Background:
Sirolimus is a potent immunosuppressive medication that acts by inhibiting T-cell proliferation. It has been used in kidney transplantation because of its lack of nephrotoxicity. It is now being investigated in liver transplantation, but there are concerns about safety and long-term side effects such as dyslipidaemia. Hypertriglyceridaemia is a common adverse event seen with sirolimus use, and often does not respond to dose reduction or anti-lipemic drugs.
Method:
We report six patients who have developed significant hyperlipidaemia while receiving sirolimus, in spite of therapeutic trough levels.
Conclusion:
All six patients showed either resolution or improvement in lipid levels with discontinuation of sirolimus.
Insights
Sirolimus can cause serious hypertriglyceridaemia in transplant patients. Discontinuing sirolimus effectively resolved or improved lipid levels in all reported cases.
Area of Science:
- Immunology
- Pharmacology
- Transplantation Medicine
Background:
- Sirolimus is an immunosuppressant used in transplantation, valued for low nephrotoxicity.
- Concerns exist regarding sirolimus's safety and side effects, particularly dyslipidemia, in liver transplantation.
- Hypertriglyceridemia is a frequent, often refractory, adverse event associated with sirolimus therapy.
Purpose of the Study:
- To investigate the impact of sirolimus on lipid levels in transplant recipients.
- To assess the safety and efficacy of sirolimus in liver transplantation.
- To evaluate management strategies for sirolimus-induced hypertriglyceridemia.
Main Methods:
- Case series of six patients experiencing significant hyperlipidemia during sirolimus treatment.
- Monitoring of lipid profiles in patients receiving therapeutic trough levels of sirolimus.
Main Results:
- All six patients developed significant hyperlipidemia despite therapeutic sirolimus trough levels.
- Hypertriglyceridemia was a prominent adverse effect observed in the patient cohort.
Conclusions:
- Discontinuation of sirolimus led to resolution or improvement of hyperlipidemia in all patients.
- Sirolimus cessation is an effective strategy for managing sirolimus-induced hypertriglyceridemia.
