RESUMO

OBJECTIVE: The treatment of bipolar depression remains challenging due to the limited effective and safe therapeutic options available; thus, developing newer treatments that are effective and well tolerable is an urgent unmet need. The objective of the present trial was to test 150 to 300 mg/day of cannabidiol as an adjunctive treatment for bipolar depression. METHOD: A randomized, double-blind, placebo-controlled pilot study to assess the efficacy of adjunctive cannabidiol in bipolar depression was used. Efficacy parameters were changes in the Montgomery-Åsberg Depression Rating Scale (MADRS) from baseline to week 8. Secondary outcomes included response and remission rates, changes in anxiety and psychotic symptoms, and changes in functioning. Patients continued double-blind treatment until week 12 to monitor for adverse effects, laboratory analysis, and manic symptoms. Study registry: NCT03310593. RESULTS: A total of 35 participants were included. MADRS scores significantly decreased from baseline to the endpoint (placebo, -14.56; cannabidiol, -15.38), but there was no significant difference between the groups. Similarly, there were no other significant effects on the secondary outcomes. However, an exploratory analysis showed a significant effect of cannabidiol 300 mg/day in reducing MADRS scores from week 2 to week 8 (placebo, -6.64; cannabidiol, -13.72). There were no significant differences in the development of manic symptoms or any other adverse effects. CONCLUSION: Cannabidiol did not show significantly higher adverse effects than placebo. Despite the negative finding on the primary outcome, an exploratory analysis suggested that cannabidiol should be further studied in bipolar depression in higher doses of at least 300 mg/day and under research designs that could better control for high placebo response.

RESUMO

Background: Psychiatric disorders are associated with more than 90% of reported suicide attempts worldwide, but few treatments have demonstrated a direct effect in reducing suicide risk. Ketamine, originally an anesthetic, has been shown anti-suicide effects in clinical trials designed to treat depression. However, changes at the biochemical level were assessed only in protocols of ketamine with very limited sample sizes, particularly when the subcutaneous route was considered. In addition, the inflammatory changes associated with ketamine effects and their correlation with response to treatment, dose-effect, and suicide risk warrant further investigation. Therefore, we aimed to assess whether ketamine results in better control of suicidal ideation and/or behavior in patients with depressive episodes and whether ketamine affects psychopathology and inflammatory biomarkers. Materials and methods: We report here the design of a naturalistic prospective multicenter study protocol of ketamine in depressive episodes carried out at Hospital de Clínicas de Porto Alegre (HCPA) and Hospital Moinhos de Vento (HMV). The study was planned to recruit adult patients with Major depressive disorder (MDD) or Bipolar disorder (BD) types 1 or 2, who are currently in a depressive episode and show symptoms of suicidal ideation and/or behavior according to the Columbia-Suicide Severity Rating Scale (C-SSRS) and have been prescribed ketamine by their assistant psychiatrist. Patients receive ketamine subcutaneously (SC) twice a week for 1 month, but the frequency can be changed or the dose decreased according to the assistant physician's decision. After the last ketamine session, patients are followed-up via telephone once a month for up to 6 months. The data will be analyzed using repeated measures statistics to evaluate the reduction in suicide risk as a primary outcome, as per C-SSRS. Discussion: We discuss the need for studies with longer follow-ups designed to measure a direct impact on suicide risk and that additional information about the safety and tolerability of ketamine in particular subset of patients such as those with depression and ideation suicide. In line, the mechanism behind the immunomodulatory effects of ketamine is still poorly understood. Trial registration: https://clinicaltrials.gov/, identifier NCT05249309.

RESUMO

The Third Argentine Consensus on the management of bipolar disorders (TB) is an initiative of the Argentine Association of Biological Psychiatry (AAPB). As a reference document, this consensus pursues two main objectives: on the one hand, to summarize and systematize the best available evidence on the comprehensive management of this pathology; on the other, to provide a useful, up-to-date instrument for psychiatrists, multidisciplinary teams dedicated to mental health, and government agencies. During a period of approximately six months of work -that is, from May to October 2022- a committee of experts made up of 18 professionals and representatives of the three most important Psychiatry and Mental Health associations in Argentina (that is, the AAPB, the Argentine Association of Psychiatrists, AAP, and the Association of Argentine Psychiatrists, APSA) have focused on updating the information regarding TB. Finally, this document was prepared as a result of an exhaustive review of the bibliography published to date, which was strategically divided into three parts: the first deals with the generalities of TB; the second deals with the comprehensive treatment of the pathology; finally, the third analyzes TB in the context of special situations.


