ReviewPathogenesis of idiopathic pulmonary fibrosis and its clinical implications.
Idiopathic pulmonary fibrosis (IPF) is the most common and lethal form of idiopathic interstitial pneumonia. The disease is thought to arise following an aberrant reparative response to recurrent alveolar epithelial cell injury leading to progressive loss of function. The median survival time is 3-5 years from diagnosis. ⋯ In the last decade, several clinical trials evaluating novel therapies for IPF have been conducted but the results have been mostly disappointing. Conversely, compounds that target anti-fibrotic and growth factor pathways have been proven effective in slowing functional decline and disease progression. These promising results notwithstanding, truly effective therapeutic strategies will likely require combinations of drugs in order to target the multitude of pathways involved in disease pathogenesis.
