Early use of PCSK9 inhibitor therapy after heart transplantation from a hepatitis C virus positive donor

PCSK9 Inhibition in Patients After Heart Transplantation: a Retrospective Review and Literature Analysis

PURPOSE OF REVIEW

Following cardiac transplantation, patients have an increased risk of developing cardiac allograft vasculopathy and atherosclerotic cardiovascular disease. Therefore, aggressive lipid management is indicated. Some patients do not achieve optimal lipid profiles with statin monotherapy, however, or discontinue statins due to intolerance. In this review, we investigated the use of PCSK9 inhibitors as an alternative treatment for hyperlipidemia following cardiac transplantation.

RECENT FINDINGS

Nine published articles were identified that included 110 patients treated with alirocumab or evolocumab after cardiac transplantation. PCSK9 inhibitors were tolerated by all patients, and each study demonstrated an effective reduction of low-density lipoprotein ranging from 40 to 87% decrease from baseline. In our study, the 110 patients from literature review were added to a cohort of 7 similar patients from our institution for combined analysis. This report supports that PCSK9 inhibitors should be considered following cardiac transplantation when conventional medial therapy is not tolerated or ineffective.

PCSK9 inhibitors in a renal transplant patient complicated with hepatitis B: A case report and literature review

Lipid metabolism disorders are recognized to be one of the most frequent complications of renal transplantation, while dyslipidemia and chronic kidney disease (CKD) are strong risk factors for arteriosclerotic cardiovascular disease (ASCVD). Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are novel lipid-lowering drugs, the safety and efficacy of which are yet to be confirmed in transplanted patients. There have been several small-sample studies using PCSK9i in patients after heart transplantation, while fewer cases use PCSK9i after kidney transplantation. We report a case of a renal transplant recipient complicated with hepatitis B treated with PCSK9i, which achieved a remarkable lipid-lowering efficacy, and no significant adverse effects were found during the follow-up.
