The value of hematological parameters in acute pancreatitis.

Background: Acute pancreatitis (AP) is a common inflammatory disease in the emergency department (ED). This study aims to assess the role of CRP and hematologic parameters in mild/severe AP patients and biliary/nonbiliary AP at the time of admission to the ED.

Methods: 168 patients who were diagnosed as AP in the ED, and as a control group, 100 patients were included in this study. At the time of application to the ED, the demographic information (age, sex) and the amylase, lipase, CRP, hematological parameters (WBC, MPV, RDW, PLT, NLR) of all patients and the control group were recorded and compared. According to the etiology of the patients, the patients were divided into biliary and nonbilary AP groups and according to the severity, they were divided into mild and severe AP groups, then, the same parameters were evaluated.

Results: Significant differences were found out between WBC, CRP, NLR, MPV and PLT values between patient and the control group (p<0.001). The length of hospitalization and the parameters were not significant between the biliary and the nonbiliary group. Ranson and APACHE II scores were correlated with WBC, CRP and NLR. There was a statistically significant difference between the mild and severe AP groups in terms of duration of the hospital stay, CRP, WBC and NLR values (p=0.003 for CRP, p<0.001 for the others). In severe AP, the cut-off value of NLR was found to be 8.05, sensitivity %93.48, specificity %86.89 and AUC 0.937 (p<0.001).

Conclusion: The use of parameters, such as WBC, CRP, and NLR, in combination with other diagnostic and prognostic tools in emergency service can provide convenience to clinicians at the time of admission and prognosis.
