Abstract
AIM This study aimed to analyze the muscle magnetic resonance imaging (MRI) findings of patients with antineutrophilic cytoplasmic antibody-associated vasculitis (AAV) and polyarteritis nodosa (PAN) presenting with clinical symptoms in the extremities. METHODS Retrospective analysis was conducted on short tau inversion recovery MRI findings, with a focus on intramuscular vessels displaying abnormal perivascular signals, in 22 and eight patients with AAV and PAN, respectively. The number per unit area (4 cm2) and diameter of abnormal vessels on muscle MRI were compared between patients with AAV and those with PAN. Cut-off values, clinical sensitivity, and specificity for these indices were calculated from the receiver operating characteristic curves to distinguish between AAV and PAN, and the relationship between the indices and clinical findings in AAV was analyzed. RESULTS The number of abnormal vessels per unit area was significantly higher in AAV compared to PAN (p < .05). Additionally, the diameter of the abnormal vessels was significantly higher in PAN than in AAV (p < .05). The presence of >6.44 abnormal vessels per unit area or ≤3.61 mm diameter of abnormal vessels was able to predict AAV (sensitivity, 0.955; specificity, 0.625). AAV patients with peripheral neuropathy exhibited a significantly higher number of abnormal vessels per unit area than those without peripheral neuropathy (p < .05). CONCLUSIONS Muscle MRI can detect small- to medium-vessel vasculitis and be a valuable tool for distinguishing between patients with AAV and PAN experiencing clinical symptoms in the extremities.

Abstract
OBJECTIVE Idiopathic inflammatory myopathies (IIMs) are autoimmune disorders significantly impacting skeletal muscles; however, the precise correlation between muscle magnetic resonance imaging (MRI) findings, muscle pathology, disease subtypes, and clinical characteristics remains uncertain. Thus, we investigated the association of muscle MRI findings in IIMs with muscle pathology and clinical features. METHODS New-onset IIM patients underwent proximal upper and/or lower limb muscle MRI. Patterns of muscle oedema on MRI were categorised into fascial, honeycomb, peripheral, foggy, dense, or coarse dot patterns and compared with inflammatory cell infiltration sites in corresponding muscle biopsies. The incidence of MRI patterns was examined in patient subgroups using myositis-specific antibodies (MSAs) and 2017 EULAR/ACR classification criteria. Univariate and multivariate analyses were conducted to determine the odds ratios (ORs) of MRI findings for clinical characteristics. RESULTS Fifty-six of 85 patients underwent muscle biopsy. Foggy, honeycomb, and fascial patterns at biopsy sites correlated with inflammatory cell infiltration in the endomysium (OR 11.9, p= 0.005), perimysium (OR 6.0, p= 0.014), and fascia (OR 16.9, p< 0.001), respectively. Honeycomb and foggy patterns were characteristic of patients with anti-TIF1γ or anti-Mi2 antibodies and MSA-negative dermatomyositis, and those with anti-SRP or anti-HMGCR antibodies and MSA-negative polymyositis (PM), respectively. The honeycomb pattern positively correlated with malignancy (OR 6.87, p< 0.001) and Gottron sign (OR 8.05, p= 0.002); the foggy pattern correlated with muscle weakness (OR 11.24, p= 0.005). The dense dot pattern was associated with dysphagia (OR 6.27, p= 0.006) and malignancy (OR 8.49, p= 0.002). CONCLUSION Muscle MRI holds promise in predicting muscle pathology, disease subtypes, and clinical manifestations of IIMs.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease that causes damage to multiple organs. Various factors, including vaccination, have been associated with SLE development. Vaccination for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in 2020, and there are a few reports on the exacerbation of SLE after SARS-CoV-2 vaccination. The influence of SARS-CoV-2 vaccination on SLE development remains unclear. We present the case of a 53-year-old man who developed peritonitis and was subsequently diagnosed with SLE on Day 9 after receiving a third dose of the messenger ribonucleic acid-1273 SARS-CoV-2 vaccine. This case and previous reports have shown that patients who developed SLE after SARS-CoV-2 vaccination are more likely to develop it within 2 weeks of vaccination, especially when they have a higher rate of immunological abnormalities or a family history of autoimmune diseases. Furthermore, these features suggest that type I interferon is involved in the pathogenesis of SLE after SARS-CoV-2 vaccination.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) can be comorbid with psychiatric symptoms. Brain abnormalities in RA patients and in arthritis models have been reported. However, it remains unclear when these abnormalities occur and where they are distributed. In this study, we analyzed spatiotemporal changes in gene expression in the brains of mice with collagen-induced arthritis (CIA). METHODS Mice were divided into three groups: (i) CIA (all mice developed arthritis on day 35): complete Freund's adjuvant (CFA) and type II collagen at initial immunization, and incomplete Freund's adjuvant (IFA) and type II collagen at booster immunization; (ii) C(+/-) (50% mice developed arthritis on day 35): only IFA at booster immunization; and (iii) C(-/-) (no arthritis): only CFA at initial immunization and only IFA at booster immunization. Whole brains were collected at ten stages of arthritis and divided into six sections. Real-time polymerase chain reaction was performed using RNA extracted from the brain, and the expression of proinflammatory cytokines and glial markers was semi-quantified. Arthritis score, body weight, and food and water intakes were recorded and analyzed for correlations with brain gene expression. We also investigated the effect of interleukin-6 (IL-6) injection in the olfactory bulbs (OBs) on the food intake. RESULTS After booster immunization, a transient increase in Integrin subunit α-M and IL-1β was observed in multiple areas in CIA. IL-6 is persistently expressed in the OB before the onset of arthritis, which is correlated with body weight loss and decreased food intake. This change in the OB was observed in the C(+/-) but not in the C(-/-) groups. In the C(+/-) group, non-arthritic mice showed the same changes in the OB as the arthritic mice. This elevation in IL-6 levels persisted throughout the chronic phase until day 84. In addition, IL-6 injection into the OB reduced food intake. CONCLUSION Persistent elevation of IL-6 in the OB from the early stage of arthritis may be an important finding that might explain the neuropsychiatric pathophysiology of RA, including appetite loss, which is present in the early stages of the disease and manifests as a variety of symptoms over time.

