Abstract
Collagen vascular disease is a heterogeneous group of autoimmune diseases that affect multiple organ systems. Sjögren syndrome, dermatomyositis, scleroderma, systemic lupus erythematosus, and sarcoidosis are collagen vascular diseases that often present with characteristic cutaneous manifestations. Although less known, various ocular manifestations that affect both external and internal structures of the eye can also be seen in these conditions. Multidisciplinary management between dermatologists and ophthalmologists is essential in the early diagnosis and management of collagen vascular diseases affecting both the skin and eye. In part II of our series, we discuss the ocular manifestations, diagnosis, and therapeutic options of dermatomyositis, scleroderma, and sarcoidosis.

Differentially expressed genes in systemic sclerosis: Towards predictive medicine with new molecular tools for clinicians. Autoimmun Rev 2023; 22:103314.

Abstract
Systemic sclerosis (SSc) is a rare and chronic autoimmune disease characterized by a pathogenic triad of immune dysregulation, vasculopathy, and progressive fibrosis. Clinical tools commonly used to assess patients, such as the modified Rodnan skin score, difference between limited or diffuse forms of skin involvement, presence of lung, heart or kidney involvement, or of various autoantibodies, are important prognostic factors, but still fail to reflect the large heterogeneity of the disease. SSc treatment options are diverse, ranging from conventional drugs to autologous hematopoietic stem cell transplantation, and predicting response is challenging. Genome-wide technologies, such as high throughput microarray analyses and RNA sequencing, allow accurate, unbiased, and broad assessment of alterations in expression levels of multiple genes. In recent years, many studies have shown robust changes in the gene expression profiles of SSc patients compared to healthy controls, mainly in skin tissues and peripheral blood cells. The objective analysis of molecular patterns in SSc is a powerful tool that can further classify SSc patients with similar clinical phenotypes and help predict response to therapy. In this review, we describe the journey from the first discovery of differentially expressed genes to the identification of enriched pathways and intrinsic subsets identified in SSc, using machine learning algorithms. Finally, we discuss the use of these new tools to predict the efficacy of various treatments, including stem cell transplantation. We suggest that the use of RNA gene expression-based classifications according to molecular subsets may bring us one step closer to precision medicine in Systemic Sclerosis.

Abstract
Systemic sclerosis (SSc), a rare, chronic progressive systemic autoimmune disease of unknown etiology, is characterized by autoimmunity, tissue fibrosis, and obliterative vasculopathy. SSc can affect all major organs including the skin, blood vessels, lung, heart, kidneys, and gastrointestinal tract. Our understanding of its pathogenesis has increased over the past few decades, leading to improved diagnosis and treatment. However, the mortality rate of SSc remains considerable, mainly due to cardiopulmonary causes. A growing body of evidence suggests that geographical, regional, and ethnic differences could affect the epidemiology, clinical characteristics and prognosis of SSc. Although Korean data of this issue are lacking, a considerable amount of research has been published by many Korean researchers. To establish treatment strategies for Korean patients, extensive Korean research data are needed. This review summarizes the prevalence, incidence, mortality, and clinical and laboratory manifestations of Korean patients with SSc and discusses the current trends in evidence-based treatment and recommendations.

Abstract
Diffuse cutaneous systemic sclerosis (dcSSc) is associated with high mortality resulting from early internal-organ involvement. Clinicians therefore tend to focus on early diagnosis and treatment of potentially life-threatening cardiorespiratory and renal disease. However, the rapidly progressive painful, itchy skin tightening that characterizes dcSSc is the symptom that has the greatest effect on patients' quality of life, and there is currently no effective disease-modifying treatment for it. Considerable advances have been made in predicting the extent and rate of skin-disease progression (which vary between patients), including the development of techniques such as molecular analysis of skin biopsy samples. Risk stratification for progressive skin disease is especially relevant now that haematopoietic stem-cell transplantation is a treatment option, because stratification will inform the balance of risk versus benefit for each patient. Measurement of skin disease is a major challenge. Results from clinical trials have highlighted limitations of the modified Rodnan skin score (the current gold standard). Alternative patient-reported and other potential outcome measures have been and are being developed. Patients with early dcSSc should be referred to specialist centres to ensure best-practice management, including the management of their skin disease, and to maximize opportunities for inclusion in clinical trials.

Abstract
Juvenile-onset systemic sclerosis (jSSc) is a complex multisystem inflammatory-driven disease of fibrosis, requiring multifaceted treatment including pharmacologic therapy, supportive care, and lifestyle modification. Most regimens are adapted from adult SSc treatment given the rarity of the disease. Landmark trials over the past decade in adult SSc have led to 2 Food and Drug Administration-approved therapies for SSc-associated interstitial lung disease, and several ongoing trials of other biological agents are underway. Resetting the immune system with autologous stem cell transplant to halt this disease earlier in its course, especially in pediatric onset where disease burden can accumulate, is on the horizon.

Abstract
OBJECTIVES To investigate safety and efficacy of MMF in patients with severe or MTX-refractory juvenile localized scleroderma. METHODS Consecutive juvenile localized scleroderma patients undergoing systemic treatment were included in a retrospective longitudinal study. Patients treated with MMF because they were refractory or intolerant to MTX (MMF-group) were compared with responders to MTX (MTX-group). Disease activity was assessed by Localized Scleroderma Cutaneous Assessment Tool and thermography. Disease course was established on the number of relapses and treatment changes. Relapse-free survival was examined by Kaplan-Meier analysis. RESULTS MMF and MTX groups included 22 and 47 patients, respectively. No significant difference in demographics, follow-up duration and treatment before diagnosis was observed between groups. The most represented clinical subtypes in the MMF-group were pansclerotic morphea and mixed subtype (P = 0.008 and P = 0.029, respectively), and linear scleroderma of the face in the MTX-group (P = 0.048). MMF was started because of MTX resistance (18 patients), relapse during MTX tapering/withdrawal (3 patients) and anaphylaxis to MTX (1 patient). After mean 9.4 years of follow-up, 90.9% of patients on MMF and 100% of those on MTX had inactive disease. No significant difference in relapse-free survival between the groups was found (P = 0.066, log-rank test), although MMF likely induced more persistent remission. MMF was well tolerated and combination of MMF and MTX did not increase its efficacy. CONCLUSION The present study adds strong evidence on the efficacy and tolerance of MMF in severe and/or MTX-refractory juvenile localized scleroderma. Further controlled studies are needed to prove its efficacy as first line treatment.

