Abstract
Background and objectives The extent and pattern of radiological features (e.g. fibrosis and ground glass) can influence treatment approaches for systemic sclerosis-related interstitial lung disease (SSc-ILD). However, the pathobiology underlying these radiological features is poorly understood and warrants further investigation. Methods 68 proteins were measured in bronchoalveolar lavage (BAL) fluid from 103 SSc-ILD participants in Scleroderma Lung Study I. Quantitative image analysis calculated the extent of fibrosis (QLF) and ground-glass opacity (QGG) from concurrent high-resolution computed tomography (HRCT) scans. The relationship between BAL proteins and quantitative HRCT scores was assessed by univariate and multivariate analyses. Results QLF scores correlated weakly with the extent of QGG, suggesting two distinct processes. In a univariate analysis, 25 proteins from several biological pathways correlated with QLF scores, including profibrotic factors, tissue remodelling proteins, proteins involved in monocyte/macrophage migration and activation, and proteins linked to inflammation and immune regulation. In contrast, QGG scores correlated with only six proteins, of which four were unique and related to granulocyte activation, mobilisation of bone marrow mesenchymal stem cells and activation of T-cells, B-cells, macrophages and eosinophils. In the multivariate models, interleukin-4, CCL7, receptor activator of nuclear factor-κB and tumour necrosis factor-α were independently associated with QLF, whereas interferon-γ was independently associated with QGG. Interpretation QLF and QGG represent distinct radiological features of SSc-ILD, a conclusion reinforced by the presence of different biological pathways present within BAL fluid that associate with each. The identified proteins and related biological pathways may represent important therapeutic targets.

Abstract
Systemic sclerosis (SSc) is a rare autoimmune disease characterized by a tripod combining vasculopathy, fibrosis, and immune-mediated inflammatory processes. The prevalence of interstitial lung disease (ILD) in SSc varies according to the methods used to detect it, ranging from 25 to 95%. The fibrotic and vascular pulmonary manifestations of SSc, particularly ILD, are the main causes of morbidity and mortality, contributing to 35% of deaths. Although early trials were conducted with cyclophosphamide, more recent randomized controlled trials have been performed to assess the efficacy and tolerability of several medications, mostly mycophenolate, rituximab, tocilizumab, and nintedanib. Although many uncertainties remain, expert consensus is emerging to optimize the therapeutic management and to provide clinicians with evidence-based clinical practice guidelines for patients with SSc-ILD. This article provides an overview, in the light of the latest advances, of the available evidence for the diagnosis and management of SSc-ILD.

Abstract
Systemic sclerosis (SSc) is an autoimmune disease associated to fibrotic manifestations. Interstitial lung disease (SSc-ILD), one of the main fibrotic features of SSc, is the first cause of SSc-related death. The management of SSc-ILD has recently benefited from the results of key randomised controlled trials. French authorities have approved Nintedanib for the treatment of SSc-ILD, and tocilizumab has recently been approved by the Food and Drug Administration (FDA) in the United-States (US). These recent approvals challenge the management of this fibrotic manifestation of SSc. This narrative literature review, at the crossroad of internal medicine and pulmonology, discusses what could be an up-to date approach, in terms of diagnostic and therapeutic strategies for SSc-ILD, in the light of the results from recent clinical trials.

Abstract
OBJECTIVES Cyclophosphamide (CYC) has been proposed as a standard induction regimen for interstitial lung disease (ILD) associated with systemic sclerosis (SSc). However, there remain patients with SSc-ILD who are intractable to the therapy. This study aimed to identify factors associated with inadequate response to CYC and investigate how to treat SSc-ILD, especially in the need for glucocorticoids (GCs) combined with CYC. METHODS This retrospective study included consecutive patients diagnosed with SSc-ILD and treated with CYC between 2009 and 2020. Logistic regression models were used to determine the prognostic factors indicating significant progression of ILD (SP-ILD). The clinical findings of patients treated with vs. without GCs were compared. RESULTS Nineteen patients were registered, with a median age of 61.0 years. Fifteen were females, and five were classified into SP-ILD. Baseline high C-reactive protein (CRP) levels and non-widespread or localized ground-glass opacities (GGOs) predicted SP-ILD in multivariable analyses, and the cut-off level of CRP was 0.41 mg/dL. In clinical courses, SSc-ILD with high inflammation temporarily responded to CYC, regardless of the combined use of GCs; however, the therapeutic effects deteriorated soon after stopping CYC. CONCLUSION High CRP levels with non-widespread GGO predicted progressive ILD in patients with SSc treated with CYC.

Abstract
Bronchoalveolar lavage and lung biopsy (LBx) are helpful in patients with connective tissue diseases (CTD) and interstitial lung diseases (ILD) regardless of cause, including infectious, noninfectious, immunologic, or malignant. The decision whether to perform only bronchoalveolar lavage (BAL), and eventually a subsequent LBx in case of a nondiagnostic lavage, or one single bronchoscopy combining both sampling methods depends on the clinical suspicion, on patient’s characteristics (e.g. increased biopsy risk) and preferences, and on the resources and biopsy techniques available locally (e.g. regular forceps versus cryobiopsy). In CTD-ILD, BAL has major clinical utility in excluding infections and in the diagnosis of specific patterns of acute lung damage (e.g. alveolar hemorrhage, diffuse alveolar damage, and organizing pneumonia). LBx is indicated to exclude neoplasm or diagnose lymphoproliferative lung disorders that in CTD patients are more common than in the general population. Defining BAL cellularity and characterizing the CTD-ILD histopathologic pattern by LBx can be helpful in the differential diagnosis of cases without established CTD [e.g. ILD preceding full-blown CTD, interstitial pneumonia with autoimmune features (IPAF)], but the prognostic and theragnostic role of those findings remains unclear. Few studies in the pretranscriptomics era have investigated the diagnostic and prognostic role of BAL and LBx in CTD-ILD, and it is reasonable to hypothesize that future studies conducted applying innovative techniques on BAL and LBx might open new and unexpected avenues in pathogenesis, diagnosis, and treatment approach to CTD-ILD. This is particularly desirable now that a new drug treatment era is emerging, in which we have more than one therapeutic choice (immunosuppressive agents, antifibrotic drugs, and biological agents). We hope that future research will pave the path toward precision medicine providing data for a more accurate ILD-CTD endotyping that will guide the physicians through targeted therapeutic choices, rather than to the approximative approach ‘one drug fits them all’.

