Interstitial lung disease

Interstitial lung disease (ILD) is a group of disorders characterized by inflammation and scarring (fibrosis) of the lung tissue, particularly affecting the interstitium, which is the tissue and space around the alveoli (air sacs) in the lungs. This scarring can lead to a decrease in lung function and difficulty breathing.

Symptoms:

• Shortness of Breath
• Chronic Dry Cough
• Fatigue
• Weight Loss
• Clubbing of Fingers

Idiopathic Interstitial Pneumonias (IIPs) include Idiopathic Pulmonary Fibrosis (IPF), which is the most common type and involves progressive lung scarring with no known cause. Other IIPs include Nonspecific Interstitial Pneumonia (NSIP), characterized by varied lung injury patterns, and Desquamative Interstitial Pneumonia (DIP), often linked to smoking and marked by macrophage accumulation in the alveoli. Secondary Interstitial Lung Diseases (ILDs) can arise from connective tissue diseases like rheumatoid arthritis and lupus, drug-induced ILD from medications such as chemotherapeutics, occupational and environmental exposures to substances like asbestos and silica, infections (both viral and fungal), and radiation-induced ILD from cancer treatments.

Managing ILD requires a comprehensive approach, often involving a multidisciplinary team including pulmonologists, rheumatologists, and radiologists, to provide optimal care and improve the quality of life for affected individuals.
