Brief Report: Coordinated Modulation of Circulating miR-21 in HIV, HIV-Associated Pulmonary Arterial Hypertension, and HIV/Hepatitis C Virus Coinfection.

ABSTRACT: Dysregulation of microRNA-21 (miR-21) is independently associated with HIV infection, pulmonary arterial hypertension (PAH), and hepatitis C virus (HCV) infection. To assess the expression of miR-21 in these overlapping comorbidities, we measured plasma miR-21 in HIV with and without PAH and then stratified by concomitant HCV infection. MiR-21 was increased in HIV and HIV-PAH versus uninfected subjects, but it did not differ between these groups. HIV/HCV coinfection correlated with even higher miR-21 levels within the HIV-infected population. These data reveal specific regulation of plasma miR-21 in HIV, HIV/HCV coinfection, and PAH and suggest that miR-21 may integrate complex disease-specific signaling in the setting of HIV infection.

Neurohormonal modulation in pulmonary arterial hypertension.

Project description:Pulmonary hypertension is a fatal condition of elevated pulmonary pressures, complicated by right heart failure. Pulmonary hypertension appears in various forms; one of those is pulmonary arterial hypertension (PAH) and is particularly characterised by progressive remodelling and obstruction of the smaller pulmonary vessels. Neurohormonal imbalance in PAH patients is associated with worse prognosis and survival. In this back-to-basics article on neurohormonal modulation in PAH, we provide an overview of the pharmacological and nonpharmacological strategies that have been tested pre-clinically and clinically. The benefit of neurohormonal modulation strategies in PAH patients has been limited by lack of insight into how the neurohormonal system is changed throughout the disease and difficulties in translation from animal models to human trials. We propose that longitudinal and individual assessments of neurohormonal status are required to improve the timing and specificity of neurohormonal modulation strategies. Ongoing developments in imaging techniques such as positron emission tomography may become helpful to determine neurohormonal status in PAH patients in different disease stages and optimise individual treatment responses.

Pseudohyponatremia in a patient with HIV and hepatitis C coinfection.

Project description:Pseudohyponatremia refers to low serum sodium in the presence of normal plasma tonicity. Whereas pseudohyponatremia secondary to hyperlipidemia is a commonly recognized occurrence, falsely low sodium levels secondary to elevated protein are less frequently observed. We present in this paper the case of a man coinfected with HIV and hepatitis C who had pseudohyponatremia from hypergammaglobulinemia. As hypergammaglobulinemia is a frequent occurrence in both HIV and HCV, we suggest that pseudohyponatremia is an important and likely underdiagnosed phenomenon in this patient population. Clinicians need to be aware of the electrolyte exclusion effect and become familiar with the techniques used by their local laboratory in the measurement of serum electrolytes. Pseudohyponatremia should also be included in the differential diagnosis of an elevated osmolal gap, as the falsely lowered sodium level will lead to a falsely low calculated serum osmolality.

HIV and Hepatitis B coinfection among perinatally HIV-infected Thai adolescents.

Project description:This study aimed to determine the prevalence of hepatitis B virus (HBV) coinfection and HBV seropositivity in perinatally HIV-infected adolescents. A secondary objective was to describe the clinical characteristics of adolescents with chronic HBV/HIV coinfection.Multicenter cross-sectional study of perinatally HIV-infected adolescents aged 12-25 years. HBV surface antigen, surface antibody (anti-HBs) and core antibody (anti-HBc) were measured. Coinfection was defined as having persistently positive HBV surface antigen. Seroprotective antibody from immunization was defined as having anti-HBs ?10 mIU/mL with negative anti-HBc. HBV DNA quantitation and rtM204V/I mutation analysis (lamivudine resistance-associated mutation) were performed in adolescents with chronic HBV infection.From November 2010 to March 2011, 521 patients were enrolled. Mean (SD) of CD4 lymphocyte count was 685 (324) cells/?L. The prevalence of HBV/HIV coinfection was 3.3% (95% confidence interval: 1.9-5.2%). Protective antibody against HBV was found in 18% of population, and this was significantly higher among adolescents who received than those who did not receive HBV revaccination after receiving antiretroviral therapy (93% versus 6%, P < 0.01). Among adolescents with chronic HBV infection, 88% have received lamivudine; however, 69% have HBV DNA >10 copies/mL and 75% had the rtM204V/I mutation.The prevalence of HBV coinfection in HIV-infected Thai adolescents was 3.3%. Most HIV-infected adolescents had no HBV protective antibody; therefore, revaccination with HBV vaccine is encouraged. The high prevalence of HBV-lamivudine resistance underscores the importance of HBV screening prior to antiretroviral therapy initiation to guide the selection of optimal regimen for coinfected children.

