RESUMO
OBJECTIVES: To evaluate the status of the global standardization of, and prefectural differences in, systematic lupus erythematosus (SLE) treatments in Japan. METHODS: The Japanese National Database of Health Insurance Claims and Specific Health Checkups (NDB Japan) was used. A patient with SLE was defined as having a disease with ICD10 code M321 or M329 between April 2019 and March 2020, for which oral corticosteroids (OCS), immunosuppressive agents or biologic agents were prescribed at least once during a given month. SLE treatments were evaluated by treatment center type and prefecture. RESULTS: In total, 74,277 patients met the definition of SLE. The SLE prevalence was 60 per 100,000 (range: 47 - 102 per 100,000 by prefecture). Nationwide, 79.4% of the patients (range: 52.1% - 93.3% by prefecture) visited a specialized treatment center (STC); 37.4% (range: 26.4% - 51.3% by prefecture) received only OCS, with fewer of these patients visiting a STC than a non-STC (34.8% and 49.7%, p<0.001); and 21.4% (range: 10.7% - 35.0%) received HCQ, with more of these patients visiting a STC than a non-STC (23.0% and 13.5%; p<0.001). CONCLUSIONS: NDB Japan demonstrated delayed global standardization of, and prefectural disparity in, SLE treatments in Japan.
RESUMO
OBJECTIVE: We compared the incidence rates of hospitalized infections (HIs) between tocilizumab (TCZ) and other biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in adults aged ≥75 years with rheumatoid arthritis (RA). METHODS: We used a Japanese claims database from Medical Data Vision Co., Ltd (Tokyo, Japan) to perform a retrospective longitudinal population-based study in patients with RA who were prescribed b/tsDMARDs between 2014 and 2019. We calculated adjusted risk ratios (aRRs) for HIs in three age groups (<65, ≥65 and <75, and ≥75 years). RESULTS: Of 5506 patients, 2265 (41.1%) were <65 years, 1709 (31.0%) were 65-74 years, and 1532 (27.8%) were ≥75 years. Crude incidence rates (/100 person-years) of HIs were 3.99, 7.27, and 10.77, respectively. In the oldest group, aRRs (95% confidence interval) for HIs (b/tsDMARDs versus TCZ) were as follows: etanercept, 2.40 (1.24-4.61); adalimumab, 1.90 (0.75-4.83); golimumab, 1.21 (0.66-2.23); and abatacept, 0.89 (0.49-1.62). In the other age groups, the noticeable difference was a lower aRR of etanercept versus TCZ in the youngest group (0.30, 0.11-0.85). CONCLUSION: In patients with RA aged ≥75 years, b/tsDMARDs have a similar risk of HIs to tocilizumab except for etanercept.

Objectives We aimed to assess the unmet medical needs of young adult patients with juvenile idiopathic arthritis by evaluating real-world treatment data. Methods We analyzed data on juvenile idiopathic arthritis in the 20-29 age group from the National Database of Designated Incurable Diseases of Japan, which records severe cases or those requiring high-cost medical care registered between April 2018 and March 2020. Results Overall, 322 patients with juvenile idiopathic arthritis transitioning to adulthood were included. A high frequency of methotrexate use was observed among all juvenile idiopathic arthritis subtypes. The frequency of methotrexate use at registration was significantly higher in patients with rheumatoid factor-positive polyarthritis and those with oligoarthritis or polyarthritis than in those with systemic arthritis. The historical use percentage of any biological disease-modifying antirheumatic drug was ≥85% for all juvenile idiopathic arthritis subtypes. The proportion of patients with ≥2 biological disease-modifying antirheumatic drug prescriptions was significantly higher in patients with rheumatoid factor-positive polyarthritis than in those with systemic arthritis. Conclusions High-cost drugs were necessary for many patients with juvenile idiopathic arthritis transitioning to young adulthood and registered in the database. Further studies on the medical interventions and support for these patients are needed.
RESUMO
OBJECTIVES: To explore patient-reported outcomes (PROs) related to quality of life (QOL) in patients with rheumatoid arthritis (RA) who achieved clinical remission. METHODS: In the Institute of Rheumatology, Rheumatoid Arthritis dataset, RA patients >18 years old who met the simplified disease activity index (SDAI) remission criteria in April 2017 were enrolled in this analysis. Pain-visual analogue scale (pain-VAS) (0-100 mm), patient's global assessment of disease activity (Pt-GA; 0-100 mm), Japanese version of the Health Assessment Questionnaire, duration of morning joint stiffness, and fatigue [Checklist Individual Strength 8R (CIS)] were the tools used to evaluate PROs. To assess the contribution of each PRO to the European QOL-5 Dimensions-5 Level (EQ-5D-5L) score, an analysis of variance was conducted. RESULTS: Among the 2443 patients with remission, the mean EQ-5D-5L was 0.9. The mean pain-VAS and Pt-GA were 7.2 and 7.4, respectively. Factors that significantly contributed to the EQ-5D-5L were pain-VAS (48.8%), CIS score (18.1%), and Pt-GA (15.6%). Around 82.5% of the variance in EQ-5D-5L was explained by the three PROs. CONCLUSIONS: This study demonstrated that pain-VAS, CIS, and Pt-GA were significant contributors to the EQ-5D-5L score in patients with RA who achieved the simplified disease activity index remission criteria.

