The impact of cytomegalovirus (CMV) serostatus (seropositive [(+)] or seronegative [(-)]) of the donor (D) and recipient (R) on mortality after allogeneic non-T cell-depleted stem cell transplantation (SCT) in the era of preemptive therapy was assessed among 1750 patients by means of multivariable Cox regression models. In an analysis that included only(More)
Herpes simplex virus (HSV) commonly reactivates after stem-cell transplantation (SCT), despite acyclovir prophylaxis. Whether HSV-seropositive recipients with HSV-seronegative or type-discordant donors had more frequent and severe HSV infections than those with HSV type-concordant donors was explored. Banked serum samples from HSV-positive SCT recipients(More)
Parainfluenza virus (PIV) infections may be significant causes of morbidity and mortality in patients undergoing stem cell transplantation, but data regarding their impact on transplant-related mortality is limited. This study sought to determine the risk factors of PIV acquisition and progression to lower respiratory tract infection , their impact on(More)
Leukoreduced blood products are reportedly comparable to cytomegalovirus (CMV)-seronegative products for the prevention of transfusion-transmitted CMV (TT-CMV) infection after stem cell (SC) transplantation. To determine if the incidence of TT-CMV was affected by the increasing use of leukoreduced blood products, we followed a prospective cohort of 807(More)
BACKGROUND APV102002 was an open-label study comparing a dual-boosted HIV-1 protease inhibitor (PI) [fosamprenavir/lopinavir/ritonavir (FPV/LPV/RTV; 1400 mg/533 mg/133 mg twice daily)] and a high dose of FPV/RTV 1400 mg/100 mg twice daily (HD-FPV/RTV) versus the standard FPV/RTV 700 mg/100 mg twice-daily (STD-FPV/RTV) regimen for 24 weeks. METHODS Adult(More)
increasing quality and cost-effectiveness of computer application software has revolutionized the way organizations share and manage their information. Rather than develop custom information systems with their internal programming staffs, many businesses now purchase software available in standard " off-the-shelf " packages. A well-chosen standard package(More)
