Application of pharmacogenomics in treatment-resistant schizophrenia
Objective To explore the differences in efficacy and safety of drug selection based on pharmacogenomics and evidence-based medicine for treatment-resistant schizophrenia(TRS).Methods A total of 100 patients with TRS in our hospital from January 2023 to October 2023 were divided into observation group(gene-oriented antipsychotic drug selection group,22 males and 28 females)and control group(evidence-based medicine oriented antipsychotic drug selection group,23 males and 27 females).Oral mucosal epithelial cells of the observation group were noninvasive collected with a sampling brush and antipsychotic drug gene detection was performed.Antipsychotic drugs with normal metabolism,good response and little toxic side effects were selected according to the test results,and the drugs of the control group were selected by the designated physician on the basis of the Chinese Guidelines for the Prevention and Treatment of Schizophrenia,2015 revision.Antipsychotic efficacy was evaluated before treatment and 4 weeks,8 weeks after treatment with positive and negative syndrome scale(PANSS).Treatment emergent symptom scale(TESS)was used to assess adverse reactions at the 4th and 8th weekend after treatment.Results After 8 weeks of treatment,the incidence of adverse reactions in central nervous system,autonomic nervous system,endocrine system,circulatory system and digestive system in the control group was higher than that in the observation group.The difference was remarkable.The scores of positive symptoms,negative symptoms and general psychopathological symptoms between the observation group and the control group at baseline were basically the same(P>0.05).After 4 weeks of treatment,the scores of positive symptoms,negative symptoms and general psychopathological symptoms in the observation group were lower than those in the control group.The difference was remarkable.After 8 weeks of treatment,the scores of positive symptoms,negative symptoms and general psychopathological symptoms in the observation group were lower than those in the control group.The difference was remarkable.At the end of the 8th week after treatment,the effective rate of the observation group was higher than that of the control group,the difference was remarkable(44%vs.24%,P=0.035).Two-factor repeated measurement analysis of variance was used,indicating that PANSS scores of the two groups changed with time at baseline,4 weeks and 8 weeks after treatment,and the difference was remarkable(F-time=697.139,P<0.05);The difference of PANSS among groups was remarkable(F-groups=5.398,P<0.05);PANSS score was different with different treatment methods,and the difference was remarkable(F-interaction=3.008,P<0.05).Conclusion Gene-directed antipsychotic selection maybe is superior to evidence-based antipsychotic selection in improving effective rate and reducing adverse drug reactions.
