The Prognostic Value of the Neutrophil–Lymphocyte Ratio (NLR) in Acute Pancreatitis: Identification of an Optimal NLR

Abstract

Elevation of the NLR during the first 48 h of admission is significantly associated with severe acute pancreatitis and is an independent negative prognostic indicator in AP.

Association between the neutrophil-to-lymphocyte ratio, a new marker of systemic inflammation, and restless legs syndrome

“…(21) The NLR, a new and inexpensive marker, provides a simple method to assess inflammatory status. High NLR values were found in cases of acute or chronic inflammation, such as acute pancreatitis, (22) chronic tonsillitis, (23) acute mesenteric ischaemia, (24) coronary artery disease, (9) heart failure, (10) diabetes mellitus (11) and other malignancies. (12,13) However, some limitations of our study should be noted.…”

Diagnostic utility of the neutrophil-to-lymphocyte ratio in patients with acute mesenteric ischemia: A retrospective cohort study

“…Yu et al [22] found that preoperative NLR was prognostic for gastric cancer patients. Suppiah et al [23] found that NLR elevation during the first 48 hours of admission was significantly associated with severe acute pancreatitis, and was an independent (negative) prognostic factor. Kahramanca et al [24] found preoperative NLR useful in the diagnosis of acute appendicitis, as well as in the differentiation of patients with simple and complicated appendicitis.…”

The Utility of Neutrophil to Lymphocyte Ratio as a Predictor of Intervention in Acute Diverticulitis

“…The principle behind NLR is that neutrophil levels rise as part of the inflammatory cascade, whereas lymphocytes are depleted during sepsis. Measuring the divergence between these 2 WBC components is believed to be more accurate at predicting poor clinical outcome than measuring each one individually [12] . A recent retrospective study by Hogan et al [13] assessed the role of NLR in the setting of acute diverticulitis.…”
