen (BUN) levels at the time of the maximal (0700 h) or the minimal (1900 h) nephrotoxicity after the intraperitoneal administration of a single dose of dextrose (5%; control group) or amphotericin B (50 mg/kg of body weight; treated group) to the rats. The nephrotoxicities obtained after amphotericin B administration at both times of day were compared to the nephrotoxicities observed for time-matched controls. In fed animals, the 24-h urinary excretion of N-acetyl-beta-D-glucosaminidase and beta-galactosidase was significantly higher when amphotericin B was injected at 0700 and 1900 h. The excretion of these two enzymes was reduced significantly (P < 0.05) in fasting rats, and this effect was larger at 0700 h (P < 0.05) than at 1900 h. The serum creatinine level was also significantly higher (P < 0.05) in fed animals treated at 0700 h than in fed animals treated at 1900 h. Fasting reduced significantly (P < 0.05) the increase in the serum creatinine level, and this effect was larger in the animals treated at 0700 h. Similar data were obtained for BUN levels. Amphotericin B accumulation was significantly higher (P < 0.05) in the renal cortexes of fed rats than in those of fasted animals, but there was no difference according to the time of injection. These results demonstrated that fasting reduces the nephrotoxicity of amphotericin B and that food availability is of crucial importance in the temporal variation in the renal toxicity of amphotericin B in rats.  (+info)

Creatinine is a metabolic waste product, removed from the blood by the kidneys, and excreted in the urine. The measurement of creatinine is used in the assessment and monitoring of many medical conditions as well as in the determination or adjustment of absorbed dosage of pesticides. Earlier models to predict 24-hour urinary creatinine used ordinary least squares regression and assumed that the subjects observations were uncorrelated. However, many of these studies had repeated creatinine measurements for each of their subjects. Repeated measures on the same subject frequently are correlated. Using data from the NIOSH-CDC Pesticide Dose Monitoring in Turf Applicators study, this thesis project built a model to predict 24-hour urinary creatinine using the Mixed Model methodology. A covariance structure, that permitted multiple observations for any one individual to be correlated, was identified and utilized. The predictive capabilities of this model were then compared to the earlier models
In most of time, creatinine refers to serum creatinine. Actually, there is also a term urine creatinine. In contrast, serum creatinine is more scientific than urine creatinine. Serum creatinine is widely used in many countries, and we can express it in 2 ways, the units of which are mg/ dL and umol/L. The normal range of serum creatinine is 44 -103 umol/L and we can also say 0.5-1.2mg/ dL. Here, we should also note that every lab has its own specific measure and even in the same country, different labs also have different measures for the machines are different.How to Reduce High Creatinine Level in Blood ...

When it comes to creatinine, we will think of urine creatinine and serum creatinine. Whats the relationship between them? To answer this question, we should first figure out what is creatinine. Creatinine is a kind of substances which comes into being due to the metabolism of muscles in our body. Creatinine level is influenced by diet, the amount of exercise, and so on. It comes into being into blood or exactly speaking serum, and then is discharged out together with urine. So from the above, we can get a conclusion that the more creatinine in urine, the less creatinine in serum. How to Reduce High Creatinine Level in Blood ...
Background: The changes in serum creatinine level after Percutaneous coronary Intervention has been reported by different authors..

A few (4,5), but not all (19,20), studies have suggested that reduced kidney function may be an important risk factor for mortality in patients with HF. In one study (4), patients in the lowest quartile of creatinine clearance had almost three times the risk of mortality of patients in the highest quartile.. The level of GFR is usually regarded as the best overall index of the level of kidney function. Serum creatinine is determined by a number of factors, other than GFR, such as gender, age, muscle mass and ethnicity and, therefore, provides only a rough estimate of level of kidney function (21). To provide a more accurate measure of kidney function, we estimated GFR using a recently validated formula from the MDRD study (12,13). In patients with reduced kidney function, this formula has been shown to be a more accurate measure of kidney function than serum creatinine or creatinine clearance estimated using either the Cockcroft Gault equation or measured creatinine clearance using 24-h urine ...

