    The presence of antiendothelial cell antibodies (AECAs) has been documented in Takayasu arteritis (TAK), a chronic granulomatous vasculitis. Here, we identify cell-surface autoantigens using an expression cloning system. A cDNA library of endothelial cells is retrovirally transfected into a rat myeloma cell line from which AECA-positive clones are sorted with flow cytometry. Four distinct AECA-positive clones are isolated, and endothelial protein C receptor (EPCR) and scavenger receptor class B type 1 (SR-BI) are identified as endothelial autoantigens. Autoantibodies against EPCR and SR-BI are detected in 34.6% and 36.5% of cases, respectively, with minimal overlap (3.8%). Autoantibodies against EPCR are also detected in ulcerative colitis, the frequent comorbidity of TAK. In mechanistic studies, EPCR and SR-BI function as negative regulators of endothelial activation. EPCR has also an effect on human T cells and impair Th17 differentiation. Autoantibodies against EPCR and SR-BI block the functions of their targets, thereby promoting pro-inflammatory phenotype.

    Autoantibodies against integral membrane proteins are usually pathogenic. Although anti-endothelial cell antibodies (AECAs) are considered to be critical, especially for vascular lesions in collagen diseases, most molecules identified as autoantigens for AECAs are localized within the cell and not expressed on the cell surface. For identification of autoantigens, proteomics and expression library analyses have been performed for many years with some success. To specifically target cell-surface molecules in identification of autoantigens, we constructed a serological identification system for autoantigens using a retroviral vector and flow cytometry (SARF). Here, we present an overview of recent research in AECAs and their target molecules and discuss the principle and the application of SARF. Using SARF, we successfully identified three different membrane proteins: fibronectin leucine-rich transmembrane protein 2 (FLRT2) from patients with systemic lupus erythematosus (SLE), intercellular adhesion molecule 1 (ICAM-1) from a patient with rheumatoid arthritis, and Pk (Gb3/CD77) from an SLE patient with hemolytic anemia, as targets for AECAs. SARF is useful for specific identification of autoantigens expressed on the cell surface, and identification of such interactions of the cell-surface autoantigens and pathogenic autoantibodies may enable the development of more specific intervention strategies in autoimmune diseases.

    OBJECTIVES: Systemic sclerosis is characterised by ischaemic skin ulcers on the fingertips, and low-energy shock wave therapy is suggested as a novel treatment for ischaemic lesions with angiogenic effects. We aimed to investigate the efficacy and safety of shock wave therapy for skin ulcers in patients with systemic sclerosis. METHODS: In this phase 3 pivotal study, we analysed 60 systemic sclerosis patients with digital ulcers that did not disappear after >4 weeks of existing treatment: 30 patients were treated with extracorporeal shock wave therapy and 30 with conventional treatment. The ulcer count reduction observed after an 8-week treatment period was compared between the shock wave therapy and conventional treatment groups. RESULTS: After an 8-week treatment period, the mean reduction in the number of ulcers was 0.83 (standard deviation [SD] 2.79) in the conventional treatment group compared to a more pronounced reduction of 4.47 (SD 2.65) in the shock wave therapy group. CONCLUSIONS: The study findings indicate the efficacy of extracorporeal shock wave therapy for refractory digital ulcers associated with systemic sclerosis, which has limited therapeutic options. This therapy is non-invasive and safe and can be used without restriction in combination with other therapies, thus serving as a novel therapeutic method.

    Enthesitis is a characteristic manifestation of spondyloarthropathy (SpA). Historically, Behçet's syndrome (BS) was classified within SpA. Although they are now classified separately, the association between BS and SpA remains controversial. The concept of MHC-I (major histocompatibility complex class I)-opathy has been proposed based on the overlap in immunopathological mechanisms among diseases associated with human leukocyte antigen (HLA) class I. Enthesitis is a frequent complication in patients with BS who also have acne and arthritis. However, information regarding enthesitis in patients with BS without arthritis (BS-WA) is limited. Herein, we report a case of vascular BS complicated by enthesitis. In this case, heel pain was the dominant symptom at presentation. Laboratory tests revealed chlamydia antibody positivity, leading to a tentative diagnosis of reactive arthritis. Despite treatment, C-reactive protein (CRP) levels remained elevated. Imaging revealed numerous aneurysmal lesions in the large vessels. Based on these findings and other symptoms, patient was diagnosed with vascular BS. He tested positive for HLA-B15 and HLA-B46, which are associated with peripheral SpA. Subsequent remission induction therapy for BS was effective and the patient was discharged without complications. Our case and a literature review suggest that there exists a subgroup of BS-WA with a complication of enthesitis, possibly belonging to the spectrum of MHC-I-opathies. It is important to consider BS as a differential diagnosis in patients presenting with enthesitis and to conduct a precise medical history review regarding the symptoms of BS.

    Dermatomyositis (DM) is associated with interstitial lung disease (ILD) and malignancy. However, the coexistence of ILD and malignancy (DM-ILD-malignancy) is rare, and limited information exists regarding its management. Herein, we report the case of a 70-year-old man who developed DM with rapidly progressive ILD and advanced gastric cancer and provide a literature review of managing DM-ILD-malignancy. The patient presented with typical DM skin rashes and shortness of breath, which worsened within 1 month, without muscular symptoms. Additionally, the patient tested negative for myositis-specific autoantibodies (MSAs). Computed tomography revealed ILD and advanced gastric cancer, which was confirmed on endoscopic examination to be a poorly differentiated adenocarcinoma. Although the patient's ILD progressed rapidly, surgical treatment of the cancer was prioritized. Prednisolone (PSL) 0.5 mg/kg was initiated 3 days before surgery and increased to 1 mg/kg at 7 days postoperative. Remarkable improvement in the skin rash and ILD was observed, and the PSL dose was tapered without immunosuppressants. A literature review revealed that anti-melanoma differentiation-associated gene 5 and anti-aminoacyl transfer RNA synthetase antibodies are the predominant MSAs in DM-ILD-malignancy, and the optimal treatment should be determined based on several factors, including ILD patterns, and malignancy type and stage. In particular, lung cancer may be a risk factor for the acute exacerbation of ILD, and preceding immunosuppression would be useful. Furthermore, prioritizing surgery for gastric cancer is effective because of its paraneoplastic nature.

    The induction of autoimmune diseases during tumour necrosis factor-alpha inhibitor (TNFi) usage has been described. Herein, we report a rare case of a 49-year-old woman with antimelanoma differentiation-associated gene 5 (MDA5) antibody (Ab)-positive dermatomyositis (DM), which developed 5 weeks after the introduction of an etanercept biosimilar to rheumatoid arthritis (RA). Four of the five known cases, including ours, of anti-MDA5Ab-positive DM complicated with RA revealed anti-MDA5Ab-positive DM following TNFi usage. When patients with RA are diagnosed with interstitial lung disease during TNFi usage, anti-MDA5 Ab-positive DM could be a differential diagnosis.