Abstract
OBJECTIVES Anti-differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis, which has been described as clinically amyopathic dermatomyositis, complicates rapidly progressive interstitial lung disease (ILD). Owing to the absence of significant muscle symptoms, musculoskeletal MRI is often not performed. In this study, we aimed to devise a simple evaluation method using musculoskeletal MRI findings to elucidate the relationship between MRI findings and ILD prognosis and development. METHODS The medical records and MRI scans of the proximal muscles at the time of diagnosis were retrospectively reviewed for 28 patients with anti-MDA5 antibody-positive dermatomyositis who were admitted to The Jikei University Hospital and The Jikei University Kashiwa Hospital between January 2008 and March 2022. Three observers evaluated nine proximal muscles for high signals on either short-tau inversion recovery images and/or fat-saturated gadolinium-enhanced T1-weighted images in the fascia and/or in the margins of the muscles in contact with the fascia (fascial pattern), and/or high signals in the muscles away from the fascia (intramuscular pattern), and a consensus was reached. RESULTS Of the 28 patients, 15 presented with 'radiological myositis', where an intramuscular pattern was observed at any site. Patients with radiological myositis had significantly higher survival rates than those without radiological myositis, despite the lower rate of triple therapy with prednisolone, calcineurin inhibitors and cyclophosphamide. The spread of ILD on chest CT negatively and significantly correlated with the proportion of intramuscular lesions. CONCLUSION The detection of intramuscular lesions on musculoskeletal MRI using our novel evaluation method could be clinically useful as a favourable prognostic marker.

Abstract
Peptidylarginine deiminase 4 (PAD4) contributes to the production of citrullinated proteins as autoantigens for anti-citrullinated protein antibodies (ACPAs) in rheumatoid arthritis (RA). PAD4 can also self-deiminate via autocitrullination. However, the role of this process in RA pathogenesis has not been elucidated. This study aimed to clarify PAD4 function before and after autocitrullination and identify citrullinated PAD4 in the synovial fluid of patients with RA. The autocitrullination of recombinant human PAD4 (rhPAD4) was catalyzed in vitro and determined using anti-modified citrulline immunoblotting. Monocyte chemotaxis was evaluated using Boyden chambers, and citrullinated rhPAD4's ability to induce arthritis was assessed in a C57BL/6J mouse model. Citrullinated PAD4 levels were measured in the synovial fluid of patients with RA and osteoarthritis using a novel enzyme-linked immunosorbent assay. Chemotactic findings showed that citrullinated rhPAD4 recruited monocytes in vitro, whereas unmodified rhPAD4 did not. Compared to unmodified rhPAD4, citrullinated rhPAD4 induced greater inflammation in mouse joints through monocyte migration. More citrullinated PAD4 was found in the synovial fluid of patients with RA than in those with osteoarthritis. Citrullinated PAD4 was even detected in ACPA-negative patients with RA. The autocitrullination of PAD4 amplified inflammatory arthritis through monocyte recruitment, suggesting an ACPA-independent role of PAD4 in RA pathogenesis.