1) A chemical waste molecule that is generated from muscle metabolism. Creatinine is produced from creatine, a molecule of major importance for energy production in muscles. Approximately 2% of the bodys creatine is converted to creatinine every day. Creatinine is transported through the bloodstream to the kidneys. The kidneys filter out most of the creatinine and dispose of it in the urine. Although it is a waste, creatinine serves a vital diagnostic function. Creatinine has been found to be a fairly reliable indicator of kidney function. As the kidneys become impaired the creatinine will rise. Abnormally high levels of creatinine thus warn of possible malfunction or failure of the kidneys, sometimes even before a patient reports any symptoms. It is for this reason that standard blood and urine tests routinely check the amount of creatinine in the blood. Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dl) in adult males and 0.5 to 1.1 ...

If everybody makes creatinine, why do doctors check creatinine blood levels? As I said, creatinine is normally filtered out of the blood by the kidneys. This means that creatinine levels in the blood of a healthy person are quite stable. However, if for some reason (like, say, lupus) the kidneys are not functioning well, then they will be unable to filter the blood properly. This will lead to creatinine build-up, as muscles continue to make creatinine but the kidneys are not removing it from the blood. So the creatinine test serves as a basic test to see if the kidneys are working properly or not. If you have high creatinine levels then the answer is most likely, or not, and in a lupus patient this means that your disease is active and is interfering with your kidneys ...

Creatinine is a chemical waste product of creatine. Creatine is a chemical the body makes to supply energy, mainly to muscles.. By comparing the creatinine level in urine with the creatinine level in blood, this test estimates the glomerular filtration rate (GFR). GFR is a measure of how well the kidneys are working, especially the kidneys filtering units. These filtering units are called glomeruli.. Creatinine is removed, or cleared, from the body entirely by the kidneys. If kidney function is abnormal, creatinine level increases in the blood because less creatinine is released through the urine.. ...
What is creatinine? Creatinine is a chemical waste molecule that is generated from muscle metabolism. Creatinine is produced from creatine, a molecule of major importance for energy production in muscles.Approximately 2% of the bodys creatine is converted to creatinine every day. Creatinine is transported through the bloodstream to the kidneys. The kidneys filter out most of the creatinine and dispose of it in the urine.Because the muscle mass in the body is relatively constant from day to day, the creatinine production normally remains essentially unchanged on a daily basis. The normal range of creatinine in blood is: 0.6 to 1.2 mg/dL (or 53 to 106 mcmol/L) for males, and 0.5 to 1.1 mg/dL (or 44 to 97 mcmol/L) for females.  Men usually have higher levels than women because creatinine increases with muscle mass.Factors that contribute to high creatinine levels include dehydration or inadequate water intake; medications like ACE inhibitors, NSAIDs, chemotherapy drugs and ...
Glomerular Filtration Rate (GFR) Based on Creatinine Measurement. Glomerular Filtration Rate (GFR) is a calculation of how efficiently the kidneys are able to filter wastes from the blood. One way of determining GFR requires the injection of a substance into the bloodstream that is later measured in the urine which is collected for a 24-hour period. However, scientists found they could calculate GFR with less trouble, without an injection or a 24-hour urine collection. The calculation -- called the eGFR -- requires a measurement of creatinine in a blood sample. (The e in eGFR stands for estimated) In a laboratory, a persons blood is tested to see how much creatinine is in the blood. Creatinine levels in the blood can vary, and each laboratory has its own normal range. A person whose creatinine level is only slightly above this range will probably not feel sick, but the elevation is a sign that the kidneys are not working at full strength. But because creatinine values differ so much from ...
When the kidneys are functioning normally, the amount of creatinine in the serum should keep even. If the they are not working properly, the level of serum creatinine will becomes elevated. This level is usually used to determine how well ones kidneys are functioning. Normal levels of blood creatinine are about 0.6~1.2 mg/dL in adult male and 0.5~1.1 mg/dL in adult female. For individuals with PKD, will exercise and weight loss affect their levels of creatinine in the blood ...

