Delayed gastric emptying and Helicobacter pylori infection in patients with chronic renal failure.
Forty patients with chronic renal failure (CRF) were enrolled in this study. Twelve of the 40 patients had upper gastrointestinal symptoms or signs (GI Sx). Twenty of the 40 patients had been receiving regular haemodialysis (HD) for at least 1 year prior to the study. Radionuclide-labelled solid meals were used to calculate gastric emptying times (GETs). The carbon-14 urea breath test (14C4-UBT) was used to diagnose Helicobacter pylori (HP) infection. Among the 40 patients, 35 (88%) had an abnormal GET and 22 (55%) had a positive 14C-UBT for HP infection. There were no statistically significant differences in the incidence of abnormal GET among patients with HP infection and patients without HP infection. There were also no significant differences in the incidence of HP infection among patients with abnormal and normal GETs. In addition, the incidences of abnormal GET in patients with and without upper GI Sx were 83% and 89% respectively. The incidences of HP infection in patients with and without upper GI Sx were 58% and 54%, respectively. The incidences of abnormal GET in HD and non-HD patients were 95% and 80%, respectively. The incidences of HP infection in HD and non-HD patients were 45% and 65%, respectively. The differences in the incidences of abnormal GET and HP infection among HD and non-HD patients, as well as among patients with and without upper GI Sx, were not statistically significant.
