<i>Toxocara</i> Infection Seroprevalence and Its Relationship with Atopic Features in a General Adult Population

Abstract: Background: The relationship of helminth infection with atopy is controversial. Toxocariasis is the most common helminth infection in industrialized countries. The study aimed to investigate the association between Toxocara exposure and atopic features. Methods: The study is based on a cross-sectional survey of 463 subjects, randomly selected (stratified by decades of age) from a general adult population. Toxocara exposure was defined by the presence of serum Toxocara antibodies. Main outcome measures included… Show more

“…Male gender, for example, was suggested to be associated with both increased [27][28][29][30] and decreased 31 risk of infection, with some large studies showing no association between gender and risk. [32][33][34] Young age, 35 low socioeconomic status, 36 low parental education, 34,37 and poor sanitation 6 are additional factors contributing to Toxocara exposure in some communities. Dog ownership has been identified as a risk factor in several 11,27,35,[37][38][39] although not all 40 studies of urban and rural populations.…”

“…[32][33][34] Young age, 35 low socioeconomic status, 36 low parental education, 34,37 and poor sanitation 6 are additional factors contributing to Toxocara exposure in some communities. Dog ownership has been identified as a risk factor in several 11,27,35,[37][38][39] although not all 40 studies of urban and rural populations. None of these known risk factors, except for young age, was significantly associated with Toxocara exposure in our population (P values between 0.338 and 0.921 in multivariate models).…”

“…O fato de possuir cão na casa foi um fator de risco para sorologia positiva em vários estudos 17,19,20,23,24,30,31,[34][35][36] . Alguns autores não encontraram associação entre os donos de cães 17 e a frequência de infecção por Toxocara, o que poderia ser explicado pelas medidas de higiene adequadas adotadas pelos adultos.…”
