Respiratory syncytial virus (RSV) is a frequent cause of respiratory tract infectious disease (RTID) in allogeneic hematopoietic stem cell transplant (HSCT) recipients associated with a high mortality once infection has progressed from upper RTID (URTID) to lower RTID (URTID). Aerosolized ribavirin (RBV) is considered a cornerstone of treatment, but is expensive and has toxic side effects on patients and staff. In this study, RSV infection was detected by polymerase chain reaction (PCR) from routinely collected throat swabs in HSCT patients. Infected individuals were treated according to an institutional protocol using intravenous (IV) RBV for patients with LRTID and oral ribavirin for URTID. ⋯ We show that IV and oral RBV were efficacious in preventing progression and reducing mortality of RSV infection in this small series of allogeneic HSCT recipients. Randomized studies are not to be expected for this condition and therefore reporting case series could help in determining optimal RSV treatment.

Strongyloides stercoralis is a helminth in tropical and subtropical areas. It may cause latent infection and progress to Strongyloides hyperinfection syndrome, which is associated with a high mortality rate. Transplant recipients under the treatment of immunosuppressant agents are at risk of severe S. stercoralis infection. ⋯ We report on an intestinal transplant recipient who had S. stercoralis infection diagnosed by a larva of this parasite found in the stool from the ileostomy stoma 1 month after transplantation. The donor was considered the source of the infection because the donor was from an endemic area and had marked eosinophilia, and the recipient had no contact history or clinical manifestations related to the S. stercoralis infection before transplantation. The patient was treated with ivermectin and exhibited no evidence of infection after 7 months.
