BACKGROUND: The early detection and management of (progressive) interstitial lung disease in patients with connective tissue diseases requires the attention and skills of a multidisciplinary team. However, there are currently no well-established standards to guide the daily practice of physicians treating this heterogenous group of diseases. RESEARCH QUESTION: This paper aimed to identify gaps in scientific knowledge along the journey of patients with connective tissue disease-related interstitial lung disease and to provide tools for earlier identification of interstitial lung disease and progressive disease. STUDY DESIGN AND METHODS: The opinions of an international expert panel, which consisted of pulmonologists and rheumatologists were collected and interpreted in the light of peer-reviewed data. RESULTS: Interstitial lung disease is a common complication of connective tissue diseases, but prevalence estimates vary by subtype. Screening and monitoring by means of clinical examination, chest radiography, pulmonary function testing, and disease-specific biomarkers provide insight into the disease activity of patients presenting with connective tissue diseases in a routine setting. Multiple phenotypic and genotypic characteristics have been identified as predictors of the development and progression of interstitial lung disease. However, these risk factors differ between subtypes. To ensure earlier diagnosis of rapidly progressive phenotypes, a risk-based method is necessary for determining the need for HRCT and additional testing. INTERPRETATION: To reduce the underdiagnosis of CTD-ILDs in clinical practice, a standardized and systematic multidisciplinary risk-based approach is suggested. Collaboration across disciplines is essential for the management of CTD-ILD.
RESUMEN
OBJECTIVES: To untangle the association between smoking and systemic sclerosis (SSc). METHODS: In the European Scleroderma Trials and Research cohort, the autoantibody status was compared between ever-smokers and never-smokers. Time until disease progression was assessed using Kaplan-Meier curves. Cox models were built to investigate the influence of smoking over 15 years of follow-up. All analyses were performed for the total cohort and stratified for sex and for positivity of anti-centromere (ACA) and anti-topoisomerase antibodies (ATA). RESULTS: Overall, 12 314 patients were included in the study. Of these, 10 393 were women (84%), 4637 were ACA-positive (38%), 3919 were ATA-positive (32%) and 4271 (35%) were ever-smokers. In men, but not in women, smoking was associated with mortality (HR 1.63, 95% CI 1.23 to 2.16, p=0.001). Ever-smoking women were at higher risk for skin progression (HR 1.10, 95% CI 1.00 to 1.22, p=0.046) and for 'any organ progression' (HR 1.07, 95% CI 1.00 to 1.13, p=0.036). In women, 34% of never-smokers were ATA-positive compared with 21% of ever-smokers (p<0.001). In the group of ever-smokers, higher exposure rates, reflected by the number of pack-years (OR 0.98, 95% CI 0.97 to 0.99, p<0.001) and by smoking duration (OR 0.96, 95% CI 0.95 to 0.97, p<0.001), were associated with lower frequency of ATA. In ACA-positive patients, the risk of mortality (HR 1.29, 95% CI 1.02 to 1.63, p=0.033), cardiac involvement (HR 1.25, 95% CI 1.03 to 1.43, p=0.001), skin progression (HR 1.21, 95% CI 1.03 to 1.42, p=0.018) and 'any organ progression' (HR 1.14, 95% CI 1.05 to 1.24, p=0.002) was increased among smokers. In ATA-positive smoking patients, mortality (HR 1.40, 95% CI 1.10 to 1.78, p=0.006), skin progression (HR 1.19, 95% CI 1.03 to 1.37, p=0.020) digital ulcers (HR 1.17, 95% CI 1.02 to 1.34, p=0.029) and 'any organ progression' (HR 1.11, 95% CI 1.00 to 1.22, p=0.048) occurred more frequently. CONCLUSIONS: Our stratified analysis demonstrates that smoking is associated with an increased risk for mortality in male SSc patients but not in women. Strikingly, smoking is associated with lower prevalence of ATA positivity, in particular in women. In both ATA-positive and ACA-positive patients, smoking is a risk factor for mortality, skin progression and 'any organ progression'.

