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.

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.

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.

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.

OBJECTIVES: To investigate whether on-demand ultrasonography (US) assessment alongside a routine examination is useful in the management of rheumatoid arthritis (RA). METHODS: US was performed in eight (bilateral MCP 2, 3, wrist and knee) joints as the routine in a cumulative total of 406 RA patients. The most symptomatic joint other than the routine joints was additionally scanned. Power Doppler (PD) and gray-scale images were scored semiquantitatively. Eight-joint scores were calculated as the sum of individual scores for the routine joints. RESULTS: The most symptomatic joint was found among the routine joints in 209 patients (Group A) and in other joints in 148 (Group B). The PD scores of the most symptomatic joint correlated well with the 8-joint scores in Group A (rs = 0.66), but not in Group B (rs = 0.33). The sensitivity and specificity of assessment of the most symptomatic joint for routine assessment positivity were high (84.0% and 100%, respectively) in Group A, but low (50.0% and 61.8%, respectively) in Group B. Additional examination detected synovitis in 38% of Group B with negative results in the routine. CONCLUSIONS: On-demand US assessment in the most symptomatic joint, combined with the routine assessment, is useful for detecting RA synovitis.

OBJECTIVE: To compare the findings in rheumatoid arthritis (RA)-affected joints between (18)F-fluorodeoxyglucose (FDG) and (18)F-fluoride (NaF) positron emission tomography (PET)/computed tomography (CT). METHODS: We enrolled twelve RA patients who started a new biologic agent (naïve 9 and switch 3). At entry, both hands were examined by (18)F-FDG PET/CT, (18)F-NaF PET/CT, and X-ray. Intensity of PET signals was determined by standardized uptake value max (SUVmax) in metacarpophalangeal (MCP), proximal interphalangeal (PIP), and ulnar, medial, and radial regions of the wrists. Hand X-rays were evaluated according to the Genant-modified Sharp score at baseline and 6 months. RESULTS: Both (18)F-FDG and (18)F-NaF accumulated in RA-affected joints. The SUVmax of (18)F-FDG correlated with that of (18)F-NaF in individual joints (r = 0.65), though detail distribution was different between two tracers. (18)F-NaF and (18)F-FDG signals were mainly located in the bone and the surrounding soft tissues, respectively. The sum of SUVmax of (18)F-NaF correlated with disease activity score in 28 joint (DAS28), modified health assessment questionnaire (MHAQ), and radiographic progression. (18)F-FDG and (18)F-NaF signals were associated with the presence of erosions, particularly progressive ones. CONCLUSION: Our data show that both (18)F-FDG and (18)F-NaF PET signals were associated with RA-affected joints, especially those with ongoing erosive changes.

INTRODUCTION: We aimed to identify causes of false-positives in ultrasound scanning of synovial/tenosynovial/bursal inflammation and provide corresponding imaging examples. METHODS: We first performed systematic literature review to identify previously reported causes of false-positives. We next determined causes of false-positives and corresponding example images for educational material through Delphi exercises and discussion by 15 experts who were an instructor and/or a lecturer in the 2013 advanced course for musculoskeletal ultrasound organized by Japan College of Rheumatology Committee for the Standardization of Musculoskeletal Ultrasonography. RESULTS: Systematic literature review identified 11 articles relevant to sonographic false-positives of synovial/tenosynovial inflammation. Based on these studies, 21 candidate causes of false-positives were identified in the consensus meeting. Of these items, 11 achieved a predefined consensus (≥ 80%) in Delphi exercise and were classified as follows: (I) Gray-scale assessment [(A) non-specific synovial findings and (B) normal anatomical structures which can mimic synovial lesions due to either their low echogenicity or anisotropy]; (II) Doppler assessment [(A) Intra-articular normal vessels and (B) reverberation)]. Twenty-four corresponding examples with 49 still and 23 video images also achieved consensus. CONCLUSIONS: Our study provides a set of representative images that can help sonographers to understand false-positives in ultrasound scanning of synovitis and tenosynovitis.

OBJECTIVES: To investigate the optimal number and combination of joints to be assessed by power Doppler ultrasonography (PDUS) in daily practice for rheumatoid arthritis (RA). METHODS: PDUS were performed in 24 joints, including all proximal interphalangeal, metacarpophalangeal (MCP), and bilateral wrist and knee joints in 234 patients with RA. PD signals were scored semiquantitatively from 0 to 3 in each joint, and total PD score-24 was calculated by summing them up as comprehensive assessment. RESULTS: Positive PD signals were more frequently found in bilateral wrist, knee, and the second and third MCP joints than the other joints. The individual PD scores of these 8 joints also showed higher correlation coefficients with total PD score-24 (rs ≥ 0.4). Among the sum PD scores of various selected joint combinations, the score of the combination of 8 joints (total PD score-8), including bilateral second and third MCP, wrist, and knee joints, showed the highest sensitivity and negative predictive value (98.1% and 96.2%, respectively). Total PD score-8 showed high correlation with the total PD score-24 (rs = 0.97, p < 0.01). CONCLUSIONS: Total PD score-8 is simple and efficient enough for monitoring disease activity and judging imaging remission of RA in daily practice.

