Objectives: MicroRNAs have been observed to play a major role in various physiological processes, for instance, programmed cell death, cell division, pregnancy development, and proliferation. With the help of profiling of microRNAs in the serum of pregnant women, it is possible to link alterations in their concentration to the emergence of gestational problems. The aim of the study was to evaluate the diagnostic potential of MicroRNAs Mi 517 and Mi 526 as biomarkers in the detection of hypertension and preeclampsia.

Material and methods: The study considered 53 patients who are in their first trimester of a singleton pregnancy. Participants have been divided into two study groups, one group with normal pregnancy and another group having the risk of developing preeclampsia or who developed hypertension or preeclampsia during follow-up constitute the study group. In order to collect data associated with circulating miRNAs in serum, blood samples have been collected from the participants of the study.

Results: Based on the univariate regression model, increased expression of Mi 517 and 526 and parity status (primapara/multipara) has been obtained. The multivariate logistic analysis shows that independent risk factors for hypertension or preeclampsia are the presence of an R527 and being a primipara.

Conclusions: The study's findings have revealed that R517s and R526s act as major indicative biomarkers in the first trimester for the detection of hypertension and preeclampsia. The circulating C19MC MicroRNA was examined as a potential early indicator of preeclampsia and hypertension in pregnant individuals.
