RESUMO
OBJECTIVE: To assess safety of baricitinib in Japanese patients with rheumatoid arthritis in real-world clinical practice. METHODS: This all-case post-marketing surveillance study included patients initiating baricitinib for rheumatoid arthritis from September 2017 to April 2019. Treatment duration was recorded. Safety data were collected for up to 3 years from baricitinib initiation (up to 4 weeks post discontinuation in discontinuing patients). RESULTS: Safety analyses included 4720 patients; 2580 (54.7%) were ≥65 years old. Baricitinib persistence rate was 45.4% (3 year Kaplan-Meier analysis); the most common discontinuation reason was insufficient effectiveness (n = 1005, 21.3%). Serious adverse events occurred in 600 patients (incidence rate 10.42/100 patient-years; 95% confidence interval, 9.76-11.09). There were 39 deaths (incidence rate 0.43 [0.30-0.57]/100 patient-years). Incidence rate per 100 patient-years for adverse events of special interest were herpes zoster 4.68 (4.22-5.14), serious infection 3.05 (2.68-3.41), malignancy 1.09 (0.87-1.30), major adverse cardiovascular events 0.35 (0.23-0.48) and venous thromboembolism 0.25 (0.15-0.36). Incidence rates did not increase with prolonged exposure. CONCLUSIONS: No new safety concerns were identified during this 3 year post-marketing surveillance study of baricitinib in Japanese patients with rheumatoid arthritis. Patients and clinicians should be cognizant of herpes zoster and other serious infection risks during baricitinib treatment, especially in the first 6 months.
RESUMO
OBJECTIVES: To access the real-world clinical management of physicians who treat Takayasu arteritis (TAK) and giant cell arteritis (GCA) after the publication of the Japanese Circulation Society (JCS) 2017 Guidelines for the Management of Vasculitis Syndrome. METHODS: This descriptive, cross-sectional study utilized self-administered electronic questionnaires, which were answered in February 2022 by physicians treating TAK or GCA and registered with Macromill Inc. RESULTS: The 329 survey respondents comprised 110 cardiologists, 110 rheumatologists, 34 cardiovascular surgeons, 24 surgeons, 35 internal medicine physicians, 13 nephrologists, and 7 pediatricians. The 2017 JCS Guidelines were the most commonly referenced information source for resolving clinical questions, accessed by 70% of respondents. Ophthalmoscopy was performed in only 50% of patients with TAK, and in 70% for GCA. The median percentages of patients who underwent 18F-fluorodeoxyglucose-positron emission tomography/computed tomography for TAK and GCA patients were 23% and 20% at diagnosis, respectively, and 10% each at follow-up within 12 months. Tocilizumab was the most frequently used medication in combination with glucocorticoids for both TAK and GCA, especially in remission induction therapy for relapsed patients. CONCLUSIONS: The majority of physician treating TAK and GCA referred to the 2017 JCS guidelines. This report clarified the current clinical practice for large vessel vasculitis in Japan, providing information for the next revision of the guidelines.
RESUMO
BACKGROUND: Advances in rheumatoid arthritis (RA) treatment, highlighted by biological disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs), have altered the paradigm of RA treatment in the last decade. Therefore, real-world clinical evidence is needed to understand how treatment strategies and outcomes have changed. METHODS: Using an observational cohort of RA from 2012 to 2021, we collected cross-sectional data of RA patients annually to analyze a trend in RA management. For patients who initiated b/tsDMRDs, we evaluated treatment outcomes between b/tsDMARDs. Mixed-effect models were applied to examine the statistical implications of changes over time in treatment outcomes with a background adjustment. RESULTS: We analyzed annual cross-sectional data from 5070 patients and longitudinal data from 1816 patients in whom b/tsDMARDs were initiated between 2012 and 2021. b/tsDMARD use increased, whereas glucocorticoid use decreased from 2012 to 2021. Disease activity and functional disability measures improved over time. The percentage of tsDMARD prescriptions considerably increased. All b/tsDMARDs showed clinical improvements in disease activity and functional disability. Statistically, TNFi showed better short-term improvements in b/tsDMARD-naïve patients, while IL6Ri demonstrated significant long-term benefits. IL6Ri had better retention rates in switched patients. After adjustment for patient characteristics, the annual change of RA disease activity and functional disability fared significantly better from 2012 to 2021. CONCLUSIONS: With the development of new RA therapeutics, overall treatment outcomes advanced in the past decade.