El Tercer Consenso Argentino sobre el manejo de los Trastornos Bipolares (TB) es una iniciativa de la Asociación Argentina de Psiquiatría Biológica (AAPB). Como documento de referencia, este consenso persigue dos objetivos principales: por un lado, resumir y sistematizar la mejor evidencia disponible sobre el manejo integral de esta patología; por el otro, proporcionar un instrumento útil y actualizado a psiquiatras, a equipos multidisciplinarios abocados a la salud mental y a organismos gubernamentales. Durante un período de aproximadamente seis meses de trabajo -desde mayo a octubre de 2022- un comité de expertos integrado por 18 profesionales y por representantes de las tres asociaciones de Psiquiatría y Salud Mental más importantes de la Argentina: la AAPB, la Asociación Argentina de Psiquiatras, (AAP) y la Asociación de Psiquiatras Argentinos (APSA), se abocaron a actualizar la información respecto de los TB. Finalmente, y como resultado de una exhaustiva revisión de la bibliográfica publicada hasta la actualidad, se confeccionó este documento que fue dividido estratégicamente en tres partes: la primera versa acerca de las generalidades del TB; la segunda aborda el  tratamiento integral de la patología; y, por último, la tercera analiza los TB en el contexto de situaciones especiales.

RESUMO

INTRODUCTION: The administration of multiple esketamine doses has shown efficacy for unipolar and bipolar treatment-resistant depression (TRD). Nevertheless, the probability of responding or not after each dose in the real-world remains unknown. This study aimed to estimate it throughout four doses of esketamine, administrated via subcutaneous (SC). MATERIAL AND METHODS: We conducted a retrospective analysis of a case series of 70 patients with TRD who received treatment from the esketamine assistance program at Federal University of Sao Paulo, between April 2017 and December 2018. The SC injections were administrated weekly at a dose of 0.5-1.0mg/kg, in conjunction with patients' psychotropic drugs. Response was defined as a decrease of at least 50% in the Montgomery-Åsberg Depression Rating Scale between baseline and 24h after dose. We used hidden Markov modeling in order to estimate de probability of response after each esketamine injection. RESULTS: The probability of a patient that was a "non-responder" to become a "responder" following a SC injection of esketamine was 17.30% and the probability that this patient remains a "non-responder" was 82.70%. The probability of a patient that was a "responder" to remain as a "responder" was 95%. CONCLUSIONS: Patients with TRD who had not responded after the first dose of esketamine, still had a chance of responding after the subsequent dose administrated via SC.

RESUMO

ABSTRACT Objective: The aim of this article is to compare differences in metacognitive beliefs between bipolar disorder type I depressed (BPD1) patients with Unipolar Depression (UPD) patients, and a control group; and to discuss the relationship between metacognitive beliefs and depression parameters. Methods: Sixty six consecutive outpatients with a diagnosis of depressed BPD1, 70 patients with UPD and 70 healthy controls were enrolled in the study. Following assessment with the Sociodemographic Data Form, Structured Clinical Interview for DSM-IV (SCID-I), Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scales (HAM-A), Young Mania Evaluation Scale, and the Metacognition Questionnaire-30 (MCQ-30). Results: UPD and BPD1 patients included in the study had higher scores in metacognitive beliefs other than positive beliefs compared with healthy controls (p<0.05), but no significant difference was found between the BPD1 and UPD groups (p>0.05). A statistically significant positive correlation was observed between the HAM-A, HAM-D scores and MCQ-30 scores in UPD group (p<0.05) but not in BPD1 group (p>0.05). Discussion: The metacogitive structures of UPD and BPD1, may be helpful in identifying and choosing the right treatment modality. We think that our results may have implications for the metacognitive approaches in the treatment of BPD1.

