Wang, L., He, M., Wang, W., Li, S., Zhao, G.
European journal of pediatrics. 2024
Abstract
Infliximab is a monoclonal antibody specifically binding tumor necrosis factor-alpha and has been approved for the treatment of several inflammatory disorders. However, the efficacy of infliximab in primary treatment of Kawasaki disease (KD) or retreatment of intravenous immunoglobulin (IVIG)-resistant KD in children is controversial. Therefore, we conducted a meta-analysis to compare the efficacy of infliximab alone or in combination with IVIG to IVIG. Eligible randomized and non-randomized trials were retrieved by searching literature databases prior to May 31, 2023. Pooled odds ratio (OR) and 95% confidence interval (95% CI) were calculated for dichotomous variables, and mean difference (MD) with 95% CI was estimated for continuous variables. A total of 14 eligible studies comprising 1257 participants were included. In refractory KD, infliximab alone was associated with a higher effectiveness rate (OR = 4.48, 95% CI 2.67-7.52) and defervescence rate (OR = 5.01, 95% CI 2.99-8.37) and resulted in a 1.08-day-shorter duration of fever (95% CI 0.61-1.55, P < 0.001) and 1.36-day-shorter length of hospital stay (95% CI 0.65-2.08) compared with IVIG. Incidences of coronary artery lesions (CALs), newly developing CALs, and CAL regression did not differ between both groups. For initial treatment of KD, infliximab in addition to IVIG led to a nominally significant higher effectiveness rate (OR = 2.26, 95% CI 1.02-5.01) and a larger reduction of right coronary artery Z score (MD = -0.24, 95% CI -0.27 to -0.21) but did not show additional efficacy in improving other outcomes. The safety profile was similar between both groups. Conclusion: The meta-analysis demonstrates that infliximab alone is a well-tolerated and effective treatment for IVIG-resistant KD. The additional efficacy of infliximab to IVIG for initial treatment of KD is limited. More large and high-quality trials are needed to confirm the efficacy of infliximab, especially for intensification of primary treatment for KD. What is Known: • Infliximab is a novel monoclonal antibody specifically blocking tumor necrosis factor-alpha and is approved for treatment of several immune-mediated inflammatory disorders. • The efficacy of infliximab in treating children with Kawasaki disease is controversial. What is New: • Infliximab is an effective and safe treatment for children with refractory Kawasaki disease but adds limited efficacy to intravenous immunoglobulin for initial treatment of Kawasaki disease.