Abstract
Many therapies have been investigated for systemic sclerosis-associated interstitial lung disease (SSc-ILD), including immunosuppressive therapies, antifibrotic agents, immunomodulators and monoclonal antibodies. There is a high unmet medical need to better understand the current evidence for treatment efficacy and safety. This systematic review aims to present the existing literature on different drug treatments investigated for SSc-ILD and to critically assess the level of evidence for these drugs. A systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A structured literature search was performed for clinical trials and observational studies on the treatment of SSc-ILD with pharmaceutical interventions from 1 January 1990 to 15 December 2020. The quality of each reference was assessed using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria. A total of 77 references were reviewed and 13 different treatments were identified. We found high-quality evidence for the use of cyclophosphamide, nintedanib, mycophenolate and tocilizumab. Therefore, we would posit that the clinical community has four valid options for treatment of SSc-ILD. Further research is mandatory to provide more evidence for the optimal treatment strategy in SSc-ILD, including the optimal time to initiate treatment, selection of patients for treatment and upfront combination therapy.

Abstract
Background The utility of bronchoalveolar lavage (BAL) in the evaluation of systemic sclerosis-associated interstitial lung disease (SSc-ILD) remains controversial. Fractional analysis of BAL (FBAL) is a technique that can analyze small airways and alveolar compartments separately and has proven informative in other ILDs. The aim of this study was to explore FBAL characteristics across the spectrum of SSc-ILD severity. Methods We retrospectively reviewed patients with SSc-ILD who underwent bronchoscopy with FBAL using three 50 mL aliquots of saline solution. These aliquots were analyzed separately for differential cell composition (FBAL-1, -2, and -3). We compared the FBAL cell composition to the progression of ILD and end-stages of ILD using Cox proportional hazards models. Results Sixty-eight patients with SSc-ILD were enrolled in this study. The percentage of neutrophils and eosinophils was lower in FBAL-3 compared to FBAL-1. In contrast, the percentage of macrophages and lymphocytes was higher in FBAL-3. Neutrophils in FBAL-2, -3, and the estimated total FBAL cell fraction (FBAL-total) were negatively correlated with the forced vital capacity % predicted (r=−0.420, −0.362, −0.409, respectively). Although FBAL-total was not linked to the progression and end-stage of ILD, a high percentage of neutrophils in FBAL-3 was significantly associated with the development of end-stage ILD (HR 1.093, 95% CI: 1.003–1.190). Conclusions A higher percentage of neutrophils in FBAL-3 is correlated with development of end-stage ILD in SSc-ILD as well as mortality.

Abstract
OBJECTIVES To compare the effectiveness of cyclophosphamide and rituximab in the treatment of patients with systemic sclerosis with pulmonary involvement (SSc-ILD). METHODS Symptoms and the respiratory function parameters of 34 patients receiving cyclophosphamide and 27 patients receiving rituximab for at least 24 months between 1996 and 2018 were compared. RESULTS It was observed that symptoms including cough, Raynaud's phenomenon, digital ulceration, diarrhea, and dysphagia, but not dyspnea, recovered statistically significantly more in the rituximab group (p = 0.004, p = 0.001, p = 0.006, p = 0.005, and p < 0.001, respectively; for dyspnea p = 0.11). When differences in FVC and FVC% values were compared with baseline, it was found that there was a statistically significant increase in FVC (mL) (p = 0.02) and FVC% (p = 0.002) values after 12 months of treatment in patients receiving cyclophosphamide compared with those receiving rituximab. When differences in DLCO and DLCO% values from baseline were compared, a statistically significant increase was seen in DLCO values after 15 and 24 months (p = 0.003 and p = 0.048, respectively) of treatment, also in DLCO% values after 15 and 18 months (p = 0.008 and p = 0.01, respectively) of treatment in patients receiving rituximab compared with those receiving cyclophosphamide. CONCLUSION It was observed that both cyclophosphamide and rituximab treatments were effective in controlling dyspnea and worsened pulmonary function in SSc-ILD. The effect of cyclophosphamide is more prominent on FVC and rituximab is more effective on DLCO. Key Points • Both cyclophosphamide and rituximab treatments were effective in controlling dyspnea and worsened pulmonary function in SSc-ILD. • The effect of cyclophosphamide is more prominent on FVC and rituximab is more effective on DLCO.

Abstract
Children with rheumatic disease have rare pulmonary manifestations that may cause significant morbidity and mortality. These children are often clinically asymptomatic until disease has significantly progressed, so they should be screened for pulmonary involvement. There has been recent recognition of a high mortality-related lung disease in systemic-onset juvenile idiopathic arthritis; risk factors include onset of juvenile idiopathic arthritis less than 2 years of age, history of macrophage activation syndrome, presence of trisomy 21, and history of anaphylactic reaction to biologic therapy. Early recognition and treatment of lung disease in children with rheumatic diseases may improve outcomes.

Abstract
INTRODUCTION We performed a systematic review of the literature to determine the value of bronchoalveolar lavage (BAL) in evaluating the pulmonary involvement of systemic sclerosis (SSc). METHODS Articles published between 1980 and 2019 were retrieved from the databases: PubMed and Scielo. The search was restricted to clinical trials published in English, utilizing the keywords "scleroderma, systemic sclerosis, interstitial lung disease, and bronchoalveolar lavage". RESULTS Twenty-two papers were analyzed. A positive correlation was observed between increased BAL cellularity (alveolitis) and worsening clinical symptoms, pulmonary function, and radiological pattern in 2, 11, and 15 studies, respectively. The majority of BAL studies that evaluated interleukin levels, including TNF-α, IL-6, IL-7, and IL-8, observed higher levels in patients with impaired pulmonary function and increased lung involvement. CONCLUSIONS Alveolitis and the increase of some cytokines/chemokines in BAL were related to more severe pulmonary disease in SSc in the majority of the studies and seemed to be markers of worse prognosis, but it is unknown whether BAL adds clinical value to the use of the other non-invasive diagnostic procedures.