Abstract
OBJECTIVE Idiopathic inflammatory myopathies (IIM) demonstrate characteristic clinical phenotypes depending on the myositis-specific antibody (MSAs) present. We aimed to identify common or MSA-specific immunological pathways in different immune cell types from peripheral blood by transcriptome analysis. METHODS We recruited 33 patients with IIM who were separated into the following groups: 15 patients with active disease at onset and 18 with inactive disease under treatment. All patients were positive for MSAs: anti-melanoma differentiation-associated gene 5 (MDA5) antibody (Ab) in 10 patients, anti-Mi-2 Ab in 7, and anti-aminoacyl-transfer RNA synthetase (ARS) Ab in 16. The patients were compared with 33 healthy controls. Twenty-four immune cell types sorted from peripheral blood were analyzed by flow cytometry, RNA sequencing, and differentially expressed gene analysis combined with pathway analysis. RESULTS The frequencies of memory B cell types were significantly decreased in active patients, and the frequency of plasmablasts was prominently increased in active patients with anti-MDA5 Ab in comparison with healthy controls. The expression of type I interferon (IFN)-stimulated genes of all immune cell types was increased in the active, but not inactive, patients. Endoplasmic reticulum stress-related genes in all IIM memory B cells and oxidative phosphorylation-related genes in inactive IIM double negative B cells were also increased, suggesting prominent B cell activation in IIM. Furthermore, active patients with anti-MDA5 Ab, anti-Mi-2 Ab, or anti-ARS Ab were distinguished by IFN-stimulated and oxidative phosphorylation-related gene expression in plasmablasts. CONCLUSION Unique gene expression patterns in patients with IIM with different disease activity levels and MSA types suggest different pathophysiologies. Especially, B cells may contribute to common and MSA-specific immunological pathways in IIM.

Abstract
OBJECTIVES In patients with rheumatoid arthritis (RA), baricitinib not only improves arthritis symptom severity, but also patients' neuropsychological symptoms, such as depression and fatigue. However, the cellular mechanisms through which baricitinib can affect neural activity is unexplored. While the blood-brain barrier (BBB) permeability of this drug remains unclear, Janus kinase inhibitors (JAKi) might reach the area postrema (AP), which is a unique brain region with a weak BBB function. Our recent study demonstrated microglial activation during experimental arthritis in the AP. Therefore, we sought to assess the effect of baricitinib on microglia in the AP using collagen-induced arthritis mouse model. METHODS Microglia number and morphology in the AP were assessed by immunostaining for ionized calcium-binding adaptor molecule-1 (Iba-1). Data were collected on post-immunization day 35 (early phase) and 84 (late phase), and compared between baricitinib- and vehicle-treated mice. The effect on signal transducers and activators of transcription (STAT3) in the AP was also immunohistochemically examined. Behavioral outcomes were assessed by examining feeding behaviors and sucrose preference tests. RESULTS In the early phase, activated microglial levels in the AP were decreased by baricitinib, accompanied by the inhibition of phosphorylated-STAT3 and recovery of food intake and sucrose preference. On the other hand, baricitinib did not affect microglial morphology in the late phase. CONCLUSION Our results demonstrate that baricitinib can affect brain cells, specifically microglia, in the brain region with a weak BBB and mitigate aberrant behaviors during autoimmune arthritis, pointing to the potential therapeutic effect of JAKi on brain pathologies underpinning RA.

