Insights
Direct-acting antivirals (DAA) offer effective hepatitis C virus (HCV) treatment. This review examines management for "special populations" with HCV, including those with cirrhosis or kidney disease, to ensure treatment success.
Area of Science:
- Hepatology
- Infectious Diseases
- Pharmacology
Background:
- Direct-acting antivirals (DAA) have transformed hepatitis C virus (HCV) treatment, aligning with WHO goals for HCV elimination by 2030.
- Certain patient groups, termed "special populations," present challenges in achieving sustained virological response (SVR) due to comorbidities, drug interactions, or prior treatment failures.
- The definition and clinical relevance of these "special populations" require clarification years after DAA introduction.
Purpose of the Study:
- To critically review and analyze current evidence regarding the management and treatment of "unique" or "special" patient populations with HCV.
- To provide an updated overview of the challenges and unmet needs in treating these specific patient groups.
Main Methods:
- Literature review focusing on direct-acting antiviral (DAA) therapy in hepatitis C virus (HCV) patients.
- Emphasis on specific subgroups: decompensated cirrhosis, chronic kidney disease (CKD), coinfections (e.g., HIV, HBV), rare HCV genotypes, and patients with prior treatment failure.
- Analysis of efficacy, safety, and management strategies for these challenging populations.
Main Results:
- DAAs demonstrate high efficacy and safety across most patient groups, yet SVR rates can be lower in specific populations.
- Decompensated cirrhosis, advanced CKD, and certain coinfections necessitate tailored treatment regimens and careful monitoring.
- Previous DAA treatment failure or rare genotypes may require alternative therapeutic approaches.
Conclusions:
- The concept of "special populations" in HCV treatment remains relevant, requiring individualized management strategies.
- Further research is needed to optimize DAA therapy for patients with complex comorbidities and unique virological profiles.
- Addressing the needs of these difficult-to-treat groups is crucial for achieving global HCV elimination goals.
Abstract:
Direct-acting antivirals (DAA) have revolutionized the treatment of patients with chronic hepatitis C virus (HCV) infection, possibly leading to HCV elimination by 2030 as endorsed by the World Health Organization (WHO). However, some patients belonging to the so-called unique or special populations are referred to as difficult-to-treat due to unreached sustained virological response, potential drug side effects or interactions or co-morbidities. Several years after the DAA introduction and on the basis of excellent findings in terms of efficacy and safety, some doubts arise around the exact meaning of the special population designation and whether this group of patients actually exists. The aim of this review is to discuss and analyze current evidence on the management and treatment of the so-called "unique populations". We placed particular emphasis on patients with decompensated cirrhosis, chronic kidney disease (CKD), coinfections, rare genotypes, and previous treatment failure, in order to provide physicians with an updated overview of the actual problems and needs in the current scenario.
