Abstract
BACKGROUND In TANGO, switching to dolutegravir/lamivudine was noninferior at 48 weeks to continuing 3-/4-drug tenofovir alafenamide-based regimens in virologically suppressed individuals with HIV-1. Antiretroviral agents have been associated with weight gain and metabolic complications. SETTING One hundred thirty-four centers; 10 countries. METHODS We assessed weight; fasting lipids, glucose, and insulin; and prevalence of insulin resistance and metabolic syndrome at baseline and week 48 in TANGO participant subgroups by boosting agent use in baseline regimens (boosted and unboosted). RESULTS In each treatment group, 74% of participants used boosted regimens at baseline. In boosted and unboosted subgroups, weight and fasting glucose changes at week 48 were small and similar between treatment groups. Overall and in the boosted subgroup, greater decreases from baseline were observed with dolutegravir/lamivudine in fasting total cholesterol (P < 0.001), low-density lipoprotein cholesterol (P < 0.001), triglycerides (P < 0.001), total cholesterol/high-density lipoprotein cholesterol ratio (overall, P = 0.017; boosted, P = 0.007), and insulin (boosted, P = 0.005). Prevalence of HOMA-IR ≥2 was significantly lower at week 48 with dolutegravir/lamivudine overall [adjusted odds ratio (aOR), 0.59; 95% confidence interval (CI), 0.40 to 0.87; P = 0.008] and in the boosted subgroup [aOR, 0.56; 95% CI, 0.36 to 0.88; P = 0.012] but not in the unboosted subgroup [aOR, 0.70; 95% CI, 0.31 to 1.58; P = 0.396]. Prevalence of metabolic syndrome at week 48 was low and consistent between treatment groups overall, with differences trending to favor dolutegravir/lamivudine in the unboosted subgroup [aOR, 0.41; 95% CI, 0.15 to 1.09; P = 0.075]. CONCLUSION Generally, switching from 3-/4-drug tenofovir alafenamide-based regimens to dolutegravir/lamivudine improved metabolic parameters, particularly when switching from boosted regimens. Because of smaller sample size in the unboosted subgroup, results warrant further investigation.

Abstract
Introduction: Efficient antiretroviral-treatment (ART) generally allows control of HIV infection. However, persons-living-with-HIV (PLWH), when aging, present a high prevalence of metabolic diseases. Area covered: Altered adiposity, dyslipidemias, insulin resistance, diabetes, and their consequences are prevalent in PLWH and could be partly related to ART. Expert opinion: At first, personal and lifestyle factors are involved in the onset of these complications. The persistence of HIV in tissue reservoirs could synergize with some ART and enhance metabolic disorders. Altered fat repartition, diagnosed as lipodystrophy, has been related to first-generation nucleoside-reverse-transcriptase-inhibitors (NRTIs) (stavudine zidovudine) and some protease inhibitors (PIs). Recently, use of some integrase-inhibitors (INSTI) resulted in weight/fat gain, which represents a worrisome unresolved situation. Lipid parameters were affected by some first-generation NRTIs, non-NRTIs (efavirenz) but also PIs boosted by ritonavir, with increased total and LDL-cholesterol and triglycerides. Insulin resistance is common associated with abdominal obesity. Diabetes incidence, high with first-generation-ART (zidovudine, stavudine, didanosine, indinavir) has declined with contemporary ART close to that of the general population. Metabolic syndrome, a dysmetabolic situation with central obesity and insulin resistance, and liver steatosis are common in PLWH and could indirectly result from ART-associated fat gain and insulin resistance. All these dysmetabolic situations increase the atherogenic cardiovascular risk.

