Efficacy of infliximab in Crohn's disease. Results of a retrospective multicenter study with a 15-month follow-up.

OBJECTIVES: To evaluate prescription practices and response to infliximab treatment for Crohn's disease (CD). PATIENTS AND METHODS: The files of CD patients treated with at least one infusion of infliximab treated in gastroenterology units belonging to university teaching hospitals of the Parisian hospitals group (Assistance Publique-Hôpitaux de Paris (AP-HP) during the year 2000 were analyzed retrospectively. RESULTS: One hundred and thirty-seven patients (36.0 +/- 12.7 years, 92 females) from 12 centers were studied. Indication for treatment was fistulae or perianal disease in 39% of patients, active Crohn's disease in 45% and mixed conditions in 16%. Mean follow-up was 15.2 +/- 7.2 months. The overall response rate was 85%. No predictive factor of sustained remission could be identified. The mean time to relapse was to 3.9 +/- 3.1 months. Thirty-eight patients were on maintenance therapy at the end of the follow up; 37% exhibiting progressive lost of response to treatment. Immunosuppressive therapy was added to infliximab in 78% of cases but response to infliximab was not modified by addition of immunosuppressive drugs. Adverse events, most frequently minor, were noted in 23% of the patients. CONCLUSION: This retrospective study confirms the efficacy and safety of infliximab in CD.

Prevalence and predictive factors of non-alcoholic steatohepatitis (NASH) in morbidly obese patients undergoing bariatric surgery.

BACKGROUND: In patients with morbid obesity selected for bariatric surgery, previous studies have shown a prevalence of NASH varying from 2.6% to 91%. The prevalence of NASH and extensive fibrosis were studied in a prospective cohort of patients with morbid obesity requiring bariatric surgery, to identify predictive factors of NASH. METHODS: From July 01 to Sept 02, every patient requiring bariatric surgery had a liver biopsy. The diagnosis of NASH was established using Lee's criteria. RESULTS: 92 patients (85 women, age 38 +/- SEM 11 years) were analyzed. Mean BMI was 45.7 +/- 5.1 kg/m2. 35 patients had lobular inflammation. 9 patients had steatosis associated with lobular necrotic and inflammatory foci and ballooning degeneration or pericellular fibrosis. No cirrhosis or extensive fibrosis was evidenced. The prevalence of NASH in this population was 9.8%. Waist/hips ratio and BMI were independent predictors of lobular inflammation, but only BMI was an independent factor of NASH in multivariate analysis. CONCLUSION: In this prospective cohort of patients at bariatric surgery, the prevalence of NASH was 9.8%. BMI was the only predictive factor for NASH.

Sugar intolerance: origin and mechanisms of symptoms?

The origin and mechanisms of symptoms in sugar intolerance were studied in 8 healthy volunteers. For two test periods, volunteers swallowed a probe with perfused catheters and an infusion catheter which migrated into the colon. A meal containing 40 g lactulose or 40 g sucrose was ingested; the sucrose meal was followed by colonic infusion of 40 g lactulose in order to bypass the small intestine. Recordings of small intestinal and colonic motility were performed. Abdominal pain, bloating, borborygmi, and flatulence were similar during both periods. Both meals increased small intestinal and colonic motility. Only 37% of the symptoms coincided in time with colonic motor events. Symptoms were not related to a specific motor event and were not correlated with breath hydrogen excretion. In conclusion, symptoms of sugar intolerance originate from the colon. They are not related to specific phasic motor events or to breath hydrogen excretion.
