Association between Interleukin-17F 7488A/G and 7383A/G polymorphisms and susceptibility to juvenile idiopathic arthritis.

Background: Interleukin-17F (IL-17F), one of the cytokines, is crucial in the pathophysiology of juvenile idiopathic arthritis (JIA). Therefore, we aimed to determine the relation between IL17F 7488A/G and IL17F 7383A/G single-nucleotide polymorphisms and JIA susceptibility and to explain their impact on the disease activity.

Methods: Genomic DNA of 70 patients with JIA and 70 age and sex-matched controls were extracted and typed for IL17F 7488A/G and IL17F 7383A/G single-nucleotide polymorphisms, using polymerase chain reaction with sequence-specific primers method, and compared between patients and controls.

Tracheal aspirate presepsin: a promising biomarker in early onset neonatal pneumonia.

The early recognition and management of early-onset neonatal pneumonia is a challenge facing intensivists. Presepsin is an emerging immunologic and inflammatory biomarker that has been used for early non-culture-based detection of infection. We aimed to clarify the potential of presepsin assessed in tracheal aspirate of newborns to identify pneumonia.

Clusterin in atopic and non-atopic childhood asthma.

Several biomarkers have been studied to diagnose or to detect the phenotype of asthma. Clusterin is a sensitive cellular biosensor of oxidative stress and has been studied as a biomarker for inflammatory diseases. We aimed to study serum clusterin level in atopic versus non-atopic childhood asthma and its relation to disease severity.

Importance of Studying the Levels of Hepcidin and Vitamin D in Egyptian Children with Chronic Hepatitis C.

Background And Objective: Hepcidin is the key regulator of iron metabolism and is a significant biomarker for systemic inflammatory states. Vitamin D is a powerful immunomodulator and plays a significant role in the inflammatory responses and fibrosis occurring due to hepatitis C virus (HCV) infection. This study assessed the level of vitamin D and serum hepcidin and its expression in peripheral blood of children with chronic hepatitis C (CHC) and correlated them with other serum markers to reflect iron metabolism and liver disease severity.

Association of interleukin (IL)-4 variable number of tandem repeats (VNTRs) and IL-4-590 promoter polymorphisms with susceptibility to pediatric autoimmune hepatitis type 1.

Objective: Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease mediated by an autoimmune reaction to hepatocytes, the present study aimed to assess the possible associations between interleukin-4 (IL-4) variable number of tandem repeats (VNTRs) and IL-4-590 promoter polymorphisms and susceptibility to autoimmune hepatitis type 1 in children.

Subjects And Methods: The study was performed on 101 children diagnosed with AIH and 104 apparently healthy, age and sex-matched control children, diagnosis of AIH was based on the simplified score for the diagnosis of AIH. Genotyping for the IL-4 VNTR and IL-4-590 were performed using PCR-RFLP.

Role of serum cystatin-C and beta-2 microglobulin as early markers of renal dysfunction in children with beta thalassemia major.

Background: Although advancements have been made in the management of thalassemic patients, many unrecognized complications have emerged, such as renal abnormalities.

Aim: To measure serum levels of cystatin-C and β-2 microglobulin in children with beta-thalassemia major (β-TM) and investigate their significance as early markers of glomerular and tubular dysfunctions.

Subjects And Methods: The study was performed on 70 children with (β-TM) and 20 apparently healthy children matched for age and sex as a control group.

Predictive and diagnostic value of serum intestinal fatty acid binding protein in neonatal necrotizing enterocolitis (case series).

Objectives: In this study, we aimed to investigate the value of serum intestinal fatty acid binding protein (I-FABP) in early diagnosis and predicting the severity of Necrotizing enterocolitis (NEC).

Methods: This prospective study was performed on 160 preterm neonates ageing less than 35 weeks and weighting less than 2000 gm selected from the Neonatal Intensive Care Units (NICUs) of the Pediatric Department at Benha University hospital and Benha children hospital to evaluate which of them will develop NEC, after follow-up these neonates were divided into two groups: Group one compromised eighteen preterm neonates with symptoms and signs of NEC. Group two compromised ten preterm neonates as a control group.

Predictive value of IL-35 and IL-17 in diagnosis of childhood asthma.

This study aimed to evaluate the correlation between serum levels of IL-17 and IL-35 and the presence and severity of childhood asthma. The study was performed on 60 diagnosed asthmatic children, who were further classified into four groups according to the Global Initiative for Asthma Guidelines for Asthma Severity and Control (GINA) 2016, plus 30 age- and sex-matched apparently healthy children. All participants were subjected to full medical history, clinical examination, pulmonary function tests and laboratory evaluation in the form of complete blood count (CBC), serum total IgE, IL-17 and IL-35 by ELISA.
