RÉSUMÉ
Objective To investigate the effect of intensive phototherapy for neonatal hyperbilirubinemia on cellular immune function and short-term immune-related adverse effects.Methods Totally 180 infants with hyperbilirubi-nemia were treated with different light intensity,the efficacy,cellular immune function and immune adverse effects were followed up for six months after discharge.Results After phototherapy,serum interleukin-6(IL-6)in both groups were decreased and CD4+(%)and CD4+/CD8+were increased than that before phototherapy.The decrease rate of total bilirubin in the intensive phototherapy group was significantly faster than that in the conventional photo-therapy group,at the same time,the total duration of phototherapy and hospital stay were significantly shorter than that in the conventional phototherapy group(P＜0.05).No statistical significance in the incidence of diarrhea,rash,fever and hypo-calcemia during hospitalization and no immune-related adverse effects in 6 months after discharge were recorded.Conclusions Compared with conventional phototherapy,intensive phototherapy reduces serum bilirubin level more quickly and shorten the duration of phototherapy and hospital stay.No common adverse effects nor immune-related adverse effects are recorded during hospitalization and the period of six months after discharge.
