Azotemia: A biochemical abnormality referring to an elevation of BLOOD UREA NITROGEN and CREATININE. Azotemia can be produced by KIDNEY DISEASES or other extrarenal disorders. When azotemia becomes associated with a constellation of clinical signs, it is termed UREMIA.Uremia: A clinical syndrome associated with the retention of renal waste products or uremic toxins in the blood. It is usually the result of RENAL INSUFFICIENCY. Most uremic toxins are end products of protein or nitrogen CATABOLISM, such as UREA or CREATININE. Severe uremia can lead to multiple organ dysfunctions with a constellation of symptoms.Blood Urea Nitrogen: The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.

Elimination occurs as a result of metabolic processes in the kidney, liver, saliva, sweat, intestine, heart, brain, or other site.Injections, Intravenous: Injections made into a vein for therapeutic or experimental purposes.Models, Biological: Theoretical representations that simulate the behavior or activity of biological processes or diseases. For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.Area Under Curve: A statistical means of summarizing information from a series of measurements on one individual. It is frequently used in clinical pharmacology where the AUC from serum levels can be interpreted as the total uptake of whatever has been administered. As a plot of the concentration of a drug against time, after a single dose of medicine, producing a standard shape curve, it is a means of comparing the bioavailability of the same drug made by different companies.

It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.Receptors, Dopamine D2: A subfamily of G-PROTEIN-COUPLED RECEPTORS that bind the neurotransmitter DOPAMINE and modulate its effects. D2-class receptor genes contain INTRONS, and the receptors inhibit ADENYLYL CYCLASES.Receptors, Dopamine D1: A subfamily of G-PROTEIN-COUPLED RECEPTORS that bind the neurotransmitter DOPAMINE and modulate its effects.

A scoring system to predict renal outcome in IgA nephropathy: from a nationwide prospective study. (1/22)

BACKGROUND: Immunoglobulin A (IgA) nephropathy is the most common form of glomerulonephritis in the world, and a substantial number of patients develop end-stage renal disease (ESRD). Although there are several prognostic indicators, it remains difficult to predict the renal outcome in individual patients. METHODS: A prospective cohort study was conducted in 97 clinical units in Japan from 1995 to 2002. We analysed the data from 2269 patients using proportional hazards models in order to determine the predictors of ESRD in IgA nephropathy and to develop a scoring system to estimate ESRD risk. RESULTS: During the follow-up (median, 77 months), 207 patients developed ESRD. Systolic hypertension, proteinuria, hypoproteinaemia, azotaemia and a high histological grade at initial renal biopsy were independently associated with the risk of ESRD. Mild haematuria predisposed patients to ESRD more than severe haematuria. A scoring system was developed to estimate the 7-year ESRD risk from eight clinical and pathological variables. Actually, this prognostic score accurately classified patients by risk: patients with estimates of 0.0-0.9, 1.0-4.9, 5.0-19.9, 20.0-49.9, and 50.0-100.0% had a 0.2, 2.4, 12.2, 40.2 and 80.8% of ESRD incidence over 7 years, respectively. The corresponding area under the receiver operating characteristic curve was 0.939 [95% confidence interval (CI), 0.921-0.958]. This score was verified in repetitions of the derivation-validation technique. CONCLUSIONS: Although the quality of some data collected by the mail survey is limited and the influence of therapy could not be considered, this scoring system will serve as a useful prognostic tool for IgA nephropathy in clinical practice.  (+info)

Clinical research on navel application of Shehuang Paste combined with Chinese herbal colon dialysis in treatment of refractory cirrhotic ascites complicated with azotemia. (2/22)

AIM: To explore the efficacy and mechanism of a novel therapeutic method of traditional Chinese medicine in patients with refractory cirrhotic ascites complicated with azotemia. METHODS: Seventy-five cases of refractory cirrhotic ascites complicated with azotemia were randomly divided into 3 groups: comprehensive treatment (n = 29), simple treatment (n = 24), and control (n = 22). The basic treatment methods were the same in all groups, including liver protecting medicines, diuretics and supportive drugs. The control group underwent only the basic treatment. Shehuang Paste (SHP) was applied to the navels of the two treatment groups once a day for 30 d. Colon dialysis with Chinese herbs was administered to the comprehensive treatment group once every two days. Before and after treatment, we measured abdominal circumference, BUN, Cr, serum Na+, urine Na+/K+, liver function, endotoxin content, NO, and ET-1. Color Doppler ultrasonography was conducted to measure the portal vein blood flow. RESULTS: The total effective rate for ascites was 72.4% in the comprehensive treatment group, 45.8% in the simple treatment, contrasting with 18.2% in the controls. Between the two treatment groups and the controls, there were significant differences in the effective rates (P < 0.01, and P < 0.05). There was also a significant difference (P < 0.05) between the two treatment groups. Measurements of Cr and BUN showed higher values for the treatment groups, with the comprehensive better than the simple group (P < 0.05). Sera Na, urine Na/K were different, P < 0.01 between pre- and post-treatment in the comprehensive group, and P < 0.05 in the simple group. The treatment groups' endotoxin content was also significantly reduced (P < 0.01, and P < 0.05), with the comprehensive group better than the simple group (P < 0.05). Portal vein blood flow and NO content significantly reduced (P < 0.05), as did ET-1 content (P < 0.01). There were no significant changes in the control group (P > 0.05). The comprehensive treatment group's pre- and post-treatment portal vein and splenic vein blood flows showed a positive correlation to NO, ET-1 and endotoxin contents. CONCLUSION: When treating refractory cirrhotic ascites complicated with azotemia, Shehuang Paste combined with Chinese herbal dialysis is better than Shehuang Paste alone for ascites resolution, azotemia, and endotoxin elimination. However, both methods on their own were also effective for reducing portal and splenic vein blood flow, and lowering the contents of NO, ET-1 in the two treatment groups.  (+info)

A preliminary report of brain edema in patients with uremia at first hemodialysis: evaluation by diffusion-weighted MR imaging. (3/22)