Abstract
Systemic sclerosis (SSc) is a complex, multiorgan, autoimmune disease. Lung fibrosis occurs in ∼80% of patients with SSc; 25% to 30% develop progressive interstitial lung disease (ILD). The pathogenesis of fibrosis in SSc-associated ILD (SSc-ILD) involves cellular injury, activation/differentiation of mesenchymal cells, and morphological/biological changes in epithelial/endothelial cells. Risk factors for progressive SSc-ILD include older age, male sex, degree of lung involvement on baseline high-resolution computed tomography imaging, reduced DlCO, and reduced FVC. SSc-ILD does not share the genetic risk architecture observed in idiopathic pulmonary fibrosis (IPF), with key risk factors yet to be identified. Presence of anti-Scl-70 antibodies and absence of anti-centromere antibodies indicate increased likelihood of progressive ILD. Elevated levels of serum Krebs von den Lungen-6 and C-reactive protein are both associated with SSc-ILD severity and predict SSc-ILD progression. A promising prognostic indicator is serum chemokine (C-C motif) ligand 18. SSc-ILD shares similarities with IPF, although clear differences exist. Histologically, a nonspecific interstitial pneumonia pattern is commonly observed in SSc-ILD, whereas IPF is defined by usual interstitial pneumonia. The course of SSc-ILD is variable, ranging from minor, stable disease to a progressive course, whereas all patients with IPF experience progression of disease. Although appropriately treated patients with SSc-ILD have better chances of stabilization and survival, a relentlessly progressive course, akin to IPF, is seen in a minority. Better understanding of cellular and molecular pathogenesis, genetic risk, and distinctive features of SSc-ILD and identification of robust prognostic biomarkers are needed for optimal disease management.

Abstract
Systemic sclerosis is an autoimmune connective tissue disease, which is characterised by immune dysregulation and progressive fibrosis that typically affects the skin, with variable internal organ involvement. It is a rare condition that affects mostly young and middle-aged women, resulting in disproportionate morbidity and mortality. Currently, interstitial lung disease is the most common cause of death among patients with systemic sclerosis, with a prevalence of up to 30% and a 10-year mortality of up to 40%. Interstitial lung disease is more common among African Americans and in people with the diffuse cutaneous form of systemic sclerosis or anti-topoisomerase 1 antibodies. Systemic sclerosis-associated interstitial lung disease most commonly presents with dyspnoea, cough, and a non-specific interstitial pneumonia pattern on CT scan, with a minority of cases fulfilling the criteria for usual interstitial pneumonia. The standard therapy has traditionally been combinations of immunosuppressants, particularly mycophenolate mofetil or cyclophosphamide. These immunosuppressants can be supplemented by targeted biological and antifibrotic therapies, whereas autologous haematopoietic stem-cell transplantation and lung transplantation are reserved for refractory cases.

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
Objective To identify serum cytokines which predict mortality and/or disease progression in patients with systemic sclerosis, especially with pulmonary involvement. Methods Serum cytokines (IL-6, IL-7, IL-8, IL-10, CCL2, CCL4, TGF-β, TNF-α) were measured in 125 SSc patients, who were recruited and observed in our outpatient clinic. Of these, 60 had pulmonary involvement, classified as either interstitial lung disease (ILD, 43 patients), pulmonary arterial hypertension (PAH, 7 patients) or pulmonary hypertension and ILD (PH-ILD, 10 patients). The association of serum cytokines with clinical features was analysed and their correlation with BAL cytokines measured in a subset of SSc patients with ILD. Results Serum cytokines were detected at different levels: high (TGF-β, median 287.5 pg/ml; CCL2, median 89.7 pg/ml; CCL4, median 104.2 pg/ml), low (IL-6, median 3.2 pg/ml; IL-7 median 2.3 pg/ml; IL-8, median 5.2 pg/ml; TNF-α, median 0 pg/ml but with a bimodal distribution) and very low (IL-10, median 0.4 pg/ml). IL-6 and IL-7 were predictive for death in a Cox regression analysis in all SSc patients as well as in all patients with pulmonary involvement; IL-6 was predictive for mortality in SSc-ILD patients. In a multivariate analysis, cytokine levels could also predict a change in lung function, e.g. IL-7 was a predictor for a decline of diffusion capacity (DLCO) by 20 or 30% in ILD patients. In a subset of ILD patients, serum cytokines were compared to BAL cytokines, but revealed only few correlations. Conclusion In conclusion, the analysis of serum cytokines implicates a role as biomarkers, distinct from BAL.

Abstract
INTRODUCTION Interstitial lung disease (ILD) is the most common cause of mortality in systemic sclerosis; accounting for approximately 35% of deaths. Although immunosuppression is currently opted as first line therapy for scleroderma-related ILD (SSc-ILD), the benefits from it remain modest with concerns for systemic toxicity from long term use. Areas covered: We review the important facets in monitoring a patient with SSc-ILD, including recognizing various patterns of ILD, identifying those at risk for disease progression and discuss the strength of evidence for immunosuppressant drugs and lung transplantation. We also discuss the potential role of anti-fibrotic agents and the existing evidence for myeloablative stem-cell transplantation. Expert commentary: Non-specific interstitial pneumonia (NSIP) is the most common radiologic and histopathologic pattern seen, but other forms of ILD may also be appreciated. Mycophenolate mofetil and cyclophosphamide are most commonly used as first line therapy for SSc-ILD; however, the efficacy of mycophenolate is comparable to cyclophosphamide with a better tolerability profile. Selected patients with SSc-ILD may be candidates for lung transplantation, although meticulous assessment for co-morbidities is crucial. Further studies are required to deduce the role of anti-fibrotic medications, biologic agents and effects of myeloablative stem cell transplantation in SSc.