RESUMO

BACKGROUND: Bipolar disorder is a disabling disease characterized by the recurrence of mood episodes. Successful strategies for the acute treatment of bipolar depression are still a matter of controversy. Total sleep deprivation (TSD) has shown acute antidepressant effect; however, the prompt relapse of depressive symptoms after sleep recovery has been reported. Taking this into consideration, we aimed to address a twofold research question: what are the acute effects of adding TSD to pharmacological treatment and what are the acute and chronic effects of adding medications to TSD. METHODS: MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched for clinical trials assessing bipolar depression and TSD. Two independent reviewers selected and classified 90 abstracts. The outcomes we assessed were change in Hamilton Depression Rating Scale (HDRS) or Montgomery-Asberg Depression Rating Scale (MADRS), sustained long-term response rate, treatment-emergent mania or hypomania, and tolerability (using dropout rates as a proxy). The compared groups were: TSD alone versus TSD plus medications and medications alone versus medications plus TSD. Data was analyzed using Stata 16.0. RESULTS: Patients treated with TSD plus medications compared with medications alone showed a significant decrease in depressive symptomatology after one week (SMD -0.584 [95% CI -1.126 to -0.042], p = 0.03. Also, a significant decrease in depressive symptomatology (SMD -0.894 [95% CI -1.388 to -0.399], p < 0.001) was found in the group with TSD plus medications compared with TSD alone, at the 10th day of treatment. We meta-analyzed the long-term effect of the TSD. It showed a sustained antidepressant effect (log OR = 2.365 (95% CI 0.95 to 3.779, p < 0.001) in the group where TSD was combined with medication when compared with patients treated only with TSD. Finally, no differences in tolerability (log OR = 0.234 (95% CI -1.164 to 1.632, p = 0.74) or affective switch were found. CONCLUSION: Adding TSD to medications to bipolar depression treatment resulted in an augmentation in acute response. We also found that medications have a positive impact in acute response when added to TSD. Furthermore, this higher response rate was maintained after 3 months while keeping Lithium therapy.

RESUMO

Introduction: The use of antidepressants (AD) in the treatment of bipolar depression is one of the most controversial issues in psychopharmacology. For some, AD are useful, but, for others, they should never be used in bipolar depression. Areas covered: This review examines published clinical studies on the use of ADs in bipolar depression, addressing their clinical efficacy and the occurrence of side effects, manic switches, cycle acceleration, and suicidal behavior. Meta-analyzes and review articles on the subject are also discussed. Expert opinion: Approved therapeutic options for bipolar depression are associated with not very high response rates and a high incidence of adverse effects. Patients with bipolar depression present very heterogeneous responses to the use of ADs. Some improve significantly, while others, especially those with concomitant manic symptoms, have had previous episodes of treatment-emergent mania or are rapid cyclers, exhibit manic switches or cycle acceleration. The authors conclude that the real question is not whether ADs should or should not be used in bipolar depression, but which patients benefit from these drugs and which ones are impaired. The concept of bipolar spectrum and a dimensional approach on bipolar/unipolar distinction may be useful for understanding the heterogeneity of responses to ADs.

RESUMO

OBJECTIVE: The purpose of this study was to assess the efficacy and tolerability of tianeptine as an adjunctive maintenance treatment for bipolar depression. METHODS: This is a multicenter double-blind randomized placebo-controlled maintenance trial of adjunctive tianeptine 37.5 mg/day. Participants ( n=161) had a Montgomery-Asberg Depression Rating Scale ⩾12 at entry. After eight weeks of open-label tianeptine treatment, those who responded to tianeptine ( n=69) were randomized to adjunctive tianeptine ( n=36) or placebo ( n=33) in addition to usual treatment. Kaplan-Meier estimates and the Mantel-Cox log-rank test were used to evaluate differences in time to intervention for a mood episode between the tianeptine and placebo groups. We also assessed overall functioning, biological rhythms, quality of life, rates of manic switch and serum brain-derived neurotrophic factor levels. RESULTS: There were no differences between adjunctive tianeptine or placebo regarding time to intervention or depression scores in the 24-week double-blind controlled phase. Patients in the tianeptine group showed better performance in the letter-number sequencing subtest from the Wechsler Adult Intelligence Scale at the endpoint ( p=0.014). Tianeptine was well tolerated and not associated with higher risk for manic switch compared to placebo. CONCLUSION: Tianeptine was not more effective than placebo in the maintenance treatment of bipolar depression. There is preliminary evidence suggesting a pro-cognitive effect of tianeptine in working memory compared to placebo.

