Chronic hepatitis C virus (HCV) infection is a major global health problem affecting 3-5 million people in the United States and over 100 million worldwide. Chronic HCV infection, which can lead to cirrhosis and hepatocellular carcinoma, also results in numerous other complications, including impairment of renal function. Because HCV is most often transmitted via parenteral exposure to blood or blood products, patients with end-stage renal disease (ESRD) treated with hemodialysis are at particular risk for infection. Historically, the medications available to treat HCV infection in these patients had significant side effects and were not particularly effective in generating a sustained virologic response. Since 2011, a number of direct-acting antiviral therapies have emerged that can lead to virological cure in the vast majority of patients, with low pill burden and few side effects. Here, we describe the biology and pathophysiology of HCV infection, and summarize current information on new therapies, with a particular focus on their application in patients with chronic kidney disease including ESRD.

Patients with end-stage renal disease treated with dialysis are often prescribed complex medication regimens, placing them at risk for drug-drug interactions and other medication-related problems. Particularly in the context of a broader interest in more patient-centered value-based care, improving medication management is an increasingly important focus area. However, current medication management metrics, designed for the broader patient population, may not be well suited to the specific needs of patients with kidney disease, especially given the complexity of medication regimens used by dialysis patients. We propose a kidney pharmacy-focused quality pyramid that is intended to provide a framework to guide dialysis organizations, health care providers, and/or clinicians with respect to an optimal medication management approach for dialysis patients. Incorporation of core programs in medication management, including medication reconciliation, safety programs, and medication therapy management for patients at high risk for medication-related problems, may result in improved outcomes. Although a growing body of evidence supports the concept that active medication management can improve medication adherence and reduce medication-related problems, these strategies are viewed as costly and are not widely deployed. However, if done effectively, pharmacy-led medication management has the potential to be one of the more cost-effective disease management strategies and may greatly improve outcomes for these complex patients.
