RESUMEN
OBJECTIVE: Few studies have explored whether the involvement of patients in shared decision-making (SDM) is beneficial to the management of systemic lupus erythematosus (SLE). Therefore, this study investigated the relationship between patient participation in SDM and their trust in physicians using data from the TRUMP2-SLE study. METHODS: Data regarding the nine-item Shared Decision-Making Questionnaire (SDM-Q-9 scores), Trust in Physician Scale (TIPS) scores, and Abbreviated Wake Forest Physician Trust Scale (A-WFPTS) scores for interpersonal trust in a physician and trust in the medical profession were collected from patients with SLE who visited the outpatient clinics of five facilities in Japan through a self-administered questionnaire. The relationships between these scores were analyzed by general linear models with cluster-robust variance. RESULTS: This study included 433 patients with SLE. The median baseline TIPS and A-WFPTS (attending physician version) scores were 82 (73-93) and 80 (70-95), respectively. A higher baseline SDM-Q-9 score was correlated with an increase in the TIPS score at 1 year (coefficient per 10-pt increase, 0.94 pt [95%CI 0.16-1.72]). A higher baseline SDM-Q-9 score was correlated with a higher A-WFPTS score for interpersonal trust (coefficient per 10-pt increase, 2.20 pt [1.44-2.96]). The baseline SDM-Q-9 score was also correlated with an increase in the general physician version of A-WFPTS score at 1 year (coefficient per 10-pt increase, 1.29 pt [0.41-2.18]). CONCLUSION: Engagement of patients with SLE in SDM elevates their trust in the attending physicians and healthcare providers, potentially enhancing doctor-patient relationships and overall healthcare trust.
RESUMEN
OBJECTIVES: The predictive validity of disease-specific quality of life (QOL) remains unknown in patients with systemic lupus erythematosus (SLE), although disease-specific measures are equally or more responsive to changes than generic QOL. We aimed to examine the predictive validity of the Lupus patient-reported outcome (PRO) for damage accrual. METHODS: Patients with SLE and ≥2 measurements over time were included in Japanese nationwide multicentre registry (LUNA). The Lupus PRO questionnaire contains both health-related (HR) and non-HR-QOL measures. Damage accrual was evaluated using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We examined the association between the Lupus-PRO score at baseline and longitudinal SDI scores using mixed-effects models adjusted for prognostic factors. RESULTS: Among 1295 patients, those with higher HR-QOL of Lupus PRO at baseline demonstrated a significantly lower increase in SDI (-0.005/year, 95% confidence interval [CI]: -0.007 to - 0.004, p < 0.001). According to the categorisation of HR-QOL based on tertile, a similar dose-dependent effect of HR-QOL on longitudinal SDI was identified (second vs first tertile category: -0.101/year, 95% CI: -0.172 to - 0.030; third tertile category: -0.211/year, 95% CI: -0.281 to - 0.142). Non-HR-QOL was not significantly associated with the SDI scores. Among the HR-QOL domains, cognition, procreation, and physical health were significantly associated with the total SDI scores over time. HR-QOL was associated with corticosteroid-dependent and -independent SDI scores. CONCLUSION: A higher HR-QOL of Lupus PRO was associated with a lower increase in SDI scores. Our findings imply the importance of disease-specific HR-QOL measurements in assessing prognosis.
RESUMEN
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.

The combination therapy of v-Raf murine sarcoma viral oncogene homolog B1 (BRAF) and mitogen-activated protein kinase kinase (MEK) inhibitors is approved for treating patients with BRAF V600E-positive tumours, including melanoma and lung cancer. Several case reports indicated autoimmune side effects associated with the use of BRAF and MEK inhibitors. Still, the effects of these drugs on the immune system were not fully elucidated. Here, we report a patient with large-vessel vasculitis diagnosed after initiation of treatment with dabrafenib and trametinib for BRAF V600E-positive metastatic lung adenocarcinoma. She was a never-smoker woman in her early 70s who presented with a chronic cough and was diagnosed with BRAF V600E-positive metastatic lung adenocarcinoma by transbronchial lung biopsy. She was successfully treated with prednisolone and methotrexate while BRAF and MEK inhibitors were continued. We should be careful about autoimmune diseases using BRAF and MEK inhibitors.

