The role of Copeptin in viral lower respiratory tract infections in child: A prospective case-control study.

Background: Lower respiratory tract infection (LRTI) is a leading cause of morbidity and mortality among children globally. Copeptin, released by the pituitary gland, serves as a biomarker for various conditions and, as a neuroendocrine stress hormone, is useful in acute conditions. This study aimed to determine the role of copeptin levels in LRTI in children and whether it can reliably predict pneumonia severity.

Kidney Involvement in Pediatric COVID-19 Cases: A Single-Center Experience.

In this study, we aimed to assess the effect of household ETS exposure on symptom frequency and clinical severity in children and adolescents with COVID-19.

Materials And Methods: This retrospective study included pediatric cases (<18 years old) with a positive SARS-CoV-2 test, who were admitted to our hospital between 20.