Abstract
Patients with connective tissue diseases have been shown to be at higher risk for complications after surgery. In this report, we describe a case of a patient with long-standing, stable systemic sclerosis (SS), diagnosed approximately 28 years ago, who underwent nipple-sparing mastectomy and immediate reconstruction with prepectoral tissue-expander placement. She subsequently had uneventful implant-based reconstruction with adjunctive fat grafting. To our knowledge, this is the first reported case of implant-based prepectoral reconstruction after mastectomy in a patient with SS.

Abstract
OBJECTIVE To explore pharmacokinetic/pharmacodynamic relationship between mycophenolic acid area under the curve and clinical response at 1 year on skin involvement or interstitial lung disease in patients with systemic sclerosis. METHOD Retrospective, monocentric study based on French Scleroderma Database in patients receiving mycophenolate mofetil who experienced a limited sampling strategy to estimate individual mycophenolic acid area under the curve plus two pulmonary function tests and skin evaluation after 1 month and 1 year. Efficacy criterions were variations of modified Rodnan skin score, forced vital capacity, and diffusing lung capacity for carbon monoxide at 1 year. RESULTS We included 52 patients; mean age was 49 years (range 17-79), and 36 (69%) were females. Fifty patients (96%) had skin sclerosis, 39 (75%) had diffuse skin involvement with a median modified Rodnan skin score of 14 (0-38). Thirty-eight (76%) had interstitial lung disease, with median forced vital capacity and diffusing lung capacity for carbon monoxide of 81% (37-127) and 56% (28-103) from predicted values, respectively. Twenty-five (51%) patients had pulmonary fibrosis. Mycophenolate mofetil was given for 10 months (0-173) at a median dose of 2000 mg/day (500-3000). In the entire population, no relationship was found between area under the curve and modified Rodnan skin score (p = 0.085), forced vital capacity (p = 0.80), or diffusing lung capacity for carbon monoxide (p = 0.72) variations at 1 year. CONCLUSION In this retrospective study, we failed to document any relationship between mycophenolic acid area under the curve and skin involvement or interstitial lung disease evolution. Routine monitoring of mycophenolic acid in systemic sclerosis patients treated with mycophenolate mofetil cannot be recommended based on our results.

Abstract
Mycophenolate mofetil (MMF) is an antimetabolite with a potent inhibitory effect on proliferation of T and B lymphocytes used since the early 1990s for the prevention of acute allograft rejection after organ transplant. MMF is also widely used for the treatment of a variety of rheumatic diseases (RDs) and their pulmonary involvement. Interstitial lung disease (ILD) is a heterogeneous group of progressive fibrotic diseases of the lung, which is often secondary to RD and represents a major cause of morbidity and mortality. MMF is considered the main alternative to cyclophosphamide as a first-line agent to treat RD-related ILD or as possible maintenance therapy after cyclophosphamide, with a lower rate of side-effects. However, as for other immunosuppressive agents, the use of MMF in RD-ILD is supported by poor scientific evidence. In this narrative review, we describe the available data and recent advances on the effectiveness and safety of MMF for the treatment of ILD related to RD, including rheumatoid arthritis, systemic sclerosis, primary Sjögren syndrome, systemic lupus erythematosus, idiopathic inflammatory myopathies, undifferentiated connective tissue disease, interstitial pneumonia with autoimmune features and antineutrophil cytoplasmic antibody-associated vasculitis.

Abstract
PURPOSE Rituximab is widely prescribed to treat systemic sclerosis (SSc) by the depletion of pathogenic B cells. Nonetheless, the clinical benefit of Rituximab in SSc remains contentious. This meta-analysis was conducted to systematically evaluate the safety and efficacy profile of Rituximab in SSc patients. PATIENTS AND METHODS We performed a systematic online query in PubMed, Cochrane, and Web of Science. The available studies on the use of Rituximab in SSc patients were comprehensively reviewed and investigated. RESULTS In total, 14 studies, including 597 participants, were analyzed. Pooled results showed the long-term improvement in the modified Rodnan skin score (mRSS) for skin function (ΔmRSS: 7.00 at 6 months, 9.70 at 12 months, and 10.93 at 24 months), while forced vital capacity (FVC) (ΔFVC: -0.69 at 6 months, -2.62 at 12 months, and -0.67 at 24 months) and diffusing capacity of the lungs for carbon monoxide (DLCO) (ΔDLCO: -2.39 at 6 months, -3.28 at 12 months, and -0.79 at 24 months) for lung function remained stable in SSc patients after Rituximab treatment. The rate of Rituximab-related adverse events was 12% in the pooled results. CONCLUSION The pooled results of this meta-analysis indicated that Rituximab is well tolerated, and it is able to improve cutaneous function and stabilize pulmonary function in SSc patients.

