HMGB1 and SEPP1 as predictors of hepatocellular carcinoma in patients with viral C hepatitis: Effect of DAAs.

BACKGROUND:Hepatitis C viral infection (HCV) and hepatocellular carcinoma (HCC) are potential health problems. New directly acting antivirals (DAAs) changed HCV treatment strategies. Selenoprotein P1 (SEPP1) is a hepatokine implicated in HCC pathogenesis. High mobility group box1 (HMGB1), a nuclear DNA-binding protein, involved in immune and inflammatory responses in HCV and HCC. Therefore, the aim of current study was to investigate HMGB1 and SEPP1 levels in HCV and HCV + HCC patients and exploring DAAs effect on them. METHODS:15 healthy volunteers, 25 HCV and 25 HCV + HCC patients were included. Liver function tests, alpha fetoprotein (AFP), SEPP1 and HMGB1 serum levels were evaluated. For HCV group blood samples before and after treatment with sofosbuvir/daclatasvir combination were collected. RESULTS:HMGB1 was significantly higher in HCV + HCC group than in control and HCV groups (p < .05). SEPP1 decreased significantly in HCV and HCV + HCC groups compared to control group (p < .001). SEPP1 significantly elevated after treatment with DAAs (p = .001). HMGB1 and SEPP1 were negatively correlated with each other in HCV group (p = .047). Logistic regression analysis showed that HMGB1 and SEPP1 could be used as predictors for HCC in HCV infected patients (p = .02,p = .002) respectively. Receiver operating characteristic curve (ROC) revealed HMGB1 had 32% sensitivity and 100% specificity in differentiating HCV from HCV + HCC patients, both SEPP1 and HMGB1 had high sensitivity (92%,60%) and 93% specificity in differentiating healthy from HCV + HCC group. CONCLUSION:HMGB1 and SEPP1 are involved in pathogenesis of HCV and HCV induced HCC. Both of them could serve as predictive biomarkers for HCC in HCV patients.
