Prevalence and impact of malnutrition on outcomes and mortality of under-five years children with pneumonia: a study from Upper Egypt.

Malnutrition has adverse impacts on under-five children with pneumonia. The purpose of this study was to address the prevalence and impact of malnutrition on under-five years children with pneumonia, admitted to a tertiary large children hospital in Upper Egypt. This study is a prospective case-control study.

Prevalence and associated risk factors of recurrent otitis media with effusion in children in Upper Egypt.

Objective: We conducted this study to determine the associations of possible risk factors and prevalence of recurrent otitis media with effusion (OME) in a cohort of children in Upper Egypt.

Methods: This was a cross-sectional study undertaken in two tertiary referral centers in Upper Egypt. Associations of possible risk factors with prevalence of recurrent OME were studied.

Dendritic cells and monocyte subsets in children with Gaucher disease.

Background: There are minimal data on the frequencies of monocyte subsets and dendritic cells (DCs) in children with Gaucher disease (GD), as nearly all previous studies have involved adult patients. Consequently, we aimed to describe the changes in these cell subpopulations in children with GD type 1 who were on regular enzyme replacement therapy (ERT).

Methods: This case-control study included 25 children with GD1 and 20 healthy controls.

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.

Peripheral Blood B and T Cell Profiles in Children with Active Juvenile Idiopathic Arthritis.

Juvenile idiopathic arthritis (JIA) is one of the most common autoimmune diseases in children. Our study aimed to evaluate the peripheral blood B and T lymphocyte subpopulations in children with JIA. This case-control study included 20 children with JIA as well as 20 healthy children with matching age and sex as a control group.

Vitamin D Status in Egyptian Children With Allergic Rhinitis.

This study aimed to assess the serum levels of vitamin D in an Egyptian cohort of children with allergic rhinitis (AR) and to evaluate any correlation of vitamin D status with the disease severity. One hundred twenty children with AR and 100 healthy children were included in our study. We studied the serum levels of vitamin D 25(OH)D and 1,25(OH)2D in all participants.

Circulating Microparticles in Children With Sickle Cell Anemia in a Tertiary Center in Upper Egypt.

Sickle cell disease (SCD) is a genetically inherited hemolytic anemia increasingly appreciated as a chronic inflammatory condition and hypercoagulable state with high thrombotic risk. It is associated with disturbed immune phenotype and function and circulating microparticles (MPs) derived from multiple cell sources. This study was carried out to determine MPs profiles in patients with sickle cell anemia (either on hydroxyurea (HU) therapy or those with no disease-modifying therapy) and to compare these profiles with healthy children.

Myeloid-Derived Suppressor Cells and Costimulatory Molecules in Children With Allergic Rhinitis.

Objectives:: The aim of this study is to assess the level of myeloid-derived suppressor cells (MDSCs) and the expression of costimulatory molecules CD80 and CD86 on monocytes and their ligands (CD28) on T-lymphocytes in children with allergic rhinitis (AR).

Methods:: The study included 60 children with AR and 50 controls. Flow cytometry was performed to analyze MDSCs and the expression of costimulatory molecules CD80 and CD86 on monocytes and their ligands (CD28) on T-lymphocytes.

Characterization of Regulatory T Cells in Preterm and Term Infants.

Our study aimed to study regulatory T cells (Tregs) and their expression of CD45RA, HLA-DR, and CD39 in preterm and full-term infants. In an observational study, we used a three-color flow cytometry for determination of Tregs and their expression of CD45RA, HLA-DR, and CD39 in preterm and full-term infants. The percentages of CD4CD25Foxp3, CD39 Tregs, HLA-DR Tregs and the expression of Foxp3 in CD4CD25Foxp3 Tregs cells were significantly lower in neonates when compared to healthy adult controls.

Turner syndrome: review of clinical, neuropsychiatric, and EEG status: an experience of tertiary center.

We reviewed the clinical, neuropsychiatric, and EEG status of 53 turner syndrome (TS) females, aged 3-16 years, in Assiut university hospitals, Upper Egypt. The diagnosis and care of patients with TS in Egypt is still in the developing stage. Hence this study was undertaken to review the details of patients with TS with respect to the pattern of cognitive, psychiatric, and motor dysfunction.
