RESUMO
New factors that influence the viral response in HCV non-genotype 2/3 patients must be identified in order to optimize anti-HCV treatment. This multicenter prospective study evaluates the influence of HCV variability and pharmacological parameters on the virological response of these patients to pegylated interferon α2a (peg-IFN-α2a: 180 µg/week) and ribavirin (RBV; 800-1,200 mg/day) for 48 weeks. HCV subtypes were identified by sequencing the NS5B region. Serum RBV and peg-IFN-α2a concentrations were measured at weeks 4 and 12. The 115 patients (67 men; median age = 49, range 31-76) included 64 who had never been treated and 27 co-infected with HIV. The mean baseline HCV RNA was 6.30 ± 0.06 log IU/ml and the HCV genotypes were: G1 (n = 93) with 1a (n = 37) and 1b (n = 50), G4 (n = 20) and G5 (n = 2). Most patients (79/108; 73%) had an early virological response. Independent predictors of an early virological response were interferon naive patients (OR= 2.98, 95% CI: 1.15-7.72) and RBV of >2,200 ng/ml at week 12 (OR = 3.41, 95% CI: 1.31-8.90). Forty of 104 patients (38%) had a sustained virological response. The only independent predictors of a sustained virological response were subtype 1b (OR = 6.82, 95% CI: 1.7-26.8), and HCV RNA <15 IU/ml at week 12 (OR = 25, 95% CI: 6.4-97.6). Thus a serum RBV concentration of >2,200 ng/ml was associated with an early virological response and patients infected with HCV subtype 1b had a better chance of a sustained virological response than did those infected with subtype 1a.

OBJECTIVES: To describe the characteristics of in-patients with alcoholic liver disease in Hepatogastroenterology and to evaluate whether geographic location was a risk factor for cirrhosis. METHODS: A French, national, multicenter, prospective investigation was performed in the last quarter of 1997. To be included in the study, patients had to have drunk at least 50 g of alcohol per day for the past year or to have cirrhosis. RESULTS: Seventeen centers included 802 patients, 20% had histologically proven cirrhosis or probable cirrhosis. Thirty-five percent had undergone liver biopsy. Twenty five percent of these patients had cirrhosis without acute alcoholic hepatitis and 37% had cirrhosis with acute alcoholic hepatitis. After dividing France along a Bordeaux-Strasbourg axis, there was more histologically proven or probable cirrhosis in the North (46%) than in the South (36%) (P<0.005) while daily alcohol intake was greater the South (150 +/- 6 g) than in the North (129 +/- 4 g) (P<0.0001). When the six variables (age, sex, daily consumption of alcohol over the past 5 years, presence of hepatitis B surface antigen and antibodies to hepatitis C virus, total duration of alcohol abuse) were considered together in stepwise logistic regression analysis, geographic location changed the prediction of cirrhosis. The odds ratio for cirrhosis in patients living to the North of the Bordeaux-Strasbourg axis was 1.9 (95% confidence interval range 1.1-3.2) (P<0.02), suggesting the role of nutritional factors.

The authors report a case of multi-recurrent Ogilvie's syndrome during pregnancy, the post-partum period and a long time after deliver. Electromyographic and manometric studies excluded colonic inertia and disseminated gastrointestinal involvement. Total colectomy was performed after the 6th recurrence, resulting in complete cure of the patient.

A 50 year old man with a 5-year history of recurrent anal fistula was treated by abdominoperineal amputation of rectum for perianal colloid adenocarcinoma. Characters of this rare affection of debatable pathogenicity are described, based on a literature review of 82 similar cases. The findings illustrate the evocative nature of an induration or better still a mucoid discharge from a recurrent anal fistula, and the need for deep and repeated biopsies to establish diagnosis. Since the course remains for a long period at the local and regional levels the treatment of choice is abdomino-perineal amputation.