RESUMO

INTRODUCTION: Subjects with bipolar disorder suffering of a depressive episode are frequently misdiagnosed as unipolar depression, being important studies assessing the differential diagnosis between bipolar and unipolar depression. OBJECTIVE: To assess the sociodemographic and clinical features of drug-free young adults in a depressive episode of bipolar or unipolar disorder in order to identify factors that may differentiate these psychiatric conditions. METHODS: This is a cross-sectional study with 241 young adults aged between 18 and 29 years who were evaluated using the Structured Clinical Interview for DSM-IV (SCID). The sample comprised patients with BD (n = 89) and major depressive disorder (n = 152), experiencing a depressive episode and not using psychoactive drugs or illicit psychoactive substances. RESULTS: The characteristics associated with bipolar depression were being male (p < 0.001), with a family history of BD (p = 0.013), a higher frequency of childhood traumatic experiences (p = 0.001), younger age of onset of mood disorder (p = 0.004), many previous depressive episodes (p = 0.027), greater severity of depressive symptoms (p < 0.001) and day/night reversal (p = 0.013). Those with unipolar depression showed a higher frequency of biological rhythm disturbances (p < 0.001), and diurnal preference (p = 0.028). LIMITATIONS: The sample has not included subjects with severe suicide risk, a possible important marker in differentiate unipolar from bipolar depression. CONCLUSION: Some clinical aspects may contribute to an early differential diagnosis of both bipolar and unipolar depression even in the initial stages of the disease.

RESUMO

INTRODUCTION: Lamotrigine (LTG) is a well-established anticonvulsant that is also approved for the prevention of mood relapses in bipolar disorder. However, the mechanisms underlying LTG mood stabilizing effects remain unclear. Areas covered: Herein, the pre-clinical evidence concerning LTG's' mode of action in depression and mania is reviewed. Bottlenecks and future perspectives for this expanding and promising field are also discussed. Pre-clinical studies have indicated that neurotransmitter systems, especially serotoninergic, noradrenergic and glutamatergic, as well as non-neurotransmitter pathways such as inflammation and oxidative processes might play a role in LTG's antidepressant effects. The mechanisms underlying LTG's anti-manic properties remain to be fully explored, but the available pre-clinical evidence points out to the role of glutamatergic neurotransmission, possibly through AMPA-receptors. Expert opinion: A major limitation of current pre-clinical investigations is that there are no experimental models that recapitulate the complexity of bipolar disorder. Significant methodological differences concerning time and dose of LTG treatment, administration route, animal strains, and behavioral paradigms also hamper the reproducibility of the findings, leading to contradictory conclusions. Moreover, the role of other mechanisms (e.g. inositol phosphate and GSK3ß pathways) implicated in the mode of action of different mood-stabilizers must also be consolidated with LTG.

RESUMO

Abstract Introduction Affective state may influence insight, especially regarding mania. Nevertheless, studies have so far suggested that depression seems not to significantly impair insight. To the best of our knowledge, this study pioneers the evaluation of how insight variations in bipolar depression correlate with clinical variables. Method A group of 165 bipolar patients, 52 of whom had depressive episodes according to DSM-5 criteria, were followed during a year. All patients underwent clinical assessment, and insight was evaluated through the Insight Scale for Affective Disorders (ISAD). Repeated-measures ANOVA was calculated comparing scores on the four ISAD factors (insight into symptoms, the condition itself, self-esteem and social relationships) in order to investigate differences in insight according to different objects. Correlational analysis explored which clinical symptoms were linked to reduced insight. Results Worse total insight correlated with suicide attempt/ideation and fewer subsyndromal manic symptoms such as mood elevation, increased energy and sexual interest. Worse self-esteem insight was associated with not only suicide ideation/attempt but also with activity reduction and psychomotor retardation. Worse symptom insight also correlated with psychomotor retardation. Better insight into having an affective disorder was associated with more intense hypochondria symptoms. Finally, worse insight into having an illness was associated with psychotic episodes. Conclusion Our study found that symptoms other than psychosis - suicide ideation, psychomotor retardation and reduction of activity and work - correlate with insight impairment in bipolar depression.


