PURPOSE: We previously reported that measuring serum telomerase reverse transcriptase (hTERT) mRNA with a quantitative, one-step, real-time RT-PCR was superior to conventional tumor markers for hepatocellular carcinoma and lung cancer. Here, we examined serum regeneration-related mRNA detection as a biomarker for fulminant hepatitis (FH). METHODS: In 53 patients, including 17 patients with acute hepatitis (AH), seven with severe hepatitis (SH), four with late-onset hepatic failure (LOHF), and 25 with FH, we measured serum mRNA levels of hTERT, hepatocyte growth factor (HGF), hepatocyte growth factor receptor (c-met), epidermal growth factor receptor (EGFR), and transforming growth factor-alpha (TGF-alpha). We examined the sensitivity and specificity of the technique in FH diagnosis as well as its clinical and prognostic significance compared with other clinical and prognostic tests. RESULTS: Serum copy number of TGF-alpha mRNA in FH on admission was significantly smaller than in AH and SH. In FH, TGF-alpha mRNA level was 10(6)-fold higher in survivors than in patients who died or received liver transplants (P = 0.034), although these patients were not discriminated by other clinical parameters. The sensitivity/specificity for prognosis in FH was 74.3/65.5% for TGF-alpha mRNA. Of four prognostic scoring systems, only logit-lambda was useful for prognosis assessment. CONCLUSIONS: TGF-alpha mRNA is an early predictor of FH outcome and a sensitive biomarker of lower regenerative liver capacity. This assay could help facilitate early therapy choice, such as liver transplantation.