OBJECTIVES: We evaluated the real-world safety/effectiveness of tofacitinib, an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA), in patients with RA in Japan registered in a post-marketing surveillance study. METHODS: This interim analysis included data from July 2013 to December 2018. Adverse events (AEs), serious AEs (SAEs), Simplified Disease Activity Index (SDAI)/Clinical Disease Activity Index (CDAI)/Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] scores, and rates of SDAI/CDAI/DAS28-4(ESR)-defined remission and low disease activity were analysed using 6 months of data. Risk factors for serious infections were assessed by multivariable analyses. RESULTS: Safety and disease activity were evaluated in 6866 and 6649 patients, respectively. Overall, 32.73%/7.37% of patients reported AEs/SAEs. Clinically important AEs with tofacitinib included serious infections/infestations [3.13% of patients; incidence rate (IR; patients with events) 6.91/100 patient-years (PY)], herpes zoster (3.63%; IR 8.02/100 PY), and malignancies (0.68%; IR 1.45/100 PY). SDAI/CDAI/DAS28-4(ESR) scores and remission/low disease activity rates improved over 6 months. Male sex, older age, Steinbrocker's stage IV, history of infection, and diabetes mellitus at baseline were independent risk factors for serious infection. CONCLUSIONS: In patients with RA receiving tofacitinib in Japan, safety was consistent with the reported profile, and disease activity improved over 6 months. STUDY IDENTIFIER: NCT01932372.

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.

Methotrexate (MTX), the anchor drug in the current treatment strategy for rheumatoid arthritis (RA), was first approved for the treatment of RA in Japan in 1999 at a recommended dose of 6-8 mg/week. The approved maximum dose of MTX has been 16 mg/week since February 2011 when MTX was approved as a first-line drug in the treatment of RA. Recent evidence of MTX-polyglutamate concentration in the red blood cells of Japanese patients with RA justifies the current daily use of MTX in Japan. Additionally, after a nationwide clinical trial, a subcutaneous MTX injection formula (7.5-15 mg/week) was approved for RA treatment in September 2022. Therefore, in March 2023, a subcommittee of the Japan College of Rheumatology updated the guidance (formerly 'guidelines') for the use of MTX in Japanese patients with RA. This article, an abridged English translation summarizing the 2023 update of the Japan College of Rheumatology guidance for the use of MTX and management of patients with RA, will be helpful to both Japanese and global rheumatology communities.

TAFRO syndrome is a rare systemic inflammatory disease. Its pathogenesis mainly involves excessive cytokine secretion and autoimmune dysfunction. Although its etiology is unclear, some viral infections have been reported to cause it. Here, we report a case of severe systemic inflammation mimicking TAFRO syndrome that arose after COVID-19. A 61-years-old woman suffered from a continuous fever, ascites, and edema after contracting COVID-19. She developed progressive thrombocytopenia, renal failure, and elevated C-reactive protein levels. She was tentatively diagnosed with multisystem inflammatory syndrome in adults (MIS-A) and received steroid pulse therapy. However, she exhibited worsening fluid retention and progressive renal failure, which are not typical of MIS-A. A bone marrow examination showed reticulin myelofibrosis and an increased number of megakaryocytes. Although a definitive diagnosis of TAFRO syndrome was not made according to current diagnostic criteria, we determined that her symptoms were clinically consistent with those of TAFRO syndrome. Combination therapy, including steroid pulse therapy, plasma exchange, rituximab, and cyclosporine, improved her symptoms. There are pathological similarities between hyperinflammation that arises after COVID-19 and TAFRO syndrome in terms of the associated cytokine storms. COVID-19 may have triggered the development of systemic inflammation mimicking TAFRO syndrome in this case.

