BACKGROUND
Antipsychotic-induced weight gain (AIWG) is a crucial factor for the medication cessation of patients with schizophrenia. Multiple studies have shown that the functional polymorphism -759 C/T (rs3813929) in the promoter region could possibly be correlated with AIWG.
AIM
To evaluate the genetic association of the HTR2C-759C/T polymorphism and AIWG in patients with schizophrenia with antipsychotic drugs (APDs) administration.
METHODS
Eligible studies were identified by searching the following databases: PubMed, Embase, Web of Science, China Nation Knowledge Infrastructure (CNKI), VIP, Wanfang Data, Chinese Biomedical Literature Database (CBM) and the Airiti Library. The quality of studies was evaluated based on the Newcastle-Ottawa Scale. The pooled OR and 95% CI were calculated for the dominant (CT/TT/T vs CC/C) mode, and subgroup analyses were performed based on ethnicity, antipsychotic medication and gender; all statistical analyses were performed using the statistical software STATA V.12.0.
RESULT
A total of 17 studies with 3170 patients with schizophrenia were included in our meta-analysis. The result of the meta-analysis has shown that the association between the -759 C/T polymorphism and AIWG is statistically significant (OR 0.34, 95% CI: 0.20 to 0.57, z=4.11, p<0.001). The subgroup analyses revealed significant correlations between the -759 C/T polymorphism and AIWG in the Caucasian population (OR 0.33, 95% CI: 0.14 to 0.77, z=2.55, p=0.011), the Asian population (OR 0.31, 95% CI: 0.18 to 0.52, z=4.46, p<0.001), the patients with APDs administration (CT/TT/T vs CC/C: OR 0.63, 95% CI: 0.40 to 1.00, z=1.97, p=0.049) and the patients with atypical antipsychotic drug administration (CT/TT/T vs CC/C: OR 0.21, 95% CI: 0.09 to 0.47, z=3.83, p<0.001). The sensitivity analysis showed that the results were stable. Begg's test (after correction z=1.07, p=0.287) and Egger's test (t=-2.41, p=0.029) show that the included articles have no significant publication bias.
CONCLUSION
There is a significant genetic association between -759C/T and AIWG, and patients with T allele are less likely to have AIWG.
背景
抗精神病药物所致体重增加（AIWG）是精神分裂症患者停药的关键因素。多项研究表明，启动子区域的功能性多态性-759 C/T（rs3813929）可能与AIWG相关。
目的
评估精神分裂症患者使用抗精神病药物（APD）时，5-羟色胺受体2C基因（HTR2C）-759C/T多态性与AIWG之间的遗传关联。
方法
通过检索以下数据库确定符合条件的研究：PubMed、Embase、科学引文索引（Web of Science）、中国知网（CNKI）、维普资讯（VIP）、万方数据、中国生物医学文献数据库（CBM）和华艺数位图书馆（Airiti Library）。基于纽卡斯尔-渥太华量表（Newcastle-Ottawa Scale）评估研究质量。计算显性模式（CT/TT/T vs CC/C）下的合并比值比（OR）和95%置信区间（CI），并根据种族、抗精神病药物使用情况和性别进行亚组分析；所有统计分析均使用统计软件STATA V.12.0进行。
结果
我们的荟萃分析共纳入17项研究，涉及3170例精神分裂症患者。荟萃分析结果显示，-759 C/T多态性与AIWG之间的关联具有统计学意义（OR 0.34，95%CI：0.20至0.57，z=4.11，p<0.001）。亚组分析显示，-759 C/T多态性与白种人群（OR 0.33，95%CI：0.14至0.77，z=2.55，p=0.011）、亚洲人群（OR 0.31，95%CI：0.18至0.52，z=4.46，p<0.001）、使用APD的患者（CT/TT/T vs CC/C：OR 0.63，95%CI：0.40至1.00，z=1.97，p=0.049）以及使用非典型抗精神病药物的患者（CT/TT/T vs CC/C：OR 0.21，95%CI：0.09至0.47，z=3.83，p<0.001）中的AIWG存在显著相关性。敏感性分析表明结果稳定。Begg检验（校正后z=1.07，p=0.287）和Egger检验（t=-2.41，p=0.029）表明纳入的文章无显著发表偏倚。
结论
-759C/T与AIWG之间存在显著的遗传关联，携带T等位基因的患者发生AIWG的可能性较小。
