RESUMO

OBJECTIVE: Mounting evidence suggests that antipsychotics may have immunomodulatory effects, but their impact on disseminated infections remains unknown. This study thus sought to estimate the effect of antipsychotic treatment on the occurrence of bloodstream infection during long-term follow-up in adult patients with chronic obstructive pulmonary disease. METHODS: This retrospective cohort study, with new user and active comparator design, included adult patients seen from January 2008 to June 2018 in a tertiary teaching hospital in Buenos Aires, Argentina. New users of antipsychotic drugs were compared to new users of any benzodiazepine. The primary outcome of interest was incident bloodstream infection at 1 year of follow-up. Propensity score methods and a Cox proportional hazards model were used to adjust for baseline confounding. RESULTS: A total of 923 patients were included in the present analysis. Mean (SD) age was 75.0 (9.8) years, and 51.9% of patients were female. The cumulative incidence of bloodstream infections at 1 year was 6.0% and 2.3% in the antipsychotic and benzodiazepine groups, respectively. Antipsychotic use was associated with a higher risk of bloodstream infections during the first year of follow-up (hazard ratio [HR] = 2.41; 95% CI, 1.13 to 5.14) compared to benzodiazepine use. Antipsychotics with high dopamine receptor affinity presented greater risk than less selective agents (HR = 5.20; 95% CI, 1.53 to 17.67). CONCLUSIONS: Antipsychotic use is associated with bloodstream infections during the first year of follow-up in adult patients with chronic obstructive pulmonary disease. Further studies are warranted to confirm our findings and evaluate this effect in a broader population of patients.

RESUMO

OBJECTIVE: In this study, we aimed to evaluate the role of cognitive performance and measures of clinical course-including both syndromal and subsyndromal symptomatology-as determinants of the functional outcome of patients with Bipolar Disorder (BD) during a mean follow-up period of more than 4 years. METHODS: Seventy patients with euthymic BD completed a neurocognitive battery at study entry. Clinical course was assessed prospectively for a period longer than 48 months by two measures: time spent ill (documented using a modified life charting technique) and density of affective episodes (defined as the number of depressive and hypo/manic episodes per year of follow-up). Psychosocial functioning was assessed during euthymia using the Functioning Assessment Short Test (FAST) total score at the end of follow-up period. RESULTS: Baseline deficits in phonological fluency, a measure of executive functions (ß = -2.49; 95% CI = -3.98, -0.99), and density of hypo/manic episodes during follow-up (ß = 6.54; 95% CI = 0.43, 12.65) were independently associated with FAST total score at the end of study. CONCLUSIONS: Although interrelated, manic morbidity and executive function impairments independently contribute to long-term psychosocial dysfunction in BD and could be potential targets of intervention.

RESUMO

BACKGROUND: Venous thromboembolism (VTE) represents a major cause of morbidity and mortality worldwide. Antipsychotic treatment is associated with an increased risk of thromboembolic disease, an effect that seems to be constant across the spectrum of distinct agents. This study sought to delineate the effect of new antipsychotic use on the risk of recurrent thromboembolic events after a first episode of either deep venous thrombosis or pulmonary embolism. METHODS: This cohort study, conducted between January 2010 and June 2017, was based on a prospectively collected database of adult patients with VTE. The main exposure was the new onset of antipsychotic treatment after having a first episode of venous thromboembolic disease. The primary outcome was defined as recurrent VTE, either deep venous thrombosis or pulmonary embolism, during long-term follow-up. The composite of all-cause mortality and recurrent VTE served as the secondary outcome. An inverse probability weighted multivariable Cox proportional hazards model was fitted to adjust for measured confounding and competing risks. RESULTS: One thousand one hundred three patients were included in the present analysis, of whom 136 were identified as new users of antipsychotic agents. A total of 67% of patients were currently treated with full-dose anticoagulation at baseline. No association was found between the new use of antipsychotic agents and recurrent VTE during follow-up (adjusted hazard ratio (HR) = 1.08; 95% CI, 0.38-3.08). However, the use of these agents was associated with a 63% increased risk of recurrent VTE or all-cause mortality (adjusted HR = 1.63; 95% CI, 1.26-2.10). CONCLUSIONS: The use of antipsychotic agents among patients with a first episode of VTE and full-dose anticoagulation was not associated with an increased risk of recurrent thromboembolic events. However, antipsychotic treatment was associated with a higher risk of both VTE and all-cause mortality. Further studies are warranted to confirm these findings.

RESUMO

The aim of this study was to explore outcome to antidepressants profile in melancholic unipolar depression. We conducted a systematic review of electronic databases and meta-analysis of randomized and nonrandomized trials comparing: 1) outcome to antidepressants and placebo between melancholic and non-melancholic depression; 2) outcome to different antidepressant classes in melancholic depression. Two outcomes were considered: clinical remission and response. Significant lower odds of remission to antidepressants in melancholic than in non-melancholic depressions were found. Although no significant differences were observed in the response to antidepressants between both subtypes of depression, those with melancholic features had lower odds of response to placebo. Finally, treatment of melancholic depression with serotonin reuptake inhibitors was associated with lower odds of remission compared with tricyclic antidepressants, and similar outcome compared with venlafaxine. Melancholia seems to show a differential pattern of outcome to antidepressants, which could be clinically valuable for a better implementation of personalized medicine of depression. Due to several limitations, further research is needed to support these preliminary findings.

