    Abstract:
    AIM: To assess the diagnostic value of Fibrotest in comparison with liver biopsy, for the evaluation of hepatic fibrosis in patients with chronic hepatitis C. METHODS: This prospective study included in 2 years (2006-2007), consecutive patients with chronic hepatitis C naive to treatment. Fibrotest and liver biopsy were performed. Receiver operating characteristics (ROC) curves , the sensitivity, specificity, positive and negative predictive values were used to assess the diagnostic value of Fibrotest in comparison with the METAVIR classification. RESULTS: We recruited a total of 65 patients: 28 males and 37 females (mean age: 50 years); 92% of the patients had genotype 1. The histological fibrosis results were: 3.1% F0; 24.6% F1; 32.3% F2; 29.2% F3 and 10.8 % F4. The diagnostic value of Fibrotest in the detection of significant fibrosis (F2-F4) was 0. 87. A score > 0.5 has a sensitivity of 85. 1%, a specificity of 72. 2%, a positive predictive value of 88. 9%,and a negative predictive value of 65%. The diagnostic value of Fibrotest in the detection of cirrhosis (F4) was 0. 85. There were 13/65 cases of discordance (20%) for fibrosis, 4 cases were attributable to biopsy and 6 cases to Fibrotest. The discordance was unexplained in 3 cases. the size of biopsy< 15 mm [OR=2. 82, 95% CI, 1. 3-6. 07; p = 0. 008] and the stage of fibrosis F0, F1, F2 [OR =3. 35 , 95% CI, 1. 1-10. 2; p=0. 03] were considered as risk factors of discordance in multivariate analysis. CONCLUSION: This prospective study confirmed the good diagnostic value of Fibrotest as compared with the histological analysis of liver biopsy.
