Abstract
Background and aims Osteoprotegerin (OPG) is a tumor necrosis factor receptor superfamily member which increases in chronic inflammation and is associated with altered bone turnover and cardiovascular complications. In this study, we investigated whether OPG increases during acute inflammatory states induced by infections in children and correlated its levels with other biomarkers. Materials and methods This is a prospective study that included 59 patients with documented bacterial infections, 20 with viral infections and 20 healthy controls. OPG, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cells (WBC) were measured. Results OPG serum levels were significantly increased during inflammation induced by a bacterial infection, compared to viral infection and controls (4.17 pmol/l (2.40-12.12) vs 3.2 (1.66-5.33) and 3 pmol/l (2.13-4.76), respectively, p < 0.001). In addition, OPG correlated well with CRP (rho = 0.428, p = 0.0011), ESR (rho = 0.3, p = 0.026), and WBC (rho = 0.266, p = 0.05) only in the group with bacterial infection. The sensitivity of CRP in detecting a bacterial infection was superior to OPG (67.3% vs 38.3%). Conclusion This study provides proof of concept that OPG increases differentially in bacterial infections, although with a lower sensitivity than CRP. Further studies are needed to define the role of OPG during the inflammatory states of infection in pediatric infections.

FGF21 and its Relationship with Inflammatory and Metabolic Parameters in HIV Patients after Antiretroviral Treatment. Curr HIV Res 2020; 18:308-314. [PMID: 32684151 DOI: 10.2174/1570162x18666200719235625] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 06/19/2020] [Accepted: 07/30/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Fibroblast Growth Factor 21 (FGF21) serum levels are associated with insulin resistance and metabolic syndrome in HIV patients. OBJECTIVE To quantify FGF21 levels in HIV patients using antiretroviral therapy (ART) and to analyze a possible association between serum FGF21 levels and lipid profile, levels of proinflammatory cytokines, and atherogenic risk factors. MATERIALS AND METHODS Twenty patients with HIV infection, who received ART in a scheme consisting of Tenofovir/Emtricitabine+Lopinavir/Ritonavir, were enrolled in this study. The serum levels of FGF21, inflammatory parameters (IL-6 and IL-1β), glucose, cholesterol, triglycerides, and insulin were determined at baseline and after 36 weeks of treatment. The homeostatic model assessment for insulin resistance (HOMA-IR) and the atherogenic risk factor were also calculated. RESULTS After 36 weeks, serum FGF21 levels decreased significantly (p=0.011), whereas IL-6 levels (r=0.821, p=0.0001) and the CD4+ T cell count (r=0.446, p=0.048), showed a positive correlation with the decrease in FGF21 levels. There was an increase in total cholesterol (r=-0.483, p=0.031), LDL (r=-0.496, p=0.026), VLDL (r=-0.320, p=0.045), and the atherogenic index factor (r=-0.539, p=0.014), these values showed a negative correlation with FGF21 levels. CONCLUSION The decrease of serum FGF21 levels due to ART is associated with the alteration in lipid profile and an increased risk for cardiovascular diseases. These variations are predictors of inflammatory status in HIV patients using antiretroviral therapy.

Abstract
BACKGROUND The contributions of the receptor activator of nuclear factor kappa-B ligand (RANKL)/osteoprotegerin (OPG) axis to cardiovascular and bone disease in treated HIV-1 infection are not well defined. SETTING Prospective, observational, longitudinal study. METHODS In a subset analysis of a prospective randomized clinical trial, 234 HIV-1-infected antiretroviral therapy-naive participants received tenofovir-emtricitabine plus either atazanavir/ritonavir, darunavir/ritonavir, or raltegravir and achieved plasma HIV-1 RNA <50 copies per milliliter by week 24 and thereafter. Associations between plasma RANKL, OPG, or RANKL/OPG ratio levels with total, hip, and spine bone mineral density (BMD) loss or progression of carotid artery intima-media thickness were assessed longitudinally over 96 weeks. RESULTS Over 96 weeks, all treatment groups had similar and sustained declines in plasma RANKL, increases in plasma OPG, and subsequently, decreases in the RANKL/OPG ratio. There were no associations between plasma RANKL or RANKL/OPG ratio levels with total, hip, and spine BMD loss or progression of carotid artery intima-media thickness; however, plasma OPG in successfully treated HIV-infected patients (week 48 and 96) was associated with spine BMD loss. CONCLUSIONS In virologically suppressed HIV-infected patients, the evolution of bone disease could be linked to plasma OPG levels; however, the role of plasma levels of RANKL and RANKL/OPG ratio in the prediction of morbidity in treated HIV-1 infection may be limited.

