Introduction: Extracorporeal shock wave lithotripsy (ESWL) causes trauma to the renal parenchyma. Due to the kidney injury, free radicals are generated, and an inflammatory process develops. Inflammatory markers like interleukin's (IL), C-reactive protein (CRP), and procalcitonin (PCT) are released into the circulation.

Background: The COVID-19 (SARS-CoV-2) epidemic has posed a major challenge to global public health, especially in children. Some children may experience secondary infection with Mycoplasma pneumoniae after SARS-CoV-2 infection, which has attracted widespread attention. Studies have shown that eosinophils play an important role in respiratory tract infections and are involved in regulating immune responses and inflammatory processes.

Aim: We aimed to investigate the prevalence and factors associated with C-reactive protein (CRP) and procalcitonin (PCT) discordance in febrile infants with serious bacterial infections (SBIs).
Methods: We performed a retrospective review of febrile infants ≤ 90 days old presenting to the emergency department between December 2018 and June 2023. We compared conservative and pragmatic thresholds for PCT (< 0.

Introduction: The escalating resistance of microorganisms to antimicrobials poses a significant public health threat. Strategies that use biomarkers to guide antimicrobial therapy-most notably Procalcitonin (PCT) and C-reactive protein (CRP)-show promise in safely reducing patient antibiotic exposure. While CRP is less studied, it offers advantages such as lower cost and broader availability compared with PCT.