OBJECTIVES: To assess the safety and effectiveness of baricitinib treatment for rheumatoid arthritis (RA) in real-world clinical practice. METHODS: This ongoing all-case post-marketing surveillance study (starting September 2017) includes all patients with RA treated with baricitinib in Japan. Safety and effectiveness (disease activity) were assessed for 24 weeks. RESULTS: Safety analyses to February 2021 included 4731 patients (initial baricitinib dose: 4 mg/day, n = 3058; 2 mg/day, n = 1661; other, n = 12); 1059 (22.38%) were ≥75 years and 3362 (71.06%) previously received biologic therapy. The overall observational period was 1863.14 patient-years; 1174 (24.82%) patients discontinued baricitinib before Week 24, mostly for lack of effectiveness (n = 478; 10.10%). Adverse events occurred in 1271 (26.87%) patients [serious: 203 (4.29%); death: 18 (0.38%)]. The incidence of herpes zoster, hepatic function disorder, and serious infection was 3.09%, 2.77%, and 1.90%, respectively. Malignancy occurred in 17 patients (0.36%) and major adverse cardiovascular events in seven patients (0.15%). Among patients with effectiveness data, at least 26.57% (Boolean) achieved remission at Week 24. CONCLUSIONS: This large nationwide surveillance study evaluated the safety and effectiveness of 24 weeks of baricitinib for RA in real-world clinical practice. Continued surveillance of long-term safety is ongoing.

OBJECTIVES: We conducted a descriptive study of the physicians' evidence-practice gap for adults covered by the 2017 clinical practice guidelines for the management of antineutrophil cytoplasmic antibody-associated vasculitis in Japan. METHODS: This web-based survey, conducted between January and February 2021, involved physicians who had treated at least five patients in the preceding year at a regional core hospital. The outcome was the physicians' experience in treating patients with microscopic polyangiitis or granulomatosis with polyangiitis [prevalence with 95% confidence intervals (CIs)], defined as treating at least 60% of their patients with the recommended therapy during the year. A modified Poisson regression analysis was performed to explore the factors associated with concordance. RESULTS: The 202 participants included 49 pulmonologists, 65 nephrologists, 61 rheumatologists, and other physicians. The concordance was 31.5% (95% CI, 25.1-38.5) of physicians who used cyclophosphamide or rituximab for the induction of remission. Rheumatology showed the highest concordance with published evidence (risk ratio = 2.4; 95% CI, 1.10-5.22, p = .03). CONCLUSIONS: These results suggest an evidence-practice gap, which varies substantially among subspecialties. Further studies and a new promotional initiative are necessary to close this gap in clinical practice.

OBJECTIVE: HLA-DRB1 alleles, particularly the shared epitope (SE) alleles, are strongly associated with RA. Different genetic structures underlie the production of the various autoantibodies in RA. While extensive genetic analyses have been conducted to generate a detailed profile of ACPA, a representative autoantibody in RA, the genetic architecture underlying subfractions of RF other than IgM-RF, namely IgG-RF, known to be associated with rheumatoid vasculitis, is not well understood. METHODS: We enrolled a total of 743 RA subjects whose detailed autoantibody (IgG-RF, IgM-RF, and ACPA) data were available. We evaluated co-presence and correlations of the levels of these autoantibodies. We analysed associations between the presence or levels of the autoantibodies and HLA-DRB1 alleles for the 743 RA patients and 2008 healthy controls. RESULTS: We found both IgG-RF(+) and IgG-RF(-) RA subjects showed comparable associations with SE alleles, which was not observed for the other autoantibodies. Furthermore, there was a clear difference in SE allele associations between IgG-RF(+) and (-) subsets: the association with the IgG-RF(+) subsets was solely driven by HLA-DRB1*04:05, the most frequent SE allele in the Japanese population, while not only HLA-DRB1*04:05 but also HLA-DRB1*04:01, less frequent in the Japanese population but the most frequent SE allele in Europeans, were main drivers of the association in the IgG-RF(-) subset. We confirmed that these associations were irrespective of ACPA presence. CONCLUSION: We found a unique genetic architecture for IgG-RF(-) RA, which showed a strong association with a SE allele not frequent in the Japanese population but the most frequent SE allele in Europeans. The findings could shed light on uncovered RA pathology.

