Development of Drug Treatment for Pulmonary Nocardiosis

Pulmonary nocardiosis is an acute or chronic, suppurative or granulomatous disease caused by nocardia invading the lungs of the human body. It is a rare opportunistic infection and is common in immunodeficiency populations. With the increase of the number of immunosuppressive hosts in the past decade, the number of cases of nocardia infection has increased year by year, and the mortality rate is high. Early diagnosis and effective treatment and regular monitoring are the key to improve the prognosis. In recent years, progress has been made in the research on the treatment of pulmonary nocardiosis. This article reviews the etiology, epidemiology, clinical manifestations and treatment progress of pulmonary nocardiosis to provide a reference for clinical rational drug use.
