P-37 EXPERIENCE IN MEXICO WITH DIRECT ACTING ANTIVIRALS AS A TREATMENT FOR HEPATITIS C

Abstract

Background: It is considered that globally, 71 million people have chronic infection caused by the virus of Hepatitis C (HCV). It is estimated that in 2016 approximately 399,000 people died due to it. Among the infected people 70% develop a chronic infection caused by HCV. In Mexico, it was reported that 6% of them is type C, and the most common genotype is 1. Interferon and ribavirin, hardly ever used in developed countries, are still recommended in Mexico for treating this infection. Aim: To assess the effectiveness of direct acting antivirals (DAA) in Mexican population with HC. Methods: In a retrospective, multicenter study in 20 hospitals in Mexico, information of patients with HC and treated with DAA was gathered. Results: A total of 913 patients were included. The gender distribution was 599 women and 314 men, the mean age was 58.88 ± 12.10 years old. The most frequent genotype was genotype 1. It was found that there is 99% of sustained viral response in genotype 1. Presented side effects were slight. Conclusion: We found a very high SVR rate, 99%, which is why applying DAA immediately after a patient is diagnosed with Hepatitis C to avoid further complications is recommended.Core tip: In Mexico, a large sample of patients was documented, where it was concluded that DAA should be used without the fear of adverse events, and to be certain about an SVR to the most frequent genotype in our population. However, the use of pangenomic DAA must be considered.
