目的:测定慢性腹泻患儿血清食物不耐受特异性IgG抗体并进行脱敏治疗,观察脱敏治疗后患儿腹泻缓解情况。方法:采用血清特异性IgG抗体测定法检测59例慢性腹泻患儿血清食物不耐受特异性IgG抗体。结果:59例慢性腹泻患儿食物不耐受特异性IgG抗体检测阳性率达93.22%。59例慢性腹泻患儿经脱敏治疗1个月和3个月后总有效率分别为74.55%和82.69%。结论:食物不耐受可能为小儿慢性腹泻的原因之一,慢性腹泻患儿有必要进行血清食物不耐受特异性IgG抗体测定并进行脱敏治疗。
Objective: To determine the serum food intolerance of specific IgG antibodies in children with chronic diarrhea and desensitization therapy to observe the relief of diarrhea in children with desensitization treatment. Methods: Serum food-specific IgG antibodies were detected in 59 children with chronic diarrhea using serum-specific IgG antibody assay. Results: The positive rate of food-intolerance-specific IgG antibodies in 59 children with chronic diarrhea was 93.22%. The total effective rate of children with chronic diarrhea was 74.55% and 82.69% respectively after desensitization treatment for 1 month and 3 months. Conclusion: Food intolerance may be one of the causes of chronic diarrhea in children. Chronic diarrhea is necessary for serum food intolerance specific IgG antibody testing and desensitization.