    OBJECTIVES: The feasibility of corticosteroid withdrawal (CW) for Takayasu arteritis (TAK) remains uncertain. Two autoantibodies (Abs) are identified against endothelial protein C receptor (EPCR) and scavenger receptor class B type 1 (SR-BI) in TAK, determining its three subgroups. This study aimed to evaluate CW using tocilizumab (TCZ) and its association with the Ab profile. METHODS: This prospective study, lasted for 24 weeks, included patients with relapsed but stable TAK. Scheduled tapering of prednisolone (PSL) was performed with subcutaneous TCZ (CW at week 20). The primary endpoint was the difference in type A remission, defined by CW and the absence of inflammatory signs, according to the Ab profile at week 24. RESULTS: Twenty patients were included and 18 patients with a mean PSL dose of 4.9 ± 2.8 mg/day were analysed. Anti-EPCR Ab-positive (E+), anti-SR-BI Ab-positive (S+), and double-negative (DN) groups included four (22.2%), eight (44.4%), and six (33.3%) patients, respectively. At week 24, the mean PSL dose was 2.0 ± 2.7 mg/day. Type A remission was observed in eight patients (44.4%), with significant differences based on the Ab profile: E+ (three patients, 75%), S+ (five patients, 62.5%), and DN (zero patients, 0%) (P=0.018). Besides, age, disease duration, PSL dose, type V arterial lesion, arterial dilation, and C-reactive protein >0.01 mg/dL were identified as risks for CW failure. CONCLUSION: CW using TCZ was achieved in 44.4% of patients with TAK relapse and was significantly higher in E+ and S+ patients. CW can be a feasible target, and the precise selection of patients is critical.

    BACKGROUND: In systemic lupus erythematosus (SLE), autoreactive B cells are thought to develop by-passing immune checkpoints and contribute to its pathogenesis. Toll-like receptor (TLR) 7 and 9 signaling have been implicated in their development and differentiation. Although some B cell subpopulations such as T-bet + double negative 2 (DN2) cells have been identified as autoreactive in the past few years, because the upregulated surface markers of those cells are not exclusive to them, it is still challenging to specifically target autoreactive B cells in SLE patients. METHODS: Our preliminary expression analysis revealed that phospholipase D4 (PLD4) is exclusively expressed in plasmacytoid dendritic cells (pDCs) and B cells in peripheral blood mononuclear cells (PBMCs) samples. Monoclonal antibodies against human PLD4 were generated, and flow cytometry analyses were conducted for PBMCs from 23 healthy donors (HDs) and 40 patients with SLE. In vitro cell culture was also performed to study the conditions that induce PLD4 in B cells from HDs. Finally, recombinant antibodies were synthesized from subpopulations of PLD4 + B cells from a patient with SLE, and their antinuclear activity was measured through enzyme-linked immunosorbent assay. RESULTS: pDCs from both groups showed comparable frequency of surface PLD4 expression. PLD4 + B cells accounted for only a few percent of HD B cells, whereas they were significantly expanded in patients with SLE (2.1% ± 0.4% vs. 10.8% ± 1.2%, P < 0.005). A subpopulation within PLD4 + B cells whose cell size was comparable to CD38 + CD43 + plasmablasts was defined as "PLD4 + blasts," and their frequencies were significantly correlated with those of plasmablasts (P < 0.005). PLD4 + blasts phenotypically overlapped with double negative 2 (DN2) cells, and, in line with this, their frequencies were significantly correlated with several clinical markers of SLE. In vitro assay using healthy PBMCs demonstrated that TLR7 or TLR9 stimulation was sufficient to induce PLD4 on the surface of the B cells. Finally, two out of three recombinant antibodies synthesized from PLD4 + blasts showed antinuclear activity. CONCLUSION: PLD4 + B cells, especially "blastic" ones, are likely autoreactive B cells undergoing TLR stimulation. Therefore, PLD4 is a promising target marker in SLE treatment.

    Macrophage activation syndrome (MAS) is a potentially fatal complication of rheumatic diseases, characterized by activated macrophages with hemophagocytosis and multiple organ damage. We report a case of MAS associated with systemic lupus erythematosus that initially presented with severe liver dysfunction. Although it was improved with steroids and plasmapheresis, severe pancytopenia was subsequently experienced, and the bone marrow showed severe aplasia similar to aplastic anemia. Nevertheless, the administration of immunosuppressants resulted in the recovery of blood counts within two weeks. When severe MAS results in cytokine overproduction, bone marrow aplasia may occur, for which immunosuppressive therapy may be highly effective.

    OBJECTIVES: Methotrexate (MTX) is associated with extensive side effects, including myelosuppression, interstitial pneumonia, and infection. It is, therefore, critical to establish whether its administration is required after achieving remission with tocilizumab (TCZ) and MTX combination therapy in patients with rheumatoid arthritis (RA). Therefore, the aim of this multicenter, observational, cohort study was to evaluate the feasibility of MTX discontinuation for the safety of these patients. METHODS: Patients with RA were administered TCZ, with or without MTX, for 3 years; those who received TCZ+MTX combination therapy were selected. After remission was achieved, MTX was discontinued without flare development in one group (discontinued [DISC] group, n = 33) and continued without flare development in another group (maintain [MAIN] group, n = 37). The clinical efficacy of TCZ+MTX therapy, patient background characteristics, and adverse events were compared between groups. RESULTS: The disease activity score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) at 3, 6, and 9 months was significantly lower in the DISC group (P < .05, P < .01, and P < .01, respectively). Further, the DAS28-ESR remission rate at 6 and 9 months and Boolean remission rate at 6 months were significantly higher in the DISC group (P < .01 for all). Disease duration was significantly longer in the DISC group (P < .05). Furthermore, the number of patients with stage 4 RA was significantly higher in the DISC group (P < .01). CONCLUSIONS: Once remission was achieved, MTX was discontinued in patients who responded favorably to TCZ+MTX therapy, despite the prolonged disease duration and stage progression.

