چکیده
A s ín d r o m e q u e a c o m p a n h a a hiperimunoglobulinemia E (hiper-IgE), como descrita originalmente por Buckley e cols2 em 1972, consistia de susceptibilidade aumentada a infecções, particularmente por estafilococos, e n ív e is s é r ic o s de IgE e x tre m a m e n te elevados (> 2000ng/ml). Demostrou-se a seguir que estes indivíduos também apresentavam deficiência na quimiotaxia neutrofílica. A partir daí, descreveram-se síndromes similares que associavam hiper-IgE e manifestações atópicas. O sobrenadante de cultura de células T, retiradas de pacientes com atopia grave e de pacientes com doenças parasitárias, induz a produção de IgE in vitro. A IgE de indivíduos com verminoses pode causar danos graves ao hospedeiro ao estimular mastócitos a secretarem mediadores tóxicos. A ruptura de cistos hidáticos pode provocar choque anafilático. Ataques asm atiform es ocorrem em in fecçõ e s por Toxocara canis e na eosinofilia pulmonar tropical da filariose. Note-se que, fatores solúveis derivados de células T de indivíduos nãoatópicos suprime os sintomas e sinais mediados por IgE.