Abstract
Interstitial lung disease (ILD) is the primary cause of death in patients with systemic sclerosis (SSc). It is thought that chronic inflammation is a key component in SSc-ILD. Treatment, such as cyclophosphamide (CYC), targets this inflammation. We hypothesized that treatment with CYC might be more effective in the inflammatory phase. Therefore, we analyzed whether the extent of inflammation, as assessed by the proportion of ground glass compared to fibrosis, SSc disease duration, the extent of ILD, or baseline diffusion capacity of the lungs (DLCO) < 60%, modifies the effect of intravenous CYC pulse therapy (750 mg/m2) on pulmonary function (as measured by FVC, DLCO) in SSc-ILD patients, after 12, 24, and 36 months. Consecutive patients with SSc-ILD receiving CYC pulses between 2003 and 2015 were included. Pulmonary function tests were performed at 0, 6, 12, 24, and 36 months. There were 75 patients included. Forced vital capacity (FVC) (86% of predicted) and DLCO (42% of predicted) were stable after 12, 24 and 36 months of follow-up (p > 0.05). Forty-four patients completed 12 cycles of CYC. For the extent of ILD, proportion of ground glass compared to fibrosis, SSc disease duration, and baseline DLCO, there were no differences (all p > 0.05) in the course of FVC and DLCO. Treatment with CYC followed by maintenance therapy stabilizes pulmonary function in patients with SSc-ILD over a 3-year period. The extent of ILD, proportion of ground glass, SSc disease duration, and baseline DLCO < 60% did not influence the effect of CYC on pulmonary function.

Abstract
Interstitial lung disease (ILD) is the leading cause of morbidity and mortality in systemic sclerosis (SSc). We performed a systematic review to characterise the use and validation of pulmonary function tests (PFTs) as surrogate markers for systemic sclerosis-associated interstitial lung disease (SSc-ILD) progression.Five electronic databases were searched to identify all relevant studies. Included studies either used at least one PFT measure as a longitudinal outcome for SSc-ILD progression (i.e. outcome studies) and/or reported at least one classical measure of validity for the PFTs in SSc-ILD (i.e. validation studies).This systematic review included 169 outcome studies and 50 validation studies. Diffusing capacity of the lung for carbon monoxide (DLCO) was cumulatively the most commonly used outcome until 2010 when it was surpassed by forced vital capacity (FVC). FVC (% predicted) was the primary endpoint in 70.4% of studies, compared to 11.3% for % predicted DLCO Only five studies specifically aimed to validate the PFTs: two concluded that DLCO was the best measure of SSc-ILD extent, while the others did not favour any PFT. These studies also showed respectable validity measures for total lung capacity (TLC).Despite the current preference for FVC, available evidence suggests that DLCO and TLC should not yet be discounted as potential surrogate markers for SSc-ILD progression.

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
BACKGROUND Approximately one-third of individuals with interstitial lung disease (ILD) have associated connective tissue disease (CTD). The connective tissue disorders most commonly associated with ILD include scleroderma/systemic sclerosis (SSc), rheumatoid arthritis, polymyositis/dermatomyositis, and Sjögren's syndrome. Although many people with CTD-ILD do not develop progressive lung disease, a significant proportion do progress, leading to reduced physical function, decreased quality of life, and death. ILD is now the major cause of death amongst individuals with systemic sclerosis.Cyclophosphamide is a highly potent immunosuppressant that has demonstrated efficacy in inducing and maintaining remission in autoimmune and inflammatory illnesses. However this comes with potential toxicities, including nausea, haemorrhagic cystitis, bladder cancer, bone marrow suppression, increased risk of opportunistic infections, and haematological and solid organ malignancies.Decision-making in the treatment of individuals with CTD-ILD is difficult; the clinician needs to identify those who will develop progressive disease, and to weigh up the balance between a high level of need for therapy in a severely unwell patient population against the potential for adverse effects from highly toxic therapy, for which only relatively limited data on efficacy can be found. Similarly, it is not clear whether histological subtype, disease duration, or disease extent can be used to predict treatment responsiveness. OBJECTIVES To assess the efficacy and adverse effects of cyclophosphamide in the treatment of individuals with CTD-ILD. SEARCH METHODS We performed searches on CENTRAL, MEDLINE, Embase, CINAHL, and Web of Science up to May 2017. We handsearched review articles, clinical trial registries, and reference lists of retrieved articles. SELECTION CRITERIA We included randomised controlled parallel-group trials that compared cyclophosphamide in any form, used individually or concomitantly with other immunomodulating therapies, versus non-cyclophosphamide-containing therapies for at least six months, with follow-up of at least 12 months from the start of treatment. DATA COLLECTION AND ANALYSIS We imported studies identified by the search into a reference manager database. We retrieved the full-text versions of relevant studies, and two review authors independently extracted data. Primary outcomes were change in lung function (change in forced vital capacity (FVC) % predicted and diffusing capacity of the lung for carbon monoxide (DLCO) % predicted), adverse events, and health-related quality of life measures. Secondary outcomes included all-cause mortality, dyspnoea, cough, and functional exercise testing. When appropriate, we performed meta-analyses and subgroup analyses by severity of lung function, connective tissue disease diagnosis, and radiological pattern of fibrosis. We assessed the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach and created 'Summary of findings' tables. MAIN RESULTS We included in the analysis four trials with 495 participants (most with systemic sclerosis). We formed two separate comparisons: cyclophosphamide versus placebo (two trials, 195 participants) and cyclophosphamide versus mycophenolate (two trials, 300 participants). We found evidence to be of low quality, as dropout rates were high in the intervention groups, and as we noted a wide confidence interval around the effect with small differences, which affected the precision of results.The data demonstrates significant improvement in lung function with cyclophosphamide compared with placebo (post-treatment FVC % mean difference (MD) 2.83, 95% confidence interval (CI) 0.80 to 4.87; P = 0.006) but no significant difference in post-treatment DLCO (% MD -1.68, 95% CI -4.37 to 1.02; P = 0.22; two trials, 182 participants).Risk of adverse effects was increased in the cyclophosphamide treatment groups compared with the placebo groups, in particular, haematuria, leukopenia, and nausea, leading to a higher rate of withdrawal from cyclophosphamide treatment. The data demonstrates statistically significant improvement in one-measure of quality of life in one trial favouring cyclophosphamide over placebo and clinically and statistically significant improvement in breathlessness in one trial favouring cyclophosphamide compared with placebo, with no significant impact on mortality.Trialists reported no significant impact on lung function when cyclophosphamide was used compared with mycophenolate at 12 months (FVC % MD -0.82, 95% CI -3.95 to 2.31; P = 0.61; two trials, 149 participants; DLCO % MD -1.41, 95% CI -10.40 to 7.58; P = 0.76; two trials, 149 participants).Risk of side effects was increased with cyclophosphamide versus mycophenolate, in particular, leukopenia and thrombocytopenia.The data demonstrates no significant impact on health-related quality of life, all-cause mortality, dyspnoea, or cough severity in the cyclophosphamide group compared with the mycophenolate group. No trials reported outcomes associated with functional exercise tests.We performed subgroup analysis to determine whether severity of lung function, connective tissue disease diagnosis, or radiological pattern had any impact on outcomes. One trial reported that cyclophosphamide protected against decreased FVC in individuals with worse fibrosis scores, and also showed that cyclophosphamide may be more effective in those with worse lung function. No association could be made between connective tissue disease diagnosis and outcomes. AUTHORS' CONCLUSIONS This review, which is based on studies of varying methodological quality, demonstrates that overall, in this population, small benefit may be derived from the use of cyclophosphamide in terms of mean difference in % FVC when compared with placebo, but not of the difference in % DLCO, or when compared with mycophenolate. Modest clinical improvement in dyspnoea may be noted with the use of cyclophosphamide. Clinical practice guidelines should advise clinicians to consider individual patient characteristics and to expect only modest benefit at best in preserving FVC. Clinicians should carefully monitor for adverse effects during treatment and in the years thereafter.Further studies are required to examine the use of cyclophosphamide; they should be adequately powered to compare outcomes within different subgroups, specifically, stratified for extent of pulmonary infiltrates on high-resolution computed tomography (HRCT) and skin involvement in SSc. Studies on other forms of connective tissue disease are needed. Researchers may consider comparing cyclophosphamide (a potent immunosuppressant) versus antifibrotic agents, or comparing both versus placebo, in particular, for those with evidence of rapidly progressive fibrotic disease, who may benefit the most.