OBJECTIVE: To determine combined evaluation of musculoskeletal ultrasonography (MSUS) and power Doppler (PD) signals, anti-citrullinated peptide antibody (ACPA), and other clinical findings improve the prediction of joint destruction in rheumatoid arthritis (RA). METHODS: We performed a retrospective study of 331 RA patients (female n = 280 and male n = 51, mean age: 57.9 ± 13.2 years) who underwent MSUS from 2002 to 2012. Correlations with progression of joint destructions in 1,308 2nd and 3rd metacarpophalangeal (MCP) joints and various factors including PD signals of the same joints, clinical findings, age, disease duration at the study entry, gender, observation period, radiographic bone scores according to modified Sharp-van der Heijde methods, ACPA, and rheumatoid factor (RF) were analyzed in patient- and joint-based fashions, using univariate and multivariate logistic regression analyses and generalized linear mixed model. RESULTS: Patients' characteristics were as follows: mean disease duration: 5.7 ± 7.5 years, observation period: 4.6 ± 2.6 years, RF positivity: 79.9%, and ACPA positivity: 77.5%. PD-positive 2nd and 3rd joints showed higher rate of joint destruction, especially in ACPA-positive patients. Moreover, PD-positive joints in ACPA-positive patients showed joint destruction even in joints without swelling. Multivariate analysis determined PD, swollen joint (SJ), observation period, basal radiographic bone scores, and ACPA as independent risks for joint destruction. CONCLUSION: PD, SJ, basal radiographic bone scores, and ACPA are independent predictors for the joint destruction of 2nd and 3rd MCPs in RA; thus, considering these factors would be useful in daily practice.

We analyzed the clinical gastrointestinal (GI) characteristics of Behçet's disease (BD) patients in Japan. We retrospectively reviewed the clinical charts of 412 patients who fulfilled the 1987 Japanese criteria for BD and were treated in two university hospitals from July 1991 to December 2007. Forty-three patients (10.4 %) had BD-related GI lesions, which were shown by imaging examinations. Median age at BD diagnosis and onset of GI episodes were 29.6 and 31.0 years, respectively. The patients suffered from abdominal pain (30/43) and GI bleeding (18/43), while they had lower frequency of eye involvement and higher incidence of arthritis and vascular involvement than BD patients without GI lesions. The lesions were prevalent in the ileum (32/43) followed by cecum (21/43) and esophagus (9/43). The patients were treated with mesalazine and sulfasalazine (41/43), corticosteroids (32/43), immunosuppressants (13/43), and infliximab for 7 patients having refractory lesions, while 10 patients had surgical operation. Two patients died due to non-GI events during the observation. The diagnosis of BD was often difficult because of lack of eye involvement. Surgery is required for some patients in spite of intensive immunosuppressive therapies. Appropriate use of anti-TNF agents may be promising for the GI involvement.

OBJECTIVES: This pilot multicenter exercise aimed to evaluate the inter-observer reproducibility of synovial power Doppler (PD) signals in rheumatoid arthritis (RA) patients and to determine the factors influencing the measurements. METHODS: Two representative RA patients were assessed by four independent experienced sonographers. The influence of machine difference, deterioration of the transducer and pulse repetition frequency (PRF) on the assessment of synovial PD signals was investigated. RESULTS: Intra-class correlation coefficient (ICC) for the scanner-reader reproducibility of semi-quantitative PD score was high (0.867). ICC for the inter-scanner reproducibility of synovial PD pixel count was higher than that of semi-quantitative PD score. The assessment of PD signals significantly differed between two machines with quantitative measurements but did not with semi-quantitative score. The assessment of PD signals with a deteriorated transducer was much less sensitive than that with an intact one. The semi-quantitative scores for PD signals were comparable between three different PRFs (500/800/1,300 Hz), whereas the pixel count was significantly lower with the highest one in the knee joint. CONCLUSIONS: Measurement of PD signal can be substantially affected by deteriorated quality of the transducer, whereas the differences are relatively modest between machines with similar specifications and also between PRF settings within a low range.

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.

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
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.

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
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.

Immunosuppressive therapy can induce viral reactivation in patients with chronic hepatitis B virus (HBV) infection and, more rarely, in patients with resolved HBV infection. We report the case of a 57-year-old Japanese woman with rheumatoid arthritis (RA) who developed de-novo hepatitis B virus-related hepatitis after methotrexate (MTX) therapy. Entecavir and oral prednisolone following steroid pulse therapy were administered and her liver function recovered. MTX is widely used for RA for its efficiency and safety. But some cases of HBV reactivation caused by MTX, including de-novo hepatitis, have been reported. Considering these conditions, more attention should be paid when using MTX in patients with RA. And more studies are needed to determine who needs screening of HBV, monitoring of HBV-DNA, and prophylaxis with chemotherapy or immunosuppressive therapy.

Our previous survey in 2008 revealed that only 22% of Japanese rheumatologists used musculoskeletal ultrasonography (MSUS) for patient management, because of insufficient educational opportunities. To clarify the current state of MSUS usage and to identify further challenges, we conducted a second survey between October 2010 through January 2011 by sending questionnaires to 200 randomly selected Japanese rheumatologists, consisting of 100 participants in a meeting in 2009 on imaging in rheumatic diseases and 100 board-certified rheumatologists. Among the respondents, a majority (85 and 67%, respectively) used magnetic resonance imaging (MRI). MSUS users had increased from 32 to 60% of meeting participants and from 11 to 27% of other rheumatologists. The majority of MSUS users had begun using MSUS within the previous 3 years. Whereas most respondents in the previous survey had been self-taught, in the current survey many had attended training courses or had received informal training from skilled users. Despite an increase in skills and equipment ownership, obstacles to implementing MSUS remained, most prominently a lack of time. In conclusion, training courses and informal training have contributed to the popularization of MSUS in Japan. To further increase MSUS usage, additional training opportunities and education about the advantages of MSUS will be needed.

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.
