Abstract
Abstract
Background
Dyspepsia is common among end-stage renal disease (ESRD) patients and its association with delayed gastric emptying is not well established. We assessed the association of dyspepsia with gastric emptying time in ESRD patients undergoing hemodialysis (HD).
Methods
Dyspepsia was assessed through the Porto Alegre Dyspeptic Symptoms Questionnaire (PADYQ). PADYQ’s scores ≥ 6 classified participants as dyspeptic. The octanoic acid breath test using 13carbon was employed to assess the gastric emptying time. Based on the test, time in minutes to metabolize the first half of the 13carbon in the test meal (t1/2) was calculated. Association of dyspepsia with gastric emptying time was tested by the correlation between PADYQ scores and t1/2, and also by comparing t1/2 between dyspeptics and non-dyspeptics.
Results
There were 34 (68.0%) dyspeptic patients. Dyspepsia score was positively correlated with t1/2 (r = 0.366; p = 0.009). Dyspeptics had longer t1/2 compared to non-dyspeptics, respectively, 238.0 ± 92.9 versus 185.5 ± 45.5 minutes (p = 0.042).
Conclusions
Delayed gastric emptying was associated with dyspepsia. Prokinetic medications could have a role in preventing or relieving dyspeptic symptoms among HD patients. Future research in larger samples is necessary to confirm this association.
