Current knowledge of risk factors for graft-versus-host disease (GVHD) in pediatric bone marrow transplantation is derived from studies focusing primarily on adults. We reviewed 100 pediatric HLA-matched allogeneic marrow transplants to identify donor and recipient factors (age, sex, age mismatch, sex mismatch) associated with increased incidence of acute or chronic GVHD. The incidence of acute (32%) and chronic (29%) GVHD were very low. In univariate analyses, recipient age (P = 0.003), donor age (P = 0.002), donor sex (P = 0.089) and age mismatch (P = 0.018) are related to acute GVHD. Prior acute GVHD (P = 0.0001), recipient age (P = 0.057), donor age (P = 0.016), donor sex (P = 0.01) and sex mismatch (P = 0.024) are associated with chronic GVHD. In multivariate analyses, older donor age (P = 0.003) and female donor sex (P = 0.046) independently predict acute GVHD. Only acute GVHD (P = 0.0001) was independently related to chronic GVHD. When acute GVHD was excluded, older donor age (P = 0.032) and sex mismatch (P = 0.005) predict chronic GVHD. Thus, the incidence of acute and chronic GVHD were very low in our pediatric population, especially in the youngest patients. Older donor age and female donor sex are associated with a higher incidence of acute GVHD. Prior acute GVHD, older donor age and sex mismatch are associated with a higher incidence of chronic GVHD. |
