Direct acting antivirals for the treatment of hepatitis C in ethnic minority populations.

INTRODUCTION: Direct acting antivirals (DAA's) have revolutionized the treatment of hepatitis C (HCV). However, questions persist concerning their efficacy in minority populations. AREAS COVERED: In this review, the authors review outcomes for treatment of HCV by race and ethnicity among the clinical trials that have led to the current recommended treatments for HCV. The authors highlight the efficacy and safety differences by race and ethnicity. They also highlight deficiencies within the literature including small populations of racial/ethnic minorities within HCV clinical trials. DAA's can achieve cure rates for HCV over 95% with the use of once daily medications that have minimal side effects and few significant drug-drug interactions. Regimens with high pan-genotypic efficacy have further simplified treatment paradigms. The purpose of this review is to describe the data on DAA's in treating HCV in racial/ethnic populations. EXPERT OPINION: While the overall data in racial/ethnic minority populations is sparse, DAA's appear to have high efficacy in curing HCV in diverse racial/ethnic populations. Although achieving high sustained virologic response (SVR) rates, there are also data that suggests that some disparities in SVR persist, especially when considering shorter regimens for HCV treatment in racial/ethnic populations.
