The relative contributions of acute and chronic inflammatory mechanisms in diseases characterised by persistent bacterial infection are unclear, despite important consequences for the development of novel anti-inflammatory therapies. Here, we examined longitudinal transcriptional and epigenetic changes in patients with Cystic Fibrosis (CF), a genetic condition characterised by persistent bacterial lung infections that drive progressive inflammatory lung damage. We find that sudden clinical deteriorations in lung health, termed Acute Pulmonary Exacerbations (APEs), are linked to innate immune signalling driven by bacterial components, and accompanied by changes in macrophage function. Treatment of patients with intravenous antibiotics results in rapid modification of myeloid cell gene expression and epigenetic state, towards that of healthy volunteers, suggesting that repeated acute inflammatory episodes play an important role in CF inflammatory lung damage.
