Specific Epstein-Barr Virus Infection Immune Response in Children with Hemophagocytic Lymphohistiocytosis and B cell Lymphoid Malignancies.

The article focuses on several pediatric clinical studies conducted at Ain Shams University and other institutions, addressing diverse medical conditions. One study evaluated the diagnostic accuracy of beef-specific IgE serum measurement compared to oral food challenge in children with cow milk allergy, finding that not all milk-allergic children react to beef. Another clinical trial assessed the effects of L-carnitine supplementation on cardiovascular function and seizure control in children with drug-resistant epilepsy on a ketogenic diet, reporting improvements in convulsion frequency and certain echocardiographic parameters. A pilot study investigated CD27 deficiency in children with Epstein-Barr Virus (EBV) infection, B-cell lymphoid malignancies, and hemophagocytic lymphohistiocytosis, noting an association between CD27 deficiency and chronic EBV infection. Additionally, a study compared hemodynamic changes in preterm infants receiving different noninvasive respiratory supports, finding variations in treatment failure rates and cardiovascular parameters among nasal high-frequency oscillatory ventilation, Vapotherm, and CPAP groups. Lastly, a cross-sectional study examined the relationship between serum magnesium levels and insulin resistance in obese children, identifying low magnesium intake and deficiency in a majority of participants.
