Abstract:
Objective To investigate the distribution of serum specific IgG antibodies against food in children with autism spectrum disorders(ASD),and provide experimental evidence for improving gastrointestinal symptoms of ASD children.Methods A retrospec-tive study was conducted on 411 children with ASD visited the Department of Psychology and Behavior of Hebei Children's Hospital from January 2021 to December 2022.Additionally,631 healthy children who underwent physical examination during the same period were collected as the healthy control group.Their venous blood samples were collected,and ELISA was used to detect the levels of 14 kinds of serum specific IgG antibodies against food.The distribution characteristics of food intolerance in children with different genders and ages were investigated.Results The total positive rate of specific IgG antibodies against food in children with ASD reached 91.84%(405/441).The top 3 positive rates of specific IgG antibodies were against egg(71.89%),milk(56.70%),and wheat(56.02%),respectively,which were significantly higher than those in the healthy control group(χ2=42.81,27.48,and 26.88,re-spectively,P<0.05).The comparative results of gender composition showed that the positive rate of specific IgG antibody against rice in female ASD children(15.96%)was significantly higher than that in male ASD children(4.90%,χ2=11.84,P<0.05).The posi-tive rates of specific IgG antibodies against egg and wheat in male and female ASD children were significantly higher than those in the healthy control group(χ2=19.44 and 4.42 for males,χ2=4.66 and 10.93 for females,P<0.05).The positive rate of specific IgG anti-body against milk in male ASD children was significantly higher than that in the healthy control group(χ2=12.62,P<0.05),while those against soybean and rice in female ASD children were also significantly higher than that in the healthy control group(χ2=7.00 and 5.42,P<0.05).There were significant differences in the positive rates of food intolerance to milk and soybean in ASD children with different ages(χ2=13.74 and 9.70,P<0.05)and they decreased with age.The positive rates of specific IgG antibody against wheat in ASD children aged 2-3 and 4-6 years were significantly higher than those in the healthy control group(χ2=5.78 and 4.55,P<0.05).The positive rate of specific IgG antibody against milk in ASD children aged 4-6 years was significantly higher than that in the healthy control group(χ2=7.57,P<0.05).Conclusion The highest positive rate of specific IgG antibodies against food in ASD chil-dren is against egg,which is not related to the patient's gender.Next are milk and wheat.The gastrointestinal issues and related food intolerance should be taken into account in the management of patients with ASD.