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.

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.

INTRODUCTION: Patients with systemic lupus erythematosus (SLE) frequently change attending physicians. The number of changes in attending physicians is related to the accumulated organ damage in patients with diabetes mellitus and inflammatory bowel disease, although similar results are not known for patients with SLE. This study investigated whether the number of attending physicians after the onset of SLE is associated with organ damage. METHODS: Patients with SLE were enrolled in a multicenter registry of 14 institutions (the Lupus Registry of Nationwide Institutions). Patients with a disease duration of 6 months to 10 years were included. Exposure was defined as the number of attending physicians. The primary outcome was the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index (SDI). The secondary outcomes were corticosteroid- and non-corticosteroid-related damage. Multiple logistic regression analysis was used to estimate the association between the number of attending physicians and SDI, adjusting for potential confounders, including age, sex, disease duration, number of hospitalizations due to SLE, disease activity at diagnosis, and emotional health. RESULTS: Of the 702 patients, 86.5% were women (median age 46 years, interquartile range 35-58). The disease duration was 7.3 years (4.3-11.3), the number of hospitalizations due to SLE was 1 (1-3), the number of attending physicians was 3 (2-4), and SDI was 0 points (0-1). The number of attending physicians was significantly associated with SDI [odds ratio (OR) 1.14, 95% confidence interval (CI) 1.03-1.26]. In the secondary outcome, the number of attending physicians was significantly associated with corticosteroid-related damage (OR 1.22, 95% CI 1.09-1.38). The number of attending physicians was not significantly associated with non-corticosteroid-related damage (OR 1.08, 95% CI 0.99-1.19). CONCLUSIONS: This study showed that SDI could increase as the number of attending physicians increases. The impact of changing attending physicians warrants greater attention for SLE and other diseases.
RESUMEN
OBJECTIVE: It is still unclear how glucocorticoids (GCs) affect the long-term clinical course of patients with SLE. The objective of this study is to explore the factors associated with GC-free treatment status. METHODS: Using data from the lupus registry of nationwide institutions, GC dose at registration was compared between short, middle and long disease durations of <5, 5-20 and ≥20 years, respectively. After excluding patients who never used GC, we evaluated the relationship between GC-free status and chronic damage using Systemic Lupus International Collaborating Clinics Damage Index. RESULTS: GC doses at enrolment of the 1019 patients were as follows: GC-free in 101 (10%); 0Asunto(s)

RESUMEN
BACKGROUND: Infection is a major cause of mortality in patients with systemic lupus erythematosus (SLE). Therefore, minimizing the risk of infection is an important clinical goal to improve the long-term prognosis of SLE patients. Treatment with ≥7.5 mg prednisolone (PSL) or equivalent has been reported to increase the risk of infections. However, it remains unclear whether <7.5 mg PSL or equivalent dose affects the risk of infection in SLE patients. This study evaluated the association between the occurrence of infection in patients with SLE and low-dose glucocorticoid (GC) usage, especially <7.5 mg PSL or equivalent, to explore the GC dose that could reduce infection occurrence. METHODS: This prospective cohort study included patients from the Japanese multicenter registry of patients with SLE (defined as ≥4 American College of Rheumatology 1997 revised criteria) over 20 years of age. The PSL dose was categorized as PSL 0-2.5, 2.6-5.0, 5.1-7.5, and 7.6-15.0 mg. The primary outcome was infection requiring hospitalization. We conducted a multivariable analysis using time-dependent Cox regression analysis to assess the hazard ratio of infection occurrence compared with a dose of 0-2.5 mg PSL or equivalent in the other three PSL dose groups. Based on previous reports and clinical importance, the covariates selected were age, sex, and concurrent use of immunosuppressants with GC. In addition, two sensitivity analyses were conducted. RESULTS: The mean age of the 509 SLE patients was 46.7 years; 89.0% were female, and 77.2% used multiple immunosuppressants concomitantly. During the observation period, 52 infections requiring hospitalization occurred. The incidence of infection with a PSL dose of 5.0-7.5 mg was significantly higher than that in the PSL 0-2.5 mg group (adjusted hazard ratio: 6.80, 95% confidence interval: 2.17-21.27). The results of the two sensitivity analyses were similar. CONCLUSIONS: Our results suggested that the use of 5.0-7.5 mg PSL or equivalent could pose an infection risk in SLE patients. This finding indicates that PSL dose should be reduced to as low as possible in SLE patients to avoid infection.

