Park R, Nevskaya T, Baron M, Pope JE. Immunosuppression use in early systemic sclerosis may be increasing over time. JOURNAL OF SCLERODERMA AND RELATED DISORDERS 2022; 7:33-41. [PMID: 35386940 PMCID: PMC8922673 DOI: 10.1177/23971983211000971] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Accepted: 02/06/2021] [Indexed: 02/03/2023]
Abstract
Background Immunosuppression remains the main treatment for progressing skin involvement, interstitial lung disease and inflammatory joint or muscle disease in systemic sclerosis. This study investigated the pattern and trends in immunosuppressive agents used in early systemic sclerosis (diagnosed before and after 2007) to determine whether the changes in the preferred type, timing and combination of immunosuppression took place over the past decade. Methods In total, 397 Canadian Scleroderma Research Group database patients (183 diffuse cutaneous systemic sclerosis and 214 limited cutaneous systemic sclerosis) who had baseline and follow-up visits within 3 years (mean: 1.8 ± 0.8) after disease onset were included: 82% females, age at diagnosis 53 ± 13 years. Bivariate, chi-square, analysis of variance and adjusted regression analyses were used. Results In total, 115 diffuse cutaneous systemic sclerosis patients (63%) and 62 limited cutaneous systemic sclerosis (29%) received immunosuppressive drugs, most commonly methotrexate, followed by mycophenolate mofetil and cyclophosphamide. In diffuse cutaneous systemic sclerosis, immunosuppressants were prescribed after 2007 more often (74% vs 50%, p = 0.001), especially methotrexate (p = 0.02) and mycophenolate mofetil (p = 0.04), and earlier (peak at 2 years after onset). Immunosuppressive therapy was associated with male gender, interstitial lung disease, anti-Scl70 positivity, ACA negativity and inflammatory joint disease in limited cutaneous systemic sclerosis and with ACA negativity and a higher modified Rodnan skin score in diffuse cutaneous systemic sclerosis. Multivariate regression analysis showed that the use of immunosuppressants after 2007 was predicted only by ACA negativity in limited cutaneous systemic sclerosis and by younger age in diffuse cutaneous systemic sclerosis. Conclusion Over the past decade, there has been a trend to prescribe immunosuppressants more often and earlier in diffuse cutaneous systemic sclerosis patients, regardless of modified Rodnan skin score. Methotrexate is being more frequently used, and mycophenolate mofetil has gained favour over cyclophosphamide. Autoantibody status was the most consistent predictor of immunosuppressive therapy.

Abstract
Systemic sclerosis is an autoimmune disease that prominently leads to skin and tissue fibrosis. The efficacy of autologous stem cell transplantation not only attests to the autoimmune pathophysiology for systemic sclerosis, but also for interstitial lung disease as its most frequent manifestation of fatal organ involvement. Accordingly, a variety of immunomodulatory therapies were tried on patients with systemic sclerosis-interstitial lung disease. Until very recently, all of these therapeutic approaches constituted off-label treatment for systemic sclerosis, given that neither of these therapies was approved by the United States Food and Drug Administration (FDA) or the European Medicines Agency. For tocilizumab, this has now changed with FDA approval in March 2021. Already 2020, nintedanib, which is an antifibrotic drug that does not target autoimmunity, became the first approved drug for interstitial lung disease in systemic sclerosis. The present review analyzes the evidence for immunomodulatory treatment of systemic sclerosis-associated interstitial lung disease. The review focuses on randomized controlled trials, which provides evidence for the effects of drugs such as cyclophosphamide, mycophenolate, rituximab and tocilizumab.

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
OBJECTIVE To test whether the use of rituximab (RTX) is effective and safe as a rescue therapy add-on treatment to mycophenolate (MMF) in patients with progressive systemic sclerosis-associated interstitial lung disease (SSc-ILD) in whom conventional immunosuppressants (IS) have failed. METHODS Longitudinal retrospective observational study of a cohort of patients with SSc-ILD that started treatment with RTX due to ongoing lung function impairment despite treatment with glucocorticoids and IS (cyclophosphamide and/or MMF). All patients were treated with 2 or more cycles of RTX and evaluated for at least 12 months. RESULTS Twenty-four patients were included. Before initiation of RTX the mean decline in%pFVC and %pDLCO during the previous 2 years (delta) was -12.9% and -12.5%, respectively. After 1 year of treatment with RTX, a significant improvement in %pFVC (∆+8.8% compared to baseline, 95% CI: -13.7 to -3.9; p = 0.001) and%pDLCO (∆+4.6%, 95% CI: -8.2 to -0.8; p = 0.018) was observed. In addition, there was a significant reduction in the median dose of prednisone and it could be suspended in 25% of patients. At 2 years of treatment, RTX had been discontinued in 9 patients (due to adverse events in 3 cases and inefficacy in 6). In the 15 patients (62.5%) that completed 24 months of therapy, the statistically significant amelioration in pulmonary function test parameters was maintained: ∆%pFVC: +11.1% (95% CI: -17.6 to -4.5; p = 0.003) and ∆%pDLCO: +8.7% (95% CI: -13.9 to -8.3; p = 0.003). CONCLUSION Based on our results, RTX's use as an add-on treatment to MMF appears to be effective as a rescue therapy in patients with a more aggressive SSc-ILD phenotype.

