The aims of this study were the following: 1) to estimate the prevalence of hepatitis C virus (HCV) antibody (anti-HCV) in a population-based survey of French residents not selected for risk factors; 2) to investigate the association between anti-HCV seropositivity, viremia, the infecting HCV genotype, and the alanine transaminase (ALT) level; and 3) to(More)
Except for increased serum alkaline phosphatase (AP) levels, the changes in liver function test (LFT) values during normal pregnancy have not been clearly established, mainly because most studies do not include matched controls. We therefore measured the serum values of routine liver tests including 5'-nucleotidase and total bile acids in 103 healthy(More)
BACKGROUND The guaiac faecal occult blood test (G-FOBT) is recommended as a screening test for colorectal cancer but its low sensitivity has prevented its use throughout the world. METHODS We compared the performances of the reference G-FOBT (non-rehydrated Hemoccult II test) and the immunochemical faecal occult blood test (I-FOBT) using different(More)
We investigated variations in sensitivity of an immunochemical (I-FOBT) and a guaiac (G-FOBT) faecal occult blood test according to type and location of lesions in an average-risk 50- to 74-year-old population. Screening for colorectal cancer by both non-rehydrated Haemoccult II G-FOBT and Magstream I-FOBT was proposed to a sample of 20 322 subjects. Of the(More)
OBJECTIVE:The diagnosis of acute pancreatitis during pregnancy is usually based on the association of upper abdominal pain, nausea or vomiting, and elevated serum amylase or lipase activities. The changes in these enzymatic activities have not been clearly established during normal pregnancy. The aim of this study was therefore to evaluate serum amylase and(More)
OBJECTIVE Serum levels of sex-hormone-binding globulin (SHBG) have been reported in the literature to increase with age in both sexes. We have investigated the variations in levels of androgens, insulin and IGF-I with age and have evaluated their putative roles to obtain a better understanding of the increase in SHBG. DESIGN Cross-sectional pilot study of(More)
We studied the usefulness of the recently designed Trak-C assay for the detection and quantification of the hepatitis C virus (HCV) core antigen (Ag) for the screening of HCV infection in 4,201 subjects selected from 74,150 consecutive volunteers undergoing routine medical checkups. Subjects were selected for screening because they had risk factors (group(More)
A simple method for the simultaneous analysis of normetanephrine, metanephrine and 3-methoxytyramine (both free and conjugated) in human urine by reversed-phase ion-pair high-performance liquid chromatography with electrochemical detection has been developed. Existing methods have been optimized for extraction by study of analytical parameters. The(More)
