ABSTRACT
Objective To explore the effect of PBMC HBV cccDNA in HBsAg-positive mothers on neonatal Th1, Th2 cytokines and the ratio of Th1/Th2. Methods HBsAg-positive mothers and their neonates delivered in the Third People’s Hospital of Taiyuan between June 2011 and July 2013 were recruited. Questionnaires on general information were collected by an in-person interview. Electrochemiluminescence immunoassay (ECLIA) were utilized to detect HBV serological markers.HBV cccDNA in PBMC was detected with real-time PCR-TaqMan Probe method, Th1 cytokines (interleukin 2, interferon-γ and tumor necrosis factor-α) and Th2 cytokines (interleukin 4, interleukin 6 and interleukin 10) were detected with Procarta Plex Multiplex Immunoassays. Results Univariate analysis showed that the levels of IL-2, IL-6 and IL-10 in the positive group were significantly higher than those in the negative group, while the ratio of Th1/Th2 was lower than that in the negative group (P=0.034, P=0.007, P=0.048, P=0.029). The levels of IL-6 and IL-10 in neonates delivered by vagina were significantly higher than those by cesarean section, while the ratio of Th1/Th2 was lower than that by cesarean section (P<0.001). The level of IL-10 in positive group of neonatal HBsAg was significantly higher than that in negative group, while TNF-α and Th1/Th2 ratio were lower than negative group (P=0.011, P<0.001, P=0.027). The degree of Th2 predominant response was reflected by ratio of Th1/Th2. After adjusting potential confounding factors in non-conditional logistic regression analysis, compared to those born to mothers with PBMC HBV cccDNA negative, neonates whose mother with PBMC HBV cccDNA positive had an increased risk of having a strong Th2 predominant response (OR=2.42,95% CI:1.16-5.04, P=0.018). The risk of a strong Th2 predominant response in neonates delivered by vagina was 5.49 times higher than those by cesarean section (OR=5.06, 95% CI: 2.95-8.67, P<0.001). Conclusion HBsAg-positive mothers’ PBMC HBV replication and vaginal delivery may increase the risk of having a Th2 predominant response in neonates. It is suggested that we should pay attention to the effect of maternal PBMC HBV replication and the mode of delivery on neonatal Th1/Th2 cytokines.