    OBJECTIVES: Anti-melanoma differentiation-associated protein-5 (MDA5) autoantibodies (Abs) are associated with rapidly progressive interstitial lung disease (RP-ILD) in dermatomyositis (DM). Because the addition of plasma exchange (PE) and rituximab (RTX) to triple therapy is inadequate in severe cases, we treat such cases with intensive induction therapy (IIT) combining all these options with tofacitinib (TOF). In this study, we investigated the poor prognostic factors and the efficacy and safety of IIT. METHODS: Thirty-three patients diagnosed with anti-MDA5 Ab-positive DM in our institution between 2014 and 2021 were included. The clinical characteristics of poor prognosis were retrospectively analysed using principal component analysis (PCA), and the outcomes of IIT were analysed in terms of survival, assessed using the Kaplan-Meier test, and adverse events. RESULTS: Although triple therapy with RTX, PE, or intravenous immunoglobulin was administered before the introduction of IIT, eight of 12 RP-ILD cases with a ferritin level >400 ng/mL (mean, 2,342) died within a median of 2.5 months. PCA revealed distinct clusters for prognosis, and age and serum ferritin were leading predictors of the prognosis. IIT, consisting of combinations of triple therapy with higher doses of methylprednisolone, PE, RTX, and TOF, was applied to eight patients (mean ferritin, 3,558). Although two patients died even with these regimens, a significant improvement in survival was documented. Several IIT-related adverse events were observed, including viral and fungal infections and cytopenia. CONCLUSIONS: IIT significantly improved the survival of patients with severe anti-MDA5 Ab-positive RP-ILD. Although infections are noted, their benefits outweigh the risks in younger patients with high serum ferritin levels.

    There have been many reports on serologic autoantibodies in inflammatory bowel diseases (IBD),1 consisting of ulcerative colitis (UC) and Crohn's disease (CD), and recently Kuwada et al2 reported a new autoantibody against integrin αvβ6 with high sensitivity and specificity for UC. Concurrently, we had discovered autoantibodies against endothelial protein C receptor (EPCR) in Takayasu arteritis (TAK), which is sometimes complicated by UC.3 Interestingly, this autoantibody was found in most patients with TAK associated with UC, and we found that the positivity rate in patients with UC without TAK was also high, suggesting that anti-EPCR antibody is a candidate autoantibody useful for the diagnosis of UC.4 To clarify the diagnostic usefulness of anti-EPCR antibodies in patients with IBD and their relationship to several disease subphenotypes and their disease activities, we analyzed the serum samples from patients with IBD and non-IBD control subjects in Japan and the United States.

    Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the production of various autoantibodies and deposition of immune complexes on tissues. Acquired thrombotic thrombocytopenic purpura (TTP) is a life-threatening hematological disorder that rarely develops in SLE, mainly caused by inhibitory or clearing autoantibody against ADAMTS13. Although B cells play critical roles in the pathogenesis of two diseases, the role of B-cell depletion therapy using rituximab (RTX), a chimeric monoclonal antibody targeting CD20, in the management of TTP associated with SLE remains unclear. We present a 27-year-old woman who manifested TTP and nephritis simultaneously at diagnosis of SLE. This patient successfully responded to high-dose glucocorticoids combined with plasma exchange, and early administration of RTX-induced sustained remission of TTP without relapse over 16 months. This literature review in light of our case demonstrates relationship between early intervention with RTX and better treatment response despite the degree of ADAMTS13 activity. Moreover, we discuss the clinical features in TTP associated with SLE, risk factors for the development of TTP in SLE, and possible outcomes based on RTX dose. It is important to consider upfront RTX as a promising treatment strategy for SLE-associated secondary TTP to improve short-term response and long-term prognosis.

    Although Takayasu arteritis (TAK) is a form of large vessel vasculitis, complications of glomerulonephritis have occasionally been observed, with mesangial proliferative glomerulonephritis as the most common. The aim of this work was to present a case-based review regarding the association of glomerulonephritis and IgA nephropathy (IgAN) with TAK. A literature search was carried out using the PubMed and Scopus databases for articles published in English, and the Ichu-shi Web for Japanese. A 34-year-old Japanese man was evaluated for proteinuria, and IgAN was diagnosed by renal biopsy. Simultaneously, aortic wall thickening and right renal artery stenosis confirmed a coexisting TAK. Prednisolone and methotrexate improved both diseases, and percutaneous transluminal renal angioplasty resulted in right renal artery reopening. Our case and literature review revealed that membranous proliferative glomerulonephritis and IgAN are common in eastern Asia, while focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis are common in other regions. The incidence of IgAN is higher in TAK cases and is mostly reported in Asia. Abdominal aortic involvement and renal artery stenosis are common in cases with preceding TAK. IgAN could be related to the cytokine network involving interleukin-6, suggesting the usefulness of tocilizumab in patients with TAK accompanied by IgAN. The type of glomerulonephritis complicated with TAK differs among regions, and patients with TAK are more likely to experience IgAN than the healthy population.

    We report the first case of proteinase 3 (PR3)- antineutrophil cytoplasmic antibody (ANCA)-positive granulomatosis with polyangiitis (GPA) with predominant ears, nose, and throat (ENT) manifestations following COVID-19 vaccination. A 63-year-old woman presented with aural fullness three days after vaccination. She presented with progressive rhinosinusitis and otitis media leading to profound hearing loss within three weeks. Clinical imaging revealed soft-tissue shadows in the paranasal sinuses with multiple pulmonary nodules, and histopathology was consistent with a diagnosis of GPA. It is crucial to be wary of the possibility of GPA in patients who received COVID-19 vaccines due to its rapid disease progression.

    Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic autoimmune disorder classified under anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, predominantly affecting small- to medium-sized vessels, characterized by asthma, eosinophilia, and necrotizing granulomatous inflammation. Most patients with EGPA experience peripheral neuropathy, whereas intracerebral hemorrhage is rare as EGPA-related presentation in central nervous system involvement, causing severe morbidity and mortality. Here, we present a 45-year-old man with refractory EGPA who developed intracerebral hemorrhage as the first manifestation, followed by cardiac involvement. This patient with a history of bronchial asthma developed a right putaminal hemorrhage caused by EGPA. Although intravenous cyclophosphamide (IVCY) and mepolizumab (MPZ) induced remission, relapse was frequently observed. Subsequently, he developed cardiomyopathy despite administration of rituximab (RTX) substituted from IVCY and MPZ. Combined immunosuppressive therapy, including IVCY, MPZ, and RTX was required to inhibit vascular inflammation, leading to sustained remission. We review previously published literature while focusing on the clinical features of patients with intracerebral hemorrhage caused by EGPA and describe clinical characteristics for detecting EGPA in patients with intracerebral hemorrhage, emphasizing rapid evaluation and recognition of EGPA and adequate intervention in the early vasculitic phase of this disease. We also refer to the immunological aspects of this case. It is important to consider "multi-targeted therapy" through interleukin-5 suppression and B cell depletion in the management of refractory EGPA.

