Introduction:

study of the relationship between intestinal parasites and atopic diseases, such as asthma or rhinoconjunctivitis, has produced contradictory results. The objective of this study was to evaluate the relationship between intestinal parasitosis and the prevalence of atopic diseases.

Material and method:

we conducted an observational, cross-sectional field study in children aged more than 2 years whose parents completed the questionnaires for evaluation of the presence of atopic diseases. We performed serial stool sample examinations and skin allergy tests in every child in the sample. The statistical analysis was carried out using the χ test with calculation of odd ratios and 95% confidence intervals. We defined statistical significance as p <0.05.

Results:

we evaluated 185 children aged 6.82±2.69 years, 52% male, 94% in the socioeconomic status category III/IV. The prevalence of atopic disease of any kind was 41%, 43% had positive results of skin allergy testing and parasites of any type were detected in 47%. We found a significant association between the results of the ISAAC questionnaire and the results of the skin prick test (p = 0.000). We did not find a significant association between the results of the skin prick test and the detection of intestinal parasitic infection (p = 1.29), or between the results of the ISAAC questionnaire and parasitic infection (p = 0.447).

Conclusion:

the findings of our study suggest that the presence of allergic conditions is not associated with the diagnosis of parasitic infection.
