摘　　要：AIM:Intestinal parasitic diseases are commonly accompanied with diarrhoeal symptoms and allergic reactions.Eosinophilia occurs as a result of IL-5 synthesized from Th2 cells during allergic reactions.IL-5 acts as a factor activating eosinophils. The aim of this study was to compare the IL-5 cytokine measurements in serum samples and cell cultures.And also to compare eosinophilia observed in helminth infections and protozoon infections accompanied with allergy. METHODS:Twenty-three patients who presented with diarrhoeal symptoms and allergic complaints were tested positive for intestinal parasites,as well as 21 controls with allergic complaints who did not have any intestinal parasites were included in this study.IL-5 production in in vitro cell cultures prepared by using phytohemaglutinin (PHA) to stimulate peripheral blood mononuclear cells (PBMC) obtained from the blood samples taken from these patients were compared with the IL-5 level in serum.Furthermore, the IL-5 production in protozoon and helminth infections was also compared.Absolute eosinophil values in 1 mm^3 of blood were calculated by means of peripheral smear in both groups within the scope of the study. RESULTS:Parasites such as helminth detected in 15 (65.2%) and protozoon in 8 (34.8%) of the patients were included in this study.As regards the values of the sera in both patients with parasite infection and controls,the IL-5 production was found to be higher in the cell culture supernatant (P<0.001 and P<0.05).When the IL-5 level of the patients with helminth parasites was compared with that of those with protozoon,it was determined that the IL-5 level in serum was more significant in the patients with protozoon than in those with helminth (P<0.05).In the study group,the patients were found to have parasites, the percentage of eosinophil was 7.0% compared to 6.5% in the control group.Thus,there was no significant difference between the eosinophil values (P>0.05).
