  • Title: Helicobacter pylori, gastritis and non-ulcer dyspepsia in Ethiopian patients.
    Author: Tsega E, Gebre W, Manley P, Asfaw T.
    Journal: Ethiop Med J; 1996 Apr; 34(2):65-71. PubMed ID: 8840608.
    Abstract:
    The aim of this study is to find out the prevalence of Helicobacter pylori infection in patients with nonulcer dyspepsia (NUD) and asymptomatic controls and to see if there is an etiological association between gastritis, NUD and Helicobacter pylori. One hundred thirty six patients with NUD and 71 controls had six endoscopic biopsies from different sites of the gastric mucosa for histological diagnosis. Helicobacter pylori was looked for in all biopsy specimens utilizing half Gram, Giemsa and Gimenez staining techniques. Type B chronic gastritis was detected in 96% of the NUD cases and in 100% of the asymptomatic controls (P > 0.05). Helicobacter pylori was found in 82 (65%) patients with NUD and in 38 (56%) asymptomatic controls (P > 0.05). Type B chronic gastritis is almost universal in both NUD cases and asymptomatic controls. There is no difference in the prevalence of Helicobacter pylori infection between the two groups. The absence of Helicobacter pylori in a significant number of patients (36%) and controls (45%) with gastritis contradicts the etiological association between Helicobacter pylori and gastritis reported by others, suggesting that in Ethiopia there may be a chronic environmental gastritis which may not be helicobacter-related. There is no correlation between NUD and Type B gastritis, and between symptoms and Helicobacter pylori infection in this population.