This paper uses a synthetic control method (SCM) and a Ridge Augmented SCM to estimate the impact of holding the Tokyo Olympic games on the number of newly confirmed COVID-19 cases in Tokyo (Japan). Our analysis with these methods enables us to estimate the causal impact of the Tokyo Olympics on COVID-19 cases by constructing counterfactual COVID-19 cases for Tokyo (Japan) as the optimal weighted average of COVID-19 cases of OECD countries that are not affected by holding the Olympics through a data-driven approach. Based on reliable estimates obtained from different analytical settings, we find that, compared to the counterfactuals, holding the Tokyo Olympics significantly increased the daily average number of COVID-19 cases by 105 to 132 cases in Tokyo (47 to 65 cases in Japan as a whole) per million people. This result suggests that holding the Olympics likely led to the spread of COVID-19 infection in Tokyo (Japan).
RESUMO
We hypothesized that changes in skin characteristics on the forearm could be useful for early diagnosis of systemic sclerosis (SSc). We used VISIA digital imaging system to investigate this possibility for the first time. Twenty-eight Japanese patients who were diagnosed with typical or very early diagnosis of SSc (VEDOSS) were enrolled in this study, and ten age- and gender-matched patients with other disorders were included as a control group. Eight skin characteristics were analyzed. Our method of evaluating forearm skin characteristics was shown to be reproducible. The scores of WRINKLES, TEXTURE, PORES, and PORPHYRINS were higher in SSc subjects with sclerotic forearm skin (SSc forearm+; 11.004, 5.116, 3.230, and 0.084, respectively) and those without (SSc forearm-: 11.915, 4.898, 2.624, 0.0616, respectively) than in the non-SSc control subjects (10.075, 4.496, 2.459, 0.0223, respectively). Also, the scores of SPOTS, TEXTURE, PORES, UV SPOTS, BROWN SPOTS, and PORPHYRINS were elevated in SSc forearm+ (3.182, 5.116, 3.230, 5.761, 6.704, 0.084, respectively) and SSc forearm- patients (2.391, 4.898, 2.624, 9.835, 5.798, 0.0616, respectively) compared with those with VEDOSS (2.362, 4.738, 2.234, 5.999, 4.898, 0.0169, respectively). We found statistical significance in the difference in score of PORPHYRINS between SSc forearm- and VEDOSS groups (p = 0.044), and between SSc forearm+ and VEDOSS groups (p = 0.012). Therefore, they can be used to differentiate VEDOSS from early or mild SSc cases, which is sometimes clinically problematic. Our study also suggests that the porphyrin research will lead to a better understanding of SSc pathogenesis.
RESUMO
OBJECTIVE: To investigate clinical characteristics and time course of lymphoproliferative disorders (LPDs) in rheumatoid arthritis (RA) patients after methotrexate (MTX) discontinuation, in those who achieved spontaneous regression (SR). METHODS: We retrospectively reviewed clinical data from RA patients with LPDs obtained from eight institutions between 2000 and 2017 and compared clinical and pathological findings between SR and non-SR groups. RESULTS: Among 232 RA patients with LPDs, 216 were treated with MTX at the onset of LPD and 144 (66.7%) achieved SR after MTX discontinuation. Higher MTX doses, high titers of anti-CCP antibodies (>13.5 U/mL), and lower LDH and soluble IL-2 receptor levels were associated with SR. Lymphocyte count was decreased at LPD onset and increased at 2 weeks after MTX discontinuation in the SR group. Epstein-Barr virus-positive mucocutaneous ulcer, reactive lymphoid hyperplasia and unclassifiable B-cell lymphoma, were more frequent in the SR than in the non-SR group. In multivariable analysis, diffuse large B-cell lymphomas was an independent predictive factor for non-SR. In the patients with SR, 73.9% achieved partial or complete regression as early as 2 weeks after MTX discontinuation. CONCLUSION: SR and non-SR in RA patients with LPDs after MTX discontinuation were associated with certain clinical characteristics.

