Risk factors for salivary dysfunction in children 1 year after bone marrow transplantation.
Bone marrow transplantation (BMT) in childhood has improved the survival for children with leukaemia, severe aplastic anaemia and some metabolic disorders. However, transplant procedures are associated with a high incidence of deleterious long-term complications. This study included 49 children, conditioned according to the Seattle protocols. Follow-up oral examinations were performed 1 year after BMT. Forty risk factors that may have influenced a low stimulated salivary secretion rate (SSSR) were studied. An SSSR < or = 0.5 ml/min, 1 year after BMT was regarded as the event. One year after BMT, the mean SSSR was 0.5 +/- 0.4 ml/min in children conditioned with total body irradiation (TBI) compared to 1.0 +/- 0.5 ml/min in non-irradiated children (P = 0.0013). Significant predictors for low SSSR in multivariate analysis were: conditioning with TBI (P = 0.0023), recipient female sex (P = 0.0121) and recipient seropositivity for between three and four herpes viruses (P = 0.0157).
