11. Effects of SARS-CoV-2 strain variation on virus neutralisation titres: therapeutic use of convalescent plasma

Author

Abstract

We compared neutralising antibody titres of convalescent samples collected before and after the emergence of novel strains of SARS-CoV-2, against the wild-type virus (WT), Alpha (B.1.1.7) and Beta (B.1.351) variants. Plasma collected in 2020 before emergence of variants showed reduced titres against the Alpha variants, and both sets of samples demonstrated significantly reduced titres against Beta. Comparison of microneutralisation titres to those obtained with pseudotype and HAT assays showed a good correlation of titres and effects of strain variation, supporting the use of these simpler assays for assessment of convalescent plasma potency against currently circulating and emerging strains of SARS-CoV-2.

Abstract

Background Convalescent plasma containing neutralising antibody to SARS-CoV-2 is under investigation for COVID-19 treatment. We report diverse virological characteristics of UK intensive care patients enrolled in the Immunoglobulin Domain of the REMAP-CAP randomised controlled trial that potentially influence treatment outcomes. Methods SARS-CoV-2 RNA in nasopharyngeal swabs collected pre-treatment was quantified by PCR. Antibody status was determined by spike-protein ELISA. B.1.1.7 was differentiated from other SARS-CoV-2 strains using allele-specific probes or restriction site polymorphism (SfcI) targeting D1118H. Results Of 1274 subjects, 90% were PCR-positive with viral loads 118-1.7x10 11 IU/ml. Median viral loads were 40-fold higher in those seronegative for IgG antibodies (n=354; 28%) compared to seropositives (n=939; 72%). Frequencies of B.1.1.7 increased from

Abstract

Metagenomic high-throughput sequencing (mHTS) is a hypothesis-free, universal pathogen detection technique for determination of the DNA/RNA sequences in a variety of sample types and infectious syndromes. mHTS is still in its early stages of translating into clinical application. To support the development, implementation and standardization of mHTS procedures for virus diagnostics, the European Society for Clinical Virology (ESCV) Network on Next-Generation Sequencing (ENNGS) has been established. The aim of ENNGS is to bring together professionals involved in mHTS for viral diagnostics to share methodologies and experiences, and to develop application recommendations. This manuscript aims to provide practical recommendations for the wet lab procedures necessary for implementation of mHTS for virus diagnostics and to give recommendations for development and validation of laboratory methods, including mHTS quality assurance, control and quality assessment protocols.

Abstract

Item does not contain fulltext, IMPORTANCE: The evidence for benefit of convalescent plasma for critically ill patients with COVID-19 is inconclusive. OBJECTIVE: To determine whether convalescent plasma would improve outcomes for critically ill adults with COVID-19. DESIGN, SETTING, AND PARTICIPANTS: The ongoing Randomized, Embedded, Multifactorial, Adaptive Platform Trial for Community-Acquired Pneumonia (REMAP-CAP) enrolled and randomized 4763 adults with suspected or confirmed COVID-19 between March 9, 2020, and January 18, 2021, within at least 1 domain; 2011 critically ill adults were randomized to open-label interventions in the immunoglobulin domain at 129 sites in 4 countries. Follow-up ended on April 19, 2021. INTERVENTIONS: The immunoglobulin domain randomized participants to receive 2 units of high-titer, ABO-compatible convalescent plasma (total volume of 550 mL ± 150 mL) within 48 hours of randomization (n = 1084) or no convalescent plasma (n = 916). MAIN OUTCOMES AND MEASURES: The primary ordinal end point was organ support-free days (days alive and free of intensive care unit-based organ support) up to day 21 (range, -1 to 21 days; patients who died were assigned -1 day). The primary analysis was an adjusted bayesian cumulative logistic model. Superiority was defined as the posterior probability of an odds ratio (OR) greater than 1 (threshold for trial conclusion of superiority >99%). Futility was defined as the posterior probability of an OR less than 1.2 (threshold for trial conclusion of futility >95%). An OR greater than 1 represented improved survival, more organ support-free days, or both. The prespecified secondary outcomes included in-hospital survival; 28-day survival; 90-day survival; respiratory support-free days; cardiovascular support-free days; progression to invasive mechanical ventilation, extracorporeal mechanical oxygenation, or death; intensive care unit length of stay; hospital length of stay; World Health Organization ordinal scale score at day 14; venous thromb

