Sex Differences in the Coronavirus Disease 2019

ABSTRACT: There are profound sex differences in coronavirus disease 2019 (COVID-19) outcomes, with higher morbidity and mortality in males compared to females. The possible mechanisms implicated in this sex bias include the direct effects of sex hormones on the innate and adaptive immune systems, as well as the differential activity of immune-related genes in sex chromosomes. These male-female differences in COVID-19 outcomes highlight the need for sex-disaggregated data to elaborate effective public health policies and the importance of including biological sex as a key variable in future therapeutic and vaccine trials.

Endometrial gene expression differences in women with coronavirus disease 2019

Project description:Objective: To study the potential effect of COVID-19 on the endometrium of affected symptomatic women. Design: Preliminary study of the endometrial transcriptomes in women with COVID-19 through RNA sequencing. Setting: Hospital and university laboratories. Subjects: Women with COVID-19 lacking SARS-CoV-2 infection in endometrial tissue. Intervention/Exposure: Endometrial biopsy collection. Main outcomes measures: Endometrial gene expression and functional analysis of patients with COVID-19 versus uninfected individuals. Results: COVID-19 systemic disease alters endometrial gene expression in 75% of women, with patients exhibiting a preponderance of 163 up-regulated (e.g., UTS2, IFI6, IFIH1, BNIP3) and 72 down-regulated genes (e.g., CPZ, CDH3, IRF4) (FDR<0.05). A total of 161 dysregulated functions (36 up-regulated and 125 down-regulated) were typically enriched in COVID-19 endometria, including upregulation in pathways involved in response to virus and cytokine inflammation, highlighting upregulation of a COVID-19 response pathway. Conclusion: COVID-19 affects endometrial gene expression despite the absence of SARS-CoV-2 particles in endometrial tissues.