Abstract
Interstitial lung disease (ILD) is one of the most serious pulmonary complications of connective tissue diseases (CTDs) and it is characterized by a deep impact on morbidity and mortality. Due to the poor knowledge of CTD-ILD’s natural history and due to the difficulties related to design of randomized control trials, there is a lack of prospective data about the prevalence, follow-up, and therapeutic efficacy. For these reasons, the choice of therapy for CTD-ILD is currently very challenging and still largely based on experts’ opinion. Treatment is often based on steroids and conventional immunosuppressive drugs, but the recent publication of the encouraging results of the INBUILD trial has highlighted a possible effective and safe use of antifibrotic drugs as a new therapeutic option for these subjects. Aim of this review is to summarize the available data and recent advances about therapeutic strategies for ILD in the context of various CTD, such as systemic sclerosis, idiopathic inflammatory myopathy and Sjogren syndrome, systemic lupus erythematosus, mixed connective tissue disease and undifferentiated connective tissue disease, and interstitial pneumonia with autoimmune features, focusing also on ongoing clinical trials.

Abstract
Systemic sclerosis (SSc) is a progressive and often devastating disease characterized by autoimmune dysfunction, vasculopathy, and fibrosis. Interstitial lung disease (ILD) is identified in the majority of patients with SSc and is the leading cause of SSc-related mortality. Although clinical manifestations and ILD severity vary among patients, lung function typically declines to the greatest extent during the first 3-4 years after disease onset. We aim to provide an overview of SSc-associated ILD (SSc-ILD) with a focus on current and emerging tools for early diagnosis of ILD and current and novel treatments under investigation. Early detection of ILD provides the opportunity for early therapeutic intervention, which could improve patient outcomes. Thoracic high-resolution computed tomography is the most effective method of identifying ILD in patients with SSc; it enables detection of mild lung abnormalities and plays an important role in monitoring disease progression. Cyclophosphamide and mycophenolate mofetil are the most commonly prescribed treatments for SSc-ILD. Recently, nintedanib (an antifibrotic) was approved by the Food and Drug Administration for patients with SSc-ILD; it is indicated for slowing the rate of decline in pulmonary function. However, there is a need for additional effective and well-tolerated disease-modifying therapy. Ongoing studies are evaluating other antifibrotics and novel agents. We envision that early detection of lung involvement, combined with the emergence and integration of novel therapies, will lead to improved outcomes in patients with SSc-ILD.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune disease, characterized by vasculopathy and fibrosis of the skin and internal organs. This disease is still considered incurable and is associated with a high risk of mortality, which is related to fibrotic events. An early diagnosis is useful for preventing complications, and targeted therapies reduce disease progression and ameliorate patients’ quality of life. Nevertheless, there are no validated biomarkers for early diagnosis with predictive prognostic value. Exosomes are membrane vesicles, transporting proteins and nucleic acids that may be delivered to target cells, which influences cellular behavior. They play important roles in cell–cell communication, both in physiological and pathological conditions, and may be useful as circulating biomarkers. Recent evidences suggest a role for these microvesicles in the three main aspects related to the pathogenesis of SSc (immunity, vascular damage, and fibrosis). Moreover, exosomes are of particular interest in the field of nano-delivery and are used as biological carriers. In this review, we report the latest information concerning SSc pathogenesis, clinical aspects of SSc, and current approaches to the treatment of SSc. Furthermore, we indicate a possible role of exosomes in SSc pathogenesis and suggest their potential use as diagnostic and prognostic biomarkers, as well as therapeutic tools.

Abstract
Systemic sclerosis (SSc) is a chronic systemic disease characterized by microvasculopathy, immune activation, and extensive collagen deposition. Microvasculopathy and immune activation occur very early in the disease process. Evidence from animal models and in vitro studies indicate that T-cells and B-cells activate fibroblasts to produce collagen. Traditional immunosuppressants, cyclophosphamide(CyP), methotrexate(MTX), and more recently mycophenolate mofetil(MMF), may prove more effective if used very early in the disease course. These drugs showed some benefit in skin (MTX, CyP, MMF) and lung function (CyP, MMF). Biologicals, such as intravenous immunoglobulin (IVIg), belimumab(Beli), tocilizumab(TCZ), abatacept(Aba), rituximab(RTX) and fresolimumab(Fresu) appear promising as they exhibited some benefit in skin (IVIg, Beli, TCZ, Aba, RTX, Fresu), hand function (IVIg), and joints (IVIg, TCZ, Aba). Autologous stem cell transplantation showed the best therapeutic efficacy on skin and internal organs, and looks very promising, as modification of transplantation immunosuppression is decreasing the early high mortality.

