Pregnancy with endometriosis: Assessment of national-level trends, characteristics, and maternal morbidity at delivery. Eur J Obstet Gynecol Reprod Biol 2024; 299:1-11. [PMID: 38815411 DOI: 10.1016/j.ejogrb.2024.05.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 05/01/2024] [Accepted: 05/11/2024] [Indexed: 06/01/2024]
Abstract
OBJECTIVE To examine pregnancy characteristics and maternal morbidity at delivery among pregnant patients with a diagnosis of endometriosis. STUDY DESIGN This cross-sectional study queried the Healthcare Cost and Utilization Project's National Inpatient Sample. Study population was 17,796,365 hospital deliveries from 2016 to 2020, excluded adenomyosis and uterine myoma. The exposure was endometriosis diagnosis. Main outcome measures were clinical and pregnancy characteristics and severe maternal morbidity at delivery related to endometriosis, assessed with multivariable regression model. RESULTS Endometriosis was diagnosed in 17,590 patients. The prevalence of endometriosis increased by 24 % from one in 1,191 patients in 2016 to one in 853 patients in 2020 (adjusted-odds ratio [aOR] 1.24, 95% confidence interval [CI] 1.19-1.30). Clinical and pregnancy characteristics that had greater than two-fold association to endometriosis included polycystic ovary syndrome, placenta previa, cesarean delivery, maternal age of ≥30 years, prior pregnancy loss, and anxiety disorder. Pregnant patients with endometriosis were more likely to have the diagnosis of measured severe maternal morbidity during the index hospitalization for delivery (47.8 vs 17.3 per 1,000 deliveries, aOR 1.91, 95%CI 1.78-2.06); these associations were more prominent following vaginal (aOR 2.82, 95%CI 2.41-3.30) compared to cesarean (aOR 1.85, 95%CI 1.71-2.00) deliveries. Among the individual morbidity indicators, endometriosis was most strongly associated with thromboembolism (aOR 5.05, 95%CI 3.70-6.91), followed by sepsis (aOR 2.39, 95%CI 1.85-3.09) and hysterectomy (aOR 2.18, 95%CI 1.85-2.56). When stratified for endometriosis anatomical site, odds of thromboembolism was increased in endometriosis at distant site (aOR 9.10, 95%CI 3.76-22.02) and adnexa (aOR 7.37, 95%CI 4.43-12.28); odds of sepsis was most increased in endometriosis at multi-classifier locations (aOR 7.33, 95%CI 2.93-18.31) followed by pelvic peritoneum (aOR 5.54, 95%CI 2.95-10.40); and odds of hysterectomy exceeded three-fold in endometriosis at adnexa (aOR 3.00, 95%CI 2.30-3.90), distant site (aOR 5.36, 95%CI 3.48-8.24), and multi-classifier location (aOR 4.46, 95%CI 2.11-9.41). CONCLUSION The results of this nationwide analysis suggest that pregnancy with endometriosis is uncommon but gradually increasing over time in the United States. The data also suggest that endometriosis during pregnancy is associated with increased risk of severe maternal morbidity at delivery, especially for thromboembolism, sepsis, and hysterectomy. These morbidity risks differed by the anatomical location of endometriosis.

JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2024; 46:102582.

Abstract
This population-based cohort evaluated the association between endometriosis and severe maternal morbidity (SMM), and the mediating effect of infertility and fertility treatment. Included were all singleton deliveries in Ontario between 2006 and 2014. Modified Poisson regression generated adjusted relative risks. Mediation analysis estimated the direct effect of endometriosis and indirect effect through infertility and mode of conception. 787 449 deliveries were included (19 099, 2.4% with endometriosis). SMM occurred in 29.0 per 1000 deliveries among women with endometriosis, in contrast to 18.2 per 1000 deliveries among those without endometriosis-corresponding to an adjusted relative risk of SMM of 1.43 (95% CI 1.31-1.56). Mediation analysis demonstrated that the effect of endometriosis on SMM was independent of infertility or fertility treatment. We conclude that SMM in women with endometriosis appears to be due to the disease itself and not to infertility or related treatments.