    Sjögren's syndrome manifests with a wide variety of neurologic symptoms. This case report presents a 53-year-old woman with Sjögren's syndrome associated with temporal hemiplegia, which was suspected to be a transient ischemic attack. After induction of immunosuppressive therapies [high-dose prednisolone (1 mg/kg/day) and intravenous cyclophosphamide (total 5 g)], the hemiplegia did not reappear and the blood flow abnormalities remarkably improved as depicted on electroencephalography and single photon emission computed tomography. This case suggests that temporal hemiplegia presenting with transient ischemia-like attack symptoms may be a neurologic manifestation of Sjögren's syndrome and responsive to immunosuppressive therapy.

    LILRB4 (B4, also known as ILT3/CD85k) is an immune checkpoint of myeloid-lineage cells, albeit its mode of function remains obscure. Our recent identification of a common ligand for both human B4 and its murine ortholog gp49B as the fibronectin (FN) N-terminal 30-kDa domain poses the question of how B4/gp49B regulate cellular activity upon recognition of FN in the plasma and/or the extracellular matrix. Since FN in the extracellular matrix is tethered by FN-binding integrins, we hypothesized that B4/gp49B would tether FN in cooperation with integrins on the cell surface, thus they should be in close vicinity to integrins spatially. This scenario suggests a mode of function of B4/gp49B by which the FN-induced signal is regulated. FN pull-down complex was found to contain gp49B and integrin β1 in bone marrow-derived macrophages. The confocal fluorescent signals of the three molecules on the intrinsically FN-tethering macrophages were correlated to each other. When FN-poor macrophages adhered to culture plate, the gp49-integrin β1 signal correlation increased at the focal adhesion, supporting the notion that gp49B and integrin β1 become spatially closer to each other there. While adherence of RAW264.7 and THP-1 cells to immobilized FN induced phosphorylation of spleen tyrosine kinase, whose level was augmented under B4/gp49B deficiency. Thus, we concluded that B4/gp49B can co-tether fibronectin in cooperation with integrin in the cis configuration on the same cell, forming a B4/gp49B-FN-integrin triplet as a regulatory unit of focal adhesion-dependent proinflammatory signal in macrophages.

    Although pregnancy is an important risk factor for autoimmune rheumatic diseases, little is known regarding the association between pregnancy and dermatomyositis (DM) or polymyositis (PM). Herein, we present two patients with DM that developed during the perinatal period. The first patient was positive for anti-aminoacyl synthetase (ARS) antibody and developed DM in the 14th week of pregnancy. Despite treatment, her foetus died of intrauterine growth restriction in the 27th week. The second patient was positive for anti-melanoma differentiation-associated gene 5 (MDA-5) antibody and developed DM 1 week after miscarriage at 9 weeks of gestation. The patient developed severe interstitial pneumonia, and intensive therapy including tofacitinib and rituximab administration was required. Our cases and a literature review revealed that various myositis-specific autoantibodies, including anti-ARS, anti-Mi-2, anti-TIF-1γ, and anti-MDA-5, are associated with DM and PM triggered by pregnancy. We also found that delay in commencing treatment in case of active disease including myositis and interstitial pneumonia, and poor response to corticosteroids were related to poor foetal outcomes in DM and PM. Although rare in pregnant women, it is critical to consider the possibility of DM and PM in patients presenting with rash, fever, weakness, and cough, and testing for myositis-specific autoantibodies is recommended.

    Relapse of Takayasu arteritis (TAK) is frequent, and the use of biologics is required in refractory cases. Tocilizumab (TCZ), a biological agent used in TAK, is known to increase the incidence of diverticulitis in patients with rheumatoid arthritis. Adverse events of TCZ in TAK have been poorly recognised. This study aimed to investigate the occurrence of severe colitis among patients with TAK receiving TCZ. We enrolled 116 patients with TAK who met the criteria of the American College of Rheumatology and visited our department between 2018 and 2020. The occurrence of severe colitis and its clinical characteristics were retrospectively evaluated. TCZ was introduced in 34 of 116 patients (29.3%). Severe colitis that required hospitalisation was observed in three of the 34 patients receiving TCZ (8.8%). All patients were female and had Numano type V artery lesions, and the ascending colon was commonly affected. Wide lesions that reached the sigmoid colon, colonic perforation, bacteraemia, or positive stool cultures were observed in some patients. All patients received antibiotics and intestinal rest, and TCZ was resumed in one patient. IL-6 plays a physiological role in the intestine, including recovery from ischaemic damage. In addition to infectious aetiology, blocking the physiological roles of IL-6 by TCZ is considered important for the development of colitis in TAK. Severe colitis is an important adverse event in patients with TAK who receive TCZ. The risk of bloodstream infection associated with colitis should be recognised, especially in patients who have undergone vascular surgery. Key Points • Severe colitis was observed in 8.8% of patients with TAK receiving tocilizumab • Patients had type V artery lesions and ascending colon involvement and were under long-term use of corticosteroids • Inhibition of the physiological roles of IL-6 in the intestinal tract might also be involved.

    OBJECTIVES: To investigate 6-year drug survival (median: 48.5 months) of golimumab and predictors for lack of efficacy leading to golimumab discontinuation in Japanese patients with rheumatoid arthritis (RA) in routine practice. METHODS: This retrospective single-center study included 60 patients with RA treated with golimumab from November 2011 to August 2020. Patients were divided into 2 groups (retention, n = 28; withdrawal due to lack of efficacy, n = 24). The retention rate was assessed using the Kaplan-Meier method, and variables associated with golimumab discontinuation were identified using the Cox proportional hazard model. RESULTS: The prevalence of concomitant methotrexate and no biologics use was significantly higher in the retention than in the withdrawal group. Overall drug survival of golimumab was 66.3%, 48.3%, and 24.5% at 12, 36, and 72 months, respectively. There were statistical differences in retention rates among groups stratified by initiation dose, methotrexate, and biologics use. Multivariate analysis revealed the factor associated with golimumab discontinuation as history of 1 (hazards ratio: 4.42, 95% CI: 1.35-19.93, P = .012) and ≥2 biologics use (7.49, 1.97-36.27, P = .003). CONCLUSIONS: Prior exposure of increasing number of biologics was identified as the most important factor negatively affecting long-term golimumab retention in Japanese patients with RA.

