Abstract
This study presents a novel approach toward the one-pot green synthesis of ZIF-8/IgG composite, focusing on its precise orientation and protection of the anti-aflatoxins antibody. The antibody orientation is achieved through the specific binding of IgG to the Fc region of the antibody, while the antibody protection is accomplished by the structural change restriction of ZIF-8 framework to the antibody. Consequently, the antibody exhibits enhanced target capability and significantly improved tolerance to organic solvents. The ZIF-8/IgG/anti-AFT was employed for the purification and detection of AFTs by coupling with UPLC. Under optimized conditions, the recoveries of spiked AFTs in peanut oils are between 86.1% and 106.4%, with relative standard deviations (RSDs) ranging from 0.8% to 8.8%. The linearity range is 0.5-20.0 ng for AFB1 and AFG1, 0.125-5.0 ng for AFB2 and AFG2, the limit of detection is 0.1 ng for AFB1 and AFG1, 0.03 ng for AFB2 and AFG2.

Abstract
BACKGROUND Sensitized lung transplant recipients are at increased risk of developing donor-specific antibodies, which have been associated with acute and chronic rejection. Perioperative intravenous immune globulin has been used in sensitized individuals to down-regulate antibody production. METHODS We compared patients with a pre-transplant calculated panel reactive antibody ≥25% who did not receive preemptive immune globulin therapy to a historical control that received preemptive immune globulin therapy. Our cohort included 59 patients, 17 patients did not receive immune globulin therapy and 42 patients received therapy. RESULTS Donor specific antibody development was numerically higher in the non-immune globulin group compared to the immune globulin group (58.8% vs 33.3%, respectively, odds ratio 2.80, 95% confidence interval [0.77, 10.79], p = 0.13). Median time to antibody development was 9 days (Q1, Q3: 7, 19) and 28 days (Q1, Q3: 7, 58) in the non-immune globulin and immune globulin groups, respectively. There was no significant difference between groups in the incidence of primary graft dysfunction at 72 h post-transplant or acute cellular rejection, antibody-mediated rejection, and chronic lung allograft dysfunction at 12 months. CONCLUSION These findings are hypothesis generating and emphasize the need for larger, randomized studies to determine association of immune globulin therapy with clinical outcomes.

Abstract
BACKGROUND Monoclonal antibody (palivizumab), intravenous immune globulin (IGIV), or respiratory syncytial virus (RSV)-polyclonal-hyperimmune-globulin (RSV-IG as Respigam®, RI-001, RI-002) are used with ribavirin in RSV-infected immunocompromised patients, with debated efficacy. Palivizumab-resistance (PR) can arise during treatment of persistent infections in this population. RSV-IG may confer benefit in PR-RSV infection. METHODS RSV-IG [RI-001] was provided for an immunocompromised infant with RSV-pneumonitis refractory to ribavirin and palivizumab. RSV-neutralizing antibody, respiratory RSV load (qPCR), and F-gene-sequence-detection of PR was determined. Prophylactic RSV-IG [RI-002] or palivizumab was administered in a cotton-rat model infected with wild-type and PR-RSV. Lung RSV load and neutralizing antibody were measured. RESULTS As protective RI-001-neutralizing antibody titers waned in the infant, a subpopulation of PR-escape mutants were detected with a fatal RSV-burden in the lungs. In PR-RSV-infected cotton rats, prophylactic RI-002 reduced RSV-load in the lungs (2.45 vs 0.28 log10 PFU/g lung-tissue reduction, respectively, p < 0.05) and provided protective RSV-neutralizing antibody. CONCLUSIONS RSV-IG and ribavirin use in immunocompromised patients requires further study.