BACKGROUND: Although vitamin D concentration is reportedly associated with the pathogenesis and pathology of systemic lupus erythematosus (SLE), benefits of vitamin D supplementation in SLE patients have not been elucidated, to our knowledge. We investigated the clinical impacts of vitamin D supplementation in SLE. METHODS: A cross-sectional analysis was performed using data from a lupus registry of nationwide institutions. We evaluated vitamin D supplementation status associated with disease-related Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) as a parameter of long-term disease activity control. RESULTS: Of the enrolled 870 patients (mean age: 45 years, mean disease duration: 153 months), 426 (49%) received vitamin D supplementation. Patients with vitamin D supplementation were younger (43.2 vs 47.5 years, P < 0.0001), received higher doses of prednisolone (7.6 vs 6.8 mg/day, P = 0.002), and showed higher estimated glomerular filtration rates (79.3 vs 75.3 mL/min/1.73m2, P = 0.02) than those without supplementation. Disease-related SDI (0.73 ± 1.12 vs 0.73 ± 1.10, P = 0.75), total SDI, and SLE Disease Activity Index (SLEDAI) did not significantly differ between patients receiving and not receiving vitamin D supplementation. Even after excluding 136 patients who were highly recommended vitamin D supplementation (with age ≥ 75 years, history of bone fracture or avascular necrosis, denosumab use, and end-stage renal failure), disease-related SDI, total SDI, and SLEDAI did not significantly differ between the two groups. CONCLUSIONS: Even with a possible Vitamin D deficiency and a high risk of bone fractures in SLE patients, only half of our cohort received its supplementation. The effect of vitamin D supplementation for disease activity control was not observed.

Mixed connective tissue disease (MCTD) is a rare systemic autoimmune disease characterized by the production of anti-U1 ribonucleoprotein antibodies and systemic symptoms similar to those of some other autoimmune diseases. HLA-DRB1 polymorphisms are important genetic risk factors for MCTD, but precise associations of DRB1 genotypes with MCTD have not been reported in Japanese people. Genotyping of HLA-DRB1 and -DQB1 was performed in Japanese MCTD patients (n = 116) and controls (n = 413). Associations of specific allele carriers and genotype frequencies with MCTD were analyzed.The following alleles were found to be associated with predisposition to MCTD: HLA-DRB1*04:01 (P = 8.66 × 10-6, Pc = 0.0003, odds ratio [OR] 7.96, 95% confidence interval [CI] 3.13â20.24) and DRB1*09:01 (P = 0.0189, Pc = 0.5468, OR 1.73, 95% CI 1.12â2.67). In contrast, the carrier frequency of the DRB1*13:02 allele (P = 0.0032, Pc = 0.0929, OR 0.28, 95% CI 0.11â0.72) was lower in MCTD patients than in controls. The frequencies of heterozygosity for HLA-DRB1*04:01/*15 (P = 1.88 × 10-7, OR 81.54, 95% CI 4.74â1402.63) and DRB1*09:01/*15 (P = 0.0061, OR 2.94, 95% CI 1.38â6.25) were also higher in MCTD patients. Haplotype and logistic regression analyses suggested a predisposing role for HLA-DRB1*04:01, DQB1*03:03, and a protective role for DRB1*13:02. Increased frequencies of HLA-DRB1*04:01/*15 and DRB1*09:01/*15 heterozygous genotypes were found in Japanese MCTD patients.

