ABSTRACT

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

ABSTRACT

Streptococcus pyogenes is a rare pathogen that causes endogenous endophthalmitis (EE). A healthy 58-year-old woman was diagnosed with EE secondary to septic arthritis caused by S. pyogenes. She underwent enucleation after hospitalization for 14 days with appropriate antibiotic cover. A literature search for outcomes of this condition revealed reports on only 10 eyes among 8 cases identified: 8 eyes (80%) developed poor visual outcome and 5 eyes (50%) underwent enucleation. There were no cases with immunocompromise. Our case report and literature review suggest the importance of awareness of the occurrence of S. pyogenes infection in immunocompetent hosts, and thus early diagnosis and aggressive treatment may be required to improve visual outcome.

ABSTRACT

Background: Pentraxin 3 (PTX3) has an important role in inflammation, immunity, and atherosclerosis. Rheumatoid arthritis (RA) is a chronic inflammatory disease featuring both joint damage and atherosclerosis. We investigated whether the plasma PTX3 level was associated with progression of joint destruction and subclinical atherosclerosis in RA patients.Methods: Plasma PTX3 levels were measured in 72 women with RA and 80 female control subjects. In RA patients, we also evaluated clinical characteristics, medications, and at one and three years, joint damage and atherosclerosis. Then we investigated whether PTX3 was associated with progression of joint destruction or an increase of carotid intima-media thickness (IMT).Results: Plasma PTX3 levels were significantly higher in the RA patients than in healthy controls (4.05 ± 2.91 ng/mL vs. 1.61 ± 1.05 ng/mL, p < .001). By multivariate linear regression analysis, the plasma pentraxin 3 level was independently associated with radiographic progression of joint damage for 3 years in the RA patients after adjustment for age, disease duration, body mass index, rheumatoid factor, MMP-3, Disease Activity Score 28-ESR, postmenopausal status, current use of corticosteroids and biologic use. On the other hands, pentraxin 3 was not associated with an increase of carotid intima-media thickness in RA patients.Conclusion: Female RA patients had elevated plasma PTX3 levels compared with control female subjects. PTX3 was independently associated with radiographic progression of joint damage in the RA patients, but not with carotid atherosclerosis.

ABSTRACT

AIM: Superb microvascular imaging (SMI), a novel ultrasonography, is based on the sensitivity of Doppler technology. This study evaluated power Doppler (PD) ultrasound signals in patients with rheumatic disease using SMI and conventional PD imaging (cPDI) and compared the correlations of these signals to clinical assessments. METHODS: Thirty-nine patients with rheumatic disease (27 rheumatoid arthritis [RA] and 12 non-RA) were enrolled. We investigated SMI and cPDI signals in 26 joints using an Aplio 300. Individual scores were summed to calculate total SMI and cPDI scores. RESULTS: Total SMI scores were significantly higher than total cPDI scores in patients with RA, but not in those with the non-RA disease. Total SMI score was associated with serum levels of C-reactive protein (CRP) and matrix metalloproteinase-3; disease activity score 28-CRP and health assessment questionnaire disability index scores, and SMI were more sensitive to detect active synovitis than cPDI in RA patients. Among the joint regions, the wrists and metacarpophalangeal joints were more sensitive to the detection of synovial inflammation using SMI in patients with RA. CONCLUSION: SMI was more sensitive in detecting synovial inflammation than cPDI in patients with RA. SMI could be a potentially useful imaging modality for accurately diagnosing and monitoring the disease activity of RA.

ABSTRACT

Interleukin 17 (IL-17) is a cytokine implicated in the promotion of osteoclastogenesis. Its effect has been believed not to be directly exerted on osteoclast precursors, but rather indirectly carried out via an induction of receptor activator of NF-κB ligand (RANKL), the osteoclast differentiation factor, on osteoclast-supporting cells, which in turn exert an effect on osteoclast precursors. The mechanistic details, however, remain unclear. In this study, we first performed a transcriptome analysis of synoviocytes derived from a patient with rheumatoid arthritis cultured in the presence or absence of IL-17. We discovered that most of the genes significantly induced by IL-17 were chemokines with a chemotactic effect on neutrophils. We confirmed these results by quantitative RT-PCR and ELISA. Unexpectedly, the stimulation with IL-17 alone did not induce the expression of RANKL either at the mRNA or the protein level. The induction of RANKL was observed when IL-17 was added in combination with 1,25-dihydroxyvitamin D3 and prostaglandin E2, well-known inducers of RANKL, although the exact mechanism of this synergistic effect remains unclear. IL-6 and monocyte chemoattractant protein-1 were also significantly induced by IL-17 at both the mRNA and protein levels. Thus, it appears that IL-17 induces the migration of neutrophils and monocytes/macrophages through the activation of synoviocytes, and enhances a positive feedback loop composed of proinflammatory cytokines IL-6 and IL-17.