Resumo Introdução O estado afetivo pode influenciar o insight , especialmente a mania. No entanto, até o momento os estudos mostram que a depressão parece não prejudicar significativamente o insight . De acordo com o conhecimento dos autores, este estudo é pioneiro em avaliar como as alterações de insight na depressão bipolar se correlacionam com variáveis clínicas. Método Um grupo de 165 pacientes bipolares, com 52 pacientes apresentando episódios depressivos de acordo com os critérios do DSM-5, foi acompanhado por um ano. Os pacientes foram submetidos a avaliação clínica, e o insight foi avaliado utilizandose a Insight Scale for Affective Disorders (ISAD). Diferenças no insight de acordo com o objeto foram investigadas utilizandose ANOVA de medidas repetidas, comparando os escores dos quatro fatores da ISAD ( insight sobre sintomas, sobre sua condição, autoestima e relações sociais). Análises de correlação exploraram quais sintomas clínicos estiveram associados a redução de insight . Resultados Pior insight total correlacionou-se com ideação/tentativa de suicídio e com sintomas subsindrômicos de mania (elevação do humor, energia aumentada e interesse sexual). Pior insight sobre autoestima associou-se não somente a ideação/tentativa de suicídio, mas também a redução de atividade e alentecimento psicomotor. Pior insight sobre sintomas também mostrou correlação com alentecimento psicomotor. Melhor insight sobre ter uma doença afetiva associou-se a sintomas hipocondríacos mais intensos. Finalmente, pior insight sobre a condição esteve associado a sintomas psicóticos. Conclusão O estudo mostrou que, além da psicose, outros sintomas parecem se correlacionar com prejuízo de insight na depressão bipolar, como ideação suicida, redução de atividade e alentecimento psicomotor.

RESUMO

INTRODUCTION: Bipolar disorder is a chronic disabling condition characterized by alternating manic and depressive episodes. Bipolar disorder has been associated with functional impairment, poor quality of life, morbidity and mortality. Despite its significant clinical, social and economic burden, treatment options for bipolar disorder are still limited. Several clinical trials have shown efficacy of the atypical antipsychotic quetiapine (QTP) in the treatment of this condition. However, the mechanisms underlying the antidepressant and anti-manic effects of QTP remain poorly understood. Areas covered: The article provides the emerging evidence from pre-clinical studies regarding the antidepressant and anti-manic mechanisms of action of QTP. In combination with its primary active metabolite norquetiapine, QTP modulates several neurotransmitter systems, including serotonin, dopamine, noradrenaline and histamine. QTP also seems to influence mediators of the immune system. Expert opinion: Pre-clinical studies have provided valuable information on the potential antidepressant mechanisms of action of QTP, but pre-clinical studies on QTP's anti-manic effects are still scarce. A major problem refers to the lack of valid experimental models for bipolar disorder. Additionally, immune and genetic based studies are largely descriptive. The role of the QTP metabolite norquetiapine in modulating non-neurotransmitter systems also needs to be further addressed.

RESUMO

OBJECTIVE: To systematically examine the effects of dopaminergic agents (modafinil, armodafinil, pramipexole, methylphenidate, and amphetamines) on bipolar depression outcomes. METHODS: Meta-analysis of randomized controlled trials was performed to assess the efficacy and safety of treatment with dopaminergic agents in bipolar depression. In a secondary analysis, findings from both randomized controlled trials and high-quality observational studies were pooled by means of meta-analytic procedures to explore dopaminergic treatment-related new mania. RESULTS: Nine studies (1716 patients) were included in our meta-analysis of randomized controlled trials. Treatment with dopaminergic agents for bipolar depression was associated with an increase in both response (1671 individuals, RR 1.25, 95% CI 1.05 to 1.50) and remission rates (1671 individuals, RR 1.40, 95% CI 1.14, 1.71). There was no evidence of an increased risk of mood switch associated with this treatment (1646 individuals, RR 0.96, 95% CI 0.49, 1.89). Our secondary analysis (1231 individuals) yielded a cumulative incidence of mood switch of 3% (95% CI 1.0, 5.0) during a mean follow-up period of 7.5 months. CONCLUSIONS: Preliminary findings suggest that dopaminergic agents may represent a useful alternative for the treatment of bipolar depression, with no evidence for a related increase in the risk of mood destabilization during short-term follow-up.