Glomerular hyperfiltration is not able to be detected in clinical practice. We assessed whether hyperfiltration is associated with albuminuria progression among Indigenous Australians at high risk of diabetes and kidney disease to determine its role in kidney disease progression. Longitudinal observational study of Indigenous Australians aged ≥18 years recruited from ,20 sites, across diabetes and/or kidney function strata. At baseline, iohexol clearance was used to measure glomerular filtration rate (mGFR) and hyperfiltration was defined as (i) a mGFR of ≥125 mL/min/1.73 m2, and (ii) an age-adjusted definition, with the top 10% of the mGFR for each 10 year age group at baseline. Baseline and follow-up urine albumin-to-creatinine ratio (uACR) was collected, and linear regression was used to assess the associations of hyperfiltration and uACR at follow up. 407 individuals (33% men, mean age 47 years) were followed-up for a median of 3 years. At baseline, 234 had normoalbuminuria and 173 had ...

Objective: The purpose of the study was to establish the reference ranges of measured creatinine clearance and estimated creatinine clearance for adult Kenyan population. Method: A prospective study carried out in clinical chemistry laboratory of Kenyatta National Hospital involving 265 healthy individuals between 18-60years. Reference ranges were constructed by using the parametric methods to estimate 2.5 and 97.5 percentiles of distribution as lower and upper reference limits. The glomerular filtration rate assessment of the adult healthy Kenyan population was carried out by investigating serum creatinine (SrCr), 24 hours urine creatinine clearance (Mcrcl), estimated creatinine clearance (Ecrcl), urine creatinine (UCr) and urine volume (UV). Two hundred and sixty five voluntarily study subjects comprising of 106 male and 159 females were recruited in the study. Results: Sex related reference values were established as follows:- SrCr [male:68-128), female: 60-122] umol/l, Mcrcl [male:52-110), ...