OBJECTIVE: This study aimed to assess the prevalence and actual treatment conditions for hypertension and dyslipidaemia complicated with systemic lupus erythematosus (SLE). METHODS: This was a cross-sectional study. We established the lupus registry of nationwide institutions (LUNA), a multi-centre cohort of SLE patients in Japan. From February 2016 to July 2018, 597 SLE patients were registered in the LUNA. We evaluated the incidence of hypertension and dyslipidaemia and analysed the risk factors for hypertension and dyslipidaemia by logistic regression analysis. RESULTS: Overall, 597 patients were enrolled in the study. The median age was 44 years, and 88.0% of the patients were female. Among all the patients, 92.9% used prednisolone. The prevalence of hypertension and dyslipidaemia was 43.9% and 54.7%, respectively. Among the patients receiving medication for hypertension, 24.7% exhibited insufficient control (systolic blood pressure >140 mmHg or diastolic blood pressure >90 mmHg), and among those receiving medication for hyperlipidaemia, 48.1% showed insufficient control (low-density lipoprotein cholesterol >140 mg/dL or triglyceride >150 mg/dL). The risk factors for hypertension were age, body mass index (BMI), disease duration, past maximum dose of prednisolone, and renal involvement, whereas those for dyslipidaemia were age and BMI. CONCLUSION: About half of the patients had hypertension or dyslipidaemia, and a considerable number of cases were poorly controlled despite medication. Our data suggest that physicians should treat SLE activity as well as its complications, especially the common risk factors for atherosclerosis.

BACKGROUND: While survival of systemic lupus erythematosus (SLE) patients has improved substantially, problems remain in the management of their emotional health. Medium to high-dose glucocorticoid doses are known to worsen emotional health; the effect is unclear among patients receiving relatively low-dose glucocorticoids. This study aims to investigate the association between low glucocorticoid doses and emotional health in lupus low disease activity state (LLDAS). METHODS: This cross-sectional study drew on data from SLE patients in 10 Japanese institutions. The participants were adult patients with SLE duration of ≥ 1 year who met LLDAS criteria at the study visit from April 2018 through September 2019. The exposure was the daily glucocorticoid dose (mg oral prednisolone). The outcome was the emotional health score of the lupus patient-reported outcome scale (range: 0 to 100). Multiple linear regression analysis was performed with adjustment for confounders including disease-related damage, activity, and psychotropic drug use. RESULTS: Of 192 patients enrolled, 175 were included in the analysis. Their characteristics were as follows: female, 89.7%; median age, 47 years (interquartile range (IQR): 37.0, 61.0). Median glucocorticoid dose was 4.0 mg (IQR 2.0, 5.0), and median emotional health score 79.2 (IQR 58.3, 91.7). Multiple linear regression analysis showed daily glucocorticoid doses to be associated with worse emotional health (ß coefficient = - 2.54 [95% confidence interval - 4.48 to - 0.60], P = 0.01). CONCLUSIONS: Daily glucocorticoid doses were inversely associated with emotional health among SLE patients in LLDAS. Further studies are needed to determine whether glucocorticoid tapering leads to clinically significant improvements in emotional health.

BACKGROUND: We hypothesized that Behçet's disease (BD) consists of several clinical subtypes with different severity, resulting in heterogeneity of the disease. Here, we conducted a study to identify clinical clusters of BD. METHODS: A total of 657 patients registered in the Yokohama City University (YCU) regional BD registry between 1990 and 2018, as well as 6754 patients who were initially registered in the Japanese Ministry of Health, Labour and Welfare (MHLW) database between 2003 and 2014, were investigated. The YCU registry data regarding the clinical manifestations of BD, human leukocyte antigen (HLA) status, treatments, and hospitalizations were analyzed first, followed by similar analyses of the MHLW for validation. A hierarchical cluster analysis was independently performed in both patient groups. RESULTS: A hierarchical cluster analysis determined five independent clinical clusters in the YCU cohort. Individual counterparts of the YCU clusters were confirmed in the MHLW registry. Recent phenotypical evolutions of BD in Japan, such as increased gastrointestinal (GI) involvement, reduced complete type according to the Japan Criteria, and reduced HLA-B51 positivity were associated with chronologically changing proportions of the clinical clusters. CONCLUSIONS: In this study, we identified independent clinical clusters among BD patients in Japan and found that the proportion of each cluster varied over time. We propose five independent clusters namely "mucocutaneous", "mucocutaneous with arthritis", "neuro", "GI", and "eye."

