Pretreatment of nafithromycin attenuates inflammatory response in murine lipopolysaccharide induced acute lung injury.

Pretreatment of nafithromycin attenuates inflammatory response in murine lipopolysaccharide induced acute lung injury. Cytokine. 2020 Feb 29;129:155049 Authors: Trivedi J, Shaikh J, Chavan N, Thorve D, Chaudhary B, Karade A, Gupta S, Patel A, Bhagwat S Abstract Acute respiratory distress syndrome following an acute lung injury (ALI) is a life threatening inflammatory condition predominantly characterized by vascular protein leakage, neutrophil recruitment and overexpression of proinflammatory cytokines. Pulmonary and systemic bacterial infections are the major cause of ALI wherein the bacterial cell components play a crucial role. Macrolide/ketolide antibiotics are reported to possess immunomodulatory activity; as a result improved survival has been noted in pneumonia patients. Hence immunomodulatory activity of nafithromycin, a novel lactone ketolide antibacterial agent was assessed in the murine LPS induced ALI model. Vehicle, nafithromycin (100 mg/kg), azithromycin (600 mg/kg) and dexamethasone (20 mg/kg) were administered orally, 1 h prior to LPS challenge and bronchoalveolar lavage (BAL) fluid was collected thereafter at 18, 24 and 48 h to determine the total cell count, total protein, myeloperoxidase (MPO), tumor necrosis factor (TNF)-α and interleukin (IL)-6. Results from the current study showed that pretreatment with nafithromycin significantly reduced the total cell count, total protein, MPO, TNF-α and IL-6 levels in...