    Hypertrophic pachymeningitis (HP) presents with thickening of the dura mater in the cerebrum and spine, and its symptoms vary depending on the affected location. The association of HP with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis has been recognized, and most cases are complicated by granulomatosis with polyangiitis. We report the case of a 47-year-old man who presented with HP upon relapse of eosinophilic granulomatosis with polyangiitis (EGPA), with literature review. He presented with disturbance of consciousness, and magnetic resonance imaging (MRI) revealed thickening of the dura mater around the left parietal lobe. Although myeloperoxidase (MPO)-ANCA was positive on EGPA diagnosis, the elevation of MPO-ANCA was not documented at the onset of HP. Brain perfusion scintigraphy showed an increase in blood flow in the left parietal lobe and temporal lobe, and electroencephalogram (EEG) revealed slow waves in the left parietal lobe. He was treated with a high dose of corticosteroid and rituximab, and the slow waves on EEG and brain perfusion were normalized. Although the most frequent symptom of HP is headache, disturbance of consciousness can be the manifestation of HP, and inflammation of HP could affect the cerebral parenchyma, which can be documented as abnormal EEG and perfusion scintigraphy. Literature review revealed that most of the HP in EGPA developed when EGPA relapsed, and was observed in patients with MPO-ANCA positivity. HP develops without evidence of other clinical features of EGPA; therefore, adequate imaging, including contrast-enhanced MRI, is necessary. Rituximab may be effective for treating HP complicated with EGPA.

    BACKGROUND: Although cyclophosphamide (CPA) is the key drug for the treatment of autoimmune diseases including vasculitides, it has some well-known adverse effects, such as myelosuppression, hemorrhagic cystitis, infertility, and infection. However, CPA-associated severe enteritis is a rare adverse effect, and only one case with a lethal clinical course has been reported. Therefore, the appropriate management of patients with CPA-associated severe enteritis is unclear. CASE SUMMARY: We present the case of a 61-year-old woman diagnosed with granulomatosis with polyangiitis based on the presence of symptoms in ear, lung, and, kidney with positive myeloperoxidase-antineutrophil cytoplasmic antibody. She received pulsed methylprednisolone followed by prednisolone 55 mg/d and intravenous CPA at a dose of 500 mg/mo. Ten days after the second course of intravenous CPA, she developed nausea, vomiting, and diarrhea, and was admitted to the hospital. Laboratory testing revealed hypoalbuminemia, suggesting protein-losing enteropathy. Computed tomography revealed wall thickening of the stomach, small intestine, and colon with contrast enhancement on the lumen side. Antibiotics and immunosuppressive therapy were not effective, and the patient's enteritis did not improve for > 4 mo. Because her condition became seriously exhausted, corticosteroids were tapered and supportive therapies including intravenous hyperalimentation, replenishment of albumin and gamma globulin, plasma exchange, and infection control were continued. These supportive therapies improved her condition, and her enteritis gradually regressed. She was finally discharged 7 mo later. CONCLUSION: Immediate discontinuation of CPA and intensive supportive therapy are crucial for the survival of patients with CPA-associated severe enteritis.

    OBJECTIVES: To collect clinical information and NOD2 mutation data on patients with Blau syndrome and to evaluate their prognosis. METHODS: Fifty patients with NOD2 mutations were analysed. The activity of each NOD2 mutant was evaluated in HEK293 cells by reporter assay. Clinical information was collected from medical records through the attending physicians. RESULTS: The study population comprised 26 males and 24 females aged 0-61 years. Thirty-two cases were sporadic, and 18 were familial from 9 unrelated families. Fifteen different mutations in NOD2 were identified, including 2 novel mutations (p.W490S and D512V); all showed spontaneous nuclear factor kappa B activation, and the most common mutation was p.R334W. Twenty-six patients had fever at relatively early timepoints in the disease course. Forty-three of 47 patients had a skin rash. The onset of disease in 9 patients was recognised after BCG vaccination. Forty-five of 49 patients had joint lesions. Thirty-eight of 50 patients had ocular symptoms, 7 of which resulted in blindness. After the diagnosis of Blau syndrome, 26 patients were treated with biologics; all were antitumour necrosis factor agents. Only 3 patients were treated with biologics alone; the others received a biologic in combination with methotrexate and/or prednisolone. None of the patients who became blind received biologic treatment. CONCLUSIONS: In patients with Blau syndrome, severe joint contractures and blindness may occur if diagnosis and appropriate treatment are delayed. Early treatment with a biologic agent may improve the prognosis.

    Staphylococcus aureus uses IsdG and IsdI to convert heme into a mixture of staphylobilin isomers, 15-oxo-β-bilirubin and 5-oxo-δ-bilirubin, formaldehyde, and iron. The highly ruffled heme found in the heme-IsdI and IsdG complexes has been proposed to be responsible for the unique heme degradation products. We employed resonance Raman (RR) and electron paramagnetic resonance (EPR) spectroscopies to examine the coordination and electronic structures of heme bound to IsdG and IsdI. Heme complexed to IsdG and IsdI is coordinated by a neutral histidine. The trans ligand is hydroxide in the ferric alkaline form of both proteins. In the ferric neutral form at pH 6.0, heme is six-coordinated with water as the sixth ligand for IsdG and is in the mixture of the five-coordinated and six-coordinated species for IsdI. In the ferrous CO-bound form, CO is strongly hydrogen bonded with a distal residue. The marker lines, ν2 and ν3, appear at frequencies that are distinct from other proteins having planar hemes. The EPR spectra for the ferric hydroxide and cyanide states might be explained by assuming the thermal mixing of the d-electron configurations, (dxy)2(dxz,dyz)3 and (dxz,dyz)4(dxy)1. The fraction for the latter becomes larger for the ferric cyanide form. In the ferric neutral state at pH 6.0, the quantum mechanical mixing of the high and intermediate spin configurations might explain the peculiar frequencies of ν2 and ν3 in the RR spectra. The heme ruffling imposed by IsdG and IsdI gives rise to unique electronic structures of heme, which are expected to modulate the first and subsequent steps of the heme oxygenation.

    BACKGROUND: Glucocorticoid-induced osteoporosis and vertebral fracture are common complications in patients on glucocorticoid treatment for rheumatological diseases. The present study aimed to identify the risk factors of vertebral fracture in Japanese female patients with glucocorticoid-induced osteoporosis. METHODS: This study included 225 Japanese women with glucocorticoid-induced osteoporosis and 72 patients with postmenopausal osteoporosis. All participants were treated with bisphosphonate or denosumab for osteoporosis with active form of vitamin D for at least 3 years. The differences of clinical parameters, including age, disease duration, body mass index (BMI), bone mineral density (BMD), and the dose and treatment duration of glucocorticoid were assessed between patients with and without vertebral fracture. Multivariate logistic regression analysis was also performed to evaluate the association of vertebral fracture with clinical parameters. RESULTS: The significant differences related to age, BMD of the hip, disease duration, glucocorticoid treatment duration between patients with and without vertebral fractures were demonstrated. The present study indicated that disease duration, BMI, and the total hip BMD were independent risk factors for vertebral fractures in patients with glucocorticoid-induced osteoporosis. CONCLUSIONS: Prolonged disease duration, low BMI, and low total hip BMD could be risk factors of vertebral fracture in patients on glucocorticoid treatment for rheumatological diseases.