AIMS: We compared the incidence of adverse events between single and divided-dose regimens of methotrexate (MTX) by using a multicenter randomized controlled trial. METHODS: Eighty-nine patients with insufficient control on MTX 8 mg/wk were randomly assigned into single-dose (39 patients) or triple dose (39 patients) groups. The MTX dose for all patients was gradually increased to 16 mg/wk. The primary endpoint was the occurrence of liver dysfunction during the observation period (20 weeks). RESULTS: There were no differences in baseline data and MTX dose at Week 20 between groups. There was no significant difference in the incidence of liver dysfunction between groups (single dose, 3 [7.7%] patients vs. triple dose, 5 [13.2%] patients; P = .455). The incidence of adverse event increased in triple dose (single dose, 12 [30.8%] patients vs. triple dose, 20 [51.3%]), but the difference was not significant (P = .066). There was no significant difference in disease activity between groups, although MTX-triglutamate (PG3), MTX-PG4, and MTX-PG5 were significantly higher in the single dose group. CONCLUSIONS: Weekly split dosing reduced the polyglutamation of MTX. There was no significant difference in efficacy and safety between the 2 groups.

Objectives: Although intensive immunosuppressive treatment is necessary for the severe cases with polymyositis (PM)/dermatomyositis (DM), the prognostic factors or disease activity indices for PM/DM have not been established. Here we investigated the association between serum microRNA-1 (miR-1) level and clinical course of patients with PM/DM.Methods: We retrospectively reviewed baseline clinical and laboratory findings, treatment regimens and outcomes in patients with PM/DM. The serum samples were collected from PM/DM patients and healthy controls (HC). Serum miR-1 levels were determined by quantitative real-time PCR.Results: Twenty-two patients were recruited. The average serum miR-1 level was significantly higher in the PM/DM as compared to HC (p = .0085) and was decreased by treatment (p = .032). We divided the PM/DM-ILD patients into two groups, high and normal miR-1 groups. Although there were no significant differences in the clinical data and the initial prednisolone (PSL) dose between the two groups, PSL dose at 16 weeks, cumulative PSL dose until 16 weeks, and frequency of serious infections were significantly higher in the high miR-1 group as compared to the normal group (p = .025, .036, and .026, respectively).Conclusion: We propose serum miR-1 as a promising novel biomarker for predicting therapeutic response in PM/DM-ILD.

Genome-wide association studies of systemic lupus erythematosus (SLE) in Chinese and Korean populations demonstrated strong association of single nucleotide polymorphisms (SNPs) located in the GTF2I-NCF1 region, rs73366469 (GTF2I), rs117026326 (GTF2I), rs80346167(GTF2IRD1) and rs201802880 (NCF1). This region has also been associated with susceptibility to Sjögren syndrome and rheumatoid arthritis; however, association studies with systemic sclerosis (SSc) and ANCA-associated vasculitis (AAV) have not been reported. Here we made an attempt to confirm their associations with SLE in the Japanese population, to find the primarily associated SNP, and to investigate whether these SNPs are also associated with susceptibility to SSc and AAV. By genotyping these four SNPs on 842 SLE, 467 SSc, 477 AAV patients and 934 healthy controls, striking association was confirmed in Japanese SLE. In addition, these SNPs were significantly associated with susceptibility to SSc, but not with AAV. Conditional logistic regression analysis revealed that the association of NCF1 rs201802880, a missense SNP encoding p.Arg90His, can account for the association of other SNPs by linkage disequilibrium. These results suggested that GTF2I-NCF1 region is associated with susceptibility to multiple autoimmune rheumatic diseases but not with AAV, and the primarily associated variant may be the missense SNP in NCF1.

