عنوان انگلیسی HUMORAL AND CELLULAR IMMUNITY PARAMETERS IN CHILDREN BEFORE AND AFTER ADENOTONSILLECTOMY
چکیده انگلیسی مقاله Adenoids and tonsils are active lymphoid organs and play an important role ‎against invading antigens of upper aerodigestive tract in children. ‎The present study analyzes the changes in cellular and humoral immunity of children six ‎months after adenotonsillectomy. The study population consisted of 30 children whit chronic adenotonsillar hypertrophy and 30 age-matched healthy children. ‎In all children serum level of IgM and IgG, percentage of T lymphocytes (CD3), T ‎helper cells (CD4), T cytotoxic ‎cells (CD8) and B lymphocytes (CD20) were measured before surgery. These parameters were ‎remeasured in patients 6 months after adenotonsillectomy. ‎Before the operation, a reduction in percentage of T lymphocytes (CD3),TCD4,TC8 ‎and B CD20 was seen compared to control group. This reduction was only significant in T ‎lymphocytes (CD3).The serum IgM and IgG levels were not different in two groups. Six months after ‎operation, the percentage of lymphocytes T CD3, T CD8 and BCD20 was increased and ‎reached the control group. The IgM level was also significantly decreased in patients after ‎operation. ‎Our results indicate that cellular and humoral immunity decreases in children ‎with chronic adenotonsiller hypertrophy preoperatively and increases to healthy children ‎level, six months postoperatively. It means that chronic adenotosillar hypertrophy affect ‎some parameters of cellular and humoral immunity and adenotonsillectomy by removing ‎chronic stimulations and reverses these changes without any negative effect on immune ‎function of patients.