Abstract
OBJECTIVES Central sensitivity syndrome (CSS) comprises various symptoms caused by central sensitisation (CS). Using the central sensitisation inventory (CSI), a screening questionnaire developed for detecting CSS, this syndrome was recently identified in patients with long-standing rheumatoid arthritis (RA). However, the descriptors of CS-related pain and the effects of CSS on symptoms in patients with rheumatoid arthritis (RA) remain unknown. We examined the characteristics of pain and influence of CSS on patient and evaluator global assessment among multiple clinical variables. METHODS We used the central sensitisation inventory (CSI) and short-form McGill pain questionnaire to evaluate CSS and characteristics of pain in 240 outpatients with RA. Disease activity, fibromyalgia, neuropathic pain, anxiety, depression, pain catastrophising, and health-related quality of life were evaluated. We used multivariate analysis to analyse the characteristics of CS-related pain according to CSI and the effect of CSS on patient global assessment (PGA), evaluator global assessment (EGA), and PGA minus EGA among relevant clinical variables. RESULTS In patients with RA, the main descriptors of pain according to severity of CSI scores were "sharp" and "stabbing", whereas those of pain according to disease activity were "tender" and "throbbing". CSS was associated with EGA (p=0.000, β=- 0.199) and PGA minus EGA (p=0.021, β=0.147), but not with PGA. CONCLUSIONS In patients with RA, descriptors for CS-related pain differ from those for disease activity-related pain. CSS may have an important impact on EGA and PGA minus EGA. Additionally, CSI may be helpful in identifying why there is discordance between PGA and EGA.

Abstract
Rheumatoid arthritis (RA) is an inflammatory disease characterized by a variety of symptoms and pathologies often presenting with polyarthritis. The primary symptom in the initial stage is joint swelling due to synovitis. With disease progression, cartilage and bone are affected to cause joint deformities. Advanced osteoarticular destruction and deformation can cause irreversible physical disabilities. Physical disabilities not only deteriorate patients’ quality of life but also have substantial medical economic effects on society. Therefore, prevention of the progression of osteoarticular destruction and deformation is an important task. Recent studies have progressively improved our understanding of the molecular mechanism by which synovitis caused by immune disorders results in activation of osteoclasts; activated osteoclasts in turn cause bone destruction and para-articular osteoporosis. In this paper, we review the mechanisms of bone metabolism under physiological and RA conditions, and we describe the effects of therapeutic intervention against RA on bone.

Abstract
Genetic studies have revealed many variant loci that are associated with immune-mediated diseases. To elucidate the disease pathogenesis, it is essential to understand the function of these variants, especially under disease-associated conditions. Here, we performed a large-scale immune cell gene-expression analysis, together with whole-genome sequence analysis. Our dataset consists of 28 distinct immune cell subsets from 337 patients diagnosed with 10 categories of immune-mediated diseases and 79 healthy volunteers. Our dataset captured distinctive gene-expression profiles across immune cell types and diseases. Expression quantitative trait loci (eQTL) analysis revealed dynamic variations of eQTL effects in the context of immunological conditions, as well as cell types. These cell-type-specific and context-dependent eQTLs showed significant enrichment in immune disease-associated genetic variants, and they implicated the disease-relevant cell types, genes, and environment. This atlas deepens our understanding of the immunogenetic functions of disease-associated variants under in vivo disease conditions.

Abstract
Background Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic synovitis and bone destruction at the joints, causing pain and motor disturbance. Despite the better control of inflammation and joint deformity afforded by modern disease-modifying anti-rheumatic drugs, many patients with RA remain dissatisfied with their treatment, primarily because of sensory-emotional distress. Pre-clinical tests that can evaluate not only the symptoms of arthritis but also the associated pain as sensory-emotional experience are urgently needed. Methods Here, we introduce two types of novel methods for evaluation of voluntary behavior in a commonly used model of RA (collagen-induced arthritis; CIA) in male mice. First, spontaneous motor activity was assessed with a running wheel placed in home cages and the number of rotations was continuously recorded in a 12:12-h light environment. Second, temperature preference was assessed by measuring the time spent in either of the floor plates with augmenting (25 to 49 °C) or fixed temperature (25 °C). We also evaluated the effects of tofacitinib on CIA-associated changes in voluntary wheel running and temperature preference. Results We detected a significant decrease in voluntary wheel running, a significant shift in the distribution of movement in the dark phase, and a significant increase in the time spent in warmer environments than the room temperature in the mice with CIA. These alterations in voluntary behavior have never been described with conventional methods. We also revealed tofacitinib-resistant significant changes in the voluntary behavior and choice of temperature despite significant mitigation of the symptoms of arthritis. Conclusions We described for the first time significant alterations of the voluntary behavior of the mice with CIA during the clinical periods, indicating that the overall physical/motivational states and its circadian variation, as well as the specific preference to a certain environmental temperature, are modified in the mice with CIA, as observed in human patients. Some of these did not parallel with the conventional arthritis scores, particularly during the pharmacotherapy suggesting that mice with CIA show not only the peripheral symptoms but also the central consequences. The use of these approaches would also help clarify the biological mechanisms underlying physician-patient discordance in the assessment of RA.

