Circulating spexins in children with obesity: relation to cardiometabolic risk.

Eur J Clin Nutr 2021 Apr 13. Epub 2021 Apr 13.

Department of Pediatrics, Faculty of Medicine, Ain Shams University, Cairo, Egypt.

Background/objectives: The role of spexin (SPX) in energy metabolism, endocrinal homeostasis, and vasculopathy is emerging. However, scarce data are available about its role in childhood obesity and obesity-related vasculopathy. Hence, we aimed to assess the level of SPX in obese and normal-weight children, and to correlate it with aortic distensibility (AD) and aortic stiffness index (ASI).

Subjects/methods: Forty obese children were compared to 40 matched normal-weighed children. Weight, height, and body mass index (BMI) z score and mean blood pressure (Bl-Pr) percentile on three different occasions were obtained. SPX, fasting triglycerides, cholesterol, low-density (LDL), high-density lipoproteins (HDL), and insulin were measured with calculation of the homeostatic model assessment insulin resistance (HOMA-IR). Internal aortic diameter was measured with calculation of AD, strain (AS), and ASI.

Results: Children with obesity had significantly lower SPX (P = 0.004), HDL (P < 0.001), and AD (P < 0.001) and higher systolic Bl-Pr (P < 0.001), diastolic Bl-Pr (P < 0.001), LDL (P = 0.011), HOMA-IR (P < 0.001), and ASI (P < 0.001). Significant negative correlation was found between SPX and BMI z score (r = -0.646, P < 0.001), systolic Bl-Pr (r = -0.641, P < 0.001), diastolic Bl-Pr (r = -0.427, P < 0.001), HOMA-IR (r = -0.349, P = 0.028), and ASI (r = -0.389, P = 0.013), while significant positive correlation was found between SPX and AS (P < 0.001, r = 0.633) and AD (P < 0.001, r = 0.612). However, no significant correlation was found between SPX and age (r = -0.01, P = 0.953), TG (r = 0.048, P = 0.767), total cholesterol (r = -0.023, P = 0.887), LDL (r = -0.299, P = 0.061), and HDL (r = 0.193, P = 0.232).

Conclusions: Children with obesity had significantly lower SPX than controls. SPX was correlated with BMI, Bl-Pr, HOMA-IR, and vasculopathy in children with obesity independent of their age and lipid profile. Further studies should explore the pathomechanism of SPX and its potential role in the management of obesity and obesity-related cardiometabolic risk.

The "Golden Hours" Algorithm For the Management of the Multisystem Inflammatory Syndrome in Children (MIS-C).

Glob Pediatr Health 2021 27;8:2333794X21990339. Epub 2021 Jan 27.

Ain Shams University, Cairo, Egypt.

The global concern of increasing number of children presenting with multisystem inflammatory syndrome in children (MIS-C) related to the coronavirus disease (COVID-19) has escalated the need for a case-oriented clinical approach that provides timely diagnosis and management. The aim of this study is to share our experience in managing 64 MIS-C patients of North African ethnicity guided by a risk-based algorithm. Sixty-four patients met the inclusion criteria, 19 (30%) patients were categorized as mild and moderate risk groups and cared for in an isolation ward and 45 patients who belonged to the high-risk group (70%) were admitted to the pediatric intensive care unit (PICU). Positive laboratory evidence of COVID-19 was found in 62 patients. Fever and dysfunction in 2 or more organs were confirmed in all cases (100%). Fifty patients (78%) presented with gastrointestinal symptoms, meanwhile only 10 patients (16%) had respiratory manifestations. Cardiac involvement was reported in 55 (86%) cases; hypotension and shock were found in 45 patients (70%) therein circulatory support and mechanical ventilations were needed for 45 and 13 patients respectively. Intravenous immunoglobulins (IVIG) were used for all cases and methylprednisolone was used in 60 patients (94%). Fifty-eight (91%) patients were discharged home after an average of 9 days of hospitalization. The mortality rate was 9% (6 patients). . A single Egyptian center experience in the management of MIS-C patients guided by a proposed bed side algorithm is described. The algorithm proved to be a helpful tool for first-line responders, and helped initiate early treatment with IVIG.

COVID-19 in Children With Cancer: A Single Low-Middle Income Center Experience.

J Pediatr Hematol Oncol 2020 Dec 7. Epub 2020 Dec 7.

Pediatric Hematology Oncology Department.

Background: Coronavirus disease-2019 (COVID-19) could be associated with morbidity and mortality in immunocompromised children.

Objective: The objective of this study was to measure the frequency of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among hospitalized children with cancer and to detect the associated clinical manifestations and outcomes.

Methodology: A prospective noninterventional study including all hospitalized children with cancer conducted between mid-April and mid-June 2020 in Ain Shams University Hospital, Egypt. Clinical, laboratory, and radiologic data were collected. SARS-CoV-2 infection was diagnosed by reverse transcription polymerase chain reaction tests in nasopharyngeal swabs.

