“…For these exploratory analyses, 13 uncontrolled large case series without individual patient data enrolling 358 participants were included in descriptive analysis . In this study, 125 case reports or case series enrolling 265 participants were included for patient-level exploratory analyses. One study was included in both the descriptive analysis and the individual patient data analysis because individual patient data were available only for a subgroup of patients.…”

ImportancePatients who are immunocompromised have increased risk for morbidity and mortality associated with coronavirus disease 2019 (COVID-19) because they less frequently mount antibody responses to vaccines. Although neutralizing anti-spike monoclonal-antibody treatment has been widely used to treat COVID-19, evolutions of SARS-CoV-2 have been associated with monoclonal antibody-resistant SARS-CoV-2 variants and greater virulence and transmissibility of SARS-CoV-2. Thus, the therapeutic use of COVID-19 convalescent plasma has increased on the presumption that such plasma contains potentially therapeutic antibodies to SARS-CoV-2 that can be passively transferred to the plasma recipient.ObjectiveTo assess the growing number of reports of clinical experiences of patients with COVID-19 who are immunocompromised and treated with specific neutralizing antibodies via COVID-19 convalescent plasma transfusion.Data SourcesOn August 12, 2022, a systematic search was performed for clinical studies of COVID-19 convalescent plasma use in patients who are immunocompromised.Study SelectionRandomized clinical trials, matched cohort studies, and case report or series on COVID-19 convalescent plasma use in patients who are immunocompromised were included. The electronic search yielded 462 unique records, of which 199 were considered for full-text screening.Data Extraction and SynthesisThe study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were extracted by 3 independent reviewers in duplicate and pooled.Main Outcomes and MeauresThe prespecified end point was all-cause mortality after COVID-19 convalescent plasma transfusion; exploratory subgroup analyses were performed based on putative factors associated with the potential mortality benefit of convalescent plasma.ResultsThis systematic review and meta-analysis included 3 randomized clinical trials enrolling 1487 participants and 5 controlled studies. Additionally, 125 case series or reports enrolling 265 participants and 13 uncontrolled large case series enrolling 358 participants were included. Separate meta-analyses, using models both stratified and pooled by study type (ie, randomized clinical trials and matched cohort studies), demonstrated that transfusion of COVID-19 convalescent plasma was associated with a decrease in mortality compared with the control cohort for the amalgam of both randomized clinical trials and matched cohort studies (risk ratio [RR], 0.63 [95% CI, 0.50-0.79]).Conclusions and RelevanceThese findings suggest that transfusion of COVID-19 convalescent plasma is associated with mortality benefit for patients who are immunocompromised and have COVID-19.

B-cell lymphoma and lymphoproliferative diseases represent a heterogeneous and complex group of neoplasms that are accompanied by a broad range of immune regulatory disorder phenotypes. Clinical features of autoimmunity, hyperinflammation, immunodeficiency and infection can variously dominate, depending on the immune pathway most involved. Immunological imbalance can play a role in lymphomagenesis, also supporting the progression of the disease, while on the other hand, lymphoma acts on the immune system to weaken immunosurveillance and facilitate immunoevasion. Therefore, the modulation of immunity can have a profound effect on disease progression or resolution, which makes the immune system a critical target for new therapies. In the current therapeutic scenario enriched by chemo-free regimens, it is important to establish the effect of various drugs on the disease, as well as on the restoration of immune functions. In fact, treatment of B-cell lymphoma with passive immunotherapy that targets tumor cells or targets the tumor microenvironment, together with adoptive immunotherapy, is becoming more frequent. The aim of this review is to report relevant data on the evolution of the immune system during and after treatment with targeted therapy of B-cell lymphomas.

Viral clearance is likely the best way to assess the efficacy of antibody-based therapies. Although antibodies can mediate a variety of effects that include modulation of inflammation, the demonstration of viral clearance provides an accessible and measurable parameter that can be used to evaluate efficacy and determine dosing. Therefore, it is important to ascertain the ability of monoclonal antibodies and convalescent plasma to effect viral clearance. For COVID-19, which is caused by the respiratory virus SARS-CoV-2, the most common assay to assess viral clearance is via a nasopharyngeal swab (NPS). However, assessment of antibody efficacy by sampling this site may be misleading because it may not be as accessible to serum antibodies as respiratory secretions or circulating blood. Adding to the complexity of assessing the efficacy of administered antibody, particularly in randomised controlled trials (RCTs) that enroled patients at different times after the onset of COVID-19 symptoms, viral clearance may also be mediated by endogenous antibody. In this article we critically review available data on viral clearance in RCTs, matched control studies, case series and case reports of antibody therapies in an attempt to identify variables that contribute to antibody efficacy and suggest optimal strategies for future studies.