Abstract
Objectives: Rheumatoid arthritis (RA) pain is thought to be nociceptive. However, recent studies indicate that RA also involves the neuropathic pain (NP) mechanism. We examined pain features and the effect of NP-like symptoms on health-related quality of life (HRQOL) among patients with RA.Methods: The painDETECT questionnaire (PDQ) was used to evaluate NP-like symptoms among 145 outpatients with RA. Disease activity, pain quality, and HRQOL were evaluated. We compared clinical parameters between patients with and without NP-like symptoms and analyzed pain features and the effect of NP-like symptoms on HRQOL, along with multiple other pain-related parameters.Results: Thirty (20.7%) patients had NP-like symptoms (PDQ ≥13). Patient global assessment and evaluator global assessment diverged for patients with RA who had NP-like symptoms. Of the examined pain-related parameters, PDQ score (p = .038, ß = -.173) was associated with the Short-Form 36-Item Health Survey role-social component summary score, but not with the physical or mental component summary scores.Conclusion: NP-like symptoms affected HRQOL among patients with RA. There was discordance between global assessments by patients and by evaluators for patients with RA who had NP-like symptoms. Therefore, NP-like symptoms should be given somewhat more attention when treating patients with RA.

Abstract
AIM Telomere is a component of chromosomes that protects their ends from various stresses. The telomeres shorten during cell division, and their length is maintained by telomerase. The telomerase activity of lymphocytes was shown to be upregulated on lymphocyte activation, and abatacept was found to suppress the activation of T lymphocytes involved in pathogenesis of rheumatoid arthritis. Therefore, we investigated the effect of abatacept on lymphocyte telomerase activity in patients with rheumatoid arthritis. METHOD This study included 11 patients diagnosed with rheumatoid arthritis based on American College of Rheumatology 2010 criteria, who received abatacept treatment from August 2012 to August 2013. We collected their clinical data and obtained peripheral blood samples before starting abatacept, and 1, 3, 6, and 12 months after treatment. Peripheral blood mononuclear cells were extracted using Ficoll density gradient centrifugation, and T and B lymphocytes were sorted by magnetic beads. The telomerase activity of lymphocytes was determined using the telomeric repeat amplification protocol. RESULTS The telomerase activity of T lymphocytes declined from 0.357 to 0.161 (P < 0.01) at 12 months after abatacept treatment, and that of B lymphocytes declined from 0.554 to 0.202 (P < 0.01). The telomerase activity of B lymphocytes, but not that of T lymphocytes, was also significantly downregulated 1 month after treatment. CONCLUSION Abatacept suppressed the telomerase activity of both T and B lymphocytes, although that of B lymphocytes was downregulated before T lymphocytes. These findings imply that the clinical efficacy of abatacept during the early phase depends on the suppression of B lymphocytes.

Abstract
Objective To define the characteristic findings on MRI of skeletal muscles in patients with dermatomyositis (DM) relative to those in patients with other idiopathic inflammatory myopathies (IIMs) and to assess their diagnostic performance in DM. Methods Thirty-six patients with DM, 17 patients with amyopathic DM, 19 patients with polymyositis and 16 patients with non-IIM classified by the 2017 European League Against Rheumatism/American College of Rheumatology criteria were included in this study. The following MRI findings (short-tau inversion recovery [STIR] and gadolinium-enhanced fat-suppressed T1-weighted imaging [Gd-T1WI]) for proximal limb muscles were compared between the disease groups and between myositis-specific autoantibodies/myositis-associated autoantibodies (MSAs/MAAs)-positive and MSAs/MAAs-negative groups: structures with high signal intensity (HSI) (subcutaneous, fascia, muscle); distributions of HSI areas in muscle (diffuse, patchy, peripheral) and patterns of HSI in muscle (honeycomb, foggy, strong HSI). Univariate, multivariate and receiver-operating characteristic [ROC] analyses were performed to assess the diagnostic performance of MRI in DM. Results The characteristic MRI findings in patients with DM were subcutaneous HSI, fascial HSI, peripheral distribution and honeycomb pattern. The MRI findings in the MSAs/MAAs-positive group included more frequent fascial HSI but less frequent foggy pattern compared with the MSAs/MAAs-negative group. Likelihood of DM score ≥ 3 (obtained by counting the number of characteristic MRI findings in patients with DM) showed good diagnostic performance in DM (STIR: sensitivity 72.2%, specificity 88.5%, area under ROC curve [AUC] 84.9%; Gd-T1WI: sensitivity 81.2%, specificity 91.5%, AUC 89.9%). Conclusion The characteristic MRI findings of skeletal muscles can predict patients with DM as well as patients with MSAs/MAAs.

