During 2009, a new strain of A/H1N1 influenza appeared and became pandemic. A prospective study was performed to collect data regarding risk factors and outcome of A/H1N1 in hematopoietic stem cell transplant recipients. Only verified pandemic A/H1N1 influenza strains were included: 286 patients were reported, 222 allogeneic and 64 autologous recipients.(More)
BACKGROUND AND OBJECTIVES Cytomegalovirus (CMV) disease remains an important complication of allogeneic stem cell transplantation (SCT). We studied viral load kinetics and correlated the viral load and other transplant factors with the development of CMV disease. DESIGN AND METHODS We studied 162 consecutive patients who were CMV seropositive or had CMV(More)
The outcome of adenovirus (ADV) infections in adult hematopoietic stem cell transplant (HSCT) patients remains poorly characterized. We studied 14 adults and 3 children, who had undergone HSCT and had developed ADV viremia. Peak ADV DNA levels were significantly higher in patients with ADV diseases than in those without (P=0.03). All children survived the(More)
Cytomegalovirus (CMV) infection represents a vital complication after Hematopoietic Stem Cell Transplantation (HSCT). We screened the entire CMV proteome to visualize the humoral target epitope-focus profile in serum after HSCT. IgG profiling from four patient groups (donor and/or recipient +/- for CMV) was performed at 6, 12 and 24 months after HSCT using(More)
Cytomegalovirus (CMV) reactivation may lead to CMV disease associated with high morbidity and mortality in patients after hematopoietic stem cell transplantation (HSCT); the identification of clinically relevant markers may aid in the identification of patients at increased risk for developing CMV-associated complications. We evaluated the phosphorylation(More)
