An association between cytomegalovirus infection and pre-eclampsia: a case–control study and data synthesis
2010
AbstractObjective. Pre-eclampsia shares several similarities with atherosclerotic heart disease. We explored whether, like atherosclerosis, there is a potential link between cytomegalovirus (CMV) infection and pre-eclampsia. Design. CMV IgG, IgM and IgA antibodies were determined by enzyme-linked immunosorbent assays in serums from pre-eclampsia (n = 78), normotensive intrauterine growth restriction (nIUGR) (n = 30) and normal pregnancy controls (n = 109). Data were analyzed by chi-squared, Kruskal–Wallis ANOVA and Mann–Whitney U-tests. Further, we conducted a comprehensive review of published studies on the relation between CMV infection and pre-eclampsia. Risk ratios (RRs) and 95% confidence interval (CI), according to CMV infection status, were calculated using Review Manager. Main outcome measures. Women with pre-eclampsia had increased CMV IgG seropositivity compared with nIUGR (p < 0.01) and normal pregnancy controls (p < 0.01). In addition, CMV IgG antibody level was higher in pre-eclampsia than no...
