STUDY OF COCKROACH HYPERSENSITIVITY IN CH ILDREN - MESOLOGIC SIGHTS

CAP-RAST() i6 was systematically performed in sera of 400 children an d adolescents admitted in an allergy unit. The frequency of this sensi tisation was 0.238 among allergic subjects. In the whole population di scriminant factors were 1) the age of the patient, 2) clinical asthma. A case-control study revealed: 1 degrees) more marked atopic criterio ns (house dust mite and/or timothy grass pollen associated sensitisati ons; increased IgE level); 2 degrees) sociologic factors: popular hous ing and immigrant families. It was already stated that these immigrant populations had enhanced pre-disposition to develop asthma. This prop ensity, renforced by unfavourable environment, indicates immigrant fam ilies as high risk population for respiratory allergy.