We compared random urine ACR with 4-hour AER in a large, well-characterized population with type 1 diabetes. Despite moderate correlation between ACR and AER, there were systematic differences in these measurements, altered classification of prevalent albuminuria states and changes in albuminuria states over time, and differences in within-individual variability. These findings have important implications for clinical practice and research, supporting the use of consistent ascertainment methods over time and further efforts to standardize and optimally interpret measurement of urine albumin excretion.. It has previously been recognized that ACR values are biased in relation to AER by determinants of urine creatinine excretion, particularly gender (2). Creatinine is generated in muscle, and urinary excretion is the main disposition for generated creatinine, so muscle mass is a major determinant of urine creatinine excretion (17-20). Because men have greater muscle mass than women, men have ...
Correct estimation of glomerular filtration rate (GFR) is necessary in critically ill patients in order to asses renal function. GFR is subsequently used to derive and appropriate drug dosing of renally excreted drugs and warrant adequate dose adaptations.. It is known that estimation of GFR based on creatinine clearance is not precise, especially in populations with altered muscle mass or instable renal function, such as the Intensive Care Unit (ICU) population.. The use of combined filtration markers together, cystatin C and creatinine, can improve precision in estimating GFR (eGFR). Studies confirmed that eGFR based on both creatinine and cystatin C is more precise than eGFR creatinine or eGFR cystatin C. The equation based on both creatinine and cystatin C, the Chronic Kidney Disease Epidemiology Collaboration creatinine-cystatin C (CKD-EPIcr-cys), may therefore improve eGFR and thus drug dosing in ICU patients, a population that does not reach PK/PD targets frequently.. So far little is ...
Endothelial dysfunction, a marker of cardiovascular (CV) risk, is common in human immunodeficiency virus (HIV)-infected patients. Microalbuminuria is frequent in HIV-infected patients, and is a predictor of renal impairment and CV risk. We investigated the association between microalbuminuria and endothelial dysfunction among HIV-infected patients receiving highly-Active antiretroviral therapy (HAART). Endothelial function, measured by brachial artery flow-mediated dilatation (bFMD), and urine albumin-To-creatinine ratio (UACR), were measured in 170 HAART-Treated HIV-infected adults. The relationship between UACR and bFMD was evaluated. The prevalence of increased UACR, defined by two cut-off levels (20 mg/g and 30 mg/g), was 29 and 17. UACR was significantly higher while bFMD was lower among patients with metabolic syndrome (MS). UACR was associated with bFMD (r = â 0.31; p , 0.001). This association was stronger in MS-patients (r = â 0.44; p = 0.003). UACR above 20 mg/g was associated with ...
Regardless of the recent advancements in the understanding of the pathophysiology of acute kidney injury (AKI), its diagnosis remains fundamentally dependent on the serum creatinine (sCr) level and urine output (UO), both of which are considered late markers of AKI, offering only a vague idea of the actual creatinine clearance (CrCl). Although not ideal, CrCl is still the most common alternative of the glomerular filtration rate (GFR) in clinical practice. It is generally accepted that early diagnosis of AKI must reveal kidney impairment before sCr increases. Much effort has been made to find tubular and glomerular markers of injury which increase (in blood and/or in urine) before the official diagnosis of AKI. Most of these markers are expensive and not widely available, especially in developing countries. Urine creatinine (CrU), the major link between sCr and UO, has been systematically ignored and clinicians are usually unaware of its value. The reasons for this are unclear, but it may be related
Title: Prediction of Glomerular Filtration Rate From Body Cell Mass and Plasma Creatinine. VOLUME: 1 ISSUE: 3. Author(s):Carlo Donadio, Cristina Consani, Michela Ardini, Francesca Caprio, Giulia Grassi and Annalisa Lucchesi. Affiliation:Division of Nephrology, Department of Internal Medicine, University of Pisa, I-56100 Pisa, Italy.. Keywords:glomerular filtration rate, estimate of renal function, plasma creatinine, body composition, electrical body impedance, body cell mass, renal excretion of drugs, renal failure. Abstract: The gold standards for the measurement of glomerular filtration rate (GFR) are inulin clearance and radioisotopic methods. However, creatinine clearance is the most used test to evaluate GFR in clinical practice. Its adequacy is questionable, since its repeatability is quite poor, mainly due to errors in the collection of urine. The aim of this study was to evaluate a new method to predict GFR from the body cell mass (BCM) and plasma creatinine (Pcr), avoiding urine ...