    We report a case of polycythaemia vera (PV) associated with IgA vasculitis. A 45-year-old man was admitted for evaluation of abdominal pain and palpable purpura. IgA vasculitis was diagnosed, and oral prednisolone therapy (30 mg/day) was initiated. On day 6, the patient developed left hemiparesis, and magnetic resonance imaging revealed acute cerebral infarction. Bone marrow biopsy results and the identification of a Janus kinase 2 (JAK2) mutation led to the diagnosis of PV. Despite steroid therapy, urine protein levels increased to 15 g/g・Cre. Renal biopsy demonstrated mild mesangial proliferation with IgA deposits, but immunosuppressive therapy was partially effective. This case suggests that PV can be a complication of IgA vasculitis and that preventive measures for thrombosis should be taken in such cases.

    We herein report a case of migratory aortitis after the administration of granulocyte-colony-stimulating factor (G-CSF) to a 65-year-old woman with a history of pancreatic cancer. She was being administered pegfilgrastim and developed aortitis around the aortic arch. Although it resolved within two weeks, she again developed aortitis around the descending aorta, presenting as migratory aortitis, after pegfilgrastim was resumed. We further experienced three additional cases of G-CSF-induced aortitis that also showed spontaneous resolution, suggesting no or short-term use of immunosuppression. Aortitis due to G-CSF can present as migratory aortitis, since aortitis can quickly resolve and inflammation can recur at a different location.

    Polymyalgia rheumatica (PMR) is an inflammatory disorder in the elderly and is characterized by pain in the shoulders and lower back. Previous studies from western countries have shown that relapse is frequent; however, there are only a few reports on the relapse rate in Japan. Here we examined the relapse rate, and sought to identify factors that predict recurrence in patients with PMR. Of 110 patients who fulfilled the Bird's criteria for PMR between May 2011 and June 2019, 21 patients were excluded, and the remaining 89 patients were followed up until July 2019. Relapse was defined when clinical symptoms were exacerbated and serum C-reactive protein level increased. The relapse-free survival curves were plotted using the Kaplan-Meier method, and log-rank test was used for statistical analysis. The mean age of the 89 patients (50 males and 39 females) was 71.8 years. The mean dose of initial prednisolone (PSL) was 11.8 mg/day. The 1-, 3-, and 5-year relapse-free survival rates were 81.6%, 58.0%, and 52.3% (N = 59, 21, and 7), respectively. In patients who experienced recurrence, the 1- and 3-year second relapse-free survival rates were 58.3% and 27.3% (N = 18 and 3), respectively. Immunosuppressants, such as methotrexate and tacrolimus, were added to PSL in 19 of 30 patients who experienced relapse at the discretion of the attending physicians; however, none of the immunosuppressants worked for preventing second relapses and had steroid-sparing effects. These results indicate that effective immunosuppressants are required to suppress relapse in the treatment of PMR.

    Recently, biological disease-modifying antirheumatic drugs (bDMARDs) have revolutionized the treatment of rheumatoid arthritis (RA) and provided patients with a higher chance of achieving clinical remission. Among them, abatacept (ABT), which selectively inhibits T cell activation through blocking costimulation signal, has been reported efficacious in controlling disease activity. Previous studies have shown that ABT has a high retention rate of up to three years with tolerable adverse events; however, it remains unclear whether this is maintained in the longer term. Here we conducted a retrospective five-year follow-up study to explore prognostic factors concerning better retention. In total, 98 patients who were treated with ABT from May 2011 to July 2019 in Osaki Citizen Hospital were enrolled, including 73 female patients (74.5%). The Kaplan-Meier method was used to estimate the retention rate of ABT. The mean age of ABT initiation was 72.1 years. Concomitant methotrexate was prescribed for 39 patients, and ABT was used as the first-line bDMARD for 65 patients. Rheumatoid factor (RF) was positive in 79 patients. One-, three-, and five-year retention rates of ABT were 83.3%, 66.2%, and 62.7%, respectively. Approximately two-thirds of discontinuation resulted from an inadequate response. Multivariate logistic regression analysis revealed that positive RF was associated with better drug retention. Receiver operating characteristics analysis showed that patients with high RF (≥ 45 IU/mL) had better retention rate of ABT. In conclusion, ABT shows high retention rate among patients with positive RF. The present study may provide better insights when selecting bDMARDs.

    Systemic sclerosis (SSc) is characterized by skin sclerosis and multiple organ damages which may cause mortality and is usually accompanied with several specific autoantibodies, each of which is associated with characteristic complications. Among them, anticentriole antibody is recently reported to be highly associated with SSc-associated pulmonary arterial hypertension (SSc-PAH). In general, several vasodilators are used as therapeutic drugs for SSc-PAH, whereas immunosuppressive therapies are not. Here, we report the case of a 62-year-old female with anticentriole antibody-positive SSc-PAH treated with immunosuppressants and vasodilators. She presented with two-year exertional dyspnea and was diagnosed with PAH and SSc owing to the centriole staining pattern and other symptoms without digital sclerosis. Oral vasodilators were initially administered but were not sufficiently effective on dyspnea. Immunosuppressants such as prednisolone and cyclophosphamide were started. Both of them improved mean pulmonary arterial pressure and 6-minute walk distance, and the anticentriole antibody also disappeared. In this case, SSc-PAH with anticentriole antibody was properly diagnosed and immunosuppressants and vasodilators improved the hemodynamics of PAH with anticentriole antibody and stably maintained it and, in addition, reduced the titer of anticentriole antibody. This indicates that anticentriole antibody might represent a good responsive group to therapies among subgroups of patients with SSc-PAH.

    Methotrexate (MTX)-associated classical Hodgkin lymphoma (CHL) is unlikely to regress following discontinuation of MTX, and its treatment usually requires chemotherapy. Standard chemotherapy for CHL is the ABVD regimen, which contains pneumotoxic bleomycin. This can be problematic in MTX-CHL patients suffering from an autoimmune disease (AID), such as rheumatoid arthritis (RA), as they frequently have pulmonary complications. However, brentuximab vedotin (BV)-containing chemotherapy without bleomycin (A + AVD regimen) was recently reported to show favorable efficacy for CHL, and could therefore be beneficial in MTX-CHL. We treated three cases of MTX-CHL using the A + AVD regimen. All were female and had received MTX for more than 15 years. Underlying AIDs in these patients were RA in two patients, and overlap syndrome with systemic lupus erythematosus and dermatomyositis in one patient. The A + AVD regimen resulted in a complete response in all patients. Peripheral neuropathy developed in two patients, necessitating reduction of the BV dose. All three patients experienced hematological toxicity necessitating dose reduction; however, no severe adverse effects, including infection or pulmonary complication, were documented. RA was well-controlled without additional immunosuppressants. The A + AVD regimen is a promising chemotherapy for MTX-CHL with favorable efficacy and tolerable toxicity profiles.

