Wang Z, Zhao S, Tang Y, Wang Z, Shi Q, Dang X, Gan L, Peng S, Li W, Zhou Q, et al
European journal of pediatrics. 2022;:1-12
Abstract
The purpose of this systematic review is to evaluate the efficacy and safety of using potential drugs: remdesivir and glucocorticoid in treating children and adolescents with COVID-19 and intravenous immunoglobulin (IVIG) in treating MIS-C. We searched seven databases, three preprint platform, ClinicalTrials.gov, and Google from December 1, 2019, to August 5, 2021, to collect evidence of remdesivir, glucocorticoid, and IVIG which were used in children and adolescents with COVID-19 or MIS-C. A total of nine cohort studies and one case series study were included in this systematic review. In terms of remdesivir, the meta-analysis of single-arm cohort studies have shown that after the treatment, 54.7% (95%CI, 10.3 to 99.1%) experienced adverse events, 5.6% (95%CI, 1.2 to 10.1%) died, and 27.0% (95%CI, 0 to 73.0%) needed extracorporeal membrane oxygenation or invasive mechanical ventilation. As for glucocorticoids, the results of the meta-analysis showed that the fixed-effect summary odds ratio for the association with mortality was 2.79 (95%CI, 0.13 to 60.87), and the mechanical ventilation rate was 3.12 (95%CI, 0.80 to 12.08) for glucocorticoids compared with the control group. In terms of IVIG, most of the included cohort studies showed that for MIS-C patients with more severe clinical symptoms, IVIG combined with methylprednisolone could achieve better clinical efficacy than IVIG alone.Conclusions: Overall, the current evidence in the included studies is insignificant and of low quality. It is recommended to conduct high-quality randomized controlled trials of remdesivir, glucocorticoids, and IVIG in children and adolescents with COVID-19 or MIS-C to provide substantial evidence for the development of guidelines. What is Known: • The efficacy and safety of using potential drugs such as remdesivir, glucocorticoid, and intravenous immunoglobulin (IVIG) in treating children and adolescents with COVID-19/MIS-C are unclear. What is New: • Overall, the current evidence cannot adequately demonstrate the effectiveness and safety of using remdesivir, glucocorticoids, and IVIG in treating children and adolescents with COVID-19 or MIS-C. • We are calling for the publication of high-quality clinical trials and provide substantial evidence for the development of guidelines.

Abstract
The aim of our study was to compare the efficacy of two dosages of hepatitis B immunoglobulin (HBIG) combined with HBV vaccine (HBVac) to prevent mother-to-child transmission (MTCT) of hepatitis B in HBsAg- and HBeAg-positive mother. We enrolled 331 mother-infant pairs with HBsAg- and HBeAg-positive maternal state from the Women's Hospital School of Medicine of Zhejiang University. Newborns were randomly distributed into two groups according to the dosages of HBIG injection: 100 IU and 200 IU. Newborns from both groups were injected with HBVac in the same doses. We compared the immune outcomes between the two groups and explore the influencing factors of immune outcomes through regression analysis. There was no statistically significant relationship between HBsAg serological transmission of newborns and dosages of HBIG in HBsAg- and HBeAg-positive mother (p > .05). The Logistic regression showed that high DNA load is a risk factor for passive-active immunoprophylaxis failure for both 100 IU and 200 IU group, but higher-dosage HBIG is not necessary for higher-viral-load pregnant women with HBsAg- and HBeAg-positive. In conclusion, combined application of HBVac and a single dose of 100 IU HBIG can achieve the ideal MTCT interruption results for HBsAg- and HBeAg-positive pregnant women.IMPACT STATEMENTWhat is already known on this subject? Passive-active immunoprophylaxis is proved to be effective in preventing mother-to-child transmission of hepatitis B. Hepatitis B vaccine combined with 100 IU or 200 IU immunoglobulin is mostly recommended in China.What do the results of this study add? At present, there is still a lack scientific basis for improving existing strategies and measures to prevent mother-to-child transmission of hepatitis B in China.What are the implications of these findings for clinical practice and/or further research? 100 IU and 200 IU immunoglobulin show equivalent blocking effect, and combined use of hepatitis B vaccine and 100 IU immunoglobulin is more cost-effective.

Zhang J, Yang Y, Yang N, Ma Y, Zhou Q, Li W, Wang X, Huang L, Luo X, Fukuoka T, et al
Annals of Translational Medicine. 2020
Abstract
Background: Intravenous immunoglobulin (IVIG) is usually used as supportive therapy, but the treatment of COVID-19 by IVIG is controversial This rapid review aims to explore the clinical effectiveness and safety of IVIG in the treatment of children with severe COVID-19 Methods: We systematically searched the literature on the use of IVIG in patients with COVID-19, severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS), including both adults and children We assessed the risk of bias and quality of evidence and reported the main findings descriptively Results: A total of 1,519 articles were identified by initial literature search, and finally six studies met our inclusion criteria, included one randomized controlled trial (RCT), four case series and one case report involving 198 patients One case series showed the survival of COVID-19 patients with acute respiratory distress syndrome (ARDS) was not improved by IVIG One case report showed high-dose IVIG could improve the outcome of COVID-19 adults Three observational studies showed inconsistent results of the effect of IVIG on SARS patients One RCT showed that IVIG did not reduce mortality or the incidence of nosocomial infection in adults with severe SARS The quality of evidence was between low and very low Conclusions: The existing evidence is insufficient to support the efficacy or safety of IVIG in the treatment of COVID-19

