Objectives Although personality characteristics of patients with SLE affect their disease activity and damage, it is unclear whether those of attending physicians affect the outcomes of patients with SLE. Grit is a personality trait for achieving long-term goals that may influence the decision-making for continuing treatment plans for patients. We aimed to evaluate the relationship between the grit of attending physicians and achievement of treatment goals in patients with SLE. Methods This cross-sectional study was conducted at five referral hospitals. The main exposure was 'consistency of interest' and 'perseverance of effort' of the attending physicians, measured by the Short Grit Scale. The primary outcome was achievement of a lupus low disease activity state (LLDAS). The association between physicians' grit score and LLDAS was analysed by generalized estimating equation (GEE) logistic regression with cluster robust variance estimation, with adjustment for confounders. Results The median (interquartile range) total, consistency and perseverance scores of 37 physicians were 3.1 (2.9–3.6), 3.3 (2.8–3.8) and 3.3 (3.0–3.5), respectively. Among the 386 patients, 154 (40%) had achieved LLDAS. Low consistency score (≤2.75) in physicians was related to LLDAS achievement independently using GEE logistic regression. The score of the question 'I often set a goal but later choose to pursue a different one' was significantly higher in patients achieving LLDAS. Conclusions Difficulty of attending physicians to change treatment goals might be related to lower LLDAS achievement in patients with SLE. [ABSTRACT FROM AUTHOR]

A 34-year-old woman with pulmonary arterial hypertension (PAH) was admitted to the hospital. She had been diagnosed with PAH three years earlier and treated with triple vasodilator therapy. She was positive for anti-U 1 ribonucleoprotein antibodies but did not show any other symptoms associated with autoimmune diseases. Corticosteroid and cyclophosphamide therapy was administered, suspecting the involvement of immunological pathophysiology. After 3 weeks, the mean pulmonary artery pressure decreased from 50 to 38 mmHg without any change in the vasodilators. Immunosuppressive therapy was effective in this patient with PAH with an anti-U 1 ribonucleoprotein-antibody-positive response and might be an option for patients with these specific features.

We present a case of microhematuria, proteinuria and hypocomplementemia which developed in a 55-year-old female who was being treated with an infliximab biosimilar for rheumatoid arthritis. Renal biopsy showed lupus nephritis (ISN/RPS classification class IV + V). Treatment with the infliximab biosimilar was discontinued, and treatment with prednisolone, hydroxychloroquine and abatacept was started, resulting in clinical remission of lupus nephritis and RA. Although tumour necrosis factor-α α inhibitors are known to induce production of autoantibodies, symptoms are usually limited to skin involvement or arthritis, and renal complications are rare. Physicians should be aware of the risk of lupus nephritis and carefully monitor patients for the development of renal involvement during treatment with tumour necrosis factor-α inhibitors., (© Japan College of Rheumatology 2023.

Objectives: There is a high prevalence of burnout among rheumatologists. Grit, which is defined as possessing perseverance and a passion to achieve long-term goals, is predictive of success in many professions; however, whether grit is associated with burnout remains unclear, especially among academic rheumatologists, who have multiple simultaneous responsibilities. Thus, the purpose of this study was to examine the associations between grit and self-reported burnout components-professional efficacy, exhaustion, and cynicism-in academic rheumatologists., Methods: This cross-sectional study involved 51 rheumatologists from 5 university hospitals. The exposure was grit, measured using mean scores for the 8-item Short Grit Scale (range, 1-5 [5 = extremely high grit]). The outcome measures were mean scores for 3 burnout domains (exhaustion, professional efficacy, and cynicism; range, 1-6; measured using the 16-item Maslach Burnout Inventory-General Survey). General linear models were fitted with covariates (age, sex, job title [assistant professor or higher vs lower], marital status, and having children)., Results: Overall, 51 physicians (median age, 45 years; interquartile range, 36-57; 76% men) were included. Burnout positivity was found in 68.6% of participants (n = 35/51; 95% confidence interval [CI], 54.1, 80.9). Higher grit was associated with higher professional efficacy (per 1-point increase; 0.51 point; 95% CI, 0.18, 0.84) but not with exhaustion or cynicism. Being male and having children were associated with lower exhaustion (-0.69; 95% CI, -1.28, -0.10; p = 0.02; and -0.85; 95% CI, -1.46, -0.24; p = 0.006). Lower job title (fellow or part-time lecturer) was associated with higher cynicism (0.90; 95% CI, 0.04, 1.75; p = 0.04)., Conclusions: Grit is associated with higher professional efficacy among academic rheumatologists. To prevent burnout among staff, supervisors who manage academic rheumatologists should assess their staff's individual grit., Competing Interests: N.K. is a member of the Committee on Clinical Research, Japan College of Rheumatology, and has received grants from the Japan Society for the Promotion of Science, consulting fees from GlaxoSmithKline K.K., and payments for speaking at and participating in educational events from Chugai Pharmaceutical Co, Ltd, Sanofi K.K., Mitsubishi Tanabe Pharma Corporation, and the Japan College of Rheumatology.

Objectives: To determine prognostic factors of methotrexate-associated lymphoproliferative disorder (MTX-LPD) and evaluate the efficacy and safety of biological therapy in rheumatoid arthritis (RA) complicated with MTX-LPD., Methods: Thirty RA patients who developed MTX-LPD were investigated in this study. We compared the clinical and laboratory parameters of patients who achieved regression of LPD by MTX withdrawal with those who required chemotherapy and evaluated the clinical course of RA after LPD development., Results: Twenty-three patients (76.7%) achieved regression of LPD by MTX withdrawal. Chemotherapy-free patients had a tendency of shorter RA duration (13.1 vs. 22.0 years, p = 0.108) and higher doses of MTX at LPD diagnosis (8.0 vs. 5.3 mg/w, p = 0.067) than patients who required chemotherapy. A significantly higher positive rate of peripheral blood Epstein-Barr virus (EBV)-DNA was observed in the chemotherapy-free group (9/9 vs. 0/3, p = 0.0002). Of 15 patients that received biological agents after LPD development, 14 patients (93.3%) demonstrated an improved disease activity of RA and persistent remission of LPD, whereas only one patient experienced relapse of LPD during tocilizumab therapy., Conclusions: Peripheral blood EBV-DNA positivity is a potential prognostic marker of better outcome in MTX-LPD. Biological agents could be an option for the treatment of RA patients with MTX-LPD.
