Effectiveness of Direct-Acting Antiviral Therapy in Patients With Human Immunodeficiency Virus-Hepatitis C Virus Coinfection in Routine Clinical Care: A Multicenter Study.

ABSTRACT:

Background

Direct-acting antiviral (DAA) therapy have been shown to be highly successful in clinical trials and observational studies, but less is known about treatment success in patients with a high burden of comorbid conditions, including mental health and substance use disorders. We evaluated DAA effectiveness across a broad spectrum of patients with human immunodeficiency virus (HIV)-hepatitis C virus (HCV) coinfection in routine clinical care, including those with psychosocial comorbid conditions.

Methods

The primary end point was sustained virologic response (SVR), defined as HCV RNA not detected or <25 IU/mL ?10 weeks after treatment. We calculated SVR rates and 95% confidence intervals (CIs) in a modified intent-to-treat analysis. We repeated this analysis after multiply imputing missing SVR values.

Results

Among 642 DAA-treated patients, 536 had SVR assessments. The median age was 55 years; 79% were men, 59% black, and 32% white. Cirrhosis (fibrosis-4 index>3.25) was present in 24%, and 17% were interferon treatment experienced; 96% had genotype 1 infection and 432 (81%) had received ledipasvir-sofosbuvir. SVR occurred in 96.5% (95% CI, 94.5%-97.9%). Patients who were black, treatment experienced, or cirrhotic all had SVR rates >95%. Patients with depression and/or anxiety, psychotic disorder, illicit drug use, or alcohol use disorder also had high SVR rates, ranging from 95.4% to 96.8%. The only factor associated with lower SVR rate was early discontinuation (77.8%; 95% CI, 52.4%-93.6%). Similar results were seen in multiply imputed data sets.

Conclusions

Our study represents a large multicenter examination of DAA therapy in HIV/HCV-coinfected patients. The broad treatment success we observed across this diverse group of patients with significant comorbid conditions is highly affirming and argues for widespread implementation of DAA therapy.

Project description:We evaluated treatment outcomes in a prospective registry of human immunodeficiency virus/hepatitis C virus (HCV)-coinfected patients treated with interferon-free direct-acting antiviral agent-based therapy in hospitals from the region of Madrid between November 2014 and August 2016. We assessed sustained viral response at 12 weeks after completion of treatment and used multivariable logistic regression to identify predictors of treatment failure. We evaluated 2,369 patients, of whom 59.5% did not have cirrhosis, 33.9% had compensated cirrhosis, and 6.6% had decompensated cirrhosis. The predominant HCV genotypes were 1a (40.9%), 4 (22.4%), 1b (15.1%), and 3 (15.0%). Treatment regimens included sofosbuvir (SOF)/ledipasvir (61.9%), SOF plus daclatasvir (14.6%), dasabuvir plus ombitasvir/paritaprevir/ritonavir (13.2%), and other regimens (10.3%). Ribavirin was used in 30.6% of patients. Less than 1% of patients discontinued therapy owing to adverse events. The frequency of sustained viral response by intention-to-treat analysis was 92.0% (95% confidence interval, 90.9%-93.1%) overall, 93.8% (92.4%-95.0%) for no cirrhosis, 91.0% (88.8%-92.9%) for compensated cirrhosis, and 80.8% (73.7%-86.6%) for decompensated cirrhosis. The factors associated with treatment failure were male sex (adjusted odds ratio, 1.75; 95% confidence interval, 1.14-2.69), Centers for Diseases Control and Prevention category C (adjusted odds ratio, 1.65; 95% confidence interval, 1.12-2.41), a baseline cluster of differentiation 4-positive (CD4+) T-cell count <200/mm3 (adjusted odds ratio, 2.30; 95% confidence interval, 1.35-3.92), an HCV RNA load ≥800,000 IU/mL (adjusted odds ratio, 1.63; 95% confidence interval, 1.14-2.36), compensated cirrhosis (adjusted odds ratio, 1.35; 95% confidence interval, 0.96-1.89), decompensated cirrhosis (adjusted odds ratio, 2.92; 95% confidence interval, 1.76-4.87), and the use of SOF plus simeprevir, SOF plus ribavirin, and simeprevir plus daclatasvir.ConclusionIn this large real-world study, direct-acting antiviral agent-based therapy was safe and highly effective in coinfected patients; predictors of failure included gender, human immunodeficiency virus-related immunosuppression, HCV RNA load, severity of liver disease, and the use of suboptimal direct-acting antiviral agent-based regimens.

Project description:Patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) have higher levels of immune activation, impaired antigen-specific responses, and accelerated fibrogenesis compared to patients monoinfected with HCV. Whether different direct-acting antiviral (DAA) combinations have differential effects on immunophenotypes and functions following successful HCV therapy remain unknown. Therefore, we aimed to assess the peripheral T-cell immunophenotypes and functions in patients coinfected with HIV/HCV who were successfully treated with combination DAA treatment regimens. We analyzed peripheral blood mononuclear cells (PBMCs) at baseline and at the time of sustained viral response (SVR) from subjects treated with three different combination DAA regimens: daclatasvir (DCV) and asunaprevir (ASV) for 24 weeks (CONQUER 2-DAA), DCV/ASV/beclabuvir (BCV) for 12 weeks (CONQUER 3-DAA), and sofosbuvir (SOF) and ledipasvir (LDV) for 12 weeks (ERADICATE study). We used flow cytometry to assess T-cell phenotypes (activation and exhaustion) and HCV-specific T-cell functions (cytokine secretion and cytotoxicity). Statistical analyses were conducted using the Wilcoxon matched-pairs signed-rank test with P < 0.05 considered significant. Overall, there was an improvement in T-cell exhaustion markers, a decrease in T-cell activation, an increase in the effector memory population, and improved T-cell function after achieving SVR, with the largest effects noted with CONQUER 3-DAA treatment. Conclusion: Treatment with DCV/ASV/BCV in patients coinfected with HIV/HCV resulted in greater restoration of the T-cell impairments and perturbations associated with HIV/HCV coinfection to an extent that was greater than that observed in either two-drug regimens. We showed that different DAA-based therapies have different immunologic outcomes after successful HCV treatment in patients coinfected with HIV/HCV. This information will be beneficial for providers when selecting the regimens for patients coinfected with HIV/HCV.
