One hundred and two patients suffering from giardiasis and/or chronic gastritis were subjected for upper gastrointestinal endoscopy. Purified immune rabbit's serum against Giardia lamblia was used in ELISA and immunoperoxidase (IIP) techniques for detection of Giardia antigen, in the stomach. Results showed that out of 70 cases with intestinal giardiasis, 8 (11.4%) by ELISA and 6 (8.6%) by IIP showed gastric giardiasis. Higher percentage of gastric giardiasis (14%) was encountered in cases with both giardiasis chronic gastritis (50) than in cases with giardiasis alone (5%) but with statistically insignificant difference (P>0.05). None of the cases with chronic gastritis alone (without giardiasis) was positive for gastric giardiasis. Dyspepsia was the main presenting symptom in cases with gastric giardiasis (P |