Abstract
Several effective drugs have been identified for the treatment of systemic sclerosis (SSc). However, in advanced cases, not only their effectiveness is reduced but they may be also harmful due to their side-effects. Therefore, early diagnosis and early treatment is most important for the treatment of SSc. We established diagnostic criteria for SSc in 2003 and early diagnostic criteria for SSc in 2011, for the purpose of developing evaluation of each organ in SSc. Moreover, in November 2013, the American College of Rheumatology and the European Rheumatology Association jointly developed new diagnostic criteria for increasing their sensitivity and specificity, so we revised our diagnostic criteria and severity classification of SSc. Furthermore, we have revised the clinical guideline based on the newest evidence. In particular, the clinical guideline was established by clinical questions based on evidence-based medicine according to the New Minds Clinical Practice Guideline Creation Manual (version 1.0). We aimed to make the guideline easy to use and reliable based on the newest evidence, and to present guidance as specific as possible for various clinical problems in treatment of SSc.

Abstract
Systemic sclerosis (SSc) is an intractable multifaceted disease with high mortality. Although its pathogenesis is not fully understood, recent studies have advanced our knowledge on SSc. The cardinal pathological features of SSc are autoimmunity, vasculopathy, and fibrosis. The B cells in SSc are constitutively activated and lead to the production of a plethora of autoantibodies, such as anti-topoisomerase I and anti-centromere antibodies. In addition to these autoantibodies, which are valuable for diagnostic criteria or biomarkers, many other autoantibodies targeting endothelial cells, including endothelin type A receptor and angiotensin II type I receptor, are known to be functional and induce activation or apoptosis of endothelial cells. The autoantibody-mediated endothelial cell perturbation facilitates inflammatory cell infiltration, cytokine production, and myofibroblastic transformation of fibroblasts and endothelial cells. Profibrotic cytokines, such as transforming growth factor β, connective tissue growth factor, interleukin 4/interleukin 13, and interleukin 6, play a pivotal role in collagen production from myofibroblasts. Specific treatments targeting these causative molecules may improve the clinical outcomes of patients with SSc. In this review, we summarize recent topics on the pathogenesis (autoantibodies, vasculopathy, and fibrosis), animal models, and emerging treatments for SSc.

Imunosuppressive treatment (IS) is used in patients with SSc for various organ manifestations mainly to ameliorate progression of SSc-ILD. Data on everyday IS prescription patterns and clinical courses of lung function during and after therapy are scarce. Methods We analysed patients fulfilling American College of Rheumatology (ACR)/European League against Rheumatism (EULAR) 2013 criteria for SSc-ILD and at least one report of IS. Types of IS, pulmonary function tests (PFT) and PFT courses during IS treatment were evaluated. Results EUSTAR contains 3778/11,496 patients with SSc-ILD (33%), with IS in 2681/3,778 (71%). Glucocorticoid (GC) monotherapy was prescribed in 30.6% patients with GC combinations plus cyclophosphamide (CYC) (11.9%), azathioprine (AZA) (9.2%), methotrexate (MTX) (8.7%), or mycophenolate mofetil (MMF) (7.3%). Intensive IS (MMF + GC, CYC or CYC + GC) was started in patients with the worst PFTs and ground glass opacifications on imaging. Patients without IS showed slightly less worsening in forced vital capacity (FVC) when starting with FVC 50–75% or >75%. GC showed negative trends when starting with FVC <50%. Regarding diffusing capacity for carbon monoxide (DLCO), negative DLCO trends were found in patients with MMF. Conclusions IS is broadly prescribed in SSc-ILD. Clusters of clinical and functional characteristics guide individualised treatment. Data favour distinguished decision-making, pointing to either watchful waiting and close monitoring in the early stages or start of immunosuppressive treatment in moderately impaired lung function. Advantages of specific IS are difficult to depict due to confounding by indication. Data do not support liberal use of GC in SSc-ILD.

