Abstract
We report a case involving a 68-year-old woman with rheumatoid arthritis (RA) with acute exacerbated interstitial lung disease (ILD) during certolizumab pegol maintenance therapy. She recovered quickly with steroid pulse therapy and was discharged without deterioration of basal pulmonary function. Immunoblot analysis demonstrated the circulating cleaved interleukin-1β at the phase of acute exacerbation of RA-associated ILD (RA-ILD) in this patient. The findings from this case suggested that the Nod-like receptor pyrin domain-containing protein 3 inflammasome is implicated in acute RA-ILD exacerbation.

Abstract
Few data are available regarding vertebral fracture risk in patients treated with corticosteroids including patients with interstitial lung disease (ILD). The aim of the present study was to identify risk factors for symptomatic vertebral fracture analyzed in patients with newly diagnosed autoimmune diseases.This was an observational cohort study conducted in the National Hospital Organization-EBM study group from 2006 to 2008. The study subjects were autoimmune disease patients who were newly treated with glucocorticoids (GCs). The primary endpoint was the first occurrence of vertebral fracture diagnosed by x-rays. Cox proportional-hazards regression was used to determine independent risk factors for vertebral fracture with covariates including sex, age, comorbidity, laboratory data, use of immunosuppressants, and dose of GCs. Survival was analyzed according to the Kaplan-Meier method and assessed by the log-rank test.Among 604 patients of mean age 59.5 years and mean GC dose 50.4 mg/d (first 1 months), 19 patient (3.1%) had at least 1 symptomatic vertebral fracture during 1.9 years of follow-up period. Cox regression model demonstrated that the relative risk for symptomatic vertebral fracture was independently higher in patient with ILD (hazard ratio [HR] = 2.86, 95% confidence interval [CI] = 1.10-7.42, P = 0.031) and in every 10-year increment of the age of disease onset (HR = 1.57, 95% CI = 1.09-2.26, P = 0.015). Kaplan-Meier analyses demonstrated that the incidence of vertebral fractures in patients with ILD was significantly higher in comparison with those without ILD.Our results indicate a higher risk of vertebral facture in patients with ILD and elderly patients during the initial GC treatment against autoimmune diseases. There is a need for further, even longer-term, prospective studies subjected patients with autoimmune disease, including ILD, under GC treatment.

Abstract
Introduction In rheumatoid arthritis (RA) patients receiving immunosuppressive treatments, vaccination against Streptococcus pneumoniae is recommended. The objective of the study was to evaluate the effects of tacrolimus (TAC) on immune response following administration of a 23-valent pneumococcal polysaccharide vaccine (PPSV23) in patients with established RA. Methods Patients with RA (n = 133) were vaccinated with PPSV23. Patients were classified into TAC (n = 29), methotrexate (MTX) (n = 55), control (n = 35), and TAC/MTX (n = 14) treatment groups. We measured the concentrations of pneumococcal serotypes 6B and 23F by using an enzyme-linked immunosorbent assay and determined antibody functionality by using a multiplexed opsonophagocytic killing assay, reported as the opsonization index (OI), before and 4 to 6 weeks after vaccination. A positive antibody response was defined as at least a twofold increase in the IgG concentration or as at least a 10-fold increase in the OI. Results IgG concentrations and OIs were significantly increased in all treatment groups after PPSV23 vaccination. The TAC treatment group appears to respond in a manner similar to that of the RA control group in terms of 6B and 23F serotype concentration and function. In contrast, the MTX group had the lowest immune response. Patients who received a combination of TAC and MTX (TAC/MTX) also had a diminished immune response compared with those who received TAC alone. Conclusions TAC monotherapy does not appear to impair PPSV23 immunogenicity in patients with RA, whereas antibody production and function may be reduced when TAC is used with MTX. Thus, PPSV23 administration during ongoing TAC treatment should be encouraged for infection-prone TAC-treated patients with rheumatic diseases.

Abstract
A 63-year-old Japanese woman with a 30-year history of systemic lupus erythematosus developed macrohematuria and massive proteinuria after seroconversion of myeloperoxidase anti-neutrophil cytoplasmic antibodies (MPO-ANCA). A renal biopsy indicated focal proliferative lupus nephritis (class III A/C) with a fibrous crescent formation. Methylprednisolone pulse therapy (500 mg, 3 successive days) was administered because of progressive proteinuria. Steroid therapy did not suppress the progressive proteinuria; therefore, tacrolimus was added as an alternative immunosuppressive therapy, resulting in the improvement of proteinuria and renal impairment. This case report suggests that MPO-ANCA might play a pathogenic role in the exacerbation of immune-complex-type lupus nephritis.

