title: [Gastroduodenitis and Helicobacter pylori in uremic patients].
abstract: We studied 26 patients (p) with end stage renal failure (RF) and 26 healthy volunteers (HV) to investigate the prevalence of Helicobacter pylori (Hp) and its relation with chronic gastritis (CG) and chronic duodenitis (CD). We analyzed 312 gastric and duodenal mucosal biopsies stained with H & E and Giemsa. Categorical data were assessed by the X2 and Fisher's exact test. Probability values of p < 0.05 were considered significant. Endoscopic lesions correlated with histological gastritis and duodenitis and Hp was positive in antrum of 6/8p (75%) (p < 0.05). The prevalence of Hp was 54.5% (15/26p) in RF and 47.2% (12/26s) in HV. Hp was found more frequently in pathological mucosa (p < 005.). CG of the antrum and CD were more commonly in RF (88.5% vs 69.5% and 42.3% vs 23.1% respectively). HP was more frequently located in the antrum than in body and duodenum in both groups (p < 0.05). Chronic gastritis of the body was more frequently in HV (p < 0.05). Active chronic antral gastritis and superficial gastritis were more frequently associated to Hp. Hp was associated to chronic inflammatory gastroduodenal diseases in both groups and may be a cofactor in its pathogenesis. We recommended Hp treatment before renal transplantation.