RESUMO

Suicide is a relatively common outcome along the course of bipolar disorder. Studies have shown a positive correlation between ideation or attempts of suicide and higher insight in schizophrenic patients. Nevertheless there are still few studies that evaluate the relationship between suicide and insight in mood disorders. Evaluate the relationship between insight and suicidal ideation or behavior in bipolar depression. A group of 165 bipolar patients were followed up along 1 year. Each patient's mood was assessed in every consultation according to DSM-IV-TR criteria. Suicidal ideation and behavior were prospectively assessed through item 3 of HAM-D whenever a major depressive episode was diagnosed. Insight was evaluated through the Insight Scale for Affective Disorders. A history of suicidal attempts was associated with worse insight in 60 patients with one episode of bipolar depression. The difference remained even when the supposed effect of depression over insight was controlled. No correlation between current suicidal ideation and insight level was found though. Our results suggest that a history of suicide attempts may correlate with higher impairment of insight in bipolar depression. No relationship was found between current suicidal ideation and insight.

RESUMO

Introdução: O transtorno bipolar é uma doença crônica e grave, caracterizada por episódios recorrentes, representando um enorme fardo aos indivíduos acometidos e seus familiares. Objetivos: Conhecer o perfil clínico de pacientes com transtorno bipolar atendidos em um ambulatório especializado do Sul Catarinense.

RESUMO

INTRODUCTION: It is important to make distinction between bipolar and unipolar depression because treatment and prognosis are different. Since the diagnosis of the two conditions is purely clinical, find symptomatic differences is useful. OBJECTIVES: Find differences in subjective experience (first person) between unipolar and bipolar depression. METHODS: Phenomenological-oriented qualitative exploratory study of 12 patients (7 with bipolar depression and 5 with unipolar depression, 3 men and 9 women). We used a semi-structured interview based on Examination of Anomalous Self-Experience (EASE). RESULTS: The predominant mood in bipolar depression is emotional dampening, in unipolar is sadness. The bodily experience in bipolar is of a heavy, tired body; an element that inserts between the desires of acting and performing actions and becomes an obstacle to the movement. In unipolar is of a body that feels more comfortable with the stillness than activity, like laziness of everyday life. Cognition and the stream of consciousness: in bipolar depression, compared with unipolar, thinking is slower, as if to overcome obstacles in their course. There are more difficult to understand what is heard or read. Future perspective: in bipolar depression, hopelessness is stronger and broader than in unipolar, as if the very possibility of hope was lost. CONCLUSIONS: Qualitative differences in predominant mood, bodily experience, cognition and future perspective were found between bipolar and unipolar depression.

RESUMO

Introducción: Es importante distinguir la depresión unipolar de la bipolar, pues hay diferencias en el tratamiento y el pronóstico. Dado que el diagnóstico de las dos condiciones es netamente clínico, encontrar diferencias sintomáticas puede ser de gran utilidad. Objetivos: Buscar diferencias en la experiencia subjetiva (de primera persona) entre depresión unipolar y bipolar. Métodos: Estudio exploratorio de tipo cualitativo, de orientación fenomenológica, con 12 pacientes (7 con depresión bipolar y 5 con depresión unipolar; 3 varones y 9 mujeres). Se utilizó una entrevista semiestructurada basada en el Examen de la Experiencia Anómala del Self (EASE). Resultados: Estado de ánimo predominante: en la depresión bipolar es el apagamiento emocional; en la unipolar, la tristeza. Experiencia del cuerpo: en la bipolar, el cuerpo se siente pesado, francamente cansado y como un obstáculo para el movimiento. En la unipolar, la experiencia del cuerpo se parece a la pereza cotidiana. Cognición y flujo de conciencia: en la depresión bipolar, en comparación con la unipolar, el pensamiento se vive lentificado, como si tuviera que vencer obstáculos en su curso; hay mayor dificultad para comprender lo que se escucha o se lee. Perspectiva del futuro: en la depresión bipolar, la desesperanza es más intensa y de mayor alcance que en la unipolar, como si se perdiera la posibilidad misma de la esperanza. Conclusiones: Se encontraron diferencias cualitativas en el estado de ánimo predominante, la experiencia corporal, la cognición y la perspectiva del futuro entre la depresión unipolar y la bipolar.
