Endogenous creatinine clearance was assessed by inulin in 91 simultaneous studies in 41 patients and proved an accurate measurement of glomerular filtration rate. For filtration rates <20 ml/min the creatinine clearance may slightly overestimate the glomerular filtration rate. Successive determinations of filtration rate by either method may vary by 20% even though the methods agree with each o...
BACKGROUND & AIMS Since acute hepatitis C virus (HCV) infection is often asymptomatic, it is difficult to examine the rate and determinants of spontaneous clearance. Consequently, these studies are subject to bias, which can potentially lead to biased rates of viral clearance and risk estimates. We evaluated determinants of spontaneous HCV clearance among HCV seroconverters identified in a uniq...
1. The apparent renal clearance of intravenously injected [14C]glycocholate and [3H]chenodeoxycholate-3-sulphate was estimated in 22 patients with cholestasis. The degree of protein binding of the isotopes in serum from these patients was determined. The effects of pharmacological agents, changes in urine flow rate and pH on renal clearance was studied. 2. The mean renal clearance of [14C]glyco...