Abstract
OBJECTIVES In the general population, metabolic health often declines as BMI increases. However, some obese individuals maintain metabolic health. HIV and antiretroviral therapy have been associated with metabolic disturbances. We hypothesized that HIV-infected (HIV) men on suppressive antiretroviral therapy experience less metabolic health than HIV-uninfected (HIV) men across all BMI categories. DESIGN/METHODS In a cross-sectional analysis of 1018 HIV and 1092 HIV men enrolled in the multicenter AIDS cohort study, Poisson regression with robust variance determined associations between HIV serostatus and metabolic health prevalence (defined as meeting ≤2 of 5 National Cholesterol Education Program Adult Treatment Panel III metabolic syndrome criteria), adjusting for age, race, BMI category, smoking, and hepatitis C virus infection status. RESULTS HIV men were younger (54 vs. 59 years) and had lower median BMI (25 vs. 27 kg/m). Nonobese HIV men had lower metabolic health prevalence than HIV men (BMI ≤25 kg/m: 80 vs. 94%, P < 0.001; BMI 25-29 kg/m: 64 vs. 71%, P = 0.05), but metabolic health prevalence among obese men did not differ by HIV serostatus (BMI 30-34 kg/m: 35 vs. 39%, P = 0.48; BMI ≥35 kg/m: 27 vs. 25%, P = 0.79). In the adjusted model, nonobese HIV men were less likely to demonstrate metabolic health than nonobese HIV men. Among HIV men, per year darunavir, zidovudine, and stavudine use were associated with lower metabolic health likelihood. CONCLUSION Metabolically healthy obesity prevalence does not differ by HIV serostatus. However, among nonobese men, HIV infection is associated with lower metabolic health prevalence, with associations between lack of metabolic health and darunavir and thymidine analog nucleoside reverse transcriptase inhibitor exposure observed.

Abstract
OBJECTIVE The aim of this study was to estimate the long-term metabolic effects of initiating a lopinavir/ritonavir (LPV/r)-based regimen as a first-line therapy for HIV-infected children less than 3 years of age in resource-limited settings. DESIGN A prospective cohort study after conclusion of the P1060 randomized clinical trials (ClinicalTrials.gov Identifier: NCT00307151), with an overall follow-up of 7 years. METHODS Longitudinal total cholesterol and triglyceride measures were compared between 222 and 227 children randomized to initiate LPV/r and nevirapine (NVP)-based regimens, respectively. Adipokines (adiponectin and leptin) and biomarkers of inflammation [C-reactive protein and interleukin (IL)-6], microbial translocation (lipopolysaccharide) and immune activation (sCD14), measured in 117 participants at a median of 45 weeks of follow-up, were also compared by a randomized arm. RESULTS Mean total cholesterol and the percentage of participants with borderline or high total cholesterol was higher in the LPV/r arm from years 3 to 7 of follow-up than in the NVP arm (adjusted relative differences ranging from 10.9 to 23.4 mg/dl and adjusted relative risks ranging from a 60% increased risk to a more than four-fold increased risk for cholesterol ≥170 mg/dl at 7 years of follow-up). Initiation of a LPV/r-based regimen was not associated with high triglycerides over follow-up or large differences in markers of metabolic syndrome, inflammation, microbial translocation or immune activation. CONCLUSION Given the virologic superiority of LPV/r-based regimens in young children and open questions regarding the roll-out of dolutegravir in resource-limited settings, children are currently being maintained on LPV/r-based regimens. Our results suggest continual assessment of total cholesterol among young children initiating a LPV/r-based regimen to monitor cardiometabolic health.

Abstract
OBJECTIVE Few studies have investigated irisin and FGF21 to elucidate the role of these hormones to regulate 'beiging' in HIV-infected patients. DESIGN Fifty HIV-infected subjects with the metabolic syndrome were previously recruited and randomized to receive lifestyle modification (LSM) and/or metformin over 12 months. In the current study, we assessed FGF21 and irisin at baseline and after intervention. In addition, we assessed circulating FGF21 and irisin in relationship to brown adipose tissue (BAT) gene expression in dorsocervical subcutaneous fat biopsies from 13 HIV-infected subjects. RESULTS At baseline, prior to intervention, HIV-infected subjects demonstrated increased log FGF21 (2·13 ± 0·06 vs 1·98 ± 0·05 pg/ml, P = 0·05) and log irisin (0·33 ± 0·02 vs 0·17 ± 0·04 μg/ml, P = 0·003) compared with healthy controls well matched based on waist circumference. After 12 months, HIV-infected subjects randomized to LSM demonstrated a relative reduction in FGF21 compared with those not randomized to LSM (-10 [-35,22] vs 40 [0,94] %change, P = 0·01). Changes in FGF21 were inversely associated with improved parameters of energy homoeostasis, including increased REE (ρ = -0·34, P = 0·046) and max VO2 (ρ = -0·38, P = 0·02), and reduced RQ (ρ = 0·40, P = 0·02) among all HIV-infected subjects. Increased UCP-1 (r = 0·75, P = 0·003), DIO2 (r = 0·58, P = 0·04) and CideA (r = 0·73, P = 0·01) gene expression in dorsocervical fat was significantly associated with FGF21 in HIV-infected subjects. CONCLUSION HIV-infected subjects with metabolic complications demonstrate increases in FGF21 in relationship to BAT gene expression. Relative reductions in FGF21 in those receiving long-term LSM relate to overall improvements in energy expenditure parameters. In contrast, irisin levels are elevated in HIV-infected subjects, but are not influenced by LSM nor associated with BAT gene expression.