Abstract
Background We previously demonstrated that fasciitis is a common lesion in dermatomyositis (DM) and that DM-associated fasciitis is detectable, as the result of the increased vascularity in the fascia, by power Doppler ultrasonography. We aimed to investigate whether angiogenesis and vascular endothelial growth factor (VEGF)-expressing cells in the fascia are histologically demonstrated during the early phase of DM, and whether inflammation is involved in angiogenesis and an increased number of VEGF-expressing cells. Methods We prospectively evaluated 22 patients with DM and 11 patients with polymyositis (PM). Immunohistochemical staining for CD31, VEGF, and tumor necrosis factor-α (TNF-α) were performed on paraffin-embedded sections. The total vascular inflammation score (TVIS), angiogenesis score (AS), and numbers of VEGF-expressing and TNF-α-expressing cells were analyzed in the fascia and muscle. Results Significant fasciitis was detected in most of the patients DM with or without myositis-specific/associated antibodies, while mild fasciitis was detected in four patients with PM, two of whom were positive for anti-aminoacyl-tRNA synthetase (anti-ARS) antibodies. The AS and the number of VEGF-expressing cells in the fascia of patients with DM were significantly greater than those of patients with PM; no significant difference was observed in muscle in patients with DM and PM. The number of VEGF-expressing cells in the fascia correlated with the AS of DM patients. In early-phase DM, the AS, the number of VEGF-expressing cells, and the TVIS in the fascia were significantly higher than in muscle. However, no significant differences were observed in these scores excluding the TVIS between muscle and the fascia in late-phase DM. In DM patients, the TVIS correlated with the AS in the fascia, while the number of TNF-α-expressing cells correlated with the TVIS and the number of VEGF-expressing cells in the fascia. Conclusion Angiogenesis, the number of VEGF-expressing cells, and the degree of inflammation were higher in the fascia in DM than in PM, and were increased predominantly in the fascia rather than in the muscle in early-phase DM. The degree of inflammation correlated with that of angiogenesis in the fascia of DM. The fascia can therefore be a primary site of inflammation and angiogenesis in the pathogenesis of DM.

Abstract
OBJECTIVE To determine the association between fasciitis and the clinical variables in patients with dermatomyositis (DM) and polymyositis (PM). METHODS We retrospectively reviewed the medical records of 32 patients (24 DM, 8 PM) with newly diagnosed DM and PM and in whom fascia and muscle specimens were histopathologically examined. The relationship between fasciitis and the clinical variables was statistically analyzed. These included age, sex, myalgia, muscle weakness, creatine kinase (CK) and aldolase activities, anti-Jo1 antibody, interstitial lung disease, and malignancy. RESULTS Twenty (62.5%) of the 32 patients who underwent the histopathological examination of a fascia specimen had fasciitis, including 18 (75%) of 24 patients with DM and 2 (25%) of 8 patients with PM. The frequency of fasciitis was significantly higher among the patients with DM than among the patients with PM (p < 0.05). Histopathologically, fasciitis in PM was very mild in comparison to that in DM. The frequency of myalgia in patients with fasciitis was significantly higher than that in patients without fasciitis (p < 0.05). However, myalgia was not associated with myositis. There were no significant differences in the patients with and without fasciitis in age, sex, manual muscle test 8 scores, CK or aldolase activities, or the presence of anti-Jo1 antibodies and malignancy. CONCLUSION The frequency of fasciitis was significantly higher among patients with DM than among those with PM. Fasciitis, rather than myositis, was associated with myalgia.