BACKGROUND AND PURPOSE: The dynamics of brain-water content associated with hemodialysis in patients with severe azotemia remains obscure. To investigate whether either interstitial or cytotoxic edema is responsible for dialysis disequilibrium syndrome (DDS), we used diffusion-weighted MR imaging (DWI) to measure the apparent diffusion coefficient (ADC), which is sensitive for detecting tissue water dynamics. METHODS: Eight consecutive patients with end stage renal disease (ESRD) and blood urea nitrogen level of more than 100 mg/dL (160.9 +/- 53.1 mg/dL) were recruited. Conventional MR images, DWI, and clinical manifestations were obtained before and after the 1st hemodialysis. The ADC values were determined for regions of normal-appearing gray and white matter and for regions of hyperintensity of white matter on T2-weighted MR imaging. RESULTS: Foci of bright areas of white matter were found in all patients on T2-weighted images. The ADC values of the patients with ESRD, in white matter and gray matter before and after hemodialysis, were greater than those of the healthy controls (P < .005). Regarding the impact of hemodialysis, the ADC of frontal lobe white matter increased significantly after hemodialysis (1.09 +/- 0.11 versus 1.03 +/- 0.11, P = .036). We did not find the specific area of brain edema reported in posterior leukoencephalopathy and the osmotic demyelination syndrome. CONCLUSIONS: These results suggest that severe azotemia in end stage renal disease leads to interstitial brain edema reflected as increased ADC, and the further increased ADC reflects that edema associated with 1st hemodialysis is interstitial rather than cytotoxic in nature.  (+info)

Carbon dioxide digital subtraction angiography-assisted endovascular aortic aneurysm repair in the azotemic patient. (4/22)

OBJECTIVE: This report analyzes the safety and efficacy of carbon dioxide digital subtraction angiography (CO(2)-DSA) for EVAR in a group of patients with renal insufficiency compared with a concurrent group of patients with normal renal function undergoing EVAR with iodinated contrast angiography (ICA). METHODS: Between 2003 and 2005, 100 consecutive patients who underwent EVAR using ICA, CO(2)-DSA, or both were retrospectively reviewed, and preoperative, intraoperative, postoperative, and follow-up variables were collected. Patients were divided into two groups depending on renal function and contrast used. Group I comprised patients with normal renal function in whom ICA was used exclusively, and group II patients had a serum creatinine >or=1.5 mg/dL, and CO(2)-DSA was used preferentially and supplemented with ICA, when necessary. The two groups were compared for the outcomes of successful graft placement, renal function, endoleak type, and frequency, and the need for graft revision. Comparisons were made using chi(2) analysis, Student t test, and the Fisher exact test. RESULTS: A total of 84 EVARs were performed in group I and 16 in group II. Patient demographics and risk factors were similar between groups with the exception of serum creatinine, which was significantly increased in group II (1.8 mg/dL vs 1.0 mg/dL P < .0005). All 100 endografts were successfully implanted. Patients in group II had longer fluoroscopy times, longer operative times, and increased radiation exposure, and 13 of 16 patients required supplemental ICA. Mean iodinated contrast use was 27 mL for group II vs 148 mL in group I (P < .0005). Mean postoperative serum creatinine was unchanged from baseline, and 30-day morbidity was similar for both groups. No patient required dialysis. No patients died. Perioperatively, and at 1 and 6 months, the endoleak type and incidence and need for endograft revision was no different between groups. CONCLUSIONS: CO(2)-DSA is safe, can be used to guide EVAR, and provides outcomes similar to ICA-guided EVAR. CO2-DSA protects renal function in the azotemic patient by lessening the need for iodinated contrast and associated nephrotoxicity, but with the tradeoff of longer fluoroscopy and operating room times and increased radiation exposure.  (+info)

Timing of initiation of dialysis in critically ill patients with acute kidney injury. (5/22)

Among critically ill patients, acute kidney injury (AKI) is a relatively common complication that is associated with an increased risk for death and other complications. To date, no treatment has been developed to prevent or attenuate established AKI. Dialysis often is required, but the optimal timing of initiation of dialysis is unknown. Data from the Program to Improve Care in Acute Renal Disease (PICARD), a multicenter observational study of AKI, were analyzed. Among 243 patients who did not have chronic kidney disease and who required dialysis for severe AKI, we examined the risk for death within 60 d from the diagnosis of AKI by the blood urea nitrogen (BUN) concentration at the start of dialysis (BUN < or = 76 mg/dl in the low degree of azotemia group [n = 122] versus BUN > 76 mg/dl in the high degree of azotemia group [n = 121]). Standard Kaplan-Meier product limit estimates, proportional hazards (Cox) regression methods, and a propensity score approach were used to account for selection effects. Crude survival rates were slightly lower for patients who started dialysis at higher BUN concentrations, despite a lesser burden of organ system failure. Adjusted for age, hepatic failure, sepsis, thrombocytopenia, and serum creatinine and stratified by site and initial dialysis modality, the relative risk for death that was associated with initiation of dialysis at a higher BUN was 1.85 (95% confidence interval 1.16 to 2.96). Further adjustment for the propensity score did not materially alter the association (relative risk 1.97; 95% confidence interval 1.21 to 3.20). Among critically ill patients with AKI, initiation of dialysis at higher BUN concentrations was associated with an increased risk for death. Although the results could reflect residual confounding by severity of illness, they provide a rationale for prospective testing of alternative dialysis initiation strategies in critically ill patients with severe AKI.  (+info)

Sensitivity and specificity of a single emergency department measurement of urinary neutrophil gelatinase-associated lipocalin for diagnosing acute kidney injury. (6/22)

BACKGROUND: A single serum creatinine measurement cannot distinguish acute kidney injury from chronic kidney disease or prerenal azotemia. OBJECTIVE: To test the sensitivity and specificity of a single measurement of urinary neutrophil gelatinase-associated lipocalin (NGAL) and other urinary proteins to detect acute kidney injury in a spectrum of patients. DESIGN: Prospective cohort study. SETTING: Emergency department of Columbia University Medical Center, New York, New York. PARTICIPANTS: 635 patients admitted to the hospital with acute kidney injury, prerenal azotemia, chronic kidney disease, or normal kidney function. MEASUREMENTS: Diagnosis of acute kidney injury was based on the RIFLE (risk, injury, failure, loss, and end-stage) criteria and assigned by researchers who were blinded to experimental measurements. Urinary NGAL was measured by immunoblot, N-acetyl-beta-d-glucosaminidase (NAG) by enzyme measurement, alpha1-microglobulin and alpha(1)-acid glycoprotein by immunonephelometry, and serum creatinine by Jaffe kinetic reaction. Experimental measurements were not available to treating physicians. RESULTS: Patients with acute kidney injury had a significantly elevated mean urinary NGAL level compared with the other kidney function groups (416 microg/g creatinine [SD, 387]; P = 0.001). At a cutoff value of 130 microg/g creatinine, sensitivity and specificity of NGAL for detecting acute injury were 0.900 (95% CI, 0.73 to 0.98) and 0.995 (CI, 0.990 to 1.00), respectively, and positive and negative likelihood ratios were 181.5 (CI, 58.33 to 564.71) and 0.10 (CI, 0.03 to 0.29); these values were superior to those for NAG, alpha1-microglobulin, alpha1-acid glycoprotein, fractional excretion of sodium, and serum creatinine. In multiple logistic regression, urinary NGAL level was highly predictive of clinical outcomes, including nephrology consultation, dialysis, and admission to the intensive care unit (odds ratio, 24.71 [CI, 7.69 to 79.42]). LIMITATIONS: All patients came from a single center. Few kidney biopsies were performed. CONCLUSION: A single measurement of urinary NGAL helps to distinguish acute injury from normal function, prerenal azotemia, and chronic kidney disease and predicts poor inpatient outcomes.  (+info)

