Abstract
Abstract
Background/Aims
The objective of this analysis is to describe the long-term safety profile of upadacitinib (UPA) across rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) from the SELECT clinical program.
Methods
Safety data (cut-off: 30 June 2020) from the UPA SELECT clinical program were compiled for RA (six trials), PsA (two trials), and AS (one trial) for this analysis. Treatment-emergent adverse events (TEAEs; onset on or after first dose and ≤30 days after last dose for UPA and methotrexate [MTX] or ≤ 70 days for adalimumab [ADA]) were summarized for RA (pooled UPA 15 mg once daily [QD], ADA 40 mg every other week [EOW], and MTX), PsA (pooled UPA 15 mg QD and ADA 40 mg EOW), and AS (UPA 15 mg QD). TEAEs are reported as exposure-adjusted adverse event rates (EAERs; events/100 patient-years [E/100 PY]).
Results
In total, 4298 patients (RA, N = 3209; PsA, N = 907; AS, N = 182) received ≥1 dose of UPA 15 mg, totaling 8562 PY of exposure, with the majority of exposure from RA studies. AEs leading to discontinuation were generally similar across all treatment groups (UPA, ADA, and MTX) and patient populations (RA, PsA, and AS). The most common adverse events leading to discontinuation with UPA were pneumonia (RA), psoriatic arthropathy flare or worsening (PsA), and headache (AS). Rates of serious infection and opportunistic infection were generally similar across all treatment groups within each population and across RA, PsA, and AS. Pneumonia was both the most common serious infection and serious AE in RA and PsA. No serious infections were reported in patients with AS. Herpes zoster and increased CPK were reported more often with UPA compared to ADA or MTX, with UPA showing similar rates of herpes zoster across RA, PsA, and AS. Malignancies excluding NMSC were reported at similar rates across all treatment groups and populations. NMSC was not common, with numerically higher rates observed with UPA versus MTX and/or ADA in RA and PsA. Similar rates of adjudicated major adverse cardiovascular events (MACE) and adjudicated venous thromboembolic events (VTE) were observed across all treatment groups, with no events reported in patients with AS. Rates of death reported in these clinical studies were not higher than expected in the general populations. As anticipated for the patient populations, the most common cause of death observed was cardiovascular in nature.
Conclusion
With the exception of herpes zoster, exposure-adjusted adverse event rates were generally similar across UPA, ADA, and MTX in RA, as well as UPA and ADA in PsA. No new safety risks were identified with long-term treatment in RA, PsA, or AS. UPA 15 mg demonstrated a consistent safety profile across RA, PsA, and AS populations in the SELECT clinical program.

Abstract
Abstract
Background/Aims
Filgotinib (FIL), an oral Janus kinase 1 preferential inhibitor, has demonstrated safety and efficacy as treatment for signs and symptoms of RA, and it is approved in Japan and Europe for treatment of RA. Patient characteristics can influence response to RA treatment; this post hoc analysis was performed to determine whether age, body weight (BW), and body mass index (BMI) influenced efficacy.
Methods
Patients from FINCH 1 (F1, n = 1755, inadequate response to methotrexate [MTX-IR]; NCT02889796) or FINCH 3 (F3, n = 1249, MTX-naïve; NCT02886728) were included for analysis of clinical response at week 12 (F1 primary endpoint) or 24 (F3 primary endpoint). Patients were stratified by age (<65, ≥65 years), BW (<60, 60 to < 100, ≥100 kg), and BMI (<25, ≥25 kg/m2). Efficacy was assessed by ACR20, Disease Activity Score-28 <2.6, Clinical Disease Activity Index ≤2.8, Simple Disease Activity Index ≤3.3, Boolean remission, and change from baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI). Selected efficacy endpoints are displayed in Table 1. Patients treated with FIL200+MTX were compared with control arms (F1, placebo+MTX; F3, MTX). Fisher’s exact test was used for binary endpoints; mixed-effects model for repeated measures was used for HAQ-DI. P-values were nominal without adjusting for multiplicity.
Results
FIL200+MTX in MTX-IR patients demonstrated greater efficacy vs placebo+MTX regardless of age, BW, and BMI (Table 1). Apart from the ≥65-year-old subgroup, in which there was no clear pattern, FIL200+MTX in MTX-naïve patients demonstrated greater efficacy vs MTX across subgroups (Table 1). Rates of treatment-emergent adverse events (TEAEs) were greater in the ≥65-year-old subgroup vs the <65-year-old subgroup; there was no discernible pattern between BMI subgroups. Among MTX-naïve patients only, rates of TEAEs were higher in those who weighed ≥100 kg vs lower-weight subgroups.
Conclusion
This exploratory analysis showed FIL200+MTX was efficacious regardless of subgroup characteristics defined by age, BW, or BMI. Most comparisons of FIL200+MTX vs MTX and vs placebo+MTX favored FIL200+MTX.

Abstract
Abstract
Background/Aims
The preferential Janus kinase (JAK)-1 inhibitor filgotinib (FIL) is approved for treatment of moderately to severely active RA in Europe and Japan. We assessed efficacy and safety of FIL in patients (pts) with inadequate response to MTX (MTX-IR) who completed a Phase 3 trial (NCT02889796) and went on to enroll in a long-term extension (LTE; NCT03025308).
Methods
Pts who completed the parent study (PS) on study drug were eligible to enter the LTE. LTE data cutoff was June 1, 2020, and safety data are reported to that date, with median exposure 2.2 years. Efficacy data to W48 are reported for 4 treatment groups (all with background MTX): pts who received FIL 200mg (FIL200) or FIL 100mg (FIL100) in the PS and continued their dose in LTE (FIL200/FIL200, FIL100/FIL100) and ADA pts who were re-randomized, double blind, to FIL200 or FIL100 for LTE (ADA/FIL200, ADA/FIL100). ACR20/50/70 response rates, DAS28[CRP] ≤3.2 and <2.6, and CDAI ≤10 and ≤2.8 are reported. Exposure-adjusted incidence rates (EAIR)/100 pt-years of exposure of treatment-emergent adverse events (TEAEs) and AEs of special interest (AESIs) are summarized.
Results
As of June 1, 2020, 522/571 (91%) FIL200/FIL200, 502/570 (88%) FIL100/FIL100, 118/128 (92%) ADA/FIL200, and 115/130 (89%) ADA/FIL100 pts were still on study drug. LTE baseline (BL) disease characteristics were similar between groups: mean duration of RA was approximately 8.7 years; DAS28(CRP) was 2.55 and mean MTX dosage was 15.0 mg/week. Proportions of pts achieving ACR20/50/70, DAS28(CRP) ≤3.2, <2.6, and CDAI ≤10, ≤2.8 were maintained in all 4 LTE groups through W48. Numerically greater proportions of pts met response criteria at W48 in the FIL200 groups vs FIL100, regardless of PS treatment. TEAEs, serious AEs, and AEs Grade ≥3 were largely comparable between groups and lowest in ADA/FIL100 pts. There were 3 deaths in each PS FIL group and 2 in each PS ADA group; EAIRs for deaths were lower for FIL/FIL groups compared with ADA/FIL groups. Opportunistic infections occurred only in FIL/FIL pts (2 in each group). Nonmelanoma skin cancer (NMSC; n = 5) occurred only in FIL/FIL groups, and malignancies excluding NMSC occurred in all groups except ADA/FIL100.
Conclusion
During the LTE through W48, response rates were maintained for FIL/FIL and ADA/FIL pts. Though there were differences between LTE groups, safety was largely comparable and consistent with that observed in the PS and in previously reported results of safety data from 7 trials: rates of AESIs were low, and all confidence intervals were overlapping. Limitation: the LTE was not formally randomized for comparison between FIL/FIL and ADA/FIL treatment groups, the groups were of unequal size, and the switch from ADA to FIL for LTE was by design, rather than based on disease activity.