Abstract
BACKGROUND Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) causes progressive or relapsing weakness and numbness of the limbs, which lasts for at least two months. Uncontrolled studies have suggested that intravenous immunoglobulin (IVIg) could help to reduce symptoms. This is an update of a review first published in 2002 and last updated in 2013. OBJECTIVES To assess the efficacy and safety of intravenous immunoglobulin in people with chronic inflammatory demyelinating polyradiculoneuropathy. SEARCH METHODS We searched the Cochrane Neuromuscular Specialised Register, CENTRAL, MEDLINE, Embase, and two trials registers on 8 March 2023. SELECTION CRITERIA We selected randomised controlled trials (RCTs) and quasi-RCTs that tested any dose of IVIg versus placebo, plasma exchange, or corticosteroids in people with definite or probable CIDP. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcome was significant improvement in disability within six weeks after the start of treatment, as determined and defined by the study authors. Our secondary outcomes were change in mean disability score within six weeks, change in muscle strength (Medical Research Council (MRC) sum score) within six weeks, change in mean disability score at 24 weeks or later, frequency of serious adverse events, and frequency of any adverse events. We used GRADE to assess the certainty of evidence for our main outcomes. MAIN RESULTS We included nine RCTs with 372 participants (235 male) from Europe, North America, South America, and Israel. There was low statistical heterogeneity between the trial results, and the overall risk of bias was low for all trials that contributed data to the analysis. Five trials (235 participants) compared IVIg with placebo, one trial (20 participants) compared IVIg with plasma exchange, two trials (72 participants) compared IVIg with prednisolone, and one trial (45 participants) compared IVIg with intravenous methylprednisolone (IVMP). We included one new trial in this update, though it contributed no data to any meta-analyses. IVIg compared with placebo increases the probability of significant improvement in disability within six weeks of the start of treatment (risk ratio (RR) 2.40, 95% confidence interval (CI) 1.72 to 3.36; number needed to treat for an additional beneficial outcome (NNTB) 4, 95% CI 3 to 5; 5 trials, 269 participants; high-certainty evidence). Since each trial used a different disability scale and definition of significant improvement, we were unable to evaluate the clinical relevance of the pooled effect. IVIg compared with placebo improves disability measured on the Rankin scale (0 to 6, lower is better) two to six weeks after the start of treatment (mean difference (MD) -0.26 points, 95% CI -0.48 to -0.05; 3 trials, 90 participants; high-certainty evidence). IVIg compared with placebo probably improves disability measured on the Inflammatory Neuropathy Cause and Treatment (INCAT) scale (1 to 10, lower is better) after 24 weeks (MD 0.80 points, 95% CI 0.23 to 1.37; 1 trial, 117 participants; moderate-certainty evidence). There is probably little or no difference between IVIg and placebo in the frequency of serious adverse events (RR 0.82, 95% CI 0.36 to 1.87; 3 trials, 315 participants; moderate-certainty evidence). The trial comparing IVIg with plasma exchange reported none of our main outcomes. IVIg compared with prednisolone probably has little or no effect on the probability of significant improvement in disability four weeks after the start of treatment (RR 0.91, 95% CI 0.50 to 1.68; 1 trial, 29 participants; moderate-certainty evidence), and little or no effect on change in mean disability measured on the Rankin scale (MD 0.21 points, 95% CI -0.19 to 0.61; 1 trial, 24 participants; moderate-certainty evidence). There is probably little or no difference between IVIg and prednisolone in the frequency of serious adverse events (RR 0.45, 95% CI 0.04 to 4.69; 1 cross-over trial, 32 participants; moderate-certainty evidence). IVIg compared with IVMP probably increases the likelihood of significant improvement in disability two weeks after starting treatment (RR 1.46, 95% CI 0.40 to 5.38; 1 trial, 45 participants; moderate-certainty evidence). IVIg compared with IVMP probably has little or no effect on change in disability measured on the Rankin scale two weeks after the start of treatment (MD 0.24 points, 95% CI -0.15 to 0.63; 1 trial, 45 participants; moderate-certainty evidence) or on change in mean disability measured with the Overall Neuropathy Limitation Scale (ONLS, 1 to 12, lower is better) 24 weeks after the start of treatment (MD 0.03 points, 95% CI -0.91 to 0.97; 1 trial, 45 participants; moderate-certainty evidence). The frequency of serious adverse events may be higher with IVIg compared with IVMP (RR 4.40, 95% CI 0.22 to 86.78; 1 trial, 45 participants, moderate-certainty evidence). AUTHORS' CONCLUSIONS Evidence from RCTs shows that IVIg improves disability for at least two to six weeks compared with placebo, with an NNTB of 4. During this period, IVIg probably has similar efficacy to oral prednisolone and IVMP. Further placebo-controlled trials are unlikely to change these conclusions. In one large trial, the benefit of IVIg compared with placebo in terms of improved disability score persisted for 24 weeks. Further research is needed to assess the long-term benefits and harms of IVIg relative to other treatments.
PICO Summary
Population
People with chronic inflammatory demyelinating polyradiculoneuropathy (9 randomised controlled trials, n= 372).
Intervention
Intravenous immunoglobulin (IVIg).
Comparison
Placebo; plasma exchange; corticosteroids (prednisolone and intravenous methylprednisolone (IVMP)).
Outcome
The primary outcome was significant improvement in disability within six weeks after the start of treatment. There was low statistical heterogeneity between the trial results, and the overall risk of bias was low for all trials that contributed data to the analysis. IVIg compared with placebo increases the probability of significant improvement in disability within six weeks of the start of treatment (risk ratio (RR) 2.40; 95% confidence interval (CI) [1.72, 3.36]; number needed to treat for an additional beneficial outcome (NNTB) 4; 95% CI [3, 5]; 5 trials, 269 participants, high-certainty evidence). The trial comparing IVIg with plasma exchange reported none of our main outcomes. IVIg compared with prednisolone probably has little or no effect on the probability of significant improvement in disability four weeks after the start of treatment (RR 0.91; 95% CI [0.50, 1.68]; 1 trial, 29 participants, moderate-certainty evidence). IVIg compared with IVMP probably increases the likelihood of significant improvement in disability two weeks after starting treatment (RR 1.46; 95% CI [0.40, 5.38]; 1 trial, 45 participants, moderate-certainty evidence).

