Headache in systemic lupus erythematosus: The LUNA registry cross-sectional study.

OBJECTIVES: This study investigated the clinically relevant factors for headaches in patients with systemic lupus erythematosus (SLE) using a registry from a Japanese multicenter cohort. METHODS: This cross-sectional study analysed the clinical information of patients with SLE who experienced headache episodes using the Migraine Disability Assessment (MIDAS) questionnaire. Significant findings in the comparisons between patients with headache (HA patients) and those without headache (non-HA patients) and in the comparisons depending on the grades of headache-induced disability in daily life based on the MIDAS scores were evaluated. Multivariate logistic regression analyses were performed to identify the relevant factors for headache. RESULTS: We analyzed 369 patients (median age, 45 years; female, 90.8%), including 113 HA patients who were significantly younger than non-HA patients (p < .005). HA patients had significantly higher frequencies of photosensitivity, rashes, and mucosal ulcers than non-HA patients (p < .05). Age and photosensitivity were significantly associated with headache (odds ratio (OR) 0.93, 95% confidence interval (CI) 0.95-0.99; OR 2.11, 95% CI 1.29-3.49, respectively). In the HA patients, hypocomplementemia was significantly associated with a disability of more than mild grade (OR 2.89, 95% CI 1.14-7.74), while rash was significantly observed in those presenting with moderate and severe disability. CONCLUSION: This study suggests that photosensitivity is a relevant manifestation of headache in patients with SLE. Persistent hypocomplementemia can contribute to headache-induced disability in daily life, whereas a rash may be a dominant manifestation in patients presenting with moderate/severe headache-induced disability.

A case of eosinophilic granulomatosis with polyangiitis associated with diffuse alveolar haemorrhage: A case report and case-based review.

A 76-year-old man with bronchial asthma was admitted for respiratory failure and bloody sputum. A significant drop in haemoglobin and multiple consolidations supported clinical diagnosis of diffuse alveolar haemorrhage (AH). Myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) was positive and urinalysis suggested glomerulonephritis. Based on eosinophilia, sinusitis, peripheral nerve involvement, and leukocytoclastic vasculitis, he was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA) associated with AH. Our case-based review suggested that male predominance (65%), high positivity for ANCA (88%) and a high frequency of renal involvement (45%) may be characteristic of AH in EGPA. Although AH is rare in EGPA, we should be aware of this life-threatening complication.

The real-world clinical decisions of physicians in the management of Takayasu arteritis and giant cell arteritis in Japan: A cross-sectional web-questionnaire survey.

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.

Effectiveness of intravenous methylprednisolone pulse in patients with severe microscopic polyangiitis and granulomatosis with polyangiitis.

OBJECTIVES: To evaluate the effectiveness and safety of two different intravenous methylprednisolone (IVMP) pulse doses in patients with severe microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). METHODS: We emulated a target trial using observational data from the nationwide registry in Japan. Patients with severe glomerulonephritis or diffuse alveolar haemorrhage were selected and pseudo-randomised into three groups using propensity score-based overlap weighting as follows: non-IVMP, IVMP 0.5 g/day, and IVMP 1.0 g/day. The primary outcome was all-cause death, and the secondary outcomes were composite all-cause death and kidney failure, severe relapse, and serious infection from 2 to 48 weeks after treatment initiation. To estimate the treatment effects, the Cox proportional hazard model and Fine-Gray subdistribution hazard model were used. RESULTS: In this emulated target trial, of 201 eligible patients (MPA, 175; GPA, 26), 6 (2.8%) died, 4 (2.0%) had kidney failure, 11 (5.3%) had severe relapse, and 40 (19.8%) had severe infections. Hazard ratios (HR) for IVMP 0.5 g/day and IVMP 1.0 g/day pulse groups compared with non-IVMP pulse were as follows: all-cause death = 0.46 (95% confidence interval [95%CI]: 0.07-2.81) and 0.07 (95%CI: 0.01-0.41); all-cause death/kidney failure = 1.18 (95%CI: 0.26-5.31) and 0.59 (95%CI: 0.08-4.52); subdistribution HRs for severe relapse = 1.26 (95%CI: 0.12-13.70) and 3.36 (95%CI: 0.49-23.29); and serious infection = 1.88 (95%CI: 0.76-4.65) and 0.94 (95%CI: 0.28-3.13). CONCLUSIONS: IVMP 1.0 g/day pulse may improve 48-week mortality in patients with severe MPA/GPA.

