Immunoglobulin levels in sera and cyst fluid of human hydatidosis

Serum and cyst fluid concentrations of IgG, IgM and IgA were measured in 24 patients with hydatid disease. Serum IgG, IgM and IgA were significantly [p < 0.05] increased in patients before surgery when compared to normal controls. IgG and IgA showed a tendency to a non-significant [p > 0.05] decline to a normal control levels after a week of surgical operation. While IgM remained nearly constant after surgical removal of the cyst, IgG and IgA could cross the cyst wall into the cavity fluid while IgM could not do so
