Emergency department presentation varies widely, suggesting that distinct clinical phenotypes exist and, importantly, that these distinct phenotypic presentations may respond differently to treatment. A single shot of one of the currently authorized COVID-19 vaccines may be sufficient to provide immunity to individuals who have previously been infected by the virus, thus eliminating the need for a second dose and helping to stretch severely limited vaccine supplies, a study from Mount Sinai has f... Medical Xpress - Medical and Health News The experiments also shed light on key processes the coronavirus uses to infect different cells and found that the antiviral drug remdesivir, which has an FDA Emergency Use Authorization for treating COVID-19, does appear to work against the virus in cell-culture tests on respiratory cells, whereas hydroxychloroquine does not.

Asheville resident Ashley M., who asked Xpress not to publish her full name to protect sensitive health information, has managed to hang onto her job since contracting COVID-19. Most patients included in the study (613 patients, or 60 percent) presented with what the researchers dubbed "phenotype II." "Our discoveries here suggest new avenues for therapeutic interventions against COVID-19, and also underscore the importance of testing candidate drugs in respiratory cells," said co-senior author Sara Cherry, Ph.D., a professor of Pathology and Laboratory Medicine and scientific director of the High-Throughput Screening (HTS) Core at Penn Medicine. A single shot of one of the currently authorized COVID-19 vaccines may be sufficient to provide immunity to individuals who have previously been infected by the virus, thus eliminating the need for a second dose and helping to stretch severely limited vaccine supplies, a study from Mount Sinai has found. Since SARS-CoV-2 is mainly a respiratory virus and is thought to initiate infections via airway-lining cells, the researchers sought a respiratory cell type that they could infect experimentally with the virus.

In the course of universal admission screening with the Cepheid Xpert Xpress SARS-CoV-2 assay at our institution, we observed that 3.9 % (44/1123) of SARS-CoV-2 positive results were negative for the envelope (E) gene target but positive for the nucleocapsid (N2) target. The findings suggest that in kidney and liver cells, the virus uses a mechanism that can be disrupted, for example, by hydroxychloroquine; yet the virus appears to use a different mechanism in respiratory cells, thus explaining hydroxychloroquine's lack of success in those cells—and in COVID-19 clinical trials. In contrast to many prior studies, the screens tested the molecules for anti-coronaviral activity in a variety of cell types, including human airway-lining cells that are similar to the ones principally affected in COVID-19. Hydroxychloroquine, which is used as a malaria drug, and remdesivir, were effective in both cell types. Your opinions are important to us.
