Impact of endometriosis on obstetric outcome after natural conception: a multicenter Italian study.

PURPOSE: To evaluate obstetric outcome in women with endometriosis who conceive naturally and receive standard obstetric care in Italy. METHODS: Cases were consecutive women with endometriosis managed in eleven Italian referral centers. Controls were women in whom endometriosis was excluded. All women filled in a questionnaire addressing previous natural pregnancies. Marginal logistic regression models were fitted to evaluate the impact of endometriosis on obstetric outcome. A post hoc analysis was performed within the endometriosis group comparing women with severe adenomyosis versus women with absent or mild adenomyosis. RESULTS: Three hundred and fifty-five pregnancies in endometriosis group and 741 pregnancies in control group were included. Women with endometriosis had a higher risk of preterm delivery < 34 weeks (6.4% vs 2.8%, OR 2.42, 95% CI 1.22-4.82), preterm delivery < 37 weeks (17.8% vs 9.7%, OR 1.98, 95% CI 1.23-3.19), and neonatal admission to Intensive Care Unit (14.1% vs 7.0%, OR 2.04, 95% CI 1.23-3.36). At post hoc analysis, women with endometriosis and severe adenomyosis had an increased risk of placenta previa (23.1% vs 1.8%, OR 16.68, 95% CI 3.49-79.71), cesarean delivery (84.6% vs 38.9%, OR 8.03, 95% CI 1.69-38.25) and preterm delivery < 34 weeks (23.1% vs 5.7%, OR 5.52, 95% CI 1.38-22.09). CONCLUSION: Women with endometriosis who conceive naturally have increased risk of preterm delivery and neonatal admission to intensive care unit. When severe adenomyosis is coexistent with endometriosis, women may be at increased risk of placenta previa and cesarean delivery. TRIAL REGISTRATION: Clinical trial registration number: NCT03354793.

Efficacy of dienogest in improving pain in women with endometriosis: a 12-month single-center experience.

PURPOSE: Dienogest has recently been marketed as a medical treatment for endometriosis. Given the recent introduction on the market of Dienogest, little data are available regarding its effectiveness in routine clinical practice. METHODS: The study is an observational, single-center, cohort study. Eligible was women with a surgical diagnosis of endometriosis dating back <24 months or a clinical/instrumental diagnosis of endometriosis and endometriosis-associated pelvic pain score of at least 40 mm on a 100-mm visual analog scale (VAS) at start of treatment and who had been taking Dienogest 2 mg once daily treatment at the time of study entry for no more than 30 days, consecutively observed between September 2013 to September 2014. In accordance with routine practice, women came back for clinical assessment and evaluation of pain after 1 (V1), 3 (V2), and 12 (V3) months. RESULTS: A total of 132 women were enrolled in the study. A total of 21 of the enrolled patients were released from the study during follow-up due to adverse effects. The mean pelvic pain VAS score at baseline was 8.9 (SD 1.3). The corresponding values were 6.7 (SD 3.2) and 5.7 (SD 3.7) for dyspareunia and dyschezia. The mean VAS scores progressively and significantly decreased to 0.9 (SD 1.6) for pelvic pain, 1.4 (SD 2.1) for dyspareunia and 0.2 (SD 0.9) for dyschezia, respectively, 12 months after start of treatment. CONCLUSION: This study confirms that in routine clinical practice, Dienogest 2 mg is an effective and well-tolerated treatment for endometriosis-related pain in women with endometriosis.