The main objective of assessing urine calcium excretion is to establish whether this is inappropriately high in the presence of a low plasma calcium. Reference values for urine calcium/creatinine ratio in young children are not well defined and will vary according to factors such as diet. The upper limit of normal (∼97th centile) for fasting urine calcium excretion in healthy children greater than 2 years of age in the United Kingdom is 0.69 mmol/mmol,19 but values may be greater than this in infancy. In the presence of hypocalcaemia a urine calcium/creatinine ratio greater than 0.3 mmol/mmol on spot samples suggests inappropriate excretion.20 A timed 24 hour urinary calcium excretion (collected in containers with hydrochloric acid to prevent precipitation of calcium salts) can be obtained in the older child. Hypercalciuria is suggested by values greater than 0.1 mmol/kg/day.21 Timed urine collection can be difficult in young children, and a random spot urine calcium creatinine ratio repeated ...
INTRODUCTION: Perioperative Ischaemic Evaluation-2 (POISE-2) is an international 2×2 factorial randomised controlled trial of low-dose aspirin versus placebo and low-dose clonidine versus placebo in patients who undergo non-cardiac surgery. Perioperative aspirin (and possibly clonidine) may reduce the risk of postoperative acute kidney injury (AKI). METHODS AND ANALYSIS: After receipt of grant funding, serial postoperative serum creatinine measurements began to be recorded in consecutive patients enrolled at substudy participating centres. With respect to the study schedule, the last of over 6500 substudy patients from 82 centres in 21 countries were randomised in December 2013. The authors will use logistic regression to estimate the adjusted OR of AKI following surgery (compared with the preoperative serum creatinine value, a postoperative increase ≥26.5 μmol/L in the 2 days following surgery or an increase of ≥50% in the 7 days following surgery) comparing each intervention to placebo, ...
OBJECTIVES: Both renal disease and systemic inflammation predict non-AIDS-defining events and overall mortality in HIV-infected patients. Here, we sought to determine the relationships between renal disease and circulating inflammation markers.. METHODS: We performed a secondary analysis of AIDS Clinical Trials Group Study A5224s to determine if markers of renal disease [urine protein:creatinine ratio (uPCR), urine albumin:creatinine ratio (uACR), and estimated glomerular filtration rate (eGFR), using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine and cystatin C-creatinine] were associated with markers of systemic inflammation [high-sensitivity C-reactive protein, interleukin-6, tumour necrosis factor (TNF)-α, soluble TNF-α receptor I (sTNFRI), sTNFRII, and soluble vascular cellular and intercellular adhesion molecules]. We correlated these renal and inflammatory markers prior to antiretroviral initiation and after 96 weeks of therapy.. RESULTS: We found that eGFR ...

If the kidney function is affected adversely by the disease, it will cause renal function decline. Elevated creatinine will be the result of pyelonephritis.
Estimation of GFR (eGFR) using formulae based on serum creatinine concentrations are commonly used to assess kidney function. Physical exercise can increase creatinine turnover and lean mass; therefore, this method may not be suitable for use in exercising individuals. Cystatin-C based eGFR formulae may be a more accurate measure of kidney function when examining the impact of exercise on kidney function. The aim of this study was to assess the agreement of four creatinine and cystatin-C based estimates of GFR before and after a 12-month exercise intervention. One hundred forty-two participants with stage 3-4 chronic kidney disease (CKD) (eGFR 25-60 mL/min/1.73 m2) were included. Subjects were randomised to either a Control group (standard nephrological care [n = 68]) or a Lifestyle Intervention group (12 months of primarily aerobic based exercise training [n = 74]). Four eGFR formulae were compared at baseline and after 12 months: 1) MDRDcr, 2) CKD-EPIcr, 3) CKD-EPIcys and 4) CKD-EPIcr-cys. Control
Researchers from Canada showed that using serum creatinine (SCr) values obtained at the time of hospital admission is a reliable method for assessment of acute kidney injury (AKI).. In the study Diagnosis and outcomes of acute kidney injury using surrogate and imputation methods for missing preadmission creatinine values, published in BMC Nephrology, the authors aimed to find a surrogate method to determine SCr baseline levels that can allow more accurate assessment of AKI diagnosis and outcomes.. Diagnoses and predictions of AKI disease outcomes rely on the calculation of the glomerular filtration rate (GFR). Such determination requires patients pre-admission SCr values. However, these parameters are frequently missing and are a common obstacle to evaluate this condition.. In the study, the authors evaluated four alternative methods to determine SCr values and compared them to the standard and most reliable method, which is blood measurement before hospital admission. They used an estimation ...