HIV-hepatitis B virus coinfection: epidemiology, pathogenesis, and treatment.

Project description:: HIV infection has a significant impact on the natural history of chronic hepatitis B virus (HBV) infection, with increased levels of HBV DNA, accelerated progression of liver disease and increased liver-associated mortality compared with HBV monoinfection. Widespread uptake and early initiation of HBV-active antiretroviral therapy has substantially improved the natural history of HIV-HBV coinfection but the prevalence of liver disease remains elevated in this population. In this paper, we review recent studies examining the natural history and pathogenesis of liver disease and seroconversion in HIV-HBV coinfection in the era of HBV-active antiretroviral therapy and the effects of HIV directly on liver disease. We also review novel therapeutics for the management of HBV with a particular emphasis on clinical strategies being developed for an HBV cure and an HIV cure and their impact on HIV-HBV coinfected individuals.

An Overview of Circulating Pulmonary Arterial Hypertension Biomarkers

Project description:Pulmonary arterial hypertension (PAH), also known as Group 1 Pulmonary Hypertension (PH), is a PH subset characterized by pulmonary vascular remodeling and pulmonary arterial obstruction. PAH has an estimated incidence of 15–50 people per million in the United States and Europe, and is associated with high mortality and morbidity, with patients' survival time after diagnosis being only 2.8 years. According to current guidelines, right heart catheterization is the gold standard for diagnostic and prognostic evaluation of PAH patients. However, this technique is highly invasive, so it is not used in routine clinical practice or patient follow-up. Thereby, it is essential to find new non-invasive strategies for evaluating disease progression. Biomarkers can be an effective solution for determining PAH patient prognosis and response to therapy, and aiding in diagnostic efforts, so long as their detection is non-invasive, easy, and objective. This review aims to clarify and describe some of the potential new candidates as circulating biomarkers of PAH.

Hepatitis C virus/HIV coinfection and responses to initial antiretroviral treatment.

Project description:To explore the relationship between hepatitis C virus (HCV)/HIV coinfection and responses to initial antiretroviral treatment (ART).Four AIDS Clinical Trials Group HIV treatment studies' data were combined to compare initial ART responses between HCV/HIV-coinfected and HIV-monoinfected patients as evaluated by virologic failure, CD4 cell measures, occurrence of AIDS/death and grade 3/4 safety events, using Kaplan-Meier estimates and proportional hazard, regression and mixed effects models, adjusting for baseline covariates.Of the 3041 included participants, 81% were men, 19% had prior history of AIDS, the median (25th, 75th percentile) baseline HIV RNA was 4.72 (4.38-5.18)?log10?copies/ml, and the median (25th, 75th percentile) baseline CD4 cell count was 216.0 (76.5-327.0)?cells/?l. The 279 HCV/HIV-coinfected individuals were older (44 vs. 37 years), more likely to be black non-Hispanic (47 vs. 36%), and previous/current intravenous drug user (52 vs. 5%) than the 2762 HIV-monoinfected patients (all P values <0.001). HCV/HIV coinfection was associated with earlier virologic failure, hazard ratio (95% confidence interval): 1.43 (1.07-1.91); smaller mean CD4 cell increase and CD4% increase [-33.8 (-52.2 to -15.4)?cells/?l and -1.16% (-1.43 to -0.89%), respectively] over a median of 132 weeks of follow-up; earlier occurrence of grade 3/4 safety event, hazard ratio 1.51 (1.26-1.81); and increased AIDS/mortality, hazard ratio 2.10 (1.31-3.37). Treatment effects comparing antiretroviral regimens were not significantly different by HCV/HIV coinfection status.HCV/HIV coinfection is associated with attenuated response to ART. Results support earlier initiation of HIV therapy and increased monitoring of those initiating ART with HCV/HIV coinfection.

Metabolic syndrome, neurohumoral modulation, and pulmonary arterial hypertension.

Project description:Pulmonary vascular disease, including pulmonary arterial hypertension (PAH), is increasingly recognized to be affected by systemic alterations including up-regulation of the renin-angiotensin-aldosterone system and perturbations to metabolic pathways, particularly glucose and fat metabolism. There is increasing preclinical and clinical data that each of these pathways can promote pulmonary vascular disease and right heart failure and are not simply disease markers. More recently, trials of therapeutics aimed at neurohormonal activation or metabolic dysfunction are beginning to shed light on how interventions in these pathways may affect patients with PAH. This review will focus on underlying mechanistic data that supports neurohormonal activation and metabolic dysfunction in the pathogenesis of PAH and right heart failure as well as discussing early translational data in patients with PAH.

