Background: Anti-SARS-CoV-2 virus antibody levels in convalescent plasma (CP), which may be useful in severe Anti-SARS-CoV-2 virus infections, have been rarely reported.
Results: A total of eight donors were considered for enrollment; two of them were excluded because of ineligible routine check. Of the six remaining participants, five samples were tested weakly positive by the IgM ELISA. Meanwhile, high titers of IgG were observed in five samples. The patient treated with CP did not require mechanical ventilation 11 days after plasma transfusion, and was then transferred to a general ward.
Conclusions: Our serological findings in convalescent plasma from recovered patients may help facilitate understanding of the SARS-CoV-2 infection and establish CP donor screening protocol in COVID-19 outbreak.
Methods: Anti-SARS-CoV-2 antibodies including IgM and IgG were measured by two enzyme-linked immunosorbent assays (ELISA) in convalescent plasma from six donors who have recovered from coronavirus disease 2019 (COVID-19) in Nanjing, China. CP was also utilized for the treatment of one severe COVID-19 patient.

The generalisability of critical illness molecular phenotypes to low- and middle-income countries (LMICs) is unknown. We show that molecular phenotypes derived in high-income countries (hyperinflammatory and hypoinflammatory, reactive and uninflamed) stratify sepsis patients in Uganda by physiological severity, mortality risk and dysregulation of key pathobiological domains. A classifier model including data available at the LMIC bedside modestly discriminated phenotype assignment (area under the receiver operating characteristic curve (AUROC) 0.

Background And Objectives: Apheresis platelets products and plasma are essential for medical interventions, but both still have inherent risks associated with contamination and viral transmission. Platelet products are vulnerable to bacterial contamination due to storage conditions, while plasma requires extensive screening to minimize virus transmission risks. Here we investigate rapid irradiation to sterilizing doses for bacteria and viruses as an innovative pathogen reduction technology.

Convalescent plasma therapy (CPT) is one of the treatment modalities used for COVID-19. Initial smaller studies showed the usefulness of CPT in COVID-19, but larger studies showed that it is not effective. This is a retrospective observational study conducted between 1st June 2020 and 31st July 2021 at a tertiary hospital in Noida, India.

Lassa virus, the cause of deadly Lassa fever, is endemic in West Africa, where thousands of cases occur on an annual basis. Nigeria continues to report increasingly severe outbreaks of Lassa Fever each year and there are currently no approved vaccines or therapeutics for the prevention or treatment of Lassa Fever. Given the high burden of disease coupled with the potential for further escalation due to climate change the WHO has listed Lassa virus as a priority pathogen with the potential to cause widespread outbreaks.

Objective: This study compared the outcomes of two cohorts of patients with coronavirus disease 2019 (COVID-19) who received COVID-19 convalescent plasma transfusions between 2020 and 2021.
Methods: This retrospective study was conducted at a tertiary hospital in São Paulo, Brazil. We included a retrospective cohort of patients who received convalescent compassionate plasma, and another group of patients from a previous clinical study.