Abstract
Background Non-invasive methods for assessing liver fibrosis are increasingly used as an alternative to liver biopsy. Recently, a score-based biochemical blood test (Coopscore©) was developed in a cohort of patients chronically infected with hepatitis C virus, showing higher diagnostic performances than Fibrometer®, Fibrotest®, Hepascore® and Fibroscan™. Here, we assess its performance in patients co-infected with the human immunodeficiency virus and hepatitis B virus. Methods Ninety-seven human immunodeficiency virus/hepatitis B virus co-infected patients with liver biopsies were included from a previously described cohort. Histological fibrosis staging using METAVIR criteria was used as the reference. Coopscore©, Fibrotest®, Fibrometer®, Hepascore® and Zeng score were computed and compared with the Coopscore© using the Obuchowski index and area under the receiving operator characteristic curves. Results The distribution of liver fibrosis levels was as follows: F0-F1 ( n = 42), F2 ( n = 25), F3 ( n = 15) and F4 ( n = 15). The Obuchowski index was higher for Coopscore© (0.774) than Fibrometer® (0.668), Hepascore® (0.690) and Zeng scores (0.704) ( P < 0.05), reflecting a better ability to discriminate between fibrosis stages. Similarly, when predicting significant fibrosis (≥F2), the AUROC was significantly greater for the Coopscore© (0.836) than the Hepascore® (0.727) and Zeng scores (0.746), but not for the Fibrotest® (0.778, P = 0.14) or Fibrometer® (0.790, P = 0.19). The Coopscore© did not show a higher capacity than other scores to predict advanced fibrosis (≥F3) or cirrhosis (F4). Conclusions This study supports the diagnostic value of the Coospcore© in fibrosis staging among human immunodeficiency virus/hepatitis B virus co-infected patients, especially to predict significant fibrosis.

Abstract
OBJECTIVES The aim of the study was to determine the effect of alendronate (ALN) on inflammatory markers and osteoprotegerin (OPG)/receptor activator of nuclear factor-kappaB ligand (RANKL), and to explore the associations of baseline systemic inflammation and vitamin D status on the bone mineral density (BMD) response to ALN. METHODS Eighty-two HIV-positive patients with lumbar spine T-score ≤ -1.5 were randomized to ALN 70 mg weekly or placebo for 48 weeks; all received calcium carbonate 500 mg/vitamin D3 200 IU twice daily. Serum C-telopeptide (CTx) and BMD were assessed at baseline and week 48. Stored plasma samples in 70 subjects were assayed for levels of 25-hydroxyvitamin D (25(OH)D), OPG, RANKL, interleukin (IL)-6 and soluble receptors for tumour necrosis factor (TNF)-α 1 and 2 (sTNFR 1 and 2). RESULTS ALN increased BMD more than placebo at both the lumbar spine (difference ALN - placebo 2.64%; P = 0.011) and the total hip (difference 2.27%; P = 0.016). No within- or between-arm differences in OPG, RANKL or inflammatory markers were observed over 48 weeks. High baseline CTx and sTNFR2 were associated with a more robust BMD response to ALN over 48 weeks at the lumbar spine [difference 5.66%; 95% confidence interval (CI) 3.50, 7.82; P < 0.0001] and total hip (difference 4.99%; 95% CI 2.40, 7.57; P = 0.0002), respectively. Baseline 25(OH)D < 32 ng/mL was associated with larger increases in total hip BMD over 48 weeks, independent of ALN treatment (P = 0.014). CONCLUSIONS Among HIV-positive patients, higher baseline bone resorption and TNF-α activity were associated with an increased BMD response to ALN. The greater BMD response in those with lower vitamin D reinforces the importance of vitamin D supplementation with bisphosphonate treatment.

Abstract
CONTEXT Abnormalities in the osteoprotegerin (OPG)/receptor activator of nuclear factor-κB ligand (RANKL) axis have been observed in HIV-infected persons and have been implicated in cardiovascular disease (CVD) pathogenesis in the general population. OBJECTIVE To determine associations of serum OPG and RANKL concentrations with HIV infection and subclinical atherosclerosis. DESIGN Cross-sectional study nested within the Multicenter AIDS Cohort Study. SETTING Four US academic medical centers. PARTICIPANTS There were 578 HIV-infected and 344 HIV-uninfected men. MAIN OUTCOME MEASURES Coronary artery calcium (CAC) was measured by noncontrast cardiac computed tomography, and coronary stenosis and plaque characteristics (composition, presence, and extent) were measured by coronary computed tomography angiography. All statistical models were adjusted for traditional CVD risk factors. RESULTS OPG concentrations were higher, and RANKL concentrations were lower among HIV-infected men compared with HIV-uninfected men (P < 0.0001 each). Among HIV-infected men, higher OPG concentrations were associated with the presence of CAC, mixed plaque, and coronary stenosis >50%, but not with plaque extent. In contrast, among HIV-uninfected men, higher OPG concentrations were associated with the extent of both CAC and calcified plaque, but not with their presence. RANKL concentrations were not associated with plaque presence or the extent among HIV-infected men, but among HIV-uninfected men, lower RANKL concentrations were associated with greater extent of CAC and total plaque. CONCLUSIONS OPG and RANKL are dysregulated in HIV-infected men, and their relationship to the presence and extent of subclinical atherosclerosis varies by HIV status. The role of these biomarkers in CVD pathogenesis and risk prediction may be different in HIV-infected men.

