Risk factors for suicidality in patients with panic disorder: A systematic review and meta-analysis

Latent Profile Analysis of Suicidal Ideation in Chinese Individuals with Bipolar Disorder

Individuals with bipolar disorder (BD) have a greater suicide risk than the general population. In this study, we employed latent profile analysis (LPA) to explore whether Chinese individuals with different phases of BD differed at the levels of suicidal ideation. We recruited 517 patients. Depressive symptoms were measured using the 24-item Hamilton Depression Rating Scale (HAMD-24), and manic symptoms were evaluated using the Young Mania Rating Scale (YMRS). The extent of suicidal thoughts was determined through the Beck Scale for Suicide Ideation (BSSI). The scores of HAMD and YMRS were used to perform LPA. LPA categorized participants into three classes: one exhibiting severe depressive and mild manic symptomatology, another showing severe depressive and severe manic symptomatology, and the third one displaying severe depressive and intermediate manic symptomatology. Suicidal ideation levels were found to be remarkably elevated across all three classes. Additionally, the three classes showed no significant differences in terms of suicidal ideation. Our research confirms the link between depressive symptoms and suicide, independent of the manic symptoms. These findings carry meaning as they provide insight into the suicide risk profiles within different phases of BD.

Investigating Relations Between the Symptoms of Panic, Agoraphobia, and Suicidal Ideation: The Significance of Comorbid Depressive Symptoms in Veterans with Panic Disorder

Although panic disorder has been frequently associated with increased suicidal ideation and behaviors, there are multiple explanations for this association in the literature. For example, some research has demonstrated panic disorder symptoms to mediate agoraphobia and suicidal ideation, while other researchers have hypothesized that comorbid depression symptoms contribute to suicidal ideation across anxiety disorders. Of note, none of these studies were completed in veterans, a population at higher risk for suicide relative to civilian samples. The present study investigated relations between the symptoms of panic, agoraphobia, depression, and suicidal ideation in 58 veterans diagnosed with panic disorder via correlations, hierarchical regression, and exploratory path analyses. Multiple models were investigated based on prior research. The final path model demonstrated that symptoms of panic disorder predicted agoraphobia symptoms, with agoraphobia predicting symptoms of depression. Symptoms of depression, then, predicted suicidal ideation. Discussion of the findings related to comorbid depressive symptoms highlight considerations for the assessment and treatment practices for panic disorder, with a particular focus on veterans receiving care within Veterans Affairs Healthcare System.

The relationship of separation anxiety with the age of onset of panic disorder

AIM

This study aimed to investigate whether separation anxiety (SA) constitutes a dimension related to age at onset of panic disorder (PD), in homogeneous subgroups of outpatients with PD, based on their age of onset and symptom severity.

METHODS

A sample of 232 outpatients with PD was assessed with the Panic Disorder Severity Scale (PDSS) and the Sheehan Disability Scale (SDS) for functional impairments. Separation anxiety was evaluated using structured interviews and questionnaires. We applied a K-Means Cluster Analysis based on the standardized "PD age of onset" and "the PDSS total score" to identify distinct but homogeneous groups.

RESULTS

We identified three groups of patients: group 1 ("PD early onset/severe", N = 97, 42%, onset 23.2 ± 6.7 years), group 2 ("PD early onset/not severe", N = 76, 33%, onset 23.4 ± 6.0 years) and group 3 ("PD adult onset/not severe", N = 59, 25%, onset 42.8 ± 7.0 years). Patients with early onset/severe PD had significantly higher scores on all SA measures than PD late-onset/not severe. Regression analyses showed that SA scores, but not PDSS scores, were predictive of impairment in SDS work/school, social life, and family functioning domains.

CONCLUSIONS

Our data indicate a significant relationship between SA and PD with an earlier age of onset and an impact on individual functioning. This may have important implications for implementing preventive interventions targeting early risk factors for the subsequent onset of PD.

