Intradialytic exercise may improve survival rates in adult patients receiving hemodialysis
Patients with kidney failure have a high mortality rate. There is an exponential increase in the number of patients experiencing kidney failure requiring treatment with life-saving kidney replacement therapy (KRT), including hemodialysis (HD), peritoneal dialysis (PD) or kidney transplantation.
Researchers have found inj a new study that Intradialytic exercise may improve survival rates in adult patients receiving hemodialysis.
The new study has been published in the BMC Nephrology.
Patients with kidney failure have a high mortality rate. This study aimed to evaluate the effect of intradialytic exercise on survival in patients receiving hemodialysis (HD).
In this randomized controlled trial conducted in a HD center in Iran, adult patients receiving chronic HD were randomized to intradialytic exercise (60 min) in the second hour of thrice weekly dialysis for 6 months (intervention) or no intradialytic exercise (control). The primary outcome was survival rate at 12 months. Secondary outcomes were serum albumin, hemoglobin, hematocrit, red blood cell count, serum calcium, serum phosphorous, parathyroid hormone, physical function (6-min walk test) and nutritional status (Geriatric Nutritional Risk Index) during the first 6 months. The trial follow-up period was 12 months.
Results
The study included 74 participants (44 males) with an age average of 64 ± 12 years old and a dialysis history of 27 ± 12 months, randomized to intervention (n = 37) or control (n = 37). Compared with controls, 1-year survival was higher in the intervention group
The hazard ratio in univariate analysis in intervention group was 0.17 compared to that in control group.
During the 6-month intervention period, significant between-group changes were observed in all secondary outcomes between the intervention and control groups.
Intradialytic exercise performed for at least 60 min during thrice weekly dialysis sessions improves survival in adult patients receiving HD.
