BACKGROUND: Tokyo guidelines (TG13/18) are used for the severity assessment of acute cholangitis (AC). Lactate is a clinical marker of tissue hypoxia and disease severity, independent from blood pressure.
AIM: The aim of this study is to investigate the relationship between blood lactate level and TG13/18 criteria in patients diagnosed with AC.
METHODS: One hundred fifteen patients with AC were included in this retrospective study. Demographic characteristics of the patients and laboratory data were scanned from their hospital medical records. According to TG13/18 guidelines, the patients were divided into 3 groups as mild (grade 1), moderate (grade 2), and severe (grade 3) AC.
RESULTS: Sixty three (54.7%) of the patients were grade 1, 37 (32.1%) were grade 2, and 15 (13.0%) were grade 3. It was found that blood lactate level increased significantly from grade 1 to grade 3 (p < 0.001). In logistic regression analysis, white blood cell (WBC) count, total bilirubin and blood lactate levels independently determined the patients to be grade 2 or 3 AC. When the blood lactate cut-off value was taken as 16.5 mg/dL, we diagnosed grade 2 or 3 AC with a sensitivity of 78.8% and a specificity of 75.7%. From among lactate, WBC, and C reactive protein, lactate showed the highest value regarding the area under the curve, which is an index for predicting grade III upon ROC analysis.
CONCLUSION: The blood lactate level is associated with the severity of AC. In addition to TG13/18 guidelines, blood lactate level can be a useful biomarker in the severity grading of AC.