Abstract
A 50-year-old woman was referred to our hospital for shoulder joint stiffness. She had a history of polyclonal hypergammaglobulinemia and an elevated C-reactive protein level. Her laboratory data revealed an elevated serum immunoglobulin G4 (IgG4) level, hypergammaglobulinemia, and rheumatoid factor positivity in the absence of anticyclic citrullinated peptide antibody. [18F]-Fluorodeoxyglucose positron emission tomography showed significant [18F]-fluorodeoxyglucose uptake in multiple lymph nodes (axillary, hilar, para-aortic, and inguinal). Biopsy of the inguinal lymph node showed expansion of the interfollicular areas by heavily infiltrating plasma cells, consistent with multicentric Castleman disease (MCD). Immunohistochemical analysis revealed a 37.3% IgG4-positive:IgG-positive plasma cell ratio, indicating overlapping IgG4-related disease. However, serological cytokine analysis revealed elevated levels of interleukin-6 (9.3 pg/ml) and vascular endothelial growth factor (VEGF) (1210 pg/ml), which are compatible with MCD. Corticosteroid treatment resolved the serological and imaging abnormalities. IgG4-related disease can mimic MCD, and it is crucial to distinguish between these two diseases. Serum interleukin-6 and VEGF levels may help to discriminate MCD from IgG4-related disease.

Abstract
Interstitial lung disease (ILD) has a heterogeneous clinical presentation and establishing prognosis for these patients is challenging. We investigated the clinical characteristics and outcome of patients with idiopathic interstitial pneumonias (IIPs) and patients with connective tissue disease-associated interstitial lung disease (CTD-ILD). We conducted a multicenter prospective study on 104 patients diagnosed with IIPs and 29 patients diagnosed with CTD-ILD, which were newly diagnosed and treated with corticosteroids initially. We compared the clinical characteristics, high-resolution computed tomography (HRCT) imaging date, and outcomes. Cox proportional hazard regression analysis was used to identify variables with increased risk of death. Survival was analyzed according to the Kaplan-Meier method and was assessed with the log-rank test. Of 133 patients with IIPs (n = 104) or CTD-ILD (n = 29), 44 patients died during the follow-up period (mean: 1.6 ± 0.78 years). Patients with IIPs seemed to be associated with worse survival compared with those with CTD-ILD; however, this difference was not significant (log-rank test, P = 0.084). Significant predictors for mortality in patients with IIPs at baseline were lower for performance status and definite usual interstitial pattern (UIP) on HRCT. Patients with UIP experienced worse survival than those with non-UIP. A definite UIP on HRCT and lower baseline performance status have important prognostic implications in patients with IIPs.

Abstract
OBJECTIVES The risk factors of adverse events during a number of currently used treatments for rheumatoid arthritis (RA) in elderly patients were examined. METHODS A retrospective observational study was conducted for 300 elderly RA patients registered in December 2009 at Sasebo Chuo Hospital, Japan, and the adverse events during the treatments for RA were assessed. RESULTS The average age of the patients was 74.3 ± 5.8 years. The Steinbrocker stage was IV in almost one-half of the patients. Methotrexate (MTX) was used in 54.0% of patients and biologics in 23.0% of patients. Adverse events occurred in 103 patients (34.3%). The most common adverse events were infections (46.6%), including pneumonia (21.4%). Multiple logistic analyses revealed that the factors significantly related to infection were advanced Steinbrocker stage and the existence of respiratory diseases, and that of pneumonia was the existence of diabetes mellitus (DM). CONCLUSIONS The elderly RA patients with advanced stage, respiratory diseases or DM should be monitored for infections, including pneumonia, carefully during treatment.

Abstract
An 82-year-old woman was previously diagnosed with cholecystitis and treated with antibiotics at another hospital. Because her fever and inflammation persisted, therapeutic cholecystectomy was performed. Histopathology of the gallbladder revealed periarterial vasculitis. After transfer to our hospital, an elevated titer of myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) was observed (47 U/mL). The patient's renal dysfunction had previously been thought to be sequelae of her cholecystectomy. We diagnosed microscopic polyangiitis (MPA) and began treatment with 40 mg orally of prednisolone daily. The titer of MPO-ANCA decreased with the treatment, but fever recurred with prednisolone taper. We, therefore, added 50 mg orally of mizoribine (MZR) daily as an immunosuppressant and increased the MZR to 100 mg daily while monitoring its blood peak concentration. The peak level of MZR was 1.58 μg/mL at 6 h after administration. After adding MZR, we successfully tapered the orally dosed prednisolone without recurrent fever or complications. We describe this case of MPA in an elderly patient manifesting predominantly with cholecystitis and successfully treated with orally dosed prednisolone and MZR.

