title: Increased serum soluble interleukin-2 receptors in Caucasian and Korean schizophrenic patients.
abstract: Recent studies have identified immunologic abnormalities in some schizophrenic subjects. This experiment replicates previous findings that serum soluble interleukin-2 receptors (SIL-2Rs) are elevated in schizophrenic patients, and is the first study to describe this phenomenon in non-Caucasian patients. Despite differences between Korean and Caucasian schizophrenic patients in absolute serum SIL-2R levels, both groups were significantly elevated when compared with their respective ethnic control groups (477 +/- 171 U/ml versus 354 +/- 172 U/ml and 763 +/- 347 U/ml versus 567 +/- 231 U/ml, respectively). Neither age, gender, medication status, nor duration of illness correlated with SIL-2R levels. These findings are further evidence that immune activation is present, regardless of ethnic origin, in some schizophrenic patients.