Abstract
INTRODUCTION Lipodystrophy is a term used to describe a metabolic complication of fat loss, fat gain, or a combination of fat loss and gain, which is associated with some antiretroviral (ARV) therapies given to HIV-infected individuals. There is limited research on lipodystrophy in low- and middle-income countries, despite accounting for more than 95% of the burden of HIV/AIDS. The objective of this review was to evaluate the prevalence, pathogenesis and prognosis of HIV-related lipoatrophy, lipohypertrophy and mixed syndrome, to inform clinical management in resource-limited settings. METHODS We conducted a structured literature search using MEDLINE electronic databases. Relevant MeSH terms were used to identify published human studies on HIV and lipoatrophy, lipohypertrophy, or mixed syndrome in low-, low-middle- and upper-middle-income countries through 31 March 2014. The search resulted in 5296 articles; after 1599 studies were excluded (958 reviews, 641 non-human), 3697 studies were extracted for further review. After excluding studies conducted in high-income settings (n=2808), and studies that did not meet inclusion criteria (n = 799), 90 studies were included in this review. RESULTS AND DISCUSSION Of the 90 studies included in this review, only six were from low-income countries and eight were from lower middle-income economies. These studies focused on lipodystrophy prevalence, risk factors and side effects of antiretroviral therapy (ART). In most studies, lipodystrophy developed after the first six months of therapy, particularly with the use of stavudine. Lipodystrophy is associated with increased risk of cardiometabolic complications. This is disconcerting and anticipated to increase, given the rapid scale-up of ART worldwide, the increasing number and lifespan of HIV-infected patients on long-term therapy, and the emergence of obesity and non-communicable diseases in settings with extensive HIV burden. CONCLUSIONS Lipodystrophy is common in resource-limited settings, and has considerable implications for risk of metabolic diseases, quality of life and adherence. Comprehensive evidence-based interventions are urgently needed to reduce the burden of HIV and lipodystrophy, and inform clinical management in resource-limited settings.

Abstract
OBJECTIVE This consensus document is an update of metabolic disorders and cardiovascular risk (CVR) guidelines for HIV-infected patients. METHODS This document has been approved by an expert panel of GEAM, SPNS and GESIDA after reviewing the results of efficacy and safety of clinical trials, cohort and pharmacokinetic studies published in biomedical journals (PubMed and Embase) or presented in medical scientific meetings. Recommendation strength and the evidence in which they are supported are based on the GRADE system. RESULTS A healthy lifestyle is recommended, no smoking and at least 30min of aerobic exercise daily. In diabetic patients the same treatment as non-HIV infected patients is recommended. HIV patients with dyslipidemia should be considered as high CVR, thus its therapeutic objective is an LDL less than 100mg/dL. The antihypertensive of ACE inhibitors and ARAII families are better tolerated and have a lower risk of interactions. In HIV-patients with diabetes or metabolic syndrome and elevated transaminases with no defined etiology, the recommended is to rule out a hepatic steatosis Recommendations for action in hormone alterations are also updated. CONCLUSIONS These new guidelines update previous recommendations regarding all those metabolic disorders involved in CVR. Hormone changes and their management and the impact of metabolic disorders on the liver are also included.

