Ready-to-use therapeutic food (RUTF) is the preferred treatment for uncomplicated severe acute malnutrition. It contains large amounts of linoleic acid and little α-linolenic acid, which may reduce the availability of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) to the recovering child. A novel high-oleic RUTF (HO-RUTF) was developed with less linoleic acid to determine its effect on DHA and EPA status.
We conducted a prospective, randomized, double-blind clinical effectiveness trial treating rural Malawian children with severe acute malnutrition. Children were treated with either HO-RUTF or standard RUTF. Plasma phospholipid fatty acid status was measured on enrollment and after 4 weeks and compared between the 2 intervention groups.
Among the 141 children enrolled, 48 of 71 receiving HO-RUTF and 50 of 70 receiving RUTF recovered. Plasma phospholipid samples were analyzed from 43 children consuming HO-RUTF and 35 children consuming RUTF. The change in DHA content during the first 4 weeks was +4% and -25% in the HO-RUTF and RUTF groups, respectively (P = 0.04). For EPA, the change in content was 63% and -24% in the HO-RUTF and RUTF groups, respectively (P < 0.001). For arachidonic acid, the change in content was -3% and 13% in the HO-RUTF and RUTF groups, respectively (P < 0.009).
The changes in DHA and EPA seen in the children treated with HO-RUTF warrant further investigation because they suggest that HO-RUTF support improved polyunsaturated fatty acid status, necessary for neural development and recovery.
即食治疗性食品(RUTF)是治疗无并发症的重度急性营养不良的首选疗法。它含有大量亚油酸,而α-亚麻酸含量很少,这可能会降低康复期儿童体内二十二碳六烯酸(DHA)和二十碳五烯酸(EPA)的可利用性。一种新型的高油酸RUTF(HO-RUTF)被研发出来,其亚油酸含量较低,以确定其对DHA和EPA状态的影响。
我们开展了一项前瞻性、随机、双盲临床疗效试验,治疗马拉维农村地区患有重度急性营养不良的儿童。儿童分别接受HO-RUTF或标准RUTF治疗。在入组时和4周后测量血浆磷脂脂肪酸状态,并在两个干预组之间进行比较。
在141名入组儿童中,71名接受HO-RUTF治疗的儿童中有48名康复,70名接受RUTF治疗的儿童中有50名康复。对43名食用HO-RUTF的儿童和35名食用RUTF的儿童的血浆磷脂样本进行了分析。在HO-RUTF组和RUTF组中,前4周DHA含量的变化分别为+4%和-25%(P = 0.04)。对于EPA,HO-RUTF组和RUTF组中含量的变化分别为63%和-24%(P < 0.001)。对于花生四烯酸,HO-RUTF组和RUTF组中含量的变化分别为-3%和13%(P < 0.009)。
接受HO-RUTF治疗的儿童中DHA和EPA的变化值得进一步研究,因为这表明HO-RUTF有助于改善多不饱和脂肪酸状态,而这对神经发育和康复是必需的。
