Ferritin as a Prognostic Marker for Mortality and Critical Inpatient Outcomes in the Alcohol Related Hepatitis Population
Background: Alcoholic hepatitis (AH) is a severe inflammatory liver disorder with mortality rates of 20–50% at 90 days. Ferritin is an acute-phase reactant elevated in AH due to hepatocellular injury, systemic inflammation, and altered iron homeostasis. Its prognostic significance in AH has not been fully elucidated. To evaluate the association between serum ferritin levels and short-term clinical outcomes in patients with alcoholic hepatitis.
Methods: This retrospective cohort study utilized the TriNetX US Collaborative Network. Patients with AH (ICD-10: K70.1, K70.10, K70.11) and documented serum ferritin were included. Patients with autoimmune hepatitis, viral hepatitis, hemochromatosis, Wilson disease, and primary biliary or sclerosing cholangitis were excluded. Patients were stratified into low-ferritin (1,000 ng/mL) and high-ferritin (≥1,000 ng/mL) cohorts. The primary outcome was all-cause mortality within 90 days. Secondary outcomes included hepatic failure, sepsis, shock, ascites, spontaneous bacterial peritonitis (SBP), esophageal variceal bleeding, and hepatic encephalopathy.
Results: Of 73,476 patients, 58,815 had ferritin 1,000 ng/mL, and 14,661 had ferritin ≥1,000 ng/mL. Patients with elevated ferritin had significantly higher 90-day mortality (20.0% vs. 8.7%; HR 2.66, p 0.001). Elevated ferritin was also associated with increased risks of hepatic failure (HR 1.55), sepsis (HR 1.85), shock (HR 1.94), ascites (HR 1.17), SBP (HR 1.52), and hepatic encephalopathy (HR 1.32) (all p 0.001). Esophageal variceal bleeding was less frequent in the high-ferritin cohort (HR 0.73, p 0.001).
Conclusion: Serum ferritin ≥1,000 ng/mL is associated with significantly worse 90-day outcomes in AH. Ferritin represents a simple, inexpensive biomarker that may aid in prognostic assessment and risk stratification. Prospective studies with multivariable adjustment are warranted.
