Viral Respiratory Infections Diagnosed by Multiplex PCR after Allogeneic Hematopoietic Stem Cell Transplantation: Long-Term Incidence and Outcome

Viral respiratory infections (VRIs) are frequent after hematopoietic stem cell transplantation and constitute a potential cause of mortality. We analyzed the incidence, risk factors, and prognosis of VRIs in a cohort of transplanted patients. More frequent viruses were human coronavirus and human rhinovirus followed by flu-like viruses and adenovirus. Risk factors for death were lymphocytopenia and high steroid dosage.
