Background : Upper gastrointestinal (UGI) diseases are more common in patients with end-stage renal disease (ESRD)
compared to general populations. Previous studies demonstrated that ESRD patients with UGI disease are at increased risk
for developing complications following kidney transplantation (KT). Prevalence of UGI lesions and Helicobacter pylori in
asymptomatic KT candidates remain unclear.
Objective : To evaluate the prevalence of UGI lesions and Helicobacter pylori in nondyspeptic KT candidates.
Material and Method: The authors retrospectively and prospectively enrolled consecutive patients with ESRD who underwent
esophagogastroduodenoscopy (EGD) as part of pre-KT evaluation at a single tertiary center (Rajavithi Hospital, Bangkok)
between 2008 and 2013. Patients with significant dyspeptic symptoms, known UGI disease and received PPI/NSAIDs/
antibiotics within two weeks before EGD were excluded. EGD was performed with random biopsies for rapid urease test and
histology.
Results : In all, 107 ESRD patients were included; 53.0% were men and a median age was 38.7 (15.9-65.0) years. A total of
95% of patients had been on hemodialysis with the median duration of 2.1 (0.2-15.3) years. Significant EGD findings (defined
as lesions other than normal and nonerosive gastritis) were encountered in 46% of patients; most lesions were erosive
gastroduodenitis and peptic ulcers. Among several baseline demographic and laboratory parameters analyzed, only older
age was significantly associated with significant EGD findings (p = 0.026). Helicobacter pylori infection was documented in
27.1% of patients. This prevalence tended to be lower than the prevalence of H. pylori of 39% in 105 sex- and age-matched,
nonESRD patients without significant EGD findings who underwent EGD during the same time, but not statistically significant
(p = 0.08).
Conclusion : The authors demonstrated a considerable prevalence of acid-related UGI diseases and H. pylori infection in
nondyspeptic KT candidates. Therefore, EGD is a reasonable part of routine preKT evaluations, at least in our part of the
world, to promptly detect and precisely manage the problem.
