    OBJECTIVE: To investigate the efficacy and safety of hydroxychloroquine (HCQ) in patients with rheumatoid arthritis (RA). METHODS: Patients with active RA, despite conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), were recruited. HCQ was administered for 24 weeks, in addition to prior treatment. The primary endpoint was the proportion of American College of Rheumatology (ACR) 20 achievement at week 24, compared to that of a propensity score matched historical control group. RESULTS: Sixty patients were enrolled and administered HCQ. We also identified 276 patients as candidates for the historical control group. Propensity score matching yielded 46 patients in each group. The proportion of ACR20 achievements at week 24 was significantly higher in the HCQ group than that in the control group (54.4% vs. 28.3%, P = 0.007). The proportion of ACR50 and ACR70 achievement at week 24 were also higher in the HCQ group than those in the control group (ACR50, 30.4% vs. 4.3%, P = 0.006; ACR70, 17.4% vs. 0%, P = 0.005). Neither hydroxychloroquine retinopathy nor any new safety signal was observed during the study. CONCLUSION: The addition of HCQ to csDMARDs was effective, with no new safety signal in patients with RA.

    Background: The selection and categorisation of laboratory tests in disease activity measures used within systemic lupus erythematosus (SLE) trial endpoints lack strong evidence. We aimed to determine whether longitudinal improvements in routinely measured laboratory tests are associated with measures of clinical improvement in patients with baseline active SLE. Methods: We included patients from a multicentre longitudinal cohort (recruited between May 1, 2013, and Dec 31, 2019) with active SLE (SLEDAI-2K ≥6) coinciding with an abnormality in at least one of 13 routine laboratory tests, at a visit designated as baseline. At 12 months, we analysed associations between thresholds of improvement in individual laboratory test results, measured as continuous variables, and five clinical outcomes using logistic regression. Primary outcomes were damage accrual and lupus low disease activity state (LLDAS), and secondary outcomes were modified SLE responder index (mSRI), physician global assessment (PGA) improvement of at least 0·3, and flare. Findings: We included 1525 patients (1415 [93%] women and 110 [7%] men, 1328 [87%] Asian ethnicity) in separate subsets for each laboratory test. The strongest associations with LLDAS and damage protection were seen with improvements in proteinuria (complete response: adjusted odds ratio [OR] 62·48, 95% CI 18·79–208·31 for LLDAS, OR 0·22, 95% CI 0·10–0·49 for damage accrual), albumin (complete response: adjusted OR 6·46, 95% CI 2·20–18·98 for LLDAS, OR 0·42, 95% CI 0·20–1·22 for damage accrual), haemoglobin (complete response: adjusted OR 1·97, 95% CI 1·09–3·53 for LLDAS, OR 0·33, 95% CI 0·15–0·71 for damage accrual), erythrocyte sedimentation rate (complete response: adjusted OR 1·71, 95% CI 1·10–2·67 for LLDAS, OR 0·53, 95% CI 0·30–0·94 for damage accrual), and platelets (complete response: adjusted OR 4·82, 95% CI 1·54–15·07 for LLDAS, OR 0·49, 95% CI 0·20–1·19 for damage accrual). Improvement in serological tests were mainly associated with PGA and mSRI. White cell and lymphocyte count improvements were least predictive. Interpretation: Improvements in several routine laboratory tests correspond with clinical outcomes in SLE over 12 months. Tests with the strongest associations were discrepant with laboratory tests included in current trial endpoints, and associations were observed across a range of improvement thresholds including incomplete resolution. These findings suggest the need to revise the use of laboratory test results in SLE trial endpoints. Funding: Abbvie.

