The objective: to determine the risk factors for the development of early gestational complications and their prognostic value in pregnant women with chronic gastritis.Material and methods. 120 pregnant women at 8–12 weeks of gestation with early gestational complications (threatened abortion (TA), emesis gravidarum, spontaneous miscarriage, missed abortion) were studied. They were divided into two groups: Group 1 included 58 pregnant women with chronic gastritis and Group 2 included 62 women without gastritis. 6 parameters were analysed for factorial attributes: gastritis, gastrin-17 (G-17), progesterone, estradiol, chorionic gonadotropin (HCG), and H.pylory. The method of stepwise inclusion/exclusion was used for the selection of significant factors (Stepwise at the critical threshold for inclusion at p<0,1 and the threshold for exclusion at р>0,2).Results. When the attributes associated with the risk of threatened abortion were selected, 3 factors have been identified: gastritis, gastrin (G-17), progesterone. The risk prediction model based on these attributes is adequate c2=25,7; p<0,001). There was an increase (p=0,01) of the risk of TA with increased progesterone levels, OR = 1,4 (95% CІ 1,1–1,7) for every 10 units of the parameter increase. There was a higher (p<0,001) risk of TA in pregnant women with gastritis, OR = 5,4 (95% CІ 2,2–13,2) compared with pregnant women without gastritis. When the attributes associated with the risk of emesis gravidarum, 2 factors were identified: the presence of gastritis and H. pylori. The risk prediction model built on these attributes is adequate (c2=13,8; p=0,001). There was an increase (p=0,03) in the risk of emesis gravidarum in the presence of H.pylori, OR = 2,9 (95% CІ 1,1–7,6) compared with pregnant women without H. pylori. When the attributes associated with the risk of spontaneous miscarriage were selected, 2 factors were identified: gastritis and HCG. The risk prediction model built on these attributes is adequate (c2=7,7; p=0,02). According to the results of the analysis, there was a decrease (p=0,04) in the risk of spontaneous miscarriage with increasing chorionic gonadotropin, OR = 0,94 (95% CІ 0,89–0,99) for every 1000 units of the parameter increase. A higher (p=0,05) risk of spontaneous miscarriage for pregnant women with gastritis was found, OR = 2,7 (95% CI 1,0–7,1) compared with non-gastric pregnant women. When the attributes associated with the risk of missed abortion were selected, 1 factor was identified (progesterone level). The risk prediction model constructed on this basis is adequate (c2=4,1; p=0,04). A tendency to decrease (p=0,06) in the risk of missed abortion with increasing progesterone, OR = 0,75 (95% CІ 0,55 1,02) for every 10 units of the parameter increase was found.Conclusions. The risk factors for the development of early gestational complications in pregnant women with chronic gastritis are hormonal and infectious factors which may contribute to changes in the gastrointestinal motor and evacuation function, cause changes in the acidity of gastric acid and lead to the development of constipation and endogenous intoxication, which cause nausea and vomiting. The nature of the changes and the degree of their severity determine the various clinical manifestations of gestational complications: emesis gravidarum, spontaneous miscarriage, missed abortion.
