    Abstract:
    One hundred and seventy-eight patients at risk for gastric carcinoma had upper gastrointestinal endoscopy. Twenty-seven selected patients with the type B of chronic atrophic gastritis, 32 patients with normal mucosa and 47 non-scoped healthy controls were tested for plasma vitamin C, retinol and tocopherol. The total vitamin C level was also assessed in gastric juice of scoped patients. Micronutrient levels were related to gastric pH, nitrites and gastric mucosal pathology. The study showed a higher level of pH (greater than 4) and high nitrites in gastric juice in patients with chronic atrophic gastritis, gastric malignant and dysplastic lesions. Neither the hypochlorhydria nor gastric nitrites affected the prevalence of C. pylori in gastric mucosa. Low gastric and plasma concentrations of vitamin C observed in patients with chronic atrophic gastritis showed an inverted relationship with pH level, and an inter-relationship of other vitamins with antioxidant properties (vitamins A and E).
