note = "Funding Information: Financial support from the Sustainable Science Institute. Eighty-four healthy pregnant women, primigravid, younger than 25 years, residing in Quito (2800-m altitude), and attending the prenatal clinic at the {\textquotedblleft}Hospital Gineco Obstetrico Isidro Ayora{\textquotedblright} in Quito, Ecuador, were included. All women at 16 weeks{\textquoteright} pregnancy were invited to take a part in the study; a venous blood sample was taken, processed within 2 hours, and stored at −80C up to the assays. We used a microimmunofluorescence technique (Labsystem, Helsinki, Finland) for the detection of immunoglobulin G antibodies to C pneumoniae, immunoanalysis (Diagnostic Products Corp., Los Angeles, CA) for antibodies to Helicobacter pylori, and nephelometry (Human GmbH, Wiesbaden, Germany) for anti{\textendash}streptolysin O. It was found that 73\% of women ( n = 61) were positive for C pneumoniae, 87\% ( n = 73) for H pylori (cutoff of at least 1 U/mL), and 82\% ( n = 69) for anti{\textendash}streptolysin O (cutoff of at least 61.5 U/mL). After delivery, women were classified as those with a normal pregnancy ( n = 73) and those with preeclampsia ( n = 11 [13.1\%]). Preeclampsia was defined as blood pressure of at least 140/90 mm Hg plus proteinuria of at least 300 mg per 24 hours. Data of these subgroups are shown in Table 1 . ",
