We investigated serum total immunoglobulin E (IgE), IgG, and IgG1 levels in patients with and without echinococcosis-induced anaphylactic shock. This was a case-control study of 11 patients with echinococcosis-induced anaphylactic shock and 22 echinococcosis patients with cyst rupture but without anaphylactic shock. Blood was collected before surgery (T0), at the time of cyst rupture (T1), and shock (Tx), 1 h (T2), 1 day (T3), and 1 week (T4) after cyst rupture. Serum IgE, IgG, and IgG1 were determined by enzyme-linked immunosorbent assay. Serum IgE, IgG, and IgG1 levels were significantly higher in patients who developed anaphylactic shock at all time points. Increased pre-surgical IgG and IgG1 levels were identified to be a significant risk factors for developing anaphylactic shock. The results showed that a serum IgG concentration of 312.25 μg/mL could be used as a cut-off point to predict whether an echinococcosis patient would develop anaphylactic shock.
