Psychiatric comorbidity in individuals with bipolar disorder: relation with clinical outcomes and functioning.

The aim was to assess the lifetime prevalence of psychiatric comorbidity (PC) in Brazilian euthymic individuals with bipolar disorder type I, and investigate its effects on clinical outcomes and functioning. A group of 179 outpatients with BD-I in the recuperation phase were assessed, of whom 75 (41.9%) had PC and 104 (58.1%) had not. Both groups were compared using sociodemographic/clinical questionnaire, Structured Clinical Interview for DSM-IV axis I and II, Sheehan Disability and Barratt Impulsiveness Scales. Patients with PC presented less religious affiliation, more history of lifetime psychotic symptoms, rapid cycling, suicide attempts, worse scores of functioning, and higher prevalence of personality disorders. Ordinal logistic regression indicated that PC was associated with increased odds of worse levels of disability. Therefore, it could be observed that patients with BD evaluated only in euthymia presented a high mental disorders comorbidity. Considering their burdensome impact, appropriate management is a challenging reality and a crucial factor in reducing morbidity and mortality associated with BD. Further longitudinal studies on their relationship may broaden interventions to reduce patient's suffering.

Social support among individuals with bipolar disorder during euthymic phase: A systematic review.

INTRODUCTION: In spite of the recent increase in scientific publications showing an expressive interest in studies about social support, there are still scarce publications regarding this thematic and bipolar disorder, mostly when evaluating the individuals in the state of euthymia. Euthymia referred a state that a bipolar patient does not have signs/symptoms of (hipo)mania or depression, thus assessing individuals in this state may reduce response bias. OBJECTIVE: The objective of this study is to identify the impact of social support on bipolar disorder in patients in the euthymic phase. METHODS: A systematic search of observational studies on PubMed/Medline, PsycINFO, EMBASE, Scopus and Web of Science databases was performed from February 2021 to August 2022. RESULTS: In total, seven studies fulfilled the eligibility criteria. According to three studies, bipolar disorder patients had lower social support than healthy controls. Contrastingly, one study showed bipolar patients did not have different social support compared to healthy controls. CONCLUSIONS: Even though few papers with low or middle risk of bias were included in this review, we found that not only does social support could act as a protective factor for bipolar patients but also that clinical manifestations of the disorder seem to affect social support. This systematic review suggests the narrowed evidence field with different measures and type of evaluation from studies on social support and bipolar disorder, which highlights the need for further investigations on this theme.

History of suicide attempts in patients with bipolar disorder type I: socio-demographic and clinical factors, quality of life and functioning.

INTRODUCTION: This study aims to evaluate sociodemographic and clinical factors, quality of life (QoL) and functioning associated with history of suicide attempts (SA) in a sample of bipolar disorder (BD) type I patients. METHODS: A total of 417 BD type I patients, with and without history of SA were recruited from two Brazilian specialized Mood Disorder Centers. They were assessed with a sociodemographic and clinical questionnaire, the Young Mania Rating Scale, the Hamilton Depression Rating Scale, the Structured Clinical Interviews for DSM-IV Axis I Disorders, the World Health Organization Quality of Life-BREF, and the Sheehan Disability Scale. RESULTS: One hundred and seventy-nine (42.9%) patients had a history of SA. There were no statistically significant sociodemographic differences between BD patients with and without a history of SA. Logistic regression found that lifetime hospitalization, comorbid anxiety disorders, depressive polarity in the first episode, current intensity of depressive symptoms, history of rapid cycling, family history of suicide and age at onset were significantly associated with SA in BD. Multiple linear regression showed that SA had no effect on QoL and functioning, which were affected mainly by comorbid anxiety disorders and current intensity of depressive symptoms, even in patients considered euthymic. CONCLUSION: Suicidal behavior in patients with BD is a complex phenomenon and reflects a more severe course of illness. Patients with history of SA may have worse QoL and functional impairment not because of its direct effect, but because of the greater association with clinical factors related to poor prognosis.

Functioning in euthymic patients with bipolar disorder: A systematic review and meta-analysis using the Functioning Assessment Short Test.

