Early viral complications following CD34‐selected autologous peripheral blood stem cell transplantation for non‐Hodgkin's lymphoma

Abstract

A patient with non‐Hodgkin's lymphoma who received a CD34‐selected autologous peripheral blood stem cell transplant (PBSCT) developed cytomegalovirus retinitis, adenovirus‐associated haemorrhagic cystitis (HC) and fatal herpes simplex virus pneumonia. Depletion of mature T cells from the graft and a persistent decrease in CD4 + lymphocytes following PBSCT may have predisposed this patient to such viral infections. Infusion of cryopreserved autologous PBSC (containing mature T cells) was effective for adenovirus‐associated HC. Immunosuppression and resultant viral infections may affect patients receiving CD34‐selected autologous transplantation.
