Purpose — to create an algorithm for early diagnosis and differential diagnosis of conditions accompanied by thrombocytopenia (TP) during pregnancy, as well as an algorithm for the treatment of immune thrombocytopenia during pregnancy based on analysis of clinical, laboratory data and obstetric and perinatal results of such pregnant women.
Materials and methods. We analyzed 155 histories of pregnancy and childbirth of women with TP, who underwent inpatient treatment and/or gave childbirth in the obstetric clinic of the State Institution «Institute of Pediatrics, Obstetrics and Gynecology named after Academician O.M. Lukyanova NAMS of Ukraine» from January 2008 to August 2018. According to the inclusion criteria, 111 histories were selected for further analysis. Pregnant women are divided according to the etiological principle of TP into three groups: with gestational thrombocytopenia, immune thrombocytopenia, secondary thrombocytopenia. The first group included 32 women (28.8%), the second — 65 (55.6%), the third — 14 (12.6%). During the selected period of time there were 99 births, 100 babies were born, 1 twin birth.
Results and conclusions. The number of platelets progressively decreases during pregnancy with a minimum in childbirth. The algorithm of examination, the decision on the initiation or intensification of treatment, the choice of monitoring tactics for TP during pregnancy, the calculation of obstetric and perinatal risks, preparation for childbirth and the choice of method depend on the cause of TP and differ significantly. Developed «Algorithm for diagnosis and differential diagnosis in the detection of thrombocytopenia during pregnancy» and «Algorithm for the treatment of immune thrombocytopenia during pregnancy» are aimed at the prevention of obstetric and perinatal complications in pregnant women with thrombocytopenia.
The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local Ethics Committee of an participating institution. The informed consent of the patient was obtained for conducting the studies.
No conflict of interest was declared by the authors.
