Objective:
To measure serum zinc, selenium, retinol and tocoferol levels at diagnosis of pediatric acute lymphoblastic leukemia (ALL) and to compare it to that of a control population. Correlation was made with episodes of febrile neutropenia during the first 8 wk of therapy.
Methods:
Fasting levels of serum zinc, selenium, retinol and tocoferol were measured in 45 children diagnosed with acute lymphoblastic leukemia and in 20 healthy controls.
Results:
Lower levels of baseline selenium and tocoferol were noted in patients who developed febrile neutropenia compared to the patients who did not (p = 0.022 and 0.026 respectively). Serum retinol was also lower in patients who developed sepsis when compared to those who did not.
Conclusions:
Supplementation of antioxidants may be considered in clinical trials aiming at reducing infection related morbidity and mortality.