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 ...
The standard indicators of renal function are serum levels of urea nitrogen and creatinine; their ratio is normally about 10:1. This ratio may increase when renal perfusion or urine flow is decreased, as in urinary tract obstruction or dehydration. Because serum urea nitrogen levels are more affected by these and other factors (eg, nitrogen intake, catabolism, use of corticosteroids) than are creatinine levels, the most reliable single indicator of glomerular function is the serum level of creatinine. For example, an increase in serum creatinine from 0.5 to 1.0 mg/dL represents a 50% decrease in GFR (glomerular filtration rate). Norms for serum creatinine relate to muscle mass. Therefore, only larger adolescents should have levels exceeding 1 mg/dL. Serum cystatin C has been proposed to be a more reliable indicator of glomerular function but may be less widely available, with variable reference ranges in the pediatric population and invalid values observed in the setting of corticosteroid ...
Macroalbuminuria can be diagnosed using a dipstick test. Microalbuminuria is detected using a spot urine sample (positive if 30 to 300 mg/L) or 24-hour urine collection (positive if 30 - 300 mg/24 hours).. At least two out of three measurements over a three to six months period confirms the diagnosis of microalbuminuria [3]. Early morning sample is preferred.. Another method of measuring microalbuminuria is urine albumin/creatinine ratio (ACR). It is positive if ACR ,3.5 mg/mmol (female) or ,2.5 mg/mmol (male). This method will compensate variations in urine concentration in spot-check sample.. Patient should refrain from heavy exercises 24 hours before the test. The test is inaccurate in individuals with too much or too little muscle mass. ...

Hypercalciuria is a major cause of urolithiasis in adults and has reached increasing attendance in childhood. Traditionally urinary excretion of calcium is evaluated by 24-hour urine collection. Previous reports proposed the urinary calcium/urinary creatinine ratio (Ca/Cr-ratio) to diagnose hypercalciuric states. In 10 children with normocalciuria and 8 children with hypercalciuria the values of calcium excretion and Ca/Cr-ratio in a 24-hour urine collection were compared. 40 analyses showed a significant correlation (p = 0.001, r = 0.91) and hypercalciuria (urinary calcium greater than 4 mg/kg/day) is present if the Ca/Cr-ratio exceeds 0.23 (mg/mg). In 10 of the 18 patients the Ca/Cr-ratio of the 24-hour collection was compared with the Ca/Cr-ratio of a random urine sample collected 3 hours after breakfast. No significant difference was present. In 9 of 10 patients the correct diagnosis (normocalciuria or hypercalciuria) was possible by evaluation of this random urine sample. Our studies ...
Acute kidney injury (AKI) is common among intensive care unit (ICU) patients. AKI is highly heterogeneous, with variable links to poor outcomes. Current approaches to classify AKI severity and identify patients at highest risk for poor outcomes focus on the maximum change in serum creatinine (SCr) values. However, these scores are hampered by the need for a reliable baseline SCr value and the absence of a component differentiating transient from persistent rises in SCr. We hypothesized that identification of resolving or nonresolving AKI subphenotypes based on the early trajectory of SCr values in the ICU would better differentiate patients at risk of hospital mortality. We performed a secondary analysis of two prospective studies of ICU patients admitted to a trauma ICU (group 1; n = 1914) or general medical-surgical ICUs (group 2; n = 1867). In group 1, we tested definitions for resolving and nonresolving AKI subphenotypes and selected the definitions resulting in subphenotypes with the greatest
INTRODUCTION: Across the globe, human immunodeficiency virus (HIV) infection is a healthcare problem. Dyslipidemia, a cardiovascular risk factor, is known to occur with the progression of HIV infection. The factors which influence dyslipidemia in HIV subjects have not been completely identified. The aim of this study was to evaluate serum lipids and identify the factors which might influence dyslipidemia in treatment-na ve HIV subjects in Owerri, Nigeria. METHODS: this was a cross-sectional study of treatment-na ve HIV subjects. Anthropometric and demographic data were collected. Serum LDL serum cholesterol, serum high density lipoprotein cholesterol, serum triglyceride, spot urine creatinine, spot urine osmolality, spot urine protein, serum creatinine, 24-hour urine protein, 24-hour urine osmolality, 24-hour urine creatinine, creatinine clearance and hemoglobin were conducted. The variables were compared between those who have dyslipidemia and those who have no dyslipidemia. RESULTS: the mean age of
important to understand that the functional capacity of the filtering system of the kidneys determines the creatinine clearance, which is the norm during sample Rehberg indicate normal kidney.. However, some diseases do not lead to changes in this indicator (eg, chronic pyelonephritis).. creatinine level in blood depends on the activity of its endogenous synthesis and on its rate of urinary excretion.It is important to understand that this figure depends not only on active filter systems, but also the speed and volume of re-absorption of substances in the formation of primary urine.. So now sample Rehberg (determining creatinine clearance) found quite widely used in diagnostic medicine.Direct relationship between renal function and clearance provides high diagnostic value of the procedure.. ...

