Interstitial lung disease (ILD) is frequently seen in Connective Tissue Disorders (CTDs), most commonly in systemic sclerosis, rheumatoid arthritis, idiopathic inflammatory myositis, systemic lupus erythematosus, Sjogren's syndrome, and systemic vasculitides. Recognizing them early is of paramount importance for the timely initiation of treatment. Various modalities of detection of ILD are present of which high-resolution computed tomography is the most sensitive. This article focuses on the prevalence of ILD in various CTDs. It presents the data which have been published in different parts of the world and from India. The common subtypes of ILD found in each CTD and autoantibody association have been discussed. It briefly discusses various epidemiological factors associated with ILD and factors that predispose the patient to the development of ILD. Wherever available, morbidity and mortality data are also presented.
