Abstract
BACKGROUND Previous findings from the Swissped RECOVERY trial showed that patients with Pediatric Inflammatory Multisystem Syndrome-Temporally Associated with SARS-CoV-2 (PIMS-TS) who were randomly assigned to intravenous immunoglobulins or methylprednisolone have a comparable length of hospital stay. Here, we report the 6-month follow-up outcomes of cardiac pathologies and normalisation of clinical or laboratory signs of inflammation from this study population. METHODS This pre-planned follow-up of patients with PIMS-TS included the Swissped RECOVERY Trial reports on the 6-month outcomes of the cohort after randomisation, with a focus on cardiac, haematological, and biochemical findings. The trial was an investigator-initiated randomised multicentre open-label two-arm trial in children and adolescents hospitalised with PIMS-TS at ten hospitals in Switzerland. Cardiological assessments and laboratory analyses were prospectively collected in the intention-to-treat analysis on pre-defined intervals after hospital discharge. Differences between randomised arms were investigated using Chi-square test for categorical and Wilcoxon test for continuous variables. The trial is registered with the Swiss National Clinical Trials Portal (SNCTP000004720) and ClinicalTrials.gov (NCT04826588). FINDINGS Between May 21, 2021 and April 15, 2022, 75 patients with a median age of 9.1 years (IQR 6.2-12.2) were included in the intention-to-treat population (37 in the methylprednisolone group and 38 in the intravenous immunoglobulin group). During follow-up, the incidence of abnormal left ventricular systolic function, coronary artery aneurysms (CAA), and other signs of inflammation were comparable in both groups. However, we detected cardiac abnormalities with low incidence and a mild degree grade of pathology. CAAs were observed in 2/38 children (5.3%) in the IVIG group and 1/37 children (2.7%) in the methylprednisolone group at 6-month follow-up (difference proportion 0.75; 95% confidence interval (CI) -0.05 to 1.0; p = 0.39). INTERPRETATION Methylprednisolone alone may be an acceptable first-line treatment as left ventricular systolic dysfunction and clinical/laboratory evidence for inflammation quickly resolved in all children. However, our findings need further confirmation through larger studies as our sample size is likely to be of insufficient power to address rare clinically relevant adverse outcomes.

Immunomodulatory therapy in children with paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS, MIS-C; RECOVERY): a randomised, controlled, open-label, platform trial
The Lancet. Child & adolescent health. 2024
Abstract
BACKGROUND Paediatric multisystem inflammatory syndrome temporally associated with SARS-CoV-2 (PIMS-TS), also known as multisystem inflammatory syndrome in children (MIS-C) emerged in April, 2020. The paediatric comparisons within the RECOVERY trial aimed to assess the effect of intravenous immunoglobulin or corticosteroids compared with usual care on duration of hospital stay for children with PIMS-TS and to compare tocilizumab (anti-IL-6 receptor monoclonal antibody) or anakinra (anti-IL-1 receptor antagonist) with usual care for those with inflammation refractory to initial treatment. METHODS We did this randomised, controlled, open-label, platform trial in 51 hospitals in the UK. Eligible patients were younger than 18 years and had been admitted to hospital for PIMS-TS. In the first randomisation, patients were randomly assigned (1:1:1) to usual care (no additional treatments), usual care plus methylprednisolone (10mg/kg per day for 3 consecutive days), or usual care plus intravenous immunoglobulin (a single dose of 2 g/kg). If further anti-inflammatory treatment was considered necessary, children aged at least 1 year could be considered for a second randomisation, in which patients were randomly assigned (1:2:2) to usual care, intravenous tocilizumab (12 mg/kg in patients <30 kg; 8mg/kg in patients ≥30 kg, up to a maximum dose of 800 mg), or subcutaneous anakinra (2 mg/kg once per day in patients ≥10 kg). Randomisation was by use of a web-based simple (unstratified) randomisation with allocation concealment. The primary outcome was duration of hospital stay. Analysis was by intention to treat. For treatments assessed in each randomisation, a single Bayesian framework assuming uninformative priors for treatment was used to jointly assess the efficacy of each intervention compared with usual care. The trial was registered with ISRCTN (50189673) and ClinicalTrials.gov (NCT04381936). FINDINGS Between May 18, 2020, and Jan 20, 2022, 237 children with PIMS-TS were enrolled and included in the intention-to-treat analysis. Of the 214 patients who entered the first randomisation, 73 were assigned to receive intravenous immunoglobulin, 61 methylprednisolone, and 80 usual care. Of the 70 children who entered the second randomisation (including 23 who did not enter the first randomisation), 28 were assigned to receive tocilizumab, 14 anakinra, and 28 usual care. Mean age was 9·5 years (SD 3·8) in the randomisation and 9·6 years (3·6) in the second randomisation. 118 (55%) of 214 patients in the first randomisation and 39 (56%) of 70 patients in the second randomisation were male. 130 (55%) of 237 patients were Black, Asian, or minority ethnic, and 105 (44%) were White. Mean duration of hospital stay was 7·4 days (SD 0·4) in children assigned to intravenous immunoglobulin and 7·6 days (0·4) in children assigned to usual care (difference -0·1 days, 95% credible interval [CrI] -1·3 to 1·0; posterior probability 59%). Mean duration of hospital stay was 6·9 days (SD 0·5) in children assigned to methylprednisolone (difference from usual care -0·7 days, 95% CrI -1·9 to 0·6; posterior probability 87%). Mean duration of hospital stay was 6·6 days (SD 0·7) in children assigned to second-line tocilizumab and 9·9 days (0·9) in children assigned to usual care (difference -3·3 days, 95% CrI -5·6 to -1·0; posterior probability >99%). Mean duration of hospital stay was 8·5 days (SD 1·2) in children assigned to anakinra (difference from usual care -1·4 days, 95% CrI -4·3 to 1·8; posterior probability 84%). Two persistent coronary artery aneurysms were reported among patients assigned to usual care in the first randomisation. There were few cardiac arrythmias, bleeding, or thrombotic events in any group. Two children died; neither was considered related to study treatment. INTERPRETATION Moderate evidence suggests that, compared with usual care, first-line intravenous methylprednisolone reduces duration of hospital stay for children with PIMS-TS. Good evidence suggests that second-line tocilizumab reduces duration of hospital stay for children with inflammation refractory to initial treatment. Neither intravenous immunoglobulin nor anakinra had any effect on duration of hospital stay compared with usual care. FUNDING Medical Research Council and National Institute of Health Research.