Impact of serum interleukin-22 as a biomarker for the differential use of molecular targeted drugs in psoriatic arthritis: a retrospective study. Arthritis Res Ther 2022; 24:86. [PMID: 35428323 PMCID: PMC9011943 DOI: 10.1186/s13075-022-02771-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Accepted: 03/22/2022] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND We explored whether serum cytokines could be used as biomarkers for optimal use of tumor necrosis factor inhibitors (TNF-i) and interleukin (IL)-17 inhibitors (IL-17-i) in patients with psoriatic arthritis (PsA). METHODS In cohort 1 (47 patients treated with IL-17-i [n=23] or TNF-i [n=24] for ≥1 year), we identified serum cytokines that predicted the achievement of Disease Activity in Psoriatic Arthritis-remission (DAPSA-REM), Psoriasis Area and Severity Index (PASI) 90, and Minimal Disease Activity after 1 year of TNF-i or IL-17-i therapy. Subsequently, we developed treatment strategies based on the identified cytokines; initiation of IL-17-i therapy in patients with low IL-22 concentrations (IL-22 <0.61376 pg/ml) and TNF-i therapy in patients with high IL-22 concentrations (0.61376< IL-22 pg/ml). In cohort 2 (34 patients), treatment responses were compared between the strategic treatment group (n=17), which was treated based on the treatment strategies, and the mismatched treatment group (n=17) to verify the validity of the treatment strategies developed using serum cytokines as biomarkers. RESULTS In cohort 1, serum IL-22 concentration was identified as a predictor of DAPSA-remission after 1 year of IL-17-i therapy. Regarding treatment strategies, we selected TNF-i for patients with high IL-22 concentrations and IL-17-i for those with low IL-22 concentrations. There were no significant differences in the baseline characteristics between the strategic and mismatched treatment groups. Regarding treatment effects, activity significantly improved at 1 year in both groups. Upon comparison of the treatment effects, the rate of achieving DAPSA-REM and Minimal Disease Activity at month 12 was significantly higher in the strategic treatment group. CONCLUSIONS The results of this pilot study suggest that IL-22 may be a biomarker of treatment response to TNF-i and IL-17-i in patients with PsA. Further large-scale studies in independent, prospectively collected datasets are required to verify that IL-22 is indeed a biomarker of treatment response in these patients.

Abstract
We had two cases of trisomy 8-positive myelodysplastic syndrome (MDS) with incomplete Behçet's disease (BD) in which the remissions of both diseases were maintained by allogeneic stem cell transplantation (allo-SCT). Among MDS with BD patients, sometimes it is difficult to control the symptoms of BD with standard therapies, such as corticosteroids and TNF inhibitors. Although there should be careful consideration regarding indications for transplantation, our two cases, in which refractory BD was completely controlled by allo-SCT, suggest that allo-SCT can be one of the treatment options for higher risk MDS with BD patients.

Abstract
The patient was a 74-year-old man who was admitted to our hospital for fever, purpura, abdominal pain, and bilateral numbness. Although the patient tested negative for anti-neutrophil cytoplasmic antibody (ANCA), he presented with an elevated peripheral eosinophil count, increased inflammatory responses, duodenitis, cholecystitis, lung lesions, renal disorder, and peripheral neuropathy. The skin biopsy findings revealed vasculitis. Thus, the patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). Given the advanced age of the patient, in addition to the poor general condition and hepatic and renal dysfunction, administration of immunosuppressants was considered to pose a high risk. After obtaining informed consent, remission induction therapy was initiated with mepolizumab (300 mg/M) in combination with high-dose corticosteroid therapy (equivalent to 70 mg/day of prednisolone). After treatment initiation, eosinophil counts and inflammatory responses decreased. Moreover, the abdominal pain and purpura resolved, and renal/hepatic dysfunction and peripheral neuropathy also improved. While the corticosteroid dose was subsequently reduced, no relapse was observed. Approximately 2 years later, the corticosteroid was discontinued. After the discontinuation of the corticosteroid, the patient continued treatment with mepolizumab alone and has remained in remission for approximately 6 months. Therefore, mepolizumab may be useful as a remission induction therapy in ANCA-negative EGPA resistant to steroids.

Abstract
AIMS The aim of this study was to define the relationship between time in range (TIR) and hemoglobin A1c (HbA1c) levels in patients with type 2 diabetes mellitus (T2DM). METHODS The glycemic profile of 999 Japanese patients was analyzed with FreeStyle Libre Pro Continuous Glucose Monitoring (FLP-CGM) while they continued their prescribed glucose-lowering medications. FLP-CGM data recorded over 8 consecutive days were analyzed. RESULTS The regression model for HbA1c on TIR was HbA1c = 9.4966-0.0309 × TIR. The predicted HbA1c level for TIR of 70% was 7.33% and is higher than reports subjecting mostly T1DM. The TIR corresponding to HbA1c 7.0% was 80.64%. The patients with low TIR tended to have long duration of diabetes, used high dose of daily insulin, high body mass index, high HbA1c, liver dysfunction and high triglyceride. Relatively higher percentages of patients of this group used sulfonylureas, glucagon like peptide-1 receptor agonists and insulin. CONCLUSIONS Our data showed predicted HbA1c corresponding to TIR is largely depends on study population, thus is not uniform. Our results provide new insights on the management of T2DM. However, caution should be exercised in extending the HbA1C-TIR relationship using FLP-CGM to any other sensors since there could be a risk of hypoglycemia in doing so.

Abstract
Objectives To characterise the efficacy and safety of anifrolumab in patients with systemic lupus erythematosus (SLE) according to interferon gene signature (IFNGS), demographic and clinical subgroups. Methods We performed post hoc analyses of pooled data from the 52-week phase III TULIP-1/TULIP-2 placebo-controlled trials of intravenous anifrolumab in moderate-to-severe SLE. Outcomes were assessed in predefined subgroups: IFNGS (high/low), age, sex, body mass index, race, geographic region, age of onset, glucocorticoid use, disease activity and serological markers. Results In pooled data, patients received anifrolumab 300 mg (360/726) or placebo (366/726); 82.6% were IFNGS-high. IFNGS-high patients had greater baseline disease activity and were more likely to have abnormal serological markers versus IFNGS-low patients. In the total population, a greater proportion of patients treated with anifrolumab versus placebo achieved British Isles Lupus Assessment Group-based Composite Lupus Assessment (BICLA) response at week 52 (difference 16.6%; nominal p<0.001). BICLA response treatment differences with anifrolumab versus placebo were comparable to the total population across most predefined subgroups, including subgroups for baseline glucocorticoid dosage (<10/≥10 mg/day prednisone/equivalent) and for clinical disease activity (SLE Disease Activity Index 2000 score <10/≥10). Subgroups with larger treatment differences included IFNGS-high patients (18.2%), patients with abnormal baseline serological markers (23.1%) and Asian patients (29.2%). The safety profile of anifrolumab was similar across subgroups. Conclusions Overall, this study supports the consistent efficacy and safety of anifrolumab across a range of patients with moderate-to-severe SLE. In a few subgroups, small sample sizes limited conclusions from being drawn regarding the treatment benefit with anifrolumab. Trial registration number NCT02446912, NCT02446899.

Abstract
The establishment of precision medicine is considered particularly important in heterogeneous autoimmune diseases (e.g., psoriatic arthritis, systemic lupus erythematosus), which reveal clinical and molecular heterogeneity. The selection of optimal treatment strategies for individual patients may be more important and complex in autoimmune diseases than in other diseases. Two factors are important in precision medicine: patient stratification and use of targeted. When both factors work, patients are likely to have good outcomes. However, research into precision medicine and its practice in systemic autoimmune diseases is lacking. In contrast, the usefulness of peripheral immune cell phenotyping in the evaluation of immunological characteristics and stratification into subgroups of individual patients with systemic autoimmune diseases such as immunoglobulin 4-related disease, systemic lupus erythematosus, and anti-neutrophil cytoplasmic antibody-related vasculitis was reported. Furthermore, the potential of precision medicine using biological disease-modifying antirheumatic drugs based on peripheral immune cell phenotyping was recently demonstrated for psoriatic arthritis in the clinical setting. Precision medicine has not yet been sufficiently investigated in real world clinical settings. However, a dawn of precision medicine has emerged. We should shed further light on precision medicine in PsA and other autoimmune diseases. Here, we first review the usefulness of peripheral immune cell phenotyping in systemic autoimmune diseases and the potential of precision medicine in PsA based on this method.

Abstract
Objective To study the pathophysiological differences of EGPA and IgG4-related disease (RD) by clarifying their clinical, pathological and immunological features. Methods Clinical and pathological findings were compared in patients with EGPA and IgG4-RD. Peripheral blood mononuclear cells were used for comprehensive flow cytometric analysis. Results An elevation of the IgG4 level was found in all EGPA cases, with the accompanying pathological findings of lymphocytic infiltration and fibrosis observed in 30.8% patients, and the elevation of IgG4/IgG ratio in 61.5% patients. However, actual IgG4 levels, as well as the degree of the infiltration of IgG4-positive plasma cells, were still higher in patients with IgG4-RD than patients with EGPA. Examination by ACR/EULAR classification criteria showed only 13.6% of the EGPA patients met entry criteria, while all of them met the exclusion criteria. In regard to the immunophenotyping, EGPA patients had increases in activated CD4 and CD8 T cells compared with the healthy controls. However, no such similar changes occurred in IgG4-RD patients. On the other hand, both the EGPA and IgG4-RD patient groups had correlated increased plasmablasts and Tfh. These results indicate the presence of two axes: namely, the activation of T cells and that of B cells. Both axes are present in EGPA, but the T cell activation axis was not observed in IgG4-RD. Conclusions The elevation of serum IgG4 as well as pathological IgG4 infiltration are not specific. Meanwhile, EGPA and IgG4-RD differ in immunological phenotypes, indicating the possible importance of the predominant activation of T cells in the development of vasculitis.