Abstract
BACKGROUND Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a rare disease, but it is one of the most common inflammatory neuropathies in the population. It is particularly common among patients with diabetes mellitus. This raises many problems, both with the differential diagnosis of diabetic and inflammatory neuropathy, as well as the choice of treatment. Intravenous immunoglobulin (IVIG) is one of the therapeutic options. There is evidence for the effectiveness of IVIG in treating about two-thirds of patients. However, no review has been published to date systematising studies evaluating the response to IVIG treatment in patients with CIDP and coexisting diabetes. METHODS The present study is based on the PRISMA statement and is registered at PROSPERO (CRD42022356180). The study included searches of the databases of MEDLINE, ERIC, CINAHL Complete, Academic Search Ultimate and Health Source: Nursing/Academic Edition, finally including seven original papers evaluating a total of 534 patients in the review. The main inclusion criteria were the presence of a group of patients with CIDP and comorbid diabetes in the study. RESULTS The systematic review showed a lower efficacy of IVIG treatment among patients with coexisting diabetes compared with idiopathic CIDP (61 % vs 71 %). In addition, the presence of conduction blocks on neurography and shorter disease duration proved to be significant factors improving response to treatment. CONCLUSIONS Current scientific data do not allow for strong recommendations on the choice of treatment for CIDP. A randomised, multicentre study evaluating the efficacy of different therapeutic approaches to this disease entity needs to be planned.

Velusamy, Y., Vivekanandan, G., Romli, M. H., Shankar, A., Karuppiah, T., Yubbu, P.
The Turkish journal of pediatrics. 2023;65(5):719-738
Abstract
BACKGROUND To describe the existing pharmacological managements for Multisystem Inflammatory Syndrome in Children (MIS-C) in a systematic way, to identify the available pharmacological managements in MIS-C, evaluate its safety and efficacy and identify the best treatment procedures for practice recommendation. METHODS A systematic search using six databases was conducted on August 18, 2021, updated in January 26th 2023. Terminologies that were used in this search are children, MIS-C/PIMS and SARS-CoV-2. A PRISMA flow diagram was used to report the study selection process. Quality analysis was done based on NOS and GRADE tools. Data synthesis was conducted by extracting the information on drugs used, efficacy and side effects. RESULTS From the 32 articles included, a total of 2331 children with MIS-C were studied. The main pharmacological approaches were immunomodulatory therapy, i.e., intravenous immunoglobulin (IVIG) (77.3%), steroids (60.5%), and a combination of IVIG and steroids (41.3%). IVIG and steroids were found to be potentially effective and safe treatments for MIS-C. Combination of IVIG and steroids was found favorable in severe cases with higher recovery rate. Refractory treatments include second dose of initial treatment and biological response modifier drugs like anakinra, tocilizumab, infliximab. A small number of studies investigating supportive treatment consisted of vasoactive, inotropic and anticoagulation. The mortality rate was 1.28% and only three studies reported side effects from the treatment. Evidence of outcome from GRADE were mostly at moderate, low and very low levels. CONCLUSIONS This review provides preliminary evidence to support the current standard treatment practices in managing MIS-C pharmacologically. However, comprehensive investigation is required using clinical trials to provide stronger outcome evidence.

Abstract
Intravenous immunoglobulin (IVIg), which is used to treat multiple neurological conditions, may be associated with serious adverse reactions. The individual neurological disease characteristics associated with adverse reactions, along with strategies to prevent and treat adverse reactions, are uncertain. A systematic review was conducted of the databases PubMed, Embase, and Cochrane Library to summarise studies that report adverse reactions of IVIg therapy in patients with neurological disease. There were 65 studies included in the review. The reported rates of adverse reactions vary widely, but the best evidence suggests rates between 25 and 34% per patient. Common adverse reactions include headache and laboratory abnormalities. Less common but serious adverse reactions included thromboembolic complications and anaphylaxis. Overall, there is a lack of high-quality comparative data to definitively determine if any specific neurological indications are associated with a higher risk of adverse reactions. However, individual neurological disease characteristics possibly associated with an increased likelihood of adverse reactions include limited mobility (as in certain neuromuscular conditions), paraproteinaemia (as in certain peripheral neuropathies), and cardiomyopathy (as in certain myopathies). There is limited evidence to support the effectiveness of prevention and treatment strategies, which may include modification to dose, reduced infusion rate, and premedication. Further studies regarding methods to prevent and treat IVIg-ARs in neurology patients are required.

