本文对84例二、三度营养不良合并腹泻婴幼儿进行腹泻病原学、免疫功能、体锌、木糖吸收排泄试验和胰腺外分泌功能检测,6例尸检。提示营养不良合并腹泻与肠道感染、缺锌、胰腺外分泌功能下降和肠上皮细胞器官特异性营养不良有关。在诊治中应区别感染性或非感染性腹泻,合理应用抗生素。木糖吸收排泄试验和乳果糖甘露醇通透性试验是非损伤性小肠粘膜结构和功能检测方法,可用于预测营养不良和腹泻并指导诊治。
In this paper, 84 cases of second and third degree malnutrition with diarrhea in infants and young children diarrhea etiology, immune function, body zinc, xylose absorption excretion test and pancreatic exocrine function test, 6 cases of autopsy. Prompt malnutrition associated with diarrhea and intestinal infections, zinc deficiency, decreased pancreatic exocrine function and intestinal specific organ dystrophy. In the diagnosis and treatment should distinguish between infectious or non-infectious diarrhea, rational use of antibiotics. Xylose Absorption Excretion Test and Lactulose Mannitol Permeability Test are non-invasive small intestinal mucosa structure and function test method that can be used to predict malnutrition and diarrhea and guide the diagnosis and treatment.
