Recent advances in nanomedicine therapy for bacterial pneumonia

Abstract

Bacterial pneumonia is one of the most common infectious diseases, a great threat to the health of children and the elderly. In the clinic, due to the extensive use of antibiotics, multi-drug-resistant bacteria have increased in large numbers, seriously affects the treatment of patients with bacterial pneumonia. With the development of nanomedicine, it shows great potential in the treatment of bacterial pneumonia. In this review, it initially comprehensively describes the pathological process of bacterial pneumonia and the current status of its clinical treatment. Then it summarizes the strategies of nanomedicine for the treatment of bacterial pneumonia, including inorganic nanomaterials, polymer nanoparticles, natural source nanomaterials and artificial antimicrobial peptides, with a focus on novel nanomaterials for the treatment of bacterial pneumonia (biomimetic nanomaterials, nanovaccines and genetically engineered nanomaterials). Finally, the prospect of nanomedicine for bacterial pneumonia therapy is discussed in the hope of providing new ideas for the clinical treatment of bacterial pneumonia.
