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 LDL-C 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.
