OBJECTIVE:To investigate whether abatacept (ABA) causes more adverse events (AE) than conventional synthetic disease-modifying antirheumatic drugs (csDMARD) after orthopedic surgery in patients with rheumatoid arthritis (RA). METHODS:A retrospective multicenter nested case-control study was performed in 18 institutions. Patients receiving ABA (ABA group) were matched individually with patients receiving csDMARD and/or steroids (control group). Postoperative AE included surgical site infection, delayed wound healing, deep vein thrombosis or pulmonary embolism, flare, and death. The incidence rates of the AE in both groups were compared with the Mantel-Haenszel test. Risk factors for AE were analyzed by logistic regression model. RESULTS:A total of 3358 cases were collected. After inclusion and exclusion, 2651 patients were selected for matching, and 194 patients in 97 pairs were chosen for subsequent comparative analyses between the ABA and control groups. No between-group differences were detected in the incidence rates of each AE or in the incidence rates of total AE (control vs ABA: 15.5% vs 20.7% in total, 5.2% vs 3.1% in death). CONCLUSION:Compared with csDMARD and/or steroids without ABA, adding ABA to the treatment does not appear to increase the incidence rates of postoperative AE in patients with RA undergoing orthopedic surgery. Large cohort studies should be performed to add evidence for the perioperative safety profile of ABA.
目的: 探讨阿巴西普 (ABA) 在类风湿关节炎 (RA) 患者骨科手术后是否比常规合成改善病情抗风湿药 (csDMARD) 引起更多的不良事件 (AE)。 方法: 在 18 家机构进行回顾性多中心巢式病例对照研究。接受 ABA 的患者 (ABA 组) 与接受 csDMARD 和/或类固醇的患者 (对照组) 单独匹配。术后 AE 包括手术部位感染、伤口愈合延迟、深静脉血栓形成或肺栓塞、复发和死亡。用 Mantel-Haenszel 试验比较两组 AE 的发生率。采用 logistic 回归模型分析 AE 的危险因素。 结果: 共收集病例 3358 例。纳入和排除后，选择 2651 例患者进行匹配，选择 97 对中的 194 例患者进行随后的 ABA 和对照组之间的比较分析。各组 AE 发生率或总 AE 发生率均未检测到组间差异 (对照组 vs ABA: 15.5% vs 20.7%，死亡 5.2% vs 3.1%)。 结论: 与无 ABA 的 csDMARD 和/或类固醇相比，在治疗中加入 ABA 似乎不会增加 RA 骨科手术患者术后 AE 的发生率。应进行大型队列研究，为 ABA 的围手术期安全性提供证据。
METHODS:Rheumatoid arthritis (RA) is an autoimmune disease which can lead to progressive and functional disability. Literature data suggest that some inflammatory proteins are dysregulated in RA patients and its genetic polymorphisms may contribute to the aetiology and pathogenesis of disease in different ethnic groups. Polymorphisms in and genes were studied in different populations with RA, but the analysis indicated contradictory results. Thereby, we hypothesised that polymorphisms in these genes could have a combined effect on susceptibility to and severity of disease. We evaluated the +3953 C/T (rs1143634), -137 G/C (rs187238), -94 ins/del ATTG (rs28362491) and +874 T/A (rs2430561) polymorphisms in the northeastern Brazilian population. Peripheral blood samples were collected and DNA extraction was conducted. The polymorphisms were evaluated by RFLP and ARMS-PCR. An association was observed in rs1143634 which showed a protective effect against development of RA in carriers of the T allele (OR = 0.58; 95% CI 0.36-0.92; = .020). In addition, we found an association among genotypes of the rs1143634 with the HAQ index ( = .021) and rs2430561 with DAS28 ( = .029) and CDAI ( = .029). In relation to combined effects of these SNPs (C/C to rs1143634, G/G to rs187238, I/I to rs28362491 and AA to rs2430561) we found a significant association with decreased functional disability (HAQ index < .001) and ESR ( = .034), indicating a lower disease activity in carriers of these genotypes. GLM analysis confirmed these associations (HAQ ( = 5.497; < .001) and ESR ( = 2.727; = .032)). Our analysis indicated that in the studied population +3953 C/T (rs1143634), -137 G/C (rs187238), -94 ins/del ATTG (rs28362491) and +874 T/A (rs2430561) polymorphisms can together contribute to RA severity although they do not individually influence the disease.
METHODS:ZNF804a and CDK1 genes code for proteins involved in inflammatory pathways. This study aimed to investigate the correlation of ZNF804a and CDK1 expression profiles in RA with the activity and the severity of the disease and to assess their association with inflammatory reactions in the Egyptian RA patients. ZNF804a and CDK1 expression profiles were assessed using quantitative PCR (qRT-PCR). Clinical and laboratory parameters were evaluated. ZNF804a expression was down-regulated by 0.177-fold while CDK1 expression was up-regulated to 3.29-fold in RA patients compared with healthy controls ( < .001). ZNF804a down-regulation was negatively correlated with CRP, RF, disease activity score of 28 joints (DAS) using CRP (DAS-CRP) and TNF-α. CDK1 overexpression was correlated with IFN-1 and ACPA in RA patients. ZNF804a and CDK1 genes are implicated in RA pathogenesis due to their influences on TNF-α and IFN-1 which contribute to inflammation in RA patients.
METHODS:OBJECTIVES:We sought to confirm in very early rheumatoid arthritis (ERA) a much greater superiority (30%) of first-line etanercept+methotrexate (ETN+MTX) over treat-to-target MTX (MTX-TT) than previously reported in ERA (14%); and explore whether ETN following initial MTX secures a comparable response to first-line ETN+MTX. METHODS:Pragmatic, open-label, randomised controlled trial of treatment-naïve ERA (≤12 months symptom), Disease Activity Score 28 joint (DAS28)-erythrocyte sedimentation rate (ESR) ≥3.2, rheumatoid factor (RF)+/-anticitrullinated peptide antibody (ACPA) positive or ultrasound power Doppler (PD) if RF and ACPA negative. Subjects were randomised 1:1 to ETN+MTX; or MTX-TT, escalated to ETN if week 24 DAS28-ESR ≥2.6 and intramuscular corticosteroid at protocolised time points. Primary endpoint of week 48 DAS28ESR remission with clinical and imaging secondary endpoints. RESULTS:We randomised 120 patients, 60 to each arm (71% female, 73% RF/84% ACPA positive, median (IQR) symptom duration 20.3 (13.1, 30.8) weeks; mean (SD) DAS28 5.1 (1.1)). Remission rates with ETN+MTX and MTX-TT, respectively, were 38% vs 33% at week 24; 52% vs 38% at week 48 (ORs 1.6, 95% CI 0.8 to 3.5, p=0.211). Greater, sustained DAS28-ESR remission observed with ETN+MTX versus MTX-TT (42% and 27%, respectively; p=0.035). PD was fully suppressed by week 48 in over 90% in each arm. Planned exploratory analysis revealed OR 2.84, 95% CI 0.8 to 9.6) of achieving remission after 24 weeks of ETN administered first line compared with administered post-MTX. CONCLUSIONS:Compared with remission rates typically reported with first-line tumour necrosis factor inhabitor+MTX versus MTX-TT, we did not demonstrate a larger effect in very ERA. Neither strategy conferred remission in the majority of patients although ultrasound confirmed local inflammation suppression. Poorer ETN response following failure of MTX-TT is also suggested.Trial registration numberNCT02433184.
