Effect of Helicobacter pylori eradication on gastric histology, serum gastrin and pepsinogen I levels, and gastric emptying in patients with gastric ulcer.
The evolution of gastritis and the behavior of basal and meal-stimulated gastrin release, pepsinogen levels, and gastric emptying of solids were studied in a series of consecutive patients with Helicobacter pylori-positive, uncomplicated, non-NSAID-related type I gastric ulcer over a follow-up period of 3 months after eradication therapy was begun. ⋯ Our findings suggest that in non-NSAID-related type I gastric ulcers, the eradication of H. pylori significantly reduces gastritis activity and inflammatory scores, but not atrophy and intestinal metaplasia, and modifies gastrin and pepsinogen I release in a short follow-up period. In contrast, H.pylori eradication does not significantly affect gastric emptying of solids, at least within a period of 3 months from therapy.

Autoimmune hemolytic anemia and positive Coombs test associated with ulcerative colitis.
To estimate the frequency of autoimmune hemolytic anemia and Coombs positivity without overt hemolysis in ulcerative colitis, to determine possible subsets of patients with ulcerative colitis susceptible to this complication, and to assess the efficacy of the applied therapeutic modalities. ⋯ In this study, the frequency with which autoimmune hemolytic anemia was associated with ulcerative colitis was higher than in previous reports. The complication occurred early in the course of colitis and was related to activity and extent of the disease. In contrast to others studies, we found a preponderance of males. Although corticosteroids and/or immunosuppressive therapy was successful in most of our cases, one patient required surgery.
