Correlation between SERT polymorphisms and Venlafaxine response in major depression patients

Major depression (MD) has a complex multifactorial aetiology with genetic and environmental factors contributing to this disorder. As with all antidepressant treatments, there is variability in drug response because of heredity, and this leads us to focus on the genetic polymorphism of the drug's metabolising transporter genes. The serotonin transporter (5-HTT) gene is a particularly important candidate for genetic involvement in MD disorders owing to its key role in the regulation of serotonergic transmission and is therefore considered an interesting candidate in the mechanism of antidepressant drugs. Here, we studied the associations between genetic polymorphisms in two regions of the 5-HTT gene (5-HTTLPR and VNTR) to understand venlafaxine response. Venlafaxine was found to be effective in MD patients based on their HAM-D and CGI scores (p<0.05). Although the results did not yield a significant difference between the frequencies of the SS, LS,LL, 9/9, 10/10, 12/12 and 10/12 genotypes and venlafaxine response, venlafaxine dose was increased in patients with Stin2.12 and S alleles. These alleles might have a predisposition to mood disorders. Further studies with more patients are required to confirm this clinical association.

Objective-Citalopram (CITA) is a widely used and well-tolerated selective serotonin reuptake inhibitor. The aim of the study was to evaluate the possible influences of serum concentrations of CITA and its major metabolite n-desmethylcitalopram (NDCITA) on the efficacy and tolerability of CITA in patients with major depressive disorder. Methods-The study included 46 outpatients with major depressive disorder who received CITA. The efficacy and tolerability were assessed for 6 weeks. Serum CITA and NDCITA levels were measured at the 4th week. Results-The HDRS17 total scores of the patients with high NDCITA and CITA & NDCITA concentrations showed a more significant reduction compared to the patients with expected and low serum NDCITA and CITA & NDCITA concentrations. However, we did not observe a correlation between the serum concentrations and the side effects of CITA, NDCITA, and CITA & NDCITA. Conclusion-Our results suggested the potential contribution of NDCITA to the antidepressant effect of CITA. Further studies involving larger clinical samples are required to confirm the impact of serum NDCITA concentrations on the efficacy of CITA.
