Some immunological studies on amoebiasis

ABSTRACT

Studies of immunoglobulins pattern in 64 patients with different clinical symptoms of amoebiasis revealed that IgG showed no rise in patients with acute amoebic dysentery and asymptomatic cyst passers, while it was significantly increased in patients with active hepatic amoebiasis. IgM, IgA and IgE were significantly increased in both acute amoebic dysentery and active hepatic amoebiasis, but no significant changes in asymptomatic cyst passers. ELISA [depended on level of IgG] was valid and reliable in diagnosis of active hepatic amoebiasis [100%], IHAT [depended on level of IgM] gave 72.7% and 46.9% in patients with acute amoebic dysentery and active hepatic amoebiasis, respectively