Journal of plastic, reconstructive & aesthetic surgery : JPRAS. 2024;90:305-314
Abstract
BACKGROUND NA OBJECTIVE Evaluate the safety and feasibility of platelet-rich plasma (PRP) in the treatment of giant congenital melanocytic nevi (GCMN) in children with human acellular dermal matrix (HADM) transplantation. PATIENTS AND METHODS A total of 22 children with GCMN were included in the study. They were divided into an experimental and a control group. The experimental group used the method of HADM with Razor Autologous Skin Graft combined with PRP to repair skin and soft tissue defects after giant nevus resection (Group A, n = 11). The control group was treated with HADM with Razor Autologous Skin Graft (Group B, n = 11) only. To compare the survival rate of skin grafts, we used the Vancouver Scar Scale (VSS) for the postoperative skin graft area and the Patient and Observer Scar Assessment Scale (POSAS) to compare the two groups of patients. RESULTS There was no statistically significant difference in age, gender, location of giant nevi, and pathological classification between Group A and Group (P > 0.05). The survival rate of skin grafting and the VSS and POSAS scores of scar tissue in group A were superior to those of group B (P < 0.05). CONCLUSIONS PRP has improved the survival rate of composite skin grafting in children with GCMN, and long-term satisfactory prognosis of scar healing. Therefore, we consider this treatment method a valuable contribution to clinical practice.

Abstract
BACKGROUND The emergence of paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) led to the widespread use of anti-inflammatory treatments in the absence of evidence from randomised controlled trials (RCTs). We aimed to assess the effectiveness of intravenous methylprednisolone compared with intravenous immunoglobulins. METHODS This is an open-label, multicentre, two-arm RCT done at ten hospitals in Switzerland in children younger than 18 years hospitalised with PIMS-TS (defined as age <18 years; fever and biochemical evidence of inflammation, and single or multiorgan dysfunction; microbiologically proven or putative contact with SARS-CoV-2; and exclusion of any other probable disease). Patients were randomly assigned 1:1 to intravenous methylprednisolone (10 mg/kg per day for 3 days) or intravenous immunoglobulins (2 g/kg as a single dose). The primary outcome was length of hospital stay censored at day 28, death, or discharge. Secondary outcomes included proportion and duration of organ support. Analyses were done by intention-to-treat. The study was registered with Swiss National Clinical Trials Portal (SNCTP000004720) and ClinicalTrials.gov (NCT04826588). FINDINGS Between May 21, 2021, and April 15, 2022, 75 patients with a median age of 9·1 years (IQR 6·2-12·2) were included in the intention-to-treat population (37 in the methylprednisolone group and 38 in the intravenous immunoglobulins group). The median length of hospital stay was 6·0 days (IQR 4·0-8·0) in the methylprednisolone group and 6·0 days (IQR 5·0-8·8) in the intravenous immunoglobulins group (estimated effect size -0·037 of the log(10) transformed times, 95% CI -0·13 to 0·065, p=0·42). Fewer patients in the methylprednisolone group (ten [27%] of 37) required respiratory support compared with the intravenous immunoglobulin group (21 [55%] of 38, p=0·025). Need and duration of inotropes, admission to intensive care units, cardiac events after baseline, and major bleeding and thrombotic events were not significantly different between the study groups. INTERPRETATION In this RCT, treatment with methylprednisolone in children with PIMS-TS did not significantly affect the length of hospital stay compared with intravenous immunoglobulins. Intravenous methylprednisolone could be an acceptable first-line treatment in children with PIMS-TS. FUNDING NOMIS Foundation, Vontobel Foundation, and Gaydoul Foundation.

