How does influenza A (H1N1) infection proceed in allogeneic stem cell transplantation recipients?

Abstract

The clinical course of influenza A (H1N1) infection in allogeneic hematopoietic stem cell transplantation (AHSCT) recipients is not clearly known. We report 3 AHSCT recipients that were infected with influenza A (H1N1). Each of the patients had a different hematological disease and was at a different post-transplantation stages. All the patients were treated with oseltamivir, and zanamivir was switched to oseltamivir in 1 patient. All the patients survived without any complications. The course of swine flu can vary and progress with bacterial or other viral infections in immunosuppressed patients.
