Relationship of the CRP/albumin ratio and the systemic immune-inflammation index with Forrest classification in patients with gastrointestinal bleeding

Abstract

Aim: The present study aimed to investigate CRP/albumin ratio and the systemic immune-inflammation index (SII) and Forrest classification in patients who presented to the emergency department with acute upper gastrointestinal (GI) bleeding. 
 Materials and Method: Patients over 18 years of age who presented to the emergency department of our hospital with melena, hematemesis, and hematochezia and were diagnosed with upper GI bleeding via esophagoduodenoscopy were included in the study. Esophagoduodenoscopy results, and accordingly, the Forrest classifications, together with complete blood count, including hemoglobin, platelet, and neutrophil values, as well as demographic characteristics were recorded. SII (calculated by multiplying the platelet count with neutrophil count and dividing the value obtained by the lymphocyte count [platelet (P)×neutrophil (N)/lymphocyte (L)]) and CRP/albumin ratio was calculated.
 Results: No statistically significant difference was observed among the Forrest classification groups in terms of the median SII values as well as median CRP/albumin ratios. However, a statistically significant difference in median CRP/albumin ratios was observed among the dichotomized Forrest classification groups. 
 Conclusion: The SII is not a reliable parameter either predicts GI bleeding or the Forrest classification in patients with upper GI bleeding. The CRP/albumin ratio might be a poor predictor of bleeding; however, it can not predict the Forrest classification.