Abstract
BACKGROUND Epstein Barr virus (EBV)-associated primary central nervous system lymphoma (ePCNSL) is increasingly recognized in immunocompromised subjects, including patients receiving systemic immunosuppressive therapy. Here, we report the first case of primary CNS lymphoma associated with EBV in a patient with diffuse cutaneous systemic sclerosis (dcSSc) receiving long-term mycophenolate mofetil (MMF). CASE REPORT A 51-year-old female with dcSSc had been on MMF 2 grams daily, which was initiated for a rapidly rising modified Rodnan skin score (mRSS), severe pruritus, and progressive joint contractures. She had an impressive response to this therapy with a significant decrease in her mRSS. Her condition remained stable for the next five years, after which she developed worsening headaches for 2-3 weeks, associated with dizziness, gait instability, and left homonymous hemianopia. MRI scan of the brain revealed a solitary 2.4cm peripherally enhancing right parietal lobe mass. Excised tissue from the right parietal lobe mass showed EBV-associated diffuse large B cell lymphoma. She received four cycles of chemotherapy (high dose methotrexate and rituximab). Currently, her condition is being monitored. Her left homonymous hemianopia persists. CONCLUSION Because of a favorable toxicity profile, MMF is increasingly being used as long-term immunomodulatory therapy for a wide variety of autoimmune disorders. Nevertheless, patients on long-term MMF should still undergo regular CNS surveillance, not only for opportunistic infections but also for opportunistic malignancies such as PCNSL. Progressive focal or non-focal neurological deficits should always raise the alarm. Prompt evaluation and management can prevent irreversible neurological sequelae.

Abstract
The purine nucleotides ATP and GTP are essential precursors to DNA and RNA synthesis and fundamental for energy metabolism. Although de novo purine nucleotide biosynthesis is increased in highly proliferating cells, such as malignant tumors, it is not clear if this is merely a secondary manifestation of increased cell proliferation. Suggestive of a direct causative effect includes evidence that, in some cancer types, the rate-limiting enzyme in de novo GTP biosynthesis, inosine monophosphate dehydrogenase (IMPDH), is upregulated and that the IMPDH inhibitor, mycophenolic acid (MPA), possesses anti-tumor activity. However, historically, enthusiasm for employing IMPDH inhibitors in cancer treatment has been mitigated by their adverse effects at high treatment doses and variable response. Recent advances in our understanding of the mechanistic role of IMPDH in tumorigenesis and cancer progression, as well as the development of IMPDH inhibitors with selective actions on GTP synthesis, have prompted a reappraisal of targeting this enzyme for anti-cancer treatment. In this review, we summarize the history of IMPDH inhibitors, the development of new inhibitors as anti-cancer drugs, and future directions and strategies to overcome existing challenges.

Recurrence of progressive skin involvement following discontinuation or dose reduction of Mycophenolate Mofetil treatment in patients with diffuse Systemic Sclerosis. Semin Arthritis Rheum 2019; 50:135-139.

Abstract
BACKGROUND Rapidly progressive diffuse cutaneous Systemic Sclerosis (rp-dcSSc) is associated with severe internal organ involvement and high mortality. Mycophenolate Mofetil (MMF) has been shown to halt the progression of rp-dcSSc cutaneous and pulmonary involvement in observational and randomized controlled trials, respectively. However, optimal MMF therapy duration has not been established. Here, we describe the clinical evolution of rp-dcSSc patients successfully treated with MMF following MMF therapy discontinuation or dose reduction. METHODS Twenty-five patients with recent-onset (< 24 mo) rp-dcSSc received MMF as the only SSc disease-modifying therapy. Following MMF discontinuation or dose reduction to or below 1000 mg/day after an average of two years, the Modified Rodnan skin score (mRSS) and Pulmonary function tests (PFT) were serially evaluated for additional 5 years. MMF therapy was re-instituted if the mRSS increased by greater than 20% or if restrictive lung disease developed. RESULTS From nineteen patients serially evaluated following MMF discontinuation or dose reduction, five patients (26.3%) developed recurrence of rapid skin involvement with an average of 35.9% increase in mRSS from 7.8 to 10.6 points requiring MMF re-institution. Two of these patients also presented worsening respiratory symptoms and reduction of lung volumes in PFTs. Following MMF resumption, mRSS returned to baseline or stabilized and PFTs improved or stabilized. All these patients were maintained on high dose long term MMF treatment. CONCLUSION Recurrence of severe skin involvement occurred in 26.3% of patients with rp-dcSSc following MMF discontinuation or dose reduction, requiring prompt MMF therapy resumption. These findings confirm the therapeutic benefit of MMF in rp-dcSSc and suggest that MMF treatment should be maintained for longer than 2 years.

Abstract
Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by progressive destruction of the intrahepatic bile ducts, leading to cholestasis. PBC is known to have both hepatic and extrahepatic manifestations. Extrahepatic manifestations are seen in up to 73% of patients with PBC, with the most common being Sjogren’s syndrome, thyroid dysfunction and systemic sclerosis. It is thought that patients with PBC are at increased risk of developing these extrahepatic manifestations, almost all of which are autoimmune, because patients with autoimmune disease are at higher risk of developing another autoimmune condition. Due to the high prevalence of extrahepatic diseases in patients with PBC, it is important to complete a thorough medical history at the time of diagnosis. Prompt recognition of extrahepatic disease can lead to improved patient outcomes and quality of life. The following review summarizes the most common extrahepatic conditions associated with PBC.

Abstract
INTRODUCTION Systemic sclerosis (SSc) is a rare autoimmune connective tissue disease characterized by vascular dysfunction, fibrosis, inflammation and autoantibodies. The pathophysiology of SSc is not completely understood, and many patients acquire organ or tissue damage despite advances in treatment. Current treatments target affected organs with modest improvements. Areas covered: This review evaluates several treatment strategies for SSc based on involved organs including skin, pulmonary, cardiac, renal, musculoskeletal, and gastrointestinal. Currently, pulmonary hypertension and interstitial lung disease are the primary causes of increased mortality. We will outline an approach to treatment of SSc based on disease manifestations and current evidence. Expert commentary: This complex disease is currently treated with therapies developed for similar indications such as for vascular manifestations of SSc using idiopathic pulmonary arterial hypertension treatments. Future directions in this field may include combination and maintenance therapy that is currently used in other autoimmune diseases, and tailoring these treatments according to the patients' phenotype. This will hopefully increase the efficacy of available treatments and decrease mortality from SSc.

