- Background: The genetic variations in norepinephrine transporter (NET) and serotonin transporter (SERT) genes have been associated with personality traits, several psychiatric disorders and the efficacy of antidepressant treatment. Aims: We investigated the separate effects and possible interactions between NET T-182C (rs2242446) and SERT 5-HTTLPR (rs4795541) polymorphisms on selective serotonin reuptake inhibitors (SSRI) treatment response and temperamental traits assessed by the Temperament and Character Inventory (TCI) in a clinical sample of subjects with major depressive disorder (MDD). Methods: Our sample of 97 patients with major depression completed the 107-item TCI temperament questionnaire (version IX) at the initial assessment of the study and after 6 weeks of follow-up. All subjects received selective SSRI medications. Temperament dimension scores at baseline (1) and endpoint (2) during antidepressant treatment were analyzed between NET and SERT genotypes. Results: SS-genotype of 5-HTTLPR was associated with higher baseline Persistence scores than SL- or LL-genotype. A corresponding but weaker association was found at endpoint. No differences were found between 5-HTTLPR genotypes and other temperament dimensions and 5-HTTLPR genotypes had no effect on treatment response. Conclusions: Our results suggest that the SS-genotype of 5-HTTLPR is associated with Persistence scores in patients with MDD. Higher Persistence could be viewed as a negative trait when recovering from stress and its association with short and "weaker" S-allele may be related to less efficient serotonin neurotransmission, possibly resulting in less effective coping strategies on a behavioral level.

- Serotonin transporter (5-HTTLPR) and norepinephrine transporter (NET182C) polymorphisms are associated with susceptibility and treatment response in major depressive disorder (MDD). Thus, we examined association between these polymorphisms and susceptibility to treatment resistant depression, and treatment response in severe MDD patients treated with electroconvulsive therapy (ECT).In total, 119 Finnish patients with treatment resistant depression and 395 healthy volunteer blood donors were genotyped. Depression severity was assessed using the Montgomery-Asberg Depression Scale (MADRS), with MADRS score change during ECT the treatment response indicator.Underrepresentation of the 5-HTTLPR 1/1 genotype in the NET TT subgroup was observed in patients compared with controls. There were no genotype or allele frequency differences between patients and control groups separately. Patients with combined 5-HTTLPR 1/1 and NET TT genotypes also had poorer treatment responses than other patients. No differences in ECT response were observed when the polymorphisms were examined separately.Our results suggest that a NET 182C and 5-HTTLPR polymorphism interaction is associated with susceptibility to treatment resistant depression and ECT treatment response in antidepressant resistant depression patients.

Manifesto for an international digital mental health network

- Current mental health services across the world remain expert-centric and are based on traditional workflows, mostly using impractical and ineffective electronic record systems or even paper-based documentation. The international network for digital mental health (IDMHN) is comprised of top-level clinicians, regulatory and ICT experts, genetic scientists, and support organizations. The IDMHN has been formed to enable the implementation of digital innovations in clinical practice, hereby facilitating the transformation of current mental health services to be more personalized and more responsive to patients and healthcare needs. This consensus statement summarizes the consortium’s vision and strategy for further development of digital mental Health.
