Changes and correlations of T-cell coinhibitory molecule programmed death-1 and interferon-γ in pediatric immune thrombocytopenia
Fady Mohamed El-Gendy, Amira M.F. Shehata, Esam Awad Abd El-Kawy, Mahmoud Ahmed El-Hawy
Clin Exp Pediatr. 2023;66(3):127-133.   Published online February 24, 2023
Question: What are the PD-1+ CD4+ T cells percentages and serum interferon gamma (IFN-γ) levels of pediatric patients with immune thrombocytopenia (ITP)?
Finding: Compared with healthy controls, the PD-1+ CD4+ T cells percentages and IFN-γ levels were significantly higher in ITP patients before and 1 month after therapy.
Meaning: Our findings suggest that PD-1+ CD4+ T cells and IFN-γ are involved in the pathophysiological process of ITP.

Usefulness of interferon-γ release assay for the diagnosis of latent tuberculosis infection in young children
Ki Wook Yun, Young Kwang Kim, Hae Ryun Kim, Mi Kyung Lee, In Seok Lim
Clin Exp Pediatr. 2016;59(6):256-261.   Published online June 30, 2016
Purpose

Latent tuberculosis infection (LTBI) in young children may progress to severe active tuberculosis (TB) disease and serve as a reservoir for future transmission of TB disease. There are limited data on interferon-γ release assay (IGRA) performance in young children, which our research aims to address by investigating the usefulness of IGRA for the diagnosis of LTBI.

Clin Exp Pediatr. 2009;52(5):519-528.   Published online May 15, 2009
Tuberculosis continues to cause an unacceptably high toll of disease and death among children worldwide. Whereas intense scientific and clinical research efforts into novel diagnostic, therapeutic, and preventive interventions have focused on tuberculosis in adults, childhood tuberculosis has been relatively neglected. However, children are particularly vulnerable to severe disease and death following infection, and those with latent infection become the...
