Alpha-fetoprotein as a prognostic marker in acute liver failure: a pilot study

Area of Science:

• Hepatology
• Biochemistry
• Clinical Medicine

Background:

• Prognostic markers for acute liver failure (ALF) typically rely on clinical, radiological, or hepatic degeneration-based biochemical parameters.
• There is a need for reliable markers that reflect liver regeneration capacity in ALF patients.

Purpose of the Study:

• To investigate the impact of serial serum alpha-fetoprotein (AFP) levels, a marker of liver regeneration, on patient outcomes in ALF.
• To determine if AFP dynamics can serve as a prognostic indicator in ALF.

Main Methods:

• Serum AFP levels were measured on days 1 and 3 of hospitalization in 32 ALF patients.
• The ratio of AFP levels (day 3/day 1) was calculated and correlated with patient survival outcomes.
• Patients were categorized into expired (Group A) and survived (Group B) groups.

Main Results:

• The AFP ratio was significantly lower in the expired group (0.84 ± 0.15) compared to the survived group (1.55 ± 0.70) (P < 0.001).
• Initial absolute AFP values did not correlate with patient outcomes.
• Dynamic changes in AFP levels demonstrated prognostic value.

Conclusions:

• Alpha-fetoprotein levels change dynamically during ALF and are a significant predictor of patient outcomes.
• Serial AFP measurements, particularly the day 3/day 1 ratio, show potential as a prognostic marker for ALF, alone or with existing markers.
