Prevalence of Hepatitis C and Fibrosis Stage per Age Group in Lebanese Population

In Lebanon, hepatitis C virus (HCV) prevalence is estimated to 0.2% among all ages, with genotype 1 the most common genotype. The age distribution shows 2 peaks reflecting 2 probable mode of transmission of HCV in Lebanon: 20-39 years and more than 40 years. The burden of HCV-related complications on the health system in Lebanon is expected to increase in the upcoming years. The number and prevalence per age group and the fibrosis stage of HCV infections is required to better estimate the burden of the disease in Lebanon. We calculated the prevalence per age group. Concerning fibrosis stage, patients recently diagnosed with HCV and never been treated previously were included and were divided into three groups according to their age Concerning the prevalence by age group, the lowest was seen in the group less than 20 years and the highest in the population aged more than 60. Concerning the fibrosis by age group, the majority of patients less than 40 years had low fibrosis stage, while in the group of more than 60 years F3 and F4 represent respectively 15.07% and 68.49%. Female gender had more significant fibrosis and cirrhosis than male gender. There is an exponential increase of significant fibrosis with age In Lebanon, the highest prevalence of hepatitis C is seen in the age group more than 60 years. In the 2 age groups (40-59 years and >60 years), we noted an advanced fibrosis stage and the majority of patient more than 60 years were cirrhotic at the time of diagnosis, which can reflect the burden of the disease in these groups.