Brief Report: Relationship Between ABCC4 SNPs and Hepatitis B Virus Suppression During Tenofovir-Containing Antiretroviral Therapy in Patients With HIV/HBV Coinfection.

Project description:BackgroundIncomplete hepatitis B virus (HBV) suppression during antiretroviral therapy (ART) in HIV and HBV coinfected patients is common, but underlying factors are not fully elucidated. We hypothesize that genetic factors that influence nucleoside analog pharmacokinetics will affect HBV treatment response.MethodsHIV/HBV coinfected patients on tenofovir disoproxil fumarate/lamivudine (TDF/3TC)-containing ART were enrolled. Selected ABCC4 single nucleotide polymorphisms (SNPs) with known effects on nucleoside pharmacokinetics were genotyped using TaqMan assays. Relationship between ABCC4 SNPs and unsuppressed HBV DNA (HBV DNA ?20 IU/mL) were examined.ResultsOf the 50 participants on TDF/3TC-containing ART for a median (range) of 1.5 (1-7.4) years, 20 (40%) had unsuppressed HBV DNA. Participants with unsuppressed compared with those with suppressed HBV DNA were more likely to have negative HBe antibody, lower body mass index, and lower CD4 count at enrollment. Carriers of ABCC4 rs11568695 (G3724A) variant allele were more likely than noncarriers to have unsuppressed HBV (61.1% vs. 29.0%, P = 0.038). Among 36 patients with suppressed HIV RNA (presumed good ART adherence), ABCC4 rs11568695 variant carriers were more likely than noncarriers to have unsuppressed HBV (58.8% vs. 20.0% P = 0.021). Logistic regression analysis that included genetic and nongenetic factors identified ABCC4 rs11568695 variant allele, body mass index, and male sex as predictors of unsuppressed HBV DNA.ConclusionsWe identified a novel association between ABCC4 rs11568695 SNP and poor HBV treatment response. If confirmed in further studies, ABCC4 genotyping could be used to identify individuals who may need intensified HBV therapy.

Compartmentalization of hepatitis C virus (HCV) during HCV/HIV coinfection.

Project description:Extrahepatic replication has important implications for the transmission and treatment of hepatitis C virus (HCV). We analyzed longitudinal HCV diversity in peripheral-blood mononuclear cells (PBMCs) and serum during HCV monoinfection and HCV/HIV coinfection to determine whether distinct amino acid signatures characterized HCV replicating within PBMCs. Analysis of E1-HVR1 sequences demonstrated higher serum genetic distances among HCV/human immunodeficiency virus (HIV)-coinfected persons. Moreover, consensus PBMC sequences were rarely identical to those in the corresponding serum, suggesting divergence in these 2 compartments. Three of 5 HCV/HIV-coinfected participants showed evidence of HCV compartmentalization in PBMCs. Additionally, signature sequence analysis identified PBMC-specific amino acids in all HCV/HIV-coinfected persons. To our knowledge, this is the first study to identify specific amino acids that may distinguish HCV variants replicating in PBMCs. It is provocative to speculate that extrahepatic HCV diversity may be an important determinant of treatment response and thus warrants additional study, particularly during HCV/HIV coinfection.

Pioglitazone for Hepatic Steatosis in HIV/Hepatitis C Virus Coinfection.

Project description:Chronic hepatitis C infection frequently coexists with human immunodeficiency virus (HIV) and together are associated with increased hepatic steatosis. Steatosis is a risk factor for progression of liver disease and may persist despite a sustained virologic response to hepatitis C treatment. Therefore, therapies to target hepatic steatosis are important for individuals with HIV and hepatitis C virus (HCV) coinfection. We completed a 48-week, randomized, double-blind, placebo-controlled trial of pioglitazone (45?mg/day) in 13 subjects with HIV/HCV coinfection. The primary outcome variable was hepatic fat content, measured by magnetic resonance spectroscopy (MRS) imaging. Individuals randomized to pioglitazone had a significant decrease in hepatic fat content measured by MRS from baseline (15.1?±?7.0%) to week 48 (7.6?±?3.9%), with a mean difference of -7.4% (p?=?0.02, n?=?5). There was no significant change in hepatic fat content with placebo. Glycemic control as measured by oral glucose challenge improved significantly with pioglitazone (p?=?0.047). Though not statistically significant, there were trends toward improved alanine aminotransferase (ALT) and histopathologic grade of steatosis in subjects who received pioglitazone. Pioglitazone was well tolerated and no one discontinued due to side effects. This study demonstrates that 48 weeks of pioglitazone therapy, and not placebo, results in significant reductions in hepatic fat content as measured by MRS in subjects with HIV and HCV coinfection and hepatic steatosis. This small study shows that pioglitazone helps ameliorate steatosis in the context of HIV/HCV coinfection.
