Idiopathic pulmonary fibrosis: Current and future treatment

Daniel S Glass et al. Clin Respir J. 2022 Feb.

Abstract

Objectives: Idiopathic pulmonary fibrosis (IPF) is a chronic fibrotic lung disease characterized by dry cough, fatigue, and progressive exertional dyspnea. Lung parenchyma and architecture is destroyed, compliance is lost, and gas exchange is compromised in this debilitating condition that leads inexorably to respiratory failure and death within 3-5 years of diagnosis. This review discusses treatment approaches to IPF in current use and those that appear promising for future development.

Data source: The data were obtained from the Randomized Controlled Trials and scientific studies published in English literature. We used search terms related to IPF, antifibrotic treatment, lung transplant, and management.

Results: Etiopathogenesis of IPF is not fully understood, and treatment options are limited. Pathological features of IPF include extracellular matrix remodeling, fibroblast activation and proliferation, immune dysregulation, cell senescence, and presence of aberrant basaloid cells. The mainstay therapies are the oral antifibrotic drugs pirfenidone and nintedanib, which can improve quality of life, attenuate symptoms, and slow disease progression. Unilateral or bilateral lung transplantation is the only treatment for IPF shown to increase life expectancy.

Conclusion: Clearly, there is an unmet need for accelerated research into IPF mechanisms so that progress can be made in therapeutics toward the goals of increasing life expectancy, alleviating symptoms, and improving well-being.

Keywords: idiopathic pulmonary fibrosis; lung transplantation; nintedanib; pentraxin; pirfenidone.

Comparison of healthy lung to idiopathic pulmonary fibrosis (IPF) lung. The healthy lung is characterized by unscarred airways with thin‐walled alveoli and unimpeded gas exchange. Pathological features of the IPF lung include dilated bronchi, airway distortion, and thickened alveolar walls. Inflammation and fibrosis lead to impaired gas exchange within the alveoli