RESUMO

We aimed to compare the mortality risk between patients with affective disorders and dementia under treatment with antipsychotics. To do this, a matched-cohort study based on an electronic database of a tertiary teaching hospital in Argentina was performed. Antipsychotic exposure was defined as any antipsychotic drug initiated by the patient. Primary outcome was defined as all-cause mortality during the 5-year follow-up period. To estimate the association between baseline diagnosis (affective disorders vs. dementia) and all-cause mortality, we used a multivariate generalized linear model with robust standard errors. Of 1008 eligible patients, 114 age-matched pairs were included in the present study. The primary event occurred in 23 patients (20%) and 17 patients (15%) in the dementia and affective disorder group respectively. In the adjusted model, the risk of all cause mortality for the affective disorders group was 0.92 times the risk for the dementia group (95%CI, 0.54-1.59, p = 0.77). In conclusion, older patients with affective disorders starting antipsychotic treatment presented with a similar risk of all-cause mortality during the 5-year follow-up when compared to older patients with dementia who were also initiating either typical or atypical antipsychotic medications. Closer medical attention to older patients with mental conditions under antipsychotic treatment remains warranted.

RESUMO

OBJECTIVE: Chronic treatment with antipsychotics may result in both metabolic side effects and cardiovascular disease. Our aim was to evaluate the effect of antipsychotic medications categorized by their metabolic side effect profiles as low, intermediate, or high risk on major cardiovascular events. METHODS: A retrospective cohort study was conducted in adult outpatients aged 30 years or older initiating antipsychotic treatment from 2002 to 2007. Antipsychotic medications were divided into 3 groups (low-, intermediate-, and high-risk) according to the severity of their side-effect profiles in developing metabolic abnormalities associated with cardiovascular disease. The primary outcome measure was the time to the composite of acute myocardial infarction, acute coronary syndrome, ischemic stroke, peripheral artery disease, or a new revascularization procedure. Inverse probability weighting of a marginal structural Cox model was used to adjust for confounding. RESULTS: A total of 1,008 patients were included (mean age = 72.4 years, median follow-up = 36.5 months), and 19.6% of patients experienced the primary outcome. The adjusted hazard ratios of a major cardiovascular event for patients in the high- or intermediate-risk medication groups compared to the low-risk group were 2.82 (95% CI, 1.57-5.05) and 2.57 (95% CI, 1.43-4.63), respectively. CONCLUSIONS: Older adult patients under antipsychotic regimens with high or intermediate risk of metabolic side effects may face a higher incidence of major cardiovascular events than those under a low-risk regimen during long-term follow-up.

RESUMO

Abstract Background In recent years, growing interest in the neuropsychology of bipolar disorder has emerged, giving rise to the accumulation of a robust body of evidence on this topic and to several related questions. Objective To provide a state-of-the-art overview of the neuropsychological profile of bipolar disorder. Method A thorough literature search was performed. Published research evidence was summarized and organized along three key pathways: findings from cross-sectional studies of cognition in bipolar patients, cognitive heterogeneity among affected subjects, and trajectory of neuropsychological deficits. Results At least two thirds of bipolar patients display neuropsychological deficits, even in euthymia. Although bipolar disorder was found to be associated with an increased risk of dementia, data from elderly subjects and longitudinal research do not support a worsening of cognitive performance over time. Discussion Cognitive dysfunctions are part of the clinical conceptualization of bipolar illness. However, they may not be present in all affected subjects and their course appears to be stable in most cases. Available evidence may be highlighting the fact that bipolar disorder is characterized by remarkable heterogeneity regarding cognitive outcomes. Different variables may be related to such heterogeneity and should be the focus of therapeutic approaches and further research.

RESUMO

BACKGROUND: There is an increasing use of ayahuasca for recreational purposes. Furthermore, there is a growing evidence for the antidepressant properties of its components. However, there are no reports on the effects of this substance in the psychiatric setting. Harmaline, one of the main components of ayahuasca, is a selective and reversible MAO-A inhibitor and a serotonin reuptake inhibitor. CASE REPORT: We present the case of a man with bipolar disorder who had a manic episode after an ayahuasca consumption ritual. This patient had had at least one hypomanic episode in the past and is currently depressed. We discuss the diagnostic repercussion of this manic episode. CONCLUSION: There is lack of specificity in the diagnosis of substance-induced mental disorder. The knowledge of the pharmacodynamic properties of ayahuasca consumption allows a more physiopathological approach to the diagnosis of the patient.
