Dealing With Antibiotic Prophylaxis in Lung Transplantation in the Era of Multidrug Resistance: The Milano Algorithm.

Infectious complications significantly impact morbidity and mortality following lung transplantation (LuTx), with over 25% of post-transplant deaths attributed to infections. Antibiotic prophylaxis during the surgical procedure is crucial for reducing early infections, though the current use of wide-spectrum antibiotics, especially in cases of multidrug-resistant organisms (MDROs), is contentious and varies widely across centre. This practice raises concerns about antimicrobial resistance (AMR), particularly in immunosuppressed patients requiring lifelong healthcare access. Syndromic multiplex polymerase chain reaction (mPCR) tests, which detect multiple pathogens simultaneously, have shown promise in quickly identifying pathogens and resistance mechanisms, thus enabling targeted treatments. However, their application in LuTx has been limited.
