Clinical significance of predictive and diagnostic indices of fetal pathology associated with placental insufficiency in women with endometriosis
BACKGROUND: Modern achievements of pharmacology, surgery and reproductive medicine have determined an increase in the implementation of reproductive function in endometriosis of various localization. The onset of pregnancy in presence of impaired endometrial receptivity and progesterone resistance, pro-inflammatory and pro-thrombotic status, abnormal functioning of the immune system, structural changes in the reproductive organs leads to impaired formation of the embryo (feto) placental system, early reproductive losses, complicated pregnancy and adverse perinatal outcomes. In this regard, the endometriosis and pregnancy issue requires close study and specific proposals to optimize pregnancy management. AIM: The aim of this study was to develop predictive (PIs) and diagnostic (DIs) indices of placenta-associated fetal pathology in pregnant women with endometriosis, to determine their prognostically and diagnostically significant parameters. MATERIALS AND METHODS: This prospective study in the dynamics of gestation included a comprehensive clinical and laboratory examination of 175 pregnant women with endometriosis (100 subjects with adenomyosis and 75 subjects with ovarian endometriosis). To develop PIs and DIs, two comparison groups with fetal pathology due to placental insufficiency were retrospectively identified, depending on the location of endometriosis. Group I consisted of 49 pregnant women with adenomyosis and placental insufficiency isolated from other pregnancy complications, accompanied by growth retardation and/or chronic fetal hypoxia; Group II comprised 29 pregnant women with ovarian endometriosis and placental insufficiency isolated from other pregnancy complications, accompanied by growth retardation and/or chronic fetal hypoxia. The control group (Group III) included 30 healthy pregnant women with a normal course of gestation. The examination was performed at 10-14 weeks, 20-24 weeks, and 28-34 weeks of gestation and included an assessment of placental insufficiency markers such as placental growth factor (PlGF), placental -1-microglobulin (PAMG-1), tumor necrosis factor (TNF), lymphocytes with membrane receptor FasR (L CD95+), C-reactive protein, placental alkaline phosphatase (PAPh), and fetal hemoglobin (HbF). The information value of individual parameters and indices was determined by ROC analysis, odds ratio, and clinical epidemiology tests. RESULTS: Pregnancy in presence of endometriosis in 100% of cases was complicated by placental insufficiency of varying severity (with fetal pathology in 81.5% of cases), the frequency of which had statistically significant differences between the groups of pregnant women with adenomyosis and ovarian endometriosis (2 = 4.06, p = 0.04). To predict growth retardation and / or chronic fetal hypoxia, we have developed PI I (PlGF / TNF 100) and PI II (PAMG-1 / PlGF 100), which characterize the state of placental angio-and vasculogenesis depending on systemic inflammatory response level. For early diagnosis of fetal pathology, we have proposed DI I (CRP / PAPh 100), DI II (HbF / PlGF 100) and DI III (L CD95+ / PAPh 100), which allow for diagnosing placental alterations with impaired placental energy supply due to an increase in inflammatory status. Evaluation of prognostic and diagnostic significance of PIs and DIs showed that the most informative tools are PI I (Se = 86.1%, Sp = 80.5%) and DI I (Se = 88.3%, Sp = 83.7%). CONCLUSIONS: The use of PIs allows for risk stratification of pregnant women from the 1st trimester of gestation to address the issue of the prevention method. The clinical capabilities of DIs optimize obstetric tactics for the timely prescription of therapy for placental insufficiency and targeted diagnosis of fetal pathology. Pregnant women with endometriosis should be classified as a high perinatal risk group, and therefore the proposed PIs and DIs should be included in the dynamic examination complex.

Here we analysed rare and acute complications of endometriosis in pregnant women by searching Cochrane, HINARY, and PubMed databases. Keywords were “rare”, “causes”, “acute”, “complications”, “endometriosis”, and “pregnancy”. The search depth was 10 years (2011−2021). In total, we found 126 publications, 41 of which met the selection criteria. The course of pregnancy and childbirth in patients with endometriosis is insufficiently studied. Yet, it is characterised by a higher risk of complications including those rarely occurring: haemoperitoneum, intestinal perforation, appendicitis, torsion and rupture of the endometrioid cyst, and thoracic endometriosis. Because of major hormonal changes occurring during the pregnancy, endometriosis undergoes a significant progression or decidualisation. As endometrioid tissue is characterised by a resistance to progesterone, its defciency during the pregnancy can lead to necrosis, perforation of decidualised foci, and severe bleeding. Progesterone deficiency provokes hypervascularisation of the endometrioid tissue, which is the most common cause of spontaneous haemoperitoneum and most frequently occurs in the third trimester of pregnancy and after in vitro fertilisation. Pregnancy increases the risk of endometriosis-related intestinal perforation of different localisation: small intestine, caecum, appendix, and rectosigmoid colon. Limited information about the pregnancy-related complications of endometriosis leads to their underestimation, albeit they can be life-threatening and significantly impact the health of the mother and fetus. The results of this review indicate the need for the further studies of the pregnancy course in patients with endometriosis, especially after the use of assisted reproductive technology. Development of specific clinical guidelines would contribute to the efficient prevention of obstetric and perinatal complications in patients with endometriosis.
Aim. To review the current publication highlighting the features of pregnancy and childbirth outcomes in patients with endometriosis. Materials and methods. The analysis of 45 foreign and domestic publications on this topic has been carried out. Results. Patients with endometriosis have fertility problems, and when pregnancy occurs, it was characterized by a higher risk of preeclampsia, placenta previa, gestational diabetes, miscarriage and preterm labor, as well as delivery by caesarean section. Newborns in women with endometriosis have an increased risk of prematurity and small for gestational age. Probably, in addition to the presence of endometriosis, the risk of obstetric and neonatal complications is influenced by the localization and severity of the disease, as well as the use of assisted reproductive technologies. Conclusion. The results obtained indicate that patients with endometriosis have a high risk of perinatal complications and require additional antenatal monitoring and care.
