Controlling infections in hospitalized pretransplant candidates.

Purpose of review: Infections in hospitalized patients awaiting solid organ transplantation can pose complicated diagnostic and therapeutic challenges. Goals of management include stabilizing the patient, treating or controlling infections, and decreasing the risk of reactivation of infection after transplant.

Recent findings: Groups such as The Organ Procurement and Transplantation Network, American Society of Transplantation Infectious Diseases Community of Practice and the European Society of Clinical Microbiology and Infectious Diseases have updated their guidelines on screening and treatment of infection in transplant candidates. There are also recent developments in therapeutic options for tuberculosis, COVID-19, Clostridioides difficile colitis, bloodstream infections, and other common infections.

Summary: Ideally, antimicrobial therapy should be complete prior to transplantation. In situations in which completion of therapy prior to transplant is not feasible, therapy may need to be prolonged or modified. In most situations, infections can be managed similarly to the general population, although some infections, particularly fungal and mycobacterial, require a different management approach. We review disease- and organ-specific management.
