Compared to hepatitis A patients, patients with AHE presented with significantly lower median levels of alanine aminotransferase (ALAT) (798 U/L vs. 2326 U/L; p < 0.001) and median total serum bilirubin (1.8 mg/dL vs. 5.2 mg/dL; p < 0.001) than patients with AHA (Table 1, Figure 1a,b). This evidence concerns the gene GPT and autoimmune hemolytic anemia.
