Retreatment with interferon and ribavirin vs interferon alone according to viraemia in interferon responder-relapser hepatitis C patients: a prospective multicentre randomized controlled study.

Low pretreatment viral load has consistently been shown to be an independent predictor of sustained response (SR) in patients with chronic hepatitis C infection. We assessed the efficacy of interferon (IFN) plus ribavirin vs IFN alone in low viraemic patients (<2 millions copies/mL) who had relapsed to a previous course of IFN and the efficacy of 24 vs 48 week combination therapy in high viraemic patients. Two hundred and ninety-seven patients were randomly assigned to one of the four regimens after stratification on pretreatment viral load. All patients received IFN-alpha2b (6 million units thrice weekly for 24 weeks and 3 million units thrice weekly for 24 weeks). Patients with low viraemia received either IFN-alpha2b alone for 48 weeks (R1: 42 patients) or IFN-alpha2b plus ribavirin (600 mg/day) for 24 weeks and IFN-alpha2b alone for the next 24 weeks (R2: 48 patients). Patients with high viral load received either IFN-alpha2b plus ribavirin for 24 weeks and then IFN-alpha2b alone for the next 24 weeks (R3: 104 patients) or IFN-alpha2b plus ribavirin for 48 weeks (R4: 103 patients). In low viraemic patients the rate of SR was 37.7% in group R1 and 59.6% in group R2 (P < 0.05). In high viraemic patients, the rate of SR was 44.7% in group R3 and 51.4% in group R4 (P: NS). Thirty-one patients discontinued treatment (10.4%) without difference regarding treatment regimen. In the regimen using ribavirin we found no difference in terms of SR between patients receiving a dose of ribavirin below 10.6 mg/kg/day (55%) or over 10.6 mg/kg/day (58%). Histological improvement occurred in 70.2% of patients regardless of the regimen. Logistic regression showed that genotype 2 and 3, Knodell score <6 and alanine aminotransferase pretreatment level >3 x upper limit of normal were significantly and independently correlated with SR. In low viraemic patients who relapsed to a previous IFN treatment, combination therapy using high-dose IFN and low-dose ribavirin is better than high-dose IFN alone. In high viraemic patients there was no benefit in increasing the duration of combination therapy from 24 to 48 weeks. In this study, it was found that low dose of ribavirin can be used safely and there is no effect of ribavirin dose on SR.

Prevalence and risk factors of bacteriuria in cirrhotic patients: a prospective case-control multicenter study in 244 patients.

BACKGROUND/AIMS: The prevalence and risks factors of bacteriuria in cirrhotics have not been assessed by case-control study, and there are conflicting data concerning the role of liver failure and of ascites. The aims of this study were: i) to evaluate the prevalence of bacteriuria in cirrhotics, ii) to search for associated factors, iii) to evaluate the role of bladder post-void residual volume, and iv) to test the sensitivity of isolated bacteria to norfloxacin. METHODS: The prevalence and risk factors of bacteriuria on admission were determined by a multicenter prospective case-control study. RESULTS: Two hundred and forty-four cirrhotic patients and 240 controls were studied. Bacteriuria was present in 38 patients (15.6%; IC 5%: 11%-20%) and 18 controls (7.5%; IC 5%: 4.2%-11%; p<0.001). By univariate analysis, female sex and ongoing diuretic treatment were associated with bacteriuria (p<0.0001 and p<0.04, respectively). Pugh's grade, ascites and bladder residual volume were not associated with bacteriuria. By multivariate analysis, female sex (p<0.0001) and Child-Pugh score (p<0.03) were predictors of bacteriuria. Sensitivity of bacteria to norfloxacin was observed in 94.7%; sterile urine cultures were noted in 95.2% of patients treated with this antibiotic. CONCLUSION: Bacteriuria is twice as frequent in cirrhotic patients as in matched controls, and there is a trend to association with female sex and liver insufficiency.

[Prolonged clinical remission of cholangitis in early human immunodeficiency virus infection after surgical biliary derivation].

