Combination of Hemoglobin-for-Age Z-Score and Plasma Hepcidin Identified as a Novel Predictor for Kawasaki Disease.

Children (Basel) 2022 Jun 18;9(6). Epub 2022 Jun 18.

Kawasaki Disease Center, Kaohsiung Chang Gung Memorial Hospital and Chang Gung University College of Medicine, Kaohsiung 833, Taiwan.

Kawasaki disease (KD) is a febrile coronary vasculitis that affects younger children and includes complications such as coronary artery aneurysm. KD diagnoses are diagnosed based on clinical presentations, a process that still poses a challenge for front-line physicians. In the current study, we developed a novel predictor using the hemoglobin-for-age z-score (HbZ) and plasma hepcidin to differentiate Kawasaki disease (KD) from febrile children (FC). Read More

Human Mobility and Droplet-Transmissible Pediatric Infectious Diseases during the COVID-19 Pandemic.

Int J Environ Res Public Health 2022 Jun 6;19(11). Epub 2022 Jun 6.

Department of Pediatrics, Tokyo Women's Medical University Yachiyo Medical Center, 477-96 Owada-Shinden, Yachiyo 276-0046, Chiba, Japan.

The study tested the hypothesis that human mobility may be a potential factor affecting reductions in droplet-transmissible pediatric infectious diseases (PIDs) during the coronavirus disease-2019 (COVID-19) pandemic mitigation period in 2020. An ecological study was conducted using two publicly available datasets: surveillance on infectious diseases collected by the Japanese government and COVID-19 community mobility reports presented by Google. The COVID-19 community mobility reports demonstrated percentage reductions in the movement of people over time in groceries and pharmacies, parks, and transit stations. Read More

[Pediatric expert consensus on the application of aspirin in Kawasaki disease].

Zhongguo Dang Dai Er Ke Za Zhi 2022 Jun;24(6):597-603

Kawasaki disease (KD) is one of the common acquired heart diseases in children aged <5 years and is an acute systemic vasculitis. After nearly 60 years of research, intravenous immunoglobulin combined with oral aspirin has become the first-line treatment for the prevention of coronary artery lesion in acute KD; however, there are still controversies over the role and optimal dose of aspirin. The consensus was formulated based on the latest research findings of KD treatment in China and overseas and comprehensive discussion of pediatric experts in China and put forward recommendations on the dose, usage, and course of aspirin treatment in the first-line treatment of KD.

Efficacy of Anakinra on Multiple Coronary Arteries Aneurysms in an Infant with Recurrent Kawasaki Disease, Complicated by Macrophage Activation Syndrome.

Children (Basel) 2022 May 5;9(5). Epub 2022 May 5.

Department of Clinical-Surgical Diagnostic and Pediatric Sciences, University of Pavia, 27100 Pavia, Italy.

Kawasaki disease (KD) is rare in infants less than 3 months of age, and its recurrence is exceptional. Infants with KD are at higher risk of severe clinical presentation, therapy failure, complications and coronary aneurysms (CAAs), and this is the reason they deserve more aggressive therapy and a strict clinical follow-up. We report a 2-month-old male with KD, complicated by Macrophage Activation Syndrome (MAS). Read More

Cross-reactive immunity against the SARS-CoV-2 Omicron variant is low in pediatric patients with prior COVID-19 or MIS-C.

Nat Commun 2022 May 27;13(1):2979. Epub 2022 May 27.

Division of Pediatric Critical Care, University of Minnesota Masonic Children's Hospital, Minneapolis, MN, 55454, USA.

Neutralization capacity of antibodies against Omicron after a prior SARS-CoV-2 infection in children and adolescents is not well studied. Therefore, we evaluated virus-neutralizing capacity against SARS-CoV-2 Alpha, Beta, Gamma, Delta and Omicron variants by age-stratified analyses (<5, 5-11, 12-21 years) in 177 pediatric patients hospitalized with severe acute COVID-19, acute MIS-C, and in convalescent samples of outpatients with mild COVID-19 during 2020 and early 2021. Across all patients, less than 10% show neutralizing antibody titers against Omicron. Read More