BACKGROUND AND OBJECTIVES: In SSc, ILD is a major cause of morbidity and mortality. We aimed to investigate the performance of DLCO (diffusing capacity of lung carbon monoxide) and FVC (forced vital capacity) delta change (Δ) and baseline values in predicting the development of SSc-ILD. METHODS: Longitudinal data of DLCO, FVC, and ILD on the HRCT of SSc patients from the EUSTAR database were evaluated at baseline (t0) and after 12 (±4) (t1) and 24 (±4) (t2) months. RESULTS: 474/17805 patients were eligible for the study (403 females); 46 (9.7%) developed ILD at t2. Positivity for anti-topoisomerase antibodies (117 patients) showed an association with ILD development at t2 (p = 0.0031). Neither the mean t0 to t1 change (Δ) of DLCO nor the mean t0 to t1 FVCΔ predicted the appearance of ILD at t2. Investigating the possible role of baseline DLCO and FVC values in predicting ILD appearance after 24 (±4) months, we observed a moderate predictive capability of t0 DLCO < 80%, stronger than that of FVC < 80%. CONCLUSIONS: We suggest that an impaired baseline DLCO may be predictive of the appearance of ILD after 2 years of follow-up. This result advances the hypothesis that a reduction in gas exchange may be considered an early sign of lung involvement. However, further rigorous studies are warranted to understand the predictive role of DLCO evaluation in the course of SSc.
RESUMEN
Aims: Epicardial adipose tissue (EAT) has emerged as a mediator between systemic inflammatory disorders and cardiovascular disease, and may therefore play a role in the pathophysiology of cardiac involvement in systemic sclerosis (SSc). The aim of this study was to assess the correlation between EAT and left ventricular (LV) function, and to determine the prognostic value of EAT in patients with SSc. Methods and results: Consecutive patients with SSc who underwent non-contrast thorax computed tomography and echocardiography were included. EAT mass was quantified using dedicated software. The study endpoint was all-cause mortality. A total of 230 SSc patients (age 53 ± 15 years, 14% male) were included. The median value of EAT mass was 67â g (interquartile range: 45-101â g). Patients with increased EAT mass (≥67â g) showed more impaired LV diastolic function as compared with patients with less EAT mass (<67â g), and even after adjusting for age and comorbidities, EAT mass was independently associated with LV diastolic function parameters. During a median follow-up of 8 years, 42 deaths occurred. Kaplan-Meier analysis showed that patients with increased EAT mass had higher all-cause mortality rate as compared with patients with less EAT mass (29% vs. 7%; P < 0.001). In the multivariable analysis, EAT was independently associated with all-cause mortality after adjusting for important covariates (HR: 1.006; 95% CI: 1.001-1.010). Conclusion: In patients with SSc, EAT is independently associated with LV diastolic dysfunction and higher mortality rate.
RESUMEN
BACKGROUND: Nintedanib is a tyrosine kinase inhibitor used in the treatment of progressive fibrosing interstitial lung diseases (ILDs). We assessed the safety and tolerability of nintedanib in patients with autoimmune disease-related ILDs and with other ILDs in subgroups by sex. METHODS: In this post-hoc analysis, we pooled data from the two INPULSIS trials in patients with idiopathic pulmonary fibrosis (IPF), the SENSCIS trial in patients with fibrosing ILDs associated with systemic sclerosis, and the INBUILD trial in patients with progressive fibrosing ILDs other than IPF. In each trial, patients were randomly assigned to receive oral nintedanib 150 mg twice daily or matched placebo. We assessed adverse events reported over 52 weeks in patients with autoimmune disease-related ILDs and other ILDs in subgroups by sex. FINDINGS: In these analyses, we included 746 patients with autoimmune disease-related ILDs (523 [70%] were female, 223 [30%] were male; 615 [82%] had systemic sclerosis), of whom 370 (50%) received nintedanib (268 [72%] female and 102 [28%] male patients) and 376 (50%) received placebo (255 [68%] female and 121 [32%] male patients); and 1554 patients with other ILDs (437 [28%] female, 1117 [72%] male; 1061 [68%] with IPF), of whom 888 (57%) received