Effect of diet on posttransplant hyperlipidaemia

Area of Science:

• Nephrology
• Cardiology
• Nutritional Science

Background:

• Post-transplant hyperlipidemia is a common complication in renal transplant recipients.
• It increases the risk of cardiovascular disease, impacting long-term graft and patient survival.

Purpose of the Study:

• To evaluate the efficacy of a three-month dietary intervention in managing hyperlipidemia in stable renal transplant patients.
• To assess the impact of dietary changes on plasma lipid and apolipoprotein concentrations and lipoprotein patterns.

Main Methods:

• Twenty-five renal transplant recipients with hyperlipidemia and stable graft function participated.
• A controlled diet was implemented, focusing on reduced energy intake, restricted fat (25-30%), low saturated fat (<10%), and limited cholesterol (<300 mg/d).
• Lipid profiles, apolipoproteins, and lipoprotein electrophoresis were measured before and after the three-month dietary period.

Main Results:

• Significant reduction in the cholesterol/HDL cholesterol risk ratio and a significant increase in HDL cholesterol concentration were observed.
• Six patients normalized their lipoprotein electrophoretic patterns, with substantial decreases in total cholesterol, LDL cholesterol, and apoB/apo A-1 ratio.
• Most participants showed improvements in various lipid parameters following dietary modifications.

Conclusions:

• Dietary modification is an effective initial approach for managing hyperlipidemia in renal transplant recipients.
• This intervention can lead to significant improvements in cardiovascular risk factors, including lipid profiles.
• Further research may explore long-term outcomes and combination therapies.