Results: Fifteen of 61 hospitalized children with cancer were diagnosed with SARS-CoV-2. Their mean age was 8.3±3.5 years. Initially, 10 (66.7%) were asymptomatic and 5 (33.3%) were symptomatic with fever and/or cough. Baseline laboratory tests other than SARS-CoV-2 reverse transcription polymerase chain reaction were not diagnostic; the mean absolute lymphocyte count was 8.7±2.4×10/L. C-reactive protein was mildly elevated in most of the patients. Imaging was performed in 10 (66.7%) patients with significant radiologic findings detected in 4 (40%) patients. Treatment was mainly supportive with antibiotics as per the febrile neutropenia protocol and local Children Hospital guidance for management of COVID-19 in children.

Conclusions: Pediatric cancer patients with COVID-19 were mainly asymptomatic or with mild symptoms. A high index of suspicion and regular screening with nasopharyngeal swab in asymptomatic hospitalized cancer patients is recommended.

Body Composition in Egyptian Children With Transfusion-dependent Thalassemia: The Impact of Nutrition and Metabolic Profile.

J Pediatr Hematol Oncol 2020 07;42(5):e334-e339

Departments of Pediatrics.

Background: Growth failure is a common complication in children with beta-thalassemia major (β-TM) that has persisted despite major treatment advances. It could stem from malnutrition, especially in those who live in poor countries and who have inadequate nutrient intake.

Aim: The aim of this study was to assess the influence of nutrition on growth, total body composition, and metabolic profile in Egyptian children with β-TM.

Subjects And Methods: This cross-sectional study included 200 children with β-TM and 50 age-matched and sex-matched healthy children. All subjects underwent full clinical assessment, which included assessment of growth and total body composition using anthropometric measurements (weight, height, mid-arm circumference, skinfold thickness, and body mass index) and bioelectric impedance analysis device (TANITA SC330). Nutritional assessment was performed using 24-hour dietary recall. Fasting serum insulin, C-peptide, and fasting serum lipid profile (high-density lipoprotein, low-density lipoprotein, cholesterol, and triglyceride) were measured.

Results: Children with β-TM had a significantly lower mean value of the daily consumption of the studied nutrient elements including kilocalories, protein, carbohydrate, calcium, and phosphorus (P<0.001). β-TM had a negative impact on anthropometric measures; the mean of all measurements recorded in children with β-TM was significantly lower than that in the control group (P<0.001). Children with β-TM had a significant abnormality in lipid profile, with higher triglyceride levels and lower cholesterol, low-density lipoprotein, and high-density lipoprotein than controls. They had significantly lower serum insulin and C-peptide. Age, sex, serum ferritin, and caloric intake have a significant impact on body composition in children with β-TM.

Conclusion: Regular assessment of nutrition is crucial for the health of children with β-TM.

The role of probiotics in children with autism spectrum disorder: A prospective, open-label study.

Nutr Neurosci 2018 Nov 7;21(9):676-681. Epub 2017 Jul 7.

d Department of Pediatrics, Faculty of Medicine , Assiut University , Assiut , Egypt.

Objective: There are limited data on the efficacy of probiotics in children with ASD, therefore, this study aims to evaluate the efficacy and tolerability of probiotics in an Egyptian cohort of children with ASD.

Methods: Gastrointestinal (GI) flora were assessed by quantitative real-time PCR of stool samples of 30 autistic children from 5 to 9 years old. GI symptoms of autistic children were assessed with a modified six-item Gastrointestinal Severity Index (6-GSI) questionnaire, and autistic symptoms were assessed with Autism Treatment Evaluation Checklist (ATEC) before and after 3 months of supplementation of probiotics nutritional supplement formula (each gram contains 100 × 10 colony forming units of three probiotic strains; Lactobacillus acidophilus, Lactobacillus rhamnosus and Bifidobacteria longum).

Results: After probiotic supplementation, the stool PCR of autistic children showed increases in the colony counts of Bifidobacteria and Lactobacilli levels, with a significant reduction in their body weight as well as significant improvements in the severity of autism (assessed by the ATEC), and gastrointestinal symptoms (assessed by the 6-GSI) compared to the baseline evaluated at the start of the study.

Conclusions: We concluded that probiotics have beneficial effects on both behavioral and GI manifestations of ASD. Probiotics (a non-pharmacological and relatively risk-free option) could be recommended for children with ASD as an adjuvant therapy. At this stage, this study is a single center with a small number of patients and a great deal of additional wide-scale randomized controlled trials are needed to critically confirm the efficacy of probiotics in ASD.

Frequency of Dendritic Cells and Their Expression of Costimulatory Molecules in Children with Autism Spectrum Disorders.

J Autism Dev Disord 2017 Sep;47(9):2671-2678

Pediatric Department, Faculty of Medicine, Ain Shams University, Cairo, Egypt.

The aim of our study was to evaluate the frequencies of myeloid dendritic cells (mDCs) and plasmacytoid dendritic cells (pDCs) in children with ASD. Subjects were 32 children with ASD and 30 healthy children as controls. The numbers of mDCs and pDCs and the expression of CD86 and CD80 on the entire DCs were detected by flow cytometry. ASD children had significantly higher percentages of mDCs and pDCs when compared to controls. We found significant inverse relationships between serum 25-hydroxyvitamin D levels and the frequencies of mDCs and pDCs in autistic children. Our data suggested that DCs could play a role in the clinical course of ASD. The relationship of DCs to immune disorders in ASD remains to be determined.
