Abstract

Purpose: To determine the risk of adverse maternal and neonatal outcomes in pregnant women with a hemoglobinopathy trait.

Materials and methods: Retrospective cohort study was conducted to compare adverse maternal and neonatal outcomes between pregnant women with a hemoglobinopathy trait (study group; n = 172), and without a hemoglobinopathy trait (control group; n = 360). The medical data were extracted from clinical records of pregnant women attending antenatal care and delivering at the University Hospital Basel or University Hospital Zurich between 2015 and 2018.

Results: A total of 172 pregnant women with a hemoglobinopathy trait and 360 controls were recruited. Apart from fetal acidosis, the groups did not differ significantly in any variables of adverse neonatal outcomes. Whereas, among the maternal outcomes the rate of abortion, gestational diabetes mellitus, bacteriuria or urinary tract infection, intrahepatic cholestasis, abnormal placentation and anemia postpartum were significantly increased in women with a hemoglobinopathy trait.

Conclusion: In our study, a hemoglobinopathy trait increased the risk of adverse maternal outcomes but did not increase adverse neonatal outcomes.

Keywords: Hemoglobinopathy trait; Maternal outcomes; Neonatal outcomes; Pregnancy.
