RESUMO

OBJECTIVE To systematically evaluate the effects of C3435T polymorphism in ABCB1 gene on lipid-lowering efficacy of statins. METHODS Retrieved from PubMed, Web of Science, the Cochrane Library, CNKI and VIP, the cohort studies on the use of statins were collected from the inception to November 1, 2023. After literature screening, data extraction and quality evaluation, meta-analysis was performed by using RevMan 5.4 software. RESULTS A total of 11 literature involving 1 575 patients were included. The results showed that under the dominant genetic model, the reduction of low-density lipoprotein cholesterol (LDL-C) [MD=-1.87, 95%CI (-3.62, -0.13), P=0.04], total cholesterol (TC) [MD=-1.42, 95%CI (-2.80, -0.04), P=0.04] in patients with CT+TT genotype was significantly higher than CC genotype. There was no significant difference in the increase of high-density lipoprotein cholesterol (HDL-C) [MD=-0.65, 95%CI (-2.48, 1.18), P=0.49] or the decrease of triglyceride (TG) [MD=-0.05, 95%CI (-2.94, 2.84), P=0.97] between patients with CT+TT genotype and CC genotype. Under the recessive genetic model, the reduction of TC [MD=2.26, 95%CI (0.97, 3.56), P=0.000 6] and the increase of HDL-C [MD=2.38, 95%CI (0.42, 4.35), P=0.02] in patients with TT genotype were significantly higher than CC+ CT genotype. There was no significant difference in the reduction of LDL-C [MD=1.53, 95%CI (-0.10, 3.15), P=0.07] or TG [MD=0.06, 95%CI (-2.98, 3.10), P=0.97] between CC+CT genotype and TT genotype. Under the additive genetic model, the reduction of TC [MD=2.98, 95%CI (1.27, 4.69), P=0.000 6] and LDL-C [MD=2.84, 95%CI (0.67, 5.01), P=0.01] in patients with TT genotype were significantly higher than CC genotype. There was no significant difference in the increase of HDL-C [MD=2.40, 95%CI (-0.17, 4.97), P=0.07] or the decrease of TG [MD=0.97, 95%CI    (-2.93, 4.87), P=0.63] between patients with TT genotype and CC genotype. CONCLUSIONS The reduction of LDL-C and TC in patients with dyslipidemia treated with statins may be related to the heterozygous and homozygous mutation of C3435T in ABCB1 gene, and the reduction of LDL-C and TC in patients with CT or TT genotype is more obvious, compared with patients with CC genotype. The elevation of HDL-C may be related to homozygous mutation, and the effect of HDL-C elevation may be more obvious in patients with TT genotype, compared with CC+CT genotype. However, the change of TG may not be related to the C3435T polymorphism in ABCB1 gene.
