[The clinico-immunological characteristics of hymenolepiasis].

Clinical manifestations were observed only 16 out of 61 patients aged 15-32 years who had hymenolepiasis. Despite their degree, there was impaired dexylose absorption, lower serum lysozyme activity and higher serum complement activity, depressed immunological reactivity parameters (the count of T- and B-lymphocytes, their functional activity), decreased IgA titer and increased IgE titer in the sera in all the patients observed. Six months after the effective dehelminthization, varying immunodepression still remained in all the convalescents. There types of restoration of immunological reactivity were identified: torpid, reactive and highly reactive. The torpid type was significantly more frequently observed in patients with subclinical (asymptomatic) hymenolepiasis course than in patients with its clinical manifestation.
