This study aimed to assess serum iron, zinc, and copper in symptomatic children with Helicobacter pylori infection, to correlate their serum levels with the degree of gastritis, and to evaluate the effect of H. pylori treatment on their levels.
This study was carried out on 70 children with upper gastrointestinal tract symptoms. H. pylori infection was diagnosed by the H. pylori antigen test in the stool and histopathologic findings during upper gastrointestinal endoscopy. Patients were divided into 2 groups; H. pylori-positive and H. pylori-negative groups. Hemoglobin, serum ferritin, transferrin (sTfR), zinc, and copper were assessed in all included children.
The hemoglobin level, serum ferritin, and zinc were significantly lower in H. pylori-positive patients compared to H. pylori-negative patients. However, the serum copper level was comparable between the 2 groups. After treatment, the hemoglobin level, serum ferritin, and serum zinc significantly increased in H. pylori-positive patients, especially in those who responded to treatment compared to their levels before treatment. There was a significant negative correlation between the severity of histopathologic abnormalities and hemoglobin level, serum ferritin, and zinc levels, but a significant positive relation with sTfR concentrations in H. pylori-positive patients.
H. pylori-infected children had low serum ferritin and zinc levels but high sTfR level with no effect on serum copper levels. After treatment, hemoglobin, serum ferritin, and zinc levels significantly improved in H. pylori-positive patients. Gastric histologic findings correlated significantly with hemoglobin, serum ferritin, zinc, and sTfR levels.
