Insights
Patient adherence to Hepatitis C Virus (HCV) treatments like interferon and ribavirin varied significantly and decreased over time. Key non-adherence factors included prescription delays, financial issues, and side effects.
Area of Science:
- Hepatology
- Infectious Diseases
- Pharmacology
Background:
- Hepatitis C Virus (HCV) treatment adherence, its influencing factors, and impact on patient outcomes remain under-researched.
- Understanding adherence is crucial for optimizing treatment efficacy in HCV patients.
Purpose of the Study:
- To evaluate patient adherence to anti-HCV medications within the Iranian population.
- To identify factors affecting adherence and its correlation with treatment outcomes.
Main Methods:
- A cohort of 190 HCV patients was studied from October 2010 to March 2011.
- Adherence was assessed using self-reporting and pill counting at 1, 3, and 6 months, adhering to the 80/80/80 rule.
- Socio-demographic, clinical, and HCV infection characteristics were collected.
Main Results:
- Adherence rates for interferon, ribavirin, or combination therapy ranged from 28.4% to 65.8% over 6 months.
- Common reasons for non-adherence included delayed prescriptions, financial difficulties, and adverse drug reactions.
- Adherence to ribavirin independently predicted treatment and sustained virological response.
Conclusions:
- Adherence rates to interferon and ribavirin treatments varied based on measurement methods.
- A significant decline in adherence to interferon alpha and ribavirin was observed throughout the treatment duration.
Background:
Various aspects of adherence to HCV treatment such as frequency, risk factors as well as causes of non-adherence, and its real role in clinical and virological outcome of the infected patients have remained largely unknown.
Objectives:
The current study aimed to evaluate patients' adherence to anti-HCV medications in Iran.
Materials And Methods:
From October 2010 to March 2011, socio-demographic characteristics, features of HCV infection, clinical properties, and habitual history of 190 patients were collected. Adherence of each patient to anti-HCV medications was determined at months 1, 3, and 6 of treatment by self-reporting and pill or empty ampoule counting. Adherence to anti-HCV treatment regimen was determined based on the 80/80/80 rule.
Results:
Adherence rate to interferon, ribavirin, or a combination of them over the first 6 months of therapy in Iranian HCV patients measured by both methods of self-reporting and pill counting were 35.4-65.8%, 46.3-56.8%, and 28.4-51.1%, respectively. Delay in receiving new prescription, financial issues, and adverse drug reactions were the most common causes of non-adherence in the patients. Adherence to ribavirin was identified as an independent predictor of achieving the end of treatment response, or sustained virological response.
Conclusions:
The rate of adherence to interferon and ribavirin varied significantly according to the method of calculation. Over the treatment course, adherence to interferon alpha and ribavirin, each or their combination, diminished significantly.
