Efeito da fibra solúvel sobre a hipertrigliceridemia e perfil imunológico de indivíduos HIV positivo em uso de terapia anti-retroviral de alta atividade

Abstract

The advent of highly active antiretroviral therapy (HAART), since 1996, represented a profound impact on the natural history of HIV-infection by promoting important and sustainable viral replication suppression and increasing survival and quality of life among seropositive patients. Nonetheless, antiretroviral therapy has been observed to be accompanied by metabolic alterations such as dyslipidemia, especially hypertriglyceridemia, insulin resistance, hyperglycemia and lipodystrophy (body fat redistribution). Epidemiological studies have demonstrated a correlation between high triglyceride (TG) levels and higher incidence of coronary artery disease (CAD). Some investigators suggest dietary intervention as part of hyperlipidemia treatment, including an increase in soluble fiber intake (10-25g/day). Whereas some studies have demonstrated that both cholesterol and serum triglyceride levels decrease with the use of food fiber, others have shown just a serum triglyceride decrease, and others failed to observe any alteration in lipid metabolism. The purpose of this study was to assess the effect of soluble fiber® (partially hydrolyzed guar gum) supplementation on hypertriglyceridemia and immune profile in HIV-positive individuals on HAART. Nineteen HIV-positive individuals with hypertriglyceridemia (serum levels 150 to < 500 mg/dL) were studied. Of these individuals, 63,16% were males and 36,84% females, with mean age of 43,52 ± 9,22 years. These individuals had been on the same HAART regimen for at least 6 months, had no change in therapy during the study and received 20g/day of soluble fiber for four months at pre-established times. Clinical-nutritional, biochemical (total proteins, albumin, globulin, total cholesterol, LDL-c, HDL-c, TG, TG/HDL-c and LDL-c/HDL-c)... (Complete abstract click electronic access below)

O advento da utilização da terapia antiretroviral de alta atividade (HAART), a partir de 1996, representou um profundo impacto na história natural da infecção pelo HIV, promovendo uma importante e sustentada supressão na replicação viral, elevando a sobrevida e a qualidade de vida dos pacientes soropositivos. No entanto, gradualmente, foi se observando que a terapia antiretroviral é acompanhada de alterações metabólicas, como dislipidemia, principalmente hipertrigliceridemia, resistência insulínica, hiperglicemia e lipodistrofia, isto é, redistribuição da gordura corporal. Ensaios epidemiológicos demonstram correlação entre os níveis elevados de triglicerídeos (TG) e maior incidência de doença arterial coronariana (DAC). Autores sugerem a intervenção dietética como parte do tratamento da hiperlipidemia, incluindo aumento da ingestão de fibra solúvel (10g-25g/dia). Há estudos demonstrando que tanto o colesterol quanto os triglicerídeos séricos diminuem com a utilização de fibra alimentar. Alguns observaram redução apenas nos níveis séricos de triglicerídeos, enquanto que outros não verificaram alteração no metabolismo lipídico. O objetivo do presente estudo foi avaliar o efeito da fibra solúvel (goma guar parcialmente hidrolisada) suplementar sobre a hipertrigliceridemia e o perfil imunológico de indivíduos HIV positivo em tratamento com HAART. Foram estudados 19 pacientes HIV positivo com hipertrigliceridemia (níveis séricos ³ 150 a < 500mg/dL), sendo 63,16% do sexo masculino e 36,84% feminino, com média de idade de 43,52 ± 9,22 anos. Esses indivíduos utilizavam o mesmo esquema HAART há pelo menos seis meses, sem mudança da terapia durante o estudo e receberam 20g de fibra solúvel por dia, durante quatro meses...
