ABSTRACT

The importance of the metabolic disorders and their impact on patients with HIV infection requires an individualized study and continuous updating. HIV patients have the same cardiovascular risk factors as the general population. The HIV infection per se increases the cardiovascular risk, and metabolic disorders caused by some antiretroviral drugs are added risk factors. For this reason, the choice of drugs with a good metabolic profile is essential. The most common metabolic disorders of HIV infected-patients (insulin resistance, diabetes, hyperlipidemia or osteopenia), as well as other factors of cardiovascular risk, such as hypertension, should also be dealt with according to guidelines similar to the general population, as well as insisting on steps to healthier lifestyles. The aim of this document is to provide a query tool for all professionals who treat HIV-patients and who may present or display any metabolic disorders listed in this document.

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

Lipodystrophy (lipo) and metabolic derangements associated with an increased cardiovascular risk are observed frequently in human immunodeficiency virus (HIV)-infected patients who receive antiretroviral treatment (ART). The objective of the study was to provide detailed biochemical information about metabolic syndrome in this condition. One hundred forty-six HIV-infected male and female patients on ART for more than 6 months were compared with 156 body mass index (BMI)-matched healthy subjects. Lipodystrophy was diagnosed upon patient and physician concordance. Metabolic syndrome was defined according to the Adult Treatment Panel III criteria. Plasma adiponectin (AD) and leptin were measured by radioimmunoassay. Insulin resistance (IR) was assessed by the homeostasis model assessment (HOMA). The prevalence of metabolic syndrome was higher in HIV-infected patients on ART than in non-HIV-infected healthy controls (15.8% vs 3.2%; P < .001). Patients with metabolic syndrome are older (44.6 +/- 6 vs 39.8 +/- 8 years; P = .004), have an increased BMI (24.9 +/- 3.8 vs 22.9 +/- 9.8 kg/m(2); P = .01), present with a reduced AD-to-leptin ratio log(10) (-0.19 +/- 0.4 vs 0.5 +/- 0.4; P = .04), and show increased IR (HOMA, 5.6 +/- 2.7 vs 3.8 +/- 2.2; P = .001; plasma fasting insulin, 22.9 +/- 9.8 vs 16.6 +/- 9.7 ng/mL; P < .001). In multivariate analysis, the diagnosis of lipo and HOMA were independently and significantly related to metabolic syndrome. In conclusion, the prevalence of metabolic syndrome is significantly increased in HIV-infected patients on ART and its presence is associated with lipo, increased age and BMI, IR, and a reduced plasma AD-to-leptin ratio.

ABSTRACT

BACKGROUND: Metabolic disturbances and fat maldistribution are main features of the antiretroviral-related lipodystrophy syndrome (LDS). Different phenotypes of fat distribution abnormalities can be observed: fat loss, fat accumulation, or a mixed pattern. In patients with predominant loss of fat, the roles of leptin, lipids, and glucose homeostasis disturbances have not yet been clearly established. METHODS: The study comprised 34 HIV-infected male patients receiving antiretroviral treatment that included protease inhibitors. A lipoatrophic phenotype, defined as fat loss in face or extremities, both normal weight and waist:hip ratio, and absence of fat accumulation elsewhere, was present in all cases. Fat distribution disturbances were confirmed by abdominal and midthigh computed tomography-calculated adipose tissue content. Fasting plasma glucose, insulin, proinsulin, total leptin, testosterone, and lipid profiles were measured. After 2 hours, 75-g oral glucose tolerance test (OGTT), glucose, insulin, and proinsulin levels were also obtained. Insulin resistance was calculated using the homeostasis model assessment for insulin resistance (HOMA-r) method. Both healthy study subjects ( n = 385) and antiretroviral-naive HIV-positive patients ( n = 13) were used as controls. RESULTS: Of these LDS patients, 5.8% showed diagnostic criteria for diabetes and 17.8% for impaired glucose tolerance. A lipid pattern characterized by high total cholesterol and high low density lipoprotein (LDL) plasma levels, hypertriglyceridemia, and normal high density lipoprotein (HDL) levels was observed. Fasting insulin and 2-hour post OGTT insulin levels, and insulin resistance index were significantly higher in LDS patients than in antiretroviral-naive HIV-positive patients. Plasma leptin levels were significantly lower in lipoatrophic patients than in healthy control individuals. Patients with LDS presented with significant midthigh fat reduction and visceral fat accumulation compared with findings in antiretroviral-naive HIV-positive patients. A significant correlation was found between plasma leptin levels and midthigh fat content. CONCLUSION: Peripheral fat loss in extremities in LDS patients with lipoatrophic phenotype is also associated with low plasma leptin levels, visceral fat accumulation, and metabolic disturbances related to an increased cardiovascular risk. In LDS patients, plasma leptin levels could be a marker of subcutaneous adipose tissue content.
