Obesity in kidney transplantation

Area of Science:

• Nephrology
• Transplantation immunology
• Cardiovascular medicine

Background:

• Kidney transplantation is the primary treatment for end-stage renal disease.
• Cardiovascular disease is a major cause of mortality and graft loss post-transplantation.
• Obesity is a prevalent risk factor for cardiovascular disease, impacting transplant outcomes.

Purpose of the Study:

• To review the literature on pre- and post-transplant obesity's effects on patient and graft survival.
• To discuss obesity-related mechanisms contributing to adverse kidney transplant outcomes.
• To explore nutritional interventions for improving long-term transplant success.

Main Methods:

• Literature review of studies assessing obesity in kidney transplant recipients.
• Analysis of mechanisms linking obesity to cardiovascular disease and transplant complications.
• Evaluation of nutritional interventions for weight management post-transplantation.

Main Results:

• Post-transplant obesity is associated with increased risk of graft failure and mortality.
• The impact of pre-transplant obesity on outcomes remains uncertain.
• Nutritional interventions effectively promote post-transplant weight loss, but long-term outcome data are limited.

Conclusions:

• Post-transplant obesity poses a significant threat to kidney transplant recipients' survival.
• Further research on nutritional interventions is crucial to improve long-term kidney transplant outcomes.
• Targeting post-transplant weight management may enhance graft and patient longevity.