Abstract
BACKGROUND The pathogenesis of PD has not been fully elucidated, but recent studies have shown that the adaptive immune system may play a role in the pathology of PD. However, there is a lack of longitudinal studies exploring the relationship between peripheral adaptive immune indicators and the rate of disease progression in PD. METHODS We included early PD patients with disease duration < 3 years and assessed the severity of clinical symptoms and peripheral adaptive immune system indicators (CD3+, CD4+, CD8+ T lymphocyte subsets, CD4+:CD8+ ratio, IgG, IgM, IgA, C3, C4) at baseline. Clinical symptoms were followed up every year. We used the Unified Parkinson's Disease Rating Scale (UPDRS) to assess the disease severity and the Montreal Cognitive Assessment (MoCA) to assess global cognitive function. RESULT A total of 152 PD patients were eventually included. The linear mixed model showed no significant association between baseline peripheral blood adaptive immune indicators and baseline MoCA scores or UPDRS part III scores. A higher baseline CD3+ lymphocyte percentage was associated with a slower rate of decline in MoCA scores. Baseline immune indicators were not associated with the rate of change of the UPDRS part III scores. CONCLUSION The subset of peripheral T lymphocytes was related to the rate of cognitive decline in early PD patients, suggesting that the peripheral adaptive immune system may be involved in the process of cognitive decline in early PD.

Abstract
Background Anti-thymoglobulin (ATG)-based immunosuppressive treatment (IST) is the standard first-line management for patients with severe AA/very severe AA (SAA/VSAA) and is not suitable for allogeneic stem cell transplantation. The response predictor was not fully investigated. Objective The present study attempted to explore other characteristics, such as serum lipid changes, during ATG-based IST and analyzed their significance in predicting IST response and survival. Methods A total of 61 newly diagnosed SAA/VSAA patients who received ATG-based IST were enrolled from January 2011 to June 2019. The blood lipid levels, immunoglobulins, and peripheral T lymphocytes were retrospectively collected, and their correlations with IST response, estimated 8.5-year overall survival (OS) and event-free survival (EFS) were analyzed. Results The overall response (OR)/complete remission (CR) at 3, 6, and 9 months was 24.6%/6.6%, 52.5%/14.8%, and 65.6%/23.0%, respectively. Based on the 9-month response effect, patients were divided into IST-response (IST-R) and IST-nonresponse (IST-NR) groups. The subgroup baseline characteristics showed that the disease severity grade, absolute neutrophil granulocyte count (ANC), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and apolipoprotein-A (Apo-A) differed between the IST-R and IST-NR groups. Patients with lower Apo-A (< 1.205 g/L) level pretreatment had a better event-free survival (EFS), and a moderate negative correlation was established between the pretreatment Apo-A and 9-month response (P = 0.004). In addition, the T-cell subset and immunoglobulin analyses showed that the responsive patients had a low serum IgA level, which decreased further after therapy. Additionally, a moderate negative correlation was established between the 3-month IgA and 9-month response (P = 0.006). Conclusion Serum Apo-A is a prognostic biomarker for newly diagnosed < 60-year-old SAA/VSAA patients who received ATG-based IST (registered at chictr.org.cn as # ChiCTR2100052979).

Abstract
BACKGROUND To study the association between indoor environment (MiE), blood trace elements (BTE), and immune globulin (PRO) among workers from vegetables plastic greenhouse, and to assess the mediate effects on MiE and PRO by BTE. METHODS Overall, 168 practitioner and corresponding sheds were included from cross-sectional study in 2016. BTE and PRO were determined by physical test and MiE data from field and laboratory measurement. The association was assessed using canonical correlation analysis. The direct and indirect effects between MiE, PRO and BTE were conducted by structural equation model. 5000 times bootstrap methods were performed to estimate coefficient and 95% confidence interval. RESULTS MiE was moderately correlated with BTE (canonical coefficient = 0.439), and BTE was strongly correlated with PRO (canonical coefficient = 0.514 and 0.481). No statistical evidence was found for the overall impact of MiE on PRO, and BTE as an intermediary affecting its relevance was not confirmed. Only the path way of the BTE impact on PRO had a significant positive effect (P=0.012). CONCLUSION BTE was positively associated with PRO, therefore, reducing exposure in greenhouse is a pathway to remain blood trace elements, and further effect the immune protein in human body.

