<p class="abstract"><strong>Background:</strong> The auto-immune connective tissue diseases (AICTD) are polygenic clinical disorders having heterogeneous overlapping clinical features. Certain features like autoimmunity, vascular abnormalities, arthritis/arthralgia and cutaneous manifestations are common to them. Lung involvement can present in AICTDs in form of: pleurisy, acute/ chronic pneumonitis, pulmonary artery hypertension (PAH), shrinking lung syndrome, diffuse alveolar damage, pulmonary embolism (PE), bronchiolitis obliterans organizing pneumonia, pulmonary infections, cardiogenic pulmonary edema, etc. High-resolution computed tomography (HRCT) plays an important role in identifying patients with respiratory involvement. Pulmonary function tests are a sensitive tool detecting interstitial lung disease.</p><p class="abstract"><strong>Methods:</strong> The present study is an observational study carried out on 170 patients of AICTD in department of Dermatology, Venereology and Leprosy at a tertiary care centre during a period of 2 years from October 2017 to August 2019. Detailed history, examination and relevant investigations like chest X-ray, pulmonary function test (PFT), HRCT thorax were done as indicated.<strong></strong></p><p class="abstract"><strong>Results:</strong> The overall incidence of respiratory involvement was 56.7% with maximum involvement in systemic sclerosis cases (82.8% of cases). 45.7% of patients of systemic lupus erythematosus had respiratory involvement, most common being pleural effusion in 11.5%. Impaired PFT’s were seen in 82.8% cases of systemic sclerosis (SSc)  and all cases of UCTD. Interstitial lung disease was seen in 34.7% and 25% cases of SSc and DM respectively. PAH was found in 15.2% cases of SSc and 9.8% cases of mixed connective tissue diseases.</p><p class="abstract"><strong>Conclusions:</strong> AICTD are multisystem disorders in which pulmonary involvement can be an important cause of morbidity to the patient and early detection is necessary for prevention of long-term respiratory complications.</p>

Background:Interstitial lung disease (ILD) is a common manifestation of connective tissue diseases (CTDs), and is associated with significant morbidity and mortality. Chest high-resolution computed tomography (HRCT) play an important role in the diagnosis of ILD and may provide prognostic information.Objectives:We aimed to characterize the clinical profile and chest HRCT abnormalities and patterns of patients diagnosed with CTDs and ILD.Methods:In this retrospective, observational study we included 80 consecutive patients with CTDs and ILD referred to a tertiary rheumatology center between 2015 and 2019. From hospital charts we collected clinical data, immunologic profile, chest HRCT findings. HRCT patterns were defined according to new international recommendations.Results:Out of 80 patients, 64 (80%) were women, with a mean age of 55 years old. The most common CTD associated with ILD was systemic sclerosis (38.8%), followed by polymyositis (22.5%) and rheumatoid arthritis (18.8%). The majority of patients had dyspnea on exertion (71.3%), bibasilar inspiratory crackles were present in 56.3% patients and 10% had clubbing fingers. Antinuclear antibodies (ANA) were present in 78.8% patients, and the most frequently detected autoantibodies against extractable nuclear antigen were anti-Scl 70 (28.8%), followed by anti-SSA (anti-Ro, 17.5%), anti-Ro52 (11.3%) and anti-Jo (7.5%). Intravenous cyclophosphamide therapy for 6-12 months was used in 35% of patients, while 5% of patients were treated with mycophenolate mofetil.The most frequent HRCT abnormalities were reticular abnormalities and ground glass opacity. Non-specific interstitial pneumonia (NSIP) was identified in 46.3% CTDs patients. A pattern suggestive of usual interstitial pneumonia (UIP) was present in 32.5% patients, mainly in patients with systemic sclerosis. In 21.3% patients the HRCT showed reticulo-nodular pattern, micronodules and other abnormalities, not diagnostic for UIP or NSIP pattern.Conclusion:Nonspecific interstitial pneumonia (NSIP) is the most common HRCT pattern associated with CTDs. Further prospective longitudinal studies are needed in order to determine the clinical and prognostic significance of various HRCT patterns encountered in CTD-associated ILD and for better patient management.References:[1]Ohno Y, Koyama H, Yoshikaua T, Seki S.

Abstract Background: The aim of this study was to investigate clinicoserologic biomarkers associated with the development, progression, and prognosis of connective tissue diseases associated interstitial lung disease (CTD-ILD). Methods: We conducted a single center, a retrospective study including 70 incident patients diagnosed with CTD-ILD and 70 age-, sex-, and type of CTD-matched patients without ILD. Clinical informations, pulmonary function test, and chest CT findings were reviewed using medical records. To identify serologic biomarkers, serum interferon-r-induced protein 10 (IP-10), interleukin (IL)-6, IL-8, IL-10, and matrix metalloproteinase 7 (MMP-7) in patients with CTD-ILD and CTD without ILD were measured. Results: A total of 140 patients were enrolled. The mean was 63.3 ± 11.2 years, and 102 (72.9%) patients were female. Raynaud`s phenomenon (OR 5.96, 95% CI 2.11–16.86) was proved to be a risk factor for developing ILD in CTD by multivariable logistic regression analysis. To analyze distinctive features according to the onset of ILD, CTD-ILD was stratified into three groups: ILD-preceding, simultaneous, and CTD-preceding. The majority of the ILD-preceding group (75%) had worse baseline pulmonary function requiring treatment (DLCO <65%). Serum levels of MMP-7 were associated with the development of ILD in patients with CTD, and also had a significant correlation with CT extent score in the present study. Conclusion: In this study, Raynaud`s phenomenon, and serum levels of MMP-7 were clinicoserologic biomarkers CTD-ILD. Therefore, clinicoserologic biomarkers associated with ILD should be assessed in patients with CTD to provide proper management.

