Background:Systemic sclerosis (SSc) is a chronic autoimmune disease that carries significant mortality. Despite diagnostic and therapeutic advances in recent years, there is still a significant percentage of patients who do not present a complete clinical response, with the associated increase in morbidity and mortality. Specifically, pulmonary disease is frequent and entails a poor prognosis, with interstitial lung disease (ILD) and pulmonary hypertension (PAH) being the two most important complications, the first and second cause of mortality, respectively.Objectives:To evaluate the prevalence of ILD and/or PAH in patients affected by SSc and to determine the factors associated with ILD.Methods:Cross-sectional observational study of 102 patients diagnosed with SSc (Limited, Diffuse, SSc without scleroderma or Pre-scleroderma), treated between 1975 and 2020 at the Reina Sofia University Hospital in Cordoba. A descriptive study of the cohort was carried out and factors independently associated with ILD were evaluated using a multiple logistic regression model.Results:102 patients were included, 87.3% of these were female with an average age of 50.8 (14) years. There were 20 deaths (19.8%), from which 55% died because of SSc and the main reason was ILD and/or PAH. Respiratory complications (as ILD or as PAH) were present in 59 patients (57.8%), of whom 52 were diagnosed with ILD (90.4% with a pattern of non-specific interstitial pneumonia) and 25 PAH, whose mean pulmonary artery systolic pressure was 47.16 (18.54) mmHg. Anti-topoisomerase I antibodies were positive in 34.6% of patients who developed ILD, while anticentromere antibodies were more frequent in SSc without interstitial lung disease (80%). Independent factors associated with ILD were type of SSc, proximal skin involvement, anticentromere antibodies, current treatment with corticoids and the death.Conclusion:Just over half of the patients with SSc have lung disease (as ILD or as PAH). The main risk factors associated with ILD are proximal skin involvement and treatment with glucocorticoids, probably in the context of more severe forms that require more treatment. Anticentromere antibodies are more prevalent in patients with Limited SSc and their expression decreases the risk of developing ILD in these patients.References:[1]Orlandi M, Barsotti S, Lepri G, et al.

Clinical Profiles

Objective.To describe the clinical and serological features of systemic sclerosis sine scleroderma (ssSSc) in a multicentered SSc cohort.Methods.Data from 1417 subjects in the Canadian Scleroderma Research Group registry were extracted to identify subjects with ssSSc, defined as SSc diagnosed by an expert rheumatologist, but without any sclerodactyly or skin involvement prior to baseline study visit or during followup. Clinical and serological features of ssSSc subjects were compared to limited (lcSSc) and diffuse cutaneous SSc (dcSSc) subjects.Results.At the first registry visit, only 57 subjects (4.0%) were identified as having ssSSc. Of these, 30 (2.1%) were reclassified as lcSSc within 1.9 years. Thus, only 27 ssSSc subjects (1.9%) remained, with mean followup of 2.4 years. Clinical profiles of ssSSc were generally similar or milder compared to lcSSc, and milder than dcSSc, including rates of interstitial lung disease (25.9% ssSSc, 25.4% lcSSc, 40.3% dcSSc). Patients with ssSSc had serological profiles similar to those with lcSSc, including high rates of anticentromere antibodies (50.0% ssSSc, 47.5% lcSSc, 12.1% dcSSc), and low rates of antitopoisomerase I (16.7% ssSSc, 7.0% lcSSc, 21.8% dcSSc) and anti-RNA polymerase III (0 ssSSc, 11.1% lcSSc, 34.9% dcSSc).Conclusion.The condition ssSSc is rare and resembles lcSSc. These observations suggest that ssSSc is most likely a forme fruste of lcSSc, and that the absence of skin involvement may in part be related to misclassification arising from early or subtle skin involvement. There is little evidence to consider ssSSc as a distinct clinical or serological subset of SSc.

Objective:To identify target antigens of antifibroblast antibodies (AFA) in systemic sclerosis (SSc) patients.Patients and Methods:In the first part, sera from 24 SSc patients (12 with pulmonary arterial hypertension (PAH) and 12 without) and 36 idiopathic PAH patients, tested in pooled sera for groups of three, were compared with a sera pool from 14 healthy controls (HC). Serum IgG reactivity was analysed by the use of a two-dimensional electrophoresis and immunoblotting technique with normal human fibroblasts antigens. In the second part, serum IgG reactivity for two groups: 158 SSc, 67 idiopathic PAH and 100 HC; and 35 SSc and 50 HC was tested against α-enolase from Saccharomyces cerevisiae and recombinant human (rHu) α-enolase, respectively, on ELISA.Results:In the first part, α-enolase was identified as a main target antigen of AFA from SSc patients. In the second part, 37/158 (23%) SSc patients, 6/67 (9%) idiopathic PAH patients and 4/100 (4%) HC (p<0.001) had anti-S cerevisiae α-enolase antibodies; 12/35 (34%) SSc patients and 3/50 (6%) HC had anti-rHu α-enolase antibodies (p = 0.001). In SSc, the presence of anti-S cerevisiae α-enolase antibodies was associated with interstitial lung disease (ILD), decreased total lung capacity (73.2% vs 89.7%; p<0.001) and diffusion capacity for carbon monoxide (47.4% vs 62.3%; p<0.001), and antitopoisomerase 1 antibodies (46% vs 21%; p = 0.005) but not anticentromere antibodies (11% vs 34%; p = 0.006). Results were similar with rHu α-enolase testing.Conclusion:In SSc, AFA recognise α-enolase and are associated with ILD and antitopoisomerase antibodies.

