There is increasing evidence that coronavirus disease 2019 (COVID-19) produces more severe symptoms and higher mortality among men than women1–5. However, whether immune responses against acute respiratory syndrome (SARS-CoV-2) differ between sexes, such differences correlate with the sex difference in course of COVID-19, currently unknown. Here we examined viral loads, SARS-CoV-2-specific antibody titres, plasma cytokines blood-cell phenotyping patients moderate COVID-19 who had not...
Abstract Rapid and accurate SARS-CoV-2 diagnostic testing is essential for controlling the ongoing COVID-19 pandemic. The current gold standard diagnosis real-time RT-PCR detection of from nasopharyngeal swabs. Low sensitivity, exposure risks to healthcare workers, global shortages swabs personal protective equipment, however, necessitate validation new approaches. Saliva a promising candidate diagnostics because (1) collection minimally invasive can reliably be self-administered (2) saliva...
Abstract Although microbial populations in the gut microbiome are associated with COVID-19 severity, a causal impact on patient health has not been established. Here we provide evidence that dysbiosis is translocation of bacteria into blood during COVID-19, causing life-threatening secondary infections. We first demonstrate SARS-CoV-2 infection induces mice, which correlated alterations to Paneth cells and goblet cells, markers barrier permeability. Samples collected from 96 patients at two...
As Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) continues to spread, characterization of its antibody epitopes, emerging strains, related coronaviruses, and even the human proteome in naturally infected patients can guide development effective vaccines therapies. Since traditional epitope identification tools are dependent upon pre-defined peptide sequences, they not readily adaptable diverse viral proteomes. The Serum Epitope Repertoire Analysis (SERA) platform leverages a...
Significance Chilblain diagnoses have increased during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and been attributed to viral infection a subsequent robust antiviral immune response. As result, providers managed these cases differently than idiopathic chilblains, which are associated with cold exposure. The relationship between chilblains SARS-CoV-2 infection, however, remains unclear as most patients do not test positive for SARS-CoV-2–specific PCR or...
Abstract Background Initial CDC recommendations for passive monitoring of COVID-19 related symptoms among staff may not be sufficient in preventing the introduction and transmission SARS-CoV-2 healthcare settings. We therefore implemented active infection workers (HCWs) at an academic medical center during epidemic northeast US. Methods recruited a cohort HCWs Yale New Haven Hospital who worked units did have between March 28 June 1, 2020. During follow-up, participants provided daily...
17505 Background: Autologous stem-cell transplantation has become a widely used therapy in Hodgkin's disease. We analysed outcome, overall survival (OS) and time to progression (TTP) relapsed patients with disease undergoing autologous (ASCT) single institution. Methods: Between 1996 2006, 28 (19 males 9 females; median age 31 years old, range 10–63) underwent high dose chemotherapy CVB regimen (cyclophosphamide 6 gr/m 2 , VP-16 2.400 mg/m BCNU 450 ) support. Before transplantation, 20 had...
