Abstract HIV-infected individuals on chronic use of highly active antiretroviral therapy (HAART) are more likely to develop adipose tissue and metabolic disorders, such as lipodystrophy (LD) and metabolic syndrome (MetS). The development of these phenotypes is known to be multifactorial. Thus, variants in genes implicated in adipogenesis and lipid metabolism may increase susceptibility to LD and MetS. Sirtuin 1 (SIRT1) may influence the outcome of these disturbances due to its role in the regulation of transcription factors involved in energy regulation. Therefore, we genotyped four polymorphisms located in SIRT1 (rs2273773 T>C, rs12413112 G>A, rs7895833 A>G, rs12049646 T>C) in 832 HIV-infected patients receiving HAART by real-time polymerase chain reaction. The prevalence of LD was 55.8% and MetS was 35.3%. Lipoatrophy was the most prevalent subtype in all samples (38.0%) and showed significant difference between white and non-white individuals (P = 0.002). None of the genetic variants investigated in SIRT1 was associated with LD and MetS. White individuals and those in longer time of HAART use were more likely to develop LD. We concluded that these SIRT1 polymorphisms are not predictive factors to the development of lipodystrophy and metabolic syndrome in HIV-infected individuals from Brazil.

O objetivo do estudo foi investigar o consumo de álcool e verificar sua associação com escolaridade, renda e excesso de peso em uma amostra de mulheres. Trata-se de um estudo transversal com 317 mulheres. Aplicou-se um questionário padronizado e pré-codificado para determinar a quantidade, a frequência e o tipo de bebida alcoólica consumida. As mulheres foram classificadas em dois grandes grupos, conforme a quantidade de bebida consumida. O primeiro grupo "Consumo de Álcool", formado por duas subcategorias: (1) mulheres que bebiam no mínimo 10g/dia de etanol; (2) mulheres que referiram não consumir 10g/dia de etanol e as que beberam em algum período da vida ou previamente, mas que o deixaram de fazer. O segundo grupo, "Contato com Álcool", foi composto por três subcategorias: (1) bebedoras (mulheres que bebiam no mínimo 10g/dia de etanol), (2) ex-bebedoras (já beberam regularmente, mas deixaram de consumir a bebida) e (3) não bebedoras. Das investigadas, 30% eram bebedoras e 36,6% se declararam ex-bebedoras. Tinham sobrepeso 39,4% das participantes e 34,3% eram obesas. As investigadas com maior grau de instrução consumiam maior quantidade de álcool, quando comparadas às mulheres com menor escolaridade (analfabetas) que consumam menos (p = 0,010).

The scope of this study was to investigate alcohol consumption and its association with educational level, income and weight in a sample of women. It involved a cross-sectional study with 317 women. A standardized and pre-encoded questionnaire was applied to determine the amount, frequency and type of alcoholic beverage consumed. The women were classified in two large groups according to the number of drinks consumed. The first group "Alcohol Consumption," was comprised of two subcategories: (1) women who drank at least 10g/day of ethanol; (2) women who reported not consuming 10g/day of ethanol, and those who drank at some period of their lives or previously, but no longer did so. The second group, "Contact with Alcohol," was composed of three subcategories: (1) drinkers (women who drank at least 10g/dia of ethanol); (2) former drinkers (women who used to drink regularly, but no longer drink alcohol); and (3) non-drinkers. 30% of the women investigated were drinkers, and 36.6% reported they were former drinkers. 39.4% of the total sample was overweight and 34.3% obese. Women with higher educational levels were found to consume a larger amount of alcohol when compared to women with less education (illiterate) who consume less (p = 0.010).

Metabolic complications continue to play a major role in the management of HIV infection. Dyslipidemia associated with HIV infection and with the use of combined antiretroviral therapy includes elevations in triglycerides, reduced high-density cholesterol, and variable increases in low-density and total cholesterol. The association between dyslipidemia and specific antiretroviral agents has been underscored. Multiple pathogenic mechanisms by which HIV and antiretroviral agents lead to dyslipidemia have been hypothesized, but they are still controversial. The potential clinical and pathological consequences of HIV-associated hyperlipidemia are not completely known, but several studies reported an increased risk of coronary artery disease in HIV-positive individuals receiving combined antiretroviral therapy. HIV-infected persons who have hyperlipidemia should be managed similarly to those without HIV infection in accordance with the National Cholesterol Education Program. Life style changes are the primary target. Statins and fibrates and/or modification in antiretroviral therapy are possible approaches to this problem.