    Systemic lupus erythematosus (SLE) is an autoimmune disease. It is characterized by the production of various pathogenic autoantibodies and is suggested to be triggered by increased type I interferon (IFN) signature. Previous studies have identified increased plasmablasts in the peripheral blood of SLE patients. The biological characteristics of SLE plasmablasts remain unknown, and few treatments that target SLE plasmablasts have been applied despite the unique cellular properties of plasmablasts compared with other B cell subsets and plasma cells. We conducted microarray analysis of naïve and memory B cells and plasmablasts (CD38+CD43+ B cells) that were freshly isolated from healthy controls and active SLE (n = 4, each) to clarify the unique biological properties of SLE plasmablasts. The results revealed that all B cell subsets of SLE expressed more type I IFN-stimulated genes. In addition, SLE plasmablasts upregulated the expression of cell cycle-related genes associated with higher FOXM1 and FOXM1-regulated gene expression levels than that in healthy controls. This suggests that a causative relationship exists between type I IFN priming and enhanced proliferative capacity through FOXM1. The effects of pretreatment of IFNα on B cell activation and FOXM1 inhibitor FDI-6 on B cell proliferation and survival were investigated. Pretreatment with IFNα promoted B cell activation after stimulation with anti-IgG/IgM antibody. Flow cytometry revealed that pretreatment with IFNα preferentially enhanced the Atk and p38 pathways after triggering B cell receptors. FDI-6 inhibited cell division and induced apoptosis in activated B cells. These effects were pronounced in activated B cells pretreated with interferon α. This study can provide better understanding of the pathogenic mechanism of interferon-stimulated genes on SLE B cells and an insight into the development of novel therapeutic strategies.

    A 30-year-old man with severe hypoalbuminemia (serum albumin: 0.9 g/dL) was admitted with severe bilateral leg edema and unilateral pleural effusion. Serum anti-SS-A and SS-B antibody levels were abnormally elevated, and his symptoms fulfilled the diagnostic criteria for Sjögren's syndrome. Technetium-99m albumin scintigraphy revealed protein leakage from a large area of the small intestine. Immunohistochemistry revealed perivascular deposition of C1q, C3d, and immunoglobulin G in the duodenal mucosa. The patient was diagnosed with protein-losing gastroenteropathy associated with Sjögren's syndrome. Within 2 months of treatment with oral prednisolone and mycophenolate mofetil, the clinical symptoms of hypoalbuminemia and Sjögren's syndrome disappeared completely.

    Takayasu arteritis (TAK) is a subtype of the large-vessel vasculitis, affecting the aorta and its major branches. Although T cell-mediated autoimmunity is mainly involved in vascular inflammation, in recent years, accumulating evidence suggests the important role of B cells in the pathogenesis and effectiveness of B-cell-targeted therapy with rituximab (RTX), a chimeric anti-CD20 monoclonal antibody in refractory TAK. Herein, we report for the first time a case involving a 34-year-old man with TAK who was refractory to four different biologic agents, such as one selective T-cell co-stimulation modulator (abatacept), one anti-interleukin-6 receptor monoclonal antibody (tocilizumab), and two tumor necrosis factor-α inhibitors (infliximab and etanercept), but eventually achieved remission with RTX. He received a total of six courses of RTX, and doses of prednisolone and methotrexate were tapered without relapse. The current case provided further evidence to the potential role of RTX therapy in patients with refractory TAK, and its efficacy needs to be validated in a controlled trial.

    OBJECTIVE: Although prednisolone (PSL) and immunosuppressants are key drugs for Takayasu arteritis (TA) treatment, there is limited evidence on the optimal PSL dose. The aim of this study was to investigate the correlation between the initial PSL dose and relapse in TA. METHODS: We enrolled 105 patients with TA who satisfied the criteria of the Japanese Circulation Society and American College of Rheumatology from 1990 to 2015. The clinical characteristics and outcomes of patients with TA were retrospectively evaluated. The relapse-free period was assessed according to the difference in initial treatments. RESULTS: Relapse was observed in 57 (59.4%) of 96 patients treated with immunosuppressive therapy at diagnosis during a median followup of 56 months. Male sex and younger age of onset were significantly associated with relapse. Although ≤ 30 mg/day PSL monotherapy was preferably prescribed for patients with lower inflammatory markers, compared with > 30 mg/day (87.2% vs 52.6%), a significantly higher relapse rate was observed in the ≤ 30 mg/day group (HR 1.78; p = 0.047). Further, the relapse-free period was longer in patients treated with ≥ 50 mg/day PSL compared with those treated with ≤ 40 mg/day PSL. Combination therapy improved the relapse-free period compared with PSL monotherapy in the short term. The initial PSL dose was not associated with adverse events. CONCLUSION: A higher dose of PSL was associated with a significant decrease in the relapse rate. The effect of combination therapy on relapse needs to be further investigated. Lower-dose PSL monotherapy is an undesirable strategy for remission induction in TA, despite low disease activity.

    OBJECTIVE:Within the spectrum of polyarteritis nodosa (PAN), cutaneous PAN (cPAN) is further classified into mild cPAN and severe cPAN which presents with ulcers, necrosis, or neuritis. As distinguishing between severe cPAN and systemic PAN can be difficult, this study evaluated the clinical characteristics of patients with necrotizing arteritis of medium-sized arteries. METHODS:Forty-one patients diagnosed with necrotizing arteritis of medium-sized arteries between 2008 and 2017 at our institution were enrolled in this study. Clinical background, laboratory findings, treatments, and rates of relapse and death were evaluated. RESULTS:Thirty-six patients were classified as having cPAN (mild, 15; ulcer, nine; neuritis, eight; both, four), and five cases manifested systemic vasculitis. Clinical characteristics of mild cPAN included female predominance (84.6%) and younger age (median 31 years); those of systemic PAN included older age (median 71 years) and higher levels of inflammatory markers. Severe cPAN manifested with intermediate phenotypes. The median doses of prednisolone used to treat mild cPAN, severe cPAN, and systemic PAN were 20.0, 40.0, and 40.0 mg/day, respectively. Immunosuppressants were used in 20.0% of mild cPAN, 90.5% of severe cPAN, and 80.0% of systemic PAN patients. Although the mortality rates were indistinguishable, the relapse rates of severe cPAN (ulcer type) were significantly higher than those of other types (88.9%). CONCLUSION:The clinical characteristics of mild cPAN, severe cPAN (ulcer type), severe cPAN (neuritis type), and systemic PAN were distinct from each other. In particular, patients with severe cPAN (ulcer type) had higher relapse rates, indicating the importance of combination therapy.