Impact of renal failure on survival of African patients with cirrhosis. (7/22)

To assess the effect of renal failure on the survival of black African patients with cirrhosis, we studied 132 (82 males, 50 females) cirrhotic black African patients with mean age of 47.5+/-14.4 years and mean follow-up period of 373+/-194 days. The edema and ascitis were the main reasons for admission to hospital. Renal failure was present in 30 (22.7%) patients, and it was positively correlated to the severity of the stage of the liver disease, and associated with severe hyponatremia. Survival at 1 year was 60.1% and 37.6% in the absence or presence of renal failure, respectively (p<0.001)). The stage of the liver disease was significantly inversely correlated with survival, which was further diminished in the presence of renal failure:23.7% versus 12.5% for Child-Pugh-Turcote (CPT) A-B in the absence or presence of renal failure, respectively (p=0.67), 30.2% versus 81.8% for CPT C in the absence or the presence of renal failure respectively (p<0.001). Hyponatremia has also appeared detrimental to survival, since mortality was 38.4% versus 81.8% in the absence or the presence of hyponatremia respectively (p<0.001). By multivariate analysis, renal failure, CPT stage C, and hyponatremia independently significantly correlated to mortality in patients with cirrhosis. We conclude that renal failure is frequently associated with decompensated cirrhosis. The presence of renal failure in this setting often results in high mortality. Renal failure that occurs in the setting of a severe liver disease and hyponatremia may be part of hepatorenal syndrome.  (+info)

Uremia induces proximal tubular cytoresistance and heme oxygenase-1 expression in the absence of acute kidney injury. (8/22)

 (+info)

Prerenal azotemia is common, especially in older adults and in people who are in the hospital.. The kidneys filter the blood. They also make urine to remove waste products. When the amount, or pressure, of blood flow through the kidney drops, filtering of the blood also drops. Or it may not occur at all. Waste products stay in the blood. Little or no urine is made, even though the kidney itself is working.. When nitrogen waste products, such as creatinine and urea, build up in the body, the condition is called azotemia. These waste products act as poisons when they build up. They damage tissues and reduce the ability of the organs to function.. Prerenal azotemia is the most common form of kidney failure in hospitalized people. Any condition that reduces blood flow to the kidney may cause it, including ...

N2 - Thirty-three hypertensive patients with a wide range of renal function were studied during initiation of angiotensin-converting enzyme inhibition with captopril to evaluate changes in potassium levels concomitant with reduction of aldosterone excretion. Ten patients (Group I) with low levels of plasma renin activity had no change in either aldosterone excretion or potassium during the first week of therapy. Twenty-three other patients (Group II) had decreased aldosterone excretion of an average of 63 percent, often reversing secondary hyperaldosteronism. This was associated with a rise in serum potassium from 3.6 ± 0.1 to 4.4 ± 0.1 mEq/liter (p , 0.001). Serum potassium levels during captopril therapy were inversely related to ...
The terms uremia and azotemia are applied to acute or chronic conditions in which the blood concentration of nitrogenous end products rises. The terms are otherwise poorly defined. Nitrogen retention usually occurs when the renal function is less than 30% of normal. Recently, progressive renal dysfunction has been graded as [1] diminished renal reserve, [2] renal insufficiency, [3] renal failure, and [4] uremia (Strauss and Welt (1) 1963), but each grade overlaps others.. Although urea is present in greatest amount, errors can occur when increased urea concentration is accepted as synonymous with the degree of renal dysfunction. Myers, Fine, and ...
Azotemia (azot, "nitrogen" + -emia, "blood condition") is a medical condition characterized by abnormally high levels of nitrogen-containing compounds (such as urea, creatinine, various body waste compounds, and other nitrogen-rich compounds) in the blood. It is largely related to insufficient or dysfunctional filtering of blood by the kidneys. It can lead to uremia and acute kidney injury (kidney failure) if not controlled.

Someone suffering from azotemia may find that their output of urine is significantly reduced, leading to an increased risk of that person developing urinary tract infections and other similar problems. Its always a worrying sign when the body loses its regularity, as it can be indicative of a wide range of underlying issues. The best thing to do if you find that you are outputting less urine than you normally would is to consult a doctor or a medical professional for advice, however, it would also be a good idea to try and drink some water to make sure that youre not just a little dehydrated. People can sometimes tend to get a little squeamish when it comes to talking about going to the bathroom, and thats just silly because its something we all have to do whether we like it or not. Talking about it means problems can be shared and solved with more ease.. ...

The glomerular injury of preeclampsia manifests as a clinical triad, namely, hypertension, albuminuria, and a loss of intrinsic filtration capacity that lowers the GFR. Although we estimate that filtration capacity, as approximated by an ultrafiltration coefficient (Kf), is depressed by ,50% at the end of pregnancy (postpartum day 1, Table 3), this phenomenon is not widely recognized by clinicians. This is because GFR depression in clinical practice is identified by the presence of azotemia. The absence of overt azotemia (usually defined in women as serum creatinine ,1.2 mg/dl) in preeclamptic mothers during postpartum weeks 1 and 2 obscured the extent to which GFR and computed Kf were depressed in these subjects compared with healthy gravid control subjects.. We examined glomerular structure and ultrastructure in those subjects of the present report who were studied on day 1. We undertook a morphometric analysis of transmission and scanning electron photomicrographs (13). We showed that reduced ...

Patients treated with the calcineurin inhibitorsandare at high risk of developing renal injury. Calcineurin inhibitor nephrotoxicity (CIN) is manifested either as acute azotemia, which is largely reversible after reducing the dose, or as chronic prog
The purpose of this study was to evaluate the disposition kinetics of digoxin after the administration of a single intravenous dose to the same dogs before and during azotemia. The digoxin plasma concentration-time data were fitted to a multicompartment model using nonlinear regression analysis. During azotemia, the biological half-life of digoxin was prolonged in six of seven dogs, while digoxin renal clearance, body clearance and apparent volume of distribution were significantly decreased. There was a corresponding increase in the apparent volume of the "central" compartment of digoxin. Approximately 45% of a digoxin dose was excreted by the kidney in these animals indicating a substantial nonrenal component to digoxin elimination in the dog. This nonrenal elimination did not change during azotemia, despite a decrease in renal clearance by 61%. ...
252 It is evident that blood sulfonamide levels above 8 mg. per 100 cc. were observed only in patients suffering from oliguria, or high azotemia, or both. Attempts at closer analysis are disappointingly inconclusive. The average blood sulfonamide level in 36 azotemic patients was 5.7 mg. per 100 cc. as compared with 2.3 mg. per 100 cc. in the control group of 14, but again the variations are too wide in proportion to the number of samples to warrant statistical analysis. The mean blood sulfonamide level in 38 oliguric patients was 5.4 and in 12 without oliguria, 2.5 milligrams per 100 cubic centimeters. The results are similar when the cases are divided, in an attempt to exclude the influence of variation in dosage, into two groups as follows: Group A, those patients who had external medication only, and Group B, those who received internal medication (oral, intraperitoneal, or intravenous). Eight patients could not be classified because of inadequate information regarding therapy. Of the 18 ...