Mycophenolate mofetil for scleroderma-related interstitial lung disease: A real world experience. PLoS One 2017; 12:e0177107. [PMID: 28542177 PMCID: PMC5444590 DOI: 10.1371/journal.pone.0177107] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2016] [Accepted: 04/21/2017] [Indexed: 11/30/2022] Open
Abstract
Background and objective Interstitial lung disease (ILD) remains the number one cause of mortality in scleroderma (SSc). Our goal was to determine the effectiveness of mycophenolate mofetil (MMF) in treating SSc-ILD in a retrospective study. Methods A retrospective, computer-assisted search was performed to identify patients with SSc-ILD treated with MMF from 1997 through 2014. We used a novel software tool, Computer-Aided Lung Informatics for Pathology Evaluation and Rating (CALIPER), to quantify parenchymal lung abnormalities on high-resolution computed tomography. Lung function was evaluated at baseline, 6, 12, and 24 months of MMF therapy. Results We identified 46 patients (28 females) with SSc-ILD (mean age at diagnosis 55 y) treated with MMF for at least 1 year (majority on 2 gm/day). Twenty-one patients (45.7%) stopped using MMF during the follow up period after the first 12 months, and they took MMF for a median of 2.12 years (range, 0.91–8.93 years). Only 4 discontinued MMF because of disease progression. Compared to baseline, the mean percentage change in forced vital capacity (95% CI) at 6, 12, and 24 months, respectively, was 1.01% (−2.38%-4.39%) (n = 26), 2.06% (−1.09%-5.22%) (n = 31), and −0.07% (−3.31%-3.17%) (n = 30), and the mean percentage change in ILD as measured by CALIPER (95% CI) was −5.40% (−18.62%-7.83%) (n = 18), −1.51% (−14.69%-11.68%) (n = 17), and −8.35% (−20.71%-4.02%) (n = 22).The mean right ventricular systolic pressure (RVSP) remained stable over the study period. Conclusions MMF is well tolerated and slows the rate of decline in lung function in SSc-ILD patients, even at doses lower at 3 g/day.

Abstract
BACKGROUND Currently available antifibrotic treatments may slow down disease progression in idiopathic pulmonary fibrosis (IPF), but are associated with potentially significant side effects and are costly. Mycophenolate mofetil (MMF) is well known for its potent immunosuppressive properties and possesses important antiproliferative and antifibrotic effects. The safety and effectiveness of MMF in IPF is unknown. METHODS We performed a retrospective multicohort analysis of IPF patients treated with MMF compared to those treated with either ineffective/harmful treatments or no treatment. Longitudinal change in forced vital capacity (FVC) between the groups was analyzed using a mixed model with random intercept and slope allowing for repeated measures within subjects. Categorical change in FVC, median overall survival, and adverse events were also assessed. RESULTS Forty-one IPF patients were included: 11 treated with MMF, 20 treated with ineffective/harmful agents (such as prednisone, azathioprine, and/or NAC), and 10 did not receive any specific treatment for their IPF. After one year, there was a trend towards reduced FVC decline in the MMF-treated group (-76.3 mL, -2.4% of predicted) compared to the non-MMF-treated (-165 mL, -8.9% of predicted) and the no-treatment (-239 mL, -11.5% of predicted) groups, respectively. By categorical change, there was a trend towards greater FVC stability in the MMF-treated group (87.5%) compared to the non-MMF-treated (57%) and the no-treatment groups (50%), respectively. MMF-treated IPF patients had a trend towards improved median overall survival (40.3 months) compared to the non-MMF-treated (25.5 months) and the no-treatment (29.3 months) groups, respectively. Treatment-related adverse events were not different between groups; however, very few adverse events were reported overall. CONCLUSIONS MMF treatment was associated with potentially clinically important trends toward reduced annual FVC decline (similar to approved antifibrotics), greater FVC stability and improved overall survival in IPF patients. MMF was generally safe, well tolerated, and relatively inexpensive. Future prospective studies of MMF in combination with antifibrotic therapy in IPF are needed.

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.

Mycophenolate mofetil following cyclophosphamide in worsening systemic sclerosis-associated interstitial lung disease. JOURNAL OF SCLERODERMA AND RELATED DISORDERS 2016.

Abstract
Objectives Randomized controlled trials have shown that cyclophosphamide (CYC) was an option in systemic sclerosis-associated interstitial lung disease (SSc-ILD). The observed improvement disappeared after CYC was stopped suggesting that a maintenance regimen was mandatory. Immunosuppressants were suggested to be more effective in patients with worsening (i.e., with worsening of dyspnea and/or pulmonary functional tests) SSc-ILD. We aimed to assess the efficacy of mycophenolate mofetil (MMF) as a maintenance regimen after CYC in worsening SSc-ILD. Methods All patients (n = 20) with worsening SSc-ILD were retrospectively included. Treatment consisted of 6 to 12 monthly pulses of CYC followed by MMF and response was assessed by the evolution of the forced vital capacity (FVC) and carbon monoxide diffusing capacity (DLCO) during follow-up. Results At the end of CYC pulses, SSc-ILD had improved in 7 (35%) patients, stabilized in 10 (50%) (i.e., 85% of responders) and worsened in 3 (15%) when compared to baseline. After 6 months of MMF, 70% were still responders while 30% had worsened when compared to baseline (i.e., before CYC). After 12 months on MMF, 55% were responders and 45% had worsened when compared to baseline. Evolution of the FVC slope significantly improved on CYC as well as on MMF. Conclusions A strategy combining IV CYC followed by maintenance MMF for worsening SSc-ILD was associated with stabilization or improvement of pulmonary function tests in only 55% of patients after 12 months of MMF. This suggests that careful monitoring for worsening is mandatory during MMF maintenance and that improvement in managing worsening SSc-ILD is still needed.