Systemic sclerosis (SSc) is a systemic autoimmune disease affecting multiple organ systems, including the lungs. Interstitial lung disease (ILD) is the leading cause of death in SSc.There are no valid biomarkers to predict the occurrence of SSc-ILD, although auto-antibodies against anti-topoisomerase I and several inflammatory markers are candidate biomarkers that need further evaluation. Chest auscultation, presence of shortness of breath and pulmonary function testing are important diagnostic tools, but lack sensitivity to detect early ILD. Baseline screening with high-resolution computed tomography (HRCT) is therefore necessary to confirm an SSc-ILD diagnosis. Once diagnosed with SSc-ILD, patients' clinical courses are variable and difficult to predict, although certain patient characteristics and biomarkers are associated with disease progression. It is important to monitor patients with SSc-ILD for signs of disease progression, although there is no consensus about which diagnostic tools to use or how often monitoring should occur. In this article, we review methods used to define and predict disease progression in SSc-ILD.There is no valid definition of SSc-ILD disease progression, but we suggest that either a decline in forced vital capacity (FVC) from baseline of ≥10%, or a decline in FVC of 5–9% in association with a decline in diffusing capacity of the lung for carbon monoxide of ≥15% represents progression. An increase in the radiographic extent of ILD on HRCT imaging would also signify progression. A time period of 1–2 years is generally used for this definition, but a decline over a longer time period may also reflect clinically relevant disease progression.

Objectives. To examine the characteristics of our patients with limited systemic sclerosis (lSSc) for differences between Barnett Type 1 (sclerodactyly only) and Type 2 or intermediate (acrosclerosis-distal but may reach up to elbows and/or knees plus face) subsets.Methods. Records of patients between January 1, 2000, and December 31, 2011, with SSc or those with anti-Scl-70, anticentromere, or antinucleolar antibodies were reviewed. Only cases fulfilling ACR 1980 criteria were included and classified as diffuse or limited according to LeRoy’s criteria. Limited SSc was separated into sclerodactyly and acrosclerosis (Barnett’s Types 1 and 2).Results. 234 SSc patients (216 females) fulfilled criteria. Female/male ratio was 12 : 1; 24% had dSSc and 76% lSSC (64% Type 1 and 12% Type 2). Total follow-up was 688 patient-years. Within lSSC, the Type 2 group had significantly shorter duration of Raynaud’s and more anti-Scl-70 and less anticentromere antibodies. In particular, interstitial lung disease (ILD) was significantly more prevalent in Type 2 group and similar to Type 3.Conclusions. These results appear to confirm that extension of skin involvement within limited SSc may identify two different subsets with clinical and serologic characteristics.

Krebs von den Lungen-6 (KL-6) levels measured at baseline have been reported as a circulating biomarker useful for the detection, evaluation of severity and assessment of risk of the progression of interstitial lung disease (ILD) in patients with systemic sclerosis (SSc). In this retrospective study, longitudinal changes in serum KL-6 levels over 2 years were examined in 110 patients with SSc using prospectively collected cohort data. Serum KL-6 levels fluctuated in a significant proportion of the patients but remained stable in the remaining patients. A wide range of variability of longitudinal KL-6 levels was associated with the presence of ILD, diffuse cutaneous SSc, positive anti-topoisomerase I antibodies, negative anticentromere antibodies, increased ILD extent on high-resolution computed tomography, extensive disease, low pulmonary function parameters, high KL-6 levels at baseline and immunomodulatory treatment. Extensive disease was consistently identified as an independent factor associated with variability in KL-6 levels in different models of multiple regression analysis. We failed to demonstrate correlations between trends for KL-6 level changes during the 6 months after SSc diagnosis and ILD progression over 2 years in patients with SSc-ILD. Serum KL-6 levels fluctuate in SSc patients with ILD, especially in those with extensive disease, but the clinical utility of a serial KL-6 level measurement remains uncertain.

