Abstract
BackgroundChronic low-grade inflammation is a feature of chronic kidney disease associated with increased risk of multiple morbidities and mortalities. Hemodialysis (HD) patients lead a sedentary life style which may aggravate their inflammatory state and practicing exercise may improve this condition. The aim of this work was to study the effect of intradialytic exercise (IDE) on inflammatory markers in HD patients.ResultsThis prospective cohort study included 40 HD patients, divided into 2 groups: exercise group completed IDE for 3 months and non-exercise group matched in age and sex as controls. At baseline, there was no difference between both groups regarding physical performance assessed using short physical performance battery test (SPBT) or inflammatory markers C-reactive protein (CRP) and interleukin 6 (IL-6) P > 0.05. After 3 months, SPBT significantly improved in exercise group (P < 0.001). Also, both serum CRP and IL-6 levels showed significant decrease in exercise group compared to baseline (P < 0.001), while no similar change was noticed in non-exercise group.ConclusionsRegular intradialytic aerobic exercise program can improve physical function and inflammation in hemodialysis patients. Further studies on larger number of patients are warranted.