Abstract
Interstitial lung disease (ILD) is common in systemic sclerosis (SSc) patients and despite recent advances in the treatment is, at present, the major cause of death. Today, an early diagnosis of ILD is possible, and is mandatory to improve the prognosis of the disease. Pulmonary function tests and high-resolution computed tomography remain the mainstay for the diagnosis of SSc-ILD, but there is a growing interest in lung ultrasound. Recently, the correlation between severity of fibrosis and some peripheral blood biomarkers has been described. Nonselective immunosuppressors are still the main treatment for ILD, with cyclophosphamide (CYC) most widely used to obtain remission. Novel therapies towards specific molecular and cellular targets have been suggested; in particular, rituximab (RTX) has shown promising results, but further research is needed. It is of paramount importance to define the severity of the disease and the risk of progression in order to define the need for treatment and the treatment intensity. We propose the division of the treatment strategies at our disposal to induce remission into three categories: high intensity (haematopoietic stem cell transplantation), medium intensity (CYC and RTX) and low intensity (azathioprine (AZA) and mycophenolate mofetil (MMF)). After obtaining remission, maintenance treatment with AZA or MMF should be started. In this review we explore new advances in the pathogenesis, diagnosis and treatment of SSc-ILD.

Abstract
BACKGROUND Scleroderma is a systemic autoimmune disease characterized mainly by skin manifestations and involvement of various visceral organs, especially the lungs. Lung involvement is the leading cause of mortality in patients with scleroderma. There are data to suggest that cyclophosphamide (CYC) and mycophenolate mofetil (MMF) are effective in the management of scleroderma interstitial lung disease (SSc-ILD) but no head to head comparative data are available to date. METHODS For the last 3 years, patients with SSc-ILD have been treated at our centre by protocol-based administration of intravenous CYC and MMF. Results of lung function tests (spirometry) were recorded at baseline, 3 months and 6 months in every patient. The clinical records of patients with systemic sclerosis and significant ILD, who were not previously exposed to any immunosuppressant and were treated with MMF OR CYC, were reviewed. The efficacy of treatment was assessed by the change in forced vital capacity on spirometry. RESULTS Of the total 57 patients included in the analysis, 34 were treated with MMF and 23 were treated with CYC. Mean duration of illness was 4.19 ± 2.82 years in the MMF and 6.04 ± 5.96 years in the CYC group. After 6 months of therapy, FVC increased by 10.84 ± 13.81 % in the CYC group and by 6.07 ± 11.92 % in the MMF group. This improvement from baseline was statistically significant in both groups (P < 0.01). The improvement was comparable with no statistically significant differences between groups (P = 0.373). There were no major adverse events reported in either arm. CONCLUSION Both MMF and CYC were equally effective in stabilizing lung function in patients with scleroderma and ILD.

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.

Abstract
Systemic sclerosis (SSc) is a disorder characterized by immune dysfunction, microvascular injury, and fibrosis. Organ involvement in patients with SSc is variable; however, pulmonary involvement occurs in up to 90% of patients with SSc. Interstitial lung disease (ILD) is a major cause of mortality and, thus, a major determinant in the prognosis of patients with SSc. This review summarizes current findings about the characteristics of ILD in patients with SSc, selection of patients with SSc-ILD who are candidates for the treatment, and current treatment options.

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
Interstitial lung disease (ILD) is an important manifestation of collagen vascular diseases. It is a common feature of scleroderma, and also occurs in dermatomyositis and polymyositis, mixed connective tissue disease, Sjogren’s syndrome, rheumatoid arthritis, systemic lupus erythematosus, and Antineutrophil cytoplasmic antibody-associated vasculitis. When present, it is associated with increased morbidity and mortality, thus making early diagnosis important. In fact, in many patients, ILD may be the first manifestation of a collagen vascular disease. The most common symptoms are cough and dyspnea. The diagnosis is made based on pulmonary function tests showing restrictive lung disease and impaired oxygen diffusion and chest imaging showing ground glass infiltrates, interstitial thickening, and/or fibrosis. The most common histologic finding on lung biopsy is non-specific interstitial pneumonia, though organizing pneumonia and usual interstitial pneumonia may also be seen. Treatment is focused on addressing the underlying collagen vascular disease with immunosuppression, either with corticosteroids or a steroid-sparing agent such as cyclophosphamide, azathioprine, or mycophenolate, although the optimal agent and duration of therapy is not known. There are few clinical trials to guide therapy that focus specifically on the progression of ILD. The exception is in the case of scleroderma-associated ILD, where cyclophosphamide has been shown to be effective.

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
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
To assess the effect of mycophenolate mofetil (MMF) on pulmonary functions in patients with systemic sclerosis-associated lung disease (SSc-ILD) who experienced an inadequate response to first line cyclophosphamide (CYC) therapy. Twelve consecutive SSc-ILD patients who received MMF due to inadequate response to CYC as a first line agent, were retrospectively reviewed. Over the course of 2 years, pulmonary function tests (PFT) and high-resolution computed tomography (HRCT) scans were performed. Following initial baseline tests, PFTs were continued at a frequency of every 6 months and HRCT scans were performed every 12 months. After MMF treatment, values of forced vital capacity (FVC) and diffusing capacity for carbon monoxide (DLCO) improved in three (25%) and two (16.6%) patients, respectively. It is also noted that the evaluation of serial HCRT scans showed no change in 54.5% of patients. Our case series suggested that PFT and imaging scores seemed to be stabilized by MMF in SSc-ILD patients who were inadequate responders to CYC.

