摘要

Background-Apheresis is an important treatment for reducing low-density lipoprotein cholesterol (LDL-C) in patients with familial hypercholesterolemia (FH). We systematically reviewed the current literature surrounding LDL-C apheresis for FH. Methods and Results-Electronic databases were searched for publications of LDL-C apheresis in patients with FH. Inclusion criteria include articles in English published in 2000-2013 that provide descriptions of practice patterns, efficacy/effectiveness, and costs related to LDL-C apheresis in patients with FH. Data were stratified by country and FH genotype where possible. Thirty-eight studies met the inclusion criteria: 8 open-label clinical trials, 11 observational studies, 17 reviews/guidelines, and 2 health technology assessments. The prevalence of FH was not well characterized by country, and underdiagnosis was a barrier to FH treatment. Treatment guidelines varied by country, with some guidelines recommending LDL-C apheresis as first-line treatment in patients with homozygous FH and after drug therapy failure in patients with heterozygous FH. Additionally, guidelines typically recommended weekly or biweekly LDL-C apheresis treatments conducted at apheresis centers that may last 2 to >3 hours per session. Studies reported a range for mean LDL-C reduction after apheresis: 57-75% for patients with homozygous FH and 58-63% for patients with heterozygous FH. Calculated annual costs (in US$2015) may reach US$66 374 to US$228 956 per patient for weekly treatment. Conclusions-LDL-C apheresis treatment may be necessary for patients with FH when drug therapy is inadequate in reducing LDLC to target levels. While apheresis reduces LDL-C, high per-session costs and the frequency of guideline-recommended treatment result in substantial annual costs, which are barriers to the optimal treatment of FH.
