Abstract :Background: Pneumonia causes the majority of acute respiratory distress syndrome (ARDS) cases. The microbes that cause pneumonia are very diverse. In addition to DNA, RNA viruses, Gram-negative and Gram-positive bacteria cause two types of cytokine imbalances, anti-inflammatory and pro-inflammatory. It can also influence the progno-sis of sepsis and other infectious diseases. This study aims to search for 8-hydroxy-2\'-deoxyguanosine (8-OHdG), IL-21, IL-23, and c-reactive protein (CRP) and compare cytokine levels. It is also to determine if Pediatric pneumonia patients CRP and cytokine levels correlate with results. Materials and Methods: In the study, blood was drawn from approximately 43 pediatric pneumonia patients and 43 healthy controls who came to the pediatric clinic to investigate serum IL-21, IL-23, 8-OHdG, and CRP levels. The levels of biomarkers were determined by ELISA method. Serum CRP levels were measured using the ATELLICA IM Analyzer. Results: Serum CRP, 8-OHdG, IL-21 and IL-23 levels were significantly higher in the pediatric pneumonia patient group than in the control group. Conclusions: Increased serum IL-21, IL-23, 8-OHdG and CRP expression in pediatric pneumonia patients is a poten-tial determinant suggesting that IL-21, IL-23-related cytokines may play a role in endothelial cell activation reported in patients. Increased 8-OHdG oxidative stress is more pronounced in patients without pediatric pneumonia while pro inflammatory cytokines are higher in pediatric pneumonia patients. However, it is used as a possible therapeu-tic target to reduce inflammation. Further study on the impact of these findings on comorbidities with larger num-ber test size is neededKeywords : Pneumonia, IL-21, IL-23, 8-OHdG