    Background: Treat-to-target goals for patients with systemic lupus erythematosus (SLE) have been validated to protect against organ damage and to improve quality of life. We aimed to investigate the association between lupus low disease activity state (LLDAS) and remission and risk of mortality in patients with SLE. We hypothesised that LLDAS has a protective association with mortality risk. Methods: In this prospective, multinational, longitudinal cohort study, we used data from patients with SLE in the Asia Pacific Lupus Collaboration cohort collected between May 1, 2013, and Dec 31, 2020. Eligible patients were adults (aged ≥18 years) who met either the 1997 American College of Rheumatology modified classification criteria for SLE or the 2012 Systemic Lupus International Collaborating Clinics classification criteria. The primary outcome was all-cause mortality, and LLDAS, remission, and variations of remission with lower glucocorticoid thresholds were the primary exposure variables. Survival analyses were used to examine longitudinal associations between these endpoints and risk of mortality. This study is registered with ClinicalTrials.gov, NCT03138941. Findings: Among a total of 4106 patients in the cohort, 3811 (92·8%) patients were included in the final analysis (median follow-up 2·8 years [IQR 1·0–5·3]; 3509 [92·1%] women and 302 [7·9%] men), of whom 80 died during the observation period (crude mortality rate 6·4 deaths per 1000 person-years). LLDAS was attained at least once in 43 (53·8%) of 80 participants who died and in 3035 (81·3%) of 3731 participants who were alive at the end of the study (p<0·0001); 22 (27·5%) participants who died versus 1966 (52·7%) who were alive at the end of the study attained LLDAS for at least 50% of observed time (p<0·0001). Remission was attained by 32 (40·0%) of 80 who died and in 2403 (64·4%) of 3731 participants who were alive at the end of the study (p<0·0001); 14 (17·5%) participants who died versus 1389 (37·2%) who were alive at the end of the study attained remission for at least 50% of observed time (p<0·0001). LLDAS for at least 50% of observed time (adjusted hazard ratio 0·51 [95% CI 0·31–0·85]; p=0·010) and remission for at least 50% of observed time (0·52 [0·29–0·93]; p=0·027) were associated with reduced risk of mortality. Modifying the remission glucocorticoid threshold (<5·0 mg/day prednisolone) was more protective against mortality than current remission definitions (0·31 [0·12–0·77]; p=0·012), and glucocorticoid-free remission was the most protective (0·13 [0·02–0·96]; p=0·046). Interpretation: LLDAS significantly reduced the risk of mortality in patients with SLE. Remission did not further reduce the risk of mortality compared with LLDAS, unless lower glucocorticoid thresholds were used. Funding: The Asia-Pacific Lupus Collaboration received funding from Janssen, Bristol Myers Squibb, Eli Lilly, and UCB for this study.

    全身性エリテマトーデスは、繰り返す再燃や臓器障害の蓄積が課題である。現在、ステロイドに代わる適切な治療薬の選択や予後予測のバイオマーカー、個別化医療の方法が模索されている。研究代表者は末梢血および尿中プロテオミクス解析からSLEの疾患活動性と相関する分子を多数見出している。本研究では、ELISAでのバリデーション、エクソーム解析、経時的な臨床特徴(障害臓器別、治療前後比較)と統計解析、末梢血免疫フェノタイピングおよびソーティング単球・リンパ球を用いたin vitro機能解析などを組み合わせることで、新規の病態関連分子の同定を行う。
    初めに、活動性全身性エリテマトーデス(SLE)の予後を規定する指標の構築を目的として、低疾患活動性状態(LLDAS; Lupus Low Disease Activity Score)達成の時期を検討した。活動性SLEにおいて寛解導入療法開始後12ヶ月以内のLLDASを達成することが、臨床的アウトカム(重症再燃低下、ステロイド積算量低値、期間中のLLDAS達割合高値)と関連することを示した。次に活動性SLEにおける寛解導入療法開始後の末梢血免疫細胞の変動を特定した。特にシクロホスファミド治療群ではCD4陽性T細胞全体、主にナイーブCD4陽性T細胞が有意に減少し、B細胞全体及びナイーブB細胞が有意に低下した一方、ミコフェノール酸モフェチル治療群ではナイーブCD4陽性T細胞とナイーブB細胞の変動は見出せず、活性化CD4陽性T細胞、活性化CD8陽性T細胞、plasmablast、plasma細胞、樹状細胞割合の低下が見出された。すなわち、寛解導入療法として主に用いられる2剤で変動する末梢血免疫細胞の種類が異なることを示した。さらに、臨床的アウトカムとの関連因子として、末梢血Plasmablastの変動が治療予後と関連することを見出し、12ヶ月以内LLDAS達成と関連する細胞分画の変動を免疫抑制剤ごと見出すことができた。臓器特異的な検討としてループス腎炎に着目した。臨床的に深い寛解状態と関連する末梢血免疫細胞としてT細胞、単球、樹状細胞、形質細胞分画が見出された。さらに、腎生検で得た組織学的な検討を行い、尿中タンパク質の解析を行い、活動性所見および間質病変所見と関連する病態として種々のパスウェイが関連することを示した。