Abstract
BACKGROUND Prokineticin 2 (PK2) expression is upregulated in mice with collagen-induced arthritis (CIA), an animal model of rheumatoid arthritis. The purpose of our study was to investigate the effects of PK2 inhibition on CIA. METHODS PK2, prokineticin receptor (PKR) 1, and PKR2 mRNA transcripts in the joints of CIA mice were measured by real-time PCR on Days 21, 28, and 35 (n = 15/day). Localization of PKR1 and PKR2 proteins was examined immunohistochemically. PKRA7, a PK2 antagonist, was administered intraperitoneally for 2 weeks to CIA mice, and the severity of arthritis was compared between treated (n = 12) and untreated (n = 12) mice. The gene expression levels of inflammatory cytokines IL-1β, IL-6, TNF-α, and VEGF were also measured by real-time PCR and compared between treated (n = 6) and untreated (n = 6) CIA mice. The data was statistically analyzed, and P values of less than 0.05 were considered significant. RESULTS In the thickened synovial membrane, PKR1 protein was expressed in infiltrating neutrophils, while PKR2 expression was found in macrophage-like mononuclear cells. PK2 gene expression was significantly more pronounced on Days 28 and 35 than on Day 21 (2.15 and 2.03 versus 1.00, P = 0.0311 and 0.0247; Dunn's multiple comparison). PKR2 gene expression levels were significantly higher on Days 28 and 35 compared to Day 21 (25.4 and 39.3 versus 1.0, P = 0.002 and < 0.0001; Dunn's multiple comparison). Administration of PKRA7 suppressed the severity of arthritis (P < 0.001; two-way analysis of variance). A gene expression analysis of inflammatory cytokines revealed significantly reduced IL-1β and lL-6 expression in the joints of PKRA7-treated mice compared to untreated mice (0.1 versus 1.0, P = 0.0043 and 0.04 versus 1.0, P = 0.0022, respectively; Mann-Whitney test). CONCLUSIONS PK2 inhibition suppressed arthritis in mice with CIA.

Abstract
We report a 39-year-old female admitted for fever. She showed physical findings of bilateral granulomatous uveitis, swelling of the bilateral parotid glands, and paralysis of the left second branch of the trigeminal nerve. Her chest X-ray showed evidence of bilateral hilar lymphadenopathy. We performed biopsy of her parotid gland, and leading to a diagnosis of noncaseating epithelioid granuloma characterized by lymphocyte and multinucleated giant cell invasion. Therefore, she was diagnosed with the abortive type of Heerfordt syndrome which is a subtype of sarcoidosis. This is the only case associated with paralysis of the trigeminal nerve without paralysis of facial nerves to be reported in Japan.

Abstract
OBJECTIVES The purpose of this study was to confirm the inhibitory effects of sunitinib, an angiogenesis inhibitor that targets tyrosine kinases of vascular endothelial growth factor receptor (VEGFR) family and platelet-derived growth factor receptor (PDGFR) family, on arthritis in mice with type II collagen-induced arthritis (CIA). METHODS Sunitinib at a concentration of 30 or 60 mg/kg/day was intraperitoneally administered to mice with CIA. We compared the changes in arthritis score over time, pathological score, bone density, and microvascular density in synovial membrane between the vehicle and treatment groups. RESULTS In the sunitinib-treated groups, the arthritis score decreased in a dose-dependent manner in comparison with that in the vehicle group. Furthermore, improvement in the pathological score, inhibitory tendency of loss in the bone density, and a decrease in the synovial microvascular density were also observed in the sunitinib-treated groups. CONCLUSIONS Sunitinib remarkably inhibited arthritis, particularly synovial angiogenesis in a murine CIA model. This compound may be useful for treating arthritis.

Abstract
AIMS To determine the sensitivity and specificity of the photopic negative response (PhNR) of the focal electroretinograms (ERG; focal PhNR) to detect glaucomatous eyes with different degrees of visual field defects. METHODS One-hundred and fourteen eyes of 114 patients with open angle glaucoma and 42 eyes of 42 normal controls were studied. The focal ERGs were elicited by a 15 degrees stimulus spot centred on the macula, and on the supero-temporal and on the infero-temporal areas of the macula. The receiver operating characteristic curves were determined to obtain optimal cut-off values. Eyes were classified as being glaucomatous when their focal PhNRs were less than the cut-off values in either retinal area (combined criterion). RESULTS The focal PhNR amplitudes were significantly reduced with an advance in the stage of glaucoma. In early glaucoma, the sensitivities of the PhNR measured for each retinal area ranged from 58.1% to 80.7%. The sensitivities were significantly increased to 90.6% and 96.9% for the focal PhNR amplitude and the focal PhNR/b-wave amplitude ratio, respectively, when the combined criterion was employed. The specificity was >90%. CONCLUSIONS Focal PhNRs have diagnostic ability in detecting early glaucoma with high sensitivity and specificity, especially when the combined criterion is used.