Abstract
The connective tissue diseases (CTDs) are a group of systemic disorders characterized by autoimmunity and autoimmune-mediated organ damage. The lung is a frequent target and all components of the respiratory system are at risk. Interstitial lung disease (ILD) represents a broad group of diffuse parenchymal lung injury patterns characterized by varying degrees of inflammation and fibrosis, is a common manifestation of CTD particularly common in systemic sclerosis, polymyositis/dermatomyositis, and rheumatoid arthritis, and is a leading cause of significant morbidity and mortality. The lung injury patterns of CTD-associated ILD (CTD-ILD) mirror those of idiopathic interstitial pneumonia and may arise at any time during the course of the CTD or may be the first manifestation of CTD. Patients with CTD that present with respiratory failure often present significant diagnostic dilemmas. Thorough and comprehensive assessments to exclude respiratory *infection, acute interstitial pneumonia, medication toxicity, pulmonary embolism, cardiac dysfunction, and diffuse alveolar hemorrhage are the fundamental components for the evaluation of such patients. Furthermore, patients with CTD are also at risk of acute exacerbations of underlying ILD. Acute exacerbations are manifested by subacute respiratory deterioration with worsening hypoxemia in the setting of new radiographic abnormalities. The prognosis of patients with CTD having respiratory failure is often quite poor, highlighting the need for prompt and thorough clinical assessments to determine the underlying etiology and implementation of appropriate therapeutic strategies.

Abstract
OBJECTIVE Cyclophosphamide is considered the treatment of choice for interstitial lung disease (ILD) secondary to systemic sclerosis (SSc), albeit having a minimal effect. Although controlled evidence does not exist, mycophenolate is used increasingly in clinical practice as an alternative. We aimed to compare the long-term efficacy of these drugs. METHODS Patients from our SSc cohort who received mycophenolate for over 1 year for progressive ILD were 1:1 matched for age, gender, and baseline forced vital capacity (FVC ±3 %) with cyclophosphamide-treated patients. Changes in FVC, total lung capacity (TLC), diffusion capacity for carbon monoxide (DLCO), and high-resolution computed tomography (HRCT) scans were compared between groups. Changes in pulmonary function tests (PFTs) over at least 1 year in six unmatched control patients, who had denied mycophenolate or cyclophosphamide, also were examined. RESULTS FVC, TLC, and DLCO did not change significantly in either mycophenolate (from 79.0 ± 12.5 to 80.2 ± 8.1 to 81.2 ± 11.4, from 71.5 ± 16.1 to 74.3 ± 10.8 to 71.8 ± 13.0, from 56.8 ± 12.0 to 55.2 ± 9.9 to 50.6 ± 8.5, respectively) or cyclophosphamide group (from 77.3 ± 12.5 to 79.7 ± 10.3 to 82.5 ± 12.9, from 64.7 ± 14.9 to 68.6 ± 16.0 to 66.1 ± 15.5, from 53.1 ± 14.3 to 56.4 ± 13.5 to 56.3 ± 6.7, respectively), after 1 or 2 years of treatment. PFTs also remained stable in the control group. In either the mycophenolate or cyclophosphamide groups, six patients remained stable, three improved, and one deteriorated according to the definitions of the American Thoracic Society. However, and despite the fact that patients in the cyclophosphamide group had more extended ILD at baseline, a deterioration of lung HRCT findings at 2 years was noticed after mycophenolate (from 10.0 ± 8.9 to 12.7 ± 8.2, p = 0.039) but not after cyclophosphamide. CONCLUSIONS Although these results derive from patients selected for receiving at least 1 year of treatment and therefore they do not represent an intention-to-treat cohort, an eagerness to replace cyclophosphamide by mycophenolate in SSc-associated ILD treatment is not supported.

