Utilization of CBC-Derived Inflammatory Indices in Assessing Severity and Prognosis of Acute Pancreatitis.

Acute pancreatitis (AP) is a common disease that develops swiftly and has a mortality rate between 1% and 1.5%.

Investigators should therefore identify the severity of AP and the presence of complications early in order to reduce the risk of premature death and devise interventions to reduce mortality. Currently, the majority of conventional methods for assessing the severity of acute pancreatitis have limitations; the majority of these methods are insufficiently basic, rapid, and cost-effective. None of these methods are sufficiently sensitive or specific.

When acute pancreatitis occurs, trypsin is released and the exocrine function of the pancreas is activated, which destroys the pancreatic self-defence mechanism and exacerbates the damage and destruction of pancreatic cells. Consequently, the vascular endothelium is compromised, motor dystonia develops, vascular permeability increases, more leukocytes migrate to tissues, and coagulation systems are activated. Numerous inflammatory markers based on blood cell changes that were inexpensive and easily obtained during the early stages of hospitalisation were used to determine the severity of AP, including the red cell distribution width (RDW), neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet lymphocyte ratio (PLR), total calcium (TC), albumin-corrected calcium (ACC), and blood urea nitrogen (BUN). However, there is little literature that compares their predictive functions comprehensively.

Because inflammatory mediators play a crucial role in the occurrence of AP, numerous inflammatory markers have recently been used to predict the prognosis of AP. SII is one of the new inflammatory markers that indicates the immune status. SII is a measure of systemic immune-inflammation based on neutrophils, lymphocytes, and platelets. SII was previously only associated with the prognosis of cancer patients; however, it has recently been applied to inflammation-related diseases.

In patients with severe acute pancreatitis (AP), numerous pancreatic cells are damaged, and as a result, inadequate insulin secretion can result in stressful fluctuations in blood glucose level. Blood glucose fluctuations are believed to cause irreversible organ injury and impact patient prognosis.