Abstract
BACKGROUND Cardiovascular diseases (CVD) and metabolic alterations are among the majors public health concern that have been reported in people living with HIV infections. Factors contributing to cardio metabolic syndrome in HIV include body fat distribution, dyslipidemia, insulin resistance, cardiovascular dysfunction and inflammation. The aim of the study was to determine the effect of Spirulina platensis (Cyanobacteriaceae) supplementation versus local diet on lipid profile in HIV-infected antiretroviral-naive patients. METHODS A prospective single-blind, randomized, multicentre study was conducted from February 2010 to December 2012. A total of 320 HIV antiretroviral-naïve patients were screened and 169 were recruited in this study. Patients were randomized and received either Spirulina supplementation combined with local diet (n=82) or local diet only (n=87). Age, weight, body mass index (BMI), lipid profile, CD4 count, and local food intake variables were assessed on three separate occasions (three, six and twelve months). RESULTS An average age of the patients was 35.6±9 years. The majority of participants were female 67.1%. Regarding the lipid profile, there is a significant increase in HDL-cholesterol and a significant decrease in total cholesterol, LDL-cholesterol and triglycerides in the group of patients who consumed Spirulina platensis. A change in the atherogenic index defined by the ratio CT/HDL-C substitutable by LDL-C/HDL-C and the TC/HDL decreased significantly from 10.83 at baseline to 2.22 after 12 months (p=0.21 and p<0.0001) in the patients taking Spirulina. CONCLUSIONS Nutritional supplementation with Spirulina combined with a quantitative and qualitative balanced diet for at least six months can retard an exposition to lipid abnormalities in HIV-infected antiretroviral-naive patients. Further studies are recommended on a large group of people not infected with HIV and exposed to cardiovascular risk factors.

Abstract
OBJECTIVE Metabolic abnormalities including diabetes, dyslipidemia, hypertension, and abdominal obesity occur commonly in HIV patients, are associated with increased coronary artery calcification (CAC), and contribute to increased cardiovascular disease (CVD) in this population. We hypothesized that lifestyle modification (LSM) and metformin would improve CVD indices in HIV patients with metabolic syndrome. DESIGN A randomized, placebo-controlled trial to investigate LSM and metformin, alone and in combination, over 1 year, among 50 HIV-infected patients with metabolic syndrome. METHODS We assessed CAC, cardiovascular and metabolic indices. RESULTS Among the participants, duration of HIV-infection was 14 ± 1 year and duration of antiretroviral therapy was 6 ± 1 year. Metformin-treated patients demonstrated significantly less progression of CAC (-1 ± 2 vs. 33 ± 17, P = 0.004, metformin vs. placebo), whereas the effect of LSM on CAC progression was not significant (8 ± 6 vs. 21 ± 14, P = 0.82, LSM vs. no-LSM). Metformin had a significantly greater effect on CAC than LSM (P = 0.01). Metformin-treated patients also demonstrated less progression in calcified plaque volume (-0.4 ± 1.9 vs. 27.6 ± 13.8 μl, P = 0.008) and improved homeostatic model of assessment-insulin resistance (HOMA-IR) (P = 0.05) compared with placebo. Participants randomized to LSM vs. no-LSM showed significant improvement in HDL (P = 0.03), high-sensitivity C-reactive protein (hsCRP) (P = 0.05), and cardiorespiratory fitness. Changes in CAC among the four groups--no-LSM-placebo (43 ± 30); LSM-placebo (19 ± 7); no-LSM-metformin (1 ± 1) and LSM-metformin (-4 ± 6)--were different (P = 0.03 for ANOVA and linear trend across groups), and the majority of this effect was mediated by metformin. Results are mean ± SEM. CONCLUSION Metformin prevents plaque progression in HIV-infected patients with the metabolic syndrome.

Abstract
BACKGROUND Elevated serum triglyceride and low HDL-cholesterol concentrations have been reported in persons with HIV. OBJECTIVE The effect of a dietary intervention plus n-3 (omega-3) fatty acid supplementation on serum triglycerides and markers of insulin sensitivity was investigated. DESIGN Fifty-four persons with HIV and elevated serum triglycerides (>150 mg/dL) and/or abnormal Quantitative Insulin Sensitivity Check Index values (<0.35 but >0.30) were recruited for a dietary intervention in which total fat, type of fat, fiber, and glycemic load were controlled along with supplementation with n-3 fatty acids to achieve an intake of 6 g/d. The subjects were randomly assigned to an intervention or control group, and serum lipids, markers of insulin sensitivity, and serum phospholipid fatty acids were measured in both groups at baseline, 3 wk, and 13 wk. RESULTS Triglycerides in the intervention group decreased from a median of 180 mg/dL (interquartile range: 141, 396) to 114 mg/dL (interquartile range: 84, 169) from baseline to 3 wk, whereas they remained stable in the control group (P = 0.003). Serum phospholipid fatty acids indicated a decrease in de novo lipogenesis and a decrease in arachidonic acid (% nmol; P CONCLUSIONS Diet and n-3 fatty acid supplementation dramatically reduced serum triglycerides, decreased arachidonic acid in the phospholipids fraction, and appeared to decrease the de novo lipogenesis associated with the metabolic syndrome in the intervention group.
