- African American race was associated with postengraftment blood stream infections
- Cytomegalovirus viremia was also associated with subsequent blood stream infections
- Neutropenia may have partly accounted for the excess blood stream infection after cytomegalovirus viremia
Blood stream infections (BSI) are a major source of morbidity and mortality both in allogeneic blood and marrow transplant (BMT) recipients. Various risk factors for BSI in BMT have been identified. The impact of race and cytomegalovirus (CMV) viremia, a common complication after engraftment, however, has not been rigorously assessed. This is important because both CMV infection and ganciclovir, the mainstay of pre-emptive therapy, have myelosuppressive and immunosuppressive effects. We conducted a retrospective analysis to test the hypothesis that race and CMV viremia predispose allogeneic BMT patients to postengraftment BSI. We analyzed 278 allogeneic BMT performed at Children's Healthcare of Atlanta between January 1, 2005 and December 31, 2014 that met eligibility criteria. We performed a multivariate analysis to estimate the effect of CMV viremia on risk for BSI in the postengraftment period (days +30 to 100). Risk for BSI was associated with CMV viremia (hazard ratio [HR],â3.34; 95% confidence interval [CI], 1.51 to 7.36; Pâ=â.003); grade III and IV acute graft-versus-host disease (HR,â3.28; 95% CI, 1.55 to 6.92; Pâ=â.002), and African American race (HR,â2.22; 95% CI, 1.09 to 4.51; Pâ=â.027). The results of our study highlight the importance of a novel risk factor for postengraftment BSI, not previously considered-African American race.
