Abstract
Hypertriglyceridemia is common in antiretroviral therapy-treated patients and Omega 3 fatty acids are being used as a intervention in reducing serum triglycerides (TG) in these patients. The objective of this study is to evaluate the effectiveness of the use of Omega 3 in the treatment of hypertriglyceridemia in HIV/AIDS patients on antiretroviral therapy. This study is a systematic review with meta-analysis of randomized clinical trials. Electronic databases - PubMed, Cochrane and Lilacs were researched. Fifty one articles were encountered. Nine were added to the meta-analysis. The reduction of triglycerides level was -77.55 mg (IC of -121.85 to -33.25) in Omega 3 groups. The analysis considering trials with more than 1000 mg of EPA/DHA included seven studies and the heterogeneity dropped to 0%.The reduction of combined averages was -101.56mg (IC of -145.76 to -57.37). The analysis considering trials with patients that had more than 200 mg/dL of initial triglycerides included also seven trials and the heterogeneity dropped to 0%. The reduction of combined averages was -114.15 mg (IC of -162.34 to -65.97). EPA/DHA supplementation reduces serum triglycerides levels in patients with HIV/AIDS-associated hypertriglyceridemia in stable use of antiretroviral therapy.

Abstract
The introduction of potent combination antiretroviral therapy (cART) has had a remarkable impact on the natural history of HIV infection, leading to a dramatic decline in the mortality rate and a considerable increase in the life expectancy of HIV-positive people. However, cART use is frequently associated with several metabolic complications, mostly represented by lipid metabolism alterations, which are reported very frequently among persons treated with antiretroviral agents. In particular, hyperlipidaemia occurs in up to 70%-80% of HIV-positive subjects receiving cART and is mainly associated with specific antiretroviral drugs belonging to three classes of antiretroviral agents: NRTIs, NNRTIs and PIs. The potential long-term consequences of cART-associated dyslipidaemia are not completely understood, but an increased risk of premature coronary heart disease has been reported in HIV-infected patients on cART, so prompt correction of lipid metabolism abnormalities is mandatory in this population. Dietary changes, regular aerobic exercise and switching to a different antiretroviral regimen associated with a more favourable metabolic profile are the first steps in clinical management, but lipid-lowering therapy with fibrates or statins is often required. In this case, the choice of hypolipidaemic drugs should take into account the potential pharmacokinetic interactions with many antiretroviral agents.

Abstract
OBJECTIVE To examine the effect of the alcoholic extract of lotus leaves (AELL) on antiretroviral treatment-induced dyslipidaemia in a rat model. METHODS Lotus leaves were extracted by 95% ethanol. Seventy male Sprague-Dawley rats were given lopinavir/ritonavir for six weeks. At week 0 and 6, sera were collected for measurement of total cholesterol (TC) and triglyceride (TG). Rats meeting the criteria for dyslipidaemia were assigned to four groups and received once daily for another four weeks lopinavir/ritonavir (group A), lopinavir/ritonavir plus 0.52 g/kg AELL (group B), lopinavir/ritonavir plus 0.26 g/kg AELL (group C), or lopinavir/ritonavir plus 0.13 g/kg AELL (group D), respectively. At weeks 8 and 10, blood samples were collected again for measurement of TC or TG. RESULTS Both TC and TG increased over time in group A during the observation period (weeks 6 to 10), however, TC and TG decreased in group B, and TG declined in group C. Neither TC nor TG could be reduced to a level near baseline. CONCLUSION Alcoholic extract of lotus leaves may have the potential to treat dyslipidaemia related to highly active antiretroviral therapy, but may not be potent enough to reduce TC or TG concentrations to goal levels when used alone.

