• Cerebrospinal fluid hormones, monoaminergic metabolites, and dynorphin A (1-8 sequence) were examined in 43 children with severe, primary obsessive-compulsive disorder. Cerebrospinal fluid levels of 5-hydroxyindoleacetic acid were positively correlated with one of eight obsessivecompulsive disorder severity ratings and three of seven measures of improvement following 5 weeks of treatment with clomipramine hydrochloride. Arginine vasopressin concentration was significantly and negatively correlated with several ratings of obsessive-compulsive disorder symptom severity, while oxytocin concentration was positively correlated with depressive symptoms. The ratio of arginine vasopressin to oxytocin was also negatively correlated with obsessive-compulsive disorder and depressive symptoms. Comorbid affective disorder was associated with decreased arginine vasopressin concentrations, while concomitant anxiety disorder was associated with increased oxytocin. Dynorphin A (1-8 sequence), homovanillic acid, corticotropin, 3-methoxy-4-hydroxyphenylglycol, and corticotropin releasing hormone were not significantly related to obsessive-compulsive disorder symptoms. These results seem to indicate that arginine vasopressin may be related to obsessive-compulsive disorder symptom severity, while 5-hydroxyindoleacetic acid might be associated with drug response.
