RESUMEN
<p><b>OBJECTIVE</b>To investigate therapeutic effect of high-dose intravenous immunoglobulin (IVIG) for early management of ABO hemolytic disease of the newborn (ABO-HDN).</p><p><b>METHODS</b>A total of 121 cases with ABO-HDN were randomly divided into treatment group (n=61) and control group (n=60). In addition to the routine treatment of the control group, IVIG were given at a daily dose of 400 mg/kg to the cases in the treatment group for 2-3 times, and therapeutic effects were evaluated and compared between the two groups.</p><p><b>RESULTS</b>The serum total billirubin concentration on the third day after treatment (153.42-/+45.21 micromol/L) and mean daily serum total billirubin concentration reduction (56.49-/+24.05 micromol/L) in treatment group were lower than those in the control group (P<0.01). The jaundice resolution time (23.51-/+11.19 h) and the phototherapy time (3.01-/+0.89 h) for billirubinemia treatment in treatment group were shorter than those in the control group (P<0.01). The patients in the the treatment group had higher hemoglobin level after treatment (15.59-/+2.01 g/L) than those of the control group (P<0.01).</p><p><b>CONCLUSION</b>High-dose IVIG can effectively arrest the progression of hemolytic disease, quickly reduce serum total billirubin concentration and shorten phototherapy time for early treatment of ABO-HDN.</p>
