目标。目的:研究米诺环素在类风湿关节炎(RA)试验中对类风湿关节炎(RA)疾病严重程度的影响。在205例患者48周的随访中,174例(85%)患者的血液可用于人类白细胞抗原-DRB1和人类白细胞抗原-DQB1的分型,169例(82%)患者的血液可用于分型。基线侵蚀被用来评估疾病的严重性,而最后一次就诊时新的侵蚀可作为病情进展的指标。在基线时,腐蚀性疾病或类风湿因子状态的存在与类风湿表位的剂量(纯合子、杂合子、无)或所识别的特定等位基因之间没有关联。在最后一次访问中,在接受高加索安慰剂治疗而不接受米诺环素治疗的高加索患者中,观察到3个等位基因亚组(及其基因剂量)在发生新的糜烂方面存在梯度。多因素分析显示治疗组与人类白细胞抗原DR4表位相互作用。大约三分之二的非裔美国人患者没有类风湿表位。在一些高加索患者中,HL A-DRB1寡核苷酸分型可能有助于预测疾病的进展。我们的研究证实了该表位在非裔美国人类风湿关节炎患者中的出现频率很低。
Objective. To examine the effect of alleles encoding the “shared”/“rheumatoid” epitope on rheumatoid arthritis (RA) disease severity in patients who participated in the minocycline in RA (MIRA) trial.Methods. Of 205 patients with a week‐48 visit, blood was available for typing of HLA‐DRB1 and HLA‐DQB1 in 174 (85%) and successfully completed in 169 (82%). Baseline erosions were used to assess disease severity and new erosions at the last visit served as a proxy for progression.Results. At baseline, there was no association between the presence of erosive disease or rheumatoid factor status and the dose of rheumatoid epitope (homozygous, heterozygous, none) or the specific alleles identified. At the final visit, a gradient was observed for the 3 allelic subgroups (and their gene doses) in the occurrence of new erosions among the Caucasian placebotreated, but not the minocycline‐treated, patients. A treatment group/HLA‐DR4 epitope interaction was demonstrated in multivariate analyses. Approximately two‐thirds of African‐American patients did not have the rheumatoid epitope.Conclusion. HLA‐DRB1 oligotyping may be useful in predicting the progression of disease in some Caucasian patients. Our study corroborates the infrequency of the epitope among African‐American patients with RA.
