Antidepressant use in suicides: a case-control study from the Friuli Venezia Giulia Region, Italy, 2005-2014. Eur J Clin Pharmacol 2017; 73:883-890. [PMID: 28342066 PMCID: PMC5486927 DOI: 10.1007/s00228-017-2236-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2016] [Accepted: 03/08/2017] [Indexed: 10/27/2022]
Abstract
PURPOSE To compare the use of antidepressant (AD) classes and compounds in individuals who committed suicide and in controls from the general population and to assess to what extent adherence and current use of different AD classes can affect the risk of committing suicide. METHODS Individual data on suicide, diagnoses and AD use in Friuli Venezia Giulia from 2005 to 2014 were obtained from the Regional Social and Health Information System. All suicides that had at least one prescription of AD in the 730 days before death (N = 876) were included as cases. Each case was matched with regard to age and sex with five controls from the general population. The association between suicide and AD use was assessed using conditional logistic regression analysis. RESULTS Almost 70% of all suicides occurring in the10-year period had been prescribed AD. Selective serotonin reuptake inhibitors (SSRIs) accounted for more than the 90% of the prescriptions, with paroxetine the most prescribed AD. All AD compounds and classes were not associated with a higher suicide risk, with the exception of SSRI (OR = 1.6). A decreasing trend in suicide risk was observed when adherent subjects or current AD users were compared to the others. CONCLUSIONS AD treatment is an important factor for preventing suicide, since the use of AD at adequate dosage and for a proper duration was associated with a lower suicide risk. The proper use of AD should be ascertained by physicians, particularly in a primary care context.

Abstract
BACKGROUND A few studies have demonstrated an inverse relationship between the general population and suicide rates and antidepressant prescribing rates. Correlations between general population suicide rates and prescribing rates of other psychotropic drugs have also been observed. There have not been any studies during the last decade. METHODS The relationship between adult suicide rates and prescription rates of psychotropic drugs by the broad British National Formulary (BNF) categories, for individual psychotropic drug groups within the BNF categories (e.g. selective serotonin reuptake inhibitors) and for individual psychotropic drugs was examined over a 12-year period (1995-2006) was examined using Spearman's rank correlation. All data were ascertained from the archives of the Office for National Statistics. RESULTS There was an absence of significant correlations between adult suicides rates and rates of prescriptions of psychotropic drugs in the broad BNF categories, individual psychotropic drug groups and individual psychotropic drugs. DISCUSSION The findings may be due to methodological errors. Should the findings be accurate, then the following approaches require consideration to reduce suicide rates further: (i) development of strategies to ensure continued prescription of psychotropic drugs at the current level; (ii) development of strategies to improve non-pharmacological measures, including improved mental health services provision for adults, improved assessment of suicide risk, increased availability of psychosocial interventions and restricting the availability of methods of suicide; and (iii) development of strategies to implement improvement in distal risk (e.g. societal socio-economic status) and protective (e.g. societal educational attainment) factors for suicide at a societal level.

Abstract
Salbutamol-induced cardiac complications are well-established. Herein, we describe a case of a 24-year female who was admitted to the emergency department because of a suicide attempt with salbutamol (76 mg). Salbutamol abuse induced the development of supraventricular tachycardia and ventricular fibrillation. Regular sinus rhythm was restored with defibrillation. The hypokalemic patient who stayed in the intensive care unit was discharged after 48 hours of hospitalization.

Abstract
BACKGROUND Several studies have reported an inverse correlation between general population and elderly suicide rates and antidepressant prescribing rates. Correlations between general population and elderly suicide rates and prescribing rates of other psychotropic drugs have also been reported. All studies of elderly suicide rates have used data over a decade old. METHODS The relationship between elderly suicide rates and prescription rates of psychotropic drugs by the broad British National Formulary (BNF) categories, for individual psychotropic drug groups within the BNF categories (e.g. SSRIs), and for individual psychotropic drugs was examined over a 12-year period (1995-2006) using Spearman's rank correlation. All data were ascertained from the archives of the National Statistics Office. RESULTS There was an absence of significant correlations between elderly suicides rates and rates of prescriptions of psychotropic drugs in the broad BNF categories, individual psychotropic drug groups and individual psychotropic drugs.

