Sažetak
Background: Symptomatic remission is an achievable goal in the treatment of schizophrenia. The type of antipsychotic medication and particular genetic variants of the dopaminergic system might be associated with remission. Potential pharmacogenetic markers of the treatment response to antipsychotic medication are missing. This study assessed the possible association between dopamine receptor type 2 (DRD2 rs1800497) and dopamine transporter (DAT1 rs28363170) gene variants with symptomatic remission in schizophrenia. Subjects and methods: Olanzapine (5-20 mg/d) monotherapy was administered for 6 months to 150 male Caucasian subjects with schizophrenia. Remission was evaluated according to "Remission in Schizophrenia Working Group" criteria. Genotyping was performed by PCR- RFLP. Results: Symptomatic remission was found in 31% of patients. DRD2 rs1800497 and DAT1 rs28363170 gene variants were not significantly associated with symptomatic remission. The limitations are a relatively small sample size of patients with schizophrenia (N=150), especially of group with symptomatic remission (N=45). However, the study had moderate but adequate sample sizes for most of the comparisons. Only two dopaminergic polymorphisms were analyzed, and plasma concentration of olanzapine was not determined. Conclusion: These results revealed a lack of association between DRD2 rs1800497 and DAT1 rs28363170 genetic variants and symptomatic remission in male patients treated with olanzapine, suggesting that these genetic variants could not be used to predict symptomatic remission to olanzapine monotherapy. Negative results should be further confirmed or rejected in the larger samples, including haplotype analyses, to detect clinically useful and easy obtainable pharmacogenetic markers that might predict therapeutic response or remission in schizophrenia.