Molecular Changes Associated with Suicide

Suicide is a serious global public health problem, with a worrying recent increase in suicide rates in both adolescent and adult populations. However, it is essential to recognize that suicide is preventable. A myriad of factors contributes to an individual's vulnerability to suicide. These factors include various potential causes, from psychiatric disorders to genetic and epigenetic alterations. These changes can induce dysfunctions in crucial systems such as the serotonergic, cannabinoid, and hypothalamic-pituitary-adrenal axes. In addition, early life experiences of abuse can profoundly impact an individual's ability to cope with stress, ultimately leading to changes in the inflammatory system, which is a significant risk factor for suicidal behavior. Thus, it is clear that suicidal behavior may result from a confluence of multiple factors. This review examines the primary risk factors associated with suicidal behavior, including psychiatric disorders, early life adversities, and epigenetic modifications. Our goal is to elucidate the molecular changes at the genetic, epigenetic, and molecular levels in the brains of individuals who have taken their own lives and in the plasma and peripheral mononuclear cells of suicide attempters and how these changes may serve as predisposing factors for suicidal tendencies.

Comparison of oxidative stress parameters, thiol-disulfide homeostasis, and pro-inflammatory cytokines levels in patients with bipolar disorder and their first-degree relatives

BACKGROUND

In this study, we aimed to compare the oxidative stress parameters, thiol-disulfide homeostasis, and plasma pro-inflammatory cytokines levels of patients with bipolar disorder (BD), BD patients' first-degree relatives (FDRs), and the healthy controls (HCs).

METHODS

Thirty-five patients with BD, 35 FDRs of BD, and 35 healthy controls (HCs) were included. The individuals' ages varied from 28 to 58, and the groups were well-matched in terms of age and gender. The total thiol (TT), native thiol (NT), disulfide (DIS), total oxidant status (TOS), total antioxidant status (TAS), IL-1β, IL-6, and TNF-α concentrations were measured from serum samples. The oxidative stress index (OSI) was calculated using mathematical formulas.

RESULTS

TOS was significantly higher in both patients and FDRs than HCs (p < 0.01 for all pairwise comparisons). OSI, DIS, oxidized thiol, and the ratio of thiol oxidation-reduction levels were significantly higher in both patients with BD and FDRs than HCs (p < 0.01 for all pairwise comparisons). TAS, TT, NT, and reduced thiol levels were significantly lower in both patients with BD and FDRs than HCs (p < 0.01 for all pairwise comparisons). IL-1β, IL-6, and TNF-α were significantly higher in both patients and FDRs than HCs (p < 0.01 for all pairwise comparisons).

LIMITATIONS

Small sample size.

CONCLUSIONS

Early diagnosis is important for treating of bipolar disorder. TT, NT, DIS, TOS, TAS, OSI, IL1-β, IL-6, and TNF-α can be used as potential biomarkers in the early diagnosis and intervention of BD. Furthermore, oxidative/antioxidative markers and plasma pro-inflammatory cytokine parameters may guide the determination of the disease's activity and response to treatment.

Afraid to go out: Poor quality of life with phobic anxiety in a large cross-sectional adult epilepsy center sample

PURPOSE

People with epilepsy (PWE) have unmet healthcare needs, especially in the context of mental health. Although the current literature has established increased incidence of anxiety and depression in PWE and their contribution to poor quality of life, little is known regarding the presence and impact of specific phobia and agoraphobia. Our aim was to assess factors associated with high phobic/agoraphobic symptoms in a large, single tertiary epilepsy center sample, and to assess their impact on quality of life.

METHODS

In a diverse sample of 420 adults with epilepsy, cross-sectional association of demographic, epilepsy and cognitive factors with high phobic symptoms were assessed using multiple logistic regression. Symptoms were measured with the SCL-90R validated self-report subscale (T-score ≥ 60 considered high phobic symptom group). Multiple logistic regression modeling was used to assess for independent association of demographic and clinical variables with presence of high phobic symptoms, and multiple linear regression modeling was used to evaluate for independent cross-sectional associations with epilepsy-specific quality of life (QOLIE-89).

RESULTS

Lower education (adjusted OR 3.38), non-White race/ethnicity (adjusted OR 2.34), and generalized anxiety symptoms (adjusted OR 1.91) were independently associated with high phobic/agoraphobic symptoms, all p < 0.005. Phobic/agoraphobic symptoms were independently associated with poor quality of life as were depression symptoms, older age, and non-White race/ethnicity. Generalized anxiety did not demonstrate a significant independent association with quality of life in the multivariable model.

