Abstract
Due to optimised treatment strategies and the availability of new therapies during the last decades, formerly devastating chronic inflammatory diseases such as rheumatoid arthritis or systemic sclerosis (SSc) have become less menacing. However, in many patients, even state-of-the-art treatment cannot induce remission. Moreover, the risk for flares strongly increases once anti-inflammatory therapy is tapered or withdrawn, suggesting that underlying pathological processes remain active even in the absence of overt inflammation. It has become evident that tissues have the ability to remember past encounters with pathogens, wounds and other irritants, and to react more strongly and/or persistently to the next occurrence. This priming of the tissue bears a paramount role in defence from microbes, but on the other hand drives inflammatory pathologies (the Dr Jekyll and Mr Hyde aspect of tissue adaptation). Emerging evidence suggests that long-lived tissue-resident cells, such as fibroblasts, macrophages, long-lived plasma cells and tissue-resident memory T cells, determine inflammatory tissue priming in an interplay with infiltrating immune cells of lymphoid and myeloid origin, and with systemically acting factors such as cytokines, extracellular vesicles and antibodies. Here, we review the current state of science on inflammatory tissue priming, focusing on tissue-resident and tissue-occupying cells in arthritis and SSc, and reflect on the most promising treatment options targeting the maladapted tissue response during these diseases.

Th17/IL-17A axis is critical for pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc): SSc patients with high levels of serum IL-17A exhibit reduced lung functions and increased prevalence of PAH. Cytokine 2024; 176:156534. [PMID: 38354516 DOI: 10.1016/j.cyto.2024.156534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 01/15/2024] [Accepted: 01/26/2024] [Indexed: 02/16/2024]
Abstract
BACKGROUND It is thought that systemic sclerosis (SSc) might be a T helper 17 (Th17) cell-driven autoimmune disease. Noticeably, pulmonary arterial hypertension (PAH) is a leading cause of death in patients with SSc. Here, we investigated the association between serum Th17-related cytokines and prevalence of PAH in SSc patients. METHODS This study included 72 SSc patients and 51 healthy controls (HC). We determined clinical manifestations, immunophenotypes including Th subsets in peripheral blood lymphocytes, and the serum levels of interleukin (IL)-17A, IL-17A/F, IL-17B. IL-17C, IL-17D. IL-1β, IL-6, IL-21, IL-22, and IL-23. RESULTS The frequency of Th17 cells was significantly increased in SSc patients compared to HC and was positively correlated with the modified Rodnan skin scores. Furthermore, the serum levels of IL-17A, IL-17D, IL-1β, and IL-6 were significantly increased in SSc patients compared to HC. SSc patients with detected IL-17A showed high levels of IL-17A/F, IL-1β, IL-6, and IL-22, and high frequency of Th17 cells. Interestingly, these patients exhibited the reduced lung functions and increased prevalence of PAH significantly compared to patients with undetected IL-17A. Similarly, SSc patients with detected IL-17A and high IL-6 (≥1.2 pg/mL) exhibited the decreased lung functions and increased prevalence of PAH compared to patients with undetected IL-17A and low IL-6. CONCLUSION We found that SSc patients with high levels of serum IL-17A or both IL-17A and IL-6 show reduced lung functions and high prevalence of PAH. Consequently, it is highly probable that Th17/IL-17A axis is critical for the prevalence of PAH in SSc patients.

Efficacy and safety of tocilizumab in Japanese patients with systemic sclerosis and associated interstitial lung disease: A subgroup analysis of a global, randomised, controlled Phase 3 trial. Mod Rheumatol 2024; 34:530-540. [PMID: 37436828 DOI: 10.1093/mr/road068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 06/15/2023] [Accepted: 06/30/2023] [Indexed: 07/13/2023]
Abstract
OBJECTIVES The aim of this article is to investigate the efficacy and safety of tocilizumab in Japanese patients with systemic sclerosis. METHODS Post hoc subgroup analysis of a global, randomised, controlled trial in patients treated with weekly tocilizumab 162 mg or placebo subcutaneously in a 48-week double-blind period (tocilizumab and placebo groups) followed by tocilizumab for 48 weeks in an open-label extension (continuous-tocilizumab and placebo-tocilizumab groups). RESULTS Among 20 patients, 12 were randomised to tocilizumab (all had interstitial lung disease) and eight were randomised to placebo (six had interstitial lung disease). The modified Rodnan skin score improved in both treatment groups. The mean change in percent-predicted forced vital capacity was 3.3% [95% confidence interval (CI), -2.5 to 9.0] for tocilizumab and -3.8% (95% CI, -9.9 to 2.2) for placebo in the double-blind period and 2.0% (95% CI, -0.7 to 4.6) for continuous-tocilizumab and -1.4% (95% CI, -6.7 to 4.0) for placebo-tocilizumab in the open-label extension. Rates of serious adverse events per 100 patient-years were 19.3 for tocilizumab and 26.8 for placebo in the double-blind period and 0.0 for continuous-tocilizumab and 13.6 for placebo-tocilizumab in the open-label period. CONCLUSIONS The efficacy and safety of tocilizumab in patients with systemic sclerosis were consistent between the Japanese subpopulation and the global trial population.