OBJECTIVES: To explore the patient-reported outcomes (PROs) associated with work productivity and activity impairment (WPAI) in patients with rheumatoid arthritis (RA) in clinical remission. METHODS: We enrolled patients with RA ≥18 years and with a simplified disease activity index ≤3.3 from the Institute of Rheumatology, Rheumatoid Arthritis data set collected in October 2017. The pain-visual analogue scale, patients' global assessment visual analogue scale (VAS), Japanese version of the Healthcare Assessment Questionnaire (J-HAQ) Disability Index, and duration of morning joint stiffness were selected as the PROs. To evaluate work productivity and activity, the WPAI for RA instrument (WPAI-RA) was used. To assess the contribution of each PRO to the WPAI-RA score, an analysis of variance model was constructed. RESULTS: The mean age of the 2614 patients was 62.4 years; 85.1% were female. Median values of the WPAI-RA score were 1.1% for absenteeism, 6.5% for presenteeism, 7.4% for work impairment, and 10.2% for activity impairment. Morning joint stiffness contributed the most to absenteeism (18.0%), while pain-VAS contributed the most to presenteeism (57.4%), work productivity loss (51.1%), and daily activity impairment (53.7%). J-HAQ was the second most contributing factor to presenteeism (17.4%), work productivity loss (16.3%), and daily activity impairment (26.0%). CONCLUSIONS: The pain-VAS and J-HAQ highly contributed to WPAI in patients with RA in clinical remission.

OBJECTIVE: We conducted a nationwide epidemiological study to estimate the number of patients with Takayasu arteritis (TAK) and giant cell arteritis (GCA) in Japan and to describe the clinical characteristics of these patients. METHODS: The first survey was designed to estimate the number of patients with TAK and GCA who were treated at medical institutions in Japan in 2017. The second survey was designed to collect data on the clinical characteristics of the patients who were reported in the first survey. RESULTS: Of the 3495 institutions selected for the first survey, 1960 (56.1%) responded. The number of patients with clinically diagnosed TAK and GCA was estimated to be 5320 (95% confidence interval, 4810-5820) and 3200 (95% confidence interval, 2830-3570), respectively. Aortic regurgitation was reported in 35% of patients with TAK, and eye-related comorbidities were observed in 30.4% of patients with GCA. The common carotid and internal carotid arteries were the most frequently involved in patients with TAK (62.7%). Subclavian artery lesions and thoracic or abdominal aorta lesions were reported in 31% and 42.6% of patients with GCA, respectively. CONCLUSIONS: The number of patients with TAK and GCA was estimated simultaneously, and significant differences in clinical characteristics were observed between the two diseases.

OBJECTIVES: To characterize the treatments for rheumatoid arthritis (RA) among institution types and prefectures in Japan. METHODS: Using the National Database of Health Insurance Claims and Specific Health Checkups of Japan in the 2017 fiscal year, we investigated disease-modifying antirheumatic drug (DMARD) and oral corticosteroid prescription trends across 825 thousand RA patients. These data were compared between specialized and non-specialized institutions and by prefecture. RA specialized institutions (SIs) were defined as either institutions registered in the rheumatology training program at the Japan College of Rheumatology or institutions where board-certified rheumatologists were employed. RESULTS: The overall percentage of patients who never visited an SI was 31.8% and increased with age (16-29 years old = 15.6%; ≥80 years = 42.8%). In twelve prefectures (25.5%), the proportions of patients who never visited an SI were at least 10% higher than the overall average. The proportions of patients who only visited SIs and were prescribed methotrexate and biological DMARDs were ranged from 51.9-72.9% and 19.5-33.2%, respectively. However, those of patients who had never visited an SI and were prescribed those medications were 44.0-71.6% and 7.2-28.0%, respectively. CONCLUSIONS: This is the first study evaluating the trends in RA treatments by prefecture and institution specialty by using the NDB Japan. Opportunities of patients with RA for visiting SI was unevenly distributed in Japan, affecting some aspects of treatment provided.

