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.

[Statistical evaluation of biochemical data by the method of discrimination analysis. Selection of the discriminant biochemical variables. Attempted biochemical discrimination of intrahepatic cholestasis, extrahepatic obstruction and liver cancer].

An original method of statistical treatment of biological data is proposed. It permits satisfactory biochemical classification of 322 patients divided up into 3 groups : intrahepatic cholestasis (235 patients), extrahepatic obstruction (44 patients) and carcinoma of the liver (43 patients). On the basis of 32 tests, it was possible to define discriminating areas permitting satisfactory diagnosis in 95 per cent of published cases. The reduction in the number of tests necessary for diagnosis was considered. The selection technic used was original to the extent that it dose not require, like most methods used today, the determination of better individual discriminators, but the establishment of a better discriminating subunit, obtained from the initial subunit composed of a group of variables. From the 32 parameters contained in the standard liver function tests, a search for a better discriminating subunit consisting of the best four tests, permitted the authors to select a group of 10 tests : bilirubin, alkaline phosphatase, 5-nucleotidase, Thymolturbidity, Cetavlon test, serum albumin, total LDH, TGP (ALAT), OCT, GLDH, of which the discriminating value remains very satisfactory.
