Objective To clarify the efficacy and safety of intravenous abatacept for glandular and extraglandular involvements in Sjögren’s syndrome (SS) associated with rheumatoid arthritis (RA). Materials and methods We performed an open-label, prospective, 1-year, observational multicenter study (ROSE and ROSE II trials). The primary endpoint was the remission rate as measured by SDAI at 52 weeks. The secondary endpoints included the changes in the Saxon’s test, Schirmer’s test, ESSDAI and ESSPRI. Adverse events and adherence rates were also analyzed. Results 68 patients (36 in ROSE and 32 in ROSE II, all women) were enrolled. SDAI decreased significantly from 23.6 ± 13.2 at baseline to 9.9 ± 9.5 at 52 weeks. Patients with SDAI remission increased from 0 (0 weeks) to 19 patients (27.9%) at 52 weeks. Saliva volume increased significantly at 24 weeks. Tear volume increased significantly at 52 weeks. Both ESSDAI and ESSPRI were significantly decreased at 12 weeks, and these responses were maintained up to 52 weeks. The rate of adherence to abatacept over the 52-week period was 83.8%. Twenty-two adverse events occurred in 15 patients. Conclusion Abatacept ameliorated both glandular and extraglandular involvements, as well as the systemic disease activities and patient-reported outcomes based on composite measures, in SS associated with RA.

Objectives: To determine which grade of ultrasound (US) synovitis corresponds to clinically involved joints in rheumatoid arthritis (RA) and develops a new US-adjusted composite measure. Methods: Clinical and US examinations were performed on 137 patients with RA (28 joints). Synovial effusion, hypertrophy, and blood flow were semiquantitatively graded from 0 to 3 using gray scale (GS) and power Doppler (PD) modes. We calculated US-adjusted simple disease activity index (SDAI) and assessed feasibility, and external validity by comparing with erythrocyte sedimentation rate (ESR), and modified health assessment questionnaires (MHAQ). Results: GS ≥2 and PD ≥0 corresponds to clinically swollen joints, and GS ≥2 and PD ≥1 corresponds to tender joints. The US-adjusted SDAI showed the highest correlation when US-determined swollen joints were defined as PD ≥2 with ESR, and GS ≥3 and PD ≥2 with MHAQ. A feasible US-adjusted SDAI examining only clinically involved joints still showed a higher correlation with ESR and MHAQ than SDAI. Conclusion: Our composite measure complemented by US only for clinically involved joints is feasible and reliable for monitoring disease activity.

IntroductionWe aimed to identify causes of false-positives in ultrasound scanning of synovial/tenosynovial/bursal inflammation and provide corresponding imaging examples.MethodsWe 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 (JCR-CoSMUS).ResultsSystematic 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 pre-defined consensus (≥ 80 %) in Delphi exercise and were classified as follows: I. Gray-scale assessment (A. Non-specific synovial findings, 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, B. Reverberation). Twenty-four corresponding examples with 49 still and 23 video images also achieved consensus.ConclusionsOur study provides a set of representative images that can help sonographers to understand false-positives in ultrasound scanning of synovitis and tenosynovitis.

To clarify the clinical features of systemic lupus erythematosus (SLE) patients, factors associated with flares, and changes over time.Patients having SLE with a visiting history were entered into the Juntendo University Database of Erythematosus. We included 423 cases in the long-term follow-up analysis, and 383 cases were followed for 10 years after the initiation of any therapeutic intervention (comparative analysis: 1973-1982, 82 cases; 1983-1992, 141, and 1993-2002, 160). We assessed changes in the patients' background characteristics, disease symptoms, flare rates, etc.Among the 423 cases, the mean follow-up period was 25.9 years, and mean number of flares was 0.51. Of those, 31.9% had ≥1 flares. Thrombocytopenia at onset contributed to the flares. For disease symptoms at onset, a recent trend in increasing thrombocytopenia was observed. The combination rate of immunosuppressive agents for diseases other than lupus nephritis was slightly increased, and there was no improvement until the first flare or in the flare rate.Thrombocytopenia at onset is predictive factor for flares. Since SLE is a diverse disease with varying symptoms at recurrence, the treatment guidelines should be improved for thrombocytopenia from a long-term perspective.

A 71-year-old woman was diagnosed with rheumatoid arthritis in 2002. Treatment was started with methotrexate and she was switched to adalimumab in 2006. In May 2008, she started complaining of swelling of the left axilla and the left elbow lymph nodes, and adalimumab was discontinued in December. Her lymphadenopathy did not resolve and she was admitted to hospital with fever in May 2009. Subsequent laboratory examinations showed that serum alkaline phosphatase, gamma-glutamyl transpeptidase, C-reactive protein, and soluble interleukin-2 receptor levels were 3,078 IU/l, 510 IU/l, 20 mg/dl, and 7,290 U/ml, respectively. Gallium scintigraphy showed high-intensity areas in the above-mentioned lymph nodes. She suddenly progressed to jaundice and died of pulmonary edema on the 25th day of hospitalization. Autopsy indicated large atypical cells with a distorted nucleus that had multiplied in the above-mentioned lymph nodes. On immunohistochemical staining these cells showed positive staining for CD15, CD30, PAX-5, Epstein-Barr virus (EBV) early small RNA (EBER), and LMP-1. Reactivation of EBV was diagnosed via EBV antibodies and an EBV DNA determination. We considered that she had developed EBV-associated lymphoproliferative disorders due to immunodeficiency caused by adalimumab administration. Reactivation of EBV associated with adalimumab and the relationship of this reactivation to malignant lymphoma have been rarely reported.