AIM: To determine characteristics of rheumatoid arthritis (RA) patients in Japan who received the same biological disease-modifying antirheumatic drugs (bDMARDs) for at least 6 months and to identify factors associated with successful down-titration of bDMARDs dependent on shared decision-making. METHODS: We included consecutive RA patients who received the same bDMARD with low disease activity or remission for at least 6 months in our two university hospitals. Patients treated with the bDMARD standard dose were defined as SD, while those treated with bDMARD down-titration were defined as DT. We retrospectively reviewed clinical charts and compared data between the two groups. RESULTS: Of 288 patients with RA, 204 (70.8%) and 84 (29.2%) continued standard dose treatment and underwent down-titration treatment, respectively. Sixty-six of 84 (78.6%) down-titration-treated patients continued to show low disease activity or remission, whereas 18 (21.4%) relapsed 18.9 ± 24.4 months after bDMARD down-titration was started. Univariate predictor analysis showed that the probable factors of down-titration were no history of bDMARD treatment (P = .001) and low initial Disease Activity Assessment of 28 joint score (P = .048). Other clinical characteristics had no significant relationship with successful down-titration. CONCLUSIONS: Thus, bDMARD-naïve patients and those with low initial disease activity are more likely to agree to attempt down-titration. However, the timing and method of down-titration should be made in shared decision-making between patients and rheumatologists.

BACKGROUND: Interstitial lung disease (ILD) is the principal cause of death in polymyositis/dermatomyositis (PM/DM). Here we investigated prognostic factors for death and serious infection in PM/DM-ILD using the multicenter database. METHODS: We retrospectively reviewed baseline demographic, clinical and laboratory findings, treatment regimens and outcomes in patients with PM/DM-ILD. The distribution of ILD lesions was evaluated in four divided lung zones of high-resolution computed tomography images. RESULTS: Of 116 patients with PM/DM-ILD, 14 died within 6 months from the diagnosis. As independent risk factors for early death, extended ILD lesions in upper lung fields (odds ratio (OR) 8.01, p = 0.016) and hypocapnia (OR 6.85, p = 0.038) were identified. Serious infection was found in 38 patients, including 11 patients who died of respiratory or multiple infections. The independent risk factors were high serum KL-6 (OR 3.68, p = 0.027), high initial dose of prednisolone (PSL) (OR 4.18, p = 0.013), and combination immunosuppressive therapies (OR 5.51, p < 0.001). CONCLUSION: The present study shows the progression of ILD at baseline is the most critical for survival and that infection, especially respiratory infection, is an additive prognostic factor under the potent immunosuppressive treatment.

Objective: To evaluate diagnostic test accuracy of US compared with MRI for the detection of synovitis in RA patients. Methods: A systematic literature search was performed in the PubMed, EMBASE, Cochrane Library and Web of Science Core Collection databases. Studies evaluating the diagnostic test accuracy of US for synovitis detected by MRI as the reference standard for wrist, MCP, PIP and knee joints were included. To assess the overall accuracy, we calculated the diagnostic odds ratio using a DerSimonian-Laird random effects model and the area under the curve (AUC) for the hierarchical summary receiver operating characteristics using Holling's proportional hazards models. The summary estimate of the sensitivity and specificity were obtained using the bivariate model. Results: Fourteen of 601 identified articles were included in the review. The diagnostic odds ratio was 11.6 (95% CI 5.6, 24; I2 = 0%), 28 (95% CI 12, 66; I2 = 11%), 23 (95% CI 6.5, 84; I2 = 19%) and 5.3 (95% CI 0.60, 48; I2 = 0%) and the AUC was 0.81, 0.91, 0.91 and 0.61 for wrist, MCP, PIP and knee joints, respectively. The summary estimates of sensitivity and specificity were 0.73 (95% CI 0.51, 0.87)/0.78 (95% CI 0.46, 0.94), 0.64 (95% CI 0.43, 0.81)/0.93 (95% CI 0.88, 0.97), 0.71 (95% CI 0.33, 0.93)/0.94 (95% CI 0.89, 0.97) and 0.91 (95% CI 0.56, 0.99)/0.60 (95% CI 0.20, 0.90) for wrist, MCP, PIP and knee joints, respectively. Conclusion: US is a valid and reproducible technique for detecting synovitis in the wrist and finger joints. It may be considered for routine use as part of the standard diagnostic tools in RA.