Abstract
Recently, it was reported that remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome could be complicated with solid tumors. In a retrospective, multicenter study between October, 2003 and September, 2010, we investigated the characteristics of patients with paraneoplastic RS3PE syndrome who fulfilled following criteria: (1) bilateral pitting edema of hands or feet or both, (2) sudden onset of polyarthritis, and (3) age >50 years, (4) seronegativity for rheumatoid factor (RF). A total of 33 cases fulfilled the above criteria. Eight patients (seven men and one woman) developed cancer within 2 years of RS3PE syndrome onset. There was no significant difference between the neoplastic and nonneoplastic groups in the proportions of patients with fever, symmetrical polyarthritis, pitting edema, and good response to corticosteroids. Serum matrix metalloproteinase 3 (MMP-3) level (median 437.3 ng/ml) in the paraneoplastic RS3PE patients was significantly higher than that in patients without neoplasia (median 114.7 ng/ml) (p < 0.05). We found that high serum MMP-3 is characteristic of patients with paraneoplastic RS3PE syndrome.

Abstract
OBJECTIVE To determine the significance of bone edema, detected by magnetic resonance imaging (MRI), in early-stage rheumatoid arthritis (RA). METHODS We simultaneously examined serologic variables, MRI of wrist sites and finger joints of both hands, clinical disease activity score (DAS), and HLA-DR typing at entry in 80 patients with early-stage RA. RESULTS The number of bones scored as positive for bone edema correlated with the number of sites scored as positive for MRI synovitis and MRI bone erosion, rate of enhancement (E-rate), and serum C-reactive protein (CRP), matrix metalloproteinase 3 (MMP-3), and interleukin 6 (IL-6). Findings for MRI synovitis and MRI bone erosion, E-rate, CRP, MMP-3, IL-6, seropositivity, and titer of anti-cyclic citrullinated peptide antibody (anti-CCP antibody), DAS28-CRP and HLA-DRB1*0405 allele carriership, were significantly higher in the positive versus the negative bone edema group. CONCLUSION Bone edema based on our scoring system may reflect severe disease status in patients with early-stage RA. However, its clinical value at entry in prognostication of RA should be examined through prospective clinical followup studies.

Abstract
OBJECTIVE We investigated expression of toll-like receptor (TLR) in labial salivary glands of patients with Sjögren's syndrome (SS) and functional TLR expression in the cultured salivary gland cell line. METHODS Expression of TLR2, TLR3, TLR4, and myeloid differentiation factor 88 (MyD88) in labial salivary glands was examined by immunohistochemistry. Human salivary gland (HSG) cell-line cells were cultured with TLR ligands [peptidoglycan, poly (I:C) and lipopolysaccharide], and CD54 expression and interleukin 6 (IL-6) production was studied. Phosphorylation of extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), p38, and Akt was examined by Western blotting. Activation of nuclear factor-kappaB (NF-kappaB) p65 in HSG cells was studied by NF-kappaB p65 nuclear translocation by microscopic immunofluorescence or chemiluminescent electrophoretic mobility shift assay and detection of NF-kappaB p65 phosphorylation. RESULTS TLR2, TLR3, TLR4, and MyD88 were more strongly expressed in the labial salivary glands of SS patients (n =12) than in control subjects (n = 4), and were found in salivary-infiltrating mononuclear cells as well as acinar cells and ductal epithelial cells. In cultured HSG cells, a similar expression pattern was observed, and TLR ligands stimulated CD54 expression and IL-6 production. TLR ligands induced phosphorylation of ERK, JNK, and p38 in HSG cells, but not Akt phosphorylation or activation of NF-kappaB p65. CONCLUSION Although the putative ligands remain to be determined, our study indicated the activation of the TLR-mediated immune response in SS, and suggested that the TLR effect is mediated through the mitogen-activated protein kinase pathway.

Abstract
The most common renal manifestation of Sjögren's syndrome is tubulointerstitial nephritis, and glomerular disease is rare (3). A 62-year-old woman with primary Sjögren's syndrome developed nephrotic syndrome. Kidney biopsy was consistent with membraneous glomerulonephritis. Steroid pulse therapy was not effective. Three months later she was diagnosed with non-Hodgkin's lymphoma of the tongue, and she was given CHOP therapy and radiation. Both the lymphoma and membraneous glomerulonephritis were resolved.

Abstract
A 35-year-old woman with primary Sjögren's syndrome (pSS) developed fever and chest pain during pregnancy. When the dose of prednisolone was reduced, she experienced chest pain with elevated CRP and D-dimer, resulting in admission to our hospital with marked cardiomegaly and pleural effusion. Because there was no evidence of other autoimmune disorders or infection, oral prednisolone was increased to 30 mg daily with heparin, and hypercoagulopathy was carefully monitored. The patient's condition improved rapidly, and she delivered a healthy baby. This is the first case to support the beneficial effect of prednisolone in pericarditis with pSS, and illustrates its safety during pregnancy.
