Abstract :Aim: In children, community-acquired pneumonia insert ignore into journalissuearticles values(CAP); has a high mortality and morbidity rate. Platelet, neutrophil, lymphocyte, monocyte, eosinophil, red cell distributions width insert ignore into journalissuearticles values(RDW);, mean platelet volume insert ignore into journalissuearticles values(MPV);, platelet distributions width insert ignore into journalissuearticles values(PDW);, platelet to lymphocyte ratio insert ignore into journalissuearticles values(PLR);, and neutrophil to lymphocyte ratio insert ignore into journalissuearticles values(NLR); have all been suggested as markers of systemic infection and inflammation. Several research, however, have centered on the clinical significance of blood parameters in pediatric CAP. We aim to determine the diagnostic value of complete blood parameters for CAP and to look into their relationship to disease severity. Material and Method: A retrospective, the cross-sectional study enrolled children aged 3 months to 18 years who were diagnosed with CAP at Ankara Atatürk Sanatorium Training and Research Hospital`s pediatrics clinics between January 2018 and June 2021, as well as age-matched healthy children. CAP case definition was made according to the CAP case definition defined by the World Health Organization insert ignore into journalissuearticles values(WHO);. Patients were evaluated according to the criteria of WHO and British Thoracic Society 2011 guidelines as severe and mild CAP. Results: 400 CAP and 400 control patients were included in the study. The mean age of the CAP group was 2.40±3.20 years and the control group was 2.38±3.17 years. Eosinophil, hemoglobin, MPV, PDW and PLR values of the CAP group was statistically significantly lower; leukocytes, lymphocyte, monocyte, neutrophil, basophil, platelet, RDW, and NLR levels of the CAP group were higher than the control group insert ignore into journalissuearticles values(p<0.05);. 30.3% of the CAP patients had severe disease. The mean age of the severe group was 2.92±3.80 and 2.17±2.88 in the mild group. The ratio of males in the CAP group was 62%, while 80.2% in severe, 54.1% in the mild group insert ignore into journalissuearticles values(p<0.001);.The mean hospitalization length for the severe group was 6.16±2.00 days and 4.89±1.78 days for the mild group insert ignore into journalissuearticles values(p<0.001);. CRP, neutrophils, monocyte, eosinophil, and NLR levels were statistically significantly higher in patients in the severe group than the mild group insert ignore into journalissuearticles values(p<0.001);. In ROC analysis, the area under the characteristic curve insert ignore into journalissuearticles values(AUC); for CRP, monocyte, neutrophils, eosinophil, and NLR was calculated as 0.574, 0.569, 0.601, 0.628, and 0.583, respectively and all found statistically significant insert ignore into journalissuearticles values(p<0.001);. Correlation analysis revealed that CRP had a positive correlation with neutrophil count insert ignore into journalissuearticles values(r=0.231, p=0.011); and NLR insert ignore into journalissuearticles values(r=0.221, p=0.015); in the severe COP patients. Conclusion: Increased neutrophils, eosinophil, monocytes, CRP, and NLR, were predicting the severity of CAP. NLR and neutrophils had a significant correlation with CRP and potential parameters for evaluating the severity of CAP disease.
