    The objective of this study was to investigate the relationship between the genetic polymorphism of the serotonin transporter gene-linked polymorphic region (5-HTTLPR) and the response to citalopram treatment and side effects in Turkish patients with major depressive disorder. The study involved 51 patients who received 10-40 mg/day of citalopram for 4 to 6 weeks. Clinical symptoms were evaluated by the 17-item Hamilton Depression Rating (HAMD-17) scale, Clinical Global Impression (CGI) and UKU side effect rating scale (UKU) at weeks 4 and/or 6. The 5-HTTLPRL/S polymorphism was determined by slowdown-polymerase chain reaction method. Of the fifty-one patients, 13 (26%) were the LL genotype, 21 (41%) were the LS genotype, 17 (33%) were the SS genotype. L allele seems to be associated with better response due to odds ratio for L allele versus S allele despite statistically insignificant. In terms of CGI-Severity scale, The LL genotype versus the LS genotype had a higher risk at the week 6 (P<0.05). On the other hand, apart from this comparison, there is no significant difference in CGI-Severity and Improvement and UKU scales according to the distribution of genotypes at week 4 and/or 6. However, these findings surely need further investigation and confirmation. © 2016, Turkish Pharmacists Association. All rights reserved.

    The relationship between the serotonin 2A receptor gene-1438A/G and 102T/C polymorphisms and citalopram/sertraline-induced nausea in major depressed patients
    (Wiley, 2018) Oz, Merve Demirbugen; Uckun, Zuhal; Yuce-Artun, Nazan; Baskak, Bora; Ozdemir, Hatice; Ozel, Tugba Kizil; Suzen, H. Sinan
    Objective: The aim of the present study was to determine the relationship between the polymorphisms of -1438A/G and 102T/C in the 5-HT2A receptor (HTR2A) gene and nausea/vomiting as a side effect induced by sertraline (SERT) or citalopram (CIT) in patients with major depressive disorder. Methods: A total of 128 patients were enrolled, 63 patients received CIT, whereas 65 patients were treated with SERT. Nausea/vomiting were assessed with the UKU Side-effects Rating Scale at baseline and at the end of the second and fourth weeks. Polymerase chain reaction-restriction fragment length polymorphism technique was employed to determine genetic differences. Results: We have found that, in the patients treated with CIT, there was a nominally significant difference in the genotypic distribution associated with -1438A/G polymorphism between patients with and without nausea (X-2 = 6.15, p = 0.041). Moreover, logistic regression analysis revealed a significant association between nausea/vomiting as a side effect and -1438A/G polymorphism. That is, patients with the G allele were at a higher risk for developing nausea/vomiting (p = 0.044, odds ratio = 2.213). The 102T/C polymorphism in the HTR2A gene had no significant effect on the nausea/vomiting as a side effect among participants treated with either CIT or SERT. Conclusion: The present study suggests the association of the HTR2A gene -1438A/G polymorphism with nausea/vomiting as a side effect related to CIT treatment.