Abstract
Background Bombina variegate peptide 8 (Bv8) is a small protein secreted by frog skin. Recently it has been shown to contribute to tumor angiogenesis in mouse model. The purpose of this study was to investigate Bv8 in mice with type II collagen-induced arthritis (CIA). Methods We induced CIA in male DBA/1J mice. The severity of arthritis was evaluated based on an arthritis score. RNA was extracted from the joint, and examined for Bv8 mRNA expression by RT-PCR and real-time RT-PCR. Synovial tissue and bone marrow were immunohistochemically examined using anti-Bv8 antibody. Results The level of Bv8 mRNA expression in the joint was below the detection limit in the control group, but was elevated in the CIA group, and was correlated with the arthritis score. In addition, an increase in Bv8-positive cells was observed in the synovium and bone marrow in the CIA group. Conclusion Bv8 was elevated in the synovium and bone marrow of CIA mice, suggesting that Bv8 plays an important role in the pathogenesis of arthritis.

Abstract
Systemic lupus erythematosus (SLE) patients have a decreased number of peripheral blood T cells containing signal-joint T cell receptor excision circles (Sj TRECs), which are considered an indicator of thymic output. The objective of this study was to investigate the mechanism of the decrease in such T cells. Peripheral blood T cells from SLE patients were classified into CD4+ and CD8+ cells. Sj TREC levels were measured by real-time PCR. Telomerase activity was determined by the telomeric repeat amplification protocol assay. The numbers of Sj TREC containing CD4+ and CD8+ cells were lower in the peripheral blood of SLE patients than in the controls. A correlation was found between the numbers of Sj TREC-positive CD4+ and CD8+ cells. The level of TRECs is influenced by an increase in cell division. To examine this increase, telomerase activity as an indicator of cell division was measured simultaneously; however, there was no correlation between the Sj TREC level and telomerase activity. These results suggest that decreased thymic output occurs in SLE patients.

Abstract
A 33-year-old woman complaining of severe anemia was admitted to our hospital for polyclonal hyperglobulinemia. She was diagnosed with pure red cell aplasia (PRCA) associated with Evans syndrome. Initially, the presence of human parvovirus B19 (HPV B19) IgM appeared to indicate that the cause of PRCA was HPV B19 infection. Evans syndrome improved with steroid therapy, but PRCA was refractory. Cyclosporine was administered; consequently, the patient markedly recovered from PRCA and was discharged. PRCA complicated by Evans syndrome occurred during the course of polyclonal hyperglobulinemia. The most direct etiology for the onset of PRCA was unclear; however, immunological disorders such as polyclonal hyperglobulinemia, in addition to HPV B19 infection, may have been partly responsible for the etiology of PRCA.

Abstract
We report two patients with adult Still's disease with an abnormally high level of telomerase activity. The first patient was a 61-year-old woman. The mean telomerase activity value for peripheral blood mononuclear cells of healthy adults measured by our method was 0.13 +/- 0.03, whereas that in this patient during the active phase was abnormally high, at more than 27.56. The patient was treated by steroid therapy and successfully brought into remission, during which the telomerase activity value for peripheral blood mononuclear cells was reduced to 2.22. The second patient was a 19-year-old man. Although he stayed in remission after steroid therapy, a reduction in the steroid dose resulted in recrudescence, at which time the telomerase activity value peripheral blood mononuclear cells was high, at 11.76. Elevated levels of telomerase activity have been reported in patients with various pathological conditions other than malignant tumors. However, our literature search failed to reveal a report on such a high level of telomerase activity in association with a benign disease.

Abstract
T-cell telomerase activity was high in the active and inactive stages of systemic lupus erythematosus (SLE). In contrast, B-cell telomerase activity was very high only in the active stage. Compared with normal subjects, SLE patients had a shorter T-cell telomere, but their B-cell telomere length did not differ from that of normal subjects. These findings suggest that T cells are always activated, and that the manifestation of the disease requires the activation of not only T but also B cells. B-cell inhibition alone may be sufficient to suppress the clinical symptoms of SLE, but we consider that the essential treatment of SLE should target T cells as well. In recent years, various biologicals have begun to be used for the treatment of SLE. It is interesting how the use of such biologicals in the future will change T- and B-cell telomerase activity. In formulating a therapeutic strategy using biologicals for SLE, the measurement of telomerase activity in T and B cells seems useful for the preparation of target cells, selection of therapeutic drugs, and evaluation of therapeutic responses.