Evaluating the safety profile of calcineurin inhibitors: cancer risk in patients with systemic lupus erythematosus from the LUNA registry-a historical cohort study.

BACKGROUND: Previous studies have shown conflicting evidence regarding the incidence of cancer in patients with systemic lupus erythematosus (SLE) compared with that in healthy individuals. Calcineurin inhibitors (CNIs) such as cyclosporine and tacrolimus have been widely used to treat SLE; however, their effects on cancer risk remain unclear. We aimed to investigate the incidence of cancer in patients with SLE and determine the potential association between CNI use and cancer risk. METHODS: The standardized incidence ratio (SIR) of cancer among patients with lupus in the Lupus Registry of Nationwide Institutions (LUNA) was calculated based on the age-standardized incidence rate of cancer reported by Japan's Ministry of Health, Labour and Welfare. We also examined the association between CNI exposure and cancer risk, while considering potential confounding factors. The analysis accounted for confounding variables such as age, sex, smoking history, maximum glucocorticoid dose, treatment history with cyclophosphamide, ongoing hydroxychloroquine, Systemic Lupus International Collaboration Clinics/American College of Rheumatology Damage Index (SDI) value (excluding cancer occurrence), comorbidity of diabetes mellitus, and smoking history. RESULTS: The study included 704 patients with SLE (625 females; 88.8%) with a median age of 44 years [interquartile range (IQR) = 34-55] years. The median past maximum glucocorticoid dose was 40 mg/day [IQR = 30-60 mg/day], and the SDI at registration was 1 [IQR = 0-2]. Among the patients, 246 (35.1%) had smoking histories, and 38 (5.4%) experienced cancer complications. Gynecological malignancies accounted for 63.2% of all cancers. The SIR of cancer in the LUNA cohort was 1.08 (95% confidence interval [CI] = 0.74-1.43). No statistically significant risks of cancer were found in relation to CNI treatment history; the odds ratio using multiple logistic regression was 1.12 (95% CI = 0.42-3.00), the risk ratio using standardization was 1.18 (95% CI = 0.47-2.16), and the risk ratio using inverse probability weighting was 1.8 (95% CI = 0.41-4.66). CONCLUSIONS: The incidence of cancer in patients with SLE in the LUNA cohort did not significantly differ from that in the general population. These findings suggest that CNI treatment in this cohort did not pose a risk factor for cancer development.

The first presentation of a case of nail-patella syndrome newly diagnosed at the onset of rheumatoid arthritis: a case report.

BACKGROUND: Nail-patella syndrome (NPS) is a rare autosomal dominant disorder that is characterized by dysplasia of the nails, hypoplasia and/or dislocation of the patella and the presence of iliac horns. Using the CARE guidelines, we present the first reported case of NPS that was newly diagnosed at the onset of rheumatoid arthritis (RA). CASE PRESENTATION: A 74-year-old man was admitted to our hospital due to an 8-month history of arthralgia in bilateral wrists, elbows and fingers. He had a past history of glaucoma and left patella dislocation that had been operatively recentered at the age of 15 years. Laboratory data showed elevated levels of serum C-reactive protein and rheumatoid factor and an elevated titer of anti-SS-A antibodies, while estimated glomerular filtration rate (eGFR), titers of other antibodies and the results of a urinary test were normal. An X-ray showed deformity of bilateral radial heads and the right elbow, and magnetic resonance imaging (MRI) of his hands showed synovitis and erosion in the multiple swollen joints of the wrists and fingers. In addition to these typical features of RA, he had bilateral thumb nail dysplasia with mild hypoplasia of bilateral patellae and iliac horns as shown by the X-ray. He was diagnosed as having autosomal dominant disorder NPS co-existing with RA and he was treated with methotrexate in combination with an oral Janus kinase (JAK) inhibitor, leading to induction of remission. CONCLUSIONS: We have presented a rare case of NPS that was newly diagnosed at the onset of RA. Clinical and radiographic findings of NPS are highlighted in this case report for diagnosing NPS on the basis of typical manifestations.

Immunosuppressive Treatment for an anti-U1 Ribonucleoprotein Antibody-positive Patient with Pulmonary Arterial Hypertension.

