[Correlation between immunohistochemical indices of adenoid vegetations and health of ailing children].

We studied correlations between clinical characteristics of ailing children and their immunohistochemical parameters. Clinical status was assessed by the degree of adenoid vegetations, duration of the disease, the presence of chronic tonsillitis or its combination with adenoiditis. We used the following immunohistochemical parameters: the level of CD3+ in histological slices and the presence or absence of IgA-producing cells. Correlation was found between the presence or absence of IgA-producing cells and the degree of adenoid vegetations as well as the presence only of chronic tonsillitis or chronic tonsillitis plus adenoiditis. We found also important but statistically insignificant differences: in a group of patients with the disease duration up to 2 years CD3+ cells were absent, while in children with the disease duration more than 5 years these cells were present. Thus, immunohistochemical parameters are rather informative in interpretation of a clinical picture in ailing children.