CONCLUSION

In this study sample, phobic/agoraphobic symptoms were independently associated with poor quality of life. Clinicians should consider using more global symptom screening instruments with particular attention to susceptible populations, as these impactful symptoms may be overlooked using generalized-anxiety focused screening paradigms.

A retrospective study of psychotropic drug treatments in bipolar disorder at acute and maintenance episodes

BACKGROUND

Bipolar disorder (BD) is predominantly treated with psychotropic drugs, but BD is a complex medical condition and the contribution of psychotropic drugs is not clear. The objectives of this study are: (1) to present psychotropic drugs used in patients with BD; (2) to access changes of psychotropic drug treatments in acute and maintenance episodes.

METHODS

The study retrospectively evaluated the medical records of inpatients in the Ningbo Kangning Hospital from January 2019 to December 2019. The medical history of each subject was collected completely, including sociodemographic (gender, age, marital status, and so on) and clinical characteristics at baseline and within 12 months of admission.

RESULTS

The study ultimately included 204 patients with BD. After 12 months, 73.0% of the patients still took drugs. Mood stabilizers (72-90%) and antipsychotics (77-95%) were still the most important drugs in patients with BD. Antidepressants (34-40%) and benzodiazepines (20-34%) were the other frequently used drug classes. For mood stabilizers, 40-56% of patients were prescribed lithium. For antipsychotic, 54-65% of patients were prescribed quetiapine. Sertraline (6-9%) and fluoxetine (5-9%) were the antidepressant that most frequently prescribed. Lorazepam (10-18%) was the most commonly used benzodiazepine. In psychotropic polypharmacy, the most frequently taken was mood stabilizer plus antipsychotic co-treatment, about 36-44% of all patients. A total of 35-48% of patients treated by two psychotropic drugs and 24-36% received three.

CONCLUSION

The first 6 months after treatment is very important to medication adherence. Mood stabilizers and antipsychotic remained the primary treatment for BD. Antipsychotic is on the rise in the treatment of BD.

Does Conduct, Oppositional Defiant, and Panic Disorder Symptoms Associate with Suicidal Ideations Among African American Adolescents?

Previous studies suggest that mental illness symptoms among adolescents, such as conduct disorder, oppositional defiant disorder, and panic disorder symptoms often associate with suicidal ideations. Despite this, few studies have examined whether these mental illness symptoms associate with suicidal ideations among African American adolescents. To address these limitations, the current study examined whether conduct disorder, oppositional defiant disorder, and panic disorder symptoms associated with suicidal ideations (N = 261). Using binominal logistic regression, results suggest that conduct disorder symptoms were associated with a higher likelihood of endorsing suicidal ideations than oppositional defiant disorder symptoms. Finally, panic disorder symptoms and gender differences were not associated with suicidal ideations. Preventive efforts and psychotherapy implications are discussed.

Redevelopment of mental health first aid guidelines for supporting someone experiencing a panic attack: a Delphi study

Background

Panic attacks and panic disorder can have a major impact on the mental health and wellbeing of those who experience them. People with recurrent panic attacks have increased odds of developing a mental disorder and of worsening the course of existing mental disorders. Early intervention efforts at the time that a panic attack occurs might reduce or prevent some of these associated negative outcomes. Expert consensus guidelines for high income Western countries on how to provide mental health first aid for panic attacks were published in 2009. The present study aims to redevelop these guidelines to ensure content reflects current evidence and best practice.

Methods

The Delphi consensus method was used to determine which helping strategies should be included in the redeveloped guidelines. A survey with items on how to assist someone who is having a panic attack was developed using the 2009 guidelines and a systematic search of grey and academic literature. Panellists with lived experience and professional experience rated these items to determine which helping statements should be included in the guidelines.

Results

Thirty panellists completed all three surveys. Panellists rated 158 statements, with 83 statements meeting the criteria for inclusion in the redeveloped guidelines. The endorsed statements covered: what the first aider should know about panic attacks, what they should do if they think someone is having a panic attack, what they should do if they are uncertain whether the person is having a panic attack, what they should say and do if they know the person is having a panic attack and what they should do when the panic attack has ended.

