The Relationship Between Neutrophil-Lymphocyte and Platelet-Lymphocyte Ratios With Hospital Stays and Mortality in the Emergency Department

Abstract

Background, Most acute pancreatitis scoring is made in the first 48-72 hours or later. Like many inflammatory processes, Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) can be useful in showing the severity and extent of inflammation in acute pancreatitis. Our study aimed to evaluate whether these rates affect mortality according to the NLR and PLR values ​​of patients diagnosed with acute pancreatitis by examining the blood samples taken within the first hour after admission to the emergency department rates are useful in predicting the length of stay., Methods, In our retrospective study, 557 patients applied to our clinic for 4.5 years, whose amylase and lipase values ​​were higher than two times the cut-off value in blood tests and whose CT imaging was compatible with acute pancreatitis were included in the study., Results, The median length of hospitalization of the patients was 4.0 (3.0-6.0) days. Gallstones were detected in 320 (57.5%) patients. Mortality of less than a year was observed in 45 (8.1%) of the study population. Eighteen of the patients (3.2%) showed the need for follow-up in the intensive care unit. A statistically significant relationship was found between mortality and variables hematocrit (HCT), red cell distribution width (RDW),c-reactive protein CRP), glucose, urea, potassium, albumin, PLR, and NLR (p <0.05). A statistically significant correlation was observed between RDW, NLR, glucose, and CRP levels in the two groups divided according to the median value of 4 days we found on hospitalization (p <0.05). According to the graphics and test results obtained by ROC analysis, the mortality status can be predicted at a statistically significant level with PLR and NLR diagnostic tests (p <0.05)., Conclusion, High levels of NLR, PLR, RDW, glucose, CRP, urea, potassium, low albumin and hematocrit values ​​at the first admission in the Emergency Service seem to be associated with increased 1-year mortality in acute pancreatitis.