Abstract
INTRODUCTION Despite many recent advances in the treatment of multiple myeloma (MM), infection remains a major cause of morbidity and mortality. Prior studies have shown mixed results using intravenous immunoglobulin (IVIG) to prevent infections in MM and were conducted prior to most modern MM therapies. PATIENTS AND METHODS We retrospectively reviewed all patients with MM treated with IVIG at our institution from 2010 to 2017. The primary endpoint was the incidence rate ratio (IRR) of infectious events (IEs) per patient-year during IVIG versus observation. RESULTS A total of 68 patients were included; 151 IEs occurred during 918 months of IVIG treatment, whereas 446 IEs occurred during 2484 months of observation. Although the annual rate of IEs was substantially higher during periods of progressive disease (PD) compared with non-PD (4.9 vs. 1.8; P < .001), most IEs occurred during periods of non-PD (75% vs. 25% during PD). There was no overall difference in the annual rate of IEs per patient between IVIG and observation (1.97 vs. 2.16; IRR, 0.92; 95% confidence interval [CI], 0.76-1.10; P = .376). The subgroup of patients with hypogammaglobulinemia and whose myeloma was in a non-PD phase had a significant reduction in all-grade IEs (1.20 vs. 1.92; IRR, 0.63; 95% CI, 0.45-0.88; P = .009) and ≥ grade 3 IEs (0.25 vs. 0.56; IRR, 0.45; 95% CI, 0.22-0.94; P = .041) with IVIG compared with observation. CONCLUSION Although treatment with IVIG did not show benefit in the overall population, there may be subgroups of patients that derive significant benefit. Additional observational studies are needed to confirm these findings and further refine patient selection.

The COVID-19 pandemic, caused by SARS-CoV-2, has led to a rapid search for therapeutic and preventive measures because of the potentially severe course of infection. The antiviral drug, remdesivir, and the anti-inflammatory agent, dexamethasone, have shown beneficial effects. As the current COVID-19 vaccines are not yet fully available to everyone, or they may not be readily and universally accepted, various treatment options are being evaluated and will still be needed under these conditions. One of these treatment options, passive immunization, has shown promise in some studies. Further research is needed to determine the utility of immunotherapy with convalescent plasma or artificially produced monoclonal antibodies for the treatment of symptomatic patients, and potentially for use as post-exposure prophylaxis, at least until more effective drugs are available or safe and effective vaccines are distributed and administered to everyone.

Abstract
Background Pregnant women are at increased risk of thrombotic adverse events. Plasma derived immune globulin (IG) products, which are used in pregnancy for various indications, may contain procoagulant impurity activated coagulation factor XI (FXIa). Procoagulant IG products have been associated with increased thrombogenicity but their effect in pregnancy is unknown. Methods Late pregnant (gestation days 17–20) or early lactation (days 1–3) and control female mice were treated with IGs supplemented with human FXIa then subjected to ferric chloride (FeCl3) vessel injury. Occlusion of blood vessel was assessed by recording blood velocity in the femoral vein for 20 min using doppler ultrasound laser imaging. FXIa dose was selected by the ability to increase thrombin generation in mouse plasma in vitro. Results FXIa produced robust thrombin generation in mouse plasma ex vivo. Following FeCl3 injury, pregnant and non-pregnant mice receiving IG + FXIa exhibited faster reduction of blood velocity in femoral vein compared to IG alone or untreated controls. In vitro, thrombin generation in plasma samples collected after thrombosis in FXIa-treated animals was elevated and could be reduced by anti-FXI antibody. Conclusions Our results suggest that intravenously-administered FXIa may contribute to thrombosis at the site of vascular injury in both pregnant and non-pregnant animals.

Abstract
Sickle Cell Disease (SCD) is a chronic hemolytic disorder associated with frequent pain episodes, end organ damage and a shortened lifespan. Currently there exist no disease specific targeted therapies for the treatment of acute vaso-occlusive crisis (VOC) and management with analgesics and hydration is purely supportive. Improvement in understanding of disease pathophysiology has resulted in a great interest in disease modifying novel therapies and many are being evaluated in clinical trials. Here we report the results from the pre-specified mid-point analysis of the Phase 2 study of Intravenous Gamma Globulin (IVIG) for the treatment of acute VOC in patients with SCD and lessons learned.