Other nonspecific laboratory abnormalities commonly found in patients with hypercalcemia result from disordered renal function. Patients commonly have significant azotemia at presentation.
PURPOSE We evaluated the role of surgery for genitourinary tuberculosis with special emphasis on reconstructive procedures. MATERIALS AND METHODS Case records of 241 patients with genitourinary tuberculosis who underwent surgery at our center during a period of 17 years were reviewed. Clinical features, organ involvement, investigations, treatment and outcome of therapy were studied. RESULTS There were 129 males and 112 females with a mean age of 34.6 years. The most common presentation was irritative voiding symptoms. Azotemia was seen in 54 (22.4%) cases. The most commonly involved organ was the kidney in 130 (53.94%) cases. Preoperative bacteriologic diagnosis was confirmed in 70 (29%) cases. All patients received antitubercular drug therapy for 9 months. A total of 248 procedures, including 33 endoscopic, 87 ablative and 128 reconstructive, were performed with some patients requiring more than 1 procedure. Early complications, which mainly involved the bowel, were seen in 19 (7.88%) cases.
A prospective study of 213 patients admitted to a medical intensive care unit was done to determine the frequency of colonization of the respiratory tract with Gram-negative bacilli and the relation of such colonization to nosocomial infection. Ninety-five patients (45%) became colonized, 22% on the first hospital day. Associated with colonization were respiratory tract disease, coma, hypotension, tracheal intubation, acidosis, azotemia, and either leukocytosis or leukopenia. Antimicrobial therapy may have promoted colonization in some patients. Nosocomial infections developed in 26 patients (12.2%), 22 of whom were colonized with Gram-negative bacilli. Nosocomial respiratory infections occurred in 23% of colonized patients but in only 3.3% of noncolonized patients. The control of nosocomial pneumonia may require the development of methods for preventing or interrupting the colonization of hospitalized patients with Gram-negative bacilli. ...
Case Description We present the case of a 16 year-old female, previously well, who presented to her community hospital with a 9-day history of fever and pharyngitis. Her symptoms progressed (despite oral antibiotics) to include malaise, abdominal pain, and eventually shortness of breath, pleurisy, and profound nausea, prompting her to seek medical attention. Upon assessment the patient was hypotensive and tachypneic with mild respiratory distress; she was in gallop rhythm and had a very tender abdomen. Her laboratory investigations revealed a slightly elevated white cell count with left shift, thrombocytopenia (platelet count 59,000), azotemia, elevated bilirubin, and metabolic acidosis. She was transported to our pediatric intensive care unit and electively intubated and ventilated. Despite broad-spectrum antibiotics and inotropic support, the patients course was complicated by persistent fever and coagulopathy. Numerous other investigations, including head and abdominal imaging, revealed no ...

The first condition for BUN increasing is renal dysfunction caused by Acute Nephritis, Chronic Nephritis, Toxic Nephritis, serious pyelonephritis, Renal Tuberculosis, renal vascular sclerosis, congenital PKD and renal tumors. BUN increasing has an important role in diagnosing Uremia. The level of BUN increasing is consistent with the serious condition of disease. For example, at the stage of azotemia, BUN is above 9mmo/l, but at the stage of Uremia BUN can be more than 20mmol/l. So BUN increasing can help to evaluate which stage the diseases condition has developed into ...
The relationship of natriuretic effect and furosemide excretion was studied in normal and azotemic dogs. Graded azotemia was produced in dogs by bilateral uretero-venous shunts of varying duration. The shunts were subsequently opened and urine and blood samples were taken to measure inulin, furosemide and sodium concentrations. Renal blood flow was measured by an electromagnetic flow probe. Two groups of dogs, control and experimental, were studied. The experimental group received a loading dose followed by a constant infusion of furosemide. This dose produced a natriuresis in nonazotemic normal dogs. The magnitude of this natriuresis correlated with furosemide excretion rate (P less than .005) and not with the plasma concentration of the drug. Furosemide clearance and extraction were inversely correlated with blood urea nitrogen. In the furosemide-treated group the augmentation of sodium excretion was not impaired except at blood urea nitrogen concentrations of greater than 200 mg/dl (two ...
Background and purpose: Breastfeeding is the best method of nutrition for infants and would lead to better somatic growth and neurologic development. It is an effective factor in decreasing infant morbidity and mortality. Inadequate breastfeeding results in complications such as failure to thrive, dehydration, uremia, azotemia and hypernatremia. The aim ...
Hypotension: Epaned can cause symptomatic hypotension, sometimes complicated by oliguria, progressive azotemia, acute renal failure, or death. Patients at risk of excessive hypotension include those with the following conditions or characteristics: heart failure with systolic blood pressure below 100 mmHg, ischemic heart disease, cerebrovascular disease, hyponatremia, high-dose diuretic therapy, renal dialysis, or severe volume and/or salt depletion of any etiology. These patients should be started under close medical supervision and closely followed for the first 2 weeks of treatment with Epaned and whenever the dose of Epaned and/or a diuretic is increased. Symptomatic hypotension is also possible in patients with severe aortic stenosis or hypertrophic cardiomyopathy. ...

An excess level of nitrogen-based substances compounds such as urea, creatinine, and other body waste compounds in the blood is defined as azotemia. It can be caused by higher than normal production of nitrogen-containing substances (with high protein diet or gastrointestinal bleeding), improper filtration in the kidneys (kidney disease), or reabsorption of urine back to bloodstream.
e volume of fluid therapy is only indicated for the presence of this indicator.To calculate the required infusion volume summarize the "visible" and "invisible" fluid loss."Invisible" losses represent the amount of water extracted through the skin and lungs during quiet breathing.Normally, these losses amount to 500-600 ml / day.Consequently, for anuria as "visible loss" absent daily amount of fluid injected should not exceed 500-600 ml.. 3.