ABSTRACT

Accumulating evidence indicates that epigenetic aberrations have a role in the pathogenesis of rheumatoid arthritis (RA). However, reports on histone modifications are as yet quite limited in RA. Interleukin (IL)-6 is an inflammatory cytokine which is known to be involved in the pathogenesis of RA. Here we report the role of histone modifications in elevated IL-6 production in RA synovial fibroblasts (SFs). The level of histone H3 acetylation (H3ac) in the IL-6 promoter was significantly higher in RASFs than osteoarthritis (OA) SFs. This suggests that chromatin structure is in an open or loose state in the IL-6 promoter in RASFs. Furthermore, curcumin, a histone acetyltransferase (HAT) inhibitor, significantly reduced the level of H3ac in the IL-6 promoter, as well as IL-6 mRNA expression and IL-6 protein secretion by RASFs. Taken together, it is suggested that hyperacetylation of histone H3 in the IL-6 promoter induces the increase in IL-6 production by RASFs and thereby participates in the pathogenesis of RA.

ABSTRACT

OBJECTIVES: Pentraxin 3 (PTX3) plays an important role in inflammation, immunity, and atherosclerosis. Plasma PTX3 level has drawn attention as a marker that responds to local inflammation. Systemic lupus erythematosus (SLE), a chronic inflammatory disorder which can affect multiple organs, develops atherosclerosis prematurely. We examined the hypotheses that the concentration of plasma PTX3 increases in patients with SLE and that PTX3 is associated with the disease activity and premature atherosclerosis. METHODS: Plasma PTX3 concentrations were measured in 65 patients with SLE and 53 control subjects. The patients were also evaluated with respect to their clinical characteristics, disease activity indices, and corticosteroid therapy. We performed carotid ultrasonography to measure subclinical atherosclerosis in patients with SLE. RESULTS: Plasma PTX3 concentration of the SLE patients was significantly higher than that of the healthy controls (median 3.9 vs. 2.0 ng/mL, p < 0.001). In patients with SLE, PTX3 concentrations were correlated with SLEDAI (p = 0.011), BILAG index (p < 0.001), C-reactive protein (p < 0.001), anemia (p = 0.020), hypoalbuminemia (p = 0.022), and daily dose of prednisolone (p = 0.008) after adjustment for age and sex. PTX3 was not associated with disease duration, anti-ds DNA antibody, CH50, or carotid atherosclerosis. CONCLUSIONS: Patients with SLE have increased concentrations of PTX3 compared with control subjects. PTX3 was significantly associated with disease activity but not with carotid atherosclerosis.

ABSTRACT

Osteoclasts, derived from the monocyte/macrophage line of bone marrow hematopoietic stem cell progenitors, are the sole bone-resorbing cells of the body. Conventional osteoclast differentiation requires macrophage colony-stimulating factor and receptor activator of nuclear factor kappa-B ligand (RANKL) signaling. Rheumatoid arthritis (RA) is the most prevalent systemic autoimmune disease and inflammatory arthritis characterized by bone destruction. Increased levels of proinflammatory cytokines, such as tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6), in the serum and joints, cause excessive bone destruction. We have recently reported that stimulation of human peripheral blood monocytes with TNF-α and IL-6 induces the differentiation of osteoclasts with bone resorption activity. This review presents the functional differences between representative osteoclasts, conventional RANKL-induced osteoclasts, and recently identified proinflammatory cytokine (TNF-α and IL-6)-induced osteoclasts in RA patients. We believe novel pathological osteoclasts associated with RA will be identified, and new therapeutic strategies will be developed to target these osteoclasts and prevent the progression of bone destruction.

