HIV/AIDS is generally associated with dyslipidemia and oxidative imbalance, which are caused by the infection itself and by antiretroviral therapy (ART). The flavonoids, found in cocoa and yerba mate, have antioxidant and hypolipidemic properties. The aim of this study was to evaluate the effects of the consumption of dark chocolate and mate tea on the lipid profiles of individuals with HIV/AIDS who are undergoing ART.
A randomized, double-blind, placebo-controlled crossover clinical trial was conducted with 92 patients receiving ART for ≥6 mo and with viral suppression. The participants were randomized to receive either 65 g of chocolate (with 2148 mg polyphenols) or placebo chocolate (without polyphenols) or 3 g of mate tea (with 107 mg total phenols and 84.24 mg chlorogenic acid) or placebo mate (without polyphenols) for 15 d each, separated by a washout period of 15 d. The lipid profile, including determination of electronegative low-density lipoprotein, was determined after each intervention. The data were analyzed by analysis of variance using the pkcross procedure of the Stata 11.0 software.
Analysis of variance revealed a significant overall difference in mean high-density lipoprotein cholesterol (HDL-C) between all supplements (P = 0.047). Using the paired t test, the effect was attributed to the consumption of dark chocolate (P = 0.046). The other parameters investigated were not improved.
The consumption of dark chocolate for 15 d improved HDL-C concentrations of individuals with HIV/AIDS undergoing ART, possibly due to the presence of fatty acids (stearic acid), polyphenols, and theobromine. This fact is important for the cardiovascular protection of these individuals.
艾滋病毒/艾滋病通常与血脂异常和氧化失衡有关,这些问题是由感染本身和抗逆转录病毒疗法(ART)引起的。可可和马黛茶中的类黄酮具有抗氧化和降血脂的特性。本研究旨在评估食用黑巧克力和马黛茶对接受 ART 治疗且病毒得到抑制的艾滋病毒/艾滋病患者血脂谱的影响。
采用随机、双盲、安慰剂对照交叉临床试验,纳入 92 名接受 ART 治疗≥6 个月且病毒得到抑制的患者。参与者被随机分为三组,分别接受 65g 巧克力(含 2148mg 多酚)或安慰剂巧克力(不含多酚),或 3g 马黛茶(含总酚 107mg 和绿原酸 84.24mg)或安慰剂马黛茶(不含多酚),每种干预措施持续 15 天,洗脱期为 15 天。在每次干预后,测定血脂谱,包括测定电负性低密度脂蛋白。使用 Stata 11.0 软件的 pkcross 过程分析方差对数据进行分析。
方差分析显示,所有补充剂之间的平均高密度脂蛋白胆固醇(HDL-C)存在显著的总体差异(P=0.047)。使用配对 t 检验,这种影响归因于黑巧克力的消耗(P=0.046)。其他研究参数没有得到改善。
食用黑巧克力 15 天可改善接受 ART 治疗的艾滋病毒/艾滋病患者的 HDL-C 浓度,这可能是由于存在脂肪酸(硬脂酸)、多酚和可可碱。这一事实对这些患者的心血管保护很重要。