Intravenous immunoglobulins (IVIG) in severe/critical COVID-19 adult patients
Kwapisz D, Bogusławska J
Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie. 2023;163:114851
Abstract
The coronavirus disease 2019 (COVID-19) pandemic has become a huge obstacle to the health system due to the high rate of contagion. It is postulated that intravenous immunoglobulins (IVIG) can lower the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related inflammation and prevent the development of acute respiratory distress syndrome (ARDS). The main advantages of IVIG treatment might be targeting cytokine storm in severe and critical COVID-19 by influences on complement, innate immune cells, effector T-cells, and Tregs. Randomized clinical trials (RCTs) and non-RCTs evaluating the safety and efficacy of IVIG in patients with severe/critical COVID-19 were performed. It seems that early administration of high-dose IVIG (in the acceleration phase of the disease) in severe or especially critical COVID-19 may be an effective therapeutic option, but there are no strong data to use it routinely. The results regarding mortality reduction are inconclusive. Additionally, IVIG treatment carries a risk of complications that should be considered when initiating treatment. However, given the COVID-19 mortality rate and limited therapeutic options, the use of IVIG is worth considering. This review summarizes the development and highlights recent advances in treatment with IVIG of severe/critically ill COVID-19 patients.

The journal of medicine access. 2023;7:27550834231197315
Abstract
BACKGROUND Immunoglobulin replacement therapy (IgRT) benefits patients with primary immuno deficiency (PID) originating from the innate or polygenic defects in the immune system. However, evidence supporting their therapeutic role is not as explicit in secondary immuno deficiency (SID) resulting from the treatment of haematological malignancies. OBJECTIVES This study aimed to (1) create a dataset of relevant research papers, which explore the use of IgRT in SID for analysis, (2) assess the risk of bias within this dataset and (3) study the characteristics of these papers. DESIGN This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. In addition to the risk of bias, the study characteristics explored in this article included study design, study geographical location and year of publication. DATA SOURCES AND METHODS To identify studies relevant to the research question, EMBASE and PubMed databases were searched. The Population, Intervention, Comparison and Outcome (PICO) framework was used to assess study quality. Risk of bias and quality of studies were assessed in accordance with the study design. As one model was not appropriate to assess bias in all articles, several tools were used. RESULTS A total of 43 studies were identified from the literature search as relevant to the research objective. The most common study design was a retrospective case-control cohort study (n = 16/43), and randomised trials were among the least commonly used approaches (n = 1). Research in this area is occurring around the globe including the United States (n = 7), Italy (n = 7), China, India, Japan and throughout Europe. The annual number of papers in this area has varied from 2012 (n = 1) to 2021 (n = 7). The studies in this article demonstrated a varied risk of bias, with 9 of the 20 cohort studies scoring less than 5 out of 9 stars. CONCLUSIONS Randomised controlled trials are less frequently used to assess access and use of immunoglobulins. More commonly, a retrospective case-control cohort study was used which correlates with the higher risk of bias seen in the studies in this article. Most of the research concerning immunoglobulin use and access occurs in higher-income countries.

Pediatrics. 2023;152(1)
Abstract
CONTEXT Studies comparing initial therapy for multisystem inflammatory syndrome in children (MIS-C) provided conflicting results. OBJECTIVE To compare outcomes in MIS-C patients treated with intravenous immunoglobulin (IVIG), glucocorticoids, or the combination thereof. DATA SOURCES Medline, Embase, CENTRAL and WOS, from January 2020 to February 2022. STUDY SELECTION Randomized or observational comparative studies including MIS-C patients <21 years. DATA EXTRACTION Two reviewers independently selected studies and obtained individual participant data. The main outcome was cardiovascular dysfunction (CD), defined as left ventricular ejection fraction < 55% or vasopressor requirement ≥ day 2 of initial therapy, analyzed with a propensity score-matched analysis. RESULTS Of 2635 studies identified, 3 nonrandomized cohorts were included. The meta-analysis included 958 children. IVIG plus glucocorticoids group as compared with IVIG alone had improved CD (odds ratio [OR] 0.62 [0.42-0.91]). Glucocorticoids alone group as compared with IVIG alone did not have improved CD (OR 0.57 [0.31-1.05]). Glucocorticoids alone group as compared with IVIG plus glucocorticoids did not have improved CD (OR 0.67 [0.24-1.86]). Secondary analyses found better outcomes associated with IVIG plus glucocorticoids compared with glucocorticoids alone (fever ≥ day 2, need for secondary therapies) and better outcomes associated with glucocorticoids alone compared with IVIG alone (left ventricular ejection fraction < 55% ≥ day 2). LIMITATIONS Nonrandomized nature of included studies. CONCLUSIONS In a meta-analysis of MIS-C patients, IVIG plus glucocorticoids was associated with improved CD compared with IVIG alone. Glucocorticoids alone was not associated with improved CD compared with IVIG alone or IVIG plus glucocorticoids.

