The Relationship between Blood Groups and Mortality in Patients with Acute Pancreatitis

Objective: The potential association between blood group and outcomes in acute pancreatitis has not been adequately explored. This study aimed to investigate the relationship between blood group and in-hospital mortality in patients diagnosed with acute pancreatitis. Methods: We conducted a single-center, retrospective study reviewing the medical records of patients diagnosed with acute pancreatitis between 2022 and 2023. Patient demographics, blood group type, disease severity, and in-hospital mortality were recorded. The correlation between blood group and in-hospital mortality was examined. Results: The blood group distribution among the acute pancreatitis patients was as follows: O: 31.3%, A: 49.2%, B: 16%, and AB: 3.5%. Mortality rates varied across the blood groups, with Group O having the highest mortality (8.3%), followed by Groups B (4.1%) and A (3.3%). Conclusion: Our preliminary findings suggest a potential association between blood group and mortality in acute pancreatitis, with blood group O associated with a higher mortality rate. However, due to the limitations inherent in the study’s retrospective design, these findings should be validated in future prospective studies. Understanding the role of blood group in the prognosis of acute pancreatitis could provide valuable insights into the disease’s pathophysiology and contribute to improved risk stratification and patient management.
