Pharmacogenomics of suicidal events.

ABSTRACT: Pharmacogenomic studies of antidepressant treatment-emergent suicidal events in depressed patients report associations with polymorphisms in genes involved in transcription (CREB1), neuroprotection (BDNF and NTRK2), glutamatergic and noradrenergic neurotransmission (GRIA3, GRIK2 and ADRA2A), the stress and inflammatory responses (FKBP5 and IL28RA), and the synthesis of glycoproteins (PAPLN). Nearly all of the reported events in these studies were modest one-time increases in suicidal ideation. In 3231 unique subjects across six studies, 424 (13.1%) patients showed increases in suicidal ideation, eight (0.25%) attempted suicide and four (0.12%) completed suicide. Systems related to most of these genes have also been implicated in studies of suicidal behavior irrespective of treatment. Future pharmacogenomic studies should target events that are clinically significant, related clinical phenotypes of response and medication side effects, and biological pathways that are involved in these outcomes in order to improve treatment approaches.

Project description:Background:Suicidal ideations, suicide attempts, and fatal suicides are rare adverse drug reactions to antidepressant drugs, but they essentially are clinically relevant. Drawing on a larger dataset of the European drug surveillance program, the present naturalistic study updates a previous contribution (Stübner et al., 2010). Methods:First an analysis of the comprehensive data collected in 81 psychiatric hospitals from 1993 to 2014 by the European drug surveillance program Arzneimittelsicherheit in der Psychiatrie was made. All documented single cases of suicidal ideations or behavior judged as adverse drug reactions to antidepressant drugs were carefully assessed as to their clinical features and drug prescriptions. Results:Among 219,635 adult hospitalized patients taking antidepressant drugs under surveillance, 83 cases of suicidal adverse drug reactions occurred (0.04%): 44 cases of suicidal ideation, 34 attempted suicides, and 5 committed suicides were documented. Restlessness was present in 42 patients, ego-dystonic intrusive suicidal thoughts or urges in 39 patients, impulsiveness in 22 patients, and psychosis in 7 patients. Almost all adverse drug reactions occurred shortly after beginning antidepressant drug medication or increasing the dosage. Selective serotonin reuptake inhibitors caused a higher incidence of suicidal ideation and suicidal behavior as adverse drug reactions than noradrenergic and specific serotonergic antidepressants or tricyclic antidepressants, as did monotherapy consisting of one antidepressant drug, compared to combination treatments. Conclusions:The study supports the view that antidepressant drug-triggered suicidal ideation and suicidal behavior (primarily with selective serotonin reuptake inhibitors) are rare. Special clinical features (restlessness, ego-dystonic thoughts or urges, impulsiveness) may be considered as possible warning signs. A combination therapy might be preferable to antidepressant drug monotherapy when beginning treatment.
