Studies investigating the association between HLA-DQB1 alleles and rheumatoid arthritis (RA) have reported conflicting results. The purpose of this study was to evaluate whether DQB1 alleles confer susceptibility to RA.
A comprehensive literature search up to May 2016 was conducted to identify case-control studies on the association of HLA-DQB1 alleles with RA. Pooled ORs with 95% CIs were used to assess the strength of association.
The literature indicates that HLA-DQB1 is associated with susceptibility to RA.
Frequencies of HLA-DQB1 alleles and phenotype in RA patients and healthy controls.
Fifteen studies with 1250 cases and 1621 controls were included in this meta-analysis. DQB1 alleles were associated with RA susceptibility. The frequencies of DQB106 were lower in RA (p-value for comparability=0.007, OR 0.726,95% CI 0.576 to 0.916; p0.004, OR 0.611,95% CI 0.438 to 0.852). The frequencies of DQB102 were lower in RA (p0.044, OR 0.731,95% CI 0.597 to 0.895). A higher frequency of DQB1*04 was observed in RA (p0.023, OR 1.604,95% CI 1.067 to 2.410).
This meta-analysis demonstrates that DQB102 and DQB106 may be negatively associated with RA. Conversely, DQB1*04 may confer susceptibility to RA.
关于研究人类白细胞抗原-DQB1（HLA-DQB1）等位基因与类风湿性关节炎（RA）之间关联的研究报告了相互矛盾的结果。本研究的目的是评估DQB1等位基因是否会使人易患RA。
进行了一项截至2016年5月的全面文献检索，以确定关于HLA-DQB1等位基因与RA关联的病例对照研究。采用合并比值比（OR）及95%可信区间（CI）来评估关联强度。
文献表明HLA-DQB1与RA易感性相关。
RA患者和健康对照中HLA-DQB1等位基因及表型的频率。
本荟萃分析纳入了15项研究，共1250例病例和1621例对照。DQB1等位基因与RA易感性相关。RA患者中DQB106的频率较低（可比性p值 = 0.007，OR 0.726，95%CI 0.576至0.916；p = 0.004，OR 0.611，95%CI 0.438至0.852）。RA患者中DQB102的频率较低（p = 0.044，OR 0.731，95%CI 0.597至0.895）。在RA患者中观察到DQB1*04的频率较高（p = 0.023，OR 1.604，95%CI 1.067至2.410）。
本荟萃分析表明，DQB102和DQB106可能与RA呈负相关。相反，DQB1*04可能使人易患RA。