Abstract
Background Short-term mortality and incidence of cerebrovascular and cardiovascular events (C-CVE) during hospitalization of patients with severe herpes zoster (HZ) have not been sufficiently investigated. We aimed to investigate short-term prognosis and incidence of C-CVE associated with HZ in hospitalized patients. Methods This retrospective cohort study from April 2016 to March 2018 included HZ inpatient cases selected from the Diagnosis Procedure Combination database—a Japanese nationwide inpatient database. HZ and C-CVE were diagnosed based on the 10th revision of the International Classification of Diseases and Injuries codes. The definition of primary exposure was that treatments were initiated within 7 days of admission, and antivirals were administered for ≥7 days. Main Outcomes were in-hospital deaths and C-CVE onset after hospitalization. Results Among 16,811,501 in-hospital cases registered from 1,208 hospitals, 29,054 cases with HZ were enrolled. The median age was 71.0 years, 15,202 cases (52.3%) were female, and the HZ types were the central nervous system (n=9,034), disseminated (n=3,051), and ophthalmicus (n=1,069) types. There were 301 (1.0%) in-hospital deaths and 385 (1.3%) post-hospitalization onset of C-CVE. The 30-day in-hospital survival rates with or without underlying disease were 96.8% and 98.5%, respectively. Age ≥75 years (hazard ratio [HR], 2.18; 95% confidence interval [CI], 1.55–3.05), liver cirrhosis or hepatic failure (HR, 5.93; 95% CI, 2.16–16.27), chronic kidney disease (HR, 1.82; 95% CI, 1.24–2.68), heart failure (HR, 1.65; 95% CI, 1.22–2.24), and old cerebrovascular events (HR, 1.92; 95% CI, 1.10–3.34) were associated with poor short-term prognosis. Age ≥75 years (odds ratio [OR], 1.70; 95% CI, 1.29–2.24), diabetes (OR, 1.50; 95% CI, 1.19–1.89), dyslipidemia (OR, 1.95; 95% CI, 1.51–2.51), hyperuricemia (OR, 1.63; 95% CI, 1.18–2.27), hypertension (OR, 1.76; 95% CI, 1.40–2.20), heart failure (OR, 1.84; 95% CI, 1.32–2.55), and glucocorticoid administration (OR, 1.59; 95% CI, 1.25–2.01) were associated with increased risks for in-hospital C-CVE onset. Conclusions The underlying diseases that could influence the short-term mortality of severe HZ were identified. Glucocorticoid is a possible risk factor for the in-hospital onset of C-CVE after severe HZ development.

Abstract
Backgrounds Treatment of difficult-to-treat rheumatoid arthritis (D2T RA) is one of the greatest unmet needs in rheumatology. This study aims to find out preferable treatment options for a group of D2T RA patients who are refractory to multiple biologic and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs). Methods Data were obtained from patients enrolled in the FIRST Registry who started either TNF inhibitor (TNFi), interleukin-6 receptor inhibitor, cytotoxic T-lymphocyte–associated antigen-4 immunoglobulin, or Janus-kinase inhibitor (JAKi) in the period of August 2013 to December 2020. Those who failed to ≥ 2 and ≥ 3 b/tsDMARDs were categorised as D2T RA and very D2T RA (vD2T RA), respectively. Change in Clinical Disease Activity Index (CDAI) and Health Assessment Questionnaire Disability Index were compared among the groups using propensity-based inverse probability treatment weighted (IPTW) method. Results Of 2128 cases included, 353 were categorised as D2T RA. Among the D2T RA, 106 were identified as vD2T RA. JAKi showed a significant improvement in CDAI in the patients with D2T RA and vD2T RA, compared to IPTW-adjusted patients treated with the other 3 regimens. Latent class analysis of the trajectories of treatment response revealed that the proportion of a group of patients who showed poor response was lower among the JAKi subgroup than among those with other subgroups. This superiority of JAKi was more apparent among methotrexate- and glucocorticoid-free individuals. The hazard ratio of severe adverse events was comparable among the four treatment subgroups in both the D2T RA and b/tsDMARD-naïve groups. Conclusions This study compared responsiveness to different classes of b/tsDMARDs among D2T RA and vD2T RA patients who were refractory to multiple b/tsDMARDs. The results suggest JAKi is a preferable treatment choice for this type of D2T RA.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease that causes multiple organ damage in women of childbearing age and has a relapsing-remitting course. SLE is caused by the interaction between genetic and environmental factors, however, its underlying triggers remain unknown. Among the environmental factors, the involvement of infections as a trigger for SLE, especially those of viral etiology, has been widely reported. Human endogenous retroviruses (HERVs) may put patients at a genetic predisposition to SLE, while the Epstein-Barr virus (EBV) may play a role as an environmental factor that triggers the development of SLE. It has been suggested that EBV-infected B-cells may become resistant to apoptosis, resulting in the activation, proliferation, and antibody production of autoreactive B-cells, which cause tissue damage in SLE. However, the interaction between the virus and immune cells, as well as the impact of the virus on the differentiation and dysfunction of immune cells, remain unclear. In this review, we focus on the relationship between the development and pathogenesis of SLE and viral infections, as well as the mechanism of SLE exacerbation via activation of immune cells, such as B-cells, based on the latest findings.

Abstract
OBJECTIVES To assess the efficacy and safety of branched chain amino acids (BCAAs) in the treatment of PM/DM prior to official approval of their use in Japan. METHODS Treatment naïve adults with PM/DM were enrolled in a randomized, double-blind trial to receive either TK-98 (drug name of BCAAs) or placebo in addition to conventional treatment. After 12 weeks, patients with an average manual muscle test (MMT) score <9.5 were enrolled in an open label extension study for a further 12 weeks. The primary end point was the change of the MMT score at 12 weeks. The secondary end points were the clinical response and the change of functional index (FI). RESULTS Forty-seven patients were randomized either to the TK-98 (n = 24) or placebo (n = 23) groups. The changes of MMT scores at 12 weeks were 0.70±0.19 (mean±SEM) and 0.69±0.18, respectively (P = 0.98). Thirteen patients from the TK-98 group and 12 from the placebo group were enrolled in the extension study. The MMT scores in both groups improved similarly. The increase of the FI scores of the shoulder flexion at 12 weeks was significantly greater in the TK-98 group (27.9±5.67 vs. 12.8±5.67 for the right shoulder flexion, and 27.0±5.44 vs. 13.4±5.95 for the left shoulder [P < 0.05]). Frequencies of adverse events upto 12 weeks were similar. CONCLUSION BCAAs showed no effect on the improvement of the muscle strength evaluated by MMT and the clinical response. However, they were partly effective for improving dynamic repetitive muscle functions. TRIAL REGISTRATION UMIN-CTR Clinical Trial, https://center6.umin.ac.jp/, UMIN000016233.

Abstract
INTRODUCTION The pathogenesis of systemic lupus erythematosus (SLE) involves abnormalities in both acquired and innate immune system, which is mediated by numerous cytokines. Janus kinase (JAK) plays important roles in the signaling pathways of those cytokines and is an attractive therapeutic target for SLE. Currently, multiple clinical trials using JAK inhibitors with different selectivities for JAK family proteins are being conducted in SLE. AREA COVERED In this article, we provide an overview of the pathological relevance of JAK and the clinical implications of JAK inhibitors in SLE based on recent reports. EXPERT OPINION JAK inhibitors have the potential to modulate various immune networks through a variety of mechanisms, potentially regulating the complex immunopathogenesis in SLE. SLE is a clinically and immunologically heterogeneous disease; therefore, precision medicine is required to maximize the efficacy of JAK inhibitors. Further studies are needed to determine their risk-benefit ratio and selection of the most appropriate patients for JAK inhibitors.

