Dietary counseling and oral supplementation have unclear results in preventing the progressive weight loss in human deficiency virus (HIV)-infection. The aim of the study was to compare the progression of nutritional indicators with or without a formula enriched with n-3 fatty acids.
30 HIV patients were enrolled. 15 were randomized to group I (standard formula) and 15 were randomized to group II (formula enriched with n-3 fatty acids). A nutritional evaluation was realized at basal time and at 3 months.
An increase in protein and calories intakes was detected in both. There was a significant increase in n3 fatty acid intake from baseline in group II, without statistical changes in group I. Treatment with both supplements resulted in a significant and sustained increase in weight (4.5% in group I and 5.4%, in group II). This increase was mostly due to fat free mass in group I. In group II it was due to an increase in fat free mass and fat mass.
Oral nutritional supplements for a 3-months period were well tolerated and resulted in body weight gain in HIV-infected patients with previous weight loss.
饮食咨询和口服补充剂在预防人类免疫缺陷病毒 (HIV) 感染患者体重持续下降方面的效果尚不清楚。本研究旨在比较补充富含 n-3 脂肪酸配方与未补充该配方对营养指标进展的影响。
共纳入 30 名 HIV 患者。其中 15 名随机分为 I 组(标准配方),15 名随机分为 II 组(富含 n-3 脂肪酸的配方)。在基线和 3 个月时进行营养评估。
两组患者的蛋白质和热量摄入均增加。与 I 组相比,II 组 n3 脂肪酸摄入量从基线开始显著增加,而 I 组无统计学变化。两种补充剂的治疗均导致体重显著且持续增加(I 组增加 4.5%,II 组增加 5.4%)。这种增加主要归因于 I 组的去脂体重增加。在 II 组中,增加归因于去脂体重和脂肪质量的增加。
口服营养补充剂治疗 3 个月可耐受良好,并可使既往体重减轻的 HIV 感染患者体重增加。
