Barriers to Treating HCV in HIV-coinfected Patients

By Brian Boyle, MD

Overcoming the barriers that stand in the way of providing medical care to those who need it can sometimes be difficult. This difficulty is reflected in a study from Johns Hopkins, one of the premier centers for the treatment of HIV and hepatitis in the US.

The study evaluated predictors and trends of referral for hepatitis C virus (HCV) care, clinic attendance, and treatment uptake in the Johns Hopkins HIV clinic, which provides care for >3000 HIV-infected persons of whom ~50% are HCV-co-infected.

In 1998, an on-site viral hepatitis clinic was opened; however, while between 1998-2003 845 HIV/HCV-co-infected adults regularly attended the HIV clinic, few ended up getting on HCV treatment and only 6 – or 0.7% of the eligible population – achieved a sustained virologic success.

How did such a prestigious center end up with such disastrous results? The problems begin with referral and patient attendance at appointments. Of the 845 HIV/HCV patients eligible for treatment, 277 (33%) were referred for care and 185 (67%) kept their appointment.

Independent predictors of referral and attendance (p <0.05) were markers of liver disease including percentage elevated alanine aminotransferase (ALT) levels, markers of controlled HIV including undetectable HIV RNA, CD4 >350 cells/mL and use of ART, and being in psychiatric care.

Further, in a subsample participating in confidential surveys, patient illicit drug use was a barrier to referral and attendance. Of 185 who entered care, 32% failed to complete a pre-treatment medical evaluation. Of the remaining 125, 44(35%) were ineligible for treatment:  19 had end-stage liver disease, 9 were HCV RNA negative, and 16 had AIDS/<2-year life expectancy.

Of the 81 eligible, 47% had mild fibrosis (F1-2) and 23% had cirrhosis (F5-6) on biopsy and 29 (36%) initiated HCV treatment of whom 6 (21% of the treated population) achieved sustained virologic response. Reasons for not treating were mild liver disease (58%), psychiatric illness (12%), alcohol/drug use (12%), and patient refusal (15%). 

The authors note that referrals increased in 2003, but that more than one-half of patients with a CD4>350 still are not being referred. The authors conclude, “Substantial barriers at the provider-level (non-referral of some patients with high CD4) and the individual (active drug use) still exist even when cost and access are not issues. A case management-based approach to HCV care may improve treatment uptake and diminish losses to follow-up in this population.”
