Real-world evidence of the effectiveness of ombitasvir-paritaprevir/r ± dasabuvir ± ribavirin in patients monoinfected with chronic hepatitis C or coinfected with human immunodeficiency virus-1 in Spain.

Aim: We describe the effectiveness and safety of the interferon-free regimen ombitasvir/paritaprevir/ritonavir plus dasabuvir with or without ribavirin (OBV/PTV/r ± DSV ± RBV) in a nationwide representative sample of the hepatitis C virus (HCV) monoinfected and human immunodeficiency virus-1/hepatitis C virus (HIV/HCV) coinfected population in Spain.

Material And Methods: Data were collected from patients infected with HCV genotypes 1 or 4, with or without HIV-1 coinfection, treated with OBV/PTV/r ± DSV ± RBV at 61 Spanish sites within the initial implementation year of the first government-driven "National HCV plan." Effectiveness was assessed by sustained virologic response at post-treatment week 12 (SVR12) and compared between monoinfected and coinfected patients using a non-inferiority margin of 5% and a 90% confidence interval (CI).

Evaluation of the Innate Immune Modulator Acitretin as a Strategy To Clear the HIV Reservoir.

The persistence of HIV despite suppressive antiretroviral therapy is a major roadblock to HIV eradication. Current strategies focused on inducing the expression of latent HIV fail to clear the persistent reservoir, prompting the development of new approaches for killing HIV-positive cells. Recently, acitretin was proposed as a pharmacological enhancer of the innate cellular defense network that led to virus reactivation and preferential death of infected cells.

Optimal Use of Transient Elastography and Acoustic Radiation Force Impulse to Stage Liver Fibrosis in HIV/HCV-Coinfected Patients in Clinical Practice.

Objectives: Liver fibrosis (LF) is crucial for the individualized management of patients with hepatitis C virus (HCV). We evaluated the concordance between two noninvasive methods for staging LF, transient elastography (TE) and acoustic radiation force impulse (ARFI), in patients coinfected with human immunodeficiency virus and HCV. We propose an algorithm for optimal use of both techniques in routine clinical practice.

Short-term Treatment With Interferon Alfa Diminishes Expression of HIV-1 and Reduces CD4+ T-Cell Activation in Patients Coinfected With HIV and Hepatitis C Virus and Receiving Antiretroviral Therapy.

Long-term treatment with interferon (IFN) alfa plus ribavirin decreases the proviral human immunodeficiency virus type 1 (HIV) DNA level. However, the short-term impact of IFN alfa on persistent HIV and its effects on immune activation after antiretroviral therapy remain unknown. Our study showed that the cell-associated HIV RNA level and CD4(+) T-cell activation decreased in the IFN group (n = 10).

Prevalence and factors associated with liver steatosis as measured by transient elastography with controlled attenuation parameter in HIV-infected patients.

Objective: To assess the prevalence and factors associated with significant hepatic steatosis (SHS, steatosis involving ≥10% hepatocytes) in HIV-infected patients.

Design: A prospective, cross-sectional study.

Methods: Five hundred and five HIV-infected patients were included in this study.

Incidence of hepatocellular carcinoma in HIV-infected patients with cirrhosis: a prospective study.

: This study assesses the incidence of hepatocellular carcinoma (HCC) in a prospective cohort of HIV-infected patients, the majority receiving antiretroviral therapy, with liver cirrhosis from different etiologies, enrolled between 2004 and 2005 with median follow-up of 5 years. We followed 371 patients, 25.6% with decompensated cirrhosis at baseline.

Pulse wave velocity as index of arterial stiffness in HIV-infected patients compared with a healthy population.

Background: Chronic HIV infection leads to premature atherosclerosis. Arterial stiffness is considered a subclinical marker of cardiovascular disease.

Methods: Pulse wave velocity (PWV) was determined in 254 individuals (174 HIV-infected patients and 80 healthy controls, 2:1 matched by age and gender) to compare the prevalence of arterial stiffness and to identify associated factors.

Early but limited effects of raltegravir intensification on CD4 T cell reconstitution in HIV-infected patients with an immunodiscordant response to antiretroviral therapy.

Background: Immune hyperactivation in immunodiscordant patients can induce residual HIV replication and limit CD4 T cell recovery. We assessed the impact of raltegravir intensification on CD4 T cell recovery and viral persistence.

Methods: We performed a randomized, controlled, pilot trial.

Sustained virological response to interferon plus ribavirin reduces non-liver-related mortality in patients coinfected with HIV and Hepatitis C virus.

Background: Sustained virological response (SVR) after therapy with interferon plus ribavirin reduces liver-related complications and mortality in patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). We assessed the effect of SVR on HIV progression and mortality not related to liver disease.

Methods: An observational cohort study including consecutive HIV/HCV-coinfected patients treated with interferon plus ribavirin between 2000 and 2008 in 19 centers in Spain.

Effect of liver fibrosis on long-term mortality in HIV/hepatitis C virus-coinfected individuals who are evaluated to receive interferon therapies in the highly active antiretroviral therapy era.

The factors associated with overall mortality and liver decompensation in HIV and hepatitis C virus (HCV)-coinfected patients who are evaluated to receive HCV antiviral therapy with a known liver histological fibrosis stage were evaluated in a prospective cohort study. A total of 387 consecutive HIV/HCV-coinfected patients attending an outpatient clinical unit between January 1997 and December 2007 who fulfilled criteria to be treated with interferon and to whom liver biopsy was performed were included and followed every 6 months from time of liver biopsy to death or to December 2008. The follow-up period was 6.

Changes in T-cell subsets in HIV-HCV-coinfected patients during pegylated interferon-alpha2a plus ribavirin treatment.

Background: We evaluated the effect of different doses of pegylated interferon (PEG-IFN)-alpha2a/ribavirin (RBV) on several T-cell activation markers in HIV-HCV-coinfected patients and their relationship with changes in plasma HCV RNA.

Methods: Frozen peripheral blood mononuclear cells (PBMCs) from 22 patients receiving two different PEG-IFN-alpha2a schedules were analysed by six-colour flow cytometry. Cell-surface expression of CD38 was quantified.

Ability of treatment week 12 viral response to predict long-term outcome in genotype 1 hepatitis C virus/HIV coinfected patients.

Objective: Guidelines recommendation to extend treatment duration in genotype 1 hepatitis C virus (HCV)/HIV-coinfected patients who clear the virus later than treatment week 4 is not evidence-based. Our main objective was to study the ability of week 12 viral response [early virologic response (EVR)] to predict long-term outcome in patients treated for 48 weeks.

Design: Multicenter retrospective cohort analysis.

Virological, immunological, and clinical impact of switching from protease inhibitors to nevirapine or to efavirenz in patients with human immunodeficiency virus infection and long-lasting viral suppression.

Seventy-seven subjects infected with human immunodeficiency virus were randomized to switch from protease inhibitor (PI) therapy to nevirapine therapy (group A; n=26) or to efavirenz therapy (group B; n=25) or to continue PI therapy (group C; n=26). At month 12, viral suppression had been maintained in 96% of patients in group A, 92% of patients in group B, and 92% of patients in group C. A significant increase in the CD4(+) level was observed in all 3 groups.
