The adenoids and tonsils are thought to be essential parts of the system protecting organism against pathogens invading the upper respiratory tracts. Human adenoids and tonsils are known to be immunologically reactive lymphoid organs, which manifest specific antibodies and B and T cells activity in response to variety of antigens carrying out the functions of humoral and cellular immunity. The purpose of the study was to observe the changes in systemic immunity in children with hypertrophy of adenoids and tonsils treated in Department of Laryngology, Children's Hospital in Warsaw in period 1994-1999. The study comprised 80 patients (33 girls and 47 boys, aged from 3 to 14 years, mean age 6.8 years) with diagnosed hypertrophy of adenoids and tonsils. The diagnosis of hypertrophy of adenoids and tonsils was based on characteristic history and laryngological examination. All patients were scheduled for adenotonsillotomy. The control group comprised 40 people (14 girls and 26 boys, aged from 3 to 15 years, mean age 7.6 years) without history of the recurrent upper tract infections. In all patients we carried out following examinations: serum levels of immunoglobulins A, G, M (humoral immunity); percentage of T lymphocytes (CD3); percentage of T helper (CD4) and T cytotoxic (CD8) lymphocytes (cellular immunity) and delayed cutaneous hypersensitivity-Multitest CMI (cell mediated immunity). Our study demonstrate that in children with hypertrophy of adenoids and tonsils exist changes in the immunological parameters. The observed changes appear not only locally but also generally. In the early period after adenotonsillotomy there was statistically significant decrease of the values of humoral and cellular immunity parameters. However, 6 months after operation we observed normalization of examined immunological parameters. We think that the examinations of parameters of immunological system (humoral and cellular) are necessary before planned adenotonsillotomy.
