Absolute ethanol and 5% ethanolamine oleate are comparable for sclerotherapy of esophageal varices.

BACKGROUND: Endoscopic sclerotherapy is widely accepted as an effective treatment for the eradication of esophageal varices in patients with portal hypertension and a history of upper gastrointestinal bleeding. The objective of this study was to assess the effectiveness and safety of absolute ethanol as an alternative sclerosing agent to the commonly used 5% ethanolamine oleate. METHODS: One hundred fifty-seven patients with portal hypertension and a history of variceal bleeding were randomly assigned to sclerotherapy with absolute ethanol (n = 66) or 5% ethanolamine oleate (n = 91) between January 1992 and July 1994. Once eradication was achieved, these patients were prospectively followed until September 1998. RESULTS: Sclerotherapy with both sclerosants resulted in similar eradication rates (approximately 90%), with comparable numbers of sessions required for eradication (5.4 and 5.9 sessions for absolute ethanol and 5% ethanolamine oleate, respectively). Similar complication and recurrent bleeding rates were observed among both groups. CONCLUSION: Sclerotherapy with absolute ethanol is as effective as with 5% ethanolamine oleate in preventing further bleeding in patients with portal hypertension.

Effects of intravenous glucose and aminoacids on gastric secretion.

Five healthy females were submited to parenteral nutrition with aminoacids and glucose solution and the acidity and volume of gastric juice were studied. We could find no difference in the obtained values at the various phases, even after the administration of betazole. From this we can conclude that the infusion of aminoacids and glucose does not alter the pattern of gastric secretion.

Ursodeoxycholic acid does not interfere with in vivo Helicobacter pylori colonization.

A low frequency of Helicobacter pylori in the gastric mucosa of patients with alkaline gastritis has been reported. At the same time, it can be noted that the growth of bacteria can be inhibited by bile acids. We studied 40 patients with chronic gastritis related to Helicobacter pylori in order to determine the effect of ursodeoxycholic acid on this infection. Diagnoses of the infection and the inflammatory process were obtained by histologic study of gastric biopsies collected during endoscopy. Two groups were studied: group I received ursodeoxycholic acid - 300 mg/day, and group II received the placebo, twice a day, both for 28 days. The colonization by Helicobacter pylori and the intensity of the mononuclear and polymorphonuclear inflammatory infiltrate were determined before (time 1) and after (time 2) treatment. Ursodeoxycholic acid had no effect on the Helicobacter pylori infection. A significant reduction in the intensity of the mononuclear inflammatory infiltrate of the gastric antrum mucosa was observed in patients from group I, when we compared not only times 1 and 2 but also groups I and II. However, this was not the case with the body mucosa. We concluded that ursodeoxycholic acid had no action on the colonization by Helicobacter pylori or on the polymorphonuclear inflammatory infiltrate, but it caused a significant reduction in the intensity of the mononuclear inflammatory infiltrate of the gastric antrum.

[Effect of H2 blockers on the surgical indications for peptic ulcer].

The effects of introduction of cimetidine therapy were studied by an analysis of all cases of peptic ulcer who came to be operated at the Hospital das Clinicas of the University of São Paulo in the period between 1966 and 1985. A reduction in the frequency of surgical interventions especially after 1978, was verified. Ten percent of all cases operated between 1973 and 1985 and chosen at random were studied in a more detailed way. A reduction in the number of operations for gastric and duodenal ulcers was found. There was a greater interval between diagnosis and surgery, an increased number of operations for stenosis and hemorrhagic peptic ulcers and a reduction in frequency of operations for perforated peptic ulcer. There were no significant differences as to the sex and age of patients, except in cases of perforated peptic ulcer, with a larger number of female patients.
