A 40-year-old pregnant woman admitted into hospital to treat hypertension (HT) and gestational diabetes at 19 weeks of gestation. She contracted enterocolitis due to the foodborne pathogen Yersinia enterocolitica (YE) at 22 weeks of gestation. Hypoalbuminemia and ascites developed due to prolonged intractable diarrhea and vomiting. Since 25 weeks of gestation, marked albuminuria appeared and blood pressure gradually elevated. Fetal growth was found to be retarded.
