BACKGROUND/AIMS: The aim of this study was to increase virologic response rates by individualized treatment according to the early virologic response. METHODS: Serum HCV-RNA was frequently quantified in patients with chronic hepatitis C (n=270) treated with peginterferon alfa-2a (180 microg/week) and ribavirin (1000-1200 mg/day). After 6 weeks patients were classified as rapid (RVR), slow (SPR), flat (FPR), or null responders (NUR) and randomized within each viral kinetic class to continue therapy either with an individualized or standard regimen. Individualized therapy comprised peginterferon monotherapy (48 weeks) or shorter combination therapy (24 weeks) for RVR, triple therapy with histamine (1 mg/day) (48 weeks) or prolonged combination therapy (72 weeks) for SPR, triple therapy for FPR, and high-dose peginterferon (360 microg/week) plus ribavirin for NUR patients. RESULTS: Patients were categorized as RVR (n=171), SPR (n=65), FPR (n=10), or NUR (n=22). Overall end-of-treatment and sustained virologic response rates were 77 and 60% in the individualized and 77 and 66% in the standard treatment arm, respectively. Histamine in addition to peginterferon and ribavirin and high-dose peginterferon plus ribavirin did not improve virologic response rates in patients with FPR and NUR, respectively. CONCLUSIONS: An improvement in virologic efficacy was not achieved with the available individualized treatment options.
OBJECTIVE: Alcohol consumption may play a role in the development of obesity but the relationship between alcohol and weight is still unclear. The aim of our study was to assess the cross-sectional association of intakes of total alcohol and of specific alcoholic beverages (wine, beer and spirits) with waist-to-hip ratio (WHR) and body mass index (BMI) in a large sample of adults from all over France. DESIGN: Cross-sectional. SETTING: Participants were free-living healthy volunteers of the SU.VI.MAX study (an intervention study on the effects of antioxidant supplementation on chronic diseases). SUBJECTS: For 1481 women aged 35-60 years and 1210 men aged 45-60 years, intakes of total alcohol and specific alcoholic beverages were assessed by six 24-hour dietary records. BMI and WHR were measured during a clinical examination the year after. RESULTS: A J-shaped relationship was found between total alcohol consumption and WHR in both sexes and between total alcohol consumption and BMI in men only (P<0.05). The same relationships were observed with wine (P<0.05); men and women consuming less than 100 g day(-1) had a lower BMI (men only) and WHR than non-drinkers or those consuming more. Spirits consumption was positively associated with BMI (linear regression coefficient beta=0.21, 95% confidence interval (CI): 0.09-0.34 and beta=0.22, 95% CI: 0.06-0.39 for men and women, respectively) and WHR (beta=0.003, 95% CI: 0.001-0.005 and beta=0.003, 95%CI: 0.0002-0.006) in both sexes in a linear fashion. No relationship between beer consumption and BMI or WHR was found. CONCLUSION: If confirmed in longitudinal studies, our results indicate that consumption of alcoholic beverages may be a risk factor for obesity.
In October of 2000, a second BSE crisis caught French public authorities unprepared and caused a collapse in beef consumption as well as considerable political turmoil. Data collected between May and July, 2000, among a group of general practitioners (GPs), while national consumption of beef was back to pre-BSE levels, paradoxically showed high latent risk perception, suggesting a new crisis was possible or likely.