Abstract
Although interstitial lung disease accounts for the majority of deaths of patients with systemic sclerosis, treatment options for this manifestation of the disease are limited. Few high-quality, randomized, controlled trials exist for systemic sclerosis-related interstitial lung disease, and historically, studies have favored the use of cyclophosphamide. However, the benefit of cyclophosphamide for this disease is tempered by its complex adverse event profile. More recent studies have demonstrated the effectiveness of mycophenolate for systemic sclerosis-related interstitial lung disease, including Scleroderma Lung Study II. This review highlights the findings of this study, which was the first randomized controlled trial to compare cyclophosphamide with mycophenolate for the treatment of systemic sclerosis-related interstitial lung disease. The results reported in this trial suggest that there is no difference in treatment efficacy between mycophenolate and cyclophosphamide; however, mycophenolate appears to be safer and more tolerable than cyclophosphamide. In light of the ongoing advances in our understanding of the pathogenic mechanisms underlying interstitial lung disease in systemic sclerosis, this review also summarizes novel treatment approaches, presenting clinical and preclinical evidence for rituximab, tocilizumab, pirfenidone, and nintedanib, as well as hematopoietic stem cell transplantation and lung transplantation. This review further explores how reaching a consensus on appropriate study end points, as well as trial enrichment criteria, is central to improving our ability to judiciously evaluate the safety and efficacy of emerging experimental therapies for systemic sclerosis-related interstitial lung disease.

Abstract
Scleroderma (systemic sclerosis) is an autoimmune rheumatic disorder that is characterized by fibrosis, vascular dysfunction, and autoantibody production that involves most visceral organs. It is characterized by a high morbidity and mortality rate, mainly due to disease-related complications. Epidemiological data describing mortality and survival in this population have been based on both population and observational studies. Multiple clinical and non-clinical factors have been found to predict higher likelihood of death among thepatients. Here, we do an extensive review of the available literature, utilizing the PubMed database, to describe scleroderma and non-scleroderma related determinants of mortality in this population. We found that even though the mortality among the general population has declined, scleroderma continues to carry a very high morbidity and mortality rate, however we have made some slow progress in improving the mortality among scleroderma patients over the last few decades.

Abstract
Pulmonary involvement during systemic sclerosis (SS) is dominated by interstitial lung disease and arterial pulmonary hypertension. It is about a retrospective study analyzing 65 cases of SS over a period of 13 years. We compared cases with and without interstitial lung disease. The diagnosis of SS was retained according to American College of Rheumatology (ACR)/EULAR 2013 criteria. The diagnosis of interstitial lung disease was retained in TDM and EFR. Pulmonary hypertension is defined by a pulmonary arterial pression higher than 25 mmHg. The mean delay of diagnosis of interstitial lung disease and the diagnosis was of 48 months (extremes 0-78 months). The comparison between both groups according to average age of the patients, prevalence of pulmonary hypertension, frequency of Raynaud phenomenon and trophic disorders did not find any significant difference. Lung involvement was associated with an esophageal involvement in 71% of the cases (P=0.059). Antibodies anti-Scl 70 were noted more frequently in patient's with interstitial lung disease (79% of the cases, P=0.001). Patients were treated with colchicine and vitamin E. A corticotherapy had been indicated at a single patient. The evolution of SS was marked by the stabilisation of the restrictive syndrome in 71.8% of the cases and a worsening in 25% of the cases. Early and appropriate diagnosis of SS and screening of lung involvement are essential for a early care.