Abstract
OBJECTIVE The goal of this study was to compare the effectiveness of fish oil, fenofibrate, gemfibrozil, and atorvastatin on reducing triglyceride (TG) levels among a large cohort of HIV-infected patients in clinical care. DESIGN Retrospective observational cohort study. METHODS The primary endpoint was absolute change in TG levels measured using the last TG value pretreatment and the first TG value posttreatment. A pre-post quasi-experimental design was used to estimate the change in TG because of initiating fish oil. Linear regression models examined the comparative effectiveness of treatment with fish oil versus gemfibrozil, fenofibrate, or atorvastatin for TG reduction. Models were adjusted for baseline differences in age, sex, race, CD4⁺ cell count, diabetes, body mass index, protease inhibitor use, and time between TG measures. RESULTS A total of 493 patients (mean age, 46 years; 95% male) were included (46 patients receiving gemfibrozil; 80, fenofibrate; 291, atorvastatin; and 76, fish oil) with a mean baseline TG of 347 mg/dL. New use of fish oil decreased TG [ΔTG, -45 mg/dL; 95% confidence interval (CI): -80 to -11] in the pre-post study. Compared with fish oil (reference), fibrates were more effective (ΔTG, -66; 95% CI: -120 to -12) in reducing TG levels, whereas atorvastatin was not (ΔTG, -39; 95% CI: -86 to 9). CONCLUSIONS In HIV-infected patients in routine clinical care, fish oil is less effective than fibrates (but not atorvastatin) at lowering TG values. Fish oil may still represent an attractive alternative for patients with moderately elevated TGs, particularly among patients who may not want or tolerate fibrates.

Abstract
HIV-associated lipodystrophy syndrome (HALS), comprising metabolic and morphological alterations, is a known side effect of highly active antiretroviral therapy (HAART). Evidence for the role of nutrition in the management of the systemic parameters of HALS is currently limited. In the present paper we review the current knowledge base surrounding HALS, focusing particularly on the role of nutrition in mitigating the systemic parameters of the syndrome. Reported prevalence of HALS was found to vary from 9 to 83 % due to lack of a standardised definition, as well as variations in assessment methods and in the study population used. HALS is associated with both morphological (lipoatrophy, lipohypertrophy) and metabolic (dyslipidaemia, glucose intolerance, diabetes, hypertension, endothelial dysfunction and atherosclerosis) alterations, which may occur singly or in combination, and are associated with an increased risk of CVD. HAART-induced adipocyte inflammation, oxidative stress and macrophage infiltration, as well as altered adipocyte function and mitochondrial toxicity, have been shown to be central to the development of HALS. The adipocyte, therefore, represents a plausible target for treatment. Pharmacological and surgical treatment interventions have shown effect. However, their use is associated with numerous adverse effects and complications. Targeted lifestyle interventions may provide a useful alternative for managing HALS owing to their safety and tolerability. A Mediterranean-style diet has been found to be effective in improving the systemic parameters of HALS. Furthermore, the effects of n-3 PUFA supplementation are encouraging and future randomised controlled trials investigating the beneficial effects of n-3 PUFA in HALS are justified.

Abstract
Effective highly active antiretroviral therapy (HAART) for human immunodeficiency virus-1 (HIV) infection has led to marked improvement in life-expectancy for those infected with HIV. Despite reductions in the incidence of AIDS with effective treatment, patients continue to experience considerable morbidity and mortality from non-AIDS illness such as premature cardiovascular disease, liver failure and renal failure. These morbidities, particularly premature cardiovascular disease, are thought to be related to a combination of the effects of an ageing HIV-infected population coupled with long-term effects of HIV infection and antiretroviral therapy (ART). One of the principle drivers behind the well documented increase in the risk of cardiovascular disease in HIV-infected patients is dyslipidemia. This review will focus on the clinical presentation of HIV and ART-associated dyslipidemia, what is known of its patho-physiology, including associations with use of specific antiretroviral medications, and suggest screening and management strategies.

Abstract
To review and synthesize the available scientific evidence on the relationship between dietary intake and dyslipidemias in HIV-infected patients in combination antiretroviral therapy (ART). A systematic review of literature was carried out. Original and published studies were investigated and two categories of dietary exposure were considered: energy and nutrient intake, and consumption of a test diet. A narrative review of included studies was conducted. The findings were summarized according to category of metabolic outcomes (effect on total cholesterol and LDL-c, effect on HDL-c and effect on triglycerides). Twenty original studies were included in this review, being 13 clinical trials and 7 observational studies. Omega-3 fatty acid supplementation led to a significant decrease in triglycerides. There was very little evidence on the effectiveness of dietary interventions for the prevention and control of dyslipidemias in HIV-infected patients receiving ART.

