Abstract
Pneumocystis cariniipneumonia (PCP), which is currently referred to asPneumocystis jiroveciipneumonia, is an opportunistic fungal infection that commonly affects immunocompromised patients, and it is potentially fatal. Individuals at risk include those whose host immunity has been altered by underlying disease states, such as HIV and cancer patients, as well as transplant recipients and those taking immunosuppressive medications. Here, we present a case of a breakthrough PCP infection of an adult allogeneic hematopoietic stem cell transplant patient who was infected despite prophylaxis with inhaled pentamidine. The patient's transplant course was complicated by acute graft-versus-host disease (GVHD), which was treated with tacrolimus, prednisone, beclomethasone, and budesonide. Treatments for GVHD, which include immunosuppressive therapies, are a risk factor for PCP. Thus, the patient was on prophylactic treatment with inhaled pentamidine. The case presents challenges that immunocompromised patients face, particularly those undergoing allogeneic hematopoietic stem cell transplantation. While the patient received prophylactic treatment, there was still a breakthrough PCP infection. We highlight the risks this infection can cause and the need to promptly address these infections to prevent complications and optimize prophylactic regimens.