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
Systemic sclerosis (SSc, or scleroderma) is a rheumatic disease with distinct features that encompass autoimmunity, vascular lesions (vasculopathy) and tissue fibrosis. The disease has a high morbidity and mortality compared with other rheumatic diseases. This review discusses risk factors and markers that predict the disease course and the occurrence of disease manifestations, with an emphasis on major organ involvement. In addition, risk factors will be described that are associated with mortality in SSc patients. The review addresses the impact of recent developments on screening, diagnosis and risk stratification as well as the need for further research where data are lacking.

Abstract
Inflammation in systemic sclerosis (SSc) is a prominent, but incompletely characterized feature in early stages of the disease. The goal of these studies was to determine the circulating levels, clinical correlates and biological effects of the acute phase protein serum amyloid A (SAA), a marker of inflammation, in patients with SSc. Circulating levels of SAA were determined by multiplex assays in serum from 129 SSc patients and 98 healthy controls. Correlations between SAA levels and clinical and laboratory features of disease were analyzed. The effects of SAA on human pulmonary fibroblasts were studied ex vivo. Elevated levels of SAA were found in 25% of SSc patients, with the highest levels in those with early-stage disease and diffuse cutaneous involvement. Significant negative correlations of SAA were found with forced vital capacity and diffusion capacity for carbon monoxide. Patients with elevated SAA had greater dyspnea and more frequent interstitial lung disease, and had worse scores on patient-reported outcome measures. Incubation with recombinant SAA induced dose-dependent stimulation of IL-6 and IL-8 in normal lung fibroblasts in culture. Serum levels of the inflammatory marker SAA are elevated in patients with early diffuse cutaneous SSc, and correlate with pulmonary involvement. In lung fibroblasts, SAA acts as a direct stimulus for increased cytokine production. These findings suggest that systemic inflammation in SSc may be linked to lung involvement and SAA could serve as a potential biomarker for this complication.

Abstract
Interstitial lung disease (ILD) is becoming one of the main causes of death of patients with systemic sclerosis (SSc). The prevalence of ILD associated with SSc (SSc-ILD) varies from 33% to 100% according to diagnostic methods. Clinical features such as dyspnea on exertion, dry cough, and chest pains are not specific and usually late-appearing, implying more specific tests in the diagnostic, prognosis, and follow-up of ILD in patients with SSc. High resolution thoracic CT scanner (HRCT) is more sensitive than chest X-ray in the detection of SSc-ILD. Pulmonary function tests (PFT) are non-invasive and periodically used to assess the impacts of SSc on respiratory function. Diagnostic values of bronchoalveolar lavage and histological examination on lung biopsy are controversial. However, these techniques are essential for studying cellular and molecular mechanisms underlying the pathophysiology of SSc-ILD. Several biomarkers such as surfactant-A (SP-A), -D (SP-D), mucin-like high molecular weight glycoprotein (KL-6), and chemokine CCL-18 have been implicated in SSc-PID. Serum levels of these proteins are correlated with the severity of SSc-ILD, as assessed by HRCT and/or PFT. Finally, alveolar concentration of exhaled nitric oxide can be used to screen SSc patients with high risk of deterioration of respiratory function, in whom immunosuppressant treatment could be useful in preventing the evolution to irreversible lung fibrosis.

Abstract
BACKGROUND Interstitial lung disease (ILD) is the leading cause of morbidity and mortality in patients with systemic sclerosis (SSc); however, prognostication of SSc-associated ILD (SSc-ILD) remains challenging. We conducted a systematic review to identify variables that predict mortality and ILD progression in SSc-ILD. METHODS Three databases were searched to identify all studies relating to predictors of mortality or ILD progression in SSc-ILD. Studies were eligible if they were published in English and included ≥ 10 adults with SSc-ILD. Two authors independently reviewed and extracted data from acceptable studies. RESULTS The initial search identified 3,145 unique citations. Twenty-seven studies, including six abstracts, met the inclusion criteria. A total of 1,616 patients with SSc-ILD were included. Patient-specific, ILD-specific, and SSc-specific variables predicted mortality and progression; however, most predictors were identified in only one study. Most studies did not fully account for potential confounders, and none of the studies included a validation cohort. Older age, lower FVC, and lower diffusing capacity of carbon monoxide predicted mortality in more than one study. Male sex, extent of disease on high-resolution CT (HRCT) scan, presence of honeycombing, elevated KL-6 values, and increased alveolar epithelial permeability were identified as predictors of both mortality and ILD progression on unadjusted analysis. The extent of disease on HRCT scan was the only variable that independently predicted both mortality and ILD progression. CONCLUSIONS Mortality and ILD progression were predicted by several patient-specific, ILD-specific, and SSc-specific factors. Additional prospective studies are required to validate these preliminary findings and to identify combinations of variables that accurately predict the prognosis of SSc-ILD.

Abstract
Pulmonary complications are an important extra-articular feature of autoimmune rheumatic diseases and a major cause of mortality. The underlying pathogenesis probably involves multiple cellular compartments, including the epithelium, lung fibroblasts, and the innate and adaptive immune system. Heterogeneity in the extent and progression of lung fibrosis probably reflects differences in underlying pathogenic mechanisms. Growing understanding of the key pathogenic drivers of lung fibrosis might lead to the development of more effective targeted therapies to replicate the treatment advances in other aspects of these diseases. Interstitial lung disease (ILD) in connective tissue disease (CTD) is characterized using the classification of the idiopathic interstitial pneumonias. Systemic sclerosis is most frequently associated with ILD and, in most of these patients, ILD manifests as a histological pattern of nonspecific interstitial pneumonia. Conversely, in rheumatoid arthritis, the pattern of ILD is most often usual interstitial pneumonia. The key goals of clinical assessment of patients with both ILD and CTD are the detection of ILD and prognostic evaluation to determine which patients should be treated. Data from treatment trials in systemic sclerosis support the use of immunosuppressive therapy, with the treatment benefit largely relating to the prevention of progression of lung disease.