nintedanib (237 [27%] female and 651 [73%] male patients) and 666 (43%) received placebo (200 [30%] female and 466 [70%] male patients). Of 102 male and 268 female patients with autoimmune disease-related ILDs treated with nintedanib, nausea was reported in 21 (21%) male and 92 (34%) female patients, vomiting in 12 (12%) male and 73 (27%) female patients, alanine aminotransferase increase in four (4%) male and 31 (12%) female patients, aspartate aminotransferase increase in three (3%) male and 23 (9%) female patients, and adverse events leading to dose reduction in 18 (18%) male and 101 (38%) female patients; 28 (27%) male and 107 (40%) female patients had at least one treatment interruption. Of 651 male and 237 female nintedanib-treated patients with other ILDs, nausea was reported in 135 (21%) male and 95 (40%) female patients, vomiting in 51 (8%) male and 70 (30%) female patients, alanine aminotransferase increase in 19 (3%) male and 31 (13%) female patients, aspartate aminotransferase increase in 17 (3%) male and 26 (11%) female patients, and adverse events leading to dose reduction in 106 (16%) male and 84 (35%) female patients; 155 (24%) male and 82 (35%) female patients had at least one treatment interruption. The proportions of patients with adverse events leading to discontinuation of nintedanib were similar between female and male patients with autoimmune disease-related ILDs (44 [16%] of 268 vs 17 [17%] of 102), but were greater among female than male patients with other ILDs (62 [26%] of 237 vs 112 [17%] of 651). Across subgroups by diagnosis and sex, diarrhoea was the most frequent adverse event associated with nintedanib (autoimmune-related ILDs: 198 [74%] of 268 female and 73 [72%] of 102 male patients; other ILDs: 155 [65%] of 237 female and 408 [63%] of 651 male patients), and was the event that most frequently led to treatment discontinuation (autoimmune-related ILDs: 20 [7%] female and five [5%] male patients; other ILDs: 16 [7%] female and 27 [4%] male patients). INTERPRETATION: The adverse event profile of nintedanib was generally similar between male and female patients with autoimmune disease-related ILDs, and between male and female patients with other ILDs, but nausea, vomiting, liver enzyme elevations, dose reductions, and treatment interruptions were more frequent in female patients than in male patients. Sex should be considered in the monitoring and management of adverse events that might be associated with nintedanib. FUNDING: Boehringer Ingelheim.

OBJECTIVE: Diffuse cutaneous systemic sclerosis (SSc) is a highly heterogeneous disease. A provisionally approved Composite Response Index in diffuse cutaneous SSc (CRISS) was developed as a 1-year outcome measure for clinical trials. Our goal was to further validate the CRISS by examining agreement between CRISS definitions for improved/non-improved with physicians' evaluation of disease. METHODS: Patient profiles from a large observational cohort were created for 50 random diffuse cutaneous SSc patients of <5 years disease duration with improved CRISS scores after 1 year and 50 with non-improved CRISS scores. Profiles described disease features used during the initial CRISS development at baseline and at 1 year. Each profile was independently rated by 3 expert physicians. Majority opinion determined whether a patient was improved or not improved, and kappa agreement with the CRISS cutoff of 0.6 was calculated. RESULTS: Patients had mean ± SD disease duration of 2.2 ± 1.3 years. There was substantial agreement between the physician majority opinion about each case and the CRISS (κ = 0.76 [95% confidence interval (95% CI) 0.64-0.88]). The agreement between each individual physician opinion and the CRISS was also substantial (κ = 0.70 [95% CI 0.62-0.78]). All CRISS non-improvers were also rated as non-improved by physician majority; however, 12 CRISS improvers were rated as non-improved by physicians. CONCLUSION: There was substantial agreement between the dichotomous CRISS rating and physician assessment of diffuse cutaneous SSc patients after 1 year. This supports the use of a CRISS cutoff at 0.6 for improvement versus non-improvement, although the CRISS tended to rate more patients as improved than did physicians.