OBJECTIVES: Immunosuppressive therapy is the mainstay of treatment for child-onset systemic lupus erythematosus (cSLE). Since epidemiological data on Japanese cSLE patients are not available, we evaluated the trends in how treatment choices have changed over time in Japan. METHODS: Using the Japanese health insurance database provided by Medical Data Vision Co., Ltd, we identified cSLE patients and evaluated changes in the use of corticosteroids and immunosuppressive medications and maximum daily doses of prednisolone from 2009 to 2018. RESULTS: Of 182 cSLE patients, 86% were female, and the median age was 14 years. Oral prednisolone was used in more than 97% of cSLE patients during the study period, and the median of the maximum daily dose in each patient decreased over time. Intravenous cyclophosphamide was used less frequently after 2016, while mycophenolate mofetil and hydroxychloroquine were used frequently after 2016. The use of mizoribine reduced after 2014, whereas the other immunosuppressive medications showed no significant change over time; the use of biological agents was very limited. CONCLUSIONS: Oral prednisolone was the mainstay of treatment for cSLE, and the maximum daily dose has reduced over the past decade. The most frequently prescribed immunosuppressive therapy has shifted to mycophenolate mofetil over time.

OBJECTIVES: To investigate the risk factors and clinical characteristics of lymphoproliferative disorder (LPD) in Japanese patients with rheumatoid arthritis (RA). METHODS: We enrolled patients with RA aged ≥20 years who visited the participating hospitals between April 2011 and July 2011. We investigated the risk factors for LPD using a Cox proportional hazard model and described pathological features and vital prognosis of LPD in patients with RA. RESULTS: We enrolled 9815 patients with the following characteristics at baseline: female 79.4%, median age 63 years; median disease duration 7 years; median DAS28-CRP (3) 3.1; prevalence of MTX use 60.0%. Sixty-eight patients (0.69%) developed LPD in 3-year observation period. Multivariable analysis showed that age by decade (hazard ratio [95% confidence interval], 1.47 [1.18-1.85]) and MTX use at baseline (2.35 [1.25-4.42] for ≤8 mg/week, 4.39 [2.07-9.32] for >8 mg/week versus non-use) were significant risk factors of LPD. Of 55 patients with pathological diagnosis, diffuse large B cell lymphoma was the most frequent (54%). The 5-year mortality of LPD was 24%. The major cause of death was lymphoma (81%). CONCLUSION: This nationwide study revealed risk factors, clinical characteristics, and prognosis of LPD in the largest number of Japanese patients with RA.

OBJECTIVES: To evaluate the differences in patients' population and efficacy/effectiveness of biological disease-modifying antirheumatic drugs (bDMARDs) between randomized controlled trials (RCTs) and clinical practice in patients with rheumatoid arthritis. METHODS: We reviewed inclusion criteria in Phase II or III RCTs of bDMARDs conducted in Japan. The Institute of Rheumatology, Rheumatoid Arthritis study participants during the period when each RCT was conducted (Cohort A) and new bDMARD users at our institute in 2016 (Cohort B) were assessed for the fulfilment of the inclusion criteria. The effectiveness of bDMARDs in our cohort and their efficacy in RCTs were compared using the inverse-variance method. RESULTS: Nineteen RCTs were selected. The mean proportions of patients fulfilling all inclusion criteria of each RCT in Cohorts A and B were 2.3% and 7.6%, respectively. The pooled proportion ratios (95% confidence interval) for achieving the American College of Rheumatology 20 (ACR20), ACR50, ACR70, and disease activity score 28 remission in non-eligible cases for eight RCTs versus all corresponding RCTs were 0.38 (0.30-0.51), 0.41 (0.30-0.57), 0.54 (0.35-0.82), and 1.28 (1.10-1.56), respectively. CONCLUSIONS: Few rheumatoid arthritis patients fulfilled the inclusion criteria of the RCTs in clinical settings. There was a difference in the efficacy/effectiveness of bDMARDs between RCTs and clinical practice.

