COVID-19 vaccination may cause temporary menstrual disturbances in adolescent girls ChildHealth Coronavirus Disease COVID MenstrualPain Menstruation Folkehelseinst
By Dr. Sanchari Sinha Dutta, Ph.D.Dec 6 2022Reviewed by Benedette Cuffari, M.Sc. A study recently published in the journal Vaccine describes the risk of menstrual disturbances in adolescent girls aged 12-15 years after receiving the Pfizer-BioNTech messenger ribonucleic acid -based coronavirus disease 2019 vaccine.
In both clinical trials and real-world situations, most COVID-19 vaccines have shown considerable efficacy in reducing SARS-CoV-2 infection, severe COVID-19, hospitalization, and mortality rates. The most commonly reported side effects of vaccination include injection site pain, fatigue, and headache.
Study design The current study is a part of an ongoing population-based pregnancy cohort study established by the Norwegian Institute of Public Health. Menstrual disturbances Drug Discovery eBook Compilation of the top interviews, articles, and news in the last year. Download a free copy Menstrual disturbances were commonly observed among the study participants, irrespective of their vaccination and infection status. Among vaccinated participants, about 22% reported one or more disturbances in their last period before vaccination.
The association between COVID-19 vaccination and menstrual disturbances was further analyzed using appropriate statistical methods. To this end, vaccination was found to be associated with an increased risk of heavy bleeding, prolonged bleeding, shorter between-period interval, longer between-period interval, and stronger period pain. These risks were similar in vaccinated participants with and without previous SARS-CoV-2 infection.

Epigenetic and transcriptomic reprogramming in monocytes of severe COVID-19 patients reflects alterations in myeloid differentiation and the influence of inflammatory cytokines - Genome MedicineBackground COVID-19 manifests with a wide spectrum of clinical phenotypes, ranging from asymptomatic and mild to severe and critical. Severe and critical COVID-19 patients are characterized by marked changes in the myeloid compartment, especially monocytes. However, little is known about the epigenetic alterations that occur in these cells during hyperinflammatory responses in severe COVID-19 patients. Methods In this study, we obtained the DNA methylome and transcriptome of peripheral blood monocytes from severe COVID-19 patients. DNA samples extracted from CD14 + CD15- monocytes of 48 severe COVID-19 patients and 11 healthy controls were hybridized on MethylationEPIC BeadChip arrays. In parallel, single-cell transcriptomics of 10 severe COVID-19 patients were generated. CellPhoneDB was used to infer changes in the crosstalk between monocytes and other immune cell types. Results We observed DNA methylation changes in CpG sites associated with interferon-related genes and genes associated with antigen presentation, concordant with gene expression changes. These changes significantly overlapped with those occurring in bacterial sepsis, although specific DNA methylation alterations in genes specific to viral infection were also identified. We also found these alterations to comprise some of the DNA methylation changes occurring during myeloid differentiation and under the influence of inflammatory cytokines. A progression of DNA methylation alterations in relation to the Sequential Organ Failure Assessment (SOFA) score was found to be related to interferon-related genes and T-helper 1 cell cytokine production. CellPhoneDB analysis of the single-cell transcriptomes of other immune cell types suggested the existence of altered crosstalk between monocytes and other cell types like NK cells and regulatory T cells. Conclusion Our findings show the occurrence of an epigenetic and transcriptional reprogramming of peripheral blood monocytes, which could be associated with the
