Switching from lipoprotein apheresis to evolocumab in FH siblings on hemodialysis: case reports and discussion

AbstractFamilial hypercholesterolemia (FH) and chronic kidney disease, especially end-stage renal disease (ESRD), are common and put patients at a high risk of developing atherosclerotic cardiovascular disease (ASCVD). ESRD concomitant with FH may further increase the risk of ASCVD. Achieving target levels of low-density lipoprotein cholesterol (LDL-C) is difficult owing to the limitations of statin administration due to its side effects in ESRD. Therefore, some FH patients with ESRD require lipoprotein apheresis for the prevention of secondary ASCVD events. Although proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors may offer a safe and effective option for lowering lipid levels in such patients, no guidelines are available for their use. Here, we report the case of two male siblings with FH in secondary prevention undergoing hemodialysis combined with PCSK9 inhibitor treatment. The siblings, who showed a heterozygous c.1846-1G>A mutation in theLDLR gene, underwent hemodialysis. In combination with the lipoprotein apheresis, siblings were administered evolocumab, a PCSK9 inhibitor. Both the siblings had coronary artery disease, diabetes, and ESRD, and received hemodialysis. Their LDL-C levels did not reach the target values despite administering statin, ezetimibe, and biweekly lipoprotein apheresis. On the introduction of evolocumab treatment, their LDL-C levels were significantly reduced without any adverse effects, resulting in successful withdrawal from lipopr...