Abstract
While active immunization elicits a lasting immune response by the body, passive immunotherapy transiently equips the body with exogenously generated immunological effectors in the form of either target-specific antibodies or lymphocytes functionalized with target-specific receptors. In either case, administration or expression of recombinant proteins plays a fundamental role. mRNA prepared by in vitro transcription (IVT) is increasingly appreciated as a drug substance for delivery of recombinant proteins. With its biological role as transient carrier of genetic information translated into protein in the cytoplasm, therapeutic application of mRNA combines several advantages. For example, compared to transfected DNA, mRNA harbors inherent safety features. It is not associated with the risk of inducing genomic changes and potential adverse effects are only temporary due to its transient nature. Compared to the administration of recombinant proteins produced in bioreactors, mRNA allows supplying proteins that are difficult to manufacture and offers extended pharmacokinetics for short-lived proteins. Based on great progress in understanding and manipulating mRNA properties, efficacy data in various models have now demonstrated that IVT mRNA constitutes a potent and flexible platform technology. Starting with an introduction into passive immunotherapy, this review summarizes the current status of IVT mRNA technology and its application to such immunological interventions.

Abstract
Congenital infection as well as infection of immunocompromised individuals by cytomegalovirus (CMV) can be associated with significant morbidity, mortality, and long-term adverse health outcomes. Assessment of anti-viral activity using appropriate assays is essential for ensuring safe and efficacious use of therapeutic CMV immune globulin (IG) products. In this study, we used commercial ELISA kits to compare anti-CMV antibody binding activity and avidity for lots of CMV-specific and normal IG products available in the US market. Additionally, neutralizing activity of IG products was measured against CMV strains (AD169wt131 or TB40E-GFP) in MRC-5 human fibroblasts and ARPE-19 human epithelial cells. Our data revealed that, regardless of the method, anti-CMV activity was higher in CMV IG lots we tested compared with normal IG lots; CMV binding activity was at least 4-fold higher, and neutralizing activity at least 2- and 3-fold higher for epithelial and fibroblast cells, respectively, in CMV IG lots compared with normal IG lots. Furthermore, anti-CMV activity values from all three methods (ELISA, neutralization in MRC-5 cells, and neutralization in ARPE-19 cells) were highly correlated, whereas avidity, although higher in CMV IG lots, did not correlate well with either binding or neutralizing activities.

Abstract
Human immunoglobulin preparations for intravenous or subcutaneous administration are the cornerstone of treatment in patients with primary immunodeficiency diseases affecting the humoral immune system. Intravenous preparations have a number of important uses in the treatment of other diseases in humans as well, some for which acceptable treatment alternatives do not exist. We provide an update of the evidence-based guideline on immunoglobulin therapy, last published in 2006. Given the potential risks and inherent scarcity of human immunoglobulin, careful consideration of its indications and administration is warranted.

Abstract
PURPOSE There is currently little evidence to support intravenous immune globulin (IVIG) therapy for pediatric myocarditis. The purpose of our retrospective study was to assess the effects of IVIG therapy in patients with presumed myocarditis on survival and recovery of ventricular function and to determine the factors associated with its poor outcome. METHODS We reviewed all consecutive cases of patients with myocarditis with left ventricular dysfunction verified by echocardiogram who had visited 3 university hospitals between January 2000 and September 2009. These patients were divided into 2 groups. Group 1 consisted of 23 patients (69.6%) who received IVIG alone or IVIG in combination with steroids, and group 2 consisted of 10 patients (30.3%) who received neither IVIG nor other immunosuppressive agents. Clinical manifestations, laboratory results, echocardiographic findings, and outcomes were compared between these 2 groups. RESULTS One year after the initial presentation, the difference in the probability of survival did not show statistical significance in IVIG-treated patients (P=0.607). Of the echocardiographic parameters on admission, a shortening fraction of less than 15% was associated with unremitting cardiac failure. Furthermore, anemic patients were more likely to have elevated N-terminal fragment levels of the B-type natriuretic peptide (NT-proBNP) in the progressed group (P=0.036). CONCLUSION There was no difference between the IVIG-treated patients and the control patients in the degree of recovery of left ventricular function and survival. Prospective, randomized, clinical studies are needed to elucidate the effects of IVIG treatment during the acute stage of myocarditis on ultimate outcomes.