ABSTRACT

Vaccines against coronavirus disease 2019 (COVID-19) have been distributed in most countries for the prevention of onset and aggravation of COVID-19. Recently, there have been increasing numbers of reports on new-onset autoimmune and autoinflammatory diseases following COVID-19 vaccination, however, only little information is available on the long-term safety of these vaccines. Here, we experienced three cases of new-onset rheumatic diseases following COVID-19 vaccination, one case each of rheumatoid arthritis (RA), anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and systemic lupus erythematosus (SLE). The symptom onset ranged from one day to a few days following vaccination. The patients of AAV and SLE were treated successfully with glucocorticoid therapy, and the patient of RA died due to COVID-19. In the literature review of new-onset rheumatic diseases following COVID-19 vaccination, which including seven cases of RA, 37 cases of AAV and 18 cases of SLE, the mean time from vaccination to onset was approximately 11 to 12 days. Most cases improved with glucocorticoid, immunosuppressive drugs and biologic agents. Although such adverse effects are rare, and vaccines are useful in prevent onset and severity of infections, continued accumulation of similar cases is important in terms of examining the long-term safety and understanding pathogenic mechanism of rheumatic diseases.

ABSTRACT

OBJECTIVE: Pattern-recognition receptors (PRRs), such as Toll-like receptors (TLRs) and nucleotide-binding oligomerization domain-containing protein 2 (NOD-2), have been shown to contribute to the pathogenesis of rheumatoid arthritis (RA). The aim of this study was to analyze the expression, regulation, and function of the PRR NOD-1 in RA synovial fibroblasts (RASFs), and to examine its interaction with other PRRs. METHODS: Expression of NOD-1 was analyzed by immunohistochemistry in synovial tissue from RA patients, psoriatic arthritis patients, gout patients, and osteoarthritis (OA) patients. RASFs and human monocyte-derived macrophages (HMDMs) were stimulated with L-alanyl-γ-D-glutamyl-meso-diaminopimelic acid, palmitoyl-3-cysteine-serine-lysine-4, poly(I-C), lipopolysaccharide, heat-inactivated bacteria, tumor necrosis factor α (TNFα), or interleukin-1ß (IL-1ß). Expression levels of IL-6, CCL5, matrix metalloproteinases (MMPs), NODs, and TLRs were measured by real-time reverse transcription-polymerase chain reaction and/or enzyme-linked immunosorbent assay. NOD-1 and NOD-2 were silenced with target-specific small interfering RNA. Phosphorylation of IL-1 receptor-associated kinase 1 (IRAK-1) was measured by Western blotting. RESULTS: Expression of NOD-1 protein was significantly increased in RA synovium compared to OA synovium. The basal expression of NOD-1 was similar in RASFs, OASFs, healthy control peripheral blood mononuclear cells, and healthy control HMDMs. Stimulation of RASFs with TLR-3 up-regulated the expression of NOD-1. Expression of IL-6, CCL5, MMPs, TLR-2, and NOD-2 was significantly up-regulated in RASFs by stimulation with the NOD-1 ligand. A synergistic effect on IL-6 production was observed in cells stimulated with NOD-1 and TLR-2 ligands or NOD-1 and TLR-4 ligands. Silencing of NOD-1, but not NOD-2, decreased the levels of IL-6 in RASFs after stimulation with TLR-2 and IL-1ß, and blocked the phosphorylation of IRAK-1. CONCLUSION: NOD-1 is strongly expressed in different cell types in the synovial tissue of patients with RA. These results indicate that NOD-1, either alone or interacting with other inflammatory mediators, can play an important role in the chronic and destructive inflammation of the joints in RA.

ABSTRACT

OBJECTIVE: Osteoprotegerin (OPG), a regulator of bone resorption, is involved in the pathogenesis of rheumatoid arthritis (RA) and atherosclerosis. OPG is elevated in patients with coronary artery disease, and high OPG levels are associated with cardiac disease severity and mortality in the general population. The purpose of this study was to investigate the relationship of serum OPG levels, traditional coronary risk factors, and RA-related factors to carotid atherosclerosis in RA patients. METHODS: Ninety-one RA patients were studied (85 % women, age 60 ± 10 years). Serum OPG levels were measured by an enzyme-linked immunosorbent assay. The prevalence of carotid plaque was assessed by ultrasonographic imaging in all patients. The relationship between various clinical characteristics, OPG, and carotid plaque was examined. RESULTS: Serum OPG levels were significantly higher in patients with carotid plaque than in those without plaque (median level 1,397 vs. 887 pg/mL, respectively; P = 0.006). There were no significant differences between RA patients with and without carotid plaque with respect to sex, duration of RA, blood pressure, body mass index, smoking, low-density lipoprotein cholesterol, Disease Activity Score-28, van der Heijde-modified Sharp score, and prednisolone dose. After adjusting for age, sex, and C-reactive protein, elevated levels of OPG were still associated with a higher prevalence of carotid plaque in patients with RA (P = 0.038). CONCLUSION: RA patients suffer from accelerated atherosclerosis and also have increased levels of OPG. The serum OPG level is independently associated with carotid plaque.