Abstract
Based on international collaborative data, interstitial lung disease is now the most frequent cause of death in systemic sclerosis (SSc), having supplanted renal crisis in that regard. Despite detailed explorations of candidate mediators, no primary pathway in the pathogenesis of interstitial lung disease associated with SSc (SSc-ILD) has been definitively identified and, therefore, treatment with current agents is only partially successful. However, as immunomodulatory agents do, on average, retard progression of lung disease, early identification of SSc-ILD, using thoracic high resolution computed tomography (HRCT), is highly desirable. The decision whether to introduce therapy immediately is often difficult as the balance of risk and benefit favours a strategy of careful observation when lung disease is very limited, especially in long-standing SSc. The threshold for initiating treatment is substantially reduced when lung disease is severe, systemic disease is short in duration or ongoing progression is evident, based on pulmonary function tests and symptoms. This review summarises epidemiology, pathogenesis, difficult clinical problems and management issues in SSc-ILD.

Abstract
BACKGROUND Patients with chronic known or unknown interstitial lung disease (ILD) may present with severe respiratory flares that require intensive management. Outcome data in these patients are scarce. PATIENTS AND METHODS Clinical and radiological features were collected in 83 patients with ILD-associated acute respiratory failure (ARF). Determinants of hospital mortality and response to corticosteroid therapy were identified by logistic regression. RESULTS Hospital and 1-year mortality rates were 41% and 54% respectively. Pulmonary hypertension, computed tomography (CT) fibrosis and acute kidney injury were independently associated with mortality (odds ratio (OR) 4.55; 95% confidence interval (95%CI) (1.20-17.33); OR, 7.68; (1.78-33.22) and OR 10.60; (2.25-49.97) respectively). Response to steroids was higher in patients with shorter time from hospital admission to corticosteroid therapy. Patients with fibrosis on CT had lower response to steroids (OR, 0.03; (0.005-0.21)). In mechanically ventilated patients, overdistension induced by high PEEP settings was associated with CT fibrosis and hospital mortality. CONCLUSION Mortality is high in ILD-associated ARF. CT and echocardiography are valuable prognostic tools. Prompt corticosteroid therapy may improve survival.

Abstract
Systemic sclerosis is a rare autoimmune condition that affects a variety of organ systems. Knowledge of the imaging features in this patient population is essential in facilitating accurate diagnosis and guiding treatment. Common and rare imaging features of systemic sclerosis are reviewed in this article. Skin, musculoskeletal, pulmonary, cardiac, gastrointestinal, renal, and oral imaging are discussed. Conventional radiography, computed tomography of the chest, echocardiography, enterography, scintigraphy, and panorex dental imaging are reviewed. In addition, the evolving applications of ultrasonography and magnetic resonance imaging to evaluate the musculoskeletal and cardiac features of systemic sclerosis are discussed.

Abstract
The connective tissue diseases (CTDs) are inflammatory, immune-mediated disorders in which interstitial lung disease (ILD) is common and clinically important. Interstitial lung disease may be the first manifestation of a CTD in a previously healthy patient. CTD-associated ILD frequently presents with the gradual onset of cough and dyspnea, although rarely may present with fulminant respiratory failure. Infection and drug reaction should always be ruled out. A diagnosis of idiopathic ILD should never be made without a careful search for subtle evidence of underlying CTD. Treatment of CTD-ILD typically includes corticosteroids and immunosuppressive agents.

Abstract
BACKGROUND Cough is a significant symptom in patients with scleroderma interstitial lung disease (SSc-ILD), affecting 73% of the 158 patients enrolled in the Scleroderma Lung Study (SLS), a multicenter randomized trial of oral cyclophosphamide (CYC) vs placebo (PLA) in patients with active interstitial lung disease. METHODS We examined the correlation of cough frequency and severity and phlegm production at baseline in 156 SLS participants with other baseline variables representing SSc-ILD disease activity and the cough response to 1 year of treatment with CYC vs PLA. RESULTS Patients with cough at baseline had significantly lower diffusing capacity of the lung for carbon monoxide, dyspnea, the quality-of-life physical component summary, and the maximal fibrosis score on high-resolution CT imaging compared with those without cough at baseline. Cough severity and frequency correlated with FVC % predicted. After 12 months of treatment, cough frequency decreased in the CYC group compared with the PLA group and was significantly different from the PLA group at 18 months (6 months after discontinuation of CYC). However, the decreases in cough frequency did not correlate with the changes in FVC or diffusing capacity of the lung for carbon monoxide observed in the CYC group. Treatment-related improvements in cough frequency, as well as in FVC, were no longer apparent 12 months after discontinuation of CYC. CONCLUSIONS Cough is a common symptom in SSc-ILD and correlates with the extent of fibrosis. Cough frequency decreases significantly in response to treatment with CYC but returns to baseline 1 year after withdrawal of treatment. Cough may be a symptom of ongoing fibrosis and an independent variable in assessing therapeutic response to CYC. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT000004563; URL: www.clinicaltrials.gov

Abstract
Some of the most pressing challenges associated with interstitial lung disease (ILD) are how best to define, diagnose, and treat connective tissue disease-associated ILD (CTD-ILD)--disorders with potentially substantial morbidity and mortality. In this focused review, we address aspects of prognosis for CTD-ILD and what indices might predict outcome, together with lessons that can be learnt from clinical trials of systemic sclerosis-associated ILD and idiopathic pulmonary fibrosis and how these lessons might be applied to future studies of CTD-ILD.

