Polymorphism of interleukin-1β and interleukin-1 receptor antagonist genes in children with autism spectrum disorders.

In this study, we first investigated interleukin-1 beta (IL-1β) and IL-1 receptor antagonist (IL-1RA) levels in a cohort of Egyptian children with autism spectrum disorder (ASD) and in healthy controls. Second, we examined the single-nucleotide polymorphisms (SNPs) at positions -31 and - 511 of the IL-1β gene promoter and IL1RA and assessed the association between IL1B and IL1RA polymorphisms with ASD. We examined IL1β promoter polymorphism at -511 (IL-1β-511) and - 31 (IL-1β-31) and IL1RA gene polymorphism in 80 children with ASD and 60 healthy children.

Effect of Hydroxyurea Treatment on the Inflammatory Markers Among Children With Sickle Cell Disease.

Background: Neutrophil-to-lymphocyte ratio (NLR) was introduced as a potential inflammatory marker in sickle cell disease (SCD). This study aimed to evaluate the impact of hydroxyurea (HU) treatment on the value of NLR and some inflammatory mediators in SCD.

Methods: The hematological parameters and clinical events were analyzed in 35 children with SCD under HU treatment and followed up for 1 year and in 20 healthy controls.

High dose dexamethasone as an alternative rescue therapy for active bleeding in children with chronic ITP: clinical and immunological effects.

High-dose dexamethasone (HD-DXM) is debated as a second-line therapy for chronic Immune thrombocytopenia (ITP) in children. The aim of this study is to evaluate the efficacy and safety of HD-DXM as an emergency therapy in uncontrolled bleeding in children with chronic ITP and to assess its immunological effect on dendritic cells (DCs) percentage and their co-stimulatory markers CD86 and CD83. Totally, 20 children previously diagnosed as chronic ITP were enrolled in this study and all admitted to hospital with uncontrolled bleeding.

Neurologic Complications in Children With Scorpionism: A Retrospective Study in Upper Egypt.

Scorpion envenomation is a life-threatening health problem in tropical and subtropical regions, particularly among children. The aim of this study was to describe the epidemiologic characteristics, clinical profile, and prognosis of neurologic complications among children with scorpionism in Upper Egypt. In this retrospective study, the neurologic complications of scorpionism in 2 university hospitals were analyzed from the points of epidemiologic and clinical picture and outcomes.

Randomized controlled trial of vitamin D supplementation in children with autism spectrum disorder.

Background: Autism spectrum disorder (ASD) is a frequent developmental disorder characterized by pervasive deficits in social interaction, impairment in verbal and nonverbal communication, and stereotyped patterns of interests and activities. It has been previously reported that there is vitamin D deficiency in autistic children; however, there is a lack of randomized controlled trials of vitamin D supplementation in ASD children.

Methods: This study is a double-blinded, randomized clinical trial (RCT) that was conducted on 109 children with ASD (85 boys and 24 girls; aged 3-10 years).

Effects of bovine colostrum on recurrent respiratory tract infections and diarrhea in children.

Background: Bovine colostrum (BC) has direct antimicrobial and endotoxin-neutralizing effects throughout the alimentary tract, as well as other bioactivities that suppress gut inflammation and promote mucosal integrity and tissue repair under various conditions related to tissue injury. The precise role of BC in respiratory and gastrointestinal (GI) infections in children is not well defined. The aim of this study was to evaluate the efficacy and tolerability of BC administration in preventing recurrent upper respiratory tract infections (URTI) and diarrhea in children.
