Predictive value of immature granulocyte percentage and neutrophil lymphocyte ratio in terms of prognosis in the course of acute pancreatitis.

Abstract

Aim: We aimed to investigate the role and importance of immature granulocyte percentage and neutrophil/lymphocyte ratio in the etiology, diagnosis and follow-up of acute pancreatitis (AP) in patients tentatively diagnosed with AP in the emergency department. We evaluated these factors alongside other established markers proven effective in the diagnosis and follow-up of AP.

Material and methods: A total of 139 patients with a tentative diagnosis of acute pancreatitis who were hospitalized and followed up in the gastroenterology clinic in 2021‒2022 were included in the study. In addition, a control group, consisting of 139 individuals admitted to the clinic for various other reasons, was established. The cases were also compared with the control group in terms of NLR, ICG and IG%.

Results: There was a significant difference in the NLR, IGC and IG% measurements between the patients in the AP group and the control group. In all three markers, the average values of the patient group were higher than those of the control group. Furthermore, a significant difference in IGC and IG% blood measurements was noted between sub-groups of patients categorized based on the severity of acute pancreatitis, particularly the patients with severe pancreatitis exhibited higher mean IGC and IG% blood measurements compared to those with mild or moderate pancreatitis.

Conclusion: IGC and IG% values emerged as superior indicators to other acute-phase reactants for detecting inflammation, determining its severity, and establishing prognosis in acute pancreatitis. While the N/L ratio remains an important parameter in acute pancreatitis, our findings indicate that it was not significantly superior to other investigated markers in terms of prognosis (Tab. 5, Ref. 35).