OBJECTIVE: To describe the clinicopathological characteristics of lymphoproliferative disorders (LPDs) in patients with rheumatoid arthritis (RA). METHODS: In this multicenter case series, we retrospectively reviewed the medical records of RA patients who were newly diagnosed as having LPDs with or without biopsy confirmation between 2000 and 2017 in eight hospitals in Japan. RESULTS: We included 232 patients with LPDs. The median age was 67 years (interquartile range [IQR], 60-73 years), and 77.1% were female. At the time of LPD diagnosis, 94.8% and 62.6% of the patients were methotrexate users and in remission or had low RA disease activity, respectively; lymphadenopathy and extranodal involvement were present in 77.1% and 51.9%, respectively. Major extranodal sites were the lungs and oral/oropharyngeal mucosa. The most common LPD pathological subtype was diffuse large B-cell lymphoma (40.5%), followed by classic Hodgkin lymphoma (10.8%), Epstein-Barr virus-positive mucocutaneous ulcer (7.7%), and reactive lymphoid hyperplasia (6.2%). The clinical and laboratory characteristics varied across the pathological subtypes. CONCLUSION: LPD occurred mainly in methotrexate users, while RA disease activity did not seem to be associated with LPD development. Although the clinical manifestations vary among pathological subtypes, manifestations of LPD in patients with RA can include lymphadenopathy, extranodal mass, and mucocutaneous ulcer.

OBJECTIVES: To clarify factors affecting 5-year survival rates and relapse rates after spontaneous regression (SR) of lymphoproliferative disorders (LPDs) in patients with rheumatoid arthritis (RA). METHODS: This retrospective longitudinal study comprised 232 patients with RA diagnosed with LPDs between January 2000 and March 2017 at eight hospitals in Japan. The Kaplan-Meier method was used to analyze survival and the Cox proportional hazard model was applied to identify predictive factors. RESULTS: Among all patients, 1-, 2- and 5-year overall survival rates were 89.5%, 86.1%, and 78.2%, respectively. Multivariable analysis revealed four 5-year survival risk factors assessed at diagnosis: age above 70 years (p = .002), deep lymphadenopathy and/or more than one extranodal lesion (p = .008), Eastern Cooperative Oncology Group/Zubrod performance status of 2-4 (p = .004), and classic Hodgkin lymphoma (CHL) histology (p = .047). Among 143 patients who achieved SR, 2- and 5-year relapse rates were 14.2% and 24.9%, respectively. CHL histology (p = .003) and serum soluble interleukin-2 receptor levels exceeding 2000 IU/L (p = .014) were associated with post-SR relapse-free survival. Blood lymphocyte counts were significantly lower at relapse than at 3-6 months prior (p < .001). CONCLUSION: Assessment of the above risk factors and routine inspection of blood lymphocyte counts could aid in the care management of LPDs in RA.

OBJECTIVES: To identify the optimal treatment for rheumatoid arthritis (RA) after the regression of lymphoproliferative disorders (LPDs). METHODS: The subjects were 232 patients with RA who developed LPD between 2000 and 2017 at seven hospitals participating in the LPD-WG study. Kaplan-Meier and Cox proportional regression analyses were performed to determine the factors associated with the rate of LPD relapse and the retention of biological disease-modifying antirheumatic drugs (bDMARDs). RESULTS: Treatment for RA was resumed in 138 patients after spontaneous regression of LPD after the discontinuation of methotrexate and in 52 patients after chemotherapy for LPD (persistent-LPD). LPD relapses occurred in 23 patients. Not DMARDs use but Hodgkin's lymphoma was identified as a risk factor for LPD relapse. In 88 RA patients treated with bDMARDs [tocilizumab, 39 patients; abatacept 20 patients; tumor necrosis factor inhibitor, 29 patients], the one-year retention rate was 67.8%. The risk factors for discontinuation of bDMARDs were persistent-LPD, non-diffuse large B-cell lymphomas (non-DLBCL), and a high clinical disease activity index (CDAI). Tocilizumab showed the highest retention rate among bDMARDs, particularly in DLBCL. CONCLUSION: Although any bDMARD could be used in patients after LPD regression, effectiveness and risk for relapse should be carefully assessed for each LPD subtype.

