摘 要:【摘要】目的观察谷氨酰胺(GLN)强化的肠内营养(EN)干预对获得性免疫缺陷综合征(AIDS)患儿营养状况和淋巴细胞免疫功能的影响。方法将符合入选标准的58例AIDS患儿采用随机数字表法分为观察组(GLN强化EN组,30例)与对照组(常规EN组,28例)。干预前和干预第28天分别检测2组患儿营养相关指标、细胞免疫指标及血清GLN水平变化。结果干预第28天观察组患儿体质量均较对照组明显升高[(29.9±7.4)k比(28.0±8.3)kg,t=3.216,P=0.006]、体质量指数[(17.8±1.9)kg/m2比(16.9±1.9)kg/m2,t=3.339,P=0.002]、总淋巴细胞计数[(2.81±0.25)×109/L比(2.53±0.24)×109/L,江3.064,P=0.004]、血清GLN水平[(7.2±2.1)μmol/L比(5.5±1.2)μmol/L,t=2.496,P=0.012];观察组清蛋白[(40.5±3.1)g/L比(38.6±2.1)g/L,t=3.82,P=0.001]、前清蛋白[(182.0±38.6)mg/L比(175.1±40.0)mg/L,t=2.917,P=0.007]、血红蛋白[(115.7±8.5)g/L比(104.8±11.5)g/L,t=3.022,P=0.005I、[CD4+%(39.0±7.5)%比(35.3±9.9)%,t=3.138,P=0.004]、CD4+/CD8+比值[(1.6±0.8)比(1.2±0.6),t=3.198,P=0.001]也明显高于对照组;观察组胃肠道并发症的发生率较对照组低(16.7%比32.1%,x2=11.250,P=0.001)。结论GLN强化的EN干预能改善AIDS患儿营养状况,提高其淋巴细胞的免疫功能,减少胃肠道并发症,降低新发感染率,缩短患儿住院时间,对改善AIDS患儿预后有积极的作用,值得临床推广应用。Objective To investigate the effect of glutamine(GLN) fortifying enteral nutrition (EN) interven- tion on nutrition status and lymphocytes-mediated immune function in children with acquired immune deficiency syn- drome (AIDS). Methods According to random number table, the 58 cases of AIDS patients conformed to the standard were divided into observation group (GLN improved group ,30 cases) and control group (conventional EN, 28 cases). Nutrition related index,index of cellular immunity and serum GLN concentration change of the 2 groups were detected before intervention and after intervention for 28 days. Results Body mass in the observation group after intervention for 28 days[(29.9 ±7.4) kgvs(28.0±8.3) kg,t=3.216,P=0.0061,body mass index [(17.8 ±1.9) kg/m2 vs ( 16. 9 ± 1.9) kg/m2,t = 3. 339, P = 0. 002 ], total lymphocyte count [ (2. 81 ± 0. 25 ) ×109/L vs (2. 53 ± 0. 24) x 109/L,t = 3. 064 ,P =0. 0041 , serum level of GLN [ ( 7.2 ± 2. 1 ) p.mol/L vs ( 5.5 ± 1.2) μmol/L, t = 2. 496, P = 0. 012] were notably increased compared with those of control group. In observation group albumin [ (40. 5 ± 3. 1 ) g/L vs ( 38.6 ± 2. 1 ) g/L, t = 3.82, P = 0. 001 ], pre-albumin [ ( 182. 0± 38.6) mg/L vs ( 175.1 ± 40. 0 ) mg/L, t = 2. 917, P=0.007],hemoglobin [(115.7 ±8.5) g/Lvs (104.8 ±11.5) g/L,t=3.022,P=0.005],CD4±% (39.0± 7.5)% vs (35.3 ±9. 9)% ,t =3. 138,P =0. 004] ,CD±/CD8 ± ratio[ (1.6 ±0. 8) vs (1.2 ±0. 6) ,t = 3. 198,P = 0. 001 ] were significantly higher than those of the control group. Incidence rate of gastrointestinal complications of the observation group were lower than that of the control group( 16. 7% vs 32. 1% ,X2 = 11.25, P = 0. 001 ). Conclusions Enhanced GLN EN intervention can improve nutritional status in AIDS children, raise the level of lymphocyte immu- nity, reduce gastrointestinal complications and new infections, shorten hospitalization time, and improve the prognosis of children wit