After we process and analyze a cat bloodwork sample, the next step is to help our patients human caretaker fully understand any abnormal results. Your cats blood work allows our veterinarians to evaluate the following:. This is a serum protein that helps evaluate hydration, hemorrhage and intestinal, liver and kidney disease.. Elevations in this test may indicate liver damage, Cushings disease or active bone growth in a young cat. This test is especially significant in cats.. This test may determine active liver damage, but does not indicate the cause.. Elevations in this test indicate pancreatitis or kidney disease.. Increases in this test may indicate liver, heart or skeletal muscle damage.. This test determines kidney function. An increased level is called azotemia and can be caused by kidney, liver and heart disease as well as urethral obstruction, shock or dehydration.. Changes in the normal level of this test can indicate a variety of diseases. Tumors, hyperparathyroidism, kidney ...
Therapeutic measures included the elimination of fluoride from the drinking water, normalization of plasma calcium and phosphate concentrations, and the use of vitamin D analogs. Symptoms were lessened with these measures, but several patients continued to have fractures. Four patients have been free of symptoms or fractures since entering the dialysis program using fluoride-free dialysate and continuing efforts to maintain normal calcium and phosphate levels.. Case of Severest Disease. A 69-year-old man experienced excessive frequent urge to urinate associated with pyuria in 1958. Signs of infection cleared after sulfonamide therapy, but urinary frequency, nocturia, and polyuria persisted. The urine was of fixed specific gravity and showed a trace of protein. Mild azotemia appeared in 1960, followed by bone pain, arthralgia of the knees and feet, and spontaneous "march fractures" of both feet - a total of 13 by 1963.. Examination of the urine revealed no infection, but a 24-hour specimen showed ...

Ultimately, prerenal ARF is caused by sustained hypotension that reduces renal perfusion. However, many of the etiologies discussed below reduce renal perfusion over courses much longer than hours to days. Given the relatively slow decline in renal perfusion, how can these etiologies precipitate relatively sudden drops in GFR? The answer is that neuroendocrine and autoregulatory mechanisms can usually maintain GFR in the face of falling renal perfusion over a wide range. However, at some point these mechanisms cannot sufficiently compensate and this precipitates a sudden drop in GFR, manifesting as ARF ...

A 15-year-old castrated male domestic shorthair cat presented for evaluation of polyuria/polydipsia and weight loss despite a good appetite. He weighed 9 pounds (4.1 kg) with a body condition score of 4/9. Moderate atrophy of the epaxial muscles was noted. Physical examination was otherwise unremarkable. A CBC revealed a mild, non-regenerative anemia (Hct, 25%; reference range, 31-46%).The biochemistry profile revealed hyperglycemia (glucose, 583 mg/dl; reference range, 70-120 mg/dl) and azotemia (BUN, 99 mg/dl; reference range, 15-33 mg/dl; creatinine, 3.2 mg/dl; reference range, 0.9-2.1 mg/dl). Urinalysis revealed a specific gravity of 1.015 with 4+ glucose and no proteinuria. T4 was within the reference range. A complete diet history revealed that the cat was eating ½ cup over-the-counter (OTC) dry adult maintenance cat food plus two 3 oz. cans of cat food per day (both made by good quality major manufacturers - specific varieties and flavors were included in the diet history). The cat did ...
Urinary sodium levels less than 10 mmol/L are associated with extra-renal sodium loss (GI or sweat), pre-renal azotemia, severe volume depletion, and edematous states. Levels greater than 10 mmol/L are seen in acute tubular necrosis, SIADH, Addisons disease, and renal salt wasting ...