Abstract
Infection caused by HIV and malnutrition have a complex interaction and often coexist geographically. Malnutrition has synergistic immune effects and HIV affects nutritional status. HIV care and treatment programs are compelled to confront this dual burden to optimize HIV outcomes. In this article, we review the published literature concerning intervention studies in adults and children and the effect of food prices on HIV treatment programs. While the evidence base is relatively incomplete for specific macronutrient interventions in the context of HIV treatment, it is clear that a new standard of care is needed, guided by experience, rationale, and existing data, in which malnourished patients may easily access nutritional therapies within HIV treatment. From this clinical foundation, we may both treat patients and evaluate novel therapies. Some HIV care and treatment programs provide food-based supplements; however, rising food costs and economic instability may jeopardize the success of these programs. HIV treatment programs may struggle to meet the needs of patients with potential increased rates of malnutrition and food insecurity in the setting of high food prices.

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 <or= 0.001) in the intervention group. At 3 wk, the insulin area under the curve decreased but not significantly. 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.

Abstract
Compared with healthy controls, HIV patients already have abnormal lipoprotein concentrations before the initiation of highly active antiretroviral therapy (HAART), which worsen with the therapy. HAART-associated dyslipidaemia features fundamental proatherogenic changes such as increased plasma triglycerides (TGs), increased total cholesterol and low-density lipoprotein cholesterol as well as decreased high-density lipoprotein cholesterol (HDL-C). The current guidelines for managing HIV-associated dyslipidaemia recommend diet and exercise counselling, alteration of HAART regimen or addition of lipid-lowering medications such as statins, fibrates and omega-3 (OM-3) fatty acids. Given that cardiovascular risk significantly increases with elevated lipid levels, selecting a drug to manage dyslipidaemia is particularly important. A case is described of an HIV patient who had severe hypertriglyceridaemia and bad metabolic parameters treated with rosuvastatin and OM-3 fatty acids. So we obtained a more marked reduction of TG levels than has never been described before in the literature, associated with a significant increase in HDL-C levels.

Abstract
Since the introduction of HAART, there was a remarkably change in the natural history of HIV disease, leading to a notable extension of life expectancy, although prolonged metabolic imbalances could significantly act on the longterm prognosis and outcome of HIV-infected persons, and there is an increasing concern about the cardiovascular risk in this population. Current recommendations suggest that HIV-infected perons undergo evaluation and treatment on the basis of the Third National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (NCEP ATP III) guidelines for dyslipidemia, with particular attention to potential drug interactions with antiretroviral agents and maintenance of virologic control of HIV infection. While a hypolipidemic diet and physical activity may certainly improve dyslipidemia, pharmacological treatment becomes indispensable when serum lipid are excessively high for a long time or the patient has a high cardiovascular risk, since the suspension or change of an effective antiretroviral therapy is not recommended. Moreover, the choice of a hypolipidemic drug is often a reason of concern, since expected drug-drug interactions (especially with antiretroviral agents), toxicity, intolerance, effects on concurrent HIV-related disease and decrease patient adherence to multiple pharmacological regimens must be carefully evaluated. Often the lipid goals of patients in this group are not achieved by the therapy recommended in the current lipid guidelines and in this article we describe other possibilities to treat lipid disorders in HIV-infected persons, like rosuvastatin, ezetimibe and fish oil.

Abstract
PURPOSE OF REVIEW The recent availability of a concentrated prescription omega-3 fatty acid preparation provides physicians with an additional anti-dyslipidemic agent at a time when limitations of statin therapy in dyslipidemic high-risk patients are recognized. This review examines the evidence supporting the use of omega-3 fatty acid treatment in dyslipidemic states. RECENT FINDINGS There is now considerable evidence that omega-3 fatty acid treatment at the prescription strength of 4 g/day effectively and safely lowers triglyceride levels and increases low-density lipoprotein size, as well as affecting high-density lipoprotein metabolism. Similar effects have been noted in patients treated with statins, and add-on prescription omega-3 fatty acid therapy significantly increases the proportion of statin-treated dyslipidemic patients reaching their non-high-density lipoprotein cholesterol goals. In addition to past studies showing a cardioprotective effect of low-dose omega-3 fatty acid treatment against sudden death, a recent controlled clinical trial showed that 1.8 g of omega-3 fatty acid in statin-treated patients reduced major coronary events by 19% compared with statin plus placebo treatment. SUMMARY Omega-3 fatty acid treatment should be considered in patients with severe hypertriglyceridemia as well as in high-risk patients with an atherogenic lipoprotein phenotype.

