[Mycobacterium kansasii infection in patients with human immunodeficiency virus infection].

We report a retrospective study of 12 caucasian men infected with HIV who had developed Mycobacterium kansasii infection (Mk). All patients had a low blood lymphocyte CD4 count (1-130, mean 15/mm3) and ten met the diagnostic criteria for AIDS. The 12 patients had pulmonary symptoms (dyspnea, cough) and fever. On chest X-ray, nodular, interstitial or diffuse parenchymal infiltrates, mediastinal and hilar adenopathies were observed. Two patients had pleural effusion, but none had cavitary lung disease. Mk was isolated by culture of sputum (n = 7), blood (n = 3), bronchial biopsy (n = 2) or bone marrow (n = 1). No patient had clinical extra-pulmonary disease. Survival after diagnosis was in average 7 months. Potential for therapeutic response is reviewed and documented.

[Comparison of lansoprazole (30 mg) and omeprazole (20 mg) in the treatment of duodenal ulcer. A multicenter double-blind comparative trial].

The efficacy of lansoprazole (30 mg/d) and omeprazole (20 mg/d) has been assessed in active duodenal ulcer disease in 144 patients included in a multicentric, randomized, double-blind trial. After two weeks, the healing rates were 74% and 58% in the lansoprazole and omeprazole groups, respectively (P = 0.049). After 4 weeks, the healing rates were 94% in each group (NS). The delay to pain relief was 2 days for lansoprazole and 3 days for omeprazole (NS). Minor side effects occurred in 12% of the lansoprazole treated patients and in 13% of the omeprazole treated patients. No severe adverse events were reported. A slight increase in serum gastrin level was observed, similar in both groups (+35 UI/L and +19 UI/L for lansoprazole and omeprazole respectively). This study confirms previous results concerning the efficacy of both treatments in duodenal ulcer disease. The statistical difference observed for healing rates after 2 weeks could correspond to a faster efficacy for lansoprazole (30 mg) than for omeprazole (20 mg).

[Lactitol in the treatment of constipation in the adult. Open, non-comparative study of its efficacy and its clinical and biological tolerance].

To study clinical and biological tolerability, 114 chronically constipated patients of both sexes, aged 18-70, without any organic alteration of the colon, received lactitol over a period of one or two months. Clinical tolerability was found to be good by 80 per cent of patients and biological tolerability excellent. Clinical efficacy was found correct for 80 per cent of patients with a dosage of 20 g (single dose in the evening). All patients, except one, agreed with the packaging and the taste of the product.

Genetically determined oxidation polymorphism and drug hepatotoxicity. Study of 51 patients.

The influence of genetically determined oxidation polymorphism on drug hepatotoxicity has been poorly investigated and results are controversial. We studied drug oxidation capacity in 51 patients with hepatitis caused mainly by drugs undergoing oxidative metabolism, using dextromethorphan, a test compound recently proposed as a substitute for debrisoquine. Phenotyping was performed using the metabolic ratio (MR) calculated as MR = 0-10 h urinary output of dextromethorphan/0-10 h urinary output of dextrorphan (the main oxidative metabolite), after oral administration of 40 mg dextromethorphan hydrobromide. Dextromethorphan oxidation capacity was similar in patients and in 103 control subjects as judged by: (a) the prevalence of each phenotype (5.9% versus 3.9% for the poor metabolizer phenotype and 94.1% versus 96.1% for the extensive metabolizer phenotype; (b) the frequency distribution histograms of log metabolic ratio; (c) the mean values of dextromethorphan and dextrorphan urinary outputs and of log metabolic ratio for each phenotype. These results show that hepatotoxicity of several drugs, including amineptine, amodiaquine and Plethoryl, is related neither to an impairment in dextromethorphan oxidation capacity nor to an unusually high capacity to oxidize this drug.

Rioprostil and ranitidine in the prevention of duodenal ulcer relapse.

One hundred and ninety duodenal ulcer patients who had relief of pain and endoscopically proven ulcer healing after a short treatment period are allocated at random to double-blind maintenance treatment with a synthetic dehydroprostaglandin-E1, rioprostil, 300 micrograms, or ranitidine, 150 mg, at bedtime for 6 months. Patients are monitored every two months and examined by endoscopy after six months of treatment, or more often if warranted. The cumulative relapse rate in the rioprostil group at six months is 32% (25/78) vs. 28% (20/72) in the ranitidine group. This difference is not significant. The percentage of side effects observed is 17% in the rioprostil group vs. 5% in the ranitidine group, but discontinuation of treatment is observed with the same frequency in the two groups.

Rioprostil vs. ranitidine in duodenal ulcer healing: a double-blind multicentre trial.

A total of 156 patients with endoscopically proven duodenal ulcers are randomized in a double-blind, multicentre trial comparing rioprostil, 300 micrograms b.d., with ranitidine, 150 mg b.d. With rioprostil, the cumulative healing rate by endoscopy is 73% at 4 weeks, and 87% at 6 weeks. With ranitidine it is 79% and 92%, respectively. There is no difference in the occurrence of pain after the two types of treatment, and the side effects are comparable in the two groups. These results show that rioprostil is probably as effective and safe as ranitidine in the treatment of duodenal ulcer.

[Endoscopic removal of a duodenal villous tumor. Review of the literature (author's transl)].

A benign villous tumor of the second duodenum was treated by endoscopic excision. Fifty-four previously published cases are reviewed. Villous tumors of the duodenum are very uncommon. Presenting features include intestinal bleeding and/or occlusive symptoms and/or obstructive jaundice. Diagnosis is established by fiberoptic endoscopy and biopsies. Complete removal of the tumor is mandatory because of the high incidence of malignant changes (approximately 33%). Endoscopic excision is only possible in a small number of cases, when the tumor is small, benign, and pedunculated. Complete removal of the tumor ald unequivocal diagnosis of benign tumor on histological examination are required to withstand from further therapy. The best procedure is often surgical excision or segmentary duodenal resection. This is satisfactory for benign lesions or tumors with focal in situ malignant changes. Pancreatoduodenectomy should be considered for invasive malignant tumors.