[PMID: 35121639 PMCID: PMC8819784 DOI: 10.1136/rmdopen-2021-002012] [Citation(s) in RCA: 35] [Impact Index Per Article: 17.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Accepted: 01/13/2022] [Indexed: 12/29/2022] Open
Abstract
Objectives To assess the long-term safety and efficacy of the Janus kinase inhibitor upadacitinib versus adalimumab over 3 years in the ongoing long-term extension (LTE) of SELECT-COMPARE, a randomised controlled phase 3 trial of patients with active rheumatoid arthritis and inadequate response to methotrexate (MTX). Methods Patients on stable background MTX were randomised 2:2:1 to upadacitinib 15 mg, placebo or adalimumab 40 mg. Patients with an insufficient response were switched by week 26 from placebo to upadacitinib, upadacitinib to adalimumab or adalimumab to upadacitinib. Patients who completed the 48-week double-blind period could enter an LTE for up to 10 years. Safety and efficacy results were analysed here through 3 years. Treatment-emergent adverse events (AEs) were summarised based on exposure to upadacitinib and adalimumab. Efficacy was analysed by original randomised groups (non-responder imputation), as well as separately by treatment sequence (as observed). Results Rates of several AEs were generally comparable between upadacitinib and adalimumab, including AEs leading to discontinuation, serious infections and serious AEs, malignancies, major adverse cardiac events, venous thromboembolism and deaths. Consistent with earlier results, herpes zoster, lymphopaenia, hepatic disorder and CPK elevation were reported at higher rates with upadacitinib versus adalimumab. In terms of efficacy, upadacitinib continued to show numerically better clinical responses than adalimumab over 3 years across all endpoints, including low disease activity and remission. Conclusion The safety profile of UPA 15 mg was consistent with previous study-specific and integrated safety reports. Higher levels of clinical response continued to be observed with upadacitinib versus adalimumab through 3 years of treatment.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic autoimmune disease requiring long-term treatment. Upadacitinib (UPA), a Janus kinase (JAK) inhibitor, is a new treatment for RA. The benefit-risk profile of a medication is best understood by evaluating the number needed to treat (NNT) and the number needed to harm (NNH). This analysis evaluated the comparative risk-benefit of UPA versus adalimumab (ADA). METHODS Post-hoc analyses were performed using data from the SELECT-COMPARE trial of UPA versus placebo (PBO) and UPA versus ADA among patients with active RA who remained on stable methotrexate (MTX) treatment and had an inadequate response; patients who failed to achieve response were rescued by predefined criteria-PBO or ADA switch to UPA, and UPA switch to ADA (all patients on PBO were switched to UPA at week 26). This analysis assessed efficacy and adverse events of special interest (AESIs) at week 26, 48, and 156 (3 years). NNT and NNH (95% confidence intervals) values were calculated between UPA versus ADA for all time points, and between UPA versus PBO for week 26. NNT and NNH values were applied to a hypothetical cohort of 100 patients to estimate the comparative efficacy and safety profiles. RESULTS UPA consistently showed greater efficacy than ADA, as evidenced by NNT values < 10 for achievement of Disease Activity Score in 28 joints based on C-reactive protein (DAS28-CRP) of < 2.6 and ≤ 3.2, respectively, and functional improvement. Based on indices for disease assessment other than the DAS28-CRP, remission outcomes were higher with UPA versus ADA over 26 weeks (NNTs: 7-12), 48 weeks (NNTs: 9-16), and 156 weeks (NNTs: 9-15). With the exception of herpes zoster, other AESIs demonstrated a similar risk with UPA versus ADA. CONCLUSION In patients with active RA despite MTX use, UPA demonstrated an incremental achievement of clinical outcomes compared to ADA together with a similar profile of AESIs with ADA (with the exception of herpes zoster).

Abstract
In the treatment of rheumatoid arthritis (RA), Janus kinase inhibitors (jakinibs) represent an emerging class of targeted therapies in addition to biologics. The number of jakinibs has been growing and as of 2020, filgotinib was the latest jakinib to enter the international market for treating RA. Filgotinib has demonstrated preferential inhibition of JAK1-dependent cytokine signaling in in vitro assays. It has been evaluated in the DARWIN (phase 2) and FINCH (phase 3) series of clinical studies for treating patients with moderately-to-severely active RA. Filgotinib received regulatory approval in Japan and Europe in September 2020, while in August 2020 the United States Food and Drug Administration requested additional data from two ongoing clinical studies assessing the potential impact of filgotinib on sperm parameters. This article will review the pharmacological properties, efficacy, and safety of filgotinib as demonstrated in clinical studies. Expert opinion will be provided on jakinibs for RA treatment from the viewpoints of basic research and clinical practice.

Abstract
The four Janus kinase (JAK) proteins and seven signal transducer and activator of transcription (STAT) transcription factors mediate intracellular signal transduction downstream of cytokine receptors, which are implicated in the pathology of autoimmune, allergic and inflammatory diseases. Development of targeted small-molecule therapies such as JAK inhibitors, which have varied selective inhibitory profiles, has enabled a paradigm shift in the treatment of diverse disorders. JAK inhibitors suppress intracellular signalling mediated by multiple cytokines involved in the pathological processes of rheumatoid arthritis and many other immune and inflammatory diseases, and therefore have the capacity to target multiple aspects of those diseases. In addition to rheumatoid arthritis, JAK inhibition has potential for treatment of autoimmune diseases including systemic lupus erythematosus, spondyloarthritis, inflammatory bowel disease and alopecia areata, in which stimulation of innate immunity activates adaptive immunity, leading to generation of autoreactive T cells and activation and differentiation of B cells. JAK inhibitors are also effective in the treatment of allergic disorders, such as atopic dermatitis, and can even be used for the COVID-19-related cytokine storm. Mechanism-based treatments targeting JAK-STAT pathways have the potential to provide positive outcomes by minimizing the use of glucocorticoids and/or non-specific immunosuppressants in the treatment of systemic immune-mediated inflammatory diseases.

Abstract
Objective To compare the outcome of various treatment de-escalation regimens in patients with RA who achieved sustained remission. Methods At period 1, 436 RA patients who were treated with MTX and bDMARDs and had maintained DAS28(ESR) at <2.6 were divided into five groups based on shared patient/physician decision-making; continuation, dose reduction and discontinuation of MTX or bDMARDs. At end of year 1, patients who achieved DAS28(ESR) <3.2 were allowed to enrol in period 2 for treatment using the de-escalation regimens for another year. The primary and secondary endpoints were the proportion of patients with DAS28(ESR) <2.6 at year 1 and 2, respectively. Results Based on shared decision-making, 81.4% elected de-escalation of treatment and 48.4% selected de-escalation of MTX. At end of period 1, similar proportions of patients maintained DAS28(ESR) <2.6 (continuation, 85.2%; MTX dose reduction, 79.0%; MTX-discontinuation, 80.0%; bDMARD dose reduction, 73.9%), although the rate was significantly different between the continuation and bDMARD-discontinuation. At end of period 2, similar proportions of patients of the MTX groups maintained DAS28(ESR) <2.6 (continuation or de-escalation), but the rates were significantly lower in the bDMARD-discontinuation group. However, half of the latter group satisfactorily discontinued bDMARDs. Adverse events were numerically lower in MTX and bDMARD-de-escalation groups during period 1 and 2, compared with the continuation group. Conclusions After achieving sustained remission by combination treatment of MTX/bDMARDs, disease control was achieved comparably by continuation, dose reduction or discontinuation of MTX and dose reduction of bDMARDs at end of year 1. Subsequent de-escalation of MTX had no impacts on disease control but decreased adverse events in year 2.

Abstract
A 40-year-old female patient was referred to our department with a complaint of postprandial hypoglycemia. We performed a 75g oral glucose tolerance test, and the patient was diagnosed as having impaired glucose tolerance with a 1-hour blood glucose of 245 mg/dl and a 2-hour blood glucose of 196 mg/dl. The patient also showed hypoglycemia with a 6-hour blood glucose of 46 mg/dl, and delayed hypersecretion of insulin, which was diagnosed as reactive hypoglycemia. The patient was diagnosed as having reactive hypoglycemia with delayed hypersecretion of insulin. She was given dietary guidance to avoid simple carbohydrates, and voglibose 0.6 mg was started for glucose intolerance and reactive hypoglycemia. The frequency of hypoglycemic symptoms decreased for a while, but gradually increased again. An interview revealed that the frequency of hypoglycemia was high at 2-3 days before menstruation, and Flash Glucose Monitoring (FGM) was applied to check the blood glucose fluctuation before and after menstruation. Her postprandial hyperglycemia worsened with FGM, and reactive hypoglycemia appeared 3 days before menstruation, while postprandial hyperglycemia improved and reactive hypoglycemia disappeared 4 days after menstruation. The frequency of hypoglycemia was reduced by instructing the patient to take voglibose before menses and to eat a supplementary meal after lunch a few days before menses. There have been no reports on the evaluation of reactive hypoglycemia exacerbated before menstruation by FGM. The menstrual cycle should be considered in the diagnosis, evaluation, and treatment of reactive hypoglycemia.

