Introduction

Interstitial lung diseases (ILDs) represent a heterogeneous group of more than 200 conditions characterized by inflammation and fibrosis of the lung interstitium, leading to progressive dyspnea and cough.

Etiology and Classification

ILDs can be idiopathic, related to systemic diseases, or due to environmental exposures. The most common idiopathic ILD is idiopathic pulmonary fibrosis (IPF). Other forms include nonspecific interstitial pneumonia and sarcoidosis.

Clinical Manifestations and Diagnosis

Patients typically present with progressive dyspnea and dry cough. Physical examination may reveal crackles and clubbing. High-resolution CT is the gold standard for diagnosis. Pulmonary function tests show a restrictive pattern and reduced diffusion capacity.

Treatment and Prognosis

Treatment is largely supportive, including oxygen therapy and pulmonary rehabilitation. Antifibrotic drugs like pirfenidone and nintedanib are approved for IPF. Prognosis varies widely, with IPF having a median survival of 2-3 years post-diagnosis.

Conclusion

ILDs are complex disorders requiring a thorough understanding for effective management. Further research is needed to develop more effective treatments and improve patient outcomes.