Risk factors of suicide in inpatients and recently discharged patients with affective disorders. A case-control study. Eur Psychiatry 2009; 24:317-21. [PMID: 19410433 DOI: 10.1016/j.eurpsy.2008.03.011] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2006] [Revised: 03/28/2008] [Accepted: 03/28/2008] [Indexed: 11/21/2022] Open
Abstract
OBJECTIVE Patients with affective disorders are at high risk of suicide, especially during inpatient treatment and during the first year after discharge. METHODS A blinded case-control design was used. The study included a total national sample of patients with affective disorder admitted during the period from January 1, 1994 to December 31, 1995, who died because of suicide, either during admission or shortly after discharge. RESULTS A history of suicide attempt was a significant risk factor (IRR 4.9; 95% CI 2.1-11.6). Loss of job during the year prior to the index admission was associated with an increase in suicide risk (IRR: 2.9; 95% CI 1.2-7.5). Clinical improvement during the index admission (IRR: 0.3; 95% CI 0.1-0.7), and treatment with antidepressant drugs at the censoring date (IRR: 0.3; 95% CI 0.1-0.7) were associated with a decrease in suicide risk. CONCLUSION Improved treatment may be a key factor in suicide prevention in patients during, and shortly after hospitalisation with affective disorders. Also, there is a need to be especially aware of suicide risk in patients with little or no improvement at discharge.

Abstract
Completed suicide and suicide attempts are major issues in the management of bipolar disorders. There is evidence that suicide rates among these patients are more than 20-fold higher than the general population and, furthermore, suicidal behavior is much more lethal in bipolar disorder than in the general population. Patients with mood disorders may sometimes exhibit highly perturbed mixed states, which usually increase the risk of suicide. Such states are particularly frequent in bipolar II patients, especially if patients are treated with antidepressant monotherapy (unprotected by mood stabilizers), when depression switches into mania (or vice versa), or when depression lifts and functioning approaches normality. Researchers worldwide agree that treatment involving lithium is the best way to protect patients from suicide risk. Psychosocial activities, including psychoeducation, can protect bipolar patients either directly or, more probably, indirectly by increasing adherence to treatment and helping in daily difficulties that otherwise may lead to demoralization or hopelessness. An extensive understanding of the psychosocial circumstances and the psychopathology of bipolar patients (including temperament) may help clinicians describe the clinical picture accurately and prevent suicidal behavior in these patients.

Abstract
A number of reports have linked consumption of selective serotonin reuptake inhibitors (SSRIs) with suicide by violent methods. We aimed to determine whether suicides with postmortem evidence of SSRI consumption are more likely to have used violent methods compared with suicides with no detectable antidepressants. Blood samples from all suicides in Sweden during 1992-2004 were examined. Suicides were classified into those who died by violence and nonviolent (self-poisoning) methods using information from police records and autopsy. In addition, we investigated proportions of violent suicide in individuals who died with detectable levels of tricyclic and other antidepressants. The sample consisted of 14,691 suicides. Of the 1958 suicides with detectable levels of SSRIs, 1247 were by violent means (63.7%) compared with 7835 of 11,045 suicides (70.9%) in antidepressant-free group (chi2(1) = 7.6; P < 0.01). [corrected] When subdivided by gender and age-bands, we found specific groups with significantly lower proportions of violent suicides compared with the antidepressants-free group, including men aged 15-24 years.

Abstract
OBJECTIVE During the past 30 years, various cardiovascular drugs have been implicated as causes of depression or suicide. Although the evidence for causal relationships has generally been conflicting, both beta-blockers and angiotensin-converting-enzyme inhibitors (ACE-inhibitors) have been related to depression. Lipid-lowering therapies and calcium-channel blockers have also been linked to an increased risk of suicide. In this study, we investigated the possible association between the use of cardiovascular drugs and suicide using population-based register data. METHODS We performed a nested case-control study in the county of Funen, Denmark, that consisted of 743 cases of completed suicide identified in a Death Registry for the period 1991-1998 and 14,860 age- and sex-matched controls. Information on previous drug use was retrieved from prescription data and the association between suicide and use of cardiovascular drugs was analysed by conditional logistic regression. Previous exposures to other drugs were used as proxies for potential confounding co-morbidities, including the use of psychotropic drugs to indicate psychiatric illness. RESULTS The risk of suicide was not associated with current exposure to lipid-lowering drugs [odds ratio (OR): 1.21; 95% confidence interval (95% CI): 0.45-3.28), calcium-channel blockers (OR: 0.96; 95% CI: 0.63-1.48), beta-blockers (OR: 0.76; 95% CI: 0.47-1.25) or ACE-inhibitors (OR: 1.11; 95% CI: 0.68-1.83). Suicide risk was associated with current angiotensin-receptor antagonist use (OR: 3.52; 95% CI: 1.33-9.30) based on five of the cases exposed. CONCLUSION With the exception of the imprecise risk associated with current use of angiotensin-receptor antagonists, the results from our study do not support the hypothesis that other cardiovascular drugs are associated with an increased the risk of suicide.

