ABSTRACT
OBJECTIVE: To investigate the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA BNT162b2 vaccine on women's menstrual cycle. METHODS: In this questionnaire-based cross-sectional study, we assessed menstrual pattern and changes in women who completed the SARS-CoV-2 mRNA BNT162b2 vaccine 3 months before and after receiving the vaccine. Included were women aged 18-50 years without known gynecologic comorbidities who regularly monitor their menstruation through electronic calendars. All participants competed a detailed questionnaire on their menstrual symptoms including information on any irregular bleeding. To minimize bias, each woman served as a self-control before and after vaccination. Primary outcome was rate of irregular bleeding following vaccination and secondary outcome was presence of any menstrual change, including irregular bleeding, mood changes, or dysmenorrhea following the vaccine. RESULTS: A total of 219 women met the inclusion critieria. Of them, 51 (23.3%) experienced irregular bleeding following the vaccine. Almost 40% (n = 83) of study participants reported any menstrual change following vaccination. Parity was positively asssociated with irregular bleeding with 26 (50%) of those suffering from irregular bleeding being multiparous compared with only 53 (31.5%) of women with no irregular bleeding (nulliparous 46% vs 60%, multiparous 50% vs 31%, rest 4% vs 8%, P = 0.049). The presence of medical comorbidities was also significantly higher among patients who experienced irregular bleeding (20.0% vs 6.0%, P = 0.003). CONCLUSION: Our study shows relatively high rates of irregular bleeding and menstrual changes after receiving the SARS-CoV-2 mRNA BNT162b2 vaccine. Further research is needed to confirm our findings and to better characterize the magnitude of change and any possible long-term implications.
ABSTRACT
PURPOSE: As the use of the messenger RNA (mRNA) BNT162b2 (Pfizer-BioNTech) Coronavirus disease 2019 vaccine has grown, reports on menstrual changes have arisen. We aimed to examine menstrual bleeding patterns and endometriosis-associated symptoms after receiving the mRNA BNT162b2 SARS-CoV-2 vaccine in women with endometriosis, as compared to the control group. METHODS: This is a questionnaire-based cross-sectional study including a total of 174 women. The study group included 86 women with a confirmed diagnosis of endometriosis and the control group included 88 women with no diagnosis or suspected diagnosis of endometriosis. Each woman completed a questionnaire on menstrual bleeding patterns and endometriosis-associated symptoms before and after receiving two doses of the BNT162b2 vaccine. Primary outcomes were changes in amount or length of menstrual bleeding, rates of intermenstrual bleeding and worsening in dysmenorrhea in the endometriosis patient group, as compared to the control group. Secondary outcomes included changes in all endometriosis-associated symptoms. RESULTS: In our cohort, women with endometriosis were more likely to experience changes in bleeding patterns (women with endometriosis: 39.5%, control group: 31.0%, p = 0.02), and a significant worsening in endometriosis-associated symptoms with an almost 4.3-fold worsening in dysmenorrhea [95% CI 1.9-9.9, p < 0.01] and 5.5-fold odds for any worsening in symptoms in endometriosis patients, as compared to the control group [95% CI 2.7-11.1, p < 0.01]. CONCLUSION: In our cohort, endometriosis was shown to be a significant risk factor for worsening of menstrual symptoms, after receiving the SARS-CoV-2 BNT162b2 mRNA vaccine. Further research is needed to confirm these findings.
ABSTRACT
OBJECTIVE: To assess the impact of the COVID-19 pandemic on the activity of a tertiary fertility service and compare telemedicine and face-to-face meetings during this time. METHODS: This was a retrospective cohort study conducted in a university affiliated tertiary medical center. Included were patients scheduled for an appointment in the in-vitro fertilization (IVF) unit between March 18th and April 15th. A comparison was made between patients who chose telemedicine as opposed to face-to-face meetings. Additionally, the population of patients who chose to cancel their appointment was characterized. IVF cycle outcomes were additionally compared between the groups. RESULTS: Overall, 90 IVF clinic appointments were scheduled during the study period. Thirty-four (37.8 %) patients chose to arrive to the clinic in spite of the COVID 19 pandemic and partial quarantine, 27 (30.0 %) patients chose to avoid in person meeting and scheduled a telemedicine appointment and 29 (32.2 %) patients cancelled their appointment. On comparison between patients who chose telemedicine vs. face-to-face meeting, the telemedicine group had lower prevalence of primary infertility (20.0 % vs. 47.1 %, p = 0.037) and higher rates of preimplantation genetic testing indication for in-vitro fertilization (48.2 % vs. 20.6 %, p = 0.026). Rate of a first-ever clinic visit was higher in patients that arrived for a face-to-face meeting, as compared to telemedicine encounter (55.9 % vs. 28.0 %, respectively; p = 0.036). Patients that opted to avoid attending the clinic or meeting via telemedicine had higher rates of medical comorbidities compared to patients who chose to attend their appointment (51.7 % vs. 29.5 %, p = 0.016). Rate of appointments that led to fresh or frozen-thawed embryo transfer and these transfers' outcomes (clinical pregnancy rate) were similar in the telemedicine and face-to-face meeting groups (72.2 % vs. 88.0 % and 30.8 % vs. 31.8 %, p = 0.73 and p = 1.00; respectively). CONCLUSION: Telemedicine is a valuable tool for delivering fertility care during the COVID-19 pandemic. There is need to determine which patients will benefit most from this modality.