Bad news on the health front- At that same doctors appointment on 11/1 he was talking to me about my bp and he mentioned that I am on A LOT of medication, which I think I am too. I told him that I kinda feel like it might not even be enough because Ill have days when it gets pretty high (130-140/90s). He asked me if I had ever had my kidneys checked and I said that all of my bloodwork has come back with normal kidney function. He decided to refer me to a specialist anyway and wanted me to have an ultrasound done on all of my "systems" so I went in on 11/8. I figured all theyd find was a gallstone (they found one when I was pregnant with Gracie) but when I turned to see the screen as she was checking my left kidney I saw a black blip on the screen. I asked "Is that a cyst?" and she said yes very nonchalantly. I know they arent supposed to discuss their findings with the patients so I didnt press her for more ...
Acute kidney injury (AKI) is an important cause of death among hospitalized patients. The 2 most common causes of AKI are acute tubular necrosis (ATN) and prerenal azotemia (PRA). Appropriate diagnosis of the disease is important but often difficult. We analyzed urine proteins by 2-dimensional gel electrophoresis from 38 patients with AKI. Patients were randomly assigned to a training set, an internal test set, or an external validation set. Spot abundances were analyzed by artificial neural networks to identify biomarkers that differentiate between ATN and PRA. When the trained neural network algorithm was tested against the training data, it identified the diagnosis for 16 of 18 patients in the training set and all 10 patients in the internal test set. The accuracy was validated in the novel external set of patients where conditions of 9 of 10 patients were correctly diagnosed including 5 of 5 with ATN and 4 of 5 with PRA. Plasma retinol-binding protein was identified in 1 spot and a fragment ...
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 ...
United States. POLYCYSTIC RENAL DISEASE. The clinical significance of polycystic renal disease depends on whether it is unilateral or bilateral and the amount of associated renal parenchymal damage. Congenital polycystic renal disease has been reported in related long-haired kittens of both sexes. Acquired polycystic renal disease has been described in male and female cats three to eight years of age. It is inherited as an autosomal dominant trait in the Persian cat. Renal cysts can be detected by ultrasonography as early as six to eight weeks of age, but renal failure does not occur until later in life. If chronic renal failure is present, compatible clinical signs are observed, including polyuria, polydipsia, anorexia, weight loss, and lethargy. On physical examination, enlarged irregular kidneys may be palpated, often accompanied by dehydration, pallor of mucous membranes, and emaciation. Laboratory findings include azotemia, hyperphosphatemia, isosthenuria, nonregenerative anemia, and ...
Urethrostomy is a surgical procedure that creates a permanent opening in the urethra, commonly to remove obstructions to urine flow. The procedure is most often performed in male cats, where the opening is made in the perineum. For many years perineal urethrostomy has been used in cattle, sheep and goats, especially young males that have been castrated at a young age, for obstruction by uroliths. However, the anatomy of the male cat is quite different and the urethra is very small in diameter. Perineal urethrostomy in the male cat was developed in 1962 and published in the Journal of the American Veterinary Medical Association in 1963. It was modified in 1967, and further modified in 1971. Since animals are potentially suffering from severe metabolic derangements at the time of initial presentation, animals need to be stabilized prior to surgery. Common physiologic derangements noted on bloodwork are elevated kidneys values (azotemia) and elevated potassium levels (hyperkalemia). The presence of ...
The Sign Test is a non-parametric alternative to the [[AP_Statistics_Curriculum_2007_Infer_2Means_Dep , One-Sample and Paired T-Test]]. The Sign Test has no requirements for the data to be Normally distributed. It assigns a positive (+) or negative (-) sign to each observation according to whether it is greater or less than some hypothesized value. It measures the difference between the ,math,\pm,/math, signs and how distinct the difference is from our expectations to observe by chance alone. For example, if there were no effects of developing acute renal failure on the outcome from sepsis, about half of the 16 studies above would be expected to have a relative risk less than 1.0 (a - sign) and the remaining 8 would be expected to have a relative risk greater than 1.0 (a + sign). In the actual data, 3 studies had - signs and the remaining 13 studies had + signs. Intuitively, this difference of 10 appears large to be simply due to random variation. If so, the effect of developing ...
Chronic pyelonephritis resulting from a mixed infection was produced in rats. They displayed marked hyposthenuria and azotemia and, on pathologic examination at the end of one year, revealed severe contraction and scarring of the kidneys. Hypertensive vascular disease did not develop even in rats with unilateral nephrectomy, although some animals succumbed to renal failure. The results indicate that parenchymal renal injury from chronic renal infection, even when it results from mixed infection and is associated with a decrease in renal mass, does not result in hypertensive disease. It is suggested that this is due to the absence of a vascular lesion producing renal ischemia.. ...
This study was designed to elucidate the expression of renal tissue cytokines by receiving concomitant ECMO and CRRT in the healthy swine model. Our results showed that it might remove ECMO-induced cytokines, maintain the role of immune equilibrium, reduce the extent of ECMO-related SIRS, thereby leading to improve ECMO-related acute renal dysfunction.. CRRT was applied to acute renal failure patients have been widely recognized. CRRT matched with human kidney by continuously, slowly and convection running. Its mainly advantage is that it could stabilize the hemodynamic, improve azotemia, electrolytes and water-salt metabolism, keep on cleaning cycle of all sorts of cytokines and improve nutrition [10-13].. Previous animal experiments and clinical studies have shown that blood components are continually exposed to non-biological artificial surface from cardiopulmonary bypass pipe and changes of the non-physiological hemorheology during ECMO running. This leads to the complement system, the ...
Ninety-six assessable patients with advanced or recurrent uterine sarcomas, who were no longer controllable with surgery and radiotherapy, and who had not received prior chemotherapy were treated with cisplatin 50 mg/m2 intravenously every 3 weeks. Of 63 cases with mixed mesodermal tumors, five complete responses (CRs; 8%) and seven partial responses (PRs; 11%) were observed (95% confidence interval [CI], 10.3% to 30.9%). Of 33 patients with leiomyosarcoma, one PR (3%) was observed (95% CI, .1% to 15.8%). Adverse effects included leukopenia (23%), nausea and vomiting (73%), and mild azotemia (42%). No patients experienced life-threatening toxicity. Cisplatin has definite activity when given at the dose and schedule that we tested for patients with mixed mesodermal sarcomas who have not received prior chemotherapy, but has little activity in patients with leiomyosarcoma ...
This case report describes the clinical, ultrasonographic and cystoscopic findings and treatment in a two-year-old Swiss Braunvieh heifer with rupture of a patent urachus. The lead signs in the seven-month-pregnant heifer were markedly abnormal general condition and demeanour and a pear-shaped abdomen. The heifer had severe azotaemia, and abdominal ultrasonography revealed ascites, which was diagnosed as uroperitoneum based on an elevated creatinine level in the fluid. A patent urachus was identified during cystoscopy; the endoscope could be advanced beyond the apex of the urinary bladder into the urachus. Based on all the findings, a diagnosis of uroperitoneum attributable to rupture of a patent urachus was made. The urachus was ligated twice via a left-flank laparotomy. The general condition normalised within a few days of surgery, and the patient calved normally and was in good health at follow-up evaluation. ...
Acute Renal Failure (ARF) ditandai dengan penurunan secara mendadak kadar filtrasi glomerular (GRF) dan alternasi kemampuan ginjal untuk mengeluarkan racun harian (Bagan 39-2). Kejadian ARF dapat berhubungan dengan penurunan produksi urin (oliguria, dengan produksi kurang dari 500 ml dalam waktu 24 jam), ataupun dengan aliran urin yang normal. Gangguan ini biasanya menyerang ginjal yang sebelumnya sehat/tidak terkena gangguan apapun. Durasinya berbeda-beda dari beberapa hari hingga beberapa pekan. Penyebab ARF sangat bermacam-macam, dan sering ada beberapa yang terjadi secara bergantian (Boks 39-1). Secara garis besar, penyebab terjadinya ARF dapat dikelompokkan menjadi tiga, yaitu: (1) kurangnya perfusi renal (prerenal), (2) penyakit yang terjadi pada parenkima renal (intrinsic), dan (3) obstruksi (postrenal). Biasanya, jika dilakukan pemeriksaan dengan diagnosis yang cermat saat terjadi prerenal dan obstruksi, ARF tidak akan berumur panjang dan tidak memerlukan intervensi nutrisi khusus ...

Home remedies for kidney stones symptoms are a miracle stock of alternative medicine which is the most natural way to kidney stones treatment. It also alleviates kidney pain naturally. With these remedies you can treat yourself in the most natural way. Results will be much more permanent than through any mainstream medicine. Using these home remedies for kidney stones symptoms will never give you any kind of side effects at all.. The condition forms solid crystals molded in the kidneys from the dietary minerals in the urine. Usually when the size of stones is small they normally pass out very easily through urination but when the size reaches 2-3 mm, it becomes very difficult for them to pass. This all results into lot of hindrance in the ureter and develops the chances of postrenal azotemia, hydronephrosis and spasm.. It all causes extreme pain in the flank, lower abdomen and groin along with vomiting, fever, nausea, sometimes blood from the urine along with painful urination. Pain is so severe ...
Equine Exertional Rhabdomyolysis is another fairly common disease seen that has a nutritional component in treatment and prevention. When I attended veterinary school in the 1970s it had several names, Monday Morning Disease, Azotemia, Myoglobinuria, Tying Up Syndrome, among others. It was typically seen in heavy muscled horses that were on a high plane of nutrition, and the treatment at the time was anti inflammatory medication, muscle relaxants, rest, fluid therapy, and decreasing the grain and concentrates in the ration. Forty years later, we have a new name for it, and a much better understanding of what causes it and why, but the treatment has not changed much. We now know that many of these horses have a genetic predisposition for this, and we have learned how to identify these horses through genetic testing, which until recently wasnt an option. What happens is that these horses have the ability to store large amounts of the polysaccharide "glycogen" in their muscle tissue, which when ...
We have projects in progress aimed at identifying putative modifier genes that predispose a subset of above patients to a more severe course of disease, compared to others who maintain a normal kidney function until late age. In doing this we take advantage of the patient cohorts that we classify as mildly or severely affected based on their clinical presentation. Among others we are interested in finding a putative role of miRNAs in normal function as well as in disease. Finally, we developed cell culture systems for investigating the role of collagen IV mutations on the synthesis and secretion of type IV collagen as well as their suspected role in the ER stress response through the activation of the Unfolded Protein Response signalling cascade. Our Center maintains collaborations with researchers and laboratories in Cyprus, Greece, Europe and the United States that have led to the mapping and cloning of new genes and in the investigation of pathological mechanisms at molecular and cellular ...