Abstract
OBJECTIVE To assess the efficacy of mycophenolate mofetil (MMF) and cyclophosphamide (CYC) on modified Rodnan skin score (MRSS) in participants enrolled in the Scleroderma Lung Study (SLS) I and II. METHODS SLS I participants received daily oral CYC or matching placebo for 1 year, whereas SLS II participants received daily MMF for 2 years or daily oral CYC for 1 year followed by placebo for second year. We assessed the impact of MMF and CYC on the MRSS in SLS II over a 24-month period. We also compared the change in MRSS in patients with diffuse cutaneous systemic sclerosis (dcSSc) assigned to CYC and MMF in SLS II and SLS I versus placebo in SLS I over a 24-month period using a linear mixed model. RESULTS In SLS II, the baseline mean ± SD MRSS was 14.0 ± 10.6 units for CYC and 15.3 ± 10.4 units for MMF; 58.5% were classified as dcSSc. CYC and MMF were associated with statistically significant improvements in MRSS from baseline over the period of 24 months in dcSSc (P < 0.05 at each time point), but there were no differences between the 2 groups. In the dcSSc subgroup, the change in MRSS from baseline to all 6-month visits was similar in SLS II groups (MMF, CYC, pooled cohort [MMF + CYC]) and in the SLS I CYC group and showed statistically significant improvements compared to SLS I placebo at 12, 18, and 24 months (P < 0.05). CONCLUSION In SLS II, MMF and CYC treatment resulted in improvements in MRSS in patients with dcSSc over 24 months. In addition, MMF and CYC treatment resulted in statistically significant improvements in MRSS in patients with dcSSc when compared with the SLS I placebo group.

Abstract
Systemic sclerosis, also called scleroderma, is an immune-mediated rheumatic disease that is characterised by fibrosis of the skin and internal organs and vasculopathy. Although systemic sclerosis is uncommon, it has a high morbidity and mortality. Improved understanding of systemic sclerosis has allowed better management of the disease, including improved classification and more systematic assessment and follow-up. Additionally, treatments for specific complications have emerged and a growing evidence base supports the use of immune suppression for the treatment of skin and lung fibrosis. Some manifestations of the disease, such as scleroderma renal crisis, pulmonary arterial hypertension, digital ulceration, and gastro-oesophageal reflux, are now treatable. However, the burden of non-lethal complications associated with systemic sclerosis is substantial and is likely to become more of a challenge. Here, we review the clinical features of systemic sclerosis and describe the best practice approaches for its management. Furthermore, we identify future areas for development.

Abstract
BACKGROUND The impact of connective tissue disease (CTD) on outcomes following breast surgery and reconstruction is unknown. The purpose of this study was to evaluate the effect of both CTDs and systemic immunomodulatory therapy on outcomes following breast surgery and reconstruction. METHODS A retrospective review was performed of all patients from 2005 to 2010 with an active CTD who underwent breast surgery with or without reconstruction. Surgical events were assigned to 1 of 4 groups: ablative surgery alone, autologous reconstruction, implant reconstruction, and revision surgery. Logistic regression was utilized to examine the relationship between complications and type of surgery, CTD diagnosis, and immunomodulatory therapy. Four non-CTD control groups were then compiled for outcome comparison. The a priori P-value was set at P < 0.05, and all tests were 2 sided. RESULTS Thirty-three patients with CTD underwent112 procedures. Diagnoses included psoriasis/psoriatic arthritis (n = 12), rheumatoid arthritis (n = 10), lupus (n = 4), scleroderma (n = 3), Sjogren syndrome (n = 2), mixed CTD (n = 1), and seronegative polyarthritis (n = 1). Nineteen of 33 (58%) patients who received systemic treatment for CTD in the perioperative period were less likely to experience a minor complication compared with those without treatment (odds ratio= 0.69; P = 0.019). There were no differences in postoperative complications in patients with CTD compared with control groups. CONCLUSIONS Ablative breast surgery and reconstruction among patients with CTDs can be performed safely with low perioperative complication rates. Patients receiving systemic therapy, and continuing their regimens perioperatively, experience complication rates similar to those not requiring therapy.

Abstract
Systemic sclerosis (SSc) is a generalized connective tissue disorder characterized by microvascular damage, autoimmunity, and excessive fibrosis of the skin and various internal organs. Regardless of the recent progress in medicine, no radical therapy for SSc has been developed, and the risk of mortality remains high. Therefore, diagnosis in the early disease stage, risk stratification for the development of serious organ involvement and therapeutic intervention with disease-modifying drugs can reduce the maximum degree of fibrosis, leading to improved long-term survival. Recently, new criteria for very early diagnosis of SSc have been proposed, which are expected to be useful for regularly following up patients with very early SSc, regardless of the absence of skin sclerosis, and for detecting the development of internal organ involvement as early as possible. At present, several immunosuppressants, including methotrexate, corticosteroids and cyclophosphamide, are being used for the treatment of fibrosis. Furthermore, mycophenolate mofetil, i.v. immunoglobulins, B-cell depletion, anti-interleukin-6 receptor antibody, autologous hematopoietic stem cell transplantation, rapamycin, pirfenidone and imatinib mesylate are potential candidates for the treatment of SSc, although their efficacy has not been validated. Moreover, targeting transforming growth factor-1 and its signaling pathway or modulating the imbalance between T-helper 1 and 2 immune responses are also attractive therapeutic options. This review describes recent advances in the strategy for treatment of fibrosis in SSc and future perspectives.

