Question 1

How is a diagnosis of pulmonary fibrosis made? How does one differentiate between chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis in a basic medical setup?

COPD is a disease affecting the airways and is defined as a common, preventable, and treatable disease that is characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities usually caused by a significant exposure to noxious particles or gases.[1]

Idiopathic pulmonary fibrosis (IPF) is defined as spontaneously occurring (idiopathic) specific form of chronic fibrosing interstitial pneumonia limited to the lung and associated with a pattern of usual interstitial pneumonia on high-resolution computed tomography (HRCT) or histologic appearance on surgical (thoracoscopic or open) lung biopsy.[2]

Patients with these two diseases may have similar risk factors, history, and complaints. However, it is very important to differentiate them as the treatment is very different and the prognosis is much poorer for patients with IPF. Clinical examination, chest X-ray, spirometry, and HRCT help differentiate between these two diseases [Table 1].

In a low-resource setting, chest X-ray and spirometry are useful investigative modalities along with the clinical findings to help a physician come to a reasonable diagnosis.