Effect of Early Intravenous Immunoglobulin Therapy in Kawasaki Disease: A Systematic Review and Meta-Analysis
Yan F, Zhang H, Xiong R, Cheng X, Chen Y, Zhang F
Frontiers in pediatrics. 2020;8:593435
Abstract
Background: In the latest 2017 American Heart Association guidelines for Kawasaki disease (KD), there are no recommendations regarding the early administration of intravenous immunoglobulin (IVIG). Therefore, the purpose of this systematic review and meta-analysis was to investigate the effects of early IVIG therapy on KD. Methods: We searched databases including the PubMed, Medline, the Cochrane Library, and the Clinicaltrials.gov website until July 2019. Results: Fourteen studies involving a total of 70,396 patients were included. Early treatment with IVIG can lead to an increased risk of IVIG unresponsiveness [OR 2.24; 95% CI (1.76, 2.84); P = 0.000]. In contrast to the studies performed in Japan [OR 1.27; 95% CI (0.98, 1.64); P = 0.074] that found no significant difference in coronary artery lesions (CAL) development, studies conducted in China [OR 0.73; 95% CI (0.66, 0.80); P = 0.000] and the United States [OR 0.50; 95% CI (0.38, 0.66); P = 0.000] showed a reduced risk in the occurrence of CAL with early IVIG treatment. Conclusions: At present, the evidence does not support the treatment with IVIG in the early stage of the onset of KD. But, early IVIG treatment could be a protective factor against the development of CAL, which needs to be further clarified.

European Journal of Pediatrics. 2018;177((8):):1279-1292
Abstract
The purpose of this study was to identify the clinical features and laboratory factors that are predictive of intravenous immunoglobulin (IVIG)-resistant Kawasaki disease. Multiple databases were searched for relevant studies on IVIG-resistant Kawasaki disease published from January 2002 to April 2017. Eligible studies were retrieved by manual review of the references. Stata 12 was used for the meta-analysis. Weighted mean differences and odds ratios with 95% confidence intervals were calculated for several indices. Twenty-eight studies involving 26,260 patients comprising 4442 IVIG-resistant Kawasaki disease patients and 21,818 IVIG-sensitive Kawasaki disease patients were included. The meta-analysis showed that the erythrocyte sedimentation rate (ESR) in the IVIG-resistant group was significantly higher than that in the IVIG-sensitive group, and that platelet count and hemoglobin levels were significantly lower in the IVIG-resistant group. The patients with oral mucosa alterations, cervical lymphadenopathy, swelling of the extremities, polymorphous rash, and initial administration of IVIG ≤ 4.0 days after the onset of symptoms were more likely to be IVIG resistant. CONCLUSION The initial administration of IVIG ≤ 4.0 days after the onset of symptoms increased ESR and decreased hemoglobin and platelet counts, oral mucosa alterations, cervical lymphadenopathy, swelling of the extremities, and polymorphous rash and are the risk factors for IVIG-resistant Kawasaki disease. What is Known: * Recent reports on this topic are about aspartate aminotransferase (AST), alanine aminotransferase (ALT), gammaglutamyl transferase, total bilirubin, white blood cells, platelets, erythrocyte sedimentation rate (ESR), polymorphonuclear leukocytes (PMN), C-reactive protein (CRP), pro-brain natriuretic peptide (BNP), albumin, and sodium as the risk factors in the IVIG-resistant Kawasaki disease; however, no studies have been published on clinical features as predictors of IVIG resistance. What is New: * This meta-analysis identified the clinical features, the initial administration of IVIG ≤ 4.0 days after the onset of symptoms, and much more comprehensive laboratory indicators, such as hemoglobin, as predictors of IVIG-resistant Kawasaki disease.

Li J, Chen Y, Liu C, Hu Y, Li L
American Journal of Reproductive Immunology. 2013;70((6):):434-47.
Abstract
Intravenous immunoglobulin (IVIG) has been introduced empirically into IVF/ICSI programs with the hopes of improving in vitro fertilization (IVF) success. However, the effects of IVIG have been inconsistent. We investigated the effects of IVIG on hard outcomes, including implantation rate, clinical pregnancy rate, live birth rate, miscarriage rate, and live birth rate per embryo transferred. The PubMed, EMBASE, and CNKI databases were searched up to June of 2013 and 10 studies were included. Case-controlled studies comparing IVIG with placebo in IVF/ICSI women and/or unexplained infertility were included. Using fixed and random effects models, the pooled risk ratios (RR) with 95% confidence intervals (CIs) were calculated. The use of IVIG was significantly associated with a higher implantation rate and RR was 2.708 (95%CI: 1.302-5.629) compared with the placebo. The clinical pregnancy rate and the live birth rate were significantly increased in patients randomized to IVIG; RR was 1.475 (95%CI: 1.191-1.825) for the clinical pregnancy rate and RR was 1.616 (95%CI: 1.243-2.101) for the live birth rate. Moreover, the miscarriage rate was significantly less in patients randomized to IVIG (0.352, 95%CI: 0.168-0.738), but the live birthrate per embryo transferred was not (2.893; 95%CI: 0.810-10.331) less. Our results strongly support that IVIG is a useful treatment option for women undergoing repeated IVF failure. 2013 John Wiley & Sons Ltd.