BACKGROUND: We aimed to evaluate sex-specific risk of anti-topoisomerase I antibodies (ATA) on mortality, diffuse cutaneous systemic sclerosis, interstitial lung disease, and pulmonary hypertension in two cohorts of people with systemic sclerosis. METHODS: This study was a 10-year analysis of the prospective Leiden Combined Care in Systemic Sclerosis (CCISS) cohort in the Netherlands and the international European Scleroderma Trials and Research (EUSTAR) cohort. We included participants with systemic sclerosis according to the 2013 American College of Rheumatology-European League Against Rheumatism (ACR-EULAR) classification criteria; available autoantibody status; available skin subtyping; at least one available radiographic assessment of interstitial lung disease; and with a known date of disease onset. People with systemic sclerosis were categorised in six risk groups by sex and autoantibody status (anti-centromere antibody [ACA]-positive female, ACA-positive male, ACA and ATA-negative female, ACA and ATA-negative male, ATA-positive female, and ATA-positive male). We constructed Kaplan-Meier curves and Cox proportional hazard models, accounting for left-truncated survival to prevent bias because the date of disease onset (first non-Raynaud's symptom) preceded the date of cohort entry for all patients. The primary outcome was all-cause mortality and the secondary outcomes were diffuse cutaneous systemic sclerosis, interstitial lung disease, and pulmonary hypertension. FINDINGS: 445 (63%) of 708 participants between April 1, 2009, and Jan 1, 2022, in CCISS (101 [23%] male and 344 [77%] female) and 4263 (50%) of 8590 between June 1, 2004, and March 28, 2018, in EUSTAR (783 [18%] male and 3480 [82%] female) were eligible for this study. In both cohorts, ATA expression occurred significantly more often in males than in females (39 [39%] of 101 males vs 67 [19%] of 344 females in CCISS; p<0·0001 and 381 [49%] of 783 males vs 1323 [38%] of 3480 females in EUSTAR; p<0·0001). According to estimated survival rates, 30% of ATA-positive males versus 12% of ATA-positive females died in the CCISS cohort and 33% versus 15% died in the EUSTAR cohort within 10 years. After adjustment for age, race, and autoantibody status, male sex remained the most important risk factor for all-cause mortality (HR 2·9 [95% CI 1·5-5·5] in CCISS, p=0·0018; and HR 2·6 [2·0-3·4] in EUSTAR, p<0·0001). INTERPRETATION: We show that the association between male sex and increased mortality in systemic sclerosis cannot be explained by higher ATA prevalence. However, additional research on the effect of sex-specific characteristics on people with systemic sclerosis is required. FUNDING: None.

BACKGROUND: The current subclassification of systemic sclerosis into cutaneous subtypes does not fully capture the heterogeneity of the disease. We aimed to compare the performances of stratification into LeRoy's cutaneous subtypes versus stratification by autoantibody status in systemic sclerosis. METHODS: For this cohort study, we assessed people with systemic sclerosis in the multicentre international European Scleroderma Trials and Research (EUSTAR) database. Individuals positive for systemic-sclerosis autoantibodies of two specificities were excluded, and remaining individuals were classified by cutaneous subtype, according to their systemic sclerosis-specific autoantibodies, or both. We assessed the performance of each model to predict overall survival, progression-free survival, disease progression, and different organ involvement. The three models were compared by use of the area under the curve (AUC) of the receiver operating characteristic and the net reclassification improvement (NRI). Missing data were imputed. FINDINGS: We assessed the database on July 26, 2019. Of 16â939 patients assessed for eligibility, 10 711 patients were included: 1647 (15·4%) of 10â709 were male, 9062 (84·6%) were female, mean age was 54·4 (SD 13·8) years, and mean disease duration was 7·9 (SD 8·2) years. Information regarding cutaneous subtype was available for 10â176 participants and antibody data were available for 9643 participants. In the prognostic analysis, there was no difference in AUC for overall survival (0·82, 95% CI 0·81-0·84 for cutaneous only vs 0·84, 0·82-0·85 for antibody only vs 0·84, 0·83-0·86 for combined) or for progression-free survival (0·70, 0·69-0·71 vs 0·71, 0·70-0·72 vs 0·71, 0·70-0·72). However, at 4 years the NRI showed substantial improvement for the antibody-only model compared with the cutaneous-only model in prediction of overall survival (0·57, 0·46-0·71 for antibody only vs 0·29, 0·19-0·39 for cutaneous only) and disease progression (0·36, 0·29-0·46 vs 0·21, 0·14-0·28). The antibody-only model did better than the cutaneous-only model in predicting renal crisis (AUC 0·72, 0·70-0·74 for antibody only vs 0·66, 0·64-0·69 for cutaneous only) and lung fibrosis leading to restrictive lung function (AUC 0·76, 0·75-0·77 vs 0·71, 0·70-0·72). The combined model improved the prediction of digital ulcers and elevated systolic pulmonary artery pressure, but did poorly for cardiac involvement. INTERPRETATION: The autoantibody-only model outperforms cutaneous-only subsetting for risk stratifying people with systemic sclerosis in the EUSTAR cohort. Physicians should be aware of these findings at the time of decision making for patient management. FUNDING: World Scleroderma Foundation.
