Change in gait speed and adverse outcomes in patients with idiopathic pulmonary fibrosis: A prospective cohort study

Contemporary Concise Review 2023: Interstitial lung disease

In this review, we have discussed several important developments in 2023 in Interstitial Lung Disease (ILD). The association of pollution with genetic predispositions increased the risk of Idiopathic Pulmonary Fibrosis (IPF). An interesting comorbidity of malnutrition was not adequately recognized in ILD. Novel genes have been identified in IPF involving predominantly short telomere length and surfactant protein production leading to alveolar epithelial cell dysfunction. Genetics also predicted progression in IPF. Crosstalk between vascular endothelial cells and fibroblasts in IPF mediated by bone morphogenic protein signalling may be important for remodelling of the lung. A novel modality for monitoring of disease included the 4-min gait speed. New treatment modalities include inhaled pirfenidone, efzofitimod, for sarcoidosis, and earlier use of immunosuppression in connective tissue disease-ILD.
