Dyspepsia Amongst End Stage Renal Disease Undergoing Hemodialysis: Views from a Large Tertiary Care Center

Gastrointestinal symptoms are common in patients with end stage renal disease (ESRD) among which dyspepsia is frequently observed. The aim of the study was to determine the frequency and associations of dyspepsia in ESRD patients using the Leeds questionnaire.

All ESRD patients on maintenance hemodialysis were consecutively enrolled in the study. Leeds questionnaire was used to interrogate the patients for the assessment of dyspepsia. Mean and standard deviation were calculated for age, body mass index (BMI), disease duration and number of hemodialysis sessions. Independent t-test and Chi square tests were used for statistical analysis.

Total number of patients was 200, out which 118 (59.3%) were male. The mean age was of 41.4 years. According to the Leeds questionnaire, dyspepsia was present in 62 (63.9%) patients. Younger patients (age 20-40 years) more frequently had dyspeptic symptoms (61.5% patients), retrosternal pain (156 patients, 78.0%), regurgitation (127 patients, 63.5%), dysphagia (67 patients, 33.5%), and nausea (142 patients, 71.0%). Patients presented with intermittent pattern of symptoms in 179 (89.5%) cases, while continuous symptoms in 6 (3.0%). Dyspepsia was associated with aspartate aminotransferase (AST) levels > 25 U/L (P = 0.001), alanine aminotransferase (ALT) levels > 28U/L (P = 0.000) and gamma glutamyl transferase (GGT) levels > 34 U/L (P = 0.002). On multivariate analysis, urea, creatinine, and presenting symptoms of dysphagia and belching showed significant statistical association with dyspepsia.

Dyspepsia is a common problem affecting patients with end stage renal disease and is associated with raised serum AST, ALT and GGT in such patients.