Background: Convalescent plasma has been widely used to treat COVID-19 and is under investigation in numerous randomized clinical trials, but results are publicly available only for a small number of trials. The objective of this study was to assess the benefits of convalescent plasma treatment compared to placebo or no treatment and all-cause mortality in patients with COVID-19, using data from all available randomized clinical trials, including unpublished and ongoing trials (Open Science Framework, https://doi.org/10.17605/OSF.IO/GEHFX). Method(s): In this collaborative systematic review and meta-analysis, clinical trial registries (ClinicalTrials.gov, WHO International Clinical Trials Registry Platform), the Cochrane COVID-19 register, the LOVE database, and PubMed were searched until April 8, 2021. Investigators of trials registered by March 1, 2021, without published results were contacted via email. Eligible were ongoing, discontinued and completed randomized clinical trials that compared convalescent plasma with placebo or no treatment in COVID-19 patients, regardless of setting or treatment schedule. Aggregated mortality data were extracted from publications or provided by investigators of unpublished trials and combined using the Hartung-Knapp-Sidik-Jonkman random effects model. We investigated the contribution of unpublished trials to the overall evidence. Result(s): A total of 16,477 patients were included in 33 trials (20 unpublished with 3190 patients, 13 published with 13,287 patients). 32 trials enrolled only hospitalized patients (including 3 with only intensive care unit patients). Risk of bias was low for 29/33 trials. Of 8495 patients who received convalescent plasma, 1997 died (23%), and of 7982 control patients, 1952 died (24%).

Abstract

Metagenomic high-throughput sequencing (mHTS) is a hypothesis-free, universal pathogen detection technique for determination of the DNA/RNA sequences in a variety of sample types and infectious syndromes. mHTS is still in its early stages of translating into clinical application. To support the development, implementation and standardization of mHTS procedures for virus diagnostics, the European Society for Clinical Virology (ESCV) Network on Next-Generation Sequencing (ENNGS) has been established. The aim of ENNGS is to bring together professionals involved in mHTS for viral diagnostics to share methodologies and experiences, and to develop application recommendations. This manuscript aims to provide practical recommendations for the wet lab procedures necessary for implementation of mHTS for virus diagnostics and to give recommendations for development and validation of laboratory methods, including mHTS quality assurance, control and quality assessment protocols.

Abstract

Infection with hepatitis E virus (HEV) can be clinically inapparent or produce symptoms and signs of hepatitis of varying severity and occasional fatality. This variability in clinical outcomes may reflect differences in host susceptibility or the presence of virally encoded determinants of pathogenicity. Analysis of complete genome sequences supports the division of HEV genotype 3 (HEV-3) variants into three major clades: 3ra comprising HEV isolates from rabbits, and 3efg and 3abchij comprising the corresponding named subtypes derived from humans and pigs. Using this framework, we investigated associations between viral genetic variability of HEV-3 in symptomatic and asymptomatic infections by comparing HEV-3 subgenomic sequences previously obtained from blood donors with those from patients presenting with hepatitis in the UK (54 blood donors, 148 hepatitis patients), the Netherlands (38 blood donors, 119 hepatitis patients), France (24 blood donors, 55 hepatitis patients) and Germany (14 blood donors, 36 hepatitis patients). In none of these countries was evidence found for a significant association between virus variants and patient group (P>0.05 Fisher's exact test). Furthermore, within a group of 123 patients in Scotland with clinically apparent HEV infections, we found no evidence for an association between variants of HEV-3 and disease severity or alanine aminotransferase level. The lack of detectable virally encoded determinants of disease outcomes in HEV-3 infection implies a more important role for host factors in its clinical phenotype.

Abstract

Improved understanding of the early adaptation of zoonotic, human-infective RNA viruses and the genetic factors leading to spillover will inform public health approaches attempting to limit the morbidity and mortality associated with these events. In this thesis, I use clinical microbiological methods to characterize the intra-host replicative and evolutionary dynamics of SARS-CoV-2 and bioinformatic approaches to investigate genetic factors associated with spillover of arboviruses. Chapter one broadly reviews the field of virology. Chapter two reviews the apolipoprotein B mRNA-editing enzyme, catalytic polypeptide (APOBEC) family of proteins, focusing on their emergence, diversification, and function, and summarizes the bioinformatic and functional evidence of their role in SARS-CoV-2 evolution. Chapter three details the methods underlying the subsequent results chapters. Chapter four describes the development and validation of single nucleotide polymorphism-based genotyping assays for identifying variants of concern in COVID-19 clinical samples. Their performance is compared to next-generation sequencing, demonstrating the superiority of the genotyping assays at a wide range of viral loads. Chapter five uses amplification data generated from two COVID-19 clinical trials to explore factors associated with viral load and within-patient viral load dynamics, uses a novel polymerase chain reaction approach to quantify subgenomic RNA transcripts, and investigates the emergence and spread of the Alpha variant in the United Kingdom and the Zeta, Gamma, and Delta variants in Brazil. Chapter six investigates the interaction between SARS-CoV-2 virological features and COVID-19 clinical outcomes leveraging patients admitted to intensive care within the REMAP-CAP convalescent plasma clinical trial. The null results in this chapter support severe COVID-19 pathology being primarily immune-mediated. Chapter seven quantitatively tests the hypothesis that convalescent plasma treatment was responsible for the emergence of SARS-CoV-2 variants of concern using an intensively sampled cohort within the REMAP-CAP convalescent plasma trial. Using a variety of approaches, no evidence in support of convalescent plasma therapy as a general driver of immune-escape substitutions was found. Chapter eight probes the genetic factors associated with human-human transmissibility of arboviruses, finding strong evidence for the role of CpG suppression in the host optimization of flaviviruses. The strong genetic barriers to spillover enable more focused surveillance of this informal classification of viruses.