Abstract
AIM To clarify the relationship between ambulatory glucose profile (AGP) indexes and standardized continuous glucose monitoring (CGM) metrics in patients with type 2 diabetes (T2D). METHODS This is an exploratory, cross-sectional analysis of baseline data collected from a prospective, multicentre, 5-year follow-up observational study conducted and published previously by our group. The study participants were 999 outpatients with T2D who used CGM at baseline, and had no apparent history of cardiovascular disease. We investigated the relationship between average interquartile range (IQR) and time in range (TIR). We also calculated, for the first time, the cutoff values to achieve the TIR target values. RESULTS In both the TIR more than 70% and TIR more than 90% achievement groups, the average IQR was notably small compared with the non-achievement groups. Particularly in comparison of the TIR quartiles, the average IQR became significantly smaller as the TIR became larger. The average IQR correlated negatively with TIR, and the cutoff values for TIR of more than 70% achievement and TIR of more than 90% achievement were an average IQR (>70%/>90%) of 2.13/1.85 mmol/L. CONCLUSION Our results showed a negative correlation between TIR and the range of blood glucose variations visually represented in AGP. The results also showed that the range of blood glucose variations in AGP is associated with indices of intraday and interday blood glucose variations and also with hypoglycaemia. Our results may provide new perspectives in the assessment and application of AGP in the clinical setting.

Abstract
Granulomatosis with polyangiitis (GPA) is characterized by necrotizing granulomatous lesions and is classified as ANCA-associated vasculitis (AAV). We herein report a case of GPA that was remitted by resection of a pulmonary lesion without immunosuppressive therapy. We detected activated neutrophils and neutrophil extracellular traps (NET) formation in resected lung tissue by immunofluorescence. Activated neutrophils and NETs might be involved in the pathophysiology of AAV and induce the vicious cycle of ANCAs and NETs. In cases of GPA with no other severe lesions, the reevaluation of the disease activity after diagnostic resection is crucial for considering the need for immunosuppressive therapy.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that affects multiple organs. In particular, the presence of renal involvement, known as lupus nephritis, is a major determinant of prognosis. Conventional treatments for SLE include hydroxychloroquine, glucocorticoid and immunosuppressive agents. However, the use of such non-specific drugs increases the risk of side effects, such as infections. Soluble B-cell-activating factor (BAFF), belonging to the tumour necrosis factor family, is produced by dendritic cells and induces class switching of B cells and differentiation into antibody-producing cells. International phase III studies demonstrated the efficacy and safety of belimumab (a monoclonal antibody against soluble BAFF) not only in patients with SLE, but also in those with active lupus nephritis. There were no significant differences between the belimumab and placebo groups in the incidence of adverse events, including serious events and events necessitating drug cessation. Thus, belimumab could become an alternative induction treatment for lupus nephritis. This article describes the pathogenesis of SLE and lupus nephritis, and reviews the results of recent phase III trials of belimumab and its promising role for the treatment of patients.

Abstract
OBJECTIVES We compared the treatment effectiveness between guselkumab and adalimumab in patients with pustulotic arthro-osteitis (PAO). In addition, we performed peripheral blood immunophenotyping to elucidate the immunological background and analyzed the impact of therapeutic drugs to verify the validity of immunological phenotypes as therapeutic targets. METHODS Patients were treated with guselkumab 100 mg (guselkumab group; n = 12) and adalimumab 40 mg (adalimumab group; n = 13). Arthritis disease activity, skin lesion activity, and patient-reported outcomes (PROs) were evaluated and compared between the two groups. The retention rate and adverse events were evaluated. Comprehensive phenotyping of peripheral immune cells was performed in both groups, and phenotypes were compared before and after treatment. RESULTS At 6 months, both groups showed significant improvement in arthritis disease activity and PROs. In the guselkumab group, skin symptoms significantly improved. The 6-month continuation rates were 91.7% (11/12) and 69.2% (9/13) in the guselkumab and adalimumab groups, respectively. Adverse events occurred in 2/12 and 5/13 patients in the guselkumab (16.7%) and adalimumab (38.5%) groups, respectively. Peripheral blood immunophenotyping showed that the proportion of activated T helper (Th) 1 cells was significantly lower in patients with PAO than in healthy controls and that the proportion of activated Th17 cells was significantly higher in patients with PAO, which significantly decreased after treatment with guselkumab. CONCLUSION Although guselkumab and adalimumab have comparable efficacy for PAO, their impact on immunophenotypes varies.

Abstract
Objectives The efficacy of belimumab (BEL) during maintenance therapy in patients with SLE remains unclear in the real-life clinical setting. This study investigated the efficacy and safety of BEL in patients with SLE during maintenance therapy. Methods In this retrospective observational study, maintenance therapy was defined as low-dose glucocorticoid (GC) therapy (prednisolone equivalent dose of ≤0.2 mg/kg/day) in patients with a Safety of Estrogens in Lupus Erythematosus National Assessment-SLE Disease Activity Index (SELENA-SLEDAI) score <10. Participants comprised patients with SLE on HCQ or MMF [standard-of-care (SoC) group: n = 103] and those on BEL plus SoC (BEL+SoC group: n = 100). Selection bias was minimized using propensity score-based inverse probability of treatment weighting (IPTW). GC dose trajectories were modelled using growth mixture modelling (GMM). The primary end point was GC dose at 52 weeks. Results No significant difference was observed in patient characteristics between the two groups after IPTW adjustment. The BEL+SoC group exhibited a significant decrease in GC dose. GC dose at 52 weeks and relapse rate were significantly lower in the BEL+SoC group than in the SoC group. The proportion of patients in one of four groups defined by GMM for which GC dose was tapered to 0 mg within 52 weeks (GC tapering-discontinuation group) was significantly higher in the BEL+SoC group than in the SoC group. In the BEL+SoC group, low SELENA-SLEDAI score and low GC dose at baseline were associated with being GC dose-tapering discontinuation. Conclusion The present study suggests that BEL is suitable for patients with SLE during maintenance therapy.

Abstract
Through treatment with biological DMARDs (bDMARDs) or targeted synthetic (tsDMARDs) such as Janus kinase (JAK) inhibitors in addition to MTX, clinical remission has become a realistic therapeutic goal for the majority of patients with RA, and sustained remission facilitates prevention of joint damage and physical dysfunction. Long-term safety and sustained inhibition of structural changes and physical dysfunction by bDMARDs have been reported. The development of next-generation bDMARDs and expansion of their indications to various autoimmune diseases are expected. Five JAK inhibitors show comparable efficacy to bDMARDs, and the latest ones are effective for overcoming difficult-to-treat RA regardless of prior medications. Patients treated with JAK inhibitors should be adequately screened and monitored for infection, cardiovascular disorders, thrombosis, malignancies and so on. Advances in therapeutic strategies, including the differential use of therapeutic drugs and de-escalation of treatment after remission induction, are prioritized.

Abstract
OBJECTIVES Anaemia is a frequent extra-articular manifestation in rheumatoid arthritis (RA); haemoglobin level changes are associated with changes in disease activity. This post-hoc analysis assessed potential relationships between haemoglobin and disease activity in Japanese patients with RA, enrolled in the KAKEHASI study (NCT02293902). METHODS In this study, adult patients with moderate-to-severe active RA, who had an inadequate response to methotrexate, were randomised to subcutaneous sarilumab 150 mg every 2 weeks (q2w) or 200 mg q2w or placebo for 24 weeks. Post-hoc analyses were conducted on changes in haemoglobin and proportion of anaemic patients, using a mixed-effects model for repeated measures assuming an unstructured covariance. Relationships between haemoglobin and efficacy measures were explored. RESULTS At baseline, nearly half of patients had anaemia, defined by World Health Organization criteria (haemoglobin <12 g/dL, female; or <13 g/dL, male). At Week 24, the least squares mean change in haemoglobin levels was greater in sarilumab groups than for placebo (150 mg: 1.23 g/dL, 200 mg: 1.19 g/dL, placebo: 0.17 g/dL; p=0.0002 for both doses vs. placebo). By Week 24, the proportion of patients with anaemia was 17.8%, 22.9%, and 30.1% for sarilumab 150 mg, 200 mg, and placebo, respectively. CONCLUSIONS In Japanese patients with RA, both doses of sarilumab were associated with greater improvement in haemoglobin levels and reduction in proportion of patients with anaemia, compared with placebo. Sarilumab may be a suitable treatment for patients with RA and anaemia.

