Links between autism and allergy

Methods 251 individuals participated in this study: 1. 42 with autism without allergies 2. 42 women (mothers of the autistic patients) without autism 3. 104 allergic patients without autism 4. 63 normal health controls The ASST was performed injecting intradermically 0,05 ml of the each own serum in the volar surface of the forearm. Saline was used as a negative control. After 15 minutes the weals were measured. A result was considered positive when the weal diameter with the serum (this weal was a result of the presence of anti-IgE and/ or anti-IgE receptor antibodies) was at least 3 mms greater than that one measured with the saline. Statistical analysis: chi-squared and Fisher’s methods were used to evaluate the results.
