Estimation of serum C-peptide (SCP) is used as a measure of endogenous insulin secretion in type 2 diabetes mellitus (T2DM). Urinary CPeptide (UCP) and urinary C-Peptide creatinine ratio (UCPCR) are non invasive, simple and easily reproducible tests which may be considered as an alternative for SCP. In our study we estimated fasting serum C-peptide, urinary C-peptide and UCPCR in Type 2 Diabete...

Chronic occult lead poisoning often develops ensuing occupational lead exposure. Early diagnosis of lead poisoning is critical for timely discontinuation of lead exposure and for prognosis. This study explored the value of urinary kidney injury molecule-1 (KIM-1) in diagnosing renal injury induced by lead at an early stage. We retrospectively analyzed 92 workers exposed to occupational lead and...

A 51-year-old woman with asymptomatic proteinuria and haematuria was admitted for a renal biopsy. Upon admission, her blood pressure was 118/68mmHg. Urinalysis revealed proteinuria 1þ, blood 2þ, but glucose-negative. A microscopic examination showed 0–1 white and 20–30 red blood cells per high power field. Laboratory investigations showed serum total protein 6.8 g/dl, albumin 4.3 g/dl, sodium 1...

1. The role of water balance in the hypokalaemia of rats with diabetes insipidus (DI rats) was studied. 2. After a 3-day balance study DI rats had a lower muscle potassium content, and plasma [K+], and the urinary excretion of potassium in response to oral KCl loading was reduced when compared to normal rats. The hypokalaemia was found to be associated with elevated concentrations of potassium ...

BACKGROUND Urinary neutrophil gelatinase-associated lipocalin (NGAL) is a novel, sensitive and specific biomarker that is rapidly released after kidney injury. It predicts acute kidney injury (AKI) in multiple clinical scenarios. We hypothesized that urinary NGAL can predict AKI after liver transplantation. METHODS Urine was collected in 92 patients undergoing liver transplantation (18 living...

BACKGROUND We recently reported that immunoreactivity of intrarenal angiotensinogen (AGT) is significantly increased in IgA nephropathy patients. Meanwhile, we have developed direct enzyme-linked immunosorbent assays to measure plasma and urinary AGT (UAGT) in humans. This study was performed to test the hypothesis that UAGT levels are increased in chronic glomerulonephritis patients. METHODS...

BACKGROUND Reduction of proteinuria and blood pressure (BP) with blockers of the renin-angiotensin system (RAS) impairs the progression of chronic kidney disease (CKD). The aldosterone antagonist spironolactone has an antiproteinuric effect, but its use is limited by side effects. The present study evaluated the short-term antiproteinuric effect and safety of the selective aldosterone antagonis...

Purpose: To investigate the dual effect of angiotensin blockade by irbesartan and enalapril on proteinuria in diabetic patients with azotemia. Methods: Patients with diabetes of > 5 years duration, proteinuria at a nephrotic level and serum creatinine > 1.5 mg/dL were enrolled in the study. Forty-five enrolled patients were divided into three groups, those receiving enalapril , irbesartan, or e...

AIM To evaluate whether the urinary creatinine concentration is a reliable reference value to standardise urinary solute excretion in a spot urine sample during the first week of life. METHODS Spontaneously voided urine specimens were obtained in 48 healthy, full term neonates, aged 1 to 6 days (median 2.4) and in 168 healthy older children with a median age of 1.5 years (range 1 month to 3 y...