The aims of this study were to analyze the clinical and pathological features of lupus nephritis (LN) and examine the association between these features and pathological condition, treatment, and prognosis. Of the 177 systemic lupus erythematosus patients who died while receiving inpatient care at Juntendo University Hospital between 1960 and 2001, we investigated the clinical features, treatment, and pathological features of 73 of these who underwent pathological autopsy and had a clear medical history. We divided these cases into two groups, i.e., those up to 1979 (Group A) and those during and after 1980 (Group B) in order to investigate changes in tendencies by age. We also divided the cases into three groups by time interval between diagnosis and death to investigate long-term prognosis. Uremia was the direct cause of death in 38.9% of cases in Group A and only 10.8% of cases in Group B. Pathological features showed a tendency to change to a sclerotic lesion as the duration of the disorder became longer. Uremia attributable to LN was the direct cause of death in relatively fewer cases, although it is still found in the majority of LN cases and remains a problem requiring stringent management. The treatment of sclerotic lesions may be an issue that needs further attention.

Treatment for rheumatoid arthritis (RA) should aim to achieve full remission. The aim of this study was to investigate predictors of persistent subclinical synovitis and whether longer clinical remission is effective in reducing subclinical synovitis.Forty-four RA patients who achieved DAS28ESR clinical remission for at least 3 months were enrolled in this study and underwent ultrasound examination of 22 joints (bilateral proximal interphalangeal joints, metacarpophalangeal joints, and wrists); bilateral hand X-ray; and blood examination. The severity of synovial effusion, synovial hypertrophy, and blood flow were semi-quantitatively graded from 0 to 3 using gray-scale (GS) and power Doppler (PD) modes.Among patients with DAS28ESR-defined clinical remission, 59.1% (26/44) demonstrated residual synovitis (≥ PD1) in at least one joint. Genant-modified total Sharp score (TSS) demonstrated the highest statistical difference between patients with and without residual subclinical synovitis (p = 0.0057), and full remission was only observed in patients with low TSS. A nonsignificant trend for decreased residual synovitis with longer sustained clinical remission was also observed (p = 0.724).Residual synovitis can persist during clinical remission, particularly in patients with progressive bone destruction. Early treatment and longer sustained clinical remission prior to bone destruction are critical for full remission.

To determine whether weighting improves the correlation of ultrasound (US) score with serum matrix metalloproteinase-3 (MMP-3) level in rheumatoid arthritis (RA).As ultrasound examination was performed on 100 RA patients, and the severity of synovial effusion and synovial hypertrophy and the blood flow were semi-quantitatively graded from 0 to 3 by using the gray-scale (GS) and power Doppler (PD) modes. We then calculated the sums of the scores of the 28 joints of each patient in the 2 modes, that is, the GS28 and PD28 scores, as well as the respective scores weighted using the Lansbury articular index (LAI, shoulder and elbow, × 12; wrist, × 8; and knee, × 24)-Lans GS28 and Lans PD28 scores.The Lans PD28 score showed a higher correlation with MMP-3 (r = 0.591; 95% confidence interval, 0.446-0.705, p0.0001) than the existing measures. The scores of the large joints-the knee, shoulder, and elbow-correlated well with the serum MMP-3 level.Weighting with the LAI can improve the correlation of US findings with serum MMP-3 level. Bidirectional approach based on both serum MMP-3 level and US scores can further improve the assessment of disease activity in RA patients.

We aim to examine changes in usage of nonbiologic, disease-modifying antirheumatic drugs (DMARDs) and evaluate their continuation rates in Japan. We analyzed DMARD treatment data for 3,734 patients with rheumatoid arthritis (RA) from 1998 to 2009 at Juntendo Hospital in Tokyo, Japan. The DMARD usage rate per month was determined to evaluate RA treatment history in the last decade. We also evaluated continuation rates of nonbiologic DMARDs in single and combination therapies and number of nonbiologic DMARD combination therapies used in each patient. We found that nonbiologic DMARD usage has dramatically changed in the last decade, with the most commonly used DMARD shifting from bucillamine to methotrexate (MTX). MTX showed the highest continuation rate; however, much lower continuation rate was observed when used alone rather than in combination treatments. Further, MTX was also used in the highest number of different combination therapies for a particular patient. These findings indicate that single MTX treatment may be unable to keep patients in clinical remission or lower disease activity compared with several combination therapies. Recent change in permitted maximum dosage of MTX from 8 to 16 mg/week may improve its efficacy and continuation rate in treating Japanese RA patients.
