title: Homocysteine levels in adolescent schizophrenia patients.
abstract: Homocysteine is a sulfur containing amino acid that has been widely investigated for its putative role in cardiovascular and neuropsychiatric disorders. It has been suggested that homocysteine has implications especially in young, male schizophrenia patients. In this prospective case-control study, we compared plasma homocysteine levels in a group of adolescent schizophrenia inpatients (aged 14-21 years; n=23) to normal healthy controls (n=51). Mean plasma homocysteine levels were significantly higher in the patient group than in the control group (15.40+/-2.00 and 9.78+/-0.33 micromol/L, respectively, p<0.032). The difference was almost entirely attributable to the male schizophrenia subgroup (18.18+/-5.65 in male patients vs. 10.31+/-5.33 micromol/L in female patients). The group x sex interaction was statistically significant (p=0.0035). These data indicate that a subgroup of male adolescent schizophrenia patients has high homocysteine blood levels. The role of homocysteine in the pathophysiology of adolescent-onset schizophrenia merits further investigation.