Abstract
OBJECTIVE Small series suggest mycophenolate mofetil (MMF) is well tolerated and may be an effective therapy for connective tissue disease-associated interstitial lung disease (CTD-ILD). We examined the tolerability and longitudinal changes in pulmonary physiology in a large and diverse cohort of patients with CTD-ILD treated with MMF. METHODS We identified consecutive patients evaluated at our center between January 2008 and January 2011 and prescribed MMF for CTD-ILD. We assessed safety and tolerability of MMF and used longitudinal data analyses to examine changes in pulmonary physiology over time, before and after initiation of MMF. RESULTS We identified 125 subjects treated with MMF for a median 897 days. MMF was discontinued in 13 subjects. MMF was associated with significant improvements in estimated percentage of predicted forced vital capacity (FVC%) from MMF initiation to 52, 104, and 156 weeks (4.9% ± 1.9%, p = 0.01; 6.1% ± 1.8%, p = 0.0008; and 7.3% ± 2.6%, p = 0.004, respectively); and in estimated percentage predicted diffusing capacity (DLCO%) from MMF initiation to 52 and 104 weeks (6.3% ± 2.8%, p = 0.02; 7.1% ± 2.8%, p = 0.01). In the subgroup without usual interstitial pneumonia (UIP)-pattern injury, MMF significantly improved FVC% and DLCO%, and in the subgroup with UIP-pattern injury, MMF was associated with stability in FVC% and DLCO%. CONCLUSION In a large diverse cohort of CTD-ILD, MMF was well tolerated and had a low rate of discontinuation. Treatment with MMF was associated with either stable or improved pulmonary physiology over a median 2.5 years of followup. MMF appears to be a promising therapy for the spectrum of CTD-ILD.

Abstract
PURPOSE OF REVIEW Advances in genetics and clinical diagnostics, along with recently described clinical entities and refined classification schemes, have improved our understanding of diffuse and interstitial lung diseases in children. This review presents recent updates in these disorders in the context of systemic inflammatory conditions. RECENT FINDINGS Classification of childhood diffuse lung disease (DLD) using adult paradigms is not useful. Distinct clinical-pathologic entities exist in children. Infants are more likely to present with genetic and developmental disorders, and older children with inflammatory and immune-mediated conditions. A combination of clinical evaluation, high-resolution computed tomography scanning, pulmonary function testing and serology, with bronchoscopy and surgical lung biopsy in selected cases, is most useful in the evaluation of DLD in the context of rheumatologic conditions. Common causes of DLD, such as infection, especially in the setting of immunodeficiency, must be ruled out. Optimal therapy for specific disorders will require careful analysis of data from national registries. Emerging use of biomarkers and high-throughput molecular analysis will yield novel insight into these disorders. SUMMARY In the setting of known or suspected rheumatologic disorders, diagnosis and management of DLD are challenging, and require close collaboration among rheumatologists, pulmonologists, and other specialists.

Abstract
The management of patients with systemic sclerosis (SSc) can be challenging because disease-associated damage is often difficult to reverse and curative therapies are not yet available. Early identification and appropriate monitoring of patients with SSc is, therefore, critical so that active disease can be controlled and tissue damage prevented or delayed. However, early diagnosis of SSc is often difficult because the early clinical stages of the disease can be very similar to that of other autoimmune conditions. Screening for major organ manifestations of SSc, particularly interstitial lung disease, pulmonary hypertension, renal involvement and cardiac disease is a priority because involvement of these organs is associated with shorter life expectancies and early intervention might prevent disease progression. The prevention and management of digital ischaemia is also important as appropriate therapy often prevents substantial morbidity and functional loss. Treating gastrointestinal dysmotility can usually be managed using proton pump inhibitors and promotility agents, although in severe cases total parenteral nutrition is required. Calcinosis in patients with SSc is another common challenge that requires appropriate disease management and pain control. Each of these topics, which are relevant to both physicians and patients with SSc, are reviewed in further detail herein.

Abstract
Background. Interstitial lung disease (ILD) is the most common complication of systemic sclerosis (SSc) with treatment ineffective. Objective: The aim of this meta-analysis was to provide an estimate of the safety and efficacy profile of Mycophenolate Mofetil (MMF) or sodium (MMS) in SSc-ILD patients. Materials and Methods. All studies were reviewed systematically. The main end-points were safety and efficacy profile as estimated by forced vital capacity (FVC)% and diffusion capacity of the lung for carbon monoxide (DLCO)% of the predicted normal value (%pred.) before and after treatment in patients with SSc-ILD. Quality assessment and data extraction were performed independently by two reviewers. Results. Seventeen studies were reviewed systematically. Six studies, one prospective, were eligible for analysis encompassing 69 patients, including 10 subjects from our, yet unpublished, retrospective study. There was no statistically significant difference in both efficacy outcomes of interest, including FVC% pred. (weighted mean difference 1.48, 95% confidence interval (CI): −2.77 to 5.72, P = 0.49) and DLCO % pred. (weighted mean difference −0.83, 95% CI: −4.75 to 3.09, P = 0.93). No cases of clinically significant side effects were documented. Conclusions. Meta-analysis data suggest that MMF is a safe therapeutic modality which was associated with functional stabilization in patients with SSc-ILD.