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-U1 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-U1 ribonucleoprotein-antibody-positive response and might be an option for patients with these specific features.

Effect of Attending Rheumatologists' Big 5 Personality Traits on Patient Trust in Patients With Systemic Lupus Erythematosus: The TRUMP2-SLE Project.

OBJECTIVE: Differences in communication styles based on physicians' personality traits have been identified, particularly in primary care, and these physician-related factors can be important in building patient-physician trust. This study examined the effects of rheumatologists' personality traits on patients' trust in their attending rheumatologists. METHODS: This cross-sectional study included adult Japanese patients with systemic lupus erythematosus (SLE) at 5 academic medical centers between June 2020 and August 2021. The exposures were the Big 5 personality traits (ie, extraversion, agreeableness, openness, conscientiousness, and emotional stability) of attending rheumatologists using the Japanese version of the 10-Item Personality Inventory scale (1-7 points each). The outcome was the patients' trust in their attending rheumatologist using the Japanese version of the 5-item Wake Forest Physician Trust Scale (0-100 points). A general linear model was fitted. RESULTS: The study included 505 patients with a mean age of 46.8 years; 88.1% were women. Forty-three attending rheumatologists (mean age: 39.6 years; 23.3% female) were identified. After multivariable adjustment, higher extraversion and agreeableness were associated with higher trust (per 1-point increase, 3.76 points [95% CI 1.07-6.45] and 4.49 points [95% CI 1.74-7.24], respectively), and higher conscientiousness was associated with lower trust (per 1-point increase, -2.17 points [95% CI -3.31 to -1.03]). CONCLUSION: Whereas higher extraversion and agreeableness of attending rheumatologists led to higher patient trust in their rheumatologist, overly high conscientiousness may lead to lower trust resulting from the physicians' demand of responsibility and adherence to instructions from patients with SLE.

Proton Pump Inhibitors and Hyporesponsiveness to Erythropoiesis-Stimulating Agents in Hemodialysis Patients: Results from the Japan Dialysis Outcomes and Practice Patterns Study.

INTRODUCTION: Hyporesponsiveness to erythropoiesis stimulating agents (ESAs) is important problem in dialysis patients. While proton pump inhibitors (PPIs) may inhibit iron absorption, few studies have examined associations between PPIs and ESA-resistant anemia in hemodialysis patients. This study examined the associations between PPIs and ESA-resistant anemia in hemodialysis patients. METHODS: The present study was a cross-sectional study using repeated 4-month observations, up to eight observations/patient, from the Japan Dialysis Outcomes and Practice Patterns Study (J-DOPPS). The primary outcome was erythropoietin resistance index (ERI). ESA dose, hemoglobin, proportion of erythropoietin-resistant anemia, transferrin saturation (TSAT), and ferritin were also examined. Linear or risk-difference regression models were used with generalized estimating equations to account for repeated measurements. RESULTS: Of 1,644 patients, 867 patients had PPI prescriptions (52.7%). Patients prescribed PPI had higher ERI, higher ESA dose, and lower TSAT levels. Multivariable analysis for 12,048 four-month observations showed significantly greater ERI in PPI users (adjusted difference 0.95 IU/week/kg/[g/dL] [95% CI: 0.40-1.50]). Significant differences were also found in ESA dose (336 IU/week [95% CI: 70-602]) and the prevalence of erythropoietin-resistant anemia (3.9% [2.0-5.8%]) even after adjusted for TSAT and ferritin. Among possible mediators between the association of PPIs and anemia, TSAT was significantly different between PPI users and non-users (adjusted difference, -0.82% [95% CI: -1.56 to -0.07]). CONCLUSIONS: This study showed the associations between PPI and ERI, ESA dose, and TSAT in hemodialysis patients; physicians should consider anemia's associations with PPIs in hemodialysis patients.

Survey of Japanese nephrologists' use of clinical practice guidelines for rapidly progressive glomerulonephritis.

