[SARS-CoV-2/COVID-19 and Hypertensive Pregnancy Disorders: Evaluation of the CRONOS National Registry]. / Hypertensive Schwangerschaftserkrankungen und SARS-CoV-2/COVID-19: Auswertung des nationalen CRONOS-Registers.

ABSTRACT

SARS-CoV-2 infection and COVID-19 disease are associated with an increased risk of hypertensive pregnancy disease in international registry studies. Preexisting hypertensive disorders are recognized as a risk factor of severe COVID-19 progression in pregnancy. The respective damage to the endothelium is discussed as a pathophysiological commonality of both diseases.Data of the national CRONOS registry (data status 05/2021; 1104 pregnant women with SARS-CoV-2 infection) were analyzed regarding the association of hypertensive pregnancy disease and maternal, pregnancy, neonatal, and COVID-19 disease outcomes. In the presence of hypertensive pregnancy disease, a severe combined outcome of pregnancy (17.3 vs. 4.3%, p=0.001), mother (25.0 vs. 9.4%, p=0.001), and newborn (28.8 vs. 9.1%, p<0.0005) occurred significantly more frequent. In contrast, the outcome of COVID-19 disease did not differ (3.8 vs. 7.5%, p=0.424). The co-occurrence of SARS-CoV-2 infection and hypertensive pregnancy disease should be acknowledged as risk factor during management decisions.
