Hepatic LDL receptor and vitamin D receptors are closely related to HCV infection. Aim: To assess the association between serum lipoproteins and vitamin D levels and sustained

viral response (SVR). Methods: 80 chronic HCV genotype 1 naïve patients (age 47±15 yrs; 43 men, BMI 28±3) received peg interferon alpha-2a (sc 180 µg once weekly) or peg interferon alpha 2b (1.5µg/kg) plus ribavirin 1200 mg/d during 48 weeks. Lipid profile and vitamin D levels were measured. HCV RNA was assessed by RT-PCR and undetectable HCV RNA at week 24 post treatment was considered as SVR. Patients were divided into two groups (responders Vs non responders according to SVR). Results: The patients population had a high BMI (28±2), high viral load (>400,000 IU/l) and high fibrosis score (Metavir scores >F2) in 50%, 40%, and 30% respectively. Overall, 42 % of patients were responders. Responders had significantly lower serum cholesterol levels (152±43 Vs 181±33 mg%, P=0.01), lower LDL levels (83±31 Vs 104±29, mg%, P=0.008), lower HDL levels (42±14 Vs 50±10, mg%, P=0.009), and higher vitamin D levels

(42.1±6.0 Vs 27.3±5.2 ng/ml, P< 0.001) than non responders. Triglycerides levels were similar in both groups (179±30 Vs 183±40, mg%, P>0.05). Multivariate logistic regression analysis showed that gender (Women, OR 2.3, P< 0.001), low cholesterol levels (< >180mg/dL; OR 2.5, P< 0.03), low HDL (< >40 mg/dL, OR 3.5, P< 0.001), and high vitamin D levels (< > 20 ng/ml, OR 3.8, P< 0.001) are strongly associated with SVR. Conclusions: Low HDL serum level and high vitamin D serum levels are strongly associated with sustained viral response in chronic HCV naïve genotype- 1 patients. http://www1.easl.eu/easl2011/program/Posters/Abstract1016.htm