BACKGROUND: The guidelines in Japan for the treatment of rapidly progressive glomerulonephritis (RPGN) have been revised; the latest update was released in 2020. We investigated the actual usage of the new guidelines in Japan. METHODS: We distributed a survey electronically to board-certified nephrologists throughout Japan from December 15, 2021 to January 31, 2022. The survey focused on anti-neutrophil cytoplasmic antibody (ANCA)-associated RPGN and anti-glomerular basement membrane (GBM)-antibody RPGN, plus the treatment strategies and infection-prevention measures used. RESULTS: The survey was completed by 155 certified nephrologists from medical facilities across Japan. Their responses regarding treatment procedures revealed that ANCA-associated RPGN was treated with immunosuppressants and/or biologics by 58.1% of the survey respondents, and with plasma exchange (PE) in combination with corticosteroids by 21.3%. Regarding anti-GBM-antibody RPGN, 78.1% of the respondents used corticosteroids in combination with PE (63.2%), cyclophosphamide (CY) (23.9%), or rituximab (RTX) (8.4%), suggesting a discrepancy between clinical practice and the actual use of the guidelines. Trimethoprim-sulfamethoxazole was prescribed as prophylaxis by 94.8% of the respondents, reflecting the widespread recognition of the need to prevent infectious disease in patients with RPGN. CONCLUSIONS: The survey responses revealed how Japan's new RPGN guidelines are used in actual clinical practice. Our findings will contribute to the guidelines' dissemination and implementation.

Infliximab biosimilar-induced lupus nephritis: A case report.

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.

Optimal Dose of Intravenous Cyclophosphamide during remission induction therapy in ANCA-associated vasculitis: a retrospective cohort study of J-CANVAS.

OBJECTIVES: To identify the optimal dose of intravenous cyclophosphamide (IVCY) for induction therapy for anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV). METHODS: We retrospectively assessed patients with AAV who received IVCY every 2-3 weeks during the remission induction phase. The associations of the IVCY dose with infection-free survival and relapse-free survival were analysed using a Cox regression model. We compared patients in three categories: very low-dose (VLD), low-dose (LD), and conventional dose (CD) (<7.5 mg/kg, 7.5-12.5 mg/kg, and >12.5 mg/kg, respectively). The non-linear association between IVCY dose and the outcomes were also evaluated. RESULTS: Of the 80 patients (median age 72 years), 12, 42, and 26 underwent the VLD, LD, and CD regimens, respectively, of whom 4, 3, and 7 developed infection or died. The adjusted hazard ratios for infection or death were 4.3 (95% confidence interval (CI) 0.94-19.8) for VLD and 5.1 (95% CI 1.21-21.3) for CD, compared with LD. We found the hazard ratio for infection or death increased when the initial IVCY dose exceeded 9 mg/kg. Relapse-free survival did not differ clearly. CONCLUSION: Low-dose IVCY (7.5-12.5 mg/kg) may result in fewer infections and similar relapse rates compared with the conventional regimen (>12.5 mg/kg).

Protective effect of hydroxychloroquine on infections in patients with systemic lupus erythematosus: an observational study using the LUNA registry.

Objectives: Infection is a leading cause of death in patients with systemic lupus erythematosus (SLE). Alt hough hydroxychloroquine (HCQ) has been reported to inhibit infection, evidence from Asian populations remains insufficient. We investigated this effect in Japanese SLE patients. Methods: Data from the Lupus Registry of Nationwide Institutions were used in this study. The patients were ≥20 years old and met the American College of Rheumatology (ACR) classification criteria revised in 1997. We defined "severe infections" as those requiring hospitalization. We analyzed the HCQ's effect on infection suppression using a generalized estimating equation (GEE) logistic regression model as the primary endpoint and performed a survival analysis for the duration until the first severe infection. Results: Data from 925 patients were used (median age, 45 [interquartile range 35-57] years; female, 88.1%). GEE analysis revealed that severe infections were significantly associated with glucocorticoid dose (odds ratio [OR] 1.968 [95% confidence interval, 1.379-2.810], p<0.001), immunosuppressants (OR 1.561 [1.025-2.380], p=0.038), and baseline age (OR 1.043 [1.027-1.060], p<0.001). HCQ tended to suppress severe infections, although not significantly (OR 0.590 [0.329-1.058], p=0.077). Survival time analysis revealed a lower incidence of severe infections in the HCQ group than in the non-HCQ group (p<0.001). In a Cox proportional hazards model, baseline age (hazard ratio [HR] 1.029 [1.009-1.050], p=0.005) and HCQ (HR 0.322 [0.142-0.728], p=0.006) were significantly related to incidence. Conclusion: HCQ may help extend the time until the occurrence of infection complications and tends to decrease infection rates.

Impact of online health information-seeking behavior on shared decision-making in patients with systemic lupus erythematosus: The TRUMP2-SLE project.

