title: Defective yeast opsonization and C2 deficiency in atopic patients.
abstract: Twenty-seven per cent of atopic patients initially presenting with infantile eczema or hay fever were defective for yeast opsonization and 18% had low levels of C2; these deficiencies were mutually exclusive, suggesting that they are primary. Both defects were associated with each of four different atopic syndromes, some of which were related to certain HLA haplotypes.
