Abstract

We examined the catechol-O-methyl transferase (COMT) Val108/158Met genotype in 160 type 1 bipolar patients. We also analyzed the plasma concentrations of homovanillic acid (HVA), 3-methoxy-4-hydroxyphenylethylenglycol (MHPG) and 3,4-dihydroxyphenylacetic acid in 60 of those patients who had been without mood stabilizers or neuroleptic treatment for at least 8 days. Results: Patients with congruent psychotic symptoms presented a higher plasma concentration of HVA than mood incongruent psychotic patients. The Val/Val genotype was associated with higher plasma concentrations of HVA and MHPG. We detected a larger proportion of patients with psychotic symptoms in the Val/Val genotype group, although this did not reach statistical significance. It was found that the distribution of the COMT genotype was not influenced by the congruent/incongruent nature of the psychotic symptoms. Limitations: The proportion of patients without psychotic symptoms in our sample was low. This fact limits the value of some comparisons. Conclusions: Congruent and incongruent psychotic patients can be distinguished in terms of the concentration of plasma HVA. Based on the presence or absence of mood incongruent symptoms, the Val108/158Met polymorphism of the COMT gene alone does not appear to be a crucial determinant in the division of psychotic bipolar patients. Nevertheless, COMT polymorphisms may influence some of the characteristics of the patients by their effect on monoamine metabolism.