OBJECTIVE: To compare the risk of hospitalized infection (HI) between users and non-users of hydroxychloroquine (HCQ) in systemic lupus erythematosus (SLE). METHODS: Using claims data, patients were defined as SLE cases by the following criteria: 1) they had at least one SLE diagnostic code; 2) they had a prescription for specific drugs, including corticosteroids, steroid pulse therapy, and immunosuppressive drugs; and 3) they were at least 16 years old between September 2015 and July 2017 (n = 17,483). The SLE cases with at least one prescription for HCQ were defined as the HCQ group (n = 1,431), while the others were defined as the non-HCQ group. Among the SLE cases, propensity score-matched cases were observed for 1 year (n = 1,095 in each group). RESULTS: The median age and proportion of female patients in both groups were about 42 years and 88%, respectively. The proportions of cases with HIs were similar (HCQ group, 4.5%; non-HCQ group, 5.6%; p = 0.240, McNemar test). The hazard ratio of the HCQ group for HIs after adjusting for patients' characteristics was not significant at 0.9 (0.6-1.3). CONCLUSION: The use of HCQ was not associated with a risk of HIs in patients with SLE.

Objective: To evaluate the risk of hospitalized infection (HI), cardiovascular disease (CVD), stroke, and fracture in rheumatoid arthritis (RA) patients compared with non-RA patients using the Japanese health insurance database. Method: Among individuals aged ≥18 years, RA cases were defined to have one RA diagnostic code and receiving ≥1 disease-modifying antirheumatic drug between 2005 and 2013 (n = 6,712). Age-, sex-, calendar year of the observation start-, and observation length-matched non-RA cases were selected at 1:5 (n = 33,560). Hazard ratios (HRs) were calculated using the time-dependent Cox regression analysis. Results: Median age of the patients was 52.0 years. The incidence rates of HI, CVD, and fracture in the RA group were 2.42/100 person-years (PY), 4.94/1,000 PY, and 10.59/1,000 PY. The crude incidence rate ratios (95% CI) (RA vs. non-RA) for HI, CVD, and fracture were 2.47 (2.20-2.77), 1.89 (1.49-2.41), and 3.35 (2.80-4.02). The adjusted HR (95% CI) (RA vs. non-RA) was significantly elevated (HI, 1.74 [1.52-1.99], CVD, 1.38 [1.04-1.85], and fracture, 1.88 (1.54-2.31)]. Conclusion: The relatively young RA population had significantly higher risks of these complications than the non-RA, indicating importance of prevention of them even at young ages in clinical settings.

OBJECTIVE: To evaluate association of clinical remission at month 6 with functional and structural remissions at month 12 during abatacept treatment in patients with rheumatoid arthritis (RA). METHODS: This 12-month prospective, multicenter cohort study enrolled 168 patients with RA who started abatacept. Outcomes were assessed using composite measures, quality of life indices, and the van der Heijde-modified total Sharp score (mTSS). The logistic regression analysis was applied to identify factors associated with outcomes and their odds ratios (OR) with 95% confidence interval (95% CI). RESULTS: At month 6 and 12, 21.4% and 26.2% of the patients achieved Simplified Disease Activity Index (SDAI) remission (SDAI <3.3), and 40.6% and 41.7% achieved Health Assessment Questionnaire-Disability Index (HAQ-DI <0.5) remission. Among 129 patients whose mTSS progression was evaluated at month 12, 83 (64.3%) achieved structural remission (ΔmTSS ≤0.5 for 12 months). SDAI remission at month 6 was identified as a significant predictor of both functional (OR, 3.732; 95% CI, 1.328-10.489) and structural remissions (OR, 4.301; 95% CI, 1.298-14.243) at month 12 after adjusting for covariates. CONCLUSIONS: Aiming for SDAI remission at month 6 is an appropriate strategy to obtain good functional and structural outcomes at month 12.

