Clinicoradiological profile of interstitial lung diseases at a tertiary care center in Northern India: An eight-year study.

BACKGROUND AND

OBJECTIVES

Interstitial lung diseases (ILDs) are a varied group of disorders that have been clubbed together due to some common attributes. The data is abundant from the developed world. However, the developing countries have gradually amassed the knowledge of these disorders and epidemiological data is still missing. We aimed to profile the ILD patients at our center.

METHODS

All ILD patients above the age of 14 years were included in the study. A detailed history, examination, exercise capacity assessment, pulmonary function test and relevant serological investigations were done. Tissue was obtained wherever possible. Diagnosis was made after discussion from concerned specialists.

RESULTS

Among the total 884 subjects recruited, 54% were females with a mean age of 53 years. Most were residents of rural areas. Reticulations and traction bronchiectasis was seen in most subjects. Hypersensitivity pneumonitis was present in 35.9% and connective-tissue disease related ILD (CTD-ILD) in 30.9%.

CONCLUSION

Most common ILDs at our center are hypersensitivity pneumonitis and CTD-ILD. Reticulations and traction bronchiectasis are the most common findings on HRCT thorax.
