Aim: The aim of this study is to investigate the effects of procalcytonin (PCT), C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) on the mortality and duration of hospital stay in patients diagnosed with pneumonia. Material and Method: The study consists of 111 cases of pneumonia followed in our chest diseases service and intensive care unit between 2017 to 2018. Collected data included demographic information, NLR, PCT, CURB-65 scores. The data were evaluated by parametric tests (paired sample T test, independent sample T test). Chi-square test was used in order to compare categorical variables. P value ≤0.05 was considered statistically significant. Results: A statistically significant positive correlation was detected between PCT and NLR (p<0.001; r=0.343), PCT and CRP (p<0.001; r=0.502), NLR and CRP (p<0.001; r=0.427). There was a statistically significant correlation between mortality and CRP (p<0.001; 0.427), mortality and PCT (p<0.001; r=0.343) and mortality and NLR (p=0.013; r=0.235). There was a statistically significant correlation between duration of hospital stay and PCT (p=0.036; r=0.199) duration of hospital stay and NLR (p=0.030; r=0.206) but not with duration of hospital stay and CRP (p=0.298; r=0.102). Conclusion: Besides PCT and CRP, NLR can also be used for prognosis estimation in pneumonia patients.