Abstract
The array of paediatric pulmonary complications of the various rheumatologic disorders illustrates both the complexities and challenges of the underlying disorders and the continuing lack of detailed knowledge of the pathophysiology and optimal treatment paradigms in children. While the vertical transfer of information has made much progress from adult studies, such as with the diagnosis and management of pulmonary arterial hypertension, in many instances underlying disorders may differ between children and adults in important and fundamental respects. Recognition of pulmonary complications of rheumatic disorders in children is often more difficult and requires anticipation and a high index of suspicion. Further progress in understanding and treating the various paediatric disorders is hampered by the lack of paediatric-specific information. Crucial to further progress are the expansion of orphan childhood disease databases and research networks. In this way a comprehensive approach to determining basic natural history, risks and outcomes, and defining the next generation of therapies in a disease-specific and age-specific manner can be achieved.

Are high doses of prednisone necessary for treatment of interstitial lung disease in systemic sclerosis? ACTA ACUST UNITED AC 2012; 8:58-62. [PMID: 22317852 DOI: 10.1016/j.reuma.2011.11.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2011] [Revised: 11/05/2011] [Accepted: 11/12/2011] [Indexed: 12/01/2022]
Abstract
INTRODUCTION Interstitial lung disease (ILD) as part of systemic sclerosis (SS) is a leading cause of morbidity and mortality. OBJECTIVES To evaluate the use of intravenous pulse cyclophosphamide combined with low and high doses of prednisone in the treatment of ILD in SS is equally effective. METHOD An experimental, exploratory and randomized single-blind clinical trial was conducted at Hermanos Ameijeiras Clinical Surgical Hospital from September 2006 to December 2009, including 23 patients with SS and ILD. Two treatment schedules were evaluated and randomly assigned. Group A was composed of 13 patients with a monthly dose of cyclophosphamide (ev) for 6 months and a twice-monthly dose for the remaining 6 months, prednisone (1 mg × kg × day) 4 weeks and then the dose was lowered to 5mg every 2 weeks up to 10mg. Group B: 10 patients with cyclophosphamide (ev), oral prednisone 10mg daily. RESULTS There are significant differences at onset of CVF and the honeycomb pattern between both groups, where the high dose group was at a disadvantage. At the end of treatment the low dose group achieved improvement of radiologic lesions and the Warrick index, unlike the high dose group. The remaining variables experienced improvement in both groups without marked inequality. Similarly, slight adverse reactions were present in both groups. Two patients dropped out of the study. CONCLUSIONS A combination of low dose steroids with cyclophosphamide is effective in interstitial lung disease treatment especially in active disease, and results did not showe differences regarding the high dose group but the sample size and the evolutionary severity of high dose patients oblige other studies to verify this data.

Abstract
OBJECTIVE To identify baseline characteristics of patients with scleroderma-related interstitial lung disease (SSc-ILD) that could serve as predictors of the most favorable response to 12-month treatment with oral cyclophosphamide (CYC). METHODS Regression analyses were retrospectively applied to the Scleroderma Lung Study data in order to identify baseline characteristics that correlated with the absolute change in forced vital capacity (FVC) (% predicted values) and the placebo-adjusted change in % predicted FVC over time (the CYC treatment effect). RESULTS Completion of the CYC arm of the Scleroderma Lung Study was associated with a placebo-adjusted improvement in the % predicted FVC of 2.11% at 12 months, which increased to 4.16% when patients were followed up for another 6 months (P=0.014). Multivariate regression analyses identified the maximal severity of reticular infiltrates (assessed as maximum fibrosis scores) on high-resolution computed tomography (HRCT) at baseline, the modified Rodnan skin thickness score (MRSS) at baseline, and the Mahler baseline dyspnea index as independent correlates of treatment response. When patients were stratified on the basis of whether 50% or more of any lung zone was involved by reticular infiltrates on HRCT and/or whether patients exhibited an MRSS of at least 23, a subgroup of patients emerged in whom there was an average CYC treatment effect of 9.81% at 18 months (P<0.001). Conversely, there was no treatment effect (a -0.58% difference) in patients with less severe HRCT findings and a lower MRSS at baseline. CONCLUSION A retrospective analysis of the Scleroderma Lung Study data identified the severity of reticular infiltrates on baseline HRCT and the baseline MRSS as patient features that might be predictive of responsiveness to CYC therapy.

Abstract
OBJECTIVE Patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD) are thought to have the greatest decline in lung function (forced vital capacity [FVC]% predicted) in the early years after disease onset. The aim of this study was to assess the natural history of the decline in FVC% predicted in patients receiving placebo in the Scleroderma Lung Study and to evaluate possible factors for cohort enrichment in future therapeutic trials. METHODS Patients randomized to receive placebo (n=79) were divided into 3 groups based on the duration of SSc (0-2 years, 2-4 years, and >4 years). Descriptive statistics and a mixed-effects model were used to analyze the rate of decline in the FVC% predicted over a 1-year period. Additional analyses stratified according to the severity of fibrosis on high-resolution computed tomography (HRCT) were performed, and interactions between disease severity and disease duration were explored. RESULTS The mean±SD decline in the unadjusted FVC% predicted during the 1-year period was 4.2±12.8%. At baseline, 28.5%, 43.0%, and 28.5% of patients were in the groups with disease durations of 0-2 years, 2-4 years, and >4 years, respectively. The rate of decline in the FVC% predicted was not significantly different across the 3 disease groups (P=0.85). When stratified by baseline fibrosis on HRCT, the rate of decline in the FVC% predicted was statistically significantly greater in the group with severe fibrosis (mean annualized decline in the FVC% predicted 7.2% versus 2.7% in the groups with no or moderate fibrosis; P=0.008). The decline observed in the group with severe fibrosis was most pronounced in those with a relatively short disease duration (0-2 years; annualized decline 7.0%). CONCLUSION Among patients with SSc-ILD in the Scleroderma Lung Study, the rates of progression of lung disease were similar irrespective of disease duration. The baseline HRCT fibrosis score is a predictor of a future decline in the FVC% predicted in the absence of effective treatment.
