Objective:
To study the clinical profile of patients with idiopathic pulmonary fibrosis (IPF) and methods used for diagnosis.
Methods:
Prospective analysis of symptoms, signs, radiology and lung biopsy of patients freshly diagnosed to have IPF over a 16-month period.
Results:
During the study period, 76 patients (35 men) with a mean age of 50.6 +/- 11.9 years were diagnosed to have IPE Breathlessness (98.6%) and dry cough (92.1%) were the most common presenting symptoms. Transbronchial lung biopsy (TBLB) was performed in 38 (50%) patients. Histopathological examination revealed features consistent with IPF in 35 (92.1%) patients; two of the remaining three patients underwent open lung biopsy. Other patients were diagnosed based on clinical features and high resolution chest tomography (HRCT) findings. HRCT was performed in 69 (90.8%) patients; all had features suggestive of diffuse interstitial fibrosis.
Conclusion:
IPF is diagnosed more commonly now than in the past. Indian patients may be developing the disease a decade earlier than their counterparts in the West. TBLB and HRCT are useful in establishing diagnosis. IPF should be considered a distinct clinical entity rather than a diagnosis of exclusion.

Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
