Sickle cell disease and COVID-19 in pregnant women.

INTRODUCTION: The effect of coronavirus disease (COVID-19) on pregnancy outcome in women with sickle cell disease (SCD) is unknown. OBJECTIVES: To analyze the severity of the SARS-CoV-2 infection in pregnant women with SCD and its impact on pregnancy. METHODS: This retrospective cohort study included SCD pregnant women tested positive for COVID-19 between March 2020 - February 2021. The primary endpoint was the severity of the COVID-19 infection. Secondary endpoints were pregnancy complications and fetal outcomes. RESULTS: During the study period among 82 pregnant women with SCD, 8 have presented symptoms suggestive of COVID-19 and were tested positive. A common mild clinical presentation was observed in 6 women (75%), one woman was asymptomatic and one required oxygen. The latter was admitted to the Intensive Care Unit and a cesarean section was performed in the context of an ongoing vaso-occlusive crisis and acute chest syndrome together with incidental preeclampsia. Labor was induced in another patient who developed a vaso-occlusive crisis after COVID-19 remission. Fetal outcomes were good with an average Apgar score of 10 and normal umbilical blood pH at birth. Two newborns were small-for-gestational-age as expected on the ultrasound follow-up before occurrence of COVID-19. CONCLUSION: COVID-19 infection in our population of pregnant women with SCD had typical presentation and rarely triggered a sickle cell crisis or other complications. Fetal outcomes were good and did not seem to be directly influenced by the SARS-CoV-2 virus. Further studies are required to confirm these observations as compared to the population of women with SCD without COVID-19 infection.

Mild COVID-19 infection does not alter the ovarian reserve in women treated with ART.

RESEARCH QUESTION: Does mild COVID-19 infection affect the ovarian reserve of women undergoing an assisted reproductive technology (ART) protocol? DESIGN: A prospective observational study was conducted between June and December 2020 at the ART unit of Tenon Hospital, Paris. Women managed at the unit for fertility issues by in-vitro fecundation, intracytoplasmic sperm injection (IVF/ICSI), fertility preservation, frozen embryo transfer or artificial insemination, and with an anti-Müllerian hormone (AMH) test carried out within 12 months preceding ART treatment, were included. All the women underwent a COVID rapid detection test (RDT) and AMH concentrations between those who tested positive (RDT positive) and those who tested negative (RDT negative). RESULTS: The study population consisted of 118 women, 11.9% (14/118) of whom were COVID RDT positive. None of the tested women presented with a history of severe COVID-19 infection. The difference between the initial AMH concentration and AMH concentration tested during ART treatment was not significantly different between the COVID RDT positive group and COVID RDT negative group (-1.33 ng/ml [-0.35 to -1.61) versus -0.59 ng/ml [-0.15 to -1.11], P = 0.22). CONCLUSION: A history of mild COVID-19 infection does not seem to alter the ovarian reserve as evaluated by AMH concentrations. Although these results are reassuring, further studies are necessary to assess the effect of COVID-19 on pregnancy outcomes in women undergoing ART.
