Comprehensive treatment with dapagliflozin in elderly chronic kidney disease patients: Clinical efficacy and impact on body composition.

BACKGROUND

Dapagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, is widely used for treating heart failure and chronic kidney disease (CKD). While its renoprotective effects are well established, concerns remain regarding its impact on muscle mass and function, especially in elderly patients.

OBJECTIVE

To assess the effects of dapagliflozin on renal function, body composition, and muscle strength in elderly CKD patients.

METHODS

Twelve elderly CKD patients (75.6 ± 1.4 years) were treated with dapagliflozin for 12 months. Body composition, serum parameters, and muscle function were evaluated at baseline, 6 months, and 12 months. Measurements included changes in eGFR, liver function, HbA1c, and muscle strength.

RESULTS

Dapagliflozin treatment stabilized eGFR without significant improvement, but proteinuria was notably reduced in most patients, indicating a positive renal effect. AST and ALT levels showed significant reduction after 12 months, suggesting improved liver function. No significant changes were observed in body weight, BMI, or muscle mass. Muscle function, as measured by the 5-sit-to-stand test, improved significantly, while grip strength remained stable. No serious adverse events were reported.

CONCLUSION

Dapagliflozin is a safe and effective treatment for CKD in elderly patients, demonstrating renal protection and improved liver function without adversely affecting muscle mass or strength. The study supports the use of dapagliflozin as part of a comprehensive approach, combining pharmacotherapy, lifestyle modification, and exercise to optimize patient outcomes in CKD management.