ABSTRACT

We herein report a 49-year-old Japanese man with relapsing polychondritis (RP) and aseptic meningoencephalitis. Four years ago, the patient was diagnosed with RP. Prednisolone (PSL) was started at 30 mg/day, and the symptoms promptly disappeared. However, cognitive impairment gradually appeared from six months before hospitalization. Methylprednisolone pulse therapy was immediately initiated, followed by administration of PSL at 1 mg/kg/day. Intravenous cyclophosphamide was combined with PSL. After treatment, the patient's cognitive impairment clearly improved. In conclusion, RP rarely causes aseptic meningoencephalitis, highlighting the need for prompt and aggressive immunosuppressive therapy.

ABSTRACT

During the treatment of a patient on hemodialysis with severe coronavirus disease 2019 (COVID-19), the patient was weaned from extracorporeal membrane oxygenation, which was used to treat severe COVID-19 pneumonia. However, the patient's condition worsened after the peak infection phase of COVID-19 because of acute respiratory distress syndrome with suspected hemophagocytic lymphohistiocytosis (HLH). After a bone marrow biopsy confirmed the diagnosis, methylprednisolone pulse therapy, followed by combination therapy (including oral prednisolone and cyclosporine) was immediately administered, and the patient survived. Because HLH can occur a month or more after the onset of COVID-19, even if the viral load is reduced to the point of being undetectable by reverse transcriptase-polymerase chain reaction, it can be considered to correspond to the "post-acute COVID-19 syndrome," which has recently been proposed. Early intervention is necessary, because HLH can be fatal. Therefore, it is important to know that HLH can occur at any stage of COVID-19 and to pay attention to the patient's progress over time, including checking the HScore.

ABSTRACT

Herein, we report the case of a 67-year-old man with severe coronavirus disease (COVID-19) pneumonia and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine breakthrough infection during immunosuppressive therapy for connective tissue disease-related interstitial lung disease (CTD-ILD). The patient received glucocorticoids combined with tacrolimus as maintenance therapy. His serum anti-SARS-CoV-2-immunoglobulin G (IgG) antibody levels were extremely low at the onset of COVID-19 pneumonia, even after the second dose of SARS-CoV-2 mRNA vaccine (BNT162b2). After treatment for COVID-19 pneumonia, the levels of anti-SARS-CoV-2-IgG antibodies increased. These results indicated a lack of the ability to produce neutralising antibodies from immune cells despite the booster vaccination. Therefore, we suggest that advanced-age patients with CTD-ILD receiving immunosuppressive therapy with polypharmacy require consistent personal protection, vaccination of close caregivers, increased awareness, and booster vaccination. Moreover, we recommend that tacrolimus should be withdrawn for a while after vaccination under controlled conditions.

ABSTRACT

We encountered a 57-year-old Japanese woman with encapsulating peritoneal sclerosis (EPS) in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and systemic sclerosis. The patient was admitted to our hospital because of ascites retention. Administration of tocilizumab, an anti-interleukin-6 receptor antibody, for her RA reduced the refractory ascites remarkably; however, she developed sudden acute gastrointestinal bleeding and died a year later. On autopsy, sclerotic thickening of the peritoneum showed diffuse infiltration of podoplanin-positive fibroblast-like cells, and a diagnosis of EPS was made. EPS rarely occurs in SLE, and tocilizumab may be a new treatment candidate for EPS.

ABSTRACT

Since December 2020, coronavirus disease 2019 (COVID-19) vaccines have been distributed in most countries to prevent the onset and aggravation of COVID-19. There is little information regarding the long-term safety of the vaccines. We report three cases and a literature review of new-onset adult-onset Still's disease (AOSD) that occurred following COVID-19 vaccination. Our cases include moderate to severe AOSD, and two were complicated with macrophage activation syndrome. Seventeen cases of new-onset or relapse of AOSD following COVID-19 vaccination, including 14 identified in the literature review and our 3 patients, were all treated successfully with glucocorticoid therapy, immunosuppressive drugs, or biologic agents.

