Exercise and Prediabetes After Renal Transplantation (EXPRED-I): A Prospective Study.

Area of Science:

• Nephrology
• Endocrinology
• Exercise Physiology

Background:

• Post-transplant diabetes mellitus (PTDM) is a serious complication after renal transplantation, often developing in patients with prediabetes.
• Late PTDM, occurring beyond 12 months post-transplant, is particularly concerning.
• The role of exercise in preventing late PTDM in prediabetic renal transplant recipients remains understudied.

Purpose of the Study:

• To investigate the efficacy of exercise in reverting prediabetes in renal transplant patients.
• To assess the potential of exercise interventions to prevent late-onset PTDM.
• To evaluate the impact of exercise on glucose metabolism and insulin sensitivity in this population.

Main Methods:

• A 12-month exploratory study involving renal transplant patients with prediabetes.
• Intervention included a structured aerobic and/or strength training program with adherence support.
• Prediabetes reversibility was assessed every 3 months using oral glucose tolerance tests (OGTT).

Main Results:

• The study was halted early due to efficacy, with 60% (16/27) of patients reverting to normal glucose levels.
• Significant improvements were observed in fasting and post-OGTT glucose levels.
• Insulin sensitivity notably improved in patients who reverted from prediabetes compared to those who did not.

Conclusions:

• Exercise training is effective in improving glucose metabolism in renal transplant recipients with prediabetes.
• Personalized exercise prescription and adherence strategies are crucial for successful outcomes.
• This intervention shows promise in preventing late PTDM after renal transplantation.
