Abstract:
Objective To investigate the relationship between neonatal umbilical cord blood cytokine interferon-γ (IFN-γ),interleukin-4 (IL-4),interleukin-12 (IL-12),interleukin-18 (IL-18) and hepatitis B virus (HBV) intrauterine infection.Methods Seventy-five newborns delivered by HBsAg-positive pregnant women in the First Hospital of Hebei Medical University and the Fifth Hospital of Shijiazhuang from December 2017 to June 2018 were selected as observation group.According to the results of five items of hepatitis B and HBV DNA test in cord blood of newborns,17 of them were positive as intrauterine infection group,and 58 of them were negative as uninfection intrauterine group.Forty-three newborns delivered by healthy pregnant women with negative HBsAg were taken as control group.The levels of cytokines IFN-γ,IL-4,IL-12 and IL-18 in cord blood of neonates were detected by ELISA,Results The levels of IFN-γ,IL-4,IL-12 and IL-18 in the newborns of intrauterine infection group were (409.51 ±51.77),630.51(612.49,647.33),85.60(56.11,133.99),32.41 (23.04,87.53) ng/L.The levels in the uninfected intrauterine Group were (523.87 ± 38.45),573.33 (531.95,598.38),186.53 (77.77,302.66),125.99(63.32,202.73) ng/L.The levels in the control group were (509.39±73.02),565.83 (443.40,620.82),199.89 (128.92,289.30),152.98 (86.76,188.57) ng/L.There were significant differences in IFN-γ,IL-4,IL-12,IL-18 between the intrauterine infection group and the uninfected intrauterine group and the control group (all P＜0.01).There was no significant difference between the uninfected group and the control group (all P＞0.05).Conclusion The decrease of IFN-γ,IL-12,IL-18 and the increase of IL-4 in cord blood of neonates result in the decrease of viral clearance ability and the failure of HBV clearance,which leads to intrauterine infection of neonates with HBV.