Renal failure in type 2 diabetes is truly a medical catastrophe of worldwide dimension (1): In all countries of the western world, diabetes, mostly type 2, has become the most frequent comorbid condition in patients admitted for renal replacement therapy. It had long been recognized that the classical features of diabetic nephropathy, so well documented in type 1 diabetes (2,3), are not present in patients with type 2 diabetes and impaired renal function in an equally uniform fashion. In the third NHANES survey, Kramer et al. (4) noted that retinopathy and albuminuria (spot urine albumin/creatinine ratio) were absent in 30% of elderly type 2 diabetic patients with eGFR ,60 ml/min per 1.73 m2 (2) (Modification of Diet in Renal Disease [MDRD] formula). In several independent local surveys we found that 15 to 20% of type 2 diabetic patients reaching end-stage renal failure lacked major proteinuria and had shrunken kidneys, raising the unproven assumption of ischemic nephropathy (5). It is well ...

For microalbuminuria screening in patients with diabetes, measuring urinary albumin concentration (UAC) in random urine samples offers sensitivity and specificity similar to those of the albumin-to-creatinine ratio (ACR), reports a study in JAMA Internal Medicine.A meta-analysis was performed with the use of data on 2078 patients from 14 studies evaluating UAC and ACR in random urine samples. All studies included 24-hour urine collections as the criterion standard for diagnosis of microalbuminuria.

Early kidney disease is asymptomatic and strongly associated with morbidity and mortality, hence an accurate estimation of kidney function is crucial for its diagnosis. In turn, an appropriate diagnosis and treatment of chronic and acute kidney disease depends on early detection. Currently markers like blood concentrations of creatinine and Cystatin-C are used to estimate glomerular filtration rate, and others as proteinuria help to assess renal damage, but all of these have different limitations indicating the need for new biomarkers that can discriminate and detect damage, especially in the most critical situation during the development of kidney disease. Given that kidneys are the most important excretory organ, changes in blood concentration levels of a wide variety of metabolites can be a reflection of reduction of kidney function and renal damage. An ideal biomarker for renal disease has to be able to predict early diagnosis of kidney disease, allowing for identification of the type and ...
A new spectrophotometric method for the analysis of creatinine concentration in human serum samples is developed. The method explores the oxidation of p-methylamino phenol sulfate (Metol) in the presence of copper sulfate and creatinine which yields an intense violet colored species with maximum absorbance at 530nm. The calibration graph of creatinine by fixed time assay ranged from 4.4 to 620μM. Recovery of creatinine in human serum samples varied from 101 to 106. Limit of detection and limit of quantification were 0.145μM and 0.487μM respectively. Sandells sensitivity was 0.112μgcm−2 and molar absorptivity was 0.101×104Lmol−1cm−1. Within day precision was 2.5-4.8 and day-to-day precision range was 3.2-7.8. The robustness and ruggedness of the method expressed in RSD values ranged from 0.78 to 2.12 and 1.32 to 3.46 respectively, suggesting that the developed method was rugged. This method provides good sensitivity and is comparable to standard Jaffes method with comparatively less ...
