Idiopathic pulmonary fibrosis (IPF) synonymous with cryptogenic fibrosing alveolitis[5] is a rare, progressive illness of the respiratory system, characterized by the thickening and stiffening of lung tissue, associated with the formation of scar tissue. It is a type of chronic pulmonary fibrosis characterized by a progressive and irreversible decline in lung function.[6][3][4]
The tissue in the lungs becomes thick and stiff, which affects the tissue that surrounds the air sacs in the lungs.[7] Symptoms typically include gradual onset of shortness of breath and a dry cough.[1] Other changes may include feeling tired, and clubbing abnormally large and dome shaped finger and toenails.[1] Complications may include pulmonary hypertension, heart failure, pneumonia or pulmonary embolism.[1]
The cause is unknown, hence the term idiopathic.[2] Risk factors include cigarette smoking, acid reflux disease (GERD), certain viral infections, and genetic predisposition.[1] The underlying mechanism involves scarring of the lungs.[1] Diagnosis requires ruling out other potential causes.[3] It may be supported by a high resolution CT scan or lung biopsy which show usual interstitial pneumonia.[3] It is a type of interstitial lung disease.[3]
People often benefit from pulmonary rehabilitation and supplemental oxygen.[1] Certain medications like pirfenidone (Esbriet) or nintedanib (Ofev) may slow the progression of the disease.[2] Lung transplantation may also be an option.[1]
About 5 million people are affected globally.[8] The disease newly occurs in about 12 per 100,000 people per year.[4] Those in their 60s and 70s are most commonly affected.[4] Males are affected more often than females.[4] Average life expectancy following diagnosis is about four years.[1] Updated international guidelines were published in 2022, which some simplification in diagnosis and the removal of antacids as a possible adjunct therapy.[9]