Substantial Morbidity

Interstitial lung disease (ILD) has been recognized as a frequent manifestation associated with a substantial morbidity and mortality burden in patients with autoimmune rheumatic disorders. Serum autoantibodies are considered good biomarkers for identifying several subsets or specific phenotypes of ILD involvement in these patients. This review features the role of several autoantibodies as a diagnostic and prognostic biomarker linked to the presence ILD and specific ILD phenotypes in autoimmune rheumatic disorders. The case of the diverse antisynthetase antibodies in the antisynthease syndrome or the anti-melanoma differentiation-associated 5 protein (MDA5) antibodies as a marker of a severe condition such as rapidly progressive ILD in patients with clinically amyopathic dermatomyositis are some of the associations herein reported in the group of myositis spectrum disorders. Specific autoantibodies such as the well-known anti-topoisomerase I (anti-Scl70) or the anti-Th/To, anti-U11/U12 ribonucleoprotein, and anti-eukaryotic initiation factor 2B (eIF2B) antibodies seems to be specifically linked to ILD in patients with systemic sclerosis. Overlap syndromes between systemic sclerosis and myositis, also have good ILD biomarkers, which are the anti-PM/Scl and anti-Ku autoantibodies. Lastly, other not so often reported disorders as being associated with ILD but recently most recognized as is the case of rheumatoid arthritis associated ILD or entities herein included in the miscellaneous disorders section, which include anti-neutrophil cytoplasmic antibody-associated interstitial lung disease, Sjögren’s syndrome or the mixed connective tissue disease, are also discussed.

Circulating Biomarkers

Interstitial lung disease is a frequent organ manifestation in systemic sclerosis and is associated with high mortality. It is crucial to diagnose interstitial lung disease in systemic sclerosis and to assess severity and identify patients prone to progression at an early stage to ultimately decrease organ damage and improve outcome. Circulating anti-topoisomerase-I autoantibodies have long been associated with the presence and development of systemic sclerosis – interstitial lung disease, evidence on their potential to further predict the clinical course of systemic sclerosis is however conflicting. C-reactive protein is a marker of infection and systemic inflammation with widespread clinical application and is elevated in systemic sclerosis with a tendency towards higher abundancy in patients with early disease. The role of other circulating biomarkers is promising but hampered by the lack of standardized criteria and guidelines for sample/data collection, analyses, reporting and validation and has not reached prime time for clinical application. However, epithelial markers including Krebs von den Lungen-6 and surfactant protein D and several cytokines and chemokines including CCL2 and CCL18 for severity assessment of systemic sclerosis – interstitial lung disease patients at the time of interstitial lung disease diagnosis and to predict interstitial lung disease progression have been reported and seem to be promising candidate biomarkers in the future.

Objective: To evaluate clinical, laboratory, or radiographic predictors of the onset of interstitial lung disease in systemic sclerosis. Methods: Sixty-five out of 220 systemic sclerosis outpatients, without interstitial lung disease at baseline and with ⩾3 chest high resolution computed tomography scans during follow-up were recruited. Thoracic lymphadenopathy and interstitial lung disease were assessed by chest high resolution computed tomography. Hazard ratio (95% confidence interval) of interstitial lung disease occurrence was assessed by Cox regression models, adjusting patient’s demographics and disease characteristics. Sensitivity, specificity, and accuracy of the interstitial lung disease predictors were evaluated by receiver operating characteristic analysis. Results: The development of interstitial lung disease was observed in 44/65 (68%) patients. Thoracic lymphadenopathies was detected in 40/65 (61%) patients, of whom 36 (82%) developed interstitial lung disease, but only four patients with thoracic lymphadenopathies did not develop ILD at last visit of follow-up (19%) (p = 0.0001). Adjusted hazard ratio of systemic sclerosis-interstitial lung disease onset was 5.8 (95% confidence interval, 2.0–16.5) for thoracic lymphadenopathy, which preceded by 108 ± 98 weeks the systemic sclerosis-interstitial lung disease detection. Thoracic lymphadenopathy had 84% specificity, 81% sensitivity, and 0.82 accuracy to predict interstitial lung disease. In particular, anticentromere antibodies or limited cutaneous subset of systemic sclerosis patients with thoracic lymphadenopathy showed earlier interstitial lung disease onset than those without lymphadenopathy. In addition, patients who developed interstitial lung disease had higher frequency of anti-Scl-70 (57% vs 19%; p = 0.009) and diffuse cutaneous subset (29% vs 3%; p = 0.02) than those who did not. Conclusions: Thoracic lymphadenopathy was the strongest independent predictor of systemic sclerosis-interstitial lung disease, mostly in anticentromere antibodies and limited cutaneous subset of systemic sclerosis patients. Further prospective studies are needed to confirm our preliminary data and to understand whether thoracic lymphadenopathies may have a pathogenetic role in interstitial lung disease development.
