简要总结
This prospective observational study aims to evaluate the prognostic value of complete blood count (CBC)-derived inflammatory indices, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII), for predicting severe acute pancreatitis and 28-day mortality in adult patients admitted with acute pancreatitis.
详细描述
Acute pancreatitis (AP) ranges from mild self-limiting disease to severe forms associated with persistent organ failure, infected necrosis, and substantial mortality. Early identification of patients at high risk of severe disease is essential for appropriate triage and management.
CBC-derived inflammatory indices such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) are inexpensive and widely available markers that have demonstrated prognostic value in critical illness. Their specific role in predicting severity and mortality in acute pancreatitis requires further evaluation.
This prospective observational study will assess admission and early serial CBC-derived indices as predictors of severe acute pancreatitis (defined by the revised Atlanta criteria) and 28-day all-cause mortality, and will compare their predictive performance with standard clinical severity scores including APACHE II and BISAP.
