In conclusion, our data suggest that MBL2 genotypes may influence the course of febrile neutropenia in pediatric patients with malignancies, and may contribute to clarification of the importance of MBL in infections.
Deficiency of mannose-binding lectin (MBL) has been suggested to influence duration of febrile neutropenia and prognosis in paediatric oncology patients.
In one additional MBL level study the number of FN episodes, bacteremia and severe bacterial infection were increased in patients with MBL levels < 100 µg/L as compared to those with MBL levels of 100-999 µg/L.
Individuals with the lowest serum MBL concentrations at the time of diagnosis (<1000 microg/L) had a higher median number of days of febrile neutropenia than did individuals with higher concentrations of MBL (p=0.012).
