ABSTRACT
BACKGROUND:
Environmental and genetic factors (viruses, toxins and diet) are involved in the aetiology of type 1 diabetes. Among the dietary factors, the role of breast feeding and exposure to cow's milk proteins deserve special attention.AIM:
To determine the anti-BSA-IgG levels in type 1 diabetic children and to analyse the possible association with breast feeding duration, exposure to cow's milk and beta pancreatic auto-antibodies. PATIENTS ANDMETHODS:
Blood samples were collected from 161 diabetic children and 144 controls to measure anti-BSA-IgG level, GAD65, IA-2 and ICA autoantibodies. All children answered a questionnaire about dietary habits during infancy.RESULTS:
anti-BSA-IgG was positive (using a cut off point of 25.6 ng/ml) in 98 per cent of diabetic children and 0 per cent of the control population. The length of breast feeding or early exposure to cow's milk did not influence the concentration of anti-BSA-IgG. Positive BSA titers did not increase the beta pancreatic reactivity (ICA+, GAD+, IA2+).CONCLUSIONS:
Our data confirm the high frequency of anti-BSA-IgG among diabetic children. However, a specific role in the immunological process of type 1 diabetes cannot be attributed to this protein.