Abstract
OBJECTIVE Since the pathological features of IgG4-related disease (IgG4-RD) include lymphocyte infiltration and fibrotic changes in the lesions, we investigated the significance of fractalkine (CX3CL1) and lymphocyte subsets in patients with IgG4-RD. METHODS Peripheral blood and biopsied samples were obtained from healthy controls (HCs, n = 10), rheumatoid arthritis (RA, n = 10), and IgG4-RD patients (n = 16) and were analyzed by flow cytometry, immunohistology and costimulation assays. RESULTS Peripheral CX3CR1+ CD4+ T cells had an approximately threefold increase in the IgG4-RD patients (15.4%), compared with the HCs (5.0%). In addition, CX3CR1+ CD4+ T cells were localized in the salivary glands of the IgG4-RD patients but not in those with Sicca syndrome. CX3CR1 was induced on 20% of CD4+ T cells after T cell receptor (TCR) simulation with IL-12 for five days-culture. CX3CR1+ T cells showed high expression of both CXCR5 and CXCR3. Moreover, they co-expressed Bcl-6 and T-bet, the master transcription factors for T helper 1 (Th1) and T follicular helper (Tfh) cells. After secondary stimulation, CX3CR1+ T cells produced both interferon-gamma (IFN-γ) and IL-21. Compared with their CX3CR1- counterparts, CX3CR1+ CD4+ T cells induced plasmablast differentiation from naïve B cells more efficiently (15.0 vs 5.0%) and increased the production of IgG2, IgG3, and IgG4 by B cells. CONCLUSION CX3CR1+ CD4+ T cells characteristically increased in the peripheral blood and the affected tissues and were associated with an increase in the serum IgG4 levels of patients with IgG4-RD. This CD4 subset has a Th1/Tfh-like phenotype and a B cell helper function.

Abstract
OBJECTIVE To clarify the effectiveness and safety of induction therapy with mycophenolate mofetil (MMF) in patients with lupus nephritis (LN). METHODS Patients with LN administered MMF (n = 35) or IVCY (n = 25) plus high-dose corticosteroids between July 2015 and June 2020 were included. MMF was increased from 2 g/day to 3 g/day, with no adverse events (AEs). The primary endpoint was the 6-month renal remission rate. Secondary endpoints were retention rate and AEs. RESULTS There were no significant differences in age, sex, disease duration, renal histological type, SLEDAI, and UPCR between the two groups. Twenty-six patients (74%) continued with MMF therapy, whereas twelve (48%) completed six IVCY courses. The retention rate was significantly higher in the MMF than in the IVCY group (p = 0.048). Twenty-four and fourteen patients in MMF and IVCY groups, respectively, achieved renal remission with insignificant differences. Grade 3 or higher AEs were observed in eight and fourteen patients in the MMF and IVCY groups, respectively (p = 0.014). CONCLUSIONS The efficacy of high-dose MMF was comparable to that of IVCY in Japanese patients with proliferative LN, with fewer AEs and a higher retention rate than IVCY, suggesting the high tolerability of MMF.

Abstract
We herein report a case of a patient with gastric cancer-associated microscopic polyangiitis (MPA) who was treated with combination glucocorticoids and rituximab (RTX) for remission induction and maintenance, and finally to discontinue glucocorticoids without recurrence of gastric cancer or MPA in a year. A 69-year-old man was suspected of having MPA because of fever, high C-reactive protein levels, neuritis, and a high titer of myeloperoxidase-anti-neutrophil cytoplasmic antibody (MPO-ANCA). Upper gastrointestinal endoscopy indicated early-stage gastric cancer, for which he underwent surgery preceded by immunosuppressive therapy for vasculitis. Histopathological images showed vasculitis in the vicinity of the cancerous tissue, suggesting an association between gastric cancer and vasculitis. Postoperatively, fever and inflammatory response improved, but MPO-ANCA increased further and the patient developed alveolar hemorrhage. He resulted in remission with high-dose glucocorticoids and RTX, and he received maintenance therapy with RTX without additional immunosuppressive agents. After 1 year of treatment, he was able to discontinue glucocorticoids without recurrence of gastric cancer or vasculitis. There is no established treatment for malignancy-associated vasculitis other than glucocorticoids. Although more cases need to be accumulated in the future, RTX is expected to be useful in malignancy-associated vasculitis.

Abstract
BACKGROUND The single nucleotide polymorphism (SNP) rs62324212, located in IL21 antisense RNA 1 (IL21-AS1), has been identified as a genetic risk variant associated with systemic lupus erythematosus (SLE). We aimed to probe the characteristics of IL21-AS1 and explore its clinical relevance focusing on T helper subsets and disease activity in patients with SLE. METHODS rs62324212 genotyping was determined using allelic discrimination by quantitative PCR. Gene expression in peripheral blood mononuclear cells and cell surface markers in CD4+ T cells were analyzed using PCR and flow cytometry. The association among IL21-AS1, CD4+ T cell subsets, and SLE disease activity was accessed. RESULTS Ensembl Genome Browser analysis revealed that rs62324212 (C>A) was located in the predicting enhancer region of IL21-AS1. IL21-AS1 was expressed in the nucleus of CD4+ T and B cells, but its expression was decreased in patients with SLE. IL21-AS1 expression was positively correlated with mRNA levels of IL-2 but not IL-21, and it was associated with the proportion of activated T follicular regulatory (Tfr) cells. Furthermore, we observed a significant negative correlation between IL21-AS1 expression and disease activity in patients with SLE (n = 53, p < 0.05). CONCLUSION IL21-AS1 has an effect on disease activity through an involvement of IL-2-mediated activation of Tfr cells in SLE. Thus, targeting the IL21-AS1 may provide therapeutic approaches for SLE.

Abstract
INTRODUCTION Osteonecrosis of the femoral head (ONFH) involves necrosis of bone and bone marrow of the femoral head caused by ischemia with unknown etiology. Previous genetic studies on ONFH failed to produce consistent results, presumably because ONFH has various causes with different genetic backgrounds and the underlying diseases confounded the associations. Steroid-associated ONFH (S-ONFH) accounts for one-half of all ONFH, and systemic lupus erythematosus (SLE) is a representative disease underlying S-ONFH. We performed a genome-wide association study (GWAS) to identify genetic risk factors for S-ONFH in patients with SLE. METHODS We conducted a two-staged GWAS on 636 SLE patients with S-ONFH and 95 588 non-SLE controls. Among the novel loci identified, we determined S-ONFH specific loci by comparing allele frequencies between SLE patients without S-ONFH and non-SLE controls. We also used Korean datasets comprising 148 S-ONFH cases and 37 015 controls to assess overall significance. We evaluated the functional annotations of significant variants by in-silico analyses. RESULTS The Japanese GWAS identified four significant loci together with 12 known SLE susceptibility loci. The four significant variants showed comparable effect sizes on S-ONFH compared with SLE controls and non-SLE controls. Three of the four loci, MIR4293/MIR1265 (OR = 1.99, P-value = 1.1 × 10-9), TRIM49/NAALAD2 (OR = 1.65, P-value = 4.8 × 10-8) and MYO16 (OR = 3.91, P-value = 4.9 × 10-10), showed significant associations in the meta-analysis with Korean datasets. Bioinformatics analyses identified MIR4293, NAALAD2 and MYO16 as candidate causal genes. MIR4293 regulates a PPARG-related adipogenesis pathway relevant to S-ONFH. CONCLUSIONS We identified three novel susceptibility loci for S-ONFH in SLE.

Tono T, Kikuchi H, Sawada T, Takeno M, Nagafuchi H, Kirino Y, Tanaka Y, Yamaoka K, Hirohata S. Clinical Features of Behçet's Disease Patients with Joint Symptoms in Japan: A National Multicenter Study. Mod Rheumatol 2021; 32:1146-1152. [PMID: 34850090 DOI: 10.1093/mr/roab092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 07/12/2021] [Accepted: 10/25/2021] [Indexed: 11/13/2022]
Abstract
OBJECTIVES Approximately 30%-60% of Behçet's disease patients exhibit joint symptoms. The aim of this study was to determine the clinical characteristics of such patients in Japan. METHODS This study retrospectively analyzed 151 Behçet's disease patients with joint symptoms who had been treated at seven cooperative medical institutions from 2007 to 2017. We investigated their clinical characteristics and treatments. RESULTS The most commonly affected joints were the knee, ankle, and proximal interphalangeal joints. Of the cases with pain and swelling, 18 of 293 joints (11 cases) displayed narrowing of the cleft or deformity by Xray analysis. Improvement in their arthritis was observed in 80% of the patients who received steroids as initial treatment; however, the rate of improvement was lower in patients who had received prednisolone (PSL) at <10 mg/day. The recurrence of joint symptoms was significantly less common in the colchicine group than in the PSL group. CONCLUSIONS These results suggest that PSL is effective for remission induction for the treatment of joint symptoms of Behçet's disease, though it may not be effective at low doses. Additionally, colchicine is effective in preventing the recurrence of joint symptoms in Behçet's disease. Furthermore, joint damages like joint space narrowing or with any deformity can often be observed in Behçet's disease patients in Japan.