OBJECTIVE: Providing appropriate health information to patients with systemic lupus erythematosus (SLE) is advantageous in the treatment decision-making process. We aimed to investigate how online health information-seeking behaviors affect shared decision-making (SDM) in patients with SLE. METHODS: This cross-sectional study included 464 patients with SLE from five institutions. The main exposure was time spent on the internet per day, divided into four categories (none, <1 h, 1- < 2 h, ≥2 h). Participants categorized their preferred first source of health information as physicians, the internet, or other media. The outcome was the degree of SDM measured via the 9-item Shared Decision-Making Questionnaire (SDM-Q-9). A general linear model was applied. RESULTS: Compared to no internet use, longer internet use was associated with a higher SDM-Q-9 score: <1 h, 6.9 points (95% confidence interval [CI] 0.32 to 13.6) and ≥2 h, 8.75 points, (95% CI 0.61 to 16.9). The SDM-Q-9 did not differ between the individuals who chose physicians and those who chose the Internet as their preferred first source of health information (-2.1 points, 95% CI -6.7 to 2.6). Individuals who chose other media had significantly lower SDM-Q-9 scores than those who chose physicians (-7.6 points, 95% CI -13.2 to -1.9). CONCLUSIONS: The present study suggests that SDM between physicians and patients is positively associated with online information-seeking behavior, with no negative influence associated with accessing the Internet before clinical consultations. Rheumatologists may need to introduce their patients to websites offering high-quality health information to establish a good physician-patient relationship for SDM.

Seasonal Influence on Development of Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: A Retrospective Cohort Study Conducted at Multiple Institutions in Japan (J-CANVAS).

OBJECTIVE: To clarify seasonal and other environmental effects on the onset of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: We enrolled patients with new-onset eosinophilic granulomatosis with polyangiitis (EGPA), microscopic polyangiitis (MPA), and granulomatosis with polyangiitis (GPA) registered in the database of a Japanese multicenter cohort study. We investigated the relationship between environmental factors and clinical characteristics. Seasons were divided into 4 (spring, summer, autumn, and winter), and the seasonal differences in AAV onset were analyzed using Pearson chi-square test, with an expected probability of 25% for each season. RESULTS: A total of 454 patients were enrolled, with a mean age of 70.9 years and a female proportion of 55.5%. Overall, 74, 291, and 89 patients were classified as having EGPA, MPA, and GPA, respectively. Positivity for myeloperoxidase (MPO)-ANCA and proteinase 3 (PR3)-ANCA was observed in 355 and 46 patients, respectively. Overall, the seasonality of AAV onset significantly deviated from the expected 25% for each season (P = 0.001), and its onset was less frequently observed in autumn. In ANCA serotypes, seasonality was significant in patients with MPO-ANCA (P < 0.001), but not in those with PR3-ANCA (P = 0.97). Additionally, rural residency of patients with AAV was associated with PR3-ANCA positivity and biopsy-proven pulmonary vasculitis. CONCLUSION: The onset of AAV was influenced by seasonal variations and was less frequently observed in autumn. In contrast, the occurrence of PR3-ANCA was triggered, not by season, but by rural residency.

Risk factors for cardiovascular diseases in patients with systemic lupus erythematosus: an umbrella review.

Cardiovascular disease in patients with systemic lupus erythematosus (SLE) remains one of the most common causes of death and is caused by several factors, including both traditional and disease-specific risk factors. We aimed to systematically appraise the evidence of cardiovascular disease risk factors focusing on the SLE population. The protocol for this umbrella review is registered in PROSPERO (registration no. CRD42020206858). A systematic literature search was conducted in PubMed, Embase, and the Cochrane Library from database inception to June 22, 2022, for systematic reviews and meta-analyzes that examined cardiovascular disease risk factors in patients with SLE. Two reviewers independently extracted data and assessed the quality of the included studies using the "Assessing the Methodological Quality of Systematic Reviews 2 (AMSTER 2)" tool. Of the 102 identified articles, nine systematic reviews were included in this umbrella review. All included systematic reviews were assessed as critically low quality according to the AMSTER 2 tool. The traditional risk factors identified in this study were older age, male sex, hypertension, dyslipidemia, smoking, and a family history of cardiovascular disease. SLE-specific risk factors were long-term disease duration, lupus nephritis, neurological disorders, high disease activity, organ damage, use of glucocorticoids, azathioprine, and antiphospholipid antibodies, including anticardiolipin antibodies and lupus anticoagulant. This umbrella review identified some cardiovascular disease risk factors in patients with SLE; however, the study quality of all included systematic reviews was critically low. Key Points • We examined the evidence of cardiovascular disease risk factors focusing on patients with systemic lupus erythematosus. • We found that long-term disease duration, lupus nephritis, neurological disorders, high disease activity, organ damage, use of glucocorticoids, azathioprine, and antiphospholipid antibodies, including anticardiolipin antibodies and lupus anticoagulant, were cardiovascular disease risk factors among patients with systemic lupus erythematosus. • The review indicates the need for well-validated and high-quality future reviews that assess major adverse cardiovascular events as an outcome in patients with systemic lupus erythematosus.

