A novel program for treating patients with trimorbidity: hepatitis C, serious mental illness, and active substance use.
ABSTRACT BACKGROUND: Advances in hepatitis C virus (HCV) treatment have yielded improved virological response rates, and yet, many individuals with psychiatric illness still fail to receive HCV therapy. Concerns about safety, adherence, and efficacy of HCV treatment are compounded and treatment is further deferred when substance use is also present. This is especially problematic given the disproportionately high rates of both mental health issues and substance use among individuals living with HCV. OBJECTIVE: This study sought to examine HCV treatment outcomes in clients with serious mental illness (SMI) and with high rates of active substance use who were participating in a community-based HCV treatment program. PATIENTS AND METHODS: A retrospective chart review of 129 clients was carried out. Patients were classified as having an SMI if they had a history of bipolar disorder, psychotic disorder, past suicide attempt or mental health related hospitalization. RESULTS: Fifty-one patients were defined as having an SMI. Among the 46 patients with SMI and a detectable HCV viral load, HCV antiviral therapy was initiated in nine (19.6%). A relapse or an increase in substance use was common (77.8% or n=7), as was the requirement for adjustment or initiation of psychotropic medications (66.7% or n=6) during HCV antiviral therapy. Despite these barriers, rates of adherence to antiviral therapy were high and overall sustained virological response rates were comparable with published trials. CONCLUSION: This study is the first to report HCV treatment outcomes in a population in which SMI and active polysubstance use was prevalent and suggests that with appropriate models of care, clients with trimorbidity can be treated safely and effectively.

ABSTRACT: BACKGROUND: Despite recent advances in hepatitis C (HCV) treatment, speci fically the addition of direct acting antivirals (DAAs), pegylated interferon-alpha remains the backbone of HCV therapy. Therefore, the impact of DAAs on the management of co-morbid psychi atric illness and neuropsychiatric sequalae remains an ongoing concern during HCV therapy. This paper provides a review of the neuropsychiatric adverse effects of DAAs and drug-drug interactions (DDIs) between DAAs and psychiatric medications. METHODS: We conducted a Pubmed search using relevant search terms and hand searched reference lists of related review articles. In addition, we searched abstracts for major hepatology conferences and contacted respective pharmaceutical companies for additional studies. RESULTS: Limited data is available on the neuropsychiatric adverse effects of DAAs; however, data from major clinical trials suggest that DAAs have minimal neuropsychiatric risk. DAAs can potentially interact with a variety of psychotropic agents via cytochrome P450 and p-glycoprotein interactions. Triazolam, oral midazolam, St. John's Wort, carbamazepine and pimozide, are contraindicated with DAAs. DDIs between DAAs and antidepressants, anxiolytics, hypnotics, mood stabilizers, antipsychotics and treatments for opioid dependence are summarized. CONCLUSIONS: Although DAAs do not add significant neuropsychiatric risk, the potential for DDIs is high. Consideration of DDIs is paramount to improving medication adherence and mitigating adverse effects during HCV therapy.BMC Gastroenterology 05/2013; 13(1):86. · 2.11 Impact Factor
