ABSTRACT
Background: Interstitial lung disease accounts for more than 200 etiology. There has been worldwide increase in diagnosis of interstitial lung disease because of the help of recent advance diagnostic tools. Aims & Objective: to study age & sex distribution, to correlate symptoms & pulmonary function, role of HRCT as etiology diagnosis particular in interstitial pulmonary fibrosis, to study ECG & 2D ECHO changes and to study pulmonary function test pattern. Material and Methods: This was the study of 25 cases of interstitial lung disease in which various parameters like DLCO, PFT, 2D ECHO, ECG, identification of etiology, assessment of prognosis & role of immunosuppressant, steroids were studied. The exclusion criteria was age < 12 years. Results: The age distribution was highest in age group of 50-70 years. Occupational interstitial lung disease was more common in male while the connective tissue disorders are common in female which lead to more incidence of interstitial lung disease. Pulmonary function test is very helpful for prognosis. The patient with high pulmonary artery pressure had worst prognosis. HRCT is a useful tool for diagnosis of IPF without biopsy. Conclusion: Interstitial lung disease with moderate to severe pulmonary artery hypertension leads to poor prognosis. HRCT is very useful non-invasive diagnostic tool for interstitial lung disease.
