Imunodiagnóstico da esquistossomose mansônica com baixa carga parasitária

Abstract: A esquistossom ose é endêmica em países tropicais e os dados fornecidos pela Organização Mundial de Saúde2 mostram que em localidades onde os program as de controle epidemiológico tiveram sucesso, a prevalência bem como a in te n s id a d e da in fe c ç ã o d im in u íra m consideravelmente, a par das formas graves da doença. Além disso, infecções leves são também encontradas nas áreas onde o vetor é Biomphalaria tenagophila, assim como, em pacientes após a quim ioterapia10.Em áreas de esq u isto sso m o se de… Show more

“…Under certain conditions, some serologic tests can better estimate the real prevalence of this parasitosis than the classical stool exams (Noya et al 1999). Techniques for detection of circulating antigens have not attained yet an acceptable degree of sensitivity for the diagnosis of individuals with low parasitic loads (El-Morshedy et al 1996), but methodologies that detect specific antibodies have shown sensitivity indices close to 100% (Lima et al 1996). The indirect immunofluorescence tests on worm paraffin (IgM-IFT) or frozen sections (IgG-IFT) have presented satisfactory degrees of sensitivity and specificity for diagnosis of schistosomiasis (Kanamura et al 1979, Deelder & Kornelis 1981, Silva et al 1992.…”

“…Previous studies have demonstrated the high sensitivity level of IFT-IgM in diagnosing acute as well as chronic schistosomiasis, and its specificity in relation to clinically healthy individuals as well as to those with different parasitic infections (Kanamura et al 1991, 1998a, Lima et al 1996.…”
