Background: The term interstitial lung diseases (ILD) refer to a broad category of lung diseases rather than a specific disease entity. True prevalence of ILD is difficult to estimate and it may vary according to the geography, environment, occupation etc. Aim and objectives were to find out the distribution of interstitial lung disease (ILD) subtypes in a tertiary care centre.  Methods: A descriptive study was conducted between August 2016 and November 2018 in a tertiary care centre in Puducherry, South India. Baseline demographic details, clinical symptoms, signs, radiological findings (chest radiograph and HRCT), pathological findings, and physiological findings were taken into consideration and diagnosis of type of interstitial lung disease was made using multidisciplinary discussion. Statistical analysis was done using SPSS 19.0 version.Results: A total of 150 patients were recruited of which 70.5% were females. Most common ILD subtype in our study was connective tissue disease associated ILD – 97 patients (65%) followed by idiopathic pulmonary fibrosis (IPF)–31 patients (22%). Most common type of CTD ILD observed in our study was progressive systemic sclerosis (46%) followed by mixed connective tissue disease (24%). The most common HRCT finding was NSIP pattern and most commonly observed physiological abnormality was moderate restriction and moderate diffusion impairment.  Conclusions: Connective tissue disease-associated ILD was the most common ILD found in our study amongst south Indian population. This suggests that the distribution of ILD would vary depending on the geographical area and the environmental exposure which was in contrast with the Indian ILD registry.

Undifferentiated Connective Tissue Disease

Our study compared the prevalence and characteristics of patients with connective tissue disease-associated interstitial lung disease (CTD-ILD), undifferentiated connective tissue disease-associated interstitial lung disease (UCTD-ILD), or idiopathic pulmonary fibrosis (IPF) between January 2009 and December 2012 in West China Hospital, western China. Patients who met the criteria for ILD were included and were assigned to CTD-ILD, UCTD-ILD, or IPF group when they met the criteria for CTD, UCTD, or IPF, respectively. Clinical characteristics, laboratory tests, and high-resolution CT images were analyzed and compared among three groups. 203 patients were included, and all were Han nationality. CTD-ILD was identified in 31%, UCTD-ILD in 32%, and IPF in 37%. Gender and age differed among groups. Pulmonary symptoms were more common in IPF, while extrapulmonary symptoms were more common in CTD-ILD and UCTD-ILD group. Patients with CTD-ILD had more abnormal antibody tests than those of UCTD-ILD and IPF. Little significance was seen in HRCT images among three groups. A systematic evaluation of symptoms and serologic tests in patients with ILD can identify CTD-ILD, UCTD-ILD, and IPF.

Data Registry

Objectives: The burden of interstitial lung disease (ILD) is rising globally. This study aimed to describe and compare characteristics of Connective Tissue Disease-associated ILD with Idiopathic Pulmonary Fibrosis, the two most commonly observed ILDs among outpatients at a tertiary care hospital in Karachi, Pakistan. Methods: A retrospective research study was conducted. Patients with ILD were identified through the outpatient data registry at the Aga Khan University Hospital (AKUH), Karachi from October 2016 to October 2017. We obtained data pertaining to demographics, clinical and radiologic features. A comparative analysis was done to compare the patient characteristics and key features between CTD-ILD and IPF patients. The analysis was done using STATA version 12.0. Results: We identified 184 patients with ILD, which included 52 (29.3%) with CTD-ILD and 62 (35%) with IPF. The most prevalent conditions among CTD-ILD patients included rheumatoid arthritis (42.3%) and scleroderma (25%). Usual interstitial pneumonitis was the common radiologic pattern in RA-ILD (63.6%) and scleroderma (61.5%) while non-specific interstitial pneumonitis was more common in MCTD (85.7%) and SLE (80%). Compared to patients with IPF, those with CTD-ILD were predominantly younger (p<0.001) and female (88.5 % v 45.2%, p<0.001). History of GERD was also significantly lower in CTD-ILD (p=0.05). Conclusion: CTD-ILD patients in our registry were younger and predominantly female compared to IPF. Further studies and ongoing data registry are needed to understand the full spectrum of this disease and long term clinical outcomes.

Was ist neu? Glukokortikosteroide und Immunsuppressiva In der Therapie der Lungengerüstveränderungen bei Patienten mit Kollagenose (connective tissue disease-associated interstitial lung disease, CTD-ILD) werden Kortikosteroide, Immunsuppressiva und auch Biologika angewendet. Im Vergleich zur Scleroderma-Lung-Study (SLS) I und II, die die Effektivität der Immunsuppressiva Cyclophosphamid (CYC) und Mycophenolat-Mofetil (MMF) bei pulmonaler Beteiligung der Sklerodermie (SSc-ILD) belegen, ist die Datenlage bezüglich der Therapie der anderen CTD-ILD unbefriedigend. Biologika In der Gruppe der Biologika nimmt Rituximab (RTX) an Bedeutung zu. Die aktuell erwarteten Studienergebnisse werden die Wirksamkeit von Immunsuppressiva (vor allem MMF und CYC) mit RTX bei verschiedenen CTD-ILD vergleichen. Zu den weiteren untersuchten Biologika gehören u. a. der monoklonale Anti-IL6-Rezeptor-Antikörper Tocilizumab bei SSc-ILD bzw. Abatacept (ein Fusionsprotein, das die T-Zell-Antworten inhibiert) bei pulmonaler Beteiligung bei rheumatoider Arthritis (RA-ILD). Autologe Stammzelltransplantation Die autologe Stammzelltransplantation ist eine potente, aber nebenwirkungsbehaftete Therapie bei schwerer Sklerodermie. Antifibrotische Therapie Für die Gruppe der Lungengerüstkrankheiten unterschiedlicher Genese inkl. CTD-ILD mit einem progredienten fibrosierenden Verlauf trotz adäquater Therapie (z. B. chronische exogen-allergische Alveolitis, RA, SSc) wurde der Begriff der fibrosierenden interstitiellen Lungenerkrankungen mit progressivem Phänotyp (progressive fibrosing interstitial lung diseases, PF-ILD) geprägt. In jüngster Zeit erschienen Arbeiten, die einen positiven Effekt der antifibrotischen Medikamente (Nintedanib, Pirfenidon) in einer solchen Situation nachweisen. Aktuell wird eine Reihe weiterer Ergebnisse bezüglich der Effektivität der Antifibrotika bei CTD-ILD erwartet. Die Studien auf diesem Gebiet haben das Potential der Erweiterung der Behandlungsmöglichkeiten bei CTD-ILD.

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.
