Correlation study between human parvovirus B19 and spontaneous abortion / 中国医师进修杂志

ABSTRACT

Objective To investigate the correlation between human parvovirus (HPV) B19 and spontaneous abortion.Methods Participants included 30 cases of spontaneous abortion patients (patients group) and 30 normal pregnancy (control group).The potential risk of spontaneous abortion factors were recorded.Extracting all subjects cubits venous blood,HPV B19 DNA was tested by nested polymerase chain reaction,and HPV B19 IgM antibodies were determined by ELISA.The more factors analysis were performed by Logistic multiple regression analysis.Results There were significant differences in gravidity more than 2 times,combined with hypertension,combined with diabetes,HPV B19 DNA positive expression between patients group and control group [43.3％(13/30) vs.13.3％(4/30),33.3％(10/30) vs.6.7％(2/30),30.0％ (9/30) vs.6.7％ (2/30),36.7％ ( 11/30 ) vs.3.3％ ( 1/30)] (P ＜ 0.05 ).Logistic multiple regression analysis showed that gravidity more than 2 times,combined with hypertension,HPV B19 DNA positive expression were the independent risk factors of spontaneous abortion (OR =1.85,1.95,4.85,P ＜ 0.05).There was significant difference in the risk between early spontaneous abortion and lately spontaneous abortion in HPV B19 DNA positive expression patients (P ＜ 0.05 ).Conclusions HPV B19 infection is the natural abortion independent risk factors,need to early detection of pregnancy,and carry out necessary intervention in pregnant women,in order to reduce the occurrence of natural abortion.