Conclusion

This study has resulted in a more comprehensive set of guidelines than the original version, with the endorsement of 83 helping actions, compared to 27 previously. The redeveloped guidelines provide greater detail on recognising the signs of a panic attack, providing initial assistance, communicating with someone experiencing a panic attack and supporting them to seek appropriate professional help if it is needed. The guidelines will be used in future updates of Mental Health First Aid training courses.

Suicidality in patients with primary diagnosis of panic disorder: A single-rate meta-analysis and systematic review

BACKGROUND

This study investigated the lifetime suicide attempt and ideation rates among patients with panic disorder (PD).

METHODS

Online databases regarding lifetime suicide attempt and ideation rates in patients with PD were searched up to May 2021.

RESULTS

The suicide attempt and ideation rates were 0.17 (95% CI: 0.16, 0.18) and 0.23 (95% CI: 0.22, 0.25). The suicide attempt rates among female and male patients were 0.17 (95% CI: 0.14, 0.20) and 0.15 (95% CI: 0.12, 0.19). When PD was comorbid with anxiety, depression, substance abuse, and personality disorders, the suicide attempt rates increased to 0.23 (95% CI: 0.20, 0.26), 0.23 (95% CI: 0.18, 0.27), 0.25 (95% CI: 0.20, 0.31), and 0.25 (95% CI: 0.23, 0.28), respectively.

LIMITATIONS

The suicide attempt and ideation by age, suicide ideation by sex, and suicide ideation by comorbidity with other mental disorders were passed in our meta-analysis as sample size was small. Stratification analysis on ethnicity, marital status, education levels, resident location, and severity of PD should be considered in the future.

CONCLUSION

The lifetime suicide ideation and attempt rates in patients with PD were higher than general populations but lower than patients with bipolar or depression. The lifetime suicide attempt rate in female patients was slightly higher than male patients. When PD was comorbid with one other mental illness, the lifetime suicide attempt rate increased by about 50%.

Panic disorder in general medical practice- A narrative review

The under-or misdiagnosis, and symptomatic treatment of the panic disorder (PD), despite high prevalent medical illness, is common among non-psychiatric physicians. The non-psychiatrist physician’s role is vital in the care of PD as most patients initially approach general medical settings for medical help, including primary care. However, a significant proportion is undiagnosed and undergoes either unnecessary investigation, misdiagnosed, or mismanaged even among post-Coronary Artery Bypass Grafting patients, which profoundly affects the patients functioning and quality of life. This article aims to provide overviews of relevant epidemiological aspects, presenting features across medical specialties with respective diagnostic dilemmas, assessment, and management of the PD in their general medical settings, including emergency visits. Apart from psychiatrists, this will also assist non-psychiatrist physicians across all medical specialties, including general practitioners, to understand, identify, and provide the first line evidence-based pharmacotherapy and address the unmet need of patients with PD in their day-to-day busy clinical practice. This paper also provides a referral guide for non-psychiatrist physicians to refer to psychiatrists for further management after their first-line management.

Early Trauma Is Associated With Suicidal Ideation in Patients With Panic Disorder

ABSTRACT

There are several predictors of suicidality in patients with panic disorder (PD). Being a woman, younger age, low education level, unmarried status, and symptom severity have been suggested. This study aimed to examine whether early trauma is associated with suicidal ideation in patients with PD. Our study included 267 patients with PD and 105 controls. Data on sociodemographic variables and data from the Early Trauma Inventory Self Report-Short Form, Beck Depression Inventory, Panic Disorder Severity Scale, Anxiety Sensitivity Inventory-Revised, Coping Scales, and Scale for Suicide Ideation were collected, and correlation and regression analyses were performed. This study suggests that clinicians should consider early trauma when assessing suicidal ideation in patients with PD. Clinicians could consider alternative treatments, such as trauma-focused cognitive-behavioral therapy, eye movement desensitization, reprocessing approaches, and classical pharmacological and psychological treatments for patients with PD who have a history of early trauma and are expected to be at high risk for suicide.