Abstract
Background Improvements in the treatment of rheumatoid arthritis (RA) have made it possible to achieve treatment goals. It has been reported that both residual synovitis caused by RA and the patients’ subjective symptoms remain even after achieving the treatment goals; however, there are limited reports showing a relationship between them. Furthermore, no studies have evaluated the relationship between patient-reported outcomes (PROs) and subclinical synovitis measured by musculoskeletal ultrasonography (MSUS) in the treatment of RA. This study aimed to investigate residual symptoms and residual synovitis due to remission (REM) or low disease activity (LDA). Methods We performed MSUS on 300 patients with RA who attended our hospital for routine care, and we analysed them cross-sectionally by disease activity. Grayscale (GS) and power Doppler (PD) synovitis was evaluated in 22 bilateral hand joints using MSUS. We first performed univariate and multivariate analysis by dividing the data by disease activity. Next, we analysed each PRO in the obtained MSUS results. Results A multivariate analysis of high disease activity (HDA)/moderate disease activity (MDA) vs. LDA/ REM group identified tender joint count (TJC), pain visual analog scale (VAS) score, and presence or absence of GS score ≥ 2. The one-way analysis of the relationship between the presence or absence of GS score ≥ 2 and each PRO showed a significant difference. In contrast, a multivariate analysis of LDA vs. REM group identified TJC and fatigue VAS score. In REM, PROs alone were relevant, and there was no correlation with MSUS. Conclusion We found that the residual inflammation in the ultrasound images was associated with PROs in the LDA group, but not in the REM group. Trial registration Retrospectively registered.

Abstract
OBJECTIVE This study aimed to understand the role of mTOR in CD8+ cells in the pathogenicity of rheumatoid arthritis (RA) and the changes after treatment with biologic drugs. METHODS Peripheral blood mononuclear cells (PBMCs) were isolated from 17 healthy controls and 86 patients with RA. Phosphorylation of mTOR (p-mTOR) and its clinical relevance were evaluated. The role of mTOR in CD8+ cells was also examined in vitro. RESULTS Patients with RA who had a moderate or high disease activity, were biologic-naïve, and were refractory to MTX were enrolled in this study. The p-mTOR levels in CD8+ cells were higher in patients with RA than in healthy controls, and they positively correlated with the disease activity in such patients. However, after one year of treatment with TNF inhibitors, the p-mTOR levels in CD8+ cells were suppressed and showed a positive correlation with the treatment response, which was not observed in the abatacept-treatment group. In vitro stimulation of CD8+ cells with anti-CD3 and anti-CD28 antibodies induced mTOR phosphorylation and increased the production of granzyme B, GNLY, TNF-α, and IFN-γ but decreased the production of granzyme K. However, on treatment with TNF inhibitors, p-mTOR levels in CD8+ cells and granzyme B production decreased, while granzyme K production increased. The production of GNLY and IFN-γ was not affected by the TNF inhibitors. CONCLUSION These results suggested that mTOR activation in CD8+ cells may be a novel evaluation marker for RA disease activity and a predictive marker of therapeutic response to TNF inhibitors.

Abstract
B cell-targeted therapies have evolved as established therapies for systemic lupus erythematosus (SLE); however, existing approaches still do not thoroughly satisfy clinical requirements due to limited efficacy against memory B cells, autoantibody-producing plasmablasts and disease heterogeneity. To provide a new treatment option for SLE, we created a novel anti-Igβ antibody with enhanced affinity for Fc gamma receptor (FcγR) IIB called ASP2713. ASP2713 cross-reacted with both human and cynomolgus monkey Igβ and showed increased binding affinity for human and monkey FcγRIIB compared to native human IgG1. This binding property allows dominant B cell binding and induction of intrinsic negative feedback signals. In human B cells, ASP2713 significantly and concentration-dependently induced FcγRIIB ITIM phosphorylation, while suppressing proliferation under B cell receptor stimulation. This pharmacological effect was also confirmed in in vitro B cell proliferation and antibody production assays using peripheral B cells isolated from patients with SLE. In a cynomolgus monkey tetanus toxoid-induced antibody production model, ASP2713 almost completely inhibited the increase in antigen-specific antibodies with superior efficacy to rituximab. Additionally, ASP2713 significantly suppressed recall antibody production in response to secondary tetanus toxoid immunization, indicating the memory B cell- and plasmablast-targeting potential of ASP2713. Our results suggest that ASP2713 may have therapeutic potential as a treatment for SLE, where B cells play a pathogenic role.

Abstract
OBJECTIVE To characterise safety of the Janus kinase-1 preferential inhibitor filgotinib in patients with moderately to severely active rheumatoid arthritis. METHODS Data were integrated from seven trials (NCT01668641, NCT01894516, NCT02889796, NCT02873936, NCT02886728, NCT02065700, NCT03025308). Results are from placebo (PBO)-controlled (through week (W)12) and long-term, as-treated (all available data for patients receiving ≥1 dose filgotinib 200 (FIL200) or 100 mg (FIL100) daily) datasets. We calculated exposure-adjusted incidence rates (EAIRs)/100 patient-years filgotinib exposure (100PYE) for treatment-emergent adverse events (TEAEs). RESULTS 3691 patients received filgotinib for 6080.7 PYE (median 1.6, maximum 5.6 years). During the PBO-controlled period, TEAEs, including those of grade ≥3, occurred at comparable rates with filgotinib or PBO; long-term EAIRs of TEAEs grade ≥3 were 6.4 and 7.6/100PYE for FIL200 and FIL100. EAIRs for deaths were 0.6/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 0.5 and 0.3/100PYE for FIL200 and FIL100. EAIRs for serious infection were 3.9, 3.3 and 2.4/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 1.6 and 3.1/100PYE for FIL200 and FIL100. EAIRs for herpes zoster were 0.6, 1.1, and 1.1/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 1.8 and 1.1/100PYE for FIL200 and FIL100. EAIRs for major adverse cardiovascular events were 0, 1.7 and 1.1/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 0.4 and 0.6/100PYE for FIL200 and FIL100. No venous thromboembolism occurred during the PBO-controlled period; long-term EAIRs were 0.2 and 0/100PYE for FIL200 and FIL100. CONCLUSIONS Over a median of 1.6 and maximum of 5.6 years of exposure, safety/tolerability of FIL200 and FIL100 were similar, with a lower incidence of infections with FIL200 among the long-term, as-treated dataset.

Abstract
OBJECTIVE To evaluate the dysfunction of B cell metabolism and its involvement in SLE pathology. METHODS We assessed the expression of metabolic markers of B cells in the peripheral blood of healthy controls (HCs) and SLE patients by using flow cytometry. In vitro, peripheral B cells were isolated from HCs and SLE patients to investigate the metabolic regulation mechanisms involved in their differentiation. RESULTS The expression level of DiOc6 (mitochondrial membrane hyperpolarization) was higher in B cells from SLE patients than in HCs, and correlated to the percentage of plasmablasts in CD19+ cells and with SLEDAI, a disease activity score. Stimulation of CD19+ cells with the Toll-like receptor 9 (TLR9) ligand CpG and IFN-α enhanced glycolysis, oxidative phosphorylation (OXPHOS), DiOc6 expression, and plasmablast differentiation in vitro. In the absence of glutamine, both glycolysis and OXPHOS were reduced, and plasmablast differentiation was suppressed, whereas there was no change in the absence of glucose. As glutamine is an important nutrient for protein synthesis, we further investigated the effect of the glutaminase inhibitor BPTES, which inhibits glutamine degradation, on metabolic regulation. BPTES reduced DiOc6 expression, OXPHOS, reactive oxygen species (ROS) production, ATP production, plasmablast differentiation without affecting glycolysis. Metformin inhibited CpG- and IFN-α-induced glutamine uptake, mitochondrial functions and suppressed plasmablast differentiation. CONCLUSIONS Mitochondrial dysfunction in B cells is associated with plasmablast differentiation and disease activity in SLE. Enhanced mitochondrial functions mediated by glutamine metabolism are important for plasmablast differentiation, which may be a potential therapeutic target for SLE.