Gamma globulin combined with acyclovir for children with infectious mononucleosis and their effect on immune function
Li, Y., Chen, B.
American journal of translational research. 2023;15(6):4399-4407
Abstract
BACKGROUND Infectious mononucleosis (IM) is characterized by pharyngitis, cervical lymphadenopathy, fatigue and fever. IM is most commonly seen in primary Epstein-Barr virus (EBV) infection, with higher occurrence in children. OBJECTIVE To explore the value of gamma globulin combined with acyclovir for IM children and their impact on immune function. METHODS This prospective randomized controlled study recruited 111 children under 14 years old with IM from Anhui Provincial Children's Hospital during March 2019 and March 2022. Among them, 11 children dropped out, and 100 eligible children were randomized 1:1 into a control group and a study group. The control group received acyclovir, and the study group received additional gamma globulin. The baseline data, clinical efficacy, immune function, and adverse reactions were collected and compared. RESULTS The study group had a shorter antipyretic time, lymph node reduction time, pharyngitis improvement time, and hospital stay compared to the control group (P < 0.05). The study group yielded lower levels of total white blood cell count, alanine aminotransferase, and creatine kinase-MB than the control group (P < 0.05). After treatment, the levels of CD3+ and CD8+ were lower, and the levels of CD4+, CD4+/CD8+, IgA, and IgG were higher in the study group than those in the control group (all P < 0.05). The incidence of adverse reactions between the two groups was comparable (14.00% vs. 24.00%). The positive rates of EBV-specific antibody and nuclear antigen in the study group were lower than those in the control group (P < 0.05). CONCLUSION The combined treatment of gamma globulin and acyclovir is a promising alternative for patients with IM compared to acyclovir alone. This combined regimen shortens the duration of clinical manifestations in children, promotes the recovery of laboratory indices, improves clinical efficacy, and enhances immune function. Furthermore, its safety profile is acceptable, warranting its further promotion.

Abstract
OBJECTIVE To investigate whether intravenous immunoglobulin (IVIG) improves neurological outcomes in children with encephalitis when administered early in the illness. DESIGN Phase 3b multicentre, double-blind, randomised placebo-controlled trial. SETTING Twenty-one hospitals in the UK. PARTICIPANTS Children aged 6 months to 16 years with a diagnosis of acute or subacute encephalitis, with a planned sample size of 308. INTERVENTION Two doses (1 g/kg/dose) of either IVIG or matching placebo given 24-36 hours apart, in addition to standard treatment. MAIN OUTCOME MEASURE The primary outcome was a 'good recovery' at 12 months after randomisation, defined as a score of≤2 on the Paediatric Glasgow Outcome Score Extended. SECONDARY OUTCOME MEASURES The secondary outcomes were clinical, neurological, neuroimaging and neuropsychological results, identification of the proportion of children with immune-mediated encephalitis, and IVIG safety data. RESULTS 18 participants were recruited from 12 hospitals and randomised to receive either IVIG (n=10) or placebo (n=8) between 23 December 2015 and 26 September 2017. The study was terminated early following withdrawal of funding due to slower than anticipated recruitment, and therefore did not reach the predetermined sample size required to achieve the primary study objective; thus, the results are descriptive. At 12 months after randomisation, 9 of the 18 participants (IVIG n=5/10 (50%), placebo n=4/8 (50%)) made a good recovery and 5 participants (IVIG n=3/10 (30%), placebo n=2/8 (25%)) made a poor recovery. Three participants (IVIG n=1/10 (10%), placebo n=2/8 (25%)) had a new diagnosis of epilepsy during the study period. Two participants were found to have specific autoantibodies associated with autoimmune encephalitis. No serious adverse events were reported in participants receiving IVIG. CONCLUSIONS The IgNiTE (ImmunoglobuliN in the Treatment of Encephalitis) study findings support existing evidence of poor neurological outcomes in children with encephalitis. However, the study was halted prematurely and was therefore underpowered to evaluate the effect of early IVIG treatment compared with placebo in childhood encephalitis.