Abstract
Musculoskeletal (MSK) symptoms in patients with systemic sclerosis (SSc) include articular involvement (arthralgia, synovitis, contractures), which is often an early phenomenon and significantly contributes to the disability. Predominantly the hands are affected. Consensus in outcome measures of articular involvement is missing. Health Assessment Questionnaire Disability Index (HAQ-DI), Cochin Hand Function Scale (CHFS), Hand Mobility Index in Scleroderma (HAMIS), and Disease Activity Score of 28 Joints (DAS28) may be used for the assessment of different aspects of joint involvement. There is an unmet need for therapies confirmed by randomized controlled clinical trials (RCTs) to treat both synovitis and non-inflammatory joint involvement. The few rehabilitation studies that have been conducted have shown some promising efficacy. Muscle involvement may be an early symptom. The presence of clinically meaningful muscle involvement often heralds an unfavourable prognosis. The histology of muscle biopsy shows a variable picture including inflammation and necrosis. Besides, signs of acute neurogenic atrophy have been recently described as a previously underestimated contributor to muscle weakness. Similar to articular involvement, the lack of classification criteria on inflammatory and non-inflammatory SSc-associated myopathies, and the lack of validated core set of outcome measures makes it difficult to perform RCTs. The SSc-specific fibrinous tenosynovitis (tendon-friction rubs /TFRs/) is a frequent finding in SSc. Patients with TFR are at increased risk of developing renal, vascular, cardiac and gastrointestinal involvement and have reduced survival rates. Changes of fibrinous tenosynovitis can be objectively detected by ultrasound and may be used as an outcome measure in the treatment of MSK involvement.

Abstract
Autoimmune connective tissue diseases (CTDs) have a propensity to affect multiple organ systems as well as physical function, quality of life, and survival. Their clinical heterogeneity, multisystem involvement, and low worldwide prevalence present challenges for researchers to establish a study design to help better understand the course and outcomes of CTDs. Systemic sclerosis (SSc) is a notable example of a CTD, wherein longitudinal cohort studies (LCS) have enabled us to elucidate disease manifestations, disease course, and risk and prognostic factors for clinically important outcomes, by embedding research in clinical practice. Nevertheless, further efforts are needed to better understand SSc especially with regard to recognizing organ involvement early, developing new therapies, optimizing the use of existing therapies, and defining treatment targets. The heterogeneous multi-organ nature of SSc would lend itself well to a structured model of care, wherein step-up treatment algorithms are used with the goal of attaining a prespecified treatment target. In this chapter, we discuss the rationale for a structured treatment approach in SSc and propose possible treatment algorithms for three of the more common disease manifestations, namely skin involvement, digital ulcers and gastrointestinal tract involvement. We discuss possible strategies for evaluating and implementing these algorithms in the setting of LCS. We conclude by presenting a research agenda for the development of structured models of care in SSc.

Abstract
Systemic sclerosis (SSc or scleroderma) is a progressive and highly debilitating autoimmune disorder characterized by inflammation, vasculopathy, and extensive fibrosis. SSc is highly heterogeneous in its clinical presentation, extent and severity of skin and internal organ involvement, and clinical course and has the highest fatality rate among connective tissue diseases. While clinical outcomes have improved in recent years, no current therapy is able to reverse or slow the natural progression of SSc, a reflection of its complex pathogenesis. Although activation of the immune system has long been recognized, the mechanisms responsible for the initiation of autoimmunity and the role of immune effector pathways in the pathogenesis of SSc remain incompletely understood. This review summarizes recent progress in disease pathogenesis with particular focus on the immunopathogenetic mechanisms of SSc.

Abstract
Systemic sclerosis (SSc) is a chronic immune disorder of unknown origin, dominated by excessive fibrosis responsible for cutaneous and pulmonary fibrosis, and by vascular endothelial dysfunction at the origin of skin ischemia, renal and pulmonary artery lesions. Renal and pulmonary complications are mainly responsible for the severity of the disease. Recent advances led to a better understanding of pathological mechanisms and a more accurate classification of patients according to clinical and biological (auto-antibodies) phenotype. Recent trials provided interesting data on different therapeutic strategies, depending on organ involvement. These data are of particular importance in such disease, still characterized by increased mortality and morbidity rates. In this review, we aim to synthetize recent advances in diagnosis and prognosis leading to better classification of SSc patients, and in therapeutic management.

RECENT FINDINGS Our systematic review identifies randomized controlled trials, meta-analyses, systematic reviews, case series, and observational studies which support organ-based therapy with known immunosuppressive agents, novel agents, and hematopoietic stem cell transplantation, and also includes nonpharmacologic therapies improving visceral and physical function. SUMMARY SSc is an orphan autoimmune disorder with significant morbidity and mortality. Although there has been significant progress over the years in therapeutic options for SSc, the mainstays of treatment are organ-based and primarily symptom management. Our systematic review of the last 4 years of treatment emphasizes known treatment strategies already in practice, but also identifies new therapeutic approaches with additional biologic agents and hematopoietic stem cell transplantation.

Abstract
INTRODUCTION Systemic Sclerosis (SSc) is a systemic autoimmune disease characterized by severe and often progressive cutaneous, pulmonary, cardiac and gastrointestinal tract fibrosis, cellular and humoral immunologic alterations, and pronounced fibroproliferative vasculopathy. There is no effective SSc disease modifying therapy. Patients with rapidly progressive SSc have poor prognosis with frequent disability and very high mortality. AREAS COVERED This paper reviews currently available therapeutic approaches for rapidly progressive SSc and discuss novel drugs under study for SSc disease modification. EXPERT OPINION The extent, severity, and rate of progression of SSc skin and internal organ involvement determines the optimal therapeutic interventions for SSc. Cyclophosphamide for progressive SSc-associated interstitial lung disease and mycophenolate for rapidly progressive cutaneous involvement have shown effectiveness. Methotrexate has been used for less severe skin progression and for patients unable to tolerate mycophenolate. Rituximab was shown to induce improvement in SSc-cutaneous and lung involvement. Autologous bone marrow transplantation is reserved for selected cases in whom poor survival risk outweighs the high mortality rate of the procedure. Novel agents capable of modulating fibrotic and inflammatory pathways involved in SSc pathogenesis, including tocilizumab, pirfenidone, tyrosine kinase inhibitors, lipid lysophosphatidic acid 1, and NOX4 inhibitors are currently under development for the treatment of rapidly progressive SSc.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune disease characterized by autoantibody production, small-vessel vasculopathy, and skin and other organ fibrosis. The disease is clinically heterogeneous with most patients having some degree of skin sclerosis with varying organ system involvement. Early disease can be difficult to diagnose, especially with minimal skin sclerosis and absence of anti-nuclear antibody (ANA) positivity; however, studies have demonstrated early diagnosis is important as early treatment could potentially lead to better outcomes. New classification criteria have recently been published that have higher sensitivity for detecting early disease thus allowing for a broader spectrum of patients to be represented in clinical trials. Treatment guidelines have been published based on a limited number of randomized-controlled clinical trials; however, there are ongoing phase II and III clinical trials with novel agents that are promising and will change the treatment landscape over the next decade.

