Treatment with some types of antidepressants has been associated with sudden cardiac death. It is unknown whether the increased risk is due to a class effect or related to specific antidepressants within drug classes. All patients in Denmark with an out-of-hospital cardiac arrest (OHCA) were identified (2001-2007). Association between treatment with specific antidepressants and OHCA was examined by conditional logistic regression in case-time-control models. We identified 19,110 patients with an OHCA; 2,913 (15.2%) were receiving antidepressant treatment at the time of OHCA, with citalopram being the most frequently used type of antidepressant (50.8%). Tricyclic antidepressants (TCAs; odds ratio (OR) = 1.69, confidence interval (CI): 1.14-2.50) and selective serotonin reuptake inhibitors (SSRIs; OR = 1.21, CI: 1.00-1.47) were both associated with comparable increases in risk of OHCA, whereas no association was found for serotonin-norepinephrine reuptake inhibitors/noradrenergic and specific serotonergic antidepressants (SNRIs/NaSSAs; OR = 1.06, CI: 0.81-1.39). The increased risks were primarily driven by: citalopram (OR = 1.29, CI: 1.02-1.63) and nortriptyline (OR = 5.14, CI: 2.17-12.2). An association between cardiac arrest and antidepressant use could be documented in both the SSRI and TCA classes of drugs.

Acta Psychiatr Scand 1999: 100: 119–125. © Munksgaard 1999. Objective: The aim of this study was to examine the temporal stability of neurological abnormalities in first‐episode schizophrenic patients, and to clarify the relationships between such abnormalities and psychopathology. Method: A total of 18 schizophrenic patients, 11 non‐schizophrenic patients and 10 healthy volunteers were examined neurologically at first admission and 5 years later. Results: A significant increase in the number of neurological abnormalities was seen in schizophrenic patients with genetic predisposition and in patients with a non‐remitting course of disease. Birth complications had an impact on the occurrence of neurological abnormalities at first admission. Conclusion: The association between a deteriorating course of disease and neurological impairment supports the theory that any possible impairment of the brain in schizophrenia is aggravated during the first 5 years of disease.

A subcommittee under the Danish Psychiatric Association and the Child and Adolescent Psychiatric Association in Denmark have recently developed national guidelines for the psychopharmacological treatment with lithium and antiepileptic drugs, and the present translation aims at contributing to the international discussion on the development of proper guidelines for the treatment of bipolar disorder. Among the antiepileptic drugs, the report deals with valproate, carbamazepine and lamotrigine and to a lesser extent with oxcarbazepine, gabapentin and topiramate. The various drugs will be reviewed, outlining the scientific evidence for mood‐stabilizing properties and discussing major side effects, the most important interactions with other drugs and practical use. Special considerations during pregnancy and lactation, during treatment of children and adolescents and during treatment of the elderly will also be presented. Antidepressants and antipsychotics are beyond the scope of the report, but due to the mood‐stabilizing properties of at least some of the atypical antipsychotics, these agents will be brought into some focus in connection with the overall treatment guidelines for the different phases of bipolar disorder given at the end of this report.

This article is a clinical guide which discusses the “state-of-the-art” usage of the classic monoamine oxidase inhibitor (MAOI) antidepressants (phenelzine, tranylcypromine, and isocarboxazid) in modern psychiatric practice. The guide is for all clinicians, including those who may not be experienced MAOI prescribers. It discusses indications, drug-drug interactions, side-effect management, and the safety of various augmentation strategies. There is a clear and broad consensus (more than 70 international expert endorsers), based on 6 decades of experience, for the recommendations herein exposited. They are based on empirical evidence and expert opinion—this guide is presented as a new specialist-consensus standard. The guide provides practical clinical advice, and is the basis for the rational use of these drugs, particularly because it improves and updates knowledge, and corrects the various misconceptions that have hitherto been prominent in the literature, partly due to insufficient knowledge of pharmacology. The guide suggests that MAOIs should always be considered in cases of treatment-resistant depression (including those melancholic in nature), and prior to electroconvulsive therapy—while taking into account of patient preference. In selected cases, they may be considered earlier in the treatment algorithm than has previously been customary, and should not be regarded as drugs of last resort; they may prove decisively effective when many other treatments have failed. The guide clarifies key points on the concomitant use of incorrectly proscribed drugs such as methylphenidate and some tricyclic antidepressants. It also illustrates the straightforward “bridging” methods that may be used to transition simply and safely from other antidepressants to MAOIs.
