[Clinico-immunologic examinations of foreign nationals with parasitic diseases].

Clinical and laboratory parameters were studied in a randomly selected series of East Asian population. A total of 31 subjects, whose ages ranged from 18 to 20 years and who came to Czechoslovakia for a long term study of working stay, were examined. The series represented healthy population. On examination marked infestation with intestinal helminths was established. Trichuris trichiura was found in 70.9% of probands, Ascaris lumbricoides in 43.3%, while both parasites were present in 25.8%. HBsAg positivity was recorded in 38.7% of probands and as many as 75% these had markedly increased serum transaminase values. Besides mildly increased IgG levels, immunological examination yielded significantly raised IgE levels which decreased after deparasitation. Although expected, eosinophilia failed to be present.