Abstract
Although scleroderma-associated interstitial lung disease (SSc-ILD) is a significant contributor to both morbidity and mortality, its pathogenesis is largely unclear. Pulmonary function tests and high-resolution computed tomographic scanning continue to be the most effective tools to screen for lung involvement and to monitor for disease progression. More research and better biomarkers are needed to identify patients most at risk for developing SSc-ILD as well as to recognize which of these patients will progress to more severe disease. Although immunosuppression remains the mainstay of treatment, antifibrotic agents may offer new avenues of treatment for patients with SSc-ILD in the future.

Abstract
Cytokines and growth factors are key regulators of immune activation, vascular alteration and excessive production of extracellular matrix which are hallmark events in the pathogenesis of systemic sclerosis (SSc). They modulate cell-cell and cell-matrix interactions. In particular, cytokines play a central role in the immunopathogenesis of SSc on the basis of molecular pathways which are complex and not completely understood. The majority of cytokines that may be involved in SSc pathogenesis have effect upon or are derived from cells of the immune system, including both the innate and adaptive compartments. Novel therapies that block key mediators that drive the fibrotic response are being developed and appear as potential therapeutic tools in the treatment of SSc, highlighting the importance for an effective therapy targeted towards the molecular and cellular pathways. This article reviews cytokine biology in that context, with particular emphasis on immunopathology of the disease, therapeutic targeting and the way that current or emerging treatments for SSc might impact on cytokine biology.

Abstract
Background Mycophenolate is increasingly being used in the rheumatic diseases. Its main adverse effects are gastrointestinal, myelosuppression, and infection. These may limit use in systemic sclerosis (SSc) since gastrointestinal involvement is common. The objective of this study is to evaluate gastrointestinal adverse events of mycophenolate in SSc. Secondarily we evaluated other adverse events, and the effectiveness of mycophenolate in skin and lung disease. Methods A literature search of Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL (inception-2013) was performed. Studies reporting use of mycophenolate in SSc patients, adverse events, modified Rodnan skin score (MRSS), forced vital capacity (FVC), or diffusing capacity of carbon monoxide (DLCO) were included. The primary outcome was gastrointestinal events occurring after the initiation of mycophenolate. Secondary safety outcomes included myelosuppression, infection, malignancy, and death after the initiation of mycophenolate. Results 617 citations were identified and 21 studies were included. 487 patients were exposed to mycophenolate. The mean disease duration ranged between 0.8-14.1 years. There were 18 deaths and 90 non-lethal adverse events. The non-lethal adverse events included 43 (47.7%) gastrointestinal events, 34 (26%) infections, 6 (5%) cytopenias and 2 (2%) malignancies. The most common gastrointestinal events included diarrhea (n=18 (14%)), nausea (n=12 (9%)), and abdominal pain (n=3 (2%)). The rate of discontinuation ranged between 8%-40%. Seven observational studies reported improvement or stabilization in FVC, and 5 studies report stabilization or improvement in MRSS. Conclusion Mycophenolate-associated gastrointestinal adverse events are common in SSc, but not severe enough to preclude its use. Observational data suggests mycophenolate may be effective in improving or stabilizing interstitial lung disease, and skin involvement.

Abstract
OBJECTIVE We sought to retrospectively review a single-center experience using intravenous immunoglobulin (IVIG) for the treatment of refractory, active diffuse cutaneous systemic sclerosis (dcSSc). METHODS The mean modified Rodnan Skin score (mRSS) at baseline was compared to the mRSS at 6, 12, 18, and 24 months post-IVIG initiation by the paired Student t test. Changes in mRSS at 6 and 12 months were also compared to data from historical controls of 3 large, negative, multicenter, randomized clinical trials of other medications [D-penicillamine (D-pen), recombinant human relaxin (relaxin), and oral bovine type I collagen (collagen)] and to patients treated with mycophenolate mofetil (MMF) alone using the Student t test. RESULTS Thirty patients were treated with adjunctive IVIG (2 g/kg/mo) for refractory, active dcSSc. The mean baseline mRSS of our cohort was 29.6 ± 7.2, and this significantly decreased to 24.1 ± 9.6 (n = 29, p = 0.0011) at 6 months, 22.5 ± 10.0 (n = 25, p = 0.0001) at 12 months, 20.6 ± 11.8 (n = 23, p = 0.0001) at 18 months, and 15.3 ± 6.4 (n = 15, p < 0.0001) at 24 months. The mean change in mRSS at 6 months was not significantly different in the IVIG group (-5.3 ± 7.9) compared to the relaxin trial (-4.8 ± 6.99, p = 0.74) or MMF group (-3.4 ± 7.4, p = 0.26); however, at 12 months, the mean change in mRSS was significantly better in the IVIG group (-8 ± 8.3) than in the D-pen (-2.47 ± 8.6, p = 0.005) and collagen (-3.4 ± 7.12, p = 0.005) groups, and was comparable to the group of primary MMF responders (-7.1 ± 9, p = 0.67). CONCLUSION Our observational study suggests that IVIG may be an effective adjunctive therapy for active dcSSc in patients failing other therapies.