OBJECTIVE: To verify predictive validity of simplified disease activity index (SDAI) remission for subsequent functional and structural outcomes in real-world clinical settings under a treat-to-target strategy (T2T). METHODS: In this multicenter, prospective cohort study, T2T was implemented in rheumatoid arthritis (RA) patients with moderate-to-high disease activity. SDAI or clinical disease activity index (CDAI) was assessed every 12 weeks, and treatment was adjusted to achieve clinical remission or low disease activity (LDA). Multivariate logistic regression models were used to examine the associations of SDAI remission (≤3.3) at week 24 with the health assessment questionnaire-disability index (HAQ-DI) ≤ 0.5 or with the delta van der Heijde-modified total Sharp score (ΔvdH-mTSS) Assuntos

RESUMO
OBJECTIVES: To investigate and compare the risk for malignancy in rheumatoid arthritis (RA) patients treated with biologics in Japan to the general population. METHODS: Data for 14,440 patients from 335 institutions who were given infliximab, etanercept, adalimumab, golimumab, tocilizumab, or abatacept were retrieved from the SafEty of biologics in Clinical Use in Japanese patients with RhEumatoid arthritis (SECURE) database. RESULTS: We identified 333 incidents of malignancies in 320 patients during 49,320 patient-years (PY). The age- and sex-standardized incidence rate (ASR) (95% confidence interval [CI]) for overall malignancy of the SECURE cohort was 313.9/10(5) PY (271.4-361.3), and the standardized incidence rate ratio (SIR) (95% CI) was 0.745 (0.667-0.826). The ASR was decreased compared to the estimated incidence rate of malignancies in the Japanese general population (462.4/10(5) PY). The SIRs for site-specific nonhematopoietic malignancies of the SECURE cohort were not significantly elevated compared to the Japanese general population. A significant increase of SIR for malignant lymphoma (6.183, 95% CI, 4.809-7.643) was found in the SECURE cohort, similar to or slightly higher than the SIR previously reported from Japanese cohorts for RA patients. CONCLUSIONS: Continued vigilance with larger numbers of patients, longer observation periods, and inclusion of different biologics are recommended.

OBJECTIVE: To reveal any association between rheumatoid arthritis (RA) and cardiovascular comorbidities using a Japanese health insurance database. METHOD: This population-based cross-sectional study was conducted using health insurance data provided by the Japan Medical Data Center Co., Ltd. We identified 2762 RA subjects having RA diagnostic codes (ICD10 codes; M05, M060, M062-63, M068-069) with at least two physician visits more than two months apart between June 2011 and May 2012 (RA group, n = 2762). We selected age- (±5 years), sex-, and study period-matched non-RA subjects (non-RA group, n = 27,620). We compared the prevalence of cardiovascular and related comorbidities (ischemic heart diseases [IHD], cerebral infarction, hypertension [HT], dyslipidemia [DL], and diabetes mellitus [DM]) between these groups and investigated the association between RA and cardiovascular comorbidities using a conditional logistic regression analysis. RESULTS: The prevalence of all the investigated comorbidities in the RA group was significantly higher compared to the non-RA group. Odds ratios [95% confidence interval] of RA for IHD and cerebral infarction were 2.0 [1.5-2.5] and 3.1 [2.2-4.2] respectively, after adjusting for HT, DL, and DM. CONCLUSIONS: This study revealed for the first time in the Japanese population that RA was significantly associated with cardiovascular comorbidities.

OBJECTIVE: Connective tissue disease-associated interstitial pneumonia (CTD-IP) significantly affects the mortality of patients with CTD. The purpose of the present study is to identify causes and risk factors for death during hospitalization for immunosuppressive treatment of CTD-IP. METHODS: A multicenter, retrospective study was conducted that collected data from patients with CTD who had been hospitalized for commencing or intensifying immunosuppressive treatment of CTD-IP using a standardized case report form. Risk factors were identified using the Cox proportional hazard regression model. RESULTS: A total of 322 CTD-IP patients were enrolled with rheumatoid arthritis (n = 84), systemic lupus erythematosus (n = 13), polymyositis (n = 33), dermatomyositis (n = 69), systemic sclerosis (n = 55), mixed connective tissue disease (n = 21), microscopic polyangiitis (n = 19), and overlap syndrome (n = 28). Of the 42 patients who died during hospitalization, 22 died from CTD-IP, 15 from CTD-IP and pulmonary infection, 2 from pulmonary infection, and 3 from other causes. Age ≥ 65 years and development of pulmonary infections after commencing or intensifying immunosuppressive treatments were identified as risk factors for death during hospitalization after adjusting for covariates. CONCLUSION: Careful consideration of the benefit-risk balance of immunosuppressive treatment for CTD-IP is indispensable for improving the short-term vital prognosis of these patients.

