Brief Summary
Upper gastrointestinal (GI) symptoms are frequent in organ transplant recipients. Peptic ulcers and related pathologies such as gastritis and duodenitis are known to occur with increased frequency (20-60%) and severity in renal transplant recipients. The frequency of severe complications is about 10% among transplant recipients and 10% of those might prove fatal As kidney transplant recipients have to take immunosuppressive drugs for a lifetime and because these drugs have many side effects that may not be differentiated from H. pylori infection Thus, in order to reduce the use of medications and subsequently to reduce the drug interactions ,proper detection and management of H pylori infection in those patients is preferred.

Outcome Measures
Primary Outcomes (2)
Prevalence of H pylori post Renal Transplant Patients
Percentage of H pylori positive patients in post renal transplant patients
1 year
Detection of CagA & VacA Genotypes by PCR:
Amplified DNA will be analyzed by agarose gel electrophoresis. The positive sample will produce bands at DNA fragment 138-bp for CagA, 259/286-bp for VacA S1/S2, 290-bp and 352-bp for m1 \& m2, respectively.
1 year
Interventions
All patients will be screened for H. pylori using fecal Ag and positive patients will do endoscopy and biopsy.
Eligibility Criteria
Post renal transplant patients, and patients proven to be h pylori positive will be subjected to further evaluation.
You may qualify if:
- Age ≥ 18 years.
- Patients in the first 1st. year after kidney transplantation.
- Patients diagnosed to have H.pylori infection by H.pylori fecal Ag will do endoscopy and biopsy.
You may not qualify if:
- Patients who had previous upper endoscopy with evidence of gastritis or ulcers
- Age more than 65 years old
- Patients with any contraindications to upper endoscopy.
