Evaluation of menstrual symptoms after Coronavirus disease 2019 vaccination in women with endometriosis.

BACKGROUND: Vaccination can have an impact on menstruation, and this impact may be more notable in women with inflammatory gynecological pathologies such as endometriosis. OBJECTIVES: We aimed to investigate the impact of mRNA-based SARS-CoV-2 vaccines on menstrual cycle-related symptoms in women with endometriosis and assess the effect of hormonal therapy on potential SARS-CoV-2 vaccination-induced menstrual changes. DESIGN: A total of 848 women who received at least two doses of mRNA-based COVID-19 vaccines were prospectively recruited: 407 with endometriosis (endometriosis group) and 441 healthy controls (non-endometriosis group). METHODS: Data regarding demographics, clinical characteristics, hormonal treatment, and menstrual-associated symptoms in the first and second cycle after vaccination were collected through an online survey. RESULTS: A similar percentage of patients in both the endometriosis and the non-endometriosis group self-reported menstrual-associated changes the first (52.6% versus 48.8%, respectively) and second cycle after vaccination (29.0% versus 28.1%, respectively). Although the total symptoms recorded were not different between the two groups, several specific symptoms were statistically more frequent in the endometriosis group. These were pain disorders and fatigue in the first cycle after vaccination and pain disorders, menstrual headache and fatigue in the second cycle after vaccination. Bleeding frequency/regularity disorders were found to be more frequent in the non-endometriosis group in the first cycle after vaccination. Patients under hormonal treatment reported fewer changes in menstrual symptoms in the first and second cycle after vaccination compared with those not receiving this treatment. Similarly, patients in the endometriosis group receiving hormonal treatment reported fewer changes in menstrual-associated symptoms compared with those not following any hormonal treatment in the first and second menstrual cycle after the last vaccination. CONCLUSION: Women with endometriosis immunized with mRNA-based SARS-CoV-2 vaccines did not perceive greater worsening or new menstrual-associated symptoms after complete COVID-19 vaccination compared with healthy controls. Hormonal treatment may have a protective effect against worsened or new menstrual symptoms induced by COVID-19 vaccination.

Impact of SARS-COV2 Pandemic on Patients with Endometriosis and Their Health Care.

Background: Endometriosis is a debilitating chronic inflammatory disease. The current SARS-COV2 pandemic has had an impact on the management of these patients. Tele-health care has been a relevant tool. The aim of this study was to analyze the impact of the SARS-COV2 pandemic on the perceived clinical health status and the type of care received in patients with endometriosis. Materials and Methods: We evaluated 945 premenopausal women treated at the Hospital Clinic of Barcelona between October 1 and December 31, 2020. Five hundred forty-nine women had endometriosis, and 396 had other benign gynecological diseases. An online health survey was sent to these patients. Clinicopathological features data were recorded. Results: Compared to patients with other benign gynecological diseases, a higher proportion of patients with endometriosis reported worsening of their symptoms (148/549, 27% vs. 85/396, 21.5%) and concern about their disease (515/549, 93.8% vs. 342/396, 86.4%), and more frequently received tele-health care (73.8% vs. 54.0%) during the pandemic. Patients with endometriosis and "significant" pelvic pain reported more concern and worsening than patients without "significant" pelvic pain, and evaluated the assistance received poorly. Multivariate analysis showed pelvic pain, limitation in usual activity, and sadness as risk factors of perception of disease worsening. Awaiting surgery and the feeling of sadness were risk factors of concern. Conclusions: Patients with endometriosis, and especially patients with "significant" pelvic pain, reported greater concern and the perception of worsening during the SARS-COV2 pandemic. Tele-health is a useful tool in patients with endometriosis, and face-to-face visit should be considered in those reporting "significant" pelvic pain.