Abstract
Antidepressant use in Denmark, as in many developed countries, has substantially increased during recent years, coinciding with a decreasing suicide rate. In a nationwide observational cohort study with linkage of registers of all prescribed antidepressants and recorded suicides in Denmark from 1995 to 2000, we investigated the relation between continued treatment with antidepressants and suicide in a population of all patients discharged from hospital psychiatry with a diagnosis of depressive disorder. Patients discharged from hospital psychiatry with a diagnosis of depressive disorder had a highly increased rate of suicide. Those who continued treatment with antidepressants had a decreased rate of suicide compared with those who purchased antidepressants once (rate ratio: 0.31, 95% confidence interval: 0.26-0.36). Further, the rate of suicide decreased consistently with the number of prescriptions. On individualized data from a cohort of patients with a known history of depressive disorder, continued antidepressant treatment was associated with reduced risk of suicide.

Abstract
As in many developed countries, the use of antidepressants in Denmark has been substantially increasing during recent years, coinciding with a decreasing suicide rate. We aimed to investigate the relationship between treatment with antidepressants and suicide on individualized data from a nationwide study comprising an observational cohort study with linkage of registers of all prescribed antidepressants and recorded suicides in Denmark during the period 1995-99. A total of 438 625 patients who purchased at least one prescription of antidepressants and 1073 862 individuals from the general population were included in the study. Patients who continued treatment with selective serotonin reuptake inhibitors (SSRIs) (i.e. who purchased SSRIs twice or more) had a decreased rate of suicide compared with patients who purchased SSRIs once only [rate ratio (RR)=0.63; 95% confidence interval (CI)=0.56-0.71]. Furthermore, the rate of suicide decreased consistently with the number of prescriptions. Similarly, among patients treated with newer antidepressants other than SSRIs, the rate of suicide was decreased compared with the rate for patients who purchased other newer antidepressants once only (RR=0.70; 95% CI=0.52-0.94). Continued antidepressant treatment with SSRIs or other newer antidepressants is found to be associated with a reduced risk of suicide.

Abstract
PURPOSE To investigate whether antidepressants are over-used, under-used, or misused, by determining to what extent the depressed individuals in a defined population are treated with antidepressant medication and, from the other end, to what extent prescribed antidepressants are aimed for the treatment of depression. SUBJECTS AND METHOD From an individual based prescription database in the County of Jämtland, 2048 individuals representative for the general population were selected. The presence of current depression in these individuals was screened by a mailed self-screening questionnaire. Individuals with depression according to the questionnaire were interviewed by a psychiatrist using a structured interview (SCAN) to confirm the diagnosis. Their use of antidepressants was obtained from the prescription database. RESULTS Sixty-two (4.5%) out of 1375 were diagnosed with depression and 17 (27%) of these were taking an antidepressant. In addition 44 individuals, currently not depressed, were taking antidepressants. Twenty-five of these were interviewed per telephone and it was found that the indications for 18 of them were continuation treatment of depression, and for seven of them pain, sleep disturbance or anxiety. CONCLUSION Antidepressants appear to be under-used in the population. Only one in four of the depressed individuals was treated with antidepressant medication. Those who had antidepressant medication without being currently depressed had, with few exceptions, either continuation treatment for depression in remission or treatment on other approved indications.

Abstract
Bipolar disorders are prevalent, often severe, and disabling illnesses with elevated lethality largely due to suicide. Suicide rates average approximately 1% annually, or perhaps 60 times higher than the international population rate of 0.015% annually. Suicidal acts typically occur early in bipolar disorders and in association with severe depressive or mixed states. The high lethality of suicidal acts in bipolar disorders is suggested by a much lower ratio of attempts:suicide (approximately 3:1) than in the general population (approximately 30:1). Risk factors can help to identify patients at increased suicidal risk, but ongoing clinical assessment is essential to limit risk. Empirical short-term interventions to manage acute suicidal risk include close clinical supervision, rapid hospitalization, and electroconvulsive therapy. Remarkably, however, evidence of the long-term effectiveness of most treatments against suicidal behavior is rare. A notable exception is lithium prophylaxis, which is associated with consistent evidence of major (approximately 80%), sustained relative reductions of risk of suicides and attempts, and lower lethality (increased attempts:suicide ratio). Such benefits are unproved for other treatments commonly used to treat bipolar disorder patients, including anticonvulsants, antipsychotics, antidepressants, and psychosocial interventions. Applying available knowledge systematically, with close and sustained clinical supervision, can enhance management of suicidal risk in bipolar disorders patients.

