title: Increased serum IgE in schizophrenic patients who responded poorly to neuroleptic treatment.
abstract: Total serum IgE and plasma Interleukin (IL)-4 have been determined in patients with schizophrenia, 26 neuroleptic-free, and 81 neuroleptic-treated, and in 46 healthy control subjects. The total serum IgE was significantly higher in the patients who responded poorly to neuroleptic treatment compared with the other four groups (F = 4.27, df = 4, 148, P < 0.003). No significant changes were found in plasma IL-4 levels between any of the five groups. It is possible that raised serum IgE levels may characterise a subgroup of schizophrenia.
