Abstract
Dyslipidemia is common in kidney transplant recipients owing to the disturbance of lipid metabolism caused by chronic kidney disease and the effect of immunosuppression on lipid metabolism. Patients receiving treatment with mammalian target of rapamycin inhibitors show more prominent lipid disorders, which are attributed mainly, but not only, to adipocyte lipid uptake disruption, lipolysis promotion and lipogenic gene expression enhancement. Dyslipidemias in kidney transplant recipients predispose these patients to an increased risk of developing cardiovascular disease; thus, current guidelines recommend treatment initiation with a statin, regardless of low-density lipoprotein cholesterol (LDL-C) concentration, with ezetimibe as a secondary option for patients who do not tolerate such therapy or for those with inadequate response. Treatment with pro-protein convertase subtilisin/kexin type 9 inhibitors such as alirocumab, although effectively reducing LDL-C in patients with chronic kidney disease, has not been evaluated in kidney transplant recipients. In this case report, we present a case of a female kidney transplant recipient who developed substantial dyslipidemia after everolimus initiation. This case was resistant to treatment with simvastatin/ezetimibe combination, and the patient subsequently received alirocumab. Our patient showed a mean reduction of 46.6% in LDL-C during an 18-month period after alirocumab initiation, which is comparable to the results of studies on patients with or without renal impairment. Furthermore, treatment with alirocumab proved to be well tolerated without adverse effects or interactions with the immunosuppression regimen.
