Summary

Adult patients undergoing chronic dialysis therapy for at least three months were selected. A physical function assessment was conducted, including the Short Physical Performance Battery (SPPB) and a handgrip strength test. Additionally, a bioelectrical impedance analysis was performed. Subsequently, 5 grams of creatine were administered daily for a period of eight weeks, after which the same assessments were repeated. The results were then analyzed to identify any differences in the tests, aiming to detect potential changes following creatine supplementation.

Detailed description

Adult patients undergoing chronic dialysis therapy for at least three months were selected, primarily based on their good adherence to pharmacological and dialysis treatment regimens. A physical function assessment was conducted, including the Short Physical Performance Battery (SPPB) and a handgrip strength test. Additionally, a bioelectrical impedance analysis was performed. All participants were informed that creatine would be administered and provided written informed consent. The study protocol was approved by the local ethics committee. Creatine supplementation consisted of 5 grams per day for eight weeks. On dialysis days, the dose was administered immediately after the dialysis session. On non-dialysis days, patients were responsible for self-administering the creatine at home. The creatine was diluted in 100 mL of water before ingestion. All assessments were conducted the day following the second dialysis session of the week-on Thursday or Friday, depending on the patient's schedule. There was no control group so pre-creatine measurements were considered as the basal (control) state. Measurements were taken before and after the creatine supplementation period in the same patients. The data were analyzed to evaluate changes in the outcomes following creatine use.
