作者观察54例对食物变态反应(FA)小儿。男23例,女31例。5～7岁22例,8～12岁24例,12岁以上8例患儿具有典型的腹痛和消化障碍症状,有对食物不耐受及患皮肤病史。全部小儿现均有局限性神经皮炎或异位性皮炎。不耐受食品为纯牛乳,豆制品、蛋、柑桔、草莓和巧克力糖等。服用利胆剂以后疼痛见少仅为26%。1/3小儿在吃食物后立刻有呕吐、肠鸣症状,l/2有嗳气,72%便秘或轻微腹泻。临床观察FA常伴有变态反应性皮肤病和消化道病变。对FA小儿的小肠功能状态做了检查,测定尿排泄D-木糖含量,结果同对照组相比没有区别(P>0.05)。测定对乳糖耐受性标准试验,结果有50%观察指标明显低于对照组。为此,又据血总IgE水平将
The authors observed 54 patients with food allergy (FA) in children. There were 23 males and 31 females. 22 cases of 5 to 7 years old, 24 cases of 8 to 12 years old, 8 cases of children over 12 years old with typical symptoms of abdominal pain and digestive disorders, with food intolerance and skin history.

Clinical observation of FA often accompanied by allergic dermatosis and gastrointestinal lesions. Small intestine in children with functional status of FA was examined to determine urinary excretion of D-xylose content, the results were no difference with the control group (P> 0.05). Standard test for lactose tolerance, the results showed that 50% of the observed index was significantly lower than the control group. To this end, blood total IgE levels will be
