Fecal calprotectin in patients with liver cirrhosis.
Indian Journal of Gastroenterology : Official Journal of the Indian Society of Gastroenterology 2023 October 13
BACKGROUND AND OBJECTIVES: Sepsis is the most challenging complication in patients with liver cirrhosis. It destabilizes patients leading to worsening of liver dysfunction and increased mortality. Intestinal bacterial dysbiosis, release of endotoxins, increased gut permeability and associated immune dysregulation have been described in cirrhotic patients with septic complications. Calprotectin is a major cytosolic protein secreted by the inflammatory cells and has been widely studied in patients with inflammatory bowel disease. We aimed at evaluating the role of fecal calprotectin (FCAL) in patients with liver cirrhosis.
METHODS: A prospective, observational study on the utility of FCAL test was conducted in patients with liver cirrhosis. Fifteen milligrams of fecal specimen was collected and analyzed within 48 hours of hospitalization from patients with end-stage liver disease (ESLD), acute-on-chronic liver failure (ACLF) and at the time of outpatient visit for stable cirrhotics. Five healthy volunteers underwent FCAL test as control population.
RESULTS: The mean FCAL (µg/g) level in healthy control (n = 5), stable cirrhotics (n = 10), ESLD (n = 10) and ACLF (n = 10) patients was 109.2 (95% CI: - 53.39 to 271.79), 143.3 (95% CI: 50.5-236.45), 176.9 (95% CI: 122.93-230.87) and 543.5 (95% CI: 207.09-879.91) (p = 0.005), respectively. Sepsis was identified in 13 (43.3%) patients. Area under the receiver-operating characteristics curve (AUROC) of FCAL was 0.80 (p = 0.005) and FCAL ≥ 200 µg/g (OR = 10.8, p = 0.006) was associated with sepsis. Nine (25.7%) patients expired. FCAL level was significantly higher in dead patients compared to survivors (mean, 493.67 (95% CI: 142.20-845.14) vs. 199.71 (95% CI: 99.84-299.59) μg/g,p = 0.005.
CONCLUSIONS: FCAL levels are increased in patients with chronic liver disease, with highest level in ACLF. An FCAL level of ≥ 200 µg/g was associated with sepsis and mortality in cirrhotic patients. Larger studies are required to identify the role of FCAL in these patients. Early identification and initiation of anti-microbials may mitigate sepsis and reduce mortality.
