[Chronic gastric ulcer in a child with Glanzmann thrombasthenia. Usefulness of prostaglandin E2].

Gastric ulcers in children are often seen as a result of an imbalance between nocive factors and the resistance of the mucosa. Glanzmann's thromboastenia is a defect in platelet aggregation and its nature may be associated to local factors which precipitate or perpetuate bleeding. Prostaglandins are hormones of local action which inhibit the secretion of acid and therefore protect the mucosa. We report a case of an 18 year old male youngster with Glanzmann's thromboastenia and a gastric ulcer previously unsuccessfully treated with cimetidine, aluminum hydroxide solution, ranitidine, sucralfate and later controlled with PGE2. In sum, the usefulness of the cytoprotecting effects of the prostaglandins are successfully evaluated in a young man with platelet aggregation abnormalities.

[Drug therapy of peptic ulcer. What is coming up?].

Prostaglandin-E analogues inhibit gastric acid secretion after oral administration. Therefore, these drugs are tested in clinical trials and one of them--Misoprostol--has recently been registered. With regard to healing rate of peptic ulcers and improvement of clinical signs and symptoms the prostaglandin analogues are superior to placebo but only equally effective or even slightly inferior to H2-receptor blockers. Side effects such as diarrhea or uterotropic actions will probably limit their broad application. The exact therapeutic effectiveness of prostaglandin analogues in treatment of peptic ulcer remains to be evaluated in greater detail. The substituted benzimidazole omeprazole is the first drug which exerts a long lasting and almost complete suppressive effect on gastric acid secretion in humans. This unique inhibition leads to a significant and more rapid healing rate of duodenal ulcers compared to treatment with H2-blockers. Additionally, peptic ulcers resistant to H2-blocker therapy can be treated effectively with omeprazole. In spite of these promising results the exact therapeutic effectiveness of this drug requires further evaluation.

[Therapy and prevention of peptic lesions by prostaglandins].

Prostaglandin-E-analogues inhibit gastric acid secretion after oral administration. Therefore, these drugs are tested in clinical trials and two of them- misoprostol and rosaprostol-has recently been registered. With regard to healing rate of peptic ulcer and improvement of clinical signs and symptoms the prostaglandin analogues are superior to placebo but only equally effective or even slightly inferior to H2-receptor blockers. The relapse rates following successful therapy with prostaglandin analogues are similar to that with H2-blockers. Side effects such as diarrhea or uterotropic actions will probably limit their broad application. The exact therapeutic effectiveness of prostaglandin analogues in treatment of peptic ulcer remains to be evaluated in greater detail. As in the treatment of peptic ulcer disease prostaglandin-analogues are only effective in preventing NOSAC-induced peptic lesions when given in antisecretory doses.
