Title: Prevalence and predictive factors of moderate/severe liver steatosis in chronic hepatitis C (CHC) infected patients evaluated with controlled attenuation parameter (CAP).
Abstract: A novel controlled attenuation parameter (CAP) using FibroScan&#174; has been developed for assessment of liver steatosis. The aim was to evaluate the frequency and associated factors for moderate/severe steatosis evaluated by CAP in CHC patients submitted to transient elastography (TE) by FibroScan&#174; . CHC patients underwent TE with CAP evaluation. The classification of steatosis was defined as: CAP < 222 dB/m&#160; = &#160;S0; CAP &#8805; 222 dB/m and <233dB/m&#160; = &#160;S1; &#8805;233 dB/m&#160;<&#160;290dB/m&#160; = &#160;S2 and >= 290 dB/m&#160; = &#160;S3. The prevalence of moderate/severe steatosis (CAP &#8805; S2) and the related independent factors were identified by a logistic regression analysis. A significance level of 5% was adopted. 1104 CHC patients, 85% genotype-1 were included (mean age 55&#160;&#177;&#160;11&#160;years; 46% male, mean BMI 25&#160;&#177;&#160;4 Kg/m2 ). Systemic arterial hypertension and type 2 diabetes mellitus prevalences were 39% and 17%, respectively. Liver stiffness measurement &#8805; 9.5 kPa was observed in 39% of patients and steatosis was identified in 50% (S1&#160;=&#160;7%, S2&#160;=&#160;28% and S3&#160;=&#160;15%). The variables independently associated with moderate/severe steatosis were: male gender (OR=1.35; P&#160;=&#160;.037; 95% CI:1.01-1.81); systemic arterial hypertension (OR=1.57; P&#160;=&#160;.002; 95% CI:1.17-2.10) and BMI (OR=1.17; P&#160;<&#160;.01;95% CI:1.12-1.22). In conclusion, when CAP was adopted as a tool to detect steatosis, genotype 1 CHC patients presented a high prevalence of moderate/advanced steatosis. In these patients, liver steatosis was associated mostly to metabolic factors (arterial hypertension and high BMI).