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.

Objective.To evaluate the clinical benefits of the endothelin receptor antagonist bosentan on interstitial lung disease (ILD) in patients with systemic sclerosis (SSc) who are ineligible for cyclophosphamide (CYC) therapy.Methods.In this prospective open-label study, 9 patients with SSc and ILD received bosentan for 24 months. The main reasons for avoiding CYC included severely impaired lung function, long disease duration, and relapse after CYC treatment. Pulmonary function tests and Doppler echocardiograms were evaluated every 6 months, and high-resolution computed tomography (HRCT) was performed every 12 months. For an extended survival analysis, 17 historical controls who met the inclusion criteria at referral and had not used any immunosuppressive or antifibrotic agents thereafter were selected from the SSc database.Results.Two patients did not finish the study; one developed vasculitis requiring high-dose corticosteroids and another died of bacterial pneumonia. The remaining 7 patients tolerated bosentan and completed the study period. There were trends toward mildly reduced forced vital capacity, total lung capacity, and diffusing capacity for carbon monoxide over time. Two patients developed pulmonary hypertension during the 24-month period. HRCT scores for ground-glass opacity, pulmonary fibrosis, and honeycomb cysts gradually increased. In the extended study, there was no difference in cumulative survival rate between the bosentan-treated and historical control groups.Conclusion.The gradual worsening of pulmonary function and HRCT findings in patients treated with bosentan was consistent with the natural course of SSc-associated ILD. This study does not support the use of bosentan for SSc-associated ILD even when CYC treatment is inadvisable.

Juvenile Systemic Sclerosis

Background:Juvenile systemic sclerosis (jSSc) is an orphan disease with a prevalence in around 3 in a million children. Pulmonary involvement in jSSc occurs in approximately 40 % in the inception cohort. Traditionally in jSSc, pulmonary function testing (PFT) with FVC and DLCO are used for screening and computed tomography (HRCT) was more reserved for those with abnormal PFTs. More recently, it has become apparent that PFTs might not be sensitive enough for detecting ILD in children.Objectives:Utilizing a prospective international juvenile systemic scleroderma cohort (JSScC) [2], to determine if pulmonary screening with FVC and DLCO is sufficient enough to assess the presence of interstitial lung disease in comparison to CT evaluation.Methods:The international juvenile systemic scleroderma cohort database was queried for available patients with recorded PFT parameters and HRCT performed to determine sensitivity of PFTs detecting disease process.Results:Of 129 patients in the jSScC, 67 patients had both CT imaging and an FVC reading from PFTs for direct comparison. DLCO readings were also captured but not in as many patients with tandem HRCT (n =55 DCLO and HRCT scan). Therefore, initial analyses focused on the sensitivity, specificity and accuracy of the FVC value from the PFTs to capture the diagnosis of interstitial lung disease as determined by HRCT.Overall, 49% of the patients had ILD determined by HRCT, with 60% of patients having normal FVC (>80%) with positive HRCT findings, and 24% of patients having normal DLCO (> 80%) with positive HRCT findings. Fourteen percent (n = 3/21) of patients with both FVC and DLCO values within the normal range had a positive HRCT finding.Conclusion:The sensitivity of the FVC in the JSScC cohort in detecting ILD was only 39%. Relying on PFTs alone for screening for ILD in juvenile systemic sclerosis would have missed the detection of ILD in almost 2/3 of the sample cohort, supporting the use of HRCT for detection of ILD in children with SSc. In addition, the cut off utilized, of less than 80% of predicted FVC or DLCO could be too low for pediatric patients to exclude beginning ILD. This pilot data needs confirmation in a larger patient population.Supported by the “Joachim Herz Stiftung”Disclosure of Interests:Ivan Foeldvari Consultant of: Novartis, Bernd Hinrichs: None declared, Kathryn Torok: None declared, Maria Jose Santos Speakers bureau: Novartis and Pfizer, Ozgur Kasapcopur: None declared, Amra Adrovic: None declared, Valda Stanevicha: None declared, Flávio R.

Objective.To compare survival of patients with connective tissue disease-associated interstitial lung disease (CTD-ILD) versus idiopathic pulmonary fibrosis (IPF) and patients with systemic sclerosis-associated ILD (SSc-ILD) versus other CTD-ILD followed at our center.Methods.We used the Stanford ILD database, which contains prospectively collected information on patients with ILD evaluated at our tertiary care center from 2002 to 2009. Survival at last followup from time of ILD diagnosis was calculated using the Kaplan-Meier estimator. Prognostic factors for survival in the overall cohort (IPF and CTD-ILD) and in the CTD-ILD group were identified with univariate and multivariate Cox regression models.Results.Of 427 patients with ILD, 148 (35%) had IPF and 76 (18%) had CTD-ILD at the baseline visit. The cumulative incidence of CTD was 4%. After a median followup of 4 years, 67 patients (36.4%) had died and 4 (2.2%) were lost to followup. Patients with IPF (n = 122) and CTD-ILD (n = 62) experienced similar survival rates (5-year survival about 50%). Patients with SSc-ILD (n = 24) experienced better survival than those with other CTD-ILD (n = 38), with 1-year, 3-year, and 5-year survival rates of 100%, 90%, and 77%, respectively, versus 78%, 42%, and 38% (p = 0.01). The presence of SSc in patients with CTD-ILD decreased the risk of death by > 80% even after correcting for age at ILD diagnosis, sex, and ethnicity (HR = 0.17, 95% CI 0.04–0.83).Conclusion.Survival in patients with SSc-ILD was better than in patients with other CTD-ILD, potentially related to routine screening for and early detection of ILD in patients with SSc at our center.