Abstract
Since activation of the immune system and a perivascular infiltrate of inflammatory cells are key features of SSc, immunosuppression has long been considered to be an anchor treatment. Non-selective immunosuppression remains central to the treatment of interstitial lung disease (ILD) and skin involvement, with CYC most widely used to obtain remission. The use of MTX as a first-line agent may be considered in the presence of skin involvement without ILD. More recently, MMF has shown encouraging results in observational studies, but still needs more formal evaluation to verify if it can be considered an alternative drug to CYC or a maintenance agent such as AZA. Rituximab has provided promising results in small open-label studies and other novel therapies targeting specific molecular and cellular targets are under evaluation. Patients with rapidly progressing diffuse cutaneous SSc should be evaluated for haematopoietic stem cell transplantation.

Abstract
SSc is a multiorgan disease with significant morbidity that is associated with poor health-related quality of life. Treatment of this condition is often organ based and non-curative. However, there are newer, potentially disease-modifying therapies available to treat certain aspects of the disease. This review focuses on old and new therapies in the management of SSc in clinical practice.

Abstract
BACKGROUND Rapamycin has been shown to exert an anti-fibrotic effect on skin fibrosis in a certain subset of patients with systemic sclerosis (SSc) and in bleomycin-treated animal models. OBJECTIVES To investigate the mechanism responsible for the anti-fibrotic effect of rapamycin especially by focusing on human α2(I) collagen (COL1A2) and matrix metalloproteinase 1 (MMP1) genes in normal and systemic sclerosis (SSc) dermal fibroblasts. METHODS The expression levels of type I procollagen and MMP1 proteins were analyzed by immunoblotting and the mRNA levels of COL1A2 and MMP1 genes were evaluated by quantitative real-time RT-PCR. The activities of COL1A2 and MMP1 promoters were determined by reporter analysis. RESULTS Rapamycin significantly decreased the levels of type I procollagen protein and COL1A2 mRNA, while significantly increasing the levels of MMP1 protein and mRNA in normal dermal fibroblasts. Similar effects of rapamycin were also observed in SSc dermal fibroblasts. Importantly, the inhibitory and stimulatory effects of rapamycin on the mRNA levels of COL1A2 and MMP1 genes, respectively, were significantly greater in SSc dermal fibroblasts than in normal dermal fibroblasts. In SSc dermal fibroblasts, rapamycin affected the expression of COL1A2 gene at the post-transcriptional level. In contrast, rapamycin altered the expression of MMP1 gene at the transcriptional level through the JNK/c-Jun signaling pathway in those cells. CONCLUSION Rapamycin has a potential to directly regulate the deposition of type I collagen in extracellular matrix through inhibiting type I collagen synthesis and promoting its degradation by MMP1, suggesting that this drug is useful for the treatment of SSc.

Abstract
During the last 10 years several new medications from hemato-oncology and transplantation medicine have been transferred to rheumatology. Additionally, medications which are approved for rheumatoid arthritis were increasingly also studied and used for other systemic inflammatory rheumatic diseases. This is especially the case for rituximab and mycophenolate and to a lesser extent also for leflunomide, tumor necrosis factor (TNF) antagonists, tocilizumab and abatacept. Recently, rituximab was approved for severe granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) after the publication of two prospective randomized trials in 2010. The situation concerning rituximab is much more problematic for systemic lupus erythematosus (SLE) where randomized placebo-controlled trials exist but unfortunately did not meet the primary endpoint requirements (too many highly effective additional forms of treatment in both arms and unsuitable endpoints), although data from registries suggest efficacy especially in cases resistant to treatment. In the case of mycophenolate (MPS) the problem with SLE is totally different. All prospective trials met the endpoints and in one trial MPS was even superior to azathioprine for treatment of lupus nephritis (LN) which led to the recommendation of MPS for induction and maintenance in LN by EULAR and EDTRA as well as more recently by the ACR. However, MPS still is not approved for SLE or LN. The present manuscript gives an overview of existing data for selected connective tissue diseases and vasculitides (for which at least larger retrospective case series or registry data exist) being treated with medications approved for other indications.

Abstract
Systemic sclerosis (SSc) is a chronic, multisystem connective tissue disease with protean clinical manifestations. Recent advances in understanding the pathogenic mechanisms have led to development of target-oriented and vasomodulatory drugs which play a pivotal role in treating various dermatological manifestations. An exhaustive literature search was done using Medline, Embase, and Cochrane library to review the recent concepts regarding pathogenesis and evidence-based treatment of salient dermatological manifestations. The concept of shared genetic risk factors for the development of autoimmune diseases is seen in SSc. It is divided into fibroproliferative and inflammatory groups based on genome-wide molecular profiling. Genetic, infectious, and environmental factors play a key role; vascular injury, fibrosis, and immune activation are the chief pathogenic factors. Vitamin D deficiency has been documented in SSc and correlates with the severity of skin involvement. Skin sclerosis, Raynaud's phenomenon (RP) with digital vasculopathies, pigmentation, calcinosis, and leg ulcers affect the patient's quality of life. Immunosuppressives, biologicals, and hematopoietic stem cell transplantation are efficacious in skin sclerosis. Endothelin A receptor antagonists, calcium-channel blockers, angiotensin receptor inhibitors, prostacyclin analogs, and phosphodiesterase type 5 (PDE-5) inhibitors are the mainstay in RP and digital vasculopathies. Pigmentation in SSc has been attributed to melanogenic potential of endothelin-1 (ET-1); the role of ET 1 antagonists and vitamin D analogs needs to be investigated. Sexual dysfunction in both male and female patients has been attributed to vasculopathy and fibrosis, wherein PDE-5 inhibitors are found to be useful. The future concepts of treating SSc may be based on the gene expression signature.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune disorder characterized by immune activation, vascular damage and an excessive accumulation of extracellular matrix proteins in the skin and internal organs. Despite its high morbidity and increased mortality, currently available treatment options for fibrotic manifestations of SSc remain limited and their clinical antifibrotic effects are borderline. In this review, novel insights from recently published clinical trials in SSc on treatment concepts such as mycophenolate mofetil, oral type I collagen, recombinant human relaxin and autologous hematopoietic stem cell transplantation are discussed. In the past decade the most significant progress in this field has been made by the identification of a large number of cellular and molecular key players in the pathogenesis of fibrotic disease manifestations. This has led to the identification of novel candidates as molecular targets for treatment of fibrotic diseases. On the basis of their level of evidence from preclinical studies and based on the availability of first clinical results, the most promising targets are presented including inhibitors of B-cells, tyrosine kinases, 5-hydroxytryptamin receptors, interleukin-6 and Wnt signalling.