What kind of therapy do they need? They need medicines to repair the damaged cells and other therapy to provide new cells to replace the dead ones. In this way, they would have the chance to get a normal kidney function. If you are hoping to get this type of treatment, please try immunotherapy. It is a comprehensive treatment which supplies several effective therapies for patients to regain kidney function. For example, Micro-Chinese Medicine Osmotherapy can regulate immune system and block renal inflammation, so the damaged cells would be saved from the hurt of continuous inflammation. Furthermore, Immunotherapy is the only treatment recently for producing new cells for kidneys. So new blood vessels, nephrons and other tissues can be produced ...
GPs should act faster to manage acute kidney injury (AKI), NHS experts have said, as changes to IT systems this month allow practices to receive blood test warning alerts direct from pathology labs.

In the actual data, 3 studies had "-" signs and the remaining 13 studies had "+" signs. Intuitively, this difference of 10 appears large to be simply due to random variation. If so, the effect of developing acute renal failure would be significant on the outcome from sepsis. ...
TY - JOUR. T1 - Cisplatin nephrotoxicity as a model of chronic kidney disease. AU - Shi, Mingjun. AU - McMillan, Kathryn L.. AU - Wu, Junxia. AU - Gillings, Nancy. AU - Flores, Brianna. AU - Moe, Orson W. AU - Hu, Ming C. PY - 2018/6/1. Y1 - 2018/6/1. N2 - Cisplatin (CP)-induced nephrotoxicity is widely accepted as a model for acute kidney injury (AKI). Although cisplatin-induced chronic kidney disease (CKD) in rodent has been reported, the role of phosphate in the cisplatin-induced CKD progression is not described. In this study, we gave a single peritoneal injection of CP followed by high (2%) phosphate diet for 20 weeks. High dose CP (20 mg/Kg) led to high mortality; whereas a lower dose (10 mg/Kg) resulted in a full spectrum of AKI with tubular necrosis, azotemia, and 0% mortality 7 days after CP injection. After consuming a high phosphate diet, mice developed CKD characterized by low creatinine clearance, interstitial fibrosis, hyperphosphatemia, high plasma PTH and FGF23, low plasma ...
A kidney stone, also known as a renal calculus is a solid concretion or crystal aggregation formed in the kidneys from dietary minerals in the urine. Urinary stones are typically classified by their location in the kidney (nephrolithiasis), ureter (ureterolithiasis), or bladder (cystolithiasis), or by their chemical composition (calcium-containing, struvite, uric acid, or other compounds). Kidney stones typically leave the body by passage in the urine stream, and many stones are formed and passed without causing symptoms. If stones grow to sufficient size they can cause obstruction of the ureter. Ureteral obstruction causes postrenal azotemia and hydronephrosis (distension and dilation of the renal pelvis and calyces), as well as spasm of the ureter. - Stock Image C017/5014
The therapeutic effects of angiotensin converting enzyme inhibitor, lisinopril, on puromycin aminonucleoside (PAN)-induced nephrosis were investigated using unilaterally nephrectomized rats. Lisinopril showed potent dual effects on PAN nephrosis. Lisinopril treatment (50 mg/l in drinking water)from day 5 or day 9 reduced urinary protein excretion and suppressed the development of glomerular sclerosis at 8 weeks after PAN injection (150 mg/kg, i.p.), indicating a therapeutic effect on the nephrosis. Recovery of decreased anionic charge sites on the glomerular basement membrane was involved, at least in part, in the therapeutic action of lisinopril against proteinuria. On the other hand, oliguria and progressive azotemia derived from continuous deterioration of the renal function was induced if the treatment of lisinopril was started on the same day as PAN injection. The renal dysfunction induced by simultaneous administration of lisinopril with PAN could be abolished by combination dosing with ...
Conservative management consisting of a diet high in fiber and moisture content, stool softeners and intermittent evacuation of feces from the dilated/deviated rectum, may be tried but is not successful long-term. Surgical repair of the hernia is the treatment of choice. A number of herniorrhaphy techniques exist including traditional apposition of pelvic diaphragm structures, internal obturator muscle transposition, superficial gluteal muscle transposition, and the use of prosthetic or biomaterial implants such as polypropylene mesh or Porcine Small-Intestinal Submucosa. Currently internal obturator muscle transposition is the technique of choice of most surgeons in most cases. Prior to surgery, CBC, chemistry panel and urinalysis should be performed to assess the patients anesthetic status and look for concurrent illnesses. If the urinary bladder is involved, azotemia and metabolic changes may be noted. Urine culture should be considered in cases with concurrent cystitis. Enemas are not ...
We just had our 20 week anatomy scan today, and for the most part things looked good with the exception of some renal abnormalities. DH was born with whats called vesiculoureteral reflux and had to have surgery as a baby to reattach his ureters to his bladder. Based on todays scan, we think that may be whats going on with our first LO. She has dilated collecting systems, normal kidneys,, normal bladder, and normal amniotic fluid levels. We are being referred to the Pediatric Nephrologist (who DH and I both work with and adore), as well as a Pediatric Urologist (not even a part of our hospital). Well be getting ultrasounds every 4 weeks now, with both the MFM and Nephrologists there at those appointments. I feel like we have a plan, and Im only slightly having alarm bells go off. I hope this is what DH had - as DH has normal kidney function as an adult. Does anyone have any experience with kidney issues in particular, or with getting a vague diagnosis like this and having to increase ...
Blood tests showed normal kidney function. Because this was my third kidney infection I was given an ultrasound on my kidney to look for underlying causes, but this came back normal. (That said, the radiologist told me she could see no signs of infection on the ultrasound, so Im not entirely sure I trust anything she said as infection isnt something you would see on an ultrasound?!). Ive been told my ongoing abdominal pain is functional pain, but it also seems to increase when my flank pain increases, so Im not at all convinced ...
Metformin is an oral anti-diabetic drug from the biguanide class.