Fertil Steril 2024:S0015-0282(24)00511-9. [PMID: 38838806 DOI: 10.1016/j.fertnstert.2024.05.162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 05/27/2024] [Accepted: 05/28/2024] [Indexed: 06/07/2024]
Abstract
OBJECTIVE To determine whether obstetric outcomes differ between women with endometriosis and those without, where all women undergo first-trimester screening for endometriosis. DESIGN A prospective observational cohort study. SETTING The Early Pregnancy Unit at University College London Hospital, United Kingdom. PATIENTS Women with a live pregnancy progressing beyond 12 weeks' gestation and concurrent endometriosis (n = 110) or no endometriosis (n = 393). INTERVENTION All women underwent a pelvic ultrasound examination in early pregnancy to examine for the presence of endometriosis and uterine abnormalities. MAIN OUTCOME MEASURES The primary outcome of interest was preterm birth, defined as delivery before 37 completed weeks' gestation. Secondary outcomes included late miscarriage, antepartum hemorrhage, placental site disorders, gestational diabetes, hypertensive disorders of pregnancy, neonates small for gestational age, mode of delivery, intrapartum sepsis, postpartum hemorrhage, and admission to the neonatal unit. RESULTS Women with a diagnosis of endometriosis did not have statistically significantly higher odds of preterm delivery (adjusted odds ratio [aOR] 1.85 [95% confidence interval {CI} 0.50-6.90]), but they did have higher odds of postpartum hemorrhage during cesarean section (aOR 3.64 [95% CI 2.07-6.35]) and admission of their newborn infant to the neonatal unit (aOR 3.24 [95% CI 1.08-9.73]). Women with persistent or recurrent deep endometriosis after surgery also had higher odds of placental site disorders (aOR 8.65 [95% CI 1.17-63.71]) and intrapartum sepsis (aOR 3.47 [95% CI 1.02-11.75]). CONCLUSION We observed that women with endometriosis do not have higher odds of preterm delivery, irrespective of their disease subtype. However, they do have higher odds of postpartum hemorrhage during the cesarean section and newborn admission to the neonatal unit.

Abstract
BACKGROUND Preeclampsia (PE) is a pregnancy-specific disorder with complex pathogenesis. Cuproptosis is a novel identified form of programmed cell death, however, the link between cuproptosis and clinical outcomes in PE is still not fully understood. In this study, we searched for cuproptosis-related genes (CRGs) in the placental tissues of normal and PE patients to clarify the importance of cuproptosis in the development of PE and provide potential predictive indicators for the occurrence of PE. METHODS Using RNA sequencing data in the GEO database, we conducted functional enrichment analysis of Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Set Enrichment Analysis (GSEA), supported by linear regression model and operating characteristic curve (ROC) curve analysis, and summarized the role of CRGs in preeclampsia. RESULTS A total of 2831 differentially expressed genes related to PE were screened through multiple database analyses. After further intersection with 19 reported CRGs, 5 CRGs have been closely associated with the pathogenesis of PE, including NFE2L2, PDHA1, PDHB, DLD and GLS. NFE2L2 was identified as a key central gene. Pearson correlation analysis showed that CRGs could be related to several maternal and fetal outcome factors, including the highest pregnancy blood pressure, placenta weight, umbilical blood flow pulsatility index (PI), and neonatal weight. Linear regression equation revealed that the expression of NFE2L2 is negatively correlated with the highest pregnancy blood pressure and umbilical blood flow PI but positively correlated with placental weight and neonatal weight. QRT-PCR showed that the expression of these CRGs was significantly lower in placental tissues. CONCLUSIONS This cuproptosis pattern may be a potential prognostic factor in patients with PE and could provide new insights into disease progression.
