Impact of coinfection with Schistosoma mansoni on Helicobacter pylori induced disease.

The impact of concomitant S. mansoni infection on H. pylori induced gastritis was studied in twenty patients infected exclusively with H. pylori. The patients were compared with twenty patients coinfected with the bacteria and S. mansoni and twelve patients with schistosomiasis alone. All patients were subjected to clinical, parasitological, endoscopic and histopathological studies. In addition, serum malondialdehyde level (MDA), as an indicator of lipid peroxidation was measured. The results of revealed that severe gastritis was significantly more common in the patients infected exclusively with H. pylori. Serum MDA was significantly higher in this group compared to the other groups. The results were discussed.