Wang, Q. Q., Zheng, L. Y., Zhao, S.
The Turkish journal of pediatrics. 2023;65(4):640-649
Abstract
BACKGROUND Even though intravenous immunoglobulin (IVIG) is a current treatment for Kawasaki disease (KD), 10-20% of patients require additional therapy. This study seeks to investigate the therapeutic effects of glucocorticoids plus IVIG on KD and to ascertain the subsequent effect on platelet activation during the acute phase. METHODS A total of 32 children with KD were randomly classified into two groups: the experimental group (16 cases) and the control group (16 cases). The control group was exposed to IVIG (2 g/kg), whereas children in the experimental group were treated with IVIG (2 g/kg) + glucocorticoid. Peripheral venous blood samples were obtained from all participants before treatment as well as three days post-treatment to test platelet activation levels with procaspase activating compound-1 (PAC-1) antibody, Toll-like receptor 4 (TLR4), interleukin-6 (IL- 6), tumor necrosis factor-α (TNF-α), procalcitonin (PCT), and C-reactive protein (CRP). Fever duration posttreatment was documented for both groups. Additionally, the coronary arteries in both groups were evaluated during three months of treatment. RESULTS After treatment, the experimental group had remarkably lower levels of TNF-α, CRP, PCT, IL-6, PAC- 1, and TLR4 relative to the control group. The fever persistence rate was considerably elevated in the control group compared to the experimental group (log-rank, P=0.024). In addition, the z-score of coronary artery size dropped after IVIG + glucocorticoids treatment compared to the control group, although this difference was not significant. CONCLUSIONS The IVIG + glucocorticoids can quickly mitigate the inflammatory response and platelet activation. Moreover, it can also improve clinical symptoms in children with KD.

Abstract
The objective of this study was to investigate the clinical effect of early administration of human immunoglobulin in children with severe hand, foot and mouth disease (HFMD) and its influence on serum c-reactive protein (CRP), creatine kinase (CK), and creatine kinase isoenzyme (CK-MB). One hundred and forty children with severe HFMD were randomly divided into Group A (n=70) and Group B (n=70) according to the random number table method. Group A was treated with routine treatment. Group B was treated with routine treatment, and an early intravenous injection of human immunoglobulin. Serum CRP, CK, and CK-MB in Group B were lower than those in Group A after treatment (all p <0.001). The total clinical effective rate of Group B was 92.9%, which was higher than that of Group A (80.0%, p=0.026). Early administration of human immunoglobulin may reduce the levels of serum markers CRP, CK, and CK-MB in children with severe HFMD. Key Words: Human immunoglobulin, Children, HFMD (Hand, foot and mouth disease).
PICO Summary
Population
Children with severe hand, foot and mouth disease (n= 140).
Intervention
Routine treatment + early intravenous injection of human immunoglobulin (n= 70).
Comparison
Routine treatment (n= 70).
Outcome
Serum c-reactive protein, creatine kinase, and creatine kinase isoenzyme in children who received routine treatment were lower than those who received the routine treatment + human immunoglobulin after treatment. The total clinical effective rate of routine treatment + human immunoglobulin was 92.9%, which was higher than that of routine treatment (80.0%).

Abstract
BACKGROUND & AIMS This randomized controlled trial (RCT) was conducted with the aim to evaluate the efficacy and safety of using ROTEM-based transfusion strategy in cirrhotic children undergoing invasive procedures. METHODS This was a open-label, RCT which included (i) children under 18 years of age with liver cirrhosis; (ii) INR between 1.5 and 2.5; and/or (iii) platelet count between 20x10(9) /L to 50x10(9) /L (for procedures other than liver biopsy) and between 40x10(9) /L to 60x10(9) /L (for liver biopsy); and (iv) listed for invasive procedures. Stratified randomization was done for children undergoing liver biopsies. Patients randomized to the ROTEM and conventional groups received blood component transfusion using predefined criteria. RESULTS A total of 423 invasive procedures were screened for inclusion of which 60 were randomized (30 in each group with comparable baseline parameters). The volume of total blood components, fresh frozen plasma (FFP) and platelets transfused was significantly lower in ROTEM as compared to conventional group. Only 46.7% of children in ROTEM group received a blood component compared to 100% in conventional group (p<0.001). The requirement of FFP (ROTEM 43.3%, Conventional: 83.3%, p = 0.001) was significantly lower in the patients receiving ROTEM guided transfusions. There was no difference in procedure related bleed and transfusion related complications between the 2 groups. ROTEM was cost effective (p=0.002) despite the additional cost of the test. CONCLUSION ROTEM-based transfusion strategies result in lower blood component transfusion in cirrhotic children undergoing invasive procedures without an increase in risk of procedure-related bleed. ROTEM-guided transfusion strategy is cost-effective.
