How do we measure successful hepatitis C (HCV) treatment? Is it strictly by clinical trial data showing how safe and effective a treatment is? Alternatively, is it by patients’ experiences, outcomes, and overall quality of life? This ambitious study examined patients’ experiences of living with hepatitis C and its treatment.
They found that current data support the fact that HCV patients suffer substantially. This burden was much worse during interferon/ribavirin treatment and worse yet if that treatment used telaprevir or boceprevir. The newer interferon-free treatments showed that patients reported improvements in quality of life and productivity; and even bigger improvements with ribavirin-free regimens. Patients who reported easier treatment were more likely to complete therapy and respond to it.
This study also looked at fibrosis stage, finding significant fatigue and impairment among those with early stage liver disease. Patients with early fibrosis reported significant benefits, similar to the gains achieved by those with advanced fibrosis.
The Bottom Line: Using fibrosis stage to limit the cost of HCV treatment does not take in to account the other costs of HCV, such as its effect on work productivity, quality of life, etc.
Editorial Comment: This study validates what patients have been reporting for decades—that having hepatitis C is hard, and that the newer treatments offer hope for improved quality of life. Denying access to treatment violates human rights.

After an HCV exposure, about half of those exposed will form antibodies in 5 to 10 weeks.
It averages 10 to 13 weeks for HCV antibodies to be detectable in HCV/HIV-coinfected men who have sex with men (MSM). There have been reports of some HIV-infected individuals for whom HCV antibodies didn’t show up for more than 3 years. In this case study, an HIV-positive man had positive HCV viral load results for 7 years but never had a positive HCV-antibody test result.
The Bottom Line: These researchers recommend HCV viral load testing rather than relying solely on antibody testing for HIV-infected MSM.
Editorial Comment: I am both fascinated and irritated when there are rare exceptions in medical science, but they do exist.
Article: Hepatitis C Virus Infection: A Risk Factor for Parkinson’s Disease – Wendy Wu, et al.

Recent evidence indicates that HCV may invade the central nervous system. In rat studies, researchers observed that HCV and Parkinson’s disease both overexpress inflammatory biomarkers. Analyzing data from 62,276 subjects, researchers found similarities between HCV and Parkinson’s.
The Bottom Line: This study demonstrated an association between HCV infection and Parkinson’s and confirms the observation of dopaminergic toxicity of HCV similar to that found in rats.
Editorial Comment: As horrifying as these results are, perhaps this research will shed light on the nature of “brain fog,” which is experienced by so many HCV patients.
Article: Hepatitis A hospitalizations in the United States, 2002-2011 – Melissa Collier, et al.
Source: Hepatology February 2015
This study reviewed hospitalization rates for hepatitis A from 2002-2011. The number of hepatitis A-related hospitalizations hasdeclined significantly, but patients who are hospitalized for hepatitis A are older and more likely to have liver diseases and other comorbid medical conditions.
The Bottom Line: Immunization could prevent hepatitis A infection and ensuing hospitalizations.
Editorial Comment: Hepatitis A vaccination is recommended for hepatitis C patients.