Abstract
Systemic sclerosis (scleroderma) is unique among the rheumatic diseases because it presents the challenge of managing a chronic multisystem autoimmune disease with a widespread obliterative vasculopathy of small arteries that is associated with varying degrees of tissue fibrosis. The hallmark of scleroderma is clinical heterogeneity with subsets that vary in the degree of disease expression, organ involvement, and ultimate prognosis. Thus, the term scleroderma is used to describe patients who have common manifestations that link them together, whereas a highly variable clinical course exists that spans from mild and subtle findings to aggressive, life-threatening multisystem disease. The physician needs to carefully characterize each patient to understand the specific manifestations and level of disease activity to decide appropriate treatment. This is particularly important in treating a patient with scleroderma because there is no treatment that has been proven to modify the overall disease course, although therapy that targets specific organ involvement early before irreversible damage occurs improves both quality of life and survival. This review describes our approach as defined by evidence, expert opinion, and our experience treating patients. Scleroderma is a multisystem disease with variable expression; thus, any treatment plan must be holistic, yet at the same time focus on the dominant organ disease. The goal of therapy is to improve quality of life by minimizing specific organ involvement and subsequent life-threatening disease. At the same time the many factors that alter daily function need to be addressed, including nutrition, pain, deconditioning, musculoskeletal disuse, comorbid conditions, and the emotional aspects of the disease, such as fear, depression, and the social withdrawal caused by disfigurement.

Abstract
Heterogeneity in systemic sclerosis/SSc confounds clinical trials. We previously identified ‘intrinsic’ gene expression subsets by analysis of SSc skin. Here we test the hypotheses that skin gene expression signatures including intrinsic subset are associated with skin score/MRSS improvement during mycophenolate mofetil (MMF) treatment. Gene expression and intrinsic subset assignment were measured in 12 SSc patients’ biopsies and ten controls at baseline, and from serial biopsies of one cyclophosphamide-treated patient, and nine MMF-treated patients. Gene expression changes during treatment were determined using paired t-tests corrected for multiple hypothesis testing. MRSS improved in four of seven MMF-treated patients classified as the inflammatory intrinsic subset. Three patients without MRSS improvement were classified as normal-like or fibroproliferative intrinsic subsets. 321 genes (FDR <5%) were differentially expressed at baseline between patients with and without MRSS improvement during treatment. Expression of 571 genes (FDR <10%) changed between pre- and post-MMF treatment biopsies for patients demonstrating MRSS improvement. Gene expression changes in skin are only seen in patients with MRSS improvement. Baseline gene expression in skin, including intrinsic subset assignment, may identify SSc patients whose MRSS will improve during MMF treatment, suggesting that gene expression in skin may allow targeted treatment in SSc.

Abstract
Diffuse systemic sclerosis carries a high morbidity and mortality. The Prospective Registry of Early Systemic Sclerosis (PRESS), a multicentre incident cohort study of patients with early diffuse cutaneous systemic sclerosis, has the goal of advancing the understanding of disease pathogenesis and identifying novel biomarkers. In this review, PRESS investigators discuss the evidence pertaining to the more commonly used treatments for early diffuse SSc skin disease including methotrexate, mycophenolate, cyclophosphamide, azathioprine, and intravenous immunoglobulin. This review highlights the unmet need for effective treatment in early diffuse SSc as well as its more rigorous study. Nonetheless, the PRESS investigators aim to decrease intra- and inter-institutional variability in prescribing in order to improve the understanding of the clinical course of early diffuse SSc skin disease.

Enteric-coated mycophenolate sodium for progressive systemic sclerosis--a prospective open-label study with CT histography for monitoring of pulmonary fibrosis. Clin Rheumatol 2013; 32:673-8. [PMID: 23307324 DOI: 10.1007/s10067-012-2155-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2012] [Revised: 11/05/2012] [Accepted: 12/19/2012] [Indexed: 10/27/2022]
Abstract
The purpose of this study was to assess the impact of enteric-coated mycophenolate sodium (EC-MPS) on skin and pulmonary manifestations of patients with progressive systemic sclerosis (Ssc). A prospective, open-label single-centre trial with EC-MPS 2 × 720 mg/day over 12 months and a long-term follow-up of 50 months were conducted. Modified Rodnan skin score (mRSS) was used to assess the skin and pulmonary function tests to assess the pulmonary involvement. In order to quantify the extent of alveolitis/fibrosis via densitometry, the high attenuation value, median lung density and percentiles of lung tissue densities were obtained by high-resolution computed tomography. Eleven patients were included. Three patients had to stop medication before month 6 (2× side effects, 1× progression). For the remaining eight patients, the median mRSS was non-significantly reduced from 13.5 at baseline to 11 at month 12. According to the CT histography, median lung density and high attenuation values remained stable. However, the course of percentiles -200 to -300 and particularly -300 to -400 Hounsfield units slightly increased in seven of eight patients after 12 months, suggesting worsening of pulmonary involvement. Accordingly, median diffusing capacity for carbon monoxide showed a tendency to decline (75.1 % vs. 70.2) while forced vital capacity non-significantly improved (78.0 vs. 85.5 %) during the study. Four patients are still on EC-MPS without clinical signs of progression after 50 months follow-up. EC-MPS showed non-significant improvement of the skin. Pulmonary fibrosis remained stable with only a slight tendency towards progression which might be ascribed to the medication as well as the natural course of the disease. CT histography appears to be a sensitive method for the detection of progression of pulmonary fibrosis and therefore should be considered for further studies in Ssc.
