Conditions

• H Pylori Infection

Interventions

• GENETIC: detection of vacuolating cytotoxin A (Vac A) and cytotoxin-associated gene A (Cag A) virulent H.Pylori genotypes by polymerase chain reaction amplification(PCR) in gastric biopsies :
• DIAGNOSTIC_TEST: Culture and sensitivity of endoscopic gastric biopsies:
• OTHER: Histopathological examination endoscopic gastric biopsies:
• PROCEDURE: Upper endoscopy
• DRUG: empirical H.pylori regimens
