Clin Transplant 2011: 25: 468–474. © 2010 John Wiley & Sons A/S. Abstract: This is a prospective, observational study of a consecutive cohort of allogeneic hematopoietic stem cell transplantation (allo‐HSCT) adult recipients conducted between July 2003 and May 2006, with the aim of identifying the current incidence, etiology, risk factors for infections and associated mortality up to two yr after allo‐HSCT. Seventy‐four episodes of infection were recorded in 38 patients, 50 consecutive adult patients underwent 54 allo‐HSCT. The incidence of infection was 1.36 (68/50) episodes/patient after the first year of transplantation and 1.48 (74/50) episodes/patient after first two yr of transplantation. The most common syndrome was cytomegalovirus (CMV) infection, followed by catheter‐related bloodstream infection and pneumonia. An etiological diagnosis was established in 85.1% of the episodes. Bacteria were the most common etiology (55.5%), followed by viruses (41.3%) and fungi (4.8%). CMV was the most common viral agent (73%), and all fungal infections were caused by molds. Myeloablative conditioning regimen, chronic graft‐versus‐host disease, and medical complications post‐transplant were independent risk factors for infection. The global mortality two yr after transplantation was 32%, and death was infection related in 12%. In spite of advances, infections continue to be a common cause of morbidity and mortality following allo‐HSCT.
