Role of CD64 and myeloperoxidase as biomarkers for early diagnosis of sepsis in pediatric intensive care unit.

Globally, sepsis is the primary cause of death for children. While research conducted on adults has a significant impact on the diagnosis and treatment of sepsis in newborns and young children, there are significant factors that are pertinent to pediatrics as well. This prospective case-control study was conducted during the period from August 2020 to October 2022 after approval by the institutional ethical committee.

Mid-term follow-up by speckle tracking and cardiac MRI of children post-transcatheter closure of large atrial septal defects.

This is a case-control study of our experience of mid-term follow-up of 40 children who had a transcatheter closure of very large atrial septal defects group (1). All cases had an atrial septal defect device size more than 1.5 times their weight, a ratio considered a contraindication for trans catheter closure (TCC) in some previous reports.

Genetic association of interleukin 18 (-607C/A, rs1946518) single nucleotide polymorphism with asthmatic children, disease severity and total IgE serum level.

Introduction: Bronchial asthma is a chronic inflammatory disease. Interleukin 18 (IL-18) single nucleotide polymorphisms (SNPs) can influence IL-18 production and activity. IL-18-607C/A and -137 C/G are two of the commonly studied SNPs of IL-18 due to their role in the etiopathogenesis of allergic diseases.

High Serum Endothelin-1 Level is Associated with Poor Response to Steroid Therapy in Childhood-Onset Nephrotic Syndrome.

Nephrotic syndrome (NS) is one of the most common kidney diseases seen in children. It is a disorder characterized by severe proteinuria, hypoproteinemia, hyperlipidemia, and generalized edema resulting from alterations of permeability at the glomerular capillary wall. Endothelin-1 (ET1) has a central role in the pathogenesis of proteinuria and glomerulosclerosis and has a role in assessment of the clinical course of NS in children.

The potential association of tumor necrosis factor-βeta (252 G/A) cytokine gene polymorphism with immune thrombocytopenic purpura among Egyptian children.

Objectives: The main objective of this study was to study tumor necrosis factor beta (TNFB) + 252G/A gene polymorphism, known to be related to autoimmunity, in immune thrombocytopenia (ITP) patients. We also aimed to investigate the association between TNFB + 252G/A polymorphism and susceptibility to develop persistent/chronic ITP.

Methods: One hundred pediatric ITP patients, as well as 50 age- and sex-matched healthy Egyptian subjects, were included.

Vitamin D Receptor (VDR) Gene Polymorphisms (FokI, BsmI) and their Relation to Vitamin D Status in Pediatrics βeta Thalassemia Major.

Vitamin D is critical for calcium, phosphate homeostasis and for mineralization of the skeleton, especially during periods of rapid growth. Vitamin D Deficiency leads to rickets (in children) and osteomalacia (in adults). Expression and activation of the vitamin D receptor (VDR) are necessary for the effects of vitamin D, in which several single nucleotide polymorphisms have been identified especially (FokI, BsmI).

Impact of Prothrombotic Risk Factors in a Cohort of Egyptian Hemophilia A Patients.

Introduction: Hemophilias are a group of related bleeding disorders that show an X-linked pattern of inheritance. The clinical phenotype of severe hemophilia may vary markedly among patients as a result of many factors, including genetic prothrombotic risk factors.

Objectives: Our objective was to study the incidence of the most common prothrombotic risk factors for additive effects among Egyptian patients with hemophilia A and their impact on clinical phenotype; annual bleeding frequency and severity of hemophilic arthropathy, as well as the effect of a single variation in these patients.

Detection of expression of IL-18 and its binding protein in Egyptian pediatric immune thrombocytopenic purpura.

Immune thrombocytopenic purpura (ITP) is an autoimmune disorder, characterized by dysfunctional cellular immunity including the presence of activated platelet specific autoreactive T cells that recognize and respond to autologous platelet antigens. Autoreactive T cells drive the generation of platelet reactive autoantibodies by B cells as well as T-cytotoxic cell-mediated lysis of platelets. Interleukin-18 (IL-18) is a mediator of T helper type 1 cell responses synergistically with IL-12 that initiate and promote host defense and inflammation.