Abstract
Background In the past years many inflammatory markers have been studied in association with clinically manifest cardiovascular disease (CVD) and carotid intima-media thickness (CIMT) in HIV-infected patients, to obtain insights in the increased cardiovascular risk observed in HIV infection. This systematic review provides an oversight of the current knowledge. Methods A search was performed in PubMed, Embase and Cochrane in July 2014, identifying all articles from 1996 onwards addressing the relation between inflammatory markers and CVD or CIMT in HIV-positive adults. Two authors, using predefined criteria, independently conducted the selection of articles, critical appraisal and extraction of the data. Analysis was focused on the immune markers that were most frequently assessed. The review protocol was registered in the PROSPERO database at 11 July 2014 (registration number CRD42014010516). This review was performed according to the PRISMA guideline. Findings Forty articles were selected; eight addressing cardiovascular disease (CVD) and thirty-two addressing CIMT. C-reactive protein (CRP), interleukin-6 (IL-6) and d-dimer were assessed most frequently in relation to the occurrence of CVD; in four out of eight studies. All three markers were positively related to CVD in three out of four studies. Studies addressing CIMT were too heterogeneous with respect to patient populations, inflammatory markers, CIMT measurement protocols and statistical methods to allow for a formal meta-analysis to obtain summary statistics. CRP, IL-6 and soluble vascular cell adhesion molecule (sVCAM-1) were the most studied markers in relation to CIMT. None of the inflammatory markers showed an association with CIMT. Interpretation This review showed a relation between some inflammatory markers and CVD, however, no consistent relation is observed for CIMT. Statistical approaches that yields effect estimates and standardized CIMT protocols should be chosen. Further research should focus on prospective studies and a selected set of inflammatory markers.

Abstract
BACKGROUND HIV-infected persons are at increased cardiovascular disease (CVD) risk, but traditional CVD therapies are understudied in this population. Telmisartan is an angiotensin receptor blocker (ARB) and peroxisome proliferator-activated receptor-gamma (PPAR-gamma) agonist that improves endothelial function and cardiovascular mortality in HIV-uninfected populations. We assessed the effects of telmisartan on endothelial function in older HIV-infected persons at risk for CVD in a small pilot study. METHODS HIV-infected individuals≥50 years old on suppressive antiretroviral therapy (ART) with ≥1 traditional CVD risk factor received open-label telmisartan 80 mg daily for 6 weeks. Brachial artery flow-mediated dilation (FMD) measured endothelial function. The primary endpoint was 6-week change in maximum relative FMD. RESULTS Seventeen participants enrolled; 16 completed all evaluations (88% men, 65% non-White, median age 60 years, CD4+T lymphocyte count 625 cells/mm3). Antiretroviral therapy included 71% protease inhibitor (PI), 29% non-nucleoside reverse transcriptase inhibitor (NNRTI), 29% integrase inhibitor, 65% tenofovir, and 29% abacavir. Cardiovascular disease risk factor prevalence included 76% hyperlipidemia, 65% hypertension, 18% smoking, and 12% diabetes mellitus. After 6 weeks, statistically significant blood pressure changes were observed (systolic-16.0 mmHg, diastolic-6.0 mmHg) without significant changes in FMD. In subset analyses, FMD increased more among abacavir-treated, PI-treated, and non-smoking participants. CONCLUSIONS No significant FMD changes were observed after 6 weeks of telmisartan therapy; however, abacavir- and PI-treated participants and non-smokers showed greater FMD increases. Additional studies are needed to explore the effects of telmisartan on endothelial function among HIV-infected individuals with traditional CVD and/or ART-specific risk factors.

Abstract
Patients with HIV‑1 infection often develop multiple complications and comorbidities, including osteoporosis and atherosclerosis. The receptor activator of nuclear factor kappa-B/receptor activator of nuclear factor kappa-B ligand/osteoprotegerin axis has been identified as a possible common link between osteoporosis and vascular diseases. Since the discovery of this axis, much has been learned about its role in controlling skeletal biology and less about its role in the context of vascular biology. However, the exact role of the receptor activator of nuclear factor kappa-B ligand/osteoprotegerin axis in HIV infection is not completely understood. In this review we examine the mechanisms by which inflammation and immune dysregulation in HIV‑1 infection may impact bone turnover and atherogenesis through perturbations in the receptor activator of nuclear factor kappa-B/receptor activator of nuclear factor kappa-B ligand/osteoprotegerin axis.
