Summary
Maintaining physical activity in patients with diabetic nephropathy may slow disease progression. Restricted exercise showed no significant benefit in delaying advanced kidney disease or the need for dialysis.
Area of Science:
- Nephrology
- Endocrinology
- Exercise Physiology
Background:
- Diabetic nephropathy is a leading cause of chronic kidney disease.
- The role of physical activity in modulating diabetic nephropathy progression remains under investigation.
Purpose of the Study:
- To investigate the impact of maintained versus restricted physical activity on the clinical course of diabetic nephropathy.
Main Methods:
- Patients with diabetic nephropathy were categorized into a physical activity maintained group (G) or a restricted group (R).
- Key clinical milestones including proteinuria levels, serum creatinine, and time to dialysis initiation were monitored.
Main Results:
- The time from 1+ to 3+ proteinuria was longer in the restricted group (68 months) compared to the maintained group (56 months).
- However, the progression from 3+ proteinuria to serum creatinine exceeding 2.0 mg/dl was shorter in the restricted group (23 months) versus the maintained group (29 months).
- Post-dialysis, patients in the maintained group experienced less postural hypotension and demonstrated better functional fitness (Karnofsky score).
Conclusions:
- Strict exercise restriction offers limited benefit in slowing diabetic nephropathy progression, even after macroalbuminuria onset.
- Maintaining physical activity may improve quality of life and reduce complications in patients with advanced diabetic nephropathy.
