    Abstract:
    Cow's Milk Protein Intolerance (CMPI) is the most common food intolerance in childhood. The I, III and IV type of the immunological mechanisms are involved in the pathogenesis. Nowadays there are no diagnostic tests with good reliability excluding the IgE-mediated clinical pictures. Recently the evaluation of antibodies (IgA and IgG classes) versus milk proteins has been proposed as reliable test. In order to establish the pattern of antibody response against milk proteins we studied 37 children (17 males and 20 females), aged from 3 months to 6 years, divided as follows: 23 with CMPI of which 16 suffering from gastrointestinal complaints (GI) and 7 from cutaneous ones (CT); 5 children with coeliac disease; 9 normal healthy children without any clinical manifestation. All children at the time of the assessment assuming a diet containing cow's milk proteins. IgA, IgG and IgM antibody classes against cow's milk proteins such as alpha-lactoalbumin (alpha LA), beta-lactoglobulin (beta LG), casein (CAS) and pooled proteins (PPL) were measured using an ELISA method. The results obtained in the various groups were as follows: CMPI-GI group: the percentage of positivity for alpha LA-IgA was 43.8% and alpha LA-IgG 68.7%, for beta LG-IgA was 50% and beta LG-IgG 75%, for CAS-IgA was 43.8% and CAS-IgG 68.7%, for PPL-IgA was 37.5% and PPL-IgG 62.5%. CMPI-CT group: the percentage of positivity for alpha LA-IgA was 42.8% and alpha LA-IgG 57.1%, for beta LG-IgA was 71.4% and beta LG-IgG 42.8%, for CAS-IgA and CAS-IgG was 85.7%, for PPL-IgA was 71.4% and PPL-IgG 57.1%.(ABSTRACT TRUNCATED AT 250 WORDS)