Predictive inflammatory biomarkers for change in suicidal ideation in major depressive disorder and panic disorder: A 12-week follow-up study

Previous studies have investigated the role of inflammatory markers in suicidality of patients with major depressive disorder (MDD) or panic disorder (PD). However, few studies have investigated associations between serum inflammatory cytokine levels and suicidality. We hypothesized that MDD and PD status might be significantly associated with serum inflammatory cytokines and that we could predict levels of improvement in suicide ideation intensity using serum inflammatory biomarkers in patients with MDD and PD. For this study, 41 patients with MDD, 52 patients with PD, and 59 healthy control (HC) subjects were enrolled. Psychological measurements and serum inflammatory markers such as interleukin (IL) -6, -10, interferon (IFN)-γ, tumor necrosis factor (TNF)-α, and C reactive protein (CRP) were examined. A total of five visits were completed during 12 weeks. After controlling for confounding factors, log-transformed IL-6 (ln_IL-6) at baseline (MDD: 0.297 ± 0.626; PD: 0.342 ± 0.723; HC: -0.121 ± 0.858; p = 0.007, >0.0017, 0.05/30) and mean ln_IL-6 (MDD: 0.395 ± 0.550, PD: 0.249 ± 0.544, HC: -0.139 ± 0.622, p = 0.002, >0.0017, 0.05/30) levels were trends towards significantly higher in patients with MDD and PD than in HC. In MDD patients, a higher level of basal ln_TNF-α was a significant predictor of ΔSSI (changes in SSI scores between baseline and week 12) even after controlling for changes of depression symptoms and baseline SSI scores (standardized β = 0.541, p = 0.002 < 0.0028, 0.05/18). In conclusion, we could predict ΔSSI using baseline inflammatory biomarkers for patients with MDD.

Bipolar disorders

Bipolar disorders are a complex group of severe and chronic disorders that includes bipolar I disorder, defined by the presence of a syndromal, manic episode, and bipolar II disorder, defined by the presence of a syndromal, hypomanic episode and a major depressive episode. Bipolar disorders substantially reduce psychosocial functioning and are associated with a loss of approximately 10-20 potential years of life. The mortality gap between populations with bipolar disorders and the general population is principally a result of excess deaths from cardiovascular disease and suicide. Bipolar disorder has a high heritability (approximately 70%). Bipolar disorders share genetic risk alleles with other mental and medical disorders. Bipolar I has a closer genetic association with schizophrenia relative to bipolar II, which has a closer genetic association with major depressive disorder. Although the pathogenesis of bipolar disorders is unknown, implicated processes include disturbances in neuronal-glial plasticity, monoaminergic signalling, inflammatory homoeostasis, cellular metabolic pathways, and mitochondrial function. The high prevalence of childhood maltreatment in people with bipolar disorders and the association between childhood maltreatment and a more complex presentation of bipolar disorder (eg, one including suicidality) highlight the role of adverse environmental exposures on the presentation of bipolar disorders. Although mania defines bipolar I disorder, depressive episodes and symptoms dominate the longitudinal course of, and disproportionately account for morbidity and mortality in, bipolar disorders. Lithium is the gold standard mood-stabilising agent for the treatment of people with bipolar disorders, and has antimanic, antidepressant, and anti-suicide effects. Although antipsychotics are effective in treating mania, few antipsychotics have proven to be effective in bipolar depression. Divalproex and carbamazepine are effective in the treatment of acute mania and lamotrigine is effective at treating and preventing bipolar depression. Antidepressants are widely prescribed for bipolar disorders despite a paucity of compelling evidence for their short-term or long-term efficacy. Moreover, antidepressant prescription in bipolar disorder is associated, in many cases, with mood destabilisation, especially during maintenance treatment. Unfortunately, effective pharmacological treatments for bipolar disorders are not universally available, particularly in low-income and middle-income countries. Targeting medical and psychiatric comorbidity, integrating adjunctive psychosocial treatments, and involving caregivers have been shown to improve health outcomes for people with bipolar disorders. The aim of this Seminar, which is intended mainly for primary care physicians, is to provide an overview of diagnostic, pathogenetic, and treatment considerations in bipolar disorders. Towards the foregoing aim, we review and synthesise evidence on the epidemiology, mechanisms, screening, and treatment of bipolar disorders.