The development of the IVC involves fusion, regression, and establishment of midline anastomoses between parts of three paired fetal venous systems: the two posterior cardinal veins, the two subcardinal, and two supracardinal νeins. The changes in the abdominal venous systems that produce the final IVC cover a long period from day 25 to day 50, mainly between days 29 and 41. Depending on the embryonic origin, four parts of the IVC have been recognized: (1) hepatic segment, (2) prerenal segment, (3) renal segment and, (4) postrenal segment. "Absent IVC" normally designates absence of the prerenal segment of the IVC only, with azygos continuation being the most common variety of an interrupted IVC. "Full IVC agenesis" should cover those cases in which all four parts of the IVC and the iliac venous system are absent and blood return is accomplished by one or both of the following pathways: (1) vertebrolumbar pathway (anterior external vertebral plexus, ascending lumbar veins, and azygos and ...

If the serum phosphorus concentration is increased and kidney function is normal, hypervitaminosis D or bone osteolysis from metastatic or primary bone neoplasia are the primary differentials.. Determining whether kidney failure is primary or secondary to hypercalcemia caused by another disorder, when hyperphosphatemia and hypercalcemia coexist with azotemia, can be difficult. Measurement of serum ionized calcium concentration may help identify dogs and cats with renal failure-induced hypercalcemia. Serum ionized calcium concentrations are typically normal or decreased in renal failure and increased in hypercalcemia caused by other disorders.. Hypercalcemia of malignancy and primary hyperparathyroidism are the primary differentials when hypercalcemia and normal to low serum phosphorus concentrations are identified. The most common malignancy is lymphoma. A careful review of the history and physical examination findings may provide clues to the diagnosis. Systemic signs of illness suggest ...
Intravenous injection of Type 1 streptococcal M protein into mice and rats produced lesions confined to renal glomeruli. Thrombi of eosinophilic amorphous material, seen to occlude glomerular capillaries, were shown to contain M protein and fibrinogen. Gradual regression of the morphological lesions was observed during the 3 weeks following injection. Initial abnormal proteinuria and azotemia returned to control levels by the end of the 1st week; a second rise in urinary protein excretion and urea retention was demonstrated in some rats coincident with appearance of anti-M antibodies. The mechanism of renal localization of streptococcal M protein by means of a complex with fibrinogen was suggested, which may comprise an initial phase in the pathogenesis of acute poststreptococcal glomerulonephritis.. ...
Pauci-immune glomerulonephritis is a pattern of glomerulonephritis characterized by an absence of clear glomerular antibody deposits and usually occurs as a component of several ANCA-positive vasculitides such as Wegener Granulomatosis or microscopic polyangiitis. Although pauci-immune glomerulonephritis is not always present in those with Wegener Granulomatosis and microscopic polyangiitis, when it does occur, patients display signs and symptoms of nephritic syndrome (i.e. Hematuria, pyuria, secondary hypertension, oliguria, and azotemia ...
Results The CKD patients had higher diabetes mellitus (24.8% vs 43.5%, P = 0.01), anaemia (5.6% vs 16.1%, P = 0.03) and high on treatment platelet reactivity (28.6% vs 45.2%, P = 0.03) than those with normal kidney function patients. Logistic regression analyses showed that CKD and diabetes mellitus were independent predictors of HPR. Prevalence of HPR was higher in CKD patients compared with normal kidney function patients (65.1% ± 10.2 vs 45.3% ± 7.8, P , 0.01). In subgroup analysis testing was done before and after antiplatelet treatment. At baseline there were no differences in platelet aggregation, however, absolute decrease in reactivity after antiplatelet treatment was significantly less in CKD patients compared to patients with normal kidney function (63.2% ± 8.6 vs 43.2% ± 5.2, P , 0.01).. ...
In patients whose renal function may depend on the activity of the renin-angiotensin-aldosterone system (e.g., patients with severe congestive heart failure), treatment with angiotensin converting enzyme inhibitors has been associated with oliguria and/or progressive azotaemia and (rarely) with acute renal failure and/or death. Similar outcomes have been reported with losartan potassium. In studies of ACE inhibitors in patients with unilateral or bilateral renal artery stenosis, increases in serum creatinine or BUN have been reported. Similar effects have been reported with losartan potassium; in some patients, these effects were reversible upon discontinuation of therapy ...
Acute kidney injury is characterized by abrupt deterioration in kidney function, manifested by an increase in serum creatinine level with or without reduced urine output. The spectrum of injury ranges from mild to advanced, sometimes requiring renal replacement therapy. The diagnostic evaluation can be used to classify acute kidney injury as prerenal, intrinsic renal, or postrenal. The initial workup includes a patient history to identify the use of nephrotoxic medications or systemic illnesses that might cause poor renal perfusion or directly impair renal function. Physical examination should assess intravascular volume status and identify skin rashes indicative of systemic illness. The initial laboratory evaluation should include measurement of serum creatinine level, complete blood count, urinalysis, and fractional excretion of sodium. Ultrasonography of the kidneys should be performed in most patients, particularly in older men, to rule out obstruction. Management of acute kidney injury involves
Acute kidney injury (AKI) is a common condition with significant associated morbidity and mortality. Although impressive progress has been made in the understanding of the molecular and biochemical mechanisms of kidney injury, as well as in the clinical care of patients with AKI, outcomes have remained disturbingly static over the last 40-50 years. This new book presents topical research data in the study of the causes, diagnosis and treatment of acute kidney injury. Topics discussed include classification of AKI; acute renal failure in the newborn; kidney ischemia and reperfusion injury; pandemic H1N1 influenza A infection and AKI; the role of oxidative stress in renal ischemia; biomarkers in acute kidney injury and B2 adrenoceptor therapy in AKI.

BACKGROUND: Oxalate nephrosis is a highly prevalent disease in the Mount Lofty Ranges koala population in South Australia, but associated clinicopathologic findings remain undescribed. OBJECTIVES: The aims of this study were to determine plasma biochemical and urinalysis variables, particularly for renal function and urinary crystal morphology and composition, in koalas with oxalate nephrosis. METHODS: Blood and urine samples from Mount Lofty Ranges koalas with oxalate nephrosis were compared with those unaffected by renal oxalate crystal deposition from Mount Lofty and Kangaroo Island, South Australia and Moggill, Queensland. Plasma and urine biochemistry variables were analyzed using a Cobas Bio analyzer, and urinary oxalate by high-performance liquid chromatography. Urinary crystal composition was determined by infrared spectroscopy and energy dispersive X-ray analysis. RESULTS: Azotemia (urea , 6.6 mmol/L, creatinine , 150 μmol/L) was found in 93% of koalas with oxalate nephrosis (n = 15). ...