Background: Steroid dementia has been reported since the 1970s. In the current super-aged society, it increasingly receives attention because of the growing number of elderly people that are medicated with steroids for systemic rheumatic disease. Case Presentation: We report two cases of steroid dementia that were diagnosed as a result of careful observation of clinical symptoms and biological examination, including nuclear medicine tests. Cognitive and daily living functions were partially recovered in both cases after decrease or discontinuance of steroid medication in 2-year follow-up, but their daily living function could not be totally restored to premorbid level. Conclusion: Cognitive dysfunction caused by steroids is suggested by these cases, although definitive diagnosis in these cases is not possible. It was partially reversible over the course of a few years, but some functional loss remains. Cognitive function should be assessed appropriately before, during, and after steroid treatment. Detailed differential diagnosis of neurodegenerative disorders and longitudinal follow-up is required when cognitive dysfunction is observed after initiation of steroid therapy.
RESUMO
The prognosis of patients with connective tissue disease (CTD) has improved significantly in recent years, but interstitial lung disease (ILD) associated with connective tissue disease (CTD-ILD) remains a refractory condition, which is a leading cause of mortality. Because it is an important prognostic factor, many observational and interventional studies have been conducted to date. However, CTD is a heterogeneous group of conditions, which makes the clinical course, treatment responses, and prognosis of CTD-ILD extremely diverse. To summarize the current understanding and unsolved questions, the Japanese Respiratory Society and the Japan College of Rheumatology collaborated to publish the world's first guide focusing on CTD-ILD, based on the evidence and expert consensus of pulmonologists and rheumatologists, along with radiologists, pathologists, and dermatologists. The task force members proposed a total of 27 items, including 7 for general topics, 9 for disease-specific topics, 3 for complications, 4 for pharmacologic treatments, and 4 for non-pharmacologic therapies, with teams of 2-4 authors and reviewers for each item to prepare a consensus statement based on a systematic literature review. Subsequently, public opinions were collected from members of both societies, and a critical review was conducted by external reviewers. Finally, the task force finalized the guide upon discussion and consensus generation. This guide is expected to contribute to the standardization of CTD-ILD medical care and is also useful as a tool for promoting future research by clarifying unresolved issues.

BACKGROUND: The management of anxiety and depression symptoms in rheumatoid arthritis (RA) patients is vital. Previous study findings on this topic are conflicting, and the topic remains to be thoroughly investigated. This study aimed to clarify the association of RA disease activity with anxiety and depression symptoms after controlling for physical disability, pain, and medication. METHODS: We conducted a cross-sectional study of RA patients from the XXX Rheumatoid Arthritis Management Alliance cohort. We assessed patients using the Disease Activity Score (DAS28), Health Assessment Questionnaire Disability Index (HAQ-DI), and Hospital Anxiety and Depression Scale (HADS). Anxiety and depression symptoms were defined by a HADS score ≥ 8. We analyzed the data using multivariable logistic regression analyses. RESULTS: Of 517 participants, 17.6% had anxiety symptoms and 27.7% had depression symptoms. The multivariable logistic regression analysis demonstrated that DAS28 was not independently associated with anxiety symptoms (odds ratio [OR] [95% confidence interval; CI] 0.93 [0.48-1.78]; p = 0.82) and depression symptoms (OR [95% CI] 1.45 [0.81-2.61]; p = 0.22). However, DAS28 patient global assessment (PtGA) severity was associated with anxiety symptoms (OR [95% CI] 1.15 [1.02-1.29]; p = 0.03) and depression symptoms (OR [95% CI] 1.21 [1.09-1.35]; p < 0.01). Additionally, HAQ-DI scores ≤ 0.5 were associated with anxiety symptoms (OR [95% CI] 3.51 [1.85-6.64]; p < 0.01) and depression symptoms (OR [95% CI] 2.65 [1.56-4.50]; p < 0.01). Patients using steroids were more likely to have depression than those not using steroids (OR [95% CI] 1.66 [1.03-2.67]; p = 0.04). CONCLUSIONS: No association was found between RA disease activity and anxiety and depression symptoms in the multivariable logistic regression analysis. Patients with high PtGA scores or HAQ-DI scores ≤ 0.5 were more likely to experience anxiety and depression symptoms, irrespective of disease activity remission status. Rather than focusing solely on controlling disease activity, treatment should focus on improving or preserving physical function and the patient's overall sense of well-being.