ABSTRACT

We herein report a case of diffuse large B-cell lymphoma (DLBCL) involving multiple renal and bone infiltrations presenting with giant cell arteritis-like (GCA)-like manifestations. One month prior, the present patient had left-sided temporal headache, jaw claudication, and renal failure. The patient was diagnosed with DLBCL based on a renal biopsy. After rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) plus intrathecal methotrexate/cytarabine/prednisone and rituximab, high-dose methotrexate, and cytarabine (R-MA) chemotherapy, the patient's clinical manifestations improved, and complete remission was achieved. DLBCL rarely but occasionally presents with GCA-like manifestations or multiple renal and bone infiltrations, highlighting the need for prompt and aggressive combination chemotherapy.

ABSTRACT

We present the case of a 42-year-old woman with rheumatoid arthritis and Sjögren's syndrome treated with adalimumab who developed immune-mediated necrotizing myopathy (IMNM) and trigeminal neuropathy after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccination. Trigeminal neuralgia and elevated serum creatine kinase levels emerged 12 days post-vaccination, followed by myalgia in the femoral muscles. IMNM was histologically diagnosed. The pathogenesis may involve molecular mimicry between the SARS-CoV-2 spike glycoprotein and autologous tissues triggered by vaccination. This case emphasizes the association between SARS-CoV-2 vaccination, tumor necrosis factor inhibitor, IMNM, and trigeminal neuropathy, as well as the importance of monitoring immune-mediated adverse events following SARS-CoV-2 vaccination in patients with autoimmune disease.

ABSTRACT

Until recently, effector T helper (Th) cells have been classified into two subsets, Th1 and Th2 cells. Since the discovery of Th17 cells, which produce IL-17, much attention has been given to Th17 cells, mainly because they have been implicated in the pathogenesis of various inflammatory diseases. We have performed transcriptome analysis combined with factor analysis and revealed that the expression level of c-Maf, which is considered to be important for Th2 differentiation, increases significantly during the course of Th17 differentiation. The IL-23 receptor (IL-23R), which is important for Th17 cells, is among putative transcriptional targets of c-Maf. Interestingly, the analysis of c-Maf transgenic Th cells revealed that the overexpression of c-Maf did not lead to the acceleration of the early stage of Th17 differentiation but rather to the expansion of memory phenotype cells, particularly with Th1 and Th17 traits. Consistently, mouse wild-type memory Th cells expressed higher mRNA levels of c-Maf, IL-23R, IL-17, and IFN-γ than control cells; in contrast, Maf(-/-) memory Th cells expressed lower mRNA levels of those molecules. Thus, we propose that c-Maf is important for the development of memory Th cells, particularly memory Th17 cells and Th1 cells.

ABSTRACT

Introduction: Most pulmonary vasodilators are administered orally; however, in patients with pulmonary hypertension undergoing gastrointestinal surgery, a switch to parenteral drugs is needed. Parenteral pulmonary vasodilators carry a risk of infection and reduced quality of life owing to long-term central venous catheterization; therefore, it is preferable to switch them to oral vasodilators after surgery. Here, we present the case of a patient with systemic sclerosis complicated by pulmonary hypertension and colon cancer, for which treatment was successfully switched from epoprostenol to selexipag postoperatively. Case Description: A 59-year-old woman, who was diagnosed with mixed group I and III pulmonary hypertension and systemic sclerosis, was on oral triple pulmonary vasodilators for pulmonary hypertension and Raynaud's phenomenon. She was diagnosed as having colon cancer 3 months before admission. Despite the severe pulmonary condition and treatment with oral triple pulmonary vasodilators, colon cancer resection surgery was performed with the management for pulmonary hypertension through multidisciplinary treatments in collaboration with cardiology specialists. Medications for patients with pulmonary hypertension undergoing gastrointestinal surgery need to be switched from oral vasodilators to epoprostenol perioperatively. On postoperative day 19, 0.4 mg/day of selexipag was administered with epoprostenol. Subsequently, the epoprostenol dosage was gradually decreased, and selexipag was increased. On postoperative day 30, the dose of selexipag was increased to 1.2 mg/day and epoprostenol was discontinued. The patient was discharged on postoperative day 40. Conclusion: In our case, transition from epoprostenol to selexipag contributed to a more useful management strategy for systemic sclerosis and pulmonary hypertension in the postoperative period.
