Fathia Ibrahim Elbassal, Mohamed Abdel Rehim Soliman, Nourhan Hossam Eldin Mohamed, Mai El-Sayad Abd El-Hamid, Hanan Hassan El-Sheity
Clin Exp Pediatr. 2025;68(12):981-990.   Published online September 12, 2025
Question: How does iron overload affect immunity in pediatric patients with transfusion-dependent β-thalassemia major?
Finding: Iron overload in these patients is associated with disrupted natural killer (NK) cell subpopulations, reflecting impaired innate immunity.
Meaning: This highlights the need to monitor immune profile alongside iron status during thalassemia management.

Role of neutrophil elastase in predicting infection among children with chemotherapy-induced febrile neutropenia
Mahmoud A. El-Hawy, Doaa M. Elian, Mai El-Sayad Abd El-Hamid, Esraa T. Allam, Mariam S. Kandeel, Asmaa A. Mahmoud
Clin Exp Pediatr. 2025;68(10):801-807.   Published online June 10, 2025
Question: Can neutrophil elastase (NE) levels predict infection— the primary cause of mortality—among children with hematological malignancies and febrile neutropenia (FN)?
Finding: Elevated levels of NE were found in children with chemotherapy-induced FN and a bacterial infection.
Meaning: Increased NE levels and prolonged FN are important factors associated with mortality risk.

Seham Mohamed Ragab, Wafaa Moustafa Abo ElFotoh, Mahmoud Ahmed El-Hawy, Eman Abdelfatah Badr, Saara Khairat Ali Mostafa, Mai El-Sayad Abd El-Hamid

· Polymorphisms in interleukin (IL)-1B and IL-1 receptor (IL-1R) antagonists may significantly affect the pathogenesis of immune thrombocytopenia (ITP).
· IL-1B and IL-1R antagonist gene polymorphisms are correlated with severity and susceptibility to primary ITP in children.
