The Improvement Effect of Different Doses of Gamma Globulin on the Disease Condition of Infants with Hemolytic Disease of Newborn and Their Effects on Immune Factors in Serum

Background: to explore the effect of different doses of gamma globulin (gg) on the condition of children with hemolytic disease of newborn (hdn) and the influence of immune factors in serum. methods: overall, 180 infants with hemolytic disease of newborn in the people’s hospital of zhangqiu area, jinan, china from april 2016 to august 2018 were divided into group a (88 cases) and group b (92 cases). group a was given intravenous low-dose gg on the basis of phototherapy, and group b was given intravenous high-dose gg on the basis of phototherapy. the level of serum total bilirubin of the infants, the levels of cd3+, cd4+, cd8+, iga, igg and igm of the infants, the time of jaundice disappearance and the length of hospital stay, hemoglobin and reticulocyte levels were recorded before treatment and after treatment. the number and condition of adverse reactions were recorded. results: after treatment, the levels of tbil, hemoglobin and reticulocyte, the time of jaundice disappearance and hospital stay in group b were significantly lower than those in group a. the level of immune cells in group b was significantly higher than that in group a after 7 days of treatment, and the levels of iga / igg / igm in group b were significantly higher than those in group a after 28 days of treatment. conclusion: intravenous high-dose gg has a better effect on the condition of neonatal hemolytic disease patients, and more effectively improve the immune function of children.