Abstract
Background The use of combination antiretroviral therapy (cART) has improved the prognosis of HIV infection, but it has also been linked to a spectrum of body composition changes and metabolic alterations known as the lipodystrophy syndrome. Nutritional status could influence body composition changes. Methods We performed a systematic search of published peer-reviewed data on the effects of diet, nutrition support and exercise on body composition and metabolic complications in patients receiving cART. Results Few controlled studies, most of them with small sample size, were found. Oral nutritional support increases protein and energy intake, and results in body weight and fat mass gains. Resistance exercise, with or without an aerobic component, increases lean mass and can improve insulin resistance. Low-fat diets or exercise can result in loss of fat mass, and they should be used with caution in subjects with lipoatrophy. Conclusions Nutritional support and exercise result in small but significant body composition changes and can be used as complementary interventions. There is a need for further research on nutritional interventions in HIV-infected patients receiving cART.

Abstract
To assess the evolution of triglyceride (TG) levels in HIV-infected patients receiving stable potent antiretroviral therapy treated with N-3 polyunsaturated fatty acids (PUFAs), a prospective double-blind randomized design for a reliable assessment of TG evolution was performed. One hundred twenty-two patients with TG levels >2 g/L and < or =10 g/L after a 4-week diet (baseline TG: 4.5 +/- 1.9 g/L) were randomized for 8 weeks to N-3 PUFAs (2 capsules containing 1 g of fish oil 3 times daily, n = 60), or placebo (1 g of paraffin oil capsules, n = 62). An 8-week open-label phase of N-3 PUFAs followed. Evaluation criteria were TG percent change at week 8, percentage of responders (normalization or > or =20% TG decrease), and safety issues. Ten patients with baseline TG levels >10 g/L were not randomized and received N-3 PUFAs as open treatment. The difference (PUFA - placebo) in TG percent change at week 8 was -24.6% (range: -40.9% to -8.4%; P = 0.0033), the median was -25.5% in the PUFA group versus 1% in the placebo group, and mean TG levels at week 8 were 3.4 +/- 1.8 g/L and 4.8 +/- 3.1 g/L, respectively. TG levels were normalized in 22.4% (PUFA) versus 6.5% (placebo) of patients (P = 0.013) with a > or =20% reduction in 58.6% (PUFA) versus 33.9% (placebo) of patients (P = 0.007). Under the open-label phase of N-3 PUFAs, the decrease in TG levels was sustained at week 16 for patients in the PUFA group (mean TG: 3.4 +/- 1.7 g/L), whereas a 21.2% decrease in TG levels occurred for patients in the placebo group (mean TG: 3.3 +/- 1.4 g/L). No significant differences were observed between groups in the occurrence of adverse events. The median TG change at week 8 was -43.6% (range: Q1-Q3; 95% CI: -66.5% to -4.6%) for patients with baseline TG levels >10 g/L. The difference in mean total cholesterol between groups (PUFA - placebo) at week 8 was -8.5% (P = 0.0117). This study demonstrated the efficacy of PUFAs to lower elevated TG levels in treated HIV-infected hypertriglyceridemic patients. N-3 PUFAs have a good safety profile.

Abstract
Accumulating evidence suggests that HIV-infected individuals have an increased risk of cardiovascular events. This risk seems to be at least partially mediated by dyslipidaemia, which is related to the use of highly active antiretroviral therapy (HAART). As HIV-infected individuals live longer due to HAART, their cardiovascular risk will invariably increase. Because HAART is likely to be used indefinitely, HAART-related dyslipidaemia has emerged as a major cardiovascular concern. This article summarises the evaluation of dyslipidaemia and cardiovascular risk in HIV-infected individuals, the potential pathophysiological and genetic mechanisms involved in HAART-related dyslipidaemia and the current treatment approaches. In general, dyslipidaemia is evaluated and treated as in HIV-negative persons. The first step is cardiovascular risk assessment and the determination of target lipid levels. A healthier lifestyle and, in particular, smoking cessation should be promoted. Lowering levels of low-density lipoprotein cholesterol (or, in the setting of significant hypertriglyceridaemia, non-high-density lipoprotein cholesterol) is the primary target of intervention. Switching HAART to a more lipid-favourable regimen should be considered if this does not jeopardise virological control. Many patients will need lipid-lowering drug therapy. Appropriate low-density lipoprotein cholesterol target levels may be more difficult to reach than in the HIV-negative population, and the potential for drug interactions when using lipid-lowering agents together with HAART needs to be considered. The identification of HAART strategies with no or minimal metabolic toxicity, and the identification of the safest and most efficacious lipid-lowering therapies for HIV-infected individuals with dyslipidaemia are important research goals.