During the acquired immunodeficiency syndrome, most cases of cholangitis develop at an advanced stage of disease. We report a case of cholangitis in a 47-year-old homosexual man, stage IIa according to Center of Disease Control classification. An isolated jaundice was the first manifestation of the disease. The number of CD4 was 380/microL. Ultrasonography and endoscopic retrograde cholangiography showed a 7 cm stenosis of the common bile duct, and cystic duct stenosis, with associated intra-hepatic biliary duct dilatation. No infectious agent was found. Cholecystectomy and hepaticojejunostomy were performed. Pathological examination of liver biopsy and a sample of the resected common bile duct was consistent with sclerosing cholangitis. The postoperative course was uneventful. During a three year follow-up period, the patient was disease free but he suddenly died of uncontrolled bleeding from duodenal ulcer. In HIV-infected patients, surgical treatment can be performed in case of symptomatic long stenosis of the common bile duct.

Small intestinal stricture complicating superior mesenteric vein thrombosis. A study of three cases.

Mesenteric vein thrombosis associated with intestinal stricture, as a consequence of intestinal ischaemia, has only been mentioned twice in published works. The clinical, biological, and morphological aspects as well as the treatment of this morbid association were studied in three patients. In all, a two stage clinical course (initial acute abdominal pain and fever, followed by chronic intestinal obstruction), corresponding to the sequence thrombosis/stricture, was found. x Ray studies showed a regularly contoured intestinal stricture. Surgical resection was required in all three cases for stricture, associated in one case with mesenteric infarction. Anticoagulation treatment was used to preclude recurrence. Increased clinical awareness could lead to the diagnosis of intestinal stricture secondary to mesenteric vein thrombosis more often and at an earlier stage. Treatment consists of evaluation of predisposing features, intestinal resection when necessary, and anticoagulation therapy, as indicated.

[Post-radiation duodenal ulceration treated with hyperbaric oxygen].

Radiation enteric disorders are rare and difficult to treat. A case of radiation duodenitis treated by hyperbaric oxygen is reported. A sixty-year-old man underwent right nephroureterectomy, chemotherapy (platin and 5 fluorouracil) and radiation therapy (54 Gy) for excretory urinary carcinoma. Six months later, even though he was under omeprazole therapy for reflux oesophagitis, he experienced antroduodenitis, duodenal ulceration, and duodenal telangiectasia. Symptoms and duodenal ulcer disappeared 2 months later with hyperbaric oxygen (10 one hour sessions at 2 ATA). Most likely, hyperbaric oxygen can reduce the consequences of obliterative endarteritis due to irradiation, responsible for ischaemia and fibrosis later on.

[Autoimmune dysthyroidism induced by alpha interferon in two female patients with chronic non-A, non-B hepatitis].

We report two cases of autoimmune thyroid disorders which appeared after 6 months of recombinant alpha interferon therapy given for chronic non-A, non-B hepatitis. There was no family or personal history of thyroid disease, or had the patients taken any hepatic or thyroid toxic drugs. The other causes of hepatic and thyroid diseases were ruled out. The first case concerned a 33-year-old woman with sporadic hepatitis C. Therapy was complicated by the appearance of antimicrosomal thyroid antibodies and hypothyroidism. At 22 months, substitutive therapy was still necessary in one case. The second case involved a 37-year-old woman with post-transfusional non-A, non-B hepatitis which was complicated by transient hypothyroidism preceding thyrotoxicosis (with TSH-receptor antibodies). We observed a return to euthyroidism and loss of associated antibodies after withdrawal of interferon and institution of hormonal therapy.

[Digestive lymphomatous polyposis].

We report 7 prospectively followed cases of lymphomatous polyposis of the gastrointestinal tract. They were characterized by multiple polypoid lesions affecting several segments of the gastrointestinal tract always involving the colon and the rectum. An ileocecal mass was present in 4 cases. Regional lymph node involvement was constant. Peripheral lymphadenopathy was frequent (5 cases out of 7), as was other extra-digestive extension to the bone marrow (4 cases out of 7) and cavum (3 cases out of 7). The histopathological aspect was that of a small cleaved cells (working formulation) or centrocytic (Kiel classification) non-Hodgkin's lymphoma. The peculiar morphology and phenotype of the tumoral B-lymphocytes suggest their possible follicle marginal zone origin. Lymphomatous polyposis bore a rapidly fatal prognosis in every case (mean survival 20 months). This study of seven patients together with the 20 well-documented cases of the literature confirms the existence of lymphomatous polyposis as a distinctive clinicopathological entity among gastrointestinal non-Hodgkin's lymphoma.
