Abstract:
Objective The purpose of this study was to explore the infection characteristic of Toxoplasma gondii (TOX),Rubella virus (RV),Cytomegalovirus (CMV) and Herpes simplex virus Ⅱ type (HSV-Ⅱ) (TORCH) infection in neonate in Tianjin area.Methods TOX-IgM/IgG,RV-IgM/IgG,CMV-IgM/IgG and HSV-Ⅱ-IgM/IgG were detected in serum of 2 273 neonate during 2015～2016 with enzymelinked immunosorbent assay (ELISA).Results The positive rates of TOX IgM,RV-IgM,CMV-IgM and HSV-Ⅱ-IgM were 0.00％(0/2 273),0.00％(0/2 273),0.88％(20/2 273) and 0.00％(0/2 273),respectively and those of TOX-IgG,RV-IgG,CMV-IgG and HSV-Ⅱ-IgG were 3.65％ (83/2 273),86.45％ (1 965/2 273),95.82％(2 178/2 273) and 8.27％(188/2 273),respectively.There was 0.66％ percent (15/2 273) of examinees who were infected by none of TORCH pathogens.There existed significant statistical difference for positive rate between TOX-IgG,RV-IgG,CMV-IgG and HSV-Ⅱ-IgG (x2 =6.747,P =0.000) with consequence of the highest positive rate being CMV-IgG.The positive rates of TOX-IgG and CMV-IgM in neonate of 2016 were significantly less than those in 2015 (x2 =5.789～7.505,P=0.006～0.016) but that of HSV-Ⅱ-IgG of 2016 was statistically higher than that in 2015 (x2 =6.073,P =0.014).The positive rate of CMV-IgM in male neonate in 2015 was significantly higher than that in 2016 (x2 =5.054,P =0.025).As a whole the positive rates of TOX-IgG,RV-IgG,CMV-IgG and HSV-Ⅱ IgG had no differences between different years,so did those between gender groups (x2 =2.23～6.963,P=0.073～0.526).The positive rates of TOX-IgG,RV IgG,CMV-IgG and HSV-Ⅱ-IgG in female neonate in 2015 were statistically different from those in 2016 (x2 =8.247,P =0.041).The female neonate in 2015 had higher infection proportion of TOX-IgG compared with that in 2016 (x2 =6.992,P=0.008).TORCH infection detected in 2 273 cases of neonate had one pathogen infection and multi-pathogen infection with overall six patterns of TORCH infection and all infection patterns had no relationship with year and gender,respectively (P＞0.05).Conclusion RV and CMV were primary pathogens in TORCH infection for neonate in Tianjin area and there were recent infections by CMV.TORCH infection varied in different years and gender groups,which provided experimental data and basis for epidemiology and prevention of TORCH in neonate.