Abstract
Patients' accounts complement psychiatric assessment of deliberate self-harm (DSH). In this study we examined psychiatric disorders, and sociocultural and cross-cultural features of DSH. SCID diagnostic interviews and a locally adapted EMIC interview were used to study 196 patients after DSH at a general hospital in Mumbai, India. Major depression was the most common diagnosis (38.8%), followed by substance use disorders (16.8%), but 44.4% of patients did not meet criteria for an enduring Axis-I disorder (no diagnosis, V-code, or adjustment disorder). Psychache arising from patient-identified sociocultural contexts and stressors complements, but does not necessarily fulfill, criteria for explanatory psychiatric disorders.

Abstract
We determined the rates of suicide in two consecutive time intervals of low and high selective serotonin reuptake inhibitor (SSRI) prescribing for men and women with mood disorders, who were at relatively high risk of suicide, in a discharged hospitalized sample. High quality Swedish national registers were cross-linked to estimate rates of suicide. The results were stratified by three age-bands, and rates of comorbid substance misuse were explored. These were compared with general population suicide rates. There were 1606 suicides in discharged patients with mood disorders. Suicide rates decreased for all women during 1989-94 and 1995-2000 [odds ratio (OR) = 0.74, 95% confidence interval (CI) = 0.64-0.85] and a trend was found towards lower rates in men (OR = 0.89, 95% CI = 0.78-1.02). Approximately 90% of suicides occurred in those aged over 40 years; thus, the inpatient sample lacked the power to discriminate clear effects in the younger age groups. There was no increase or decrease in the rates of substance use disorders in patients who committed suicide. There were 20 851 suicides in the general population during 1989-2000. Suicide rates were lower at all ages for men and women in the general population in the interval of high SSRI prescribing. We conclude that there is no evidence from this study of an increase in suicide rates following the introduction of SSRIs in the general population or in a high-risk inpatient sample.

A record evaluation of 98 suicide victims with a primary severe depression had been performed. These had been admitted to the Department of Psychiatry, Lund University Hospital between 1956 and 1969 and followed up to 1998. Psychomotor retardation was related to completed suicide after ECT. The estimated frequency of lethal intoxication with antidepressants was low: 3% of the suicides.

Abstract
OBJECTIVE Numerous authors have reported serious shortcomings in the treatment of suicidal patients. This study examined the treatment suicide attempters admitted to a psychiatric hospital in Switzerland had received prior to the suicide attempt. METHOD Thirty-one patients were admitted to this hospital within a year, representing 36 suicide attempts, which corresponds to 6.5% of the annual admission number. Three of these patients were admitted twice, and one patient was admitted three times. Information on previous treatment was collected in personal interviews and included medication, and its dosage, at 1 month and 2 weeks prior to the suicide attempt, and whether the patient had received psychotherapy. In addition, details of the psychosocial event and the means of the suicide attempt were recorded. RESULTS Twenty-one patients had been prescribed psychotropic drugs in 24 events, but only in 17 events concerning 15 patients, antidepressants were prescribed prior to hospitalisation. Antipsychotics and benzodiazepines were prescribed in 6 and 21 events, respectively (including 8 events with hypnotics). None of the patients was treated with lithium. In 19 events, 16 patients had received psychotherapy prior to admission. In 32 events, psychotropic drugs were used for the suicide attempt. CONCLUSION The findings confirm the undertreatment of patients attempting suicide reported by other authors. In spite of the majority of patients being under psychiatric care, no adequate pharmacotherapy had been prescribed particularly for depressed patients.

Abstract
Regulatory agencies in the United Kingdom and United States have been critically examining the possible link between suicidality and antidepressant use in children and adults, which has resulted in an FDA directive to the manufacturers of all antidepressant medications to add a 'black box' warning that describes the increased risk of suicidal behaviour in children and adolescents who take antidepressants. A crucial issue in this debate, as we discuss here, is the assessment of the capacity of antidepressants to increase suicidality over and above what is caused by the underlying disorder, major depression, which is itself the principal cause of suicide.

Abstract
In recent years, there has been much debate regarding the real cost effectiveness of new antidepressants. This review is an attempt to identify key contentious methodological issues that can impact the reliability, validity and quality of the research on this subject. There are inherent complexities between inputs and outcomes related to depression, and the choice of pharmacoeconomic methodology requires a crucial balance between the study design and its ability to capture relevant information. Knowledge of the real efficiency of antidepressants should always be ascertained with reference to the real-world setting. Studies that show a corresponding balance between internal and external validity, coupled with sound methodology and standardised reporting, have the potential to translate pharmacoeconomics research into real-world, time-relevant decision-making.

