Background

Apolipoprotein E (APOE) and APOA5 play an important role in lipid transport and metabolism. Polymorphisms in APOE and APOA5 have been reported to be associated with baseline lipid levels and lipid responses to statins in different populations.

Objective

This study evaluated associations of APOE and APOA5 genotype with baseline lipid levels and response to rosuvastatin in Chinese patients with hyperlipidemia.

Methods

A total of 386 patients with hyperlipidemia, including 166 with familial hypercholesterolemia (FH), with good adherence to rosuvastatin 10 mg daily, were genotyped for the APOE e2/e3/e4 and APOA5 −1131T>C polymorphisms. The lipid profile was examined before and after at least 4 weeks of therapy.

Results

In patients without FH, there was a trend that e2 carriers had lower and those e4 carriers had higher low-density lipoprotein cholesterol (LDL-C) levels than subjects with the e3/e3 genotype (P > .05). However, an opposite significant association between APOE polymorphisms and LDL-C levels was observed in patients with FH (P = .005). The APOA5 −1131C variant allele was associated with increased baseline triglycerides levels in both patients with and without FH (P < .005 for both). Neither APOE nor APOA5 polymorphisms showed a significant effect on the lipid responses to rosuvastatin.

Conclusions

This study demonstrates different associations of APOE polymorphisms with baseline LDL-C concentrations in Chinese patients with or without FH and confirms the strong relation between the APOA5 polymorphism and baseline triglyceride levels. These findings expand our knowledge on the genetic determinants of lipids and lipid response to rosuvastatin in Chinese patients with hyperlipidemia.

  Familial hypercholesterolemia (FH) is a dominantly inherited disorder present from birth that markedly elevates plasma low-density lipoprotein cholesterol and causes premature coronary heart disease. There are at least 20 million people with FH worldwide, but the majority remains undetected, and current treatment is often suboptimal. To address this major gap in coronary prevention we present, from an international perspective, consensus-based guidance on the care of FH. The guidance was generated from seminars and workshops held at an international symposium. The recommendations focus on the detection, diagnosis, assessment, and management of FH in adults and children and set guidelines for clinical purposes. They also refer to best practice for cascade screening and risk notifying and testing families for FH, including use of genetic testing. Guidance on treatment is based on risk stratification, management of noncholesterol risk factors, and the safe and effective use of low-density lipoprotein-lowering therapies. Recommendations are given on lipoprotein apheresis. The use of emerging therapies for FH is also foreshadowed. This international guidance acknowledges evidence gaps but aims to make the best use of contemporary practice and technology to achieve the best outcomes for the care of FH. It should accordingly be used to inform clinical judgment and be adjusted for country-specific and local healthcare needs and resources.
