Abstract

Stem cell transplant recipients are susceptible to pulmonary infections, including influenza A. Typically, isolated influenza pneumonia has a diffuse, interstitial infiltrate pattern. To describe the unusual clinical and radiographic course of influenza A pneumonia in a stem cell transplant recipient. Case report in which microbiologic assays, bronchoscopic and pathologic specimens are obtained. We describe a patient with influenza A pneumonia 8 months following a peripheral blood stem cell transplant who presented with minimal respiratory symptoms and rapidly progressing, focal pulmonary infiltrates. The large size and appearance of the masses have not been reported before in a patient with isolated influenza. This case highlights the differences of presentation and importance of early diagnosis and treatment of immunocompromised patients infected with influenza.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