The Association of Grit With Burnout Components (Professional Efficacy, Exhaustion, and Cynicism) Among Academic Rheumatologists: The TRUMP 2 -SLE Study.

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.

Association between hypogammaglobulinaemia and severe infections during induction therapy in ANCA-associated vasculitis: from J-CANVAS study.

OBJECTIVES: To investigate the association between decreased serum IgG levels caused by remission-induction immunosuppressive therapy of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and the development of severe infections. METHODS: We conducted a retrospective cohort study of patients with new-onset or severe relapsing AAV enrolled in the J-CANVAS registry, which was established at 24 referral sites in Japan. The minimum serum IgG levels up to 24 weeks and the incidence of severe infection up to 48 weeks after treatment initiation were evaluated. After multiple imputations for all explanatory variables, we performed the multivariate analysis using a Fine-Gray model to assess the association between low IgG (the minimum IgG levels <500 mg/dl) and severe infections. In addition, the association was expressed as a restricted cubic spline (RCS) and analysed by treatment subgroups. RESULTS: Of 657 included patients (microscopic polyangiitis, 392; granulomatosis with polyangiitis, 139; eosinophilic granulomatosis with polyangiitis, 126), 111 (16.9%) developed severe infections. The minimum serum IgG levels were measured in 510 patients, of whom 77 (15.1%) had low IgG. After multiple imputations, the confounder-adjusted hazard ratio of low IgG for the incidence of severe infections was 1.75 (95% confidence interval: 1.03-3.00). The RCS revealed a U-shaped association between serum IgG levels and the incidence of severe infection with serum IgG 946 mg/dl as the lowest point. Subgroup analysis showed no obvious heterogeneity between treatment regimens. CONCLUSION: Regardless of treatment regimens, low IgG after remission-induction treatment was associated with the development of severe infections up to 48 weeks after treatment initiation.

Association of alcohol consumption and fatigue in SLE: A cross-sectional study from Lupus Registry of Nationwide Institution (LUNA) cohort.

OBJECTIVE: Fatigue is one of the most common complaints and is a potentially modifiable issue in systemic lupus erythematosus (SLE). Studies suggest that alcohol consumption has a protective effect against the development of SLE; however, an association between alcohol consumption and fatigue in patients with SLE has not been studied. Here, we assessed whether alcohol consumption was associated with fatigue using lupus patient-reported outcomes (LupusPRO). METHODS: This cross-sectional study, conducted between 2018 and 2019, included 534 patients (median age, 45 years; 87.3% female) from 10 institutions in Japan. The main exposure was alcohol consumption, which was defined as the frequency of drinking [<1 day/month (none group), ≤1 day/week (moderate group), and ≥2 days/week (frequent group)]. The outcome measure was the Pain Vitality domain score in LupusPRO. Multiple regression analysis was performed as the primary analysis after adjusting for confounding factors, such as age, sex, and damage. Subsequently, the same analysis was performed as a sensitivity analysis after multiple imputations (MIs) for missing data (n = 580). RESULTS: In total, 326 (61.0%) patients were categorized into the none group, 121 (22.7%) into the moderate group, and 87 (16.3%) into the frequent group. The frequent group was independently associated with less fatigue compared with none group [ß = 5.98 (95% CI 0.19-11.76), p = 0.04], and the results did not substantially deviate after MI. CONCLUSIONS: Frequent drinking was associated with less fatigue, which highlights the need for further longitudinal studies focusing on drinking habits in patients with SLE.
