Aims: Rheumatoid arthritis is a chronic inflammatory condition that affects approximately 1% of the world's population. There are a wide number of guidelines and recommendations available to support the treatment of rheumatoid arthritis; however, the evidence used for these guidelines is predominantly based on studies in Caucasian subjects and may not be relevant for rheumatoid arthritis patients in the Asia-Pacific region. Therefore, the Asia Pacific League of Associations for Rheumatology established a Steering Committee in 2013 to address this issue. Materials and methods:The AGREE II instrument and the ADAPTE Collaboration framework were applied to systematically identify, appraise, synthesize, and adapt international rheumatoid arthritis guidelines for use in the Asia-Pacific region.Results: Forty rheumatoid arthritis treatment recommendations, based on evidence and expert opinion, were drafted and are presented in this report. Conclusion: The Asia Pacific of Associations for Rheumatology rheumatoid arthritis treatment recommendations are intended to serve as a reference for best practice management of rheumatoid arthritis in Asia-Pacific, focusing on local issues to ensure the delivery of basic care for these patients, and to improve their outcomes. In addition, the document will serve as a reference for national rheumatology associations in Asia-Pacific for developing guidelines in their respective countries.

AimTo update recommendations based on current best evidence concerning the treatment of rheumatoid arthritis (RA), focusing particularly on the role of targeted therapies, to inform clinicians on new developments that will impact their current practice.Materials and methodsA search of relevant literature from 2014 to 2016 concerning targeted therapies in RA was conducted. The RA Update Working Group evaluated the evidence and proposed updated recommendations using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, to describe the quality of evidence and strength of recommendations. Recommendations were finalized through consensus using the Delphi technique.ResultsThis update provides 16 RA treatment recommendations based on current best evidence and expert clinical opinion. Recommendations 1‐3 deal with the use of conventional synthetic disease‐modifying antirheumatic drugs. The next three recommendations (4‐6) cover the need for screening and management of infections and comorbid conditions prior to starting targeted therapy, while the following seven recommendations focus on use of these agents. We address choice of targeted therapy, switch, tapering and discontinuation. The last three recommendations elaborate on targeted therapy for RA in special situations such as pregnancy, cancer, and major surgery.ConclusionRheumatoid arthritis remains a significant health problem in the Asia‐Pacific region. Patients with RA can benefit from the availability of effective targeted therapies, and these updated recommendations provide clinicians with guidance on their use.

Objective To investigate the kinetics of hepatitis B virus (HBV) viral loads and HBV reactivation in rheumatoid arthritis (RA) patients undergoing therapy with tumour necrosis factor alpha (TNFα) inhibitors. Methods The authors investigated the virological, serological and biochemical evidence of HBV reactivation in 88 RA patients receiving anti-TNFα therapy. Levels of HBV surface (HBs) antigen (Ag), anti-HBV core (HBc)-IgG and anti-HBs antibody (Ab) were detected by electrochemiluminescence immunoassay, and viral loads were determined by real-time PCR assay. Results In a total of 88 HBcAb-positive patients, 18 (20.5%) patients were HBsAg-positive, 12 (13.6%) patients were HBsAg-negative/HBsAb-negative and 58 (65.9%) patients were HBsAg-negative/HBsAb-positive before starting anti-TNFα therapy. Among HBsAgpositive patients receiving anti-TNFα therapy, HBV reactivation was documented in none of 10 patients who received lamivudine pre-emptive therapy and serum viral loads signifi cantly decreased (mean±SEM, 153 860±80 120 IU/ml at baseline vs 313±235 IU/ ml after 12 months antiviral therapy, p<0.001), paralleling the decrease in serum aminotransferase levels. In contrast, fi ve (62.5%) of eight patients without antiviral prophylaxis developed HBV reactivation, viral loads signifi cantly increased after anti-TNFα therapy (9375±5924 IU/ml vs 49 710 000±40 535 000 IU/ml, p<0.001), and markedly declined after antiviral therapy (49 710 000±40 535 000 IU/ml vs 6382±2424 IU/ml, p<0.001). Baseline viral loads were detectable in four (33.3%) of 12 patients who had HBsAg-negative/HBsAbnegative status, and one developed HBV reactivation after anti-TNFα therapy. Conclusion HBV reactivation can occur in both HBsAgpositive and HBsAg-negative/HBcAb-positive patients with detectable HBV DNA, so-called occult HBV infection, during anti-TNFα therapy. Antiviral prophylaxis may effectively reduce HBV reactivation in HBsAg-positive RA patients undergoing anti-TNFα therapy.It is estimated that more than one-third of the world's population has been infected with the hepatitis B virus (HBV) and that 75% of these people live in southeast Asia and the western Pacifi c regions. 1 Taiwan is an endemic area of HBV infection, with an HBV surface antigen (HBsAg) carrier rate of 15-20% and HBV core antibody (HBcAb) positive rate of 80-90%. 2 3

T helper type 17 (Th17) cells, a novel distinct subset of Th cell, can secrete interleukin (IL)-17 in humans. Although recent data suggest that Th17 cells and IL-17 play an important role in the pathogenesis of lupus nephritis (LN), the expression of Th17-related cytokines in the kidneys of SLE patients has not been studied in detail. In the present study, we investigated circulating Th17-cell frequencies using flow cytometry and serum Th17-related cytokine levels by enzyme-linked immunosorbent assay (ELISA) in 24 LN patients (17 patients with class IV and seven patients with class V) and 12 healthy controls. We also investigated glomerular Th17-related cytokine expression in LN patients and minimal change nephropathy (MCN) patients using immunohistochemistry. Our results showed significantly higher median frequencies of circulating Th17 cells in LN patients (0.68%) than in healthy controls (0.12%, p < 0.001). Serum levels of IL-17, IL-6 and IL-23 were significantly higher in LN patients (median 7.26, 232.60 and 37.01 pg/ml, respectively) than in healthy controls (median 0.82, 34.60 and 7.42 pg/ml, respectively; all p < 0.001). Circulating Th17-cell frequencies were positively correlated with SLEDAI, renal SLEDAI and histological activity index, the degree of cellular crescent and endocapillary proliferation. Significantly higher levels of glomerular IL-17 and IL-23 expression were observed in renal biopsies from class IV LN patients as compared to those from MCN patients and normal controls. Glomerular IL-17 and IL-23 expression levels were positively correlated with renal SLEDAI and histological activity index for LN patients. Our results suggest the potential role of the IL-23/Th17 axis in the intra-renal inflammation of SLE.