Abstract
Cyclophosphamide (CYC) has been a gold standard of treatment for severe progressive Systemic Sclerosis (SSc), especially in patients with concomitant interstitial lung disease (ILD). This approach was based on results of several interventional studies, including randomized control trials, which mainly addressed SSc-ILD as a primary end point and skin involvement as a second one. The use of CYC is time-limited due to significant adverse events. More recently, other immunosuppressive and biological agents showed efficacy but better safety profile in patients with SSc and SSc-ILD. With regards to other end-points, post-hoc analyses, systematic reviews and metalysis showed that CYC had limited influence on patients' quality of life, event-free survival and mortality. Comprehensive patient's stratification according to a molecular, cellular and phenotypic pattern may help in choosing of personalized medicine with more ambitious treatment effect and should be the future direction. According to the above available data and even if scientific evidence may be missing, experts' opinion has changed the attitude to CYC as an anchor drug in the management of severe SSc. Indeed, CYC has been pushed to the second and even third treatment option after mycophenolate mofetil, tocilizumab or rituximab. This position became obvious during debate on this topic at CORA meeting 2023.

Abstract
Systemic sclerosis (SSc) is a complex autoimmune disease characterized by vascular damage, vasoinstability, and decreased perfusion with ischemia, inflammation, and exuberant fibrosis of the skin and internal organs. Biomarkers are analytic indicators of the biological and disease processes within an individual that can be accurately and reproducibly measured. The field of biomarkers in SSc is complex as recent studies have implicated at least 240 pathways and dysregulated proteins in SSc pathogenesis. Anti-nuclear antibodies (ANA) are classical biomarkers with well-described clinical classifications and are present in more than 90% of SSc patients and include anti-centromere, anti-Th/To, anti-RNA polymerase III, and anti-topoisomerase I antibodies. Transforming growth factor-β (TGF-β) is central to the fibrotic process of SSc and is intimately intertwined with other biomarkers. Tyrosine kinases, interferon-1 signaling, IL-6 signaling, endogenous thrombin, peroxisome proliferator-activated receptors (PPARs), lysophosphatidic acid receptors, and amino acid metabolites are new biomarkers with the potential for developing new therapeutic agents. Other biomarkers implicated in SSc-ILD include signal transducer and activator of transcription 4 (STAT4), CD226 (DNAX accessory molecule 1), interferon regulatory factor 5 (IRF5), interleukin-1 receptor-associated kinase-1 (IRAK1), connective tissue growth factor (CTGF), pyrin domain containing 1 (NLRP1), T-cell surface glycoprotein zeta chain (CD3ζ) or CD247, the NLR family, SP-D (surfactant protein), KL-6, leucine-rich α2-glycoprotein-1 (LRG1), CCL19, genetic factors including DRB1 alleles, the interleukins (IL-1, IL-4, IL-6, IL-8, IL-10 IL-13, IL-16, IL-17, IL-18, IL-22, IL-32, and IL-35), the chemokines CCL (2,3,5,13,20,21,23), CXC (8,9,10,11,16), CX3CL1 (fractalkine), and GDF15. Adiponectin (an indicator of PPAR activation) and maresin 1 are reduced in SSc patients. A new trend has been the use of biomarker panels with combined complex multifactor analysis, machine learning, and artificial intelligence to determine disease activity and response to therapy. The present review is an update of the various biomarker molecules, pathways, and receptors involved in the pathology of SSc.

Use of Biologics for Systemic Sclerosis and Systemic Sclerosis-Associated Interstitial Lung Disease: Information from a Japanese Hospital Claims Database. Mod Rheumatol 2022; 33:525-532. [PMID: 35652700 DOI: 10.1093/mr/roac055] [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: 05/12/2022] [Revised: 05/22/2022] [Accepted: 05/23/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVES Limited information is available on the use of biologics in patients with systemic sclerosis (SSc) or SSc-associated interstitial lung disease (SSc-ILD) in Japan. The types of biologics, treatment duration, treatment prior to biologics, concomitant treatment, and characteristics of patients receiving biologics were investigated. METHOD We used a Japanese hospital claims database provided by Medical Data Vision Co. (2008-2021). RESULTS In the database, 1,186 of 34,207 SSc patients (3.5%) and 620 of 12,303 SSc-ILD patients (5.0%) received anti-interleukin-6 (anti-IL-6) drugs, anti-tumor necrosis factor (anti-TNF) drugs, abatacept, or rituximab. The most common were anti-IL-6 drugs (used in 35.5% of SSc patients and 38.5% of SSc-ILD patients [tocilizumab, 34.5% and 36.6%]), followed by anti-TNF drugs (31.3% and 26.5% [etanercept, 10.5% and 9.0%; others, <8%]), abatacept (17.5% and 20.6%), and rituximab (15.7% and 14.4%). Among SSc and SSc-ILD patients treated with anti-IL-6 drugs, anti-TNF drugs, or abatacept, the most common immunosuppressive drugs prior to initiation of biologics were methotrexate and tacrolimus. Approximately half of patients receiving anti-IL-6 drugs, anti-TNF drugs, or abatacept continued treatment beyond 1 year. CONCLUSIONS Our study indicates that off-label biologics have been used in a certain number of SSc or SSc-ILD patients in Japan, with tocilizumab the most common.