    A 16-year-old boy, who had been initially examined for bilateral blepharedema and slight eruption, presented with rapidly deteriorating symptoms in associating with headache and consciousness disturbance. He was diagnosed to have primary cutaneous CD8-positive aggressive epidermotropic cytotoxic T-cell lymphoma (PCAE-CTL) by a biopsy of the skin and brain. After whole-brain radiation and some courses of chemotherapy, cord blood transplantation was performed with myeloablative conditioning. After transplantation, the cerebral dysfunction gradually improved. Disease remission was confirmed by the disappearance of any abnormal findings on electroencephalogram and magnetic resonance imaging. PCAE-CTL is reported to be an extremely aggressive disease with a poor prognosis, but the timely performance of cord blood transplantation is considered to be a promising treatment strategy.

    Here, we present a 54-year-old man with proptosis and swelling below the left eyelid. Laboratory findings showed high levels of PR3-ANCA and histological examination of the first biopsy revealed acute inflammation. Together with the findings of MRI, a diagnosis of WG was made. However, the disease progressed rapidly and histological examination of the second biopsy revealed infiltration of neoplastic T lymphocytes with aberrant loss of CD7. A final diagnosis of peripheral T cell lymphoma, not otherwise specified (WHO) was made, and complete remission was achieved by chemotherapy. This is a very rare case of T cell lymphoma with a high titer of PR3-ANCA.<br>

    To clarify the clinicopathological features of Churg-Strauss syndrome (CSS), we examined 12 cases that presented with clinical features described by Churg and Strauss and also fulfilled the cristeria of American college of rheumatology. Patients, 5 male and 7 female, were 51.8 years of mean age. Anti-neutrophil cytoplasmic antibody (ANCA) was positive in 7 cases (58%, MPOANCA in 6, PR3-ANCA in1). All patients had a medical history of bronchial asthma (BA). Various organ involvements such as mononeuritis multiplex (12 cases), skin (9 cases), sinusitis (8 cases), lung and heart (5 cases, respectively), sensory organ (4 cases), central nervous system (2 cases), and gastrointestinal tract and kidney (1case, respectively) were observed. ANCA positive patients had significantly higher prevalence of skin involvement than ANCA negative patients. We also observed a tendency of ANCA negative patients having a higher frequency of lung and heart lesion.<br>    Skin biopsy was performed in6cases.Extravascular infiltration of eosinophils was observed in all of them, but necrotizing vasculitis and extravascular granuloma, which is thought to be characteristic to CSS, was observed in only1case, respectively. Neural biopsy was done in 4 cases. Almost all the cases showed axonal degeneration and decrease of nerve fiber density, but no cases showed necrotizing vasculitis and extravascular granuloma.<br>    In conclusion, various types of organ involvement were observed in12cases with CSS, but typical pathological changes such as necrotizing vasculitis and extravascular granuloma were not common in CSS.

    INTRODUCTION: Patients with lupus enteritis sometimes experience recurrence. In such cases, the addition of cyclophosphamide to the treatment regimen is recommended. However, an appropriate treatment has not been established in cases where cyclophosphamide failed to prevent the disease. CASE PRESENTATION: An 18-year-old Japanese woman was admitted for a recurrence of lupus enteritis. One year before admission she was treated for lupus enteritis with high-dose corticosteroid together with intravenous cyclophosphamide pulse therapy. Upon admission, she was administered again with high-dose corticosteroid and her abdominal pain rapidly subsided. Tacrolimus was later used as an immunosuppressive agent and a complete remission has been maintained. CONCLUSION: Tacrolimus can be a useful agent for recurrent lupus enteritis that is resistant to conventional therapy.

    We describe a case of a 61-year-old woman with amyopathic dermatomyositis (ADM), who developed rapidly progressive interstitial pneumonia and died of respiratory failure. An autopsy revealed interstitial pneumonia with diffuse alveolar damage, associated with infiltration of T cells, mostly positive for CD 8. The alveolar lining epithelial cells manifested the remarkable expression of immediate early/early antigen of human cytomegalovirus (HCMV). Moreover, the extract of the lung was transmittable of HCMV infection to cultured human embryo-fibroblasts in vitro. On the other hand, in the semi-quantitative analysis of HCMV genome, using laser-assisted microdissection, followed by PCR method, the genomic DNA in the alveolar lining epithelial cells was little detected in this case, although it was remarkable in the case of immunodeficiency with cytomegalovirus pneumonia. This case may be important to know the role of the immune response of host to HCMV infection on the development of rapidly progressive interstitial pneumonia.

    本研究の目的は、末梢血形質芽細胞におけるSLE患者と健常人間での発現変動遺伝子(in vivoマイクロアレイ)とBCRのみの刺激とBCR+TLR9の共刺激間での発現変動遺伝子(in vitroマイクロアレイ)の比較に基づき、共通に上昇している遺伝子抽出し、それらの分子を特異的に標的する方法を開発(薬剤の探索)し、最終的にSLE形質細胞を特異的に標的とする治療法の開発につなげる。 今年度の研究では、通常のB細胞刺激である抗BCR抗体+CD40Lと病的B細胞(自己反応性B細胞)刺激を想定した抗BCR抗体+CpG(TLR9のリガンド)あるいは抗BCR抗体+R848 (TLR7/8のリガンド)の遺伝子発現をRT-PCRで定量し、in vivoマイクロアレイと比較した。当初は抗BCR抗体+CpG+IFNαによる刺激がもっともin vivoでのSLE形質細胞に特異的な遺伝子変化を反映すると考えていたが、CDC7、MEF2BなどのSLE形質細胞において特異的に上昇している遺伝子は抗BCR抗体+R848+IFNαによる刺激において特異的に上昇していた。また、CDC7阻害薬TAK-931が抗BCR抗体+R848+IFNαにより誘導される細胞分裂を著明に抑制した。来年度以降、抗BCR抗体+R848による刺激をSLEにおける病的B細胞が受ける刺激のprototypeとして特異的な遺伝子発現、分化、機能解析を行う。

    Gene expression profiling analysis of human dermal microvascular endothelial cells (HDMEC) with microarray revealed that the transcriptional factor FOSB was more than 10-folds increased after irradiation of shock wave. Shock wave treatment induced the gene expression of FOSB and CXCL2 in rat skin. Up-regulator analysis showed that the gene set induced by shock wave treatment highly correlated with PMA-induced genes. The aberrant expression of FOSB in HDMEC revealed that both of VEGF and CXCL2 were increased co-cultured with PMA, whereas none of these genes were changed without PMA.