OBJECTIVES: Systematically review the prevalence of functional impairment (FI) in euthymic patients with bipolar disorder (BD), as assessed only with the Functioning Assessment Short Test (FAST), explore the prevalence of this impairment among all the domains, identify the most compromised of them and the clinical variables associated with low functioning in this population. METHODS: Meta-analyses were performed, searching for relevant papers published from 2007 to 2019 in Medline, Embase, Cochrane, PsycINFO databases and via hand-searching, without language restrictions. 1128 studies were initially identified, 13 of which were ultimately chosen based on the eligibility criteria. A two-step meta-analysis was performed using the mean difference with a 95% confidence interval for continuous variables and proportion estimation with a fixed-effects model for categorical variables. RESULTS: In the first step, all FAST domains showed worse FI in patients than in healthy controls, with significant differences between groups. In the second step, the prevalence of FI domains were as follows: global, 58.6%; occupational, 65.6%; cognitive, 49.2%; autonomy, 42.6%; interpersonal relationships, 42.1%; leisure, 29.2%; and financial issues, 28.8%. Residual depressive symptoms were the most frequently cited variable associated with FI. CONCLUSIONS: This study reinforces the relevant functional impact of BD in this population and suggests that the occupational domain may be the most impaired. Greater efforts should be directed toward targeting functioning in patient care, as it constitutes the most meaningful endpoint of response to treatment, especially with occupational and cognitive rehabilitation, thus allowing patients to overcome the course of illness and carry fulfilling lives.

Psychiatric disorders in individuals diagnosed with gender dysphoria: A systematic review.

AIM: Although there has been an increase in the social acceptance of the gender dysphoria (GD) population, these individuals still suffer a high degree of emotional stress, which highlights the importance of knowing their mental illness diagnosis. METHODS: A systematic review was conducted to identify the frequency of lifetime Axis I mental disorders in this population, using the MEDLINE/PubMed, SciELO, Cochrane, EMBASE, and PsychINFO databases and manual searching, examining articles published after 1980. The search used the key words: ('transgender' OR 'gender identity disorder' OR 'gender dysphoria' OR 'transsexualism' OR 'gender dysphoric patients' OR 'gender incongruence') AND ('mental disorder' OR 'axis I' OR 'psychiatric disorders') AND ('comorbidity' OR 'comorbid' OR 'prevalence'). RESULTS: From 233 papers found, five were included. The total sample comprised 577 individuals diagnosed with GD, of whom 307 (53.2%) had presented with at least one mental disorder in their lifetime. Among this high frequency of Axis I disorders, mood disorders were the most frequent (found in 243 individuals [42.1%]), followed by anxiety disorders (155 [26.8%]), and substance use/abuse disorders (85 [14.7%]). CONCLUSION: This study offers important data to researchers and clinicians so they can recognize and contribute to the development of public policy on the mental health of the population diagnosed with GD. The mental health of these individuals requires special attention as it contributes to their functional impairment.

Lifetime prevalence of psychiatric comorbidities in patients with bipolar disorder: A systematic review and meta-analysis.

BACKGROUND: Bipolar disorder (BD) is a severe psychiatric disease and part of its burden is related to the high rates of lifetime psychiatric comorbidity (PC), with diagnostic, therapeutic, and prognostic implications. METHODS: Registered in PROSPERO (CRD42021282356). Meta-analyses were performed, searching for relevant papers published from 1993 to 2022 in Medline/PubMed (including E-Pub Ahead of Print), Embase, Cochrane Library (Central), PsycINFO, Scopus, Web of Science and via hand-searching, without language restrictions. 12.698 studies were initially identified, 114 of which were ultimately chosen based on the eligibility criteria. We performed two meta-analyses (prevalence and risk ratio) of mental health conditions among subjects with BD and then conducted a comprehensive examination of moderator effects using multivariable meta-regression models for moderators identified as significant in the univariable analysis. FINDINGS: Overall PC prevalence of at least one disorder was 38.91 % (95 % CI 35.24-42.70) and the most frequent disorders were: anxiety (40.4 % [34.97-46.06]), SUD (30.7 % [23.73-38.73]), ADHD (18.6 % [10.66-30.33]) and Disruptive, impulse-control and conduct disorder (15 % [6.21-31.84). The moderators with higher association with individual prevalences were UN's Human Development Index (HDI), female gender, age, suicide attempt, and age at onset (AAO). INTERPRETATION: It becomes evident that the prevalence of PC among individuals with BD is notably high, surpassing rates observed in the general population. This heightened prevalence persists despite significant heterogeneity across studies. Consequently, it is imperative to redirect clinical focus towards comprehensive mental health assessments, emphasizing personalized and routine screening. Additionally, there is a pressing need for the enhancement of public policies to create a supportive environment for individuals with BD, ensuring better therapeutic conditions and sustained assistance. By addressing these aspects, we can collectively strive towards fostering improved mental health outcomes for individuals with BD.
