An approach to interstitial lung disease in India
Keywords:Usual interstitial pneumonia â€“ sarcoidosis, pneumoconiosis, bronchoscopy, lung biopsy
Interstitial lung diseases are common and have varied etiology, clinical presentation, clinical course and outcome. They pose a diagnostic challenge to physicians and pulmonologists. Patients present with dry cough, exertional dyspnoea, interstitial lesions on X-ray of the chest and restrictive ventilatory defect on spirometry. A sharp decline in oxygen saturation with exercise is characteristic. Careful evaluation of the history of the patient and physical examination help in narrowing down diagnostic probabilities. HRCT of the chest has emerged as an important tool in the evaluation of these disorders. Idiopathic Interstitial Pneumonias (IIP) are a group of conditions which are classified into several types based on pathological features. Bronchoscopic procedures are helpful in diagnosis of certain disorders but are of limited value in classification of IIP which requires surgical biopsy. Usual Interstitial Pneumonia (UIP), also referred to as Idiopathic Pulmonary Fibrosis, has a progressive course and an unfavourable outcome. Certain new drugs have recently become available for treatment of UIP. Our approach towards diagnosis and management of interstitial lung diseases based on personal experience over the past three decades is reported here.