Frontiers in pediatrics. 2023;11:1239014
Abstract
BACKGROUND Sepsis is a major cause of mortality and morbidity globally, with around one-quarter of all sepsis-related deaths occurring in children under the age of 5. We conducted a meta-analysis and systematic review of the literature to evaluate the clinical effectiveness of an IgM-enriched immunoglobulin preparation in pediatrics patients and neonates with sepsis. METHODS Systematic searches of PubMed, the Cochrane Library and Embase databases were performed in November 2022, with no date limitations, to identify studies in which IgM-enriched immunoglobulin was used as adjunctive therapy in neonatal and pediatric patients with sepsis. RESULTS In total, 15 studies fulfilled the eligibility criteria, 13 neonatal studies and 2 pediatric studies. Pooled estimates from all studies indicated that mortality rates were significantly lower in patients who received treatment with the IgM-enriched immunoglobulin compared with controls (OR 0.41; 95% CI 0.32-0.55). Further analyses in neonatal studies, alone, showed a significant benefit with longer treatment durations (>3 days) vs. the recommended treatment duration (3 days) (OR 0.32; 95% CI 0.22-0.47) vs. (OR 0.61; 95% CI 0.41-0.92). Treatment with IgM-enriched immunoglobulin was associated with a lower mortality risk compared with controls in prospective studies vs. retrospective analyses (OR 0.37; 95% CI 0.27-0.51) vs. (OR 0.73; 95% CI 0.41-1.30). CONCLUSIONS This systematic review suggests that adjunctive treatment with IgM-enriched immunoglobulin may reduce the risk of mortality in neonatal and pediatric populations. However, large randomized controlled trials are required to further substantiate and evaluate these findings.

Current biologics in treatment of pemphigus foliaceus: a systematic review
Carver, C. A., Kalesinskas, M., Ahmed, A. R.
Frontiers in immunology. 2023;14:1267668
Abstract
BACKGROUND Pemphigus foliaceus (PF) differs from pemphigus vulgaris (PV) in that it affects only the skin and mucous membranes are not involved. Pemphigus is commonly treated with systemic corticosteroids and immunosuppressive agents (ISAs). More recently, biologics have been used. The current literature on biologic therapy often combines treatment of PF with PV, hence it is often difficult for clinicians to isolate the treatment of PF from PV. The purpose of this review was to provide information regarding the use of current biological therapy, specifically in PF. MATERIALS AND METHODS A search of PubMed, Embase, and other databases was conducted using keywords pemphigus foliaceus (PF), rituximab (RTX), intravenous immunoglobulin (IVIg), and biologics. Forty-one studies were included in this review, which produced 105 patients with PF, treated with RTX, IVIg, or a combination of both. Eighty-five patients were treated with RTX, eight patients with IVIg, and 12 received both RTX and IVIg. RESULTS Most patients in this review had PF that was nonresponsive to conventional immunosuppressive therapies (CIST), and had significant side effects from their use. RTX treatment resulted in complete remission (CR) in 63.2%, a relapse rate of 39.5%, an infection rate of 19.7%, and a mortality rate of 3.9%. Relapse was greater in the lymphoma (LP) protocol than the rheumatoid arthritis (RA) protocol (p<0.0001). IVIg led to CR in 62.5% of patients, with no relapses or infections. Patients receiving both biologics experienced better outcomes when RTX was first administered, then followed by IVIg. Follow-up durations for patients receiving RTX, IVIg, and both were 22.1, 24.8, and 35.7 months, respectively. DISCUSSION In pemphigus foliaceus patients nonresponsive to conventional immunosuppressive therapy or in those with significant side effects from CIST, RTX and IVIg appear to be useful agents. Profile of clinical response, as well as relapse, infection, and mortality rates in PF patients treated with RTX were similar to those observed in PV patients. The data suggests that protocols specific for PF may produce better outcomes, less adverse effects, and improved quality of life.