To investigate changes in the risk for serious infections (SIs) over time in Japanese rheumatoid arthritis (RA) patients treated with tumor necrosis factor inhibitors (TNFIs). This prospective cohort study included Japanese RA patients who began treatment with a TNFI from 2005 to 2007 (2005 group, n = 716, 634.2 patient years [PY]) and from 2008 to 2011 (2008 group, n = 352, 270.1 PY) at the time or after their enrollment in the registry of Japanese RA patients on biologics for long-term safety (REAL) database. Patients were observed for 12 months or until discontinuation of their initial TNFI in the REAL database. Drug discontinuation reasons and retention rates were analyzed. Incidence rates of serious adverse events (SAEs) were calculated with 95 % confidence intervals (CIs). The Cox proportional hazard model was applied to estimate the risk for SIs. The retention rate in the 2008 group was significantly lower than the 2005 group (p < 0.001). Discontinuation rates due to lack of efficacy or good control for the 2008 group were significantly higher than the 2005 group (p < 0.001). The crude incidence rate ratios comparing the 2008 group with the 2005 group for SAEs were 0.93 (95 % CI 0.65-1.34) and for SIs were 0.50 (0.24-1.03). The 2008 group had significantly lower risk for SIs than the 2005 group after adjusting for covariates (hazard ratio: 0.43 [0.20-0.93]). These results indicate significant decrease of the risk for SIs with TNFI treatment over time; this may be explained by evidence-based risk management of RA patients given TNFIs.

OBJECTIVE: To compare the incidence and risk factors of serious adverse events (SAEs) in rheumatoid arthritis (RA) patients treated with etanercept (ETN) or adalimumab (ADA) between Korean and Japanese registries. METHODS: We recruited 416 RA patients [505.2 patient-years (PYs)] who started ETN or ADA from Korean registry and 537 RA patients (762.0 PY) from Japanese registry. The patient background, incidence rate (IR) of SAE in 2 years, and risk factors for SAEs were compared. RESULTS: Korean patients were younger and used more nonbiologic DMARDs, higher doses of methotrexate, and lower doses of prednisolone (PSL). The IR of SAEs (/100 PY) was higher in the Japanese registry compared to the Korean [13.65 vs. 6.73]. In both registries, infection was the most frequently reported SAE. The only significant risk factor for SAEs in Korean registry was age by decade [1.45]. In Japanese registry, age by decade [1.54], previous use of nonbiologic DMARDs ≥ 4 [1.93], and concomitant use of oral PSL ≥ 5 mg/day [2.20] were identified as risk factors for SAEs. CONCLUSIONS: The IR of SAE in Japan, especially infection, was higher than that of Korea, which was attributed to the difference of demographic and clinical characteristics of RA patients and treatment profiles.

OBJECTIVES: To compare the risk of cardiovascular events among Janus kinase inhibitors (JAKIs), biological disease-modifying antirheumatic drugs (bDMARDs) (tumour necrosis factor inhibitors (TNFIs) and non-TNFIs) and methotrexate (MTX) in Japanese patients with rheumatoid arthritis (RA). METHODS: Using Japanese claims data, patients with RA were enrolled in this study if they had at least one ICD-10 code (M05 or M06), were new users of JAKIs, bDMARDs or MTX between July 2013 and July 2020 and being 18 years old or older. The incidence rate (IR), IR ratio and adjusted hazard ratio (aHR (95% CI)) of cardiovascular events including venous thromboembolism, arterial thrombosis, acute myocardial infarction and stroke were calculated. A time-dependent Cox regression model adjusted for patient characteristics at baseline was used to calculate aHR. RESULTS: In 53 448 cases, IRs/1000 patient-years of the overall cardiovascular events were 10.1, 6.8, 5.4, 9.1 and 11.3 under the treatments with JAKIs, bDMARDs, TNFIs, non-TNFIs and MTX, respectively. The adjusted HRs of JAKIs for overall cardiovascular events were 1.7 (1.1 to 2.5) versus TNFIs without MTX and 1.7 (1.1 to 2.7) versus TNFIs with MTX. CONCLUSIONS: Among patients with RA, individuals using JAKIs had a significantly higher risk of overall cardiovascular events than TNFIs users, which was attributed to the difference in the risk between JAKIs and TNFIs versus MTX. These data should be interpreted with caution because of the limitations associated with the claims database.