Abstract
OBJECTIVE To compare the rates of suicidal behaviour during vs. after discontinuation of treatment with antidepressants, and to determine the comparative rates of suicidal behaviour for patients maintained on tricyclic (TCA) vs. selective serotonin reuptake inhibitor (SSRI) antidepressants. METHOD Charts were reviewed for 521 patients with major depressive disorder and/or dysthymic disorder. Periods of active treatment or discontinuation with SSRIs or TCAs were determined. Rates of completed suicide, suicide attempts, and hospitalization for suicidality were analyzed. RESULTS There was greater than a five-fold increase in risk for suicidal behaviour after discontinuation of antidepressant treatment (P < 0.0001). The rates of suicidal behavior during treatment with SSRIs or TCAs were similar. CONCLUSION Suicidal behaviour in unipolar depressed patients treated with antidepressants increases substantially after medication discontinuation. This effect occurred in both patients who were maintained on SSRIs and TCAs. The findings support a possible protective effect on suicidal behaviour for both SSRIs and TCAs.

Abstract
The authors consider the extent to which psychotropic medications demonstrate benefits in the prevention of suicidal behavior in psychiatric patients. Results of a MedLine search are critically reviewed for lithium, divalproex and other anticonvulsants, conventional and atypical antipsychotics, and antidepressants. The existing literature is almost entirely limited to noncontrolled, often retrospective studies that do not control for potential biases in treatment selection, the use of multiple medications, the impact of medication nonadherence, and nonrandomized treatment discontinuations. Nevertheless, an extensive literature has arisen regarding observed reductions in suicidal behavior with lithium for mood disorders and, to a lesser extent, with clozapine for schizophrenia. A substantially smaller literature suggests more negative than positive data with divalproex or carbamazepine in bipolar disorder, while minimal information exists regarding suicidality with atypical antipsychotics other than clozapine. Studies of antidepressants have mostly been short-term and have focused more on whether they induce (rather than ameliorate) suicidal thoughts or behaviors. The sum of existing studies is generally inconclusive about whether antidepressants appreciably reduce risk for suicide completions. Relatively little is known about pharmacotherapy effects on suicidal ideation as distinct from behaviors. Possible mechanistic considerations for understanding antisuicide properties include a therapeutic impact on depression, impulsivity, or aggression, potentially mediated through serotonergic or other neuromodulatory systems. Recommendations are provided to guide future research as well as clinical practice.

Abstract
OBJECTIVE To examine the indications for prescribing antidepressants and the clinical outcome when they are prescribed for the treatment of depression, and compare tricyclic antidepressants (TCAs) and selective serotonin re-uptake inhibitors (SSRIs) in these respects. METHOD A naturalistic study of a prospective prescription monitoring database and medical records. RESULTS Depression was the indication for 23% of the tricyclic treatments and for 82% of the SSRI treatments. A successful treatment of the depression was found in 20% of the TCA cases and 41% of the SSRI cases (NS). CONCLUSION This study provides evidence that the main use of SSRIs in 1995 is the treatment of depression. The study implies that SSRIs have a more favourable outcome in "real life" than TCAs.

Abstract
Bipolar (manic-depressive) disorder is a common and severe illness. It is also potentially fatal as a result of accidents and increased mortality associated with comorbid substance use and medical illnesses, but its highest lethality results from suicide. Suicide rates, averaging 0.4% per year in men and women diagnosed with bipolar disorder, are >20-fold higher than in the general population. Suicidal acts often occur early in the illness course and in association with severe depressive and dysphoric-agitated mixed phases of illness, especially following repeated, severe depressions. Systematic consideration of risk and protective factors enhances assessment of potentially suicidal patients. Short-term interventions employed empirically to manage acute suicidality include close clinical supervision, rapid hospitalisation and use of electroconvulsive treatment. Several plausible therapeutic interventions have limited evidence of long-term effectiveness against mortality risks associated with any psychiatric disorder, including antidepressant, antimanic, antipsychotic and electroconvulsive, as well as psychosocial, treatments. However, in bipolar disorder and other major affective disorders, lithium maintenance treatment is a notable exception, with strong and consistent evidence that it reduces suicidal risk. The growing range of drugs being introduced to treat acute and long-term phases of bipolar disorder, including antiepileptic drugs, atypical antipsychotics and relatively safe, modern antidepressants, require research assessment for their ability to limit premature mortality from suicide and other causes. For now, however, more can be done to improve treatment in major affective illnesses by application of current knowledge in a systematic fashion, with close and sustained clinical follow-up of patients at risk, hopefully with a resulting reduction of mortality rates.