Abstract
BACKGROUND Loss-of-function homozygous or compound heterozygous mutations in IL36RN, which encodes interleukin-36 receptor antagonist (IL-36Ra), has been implicated in the pathogenesis of skin disorders. However, the pathogenic role of IL-36Ra in cutaneous ischemia-reperfusion (I/R) injury remains unclear. OBJECTIVES We investigated the role of IL36Ra in cutaneous I/R injury. METHODS We examined I/R injury in Il36rn-/- mice. The area of wounds, numbers of infiltrated cells, apoptotic cells and neutrophil extracellular trap (NET) formation were assessed. The expression levels of various genes were analysed using real-time RT-PCR. The expression of high mobility group box 1 (HMGB1), an endogenous toll-like receptor (TLR) 4 ligand, was confirmed using immunohistology, and serum HMGB1 levels were measured by ELISA. Cytokine production by stimulated cultured J774A.1 and HaCaT cells was examined. RESULTS IL-36Ra deficiency resulted in significantly delayed wound healing and increased neutrophil and macrophage infiltration into the wound tissues. Il36rn-/- mice had increased mRNA expression levels of CXCL1, CXCL2, CCL4, TNF-α, TGF-β, IL-1β, IL-6 and IL-36γ relative to wild-type mice. Apoptosis was identified in keratinocytes by TUNEL assay. HMGB1 expression in the I/R site was decreased in both keratinocytes and adnexal cells, while serum HMGB1 levels were significantly elevated after reperfusion. The mRNA levels of various cytokines, including IL-1β, were elevated in J774A.1 cells through TLR4 signalling by HMGB1 stimulation. In addition, HaCaT cells stimulated with IL-1β showed significantly increased CXCL1, TNF-α, IL-6, IL-36β and IL-36γ mRNA expression. Furthermore, NET formation was increased by IL-36Ra deficiency. Finally, either the blockade of TLR4 signalling by TAK-242 or inhibition of NET formation by Cl-amidine normalized exacerbated I/R injury in Il36rn-/- mice. CONCLUSIONS This study indicated that IL-36Ra deficiency exacerbates cutaneous I/R injury due to excessive inflammatory cell recruitment, NET formation, and excessive cytokine and chemokine production via the TLR4 pathway by HMGB1 released from epidermal apoptotic cells.

Abstract
Abstract
Background
On March 11th, 2011, the Great East Japan Earthquake hit the Tohoku area, and more than 15,000 people lost their lives by the tsunami and earthquake. People who survived natural disasters, terrors, or serious diseases reported long-time psychological distress such as PTSD (Post Traumatic Stress Syndrome) or depression. This study aims to elaborate on factors associated with PTSD post the Great East Japan Earthquake after four years.
Methods
Quantitative and qualitative analysis from a questionnaire survey conducted after four years of the earthquake in 2015. The questionnaires included participants' attributes, IES-R scale to evaluate PTSD, loss of their families by tsunami and earthquake, their own tsunami experience, many relocations after the earthquake, lost job after the earthquake. The open-ended question asked them to write about their challenges in their lives and others.
Results
We received 3465 responses. Among those who responded, the IES-R scale was significantly larger in women (n = 1397) (aOR=1.55, p = 0.001) than men (n = 1966). Higher in those with more their own tsunami experience (aOR=1.35, p = 0.014), in those with lost loved ones (aOR=2.1, p < 0.01), and in those with more economic difficulties (aOR=1.6, p < 0.001). In addition, those with less social connectedness (aOR=1.34, p = 0.017) and forced to live separately with family members after the earthquake(aOR=1.36, p = 0.014) were significantly higher in the scale. From a quality analysis, we observed much psychological distress from participants.
Discussion and Conclusions
In this study, more than half in the PTSD risk group reported that they had never cared for mental pain after the earth quake. We overlook PTSD frequently. However, long-range monitoring and care are necessary for those affected by a significant disaster.
Key messages
PTSD after disasters have been overlooked frequently. A long-range monitoring and care are necessary after a significant disaster.

Abstract
Background the world is facing a novel coronavirus pandemic, and the role of vaccination and vaccination acceptance is playing an important role under current vaccination deployment. Japan's vaccination system has progressed these days greatly; however, the non-mandatory vaccination rate for children such as mumps, influenza is still low due to mothers' hesitancy. Given this circumstance, we conducted a qualitative analysis using text analysis methods for Japanese mothers with children about their hesitancy to vaccinate their children in Japan. Methods We used the data of a questionnaire survey first conducted in 2012, where two hundred and twenty-six mothers participated with an average age of 44.7 years (SD ± 5.02). The questionnaire included open-ended questions, where mothers wrote their opinion freely about vaccination about their children. We conducted text analysis focusing on the keywords of ‘hesitancy' (IBM SPSS Text Analytics for Surveys 4.0). Results The keywords that extracted frequently included; vaccination (n = 160), hesitancy (n = 66), difficulty in access to vaccination (n = 57), knowledge/information scarcity (n = 31), fear for side effect (n = 30), complexity of vaccination schedule (n = 23) and government subsidies (n = 20). The most related keyword with hesitancy was; side effect (n = 20), expensive cost (n = 12), and non-mandatory (n = 10). A keyword of having natural immunity was also closely connected (n = 8). Discussion and Conclusions To ameliorate hesitancy among mothers against vaccination of their children, local government notification and subsidy as mandatory vaccination, providing the correct information about diseases and side effects of vaccinations would work as plus factors. Key messages For pandemic preparedness, it is necessary to research vaccine acceptance among children. This research is to explore vaccine hesitancy among mothers and factors related to their unwillingness.

Abstract
Abstract
Background
Accumulating evidence suggests that high uric acid is strongly associated with obesity and metabolic syndrome and drives the development of non-alcoholic fatty liver disease (NAFLD) and insulin resistance. Although urate transporter-1 (URAT1), which is primarily expressed in the kidney, plays a critical role in the development of hyperuricemia, its pathophysiological implication in NAFLD and insulin resistance remains unclear.
Objectives
We hypothesizes that URAT1 plays an important role in obesity-induced metabolic disorders, and URAT1-selective inhibitor treatment ameliorates systemic insulin resistance, NAFLD and adipose tissue dysfunction using diet-induced obese mice.
Methods
Mice fed a high-fat diet (HFD) for 16 to 18 weeks or a normal-fat diet (NFD) were treated with or without a novel oral URAT1-selective inhibitor (dotinurad [50 mg/kg/day]) for another 4 weeks.
Results
Dotinurad administration significantly ameliorated HFD-induced obesity and insulin resistance. We found that URAT1 was also expressed in the liver and brown adipose tissue (BAT) other than kidney. HFD markedly induced NAFLD, which was characterized by severe hepatic steatosis, as well as the elevation of serum ALT activity and tissue inflammatory cytokine genes (Ccl2 and TNFα), all of which were attenuated by dotinurad. Likewise, HFD significantly increased URAT1 expression in BAT, resulting in the lipid accumulation (whitening of BAT) and increased production of tissue reactive oxygen species, which were reduced by dotinurad via UCP1 activation.
Conclusions
A novel URAT1-selective inhibitor, dotinurad, ameliorates insulin resistance by attenuating hepatic steatosis and promoting rebrowning of lipid-rich BAT in HFD-induced obese mice. URAT1 serves as a key regulator of the pathophysiology of metabolic syndrome, and may be a new therapeutic target for insulin-resistant individuals, particularly those with concomitant NAFLD.

Abstract
Background Oral mucositis (OM) is an unpleasant adverse event in patients receiving chemotherapy. A prospective feasibility study showed that elemental diet (ED), an oral supplement that does not require digestion, may prevent OM. Based on this, we established a central review system for oral cavity assessment by dental oncology specialists blinded to background data. We used this system to elucidate the preventive effect of an ED against OM in patients with esophageal cancer receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy. Patients and methods In this phase III, multicenter, parallel-group, controlled trial, patients consuming a normal diet orally were randomly assigned (1 : 1) to receive two cycles of DCF with (group A) or without (group B) an ED (Elental® 160 g/day). We assessed the incidence of grade ≥2 OM evaluated by two reviewers, changes in body weight, prealbumin, C-reactive protein, and DCF completion rate based on ED compliance. Results Of the 117 patients randomly assigned to treatment, four failed to start treatment and were excluded from the primary analysis; thus, groups A and B comprised 55 and 58 patients, respectively. There were no significant differences in background characteristics. Grade ≥2 OM was observed in eight (15%) and 20 (34%) patients in groups A and B, respectively (P = 0.0141). Changes in body weight and prealbumin during the two DCF cycles were significantly higher in group A than B (P = 0.0022 and 0.0203, respectively). During the first cycle, changes in C-reactive protein were significantly lower in group A than B (P = 0.0338). In group A (receiving ED), the DCF completion rate was 100% in patients with 100% ED compliance and 70% in patients failing ED completion (P = 0.0046). Conclusions The study findings demonstrate that an ED can prevent OM in patients with esophageal cancer receiving chemotherapy. Patients receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy commonly develop oral mucositis (OM). An elemental diet (ED) was able to prevent OM in patients with esophageal cancer receiving DCF. Grade ≥2 OM was observed in 15% of patients receiving the ED versus 34% of those not receiving the ED (P = 0.0141). Body weight was maintained in the ED group, and hematologic toxicities were lower, compared with the non-ED group. The DCF completion rate significantly correlated with ED compliance (P = 0.0046).