Abstract
BACKGROUND T lymphocytes induce the transformation of fibroblasts into myofibroblasts, the main mediators of fibrogenesis. The inosine 5'-monophosphate dehydrogenase inhibitor mycophenolate mofetil (MMF) and the anti-CD25 monoclonal antibody daclizumab (DCZ) have been reported to suppress the proliferation of T lymphocytes. AIM To evaluate the preventive effects of MMF and DCZ in early stages of bleomycin (BLM)-induced scleroderma. METHODS This study involved five groups of Balb/c mice (n = 10 per group). Mice in four of the groups were injected subcutaneously (SC) with BLM [100 μg/day in 100 μL phosphate-buffered saline (PBS)] for 4 weeks; the remaining (control) group received only 100 μL PBS. Three of the BLM-treated groups also received either intraperitoneal MMF 50 or 150 mg/kg/day, or SC DCZ 100 μg/week. At the end of the fourth week, all mice were killed, and blood and tissue samples were obtained for further analysis. RESULTS In the BLM-treated group, increases were seen in inflammatory-cell infiltration, α-smooth muscle actin-positive (α-SMA+) fibroblastic cell count, tissue hydroxyproline content, and dermal thickness. Dermal fibrosis was histopathologically prominent. In BLM-treated mice also given MMF or DCZ, inflammatory-cell infiltration, tissue hydroxyproline content and dermal thickness were decreased. In the MMF groups, decreases were also noted in α-SMA+ fibroblastic cell count. CONCLUSION In this BLM-induced dermal fibrosis model, MMF and DCZ treatments prevented the development of dermal fibrosis. Further studies are needed to evaluate whether targeting T lymphocytes is effective in resolving pre-existing fibrosis in human scleroderma.

Abstract
Background. Idiopathic pulmonary fibrosis (IPF) is a progressive fibrotic interstitial lung disease with ineffective treatment. Mycophenolate mofetil (MMF) is an immunomodulatory agent which inhibits lymphocyte proliferation. Objective. We sought to determine the safety and efficacy profile of MMF in IPF patients. Methods. We retrospectively identified ten patients, who met the ATS/ERS 2000 criteria for IPF and received MMF 2 gr/day for 12 months. All of them had routine laboratory, pulmonary function and radiological (high resolution computed tomography-HRCT) data available and were enrolled in the study. Forced vital capacity (FVC), total lung capacity (TLC), diffusion capacity of the lung for carbon monoxide (DLCO), 6-minute walking distance (6MWD), HRCT scans and routine laboratory data at treatment onset were compared with respective values 12 months after treatment onset. Results. There were no significant alterations in FVC, TLC, DLCO and 6MWD pre- and 6 and 12 months post-treatment. HRCT evaluation showed deterioration of the total extent of disease (P = 0.002) and extent of ground-glass opacity (P = 0.02). No cases of clinically significant infection, leucopenia, or elevated liver enzymes were recorded. Conclusions. MMF is a safe therapeutic modality which failed to show a beneficial effect both in functional and radiological parameters in a small cohort of IPF patients.

Abstract
This study aims to determine the effectiveness of mycophenolate sodium (MS) in patients with scleroderma (SSc)-related interstitial lung disease (ILD). In a prospective observational study, we evaluated 14 consecutive SSc-ILD patients who were treated with MS for 12 months. The effect of MS on lung function was examined by using longitudinal data analytic methods. Wilcoxon rank-sum tests were used to examine the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and diffusing capacity of the lung for carbon monoxide (DLCO) by pulmonary function testing. As a group, the median values for FVC, FEV1 and DLCO did not change significantly after 12 months of MS therapy and fulfilled the definition of stable disease by the American Thoracic Society. Individually, after 12 months of treatment, 6 out of 14 patients showed a pulmonary improvement defined as an increase of more than 10% in FVC, and 5 out of 14 patients remained stable. By contrast, the median FVC had declined a non-significant 7.2% from the previous 12 months before MS initiation. No significant drug adverse effects were registered. These prospective data suggest that MS is a safe and well-tolerated therapy for SSc-ILD patients, and it is capable of preventing functional pulmonary deterioration.

Abstract
BACKGROUND Cyclophosphamide (CYC) stabilizes the parameters of lung function tests (LFT) of patients with (SSc) and interstitial lung disease (ILD) treated for 12 months. There is little information about long-term treatment (24 months). The aim of this study is to analyze the effect of intravenous CYC in LFT parameters in patients with SSc and ILD treated for 24 months. PATIENTS AND METHOD Retrospective study of 37 patients with ILD associated with scleroderma treated with intravenous CYC for 24 months and regularly assessed by LFT (at baseline, 6, 12 and 24 months) including forced vital capacity (FVC) and transfer capacity of carbon monoxide (DL(CO)). To evaluate response to treatment the recommendations of the ATS and SEPAR were considered. RESULTS The difference between FVC and DL(CO) values performed at baseline and those performed at 6, 12, and 24 months were less than 10%, which meant that CYC stabilized LFT. There were no differences in LFT when patients treated for 6 months were evaluated according to the type of skin involvement of the SSc (diffuse or limited) and the duration of the ILD. Although patients with severe restriction (FVC<70%) showed more improvement, it was less than 10% in all cases. CONCLUSION In this series of patients with ILD associated with SSc intravenous CYC was effective in stabilizing LFT in long-term treatment.
