Value of food-specific IgG antibody detection in children with chronic digestive system diseases

AIM: To explore the value of food-specific IgG antibody detection in children with chronic diseases of the digestive system.

METHODS: One hundred and six children with chronic diseases of the digestive system (experiment group) and 106 children without digestive system disorders (control group) were included in this study. The IgG antibodies against 14 types of food were detected, and the positive rate of serum food-specific IgG antibody detection and feeding patterns in 4 mo after birth between the two groups were compared.

RESULTS: The positive rates of antibodies against eggs (61.32%, 18.87%) and milk (43.40%, 11.32%) were relatively high in the two groups compared with those against other food. The positive rates of antibodies against milk, eggs and soybean in the experiment group were significantly higher than those in the control group (43.40% vs 11.32%, 61.32% vs 18.87%, 11.32% vs 0.00%, P < 0.05). The percentages of subjects who were positive for antibodies against 2 or 3 kinds of food as well as the total positive rate in the experiment group were significantly higher than those in the control group (34.91% vs 13.21%, 15.09% vs 4.72%, 85.85% vs 49.06%, P < 0.05). The breast-feeding rate in 4 months after birth in the experiment group was significantly lower than that in the control group (43.40% vs 76.42%, P < 0.05). The rates of artificial feeding and partial breastfeeding in the experiment group were significantly higher than those in the control group (8.49% vs 1.89%, 48.11% vs 21.70%, P < 0.05).

CONCLUSION: Food-specific IgG detection can help identify chronic diseases of the digestive system caused by food. The antibodies against milk and eggs are the most common. Early feeding way is an important factor responsible for food intolerance.
