A systematic review on the effectiveness of dialectical behavior therapy for improving mood symptoms in bipolar disorders.

BACKGROUND: Evidence-based psychotherapies available to treat patients with bipolar disorders (BD) are limited. Dialectical behavior therapy (DBT) may target several common symptoms of BD. We conducted a systematic review on the efficacy of DBT for mood symptoms in patients with BD. The systematic search used key words related to DBT and BD in Medline, Embase, PsycInfo, CINAHL, and Cochrane Library databases from 1980 to April 1st, 2022. We included studies that enrolled patients with a BD I or II diagnosis (DSM or ICD), age 12 and older who received a DBT-based intervention. Studies reviewed were clinical trials including observational studies that reported at least one outcome related to BD mood symptoms or severity. We did not exclude based upon psychiatric or physical co-morbidity. RESULTS: We screened 848 abstracts and reviewed 28 full texts; 10 publications with 11 studies met our pre-determined eligibility criteria. All but one were feasibility pilot studies and most included participants in all mood states except for mania. The studies provided preliminary evidence suggesting these interventions may be effective for improving several core symptoms of BD. Overall, all the studies consistently supported that DBT-based interventions are feasible and acceptable for patients with BD. CONCLUSION: DBT may be an effective treatment for BD; however, the confidence in this conclusion is limited by the small sample sizes, heterogeneity, and high risk of bias in all published trials. Larger well-designed RCTs are now required to establish the effectiveness of DBT in BD.

Culturally adapted psychoeducation for bipolar disorder in a low-resource setting: protocol for a multicentre randomised controlled trial.

BACKGROUND: Bipolar disorder is a source of marked disability, morbidity and premature death. There is a paucity of research on personalised psychosocial interventions for bipolar disorder, especially in low-resource settings. A pilot randomised controlled trial (RCT) of a culturally adapted psychoeducation intervention for bipolar disorder (CaPE) in Pakistan reported higher patient satisfaction, enhanced medication adherence, knowledge and attitudes regarding bipolar disorder, and improvement in mood symptom scores and health-related quality of life measures compared with treatment as usual (TAU). AIMS: The current protocol describes a larger multicentre RCT to confirm the clinical and cost-effectiveness of CaPE in Pakistan. Trial registration: NCT05223959. METHOD: A multicentre individual, parallel-arm RCT of CaPE in 300 Pakistani adults with bipolar disorder. Participants over the age of 18, with a diagnosis of bipolar I or II disorder who are currently euthymic, will be recruited from seven sites: Karachi, Lahore, Multan, Rawalpindi, Peshawar, Hyderabad and Quetta. Time to recurrence will be the primary outcome assessed using the Longitudinal Interval Follow-up Evaluation (LIFE). Secondary measures will include mood symptoms, quality of life and functioning, adherence to psychotropic medications, and knowledge and attitudes regarding bipolar disorder. RESULTS: This trial will assess the effectiveness of the CaPE intervention compared with TAU in reducing the time to recurrence for people with bipolar disorder currently in remission in Pakistan and determine the effect on clinical outcomes, quality of life and functioning. CONCLUSIONS: A successful trial might lead to rapid implementation of CaPE in clinical practice, not only in Pakistan, but also in other low-resource settings, including those in high-income countries, to improve clinical outcomes, social and occupational functioning, and quality of life in South Asian and other minority group patients with bipolar disorder.

Efficacy and acceptability of pharmacotherapy for comorbid anxiety symptoms in bipolar disorder: A systematic review and meta-analysis.

OBJECTIVE: Anxiety symptoms are highly prevalent among individuals with bipolar disorder (BD) but there is little guidance on pharmacotherapy for these symptoms. The objective of this systematic review and meta-analysis was to evaluate the available evidence for pharmacotherapy of comorbid anxiety symptoms in BD. METHODS: Completed randomized clinical trials (RCTs) of medications for BD published prior to December 2020 were identified through a systematic search of MEDLINE, Embase, PsycInfo, Web of Science, clinicaltrials.gov, and the ISRCTN. Data from RCTs measuring anxiety symptoms at baseline and endpoint and all-cause discontinuation were pooled to compare the efficacy and acceptability of medications with control conditions. RESULTS: Thirty-seven RCTs met our inclusion criteria; 13 placebo-controlled RCTs with 2175 participants had sufficient data to be included in the meta-analysis assessing anxiety symptoms. Compared with placebo, the overall effect size of medications (primarily atypical antipsychotics) on anxiety symptoms was small with a standardized mean difference (SMD) = -0.22 (95% CI: -0.34 to -0.11). Study heterogeneity was low (I2  = 26%). The acceptability of these medications was comparable with placebo with odds ratio of discontinuation from all causes = 0.98 (95% CI: 0.91-1.06). CONCLUSION: There is limited evidence for a small anxiolytic effect and good acceptability of pharmacotherapy (primarily atypical antipsychotics) in the treatment of comorbid anxiety symptoms in BD. These results highlight the need for further research on medications other than atypical antipsychotics.

Relationship between childhood trauma, personality, social support and depression in women attending general medical clinics in a low and middle-income country.

BACKGROUND: Associations between childhood trauma, personality, and Major Depressive Disorder (MDD) have been well established in studies conducted in high-income countries. However, there are limited studies on these associations in low and middle-income countries (LMICs), where MDD is highly prevalent. We assessed the relationships between childhood trauma, personality, and MDD in women in Karachi, Pakistan. METHOD: In this cross-sectional study of 455 female patients attending general medical outpatient clinics, a diagnosis of MDD was confirmed using the Structured Clinical Interview for DSM-IV (SCID); retrospective reports of childhood trauma were collected using the childhood trauma questionnaire (CTQ); and Big Five personality traits were assessed using the NEO Personality Inventory Revised (NEO PI-R). Other measures included the Life Events Questionnaire (LEQ) and the Multidimensional Scale of Perceived Social Support (MSPSS). Factors independently associated with MDD were determined using logistic regression analyses. RESULTS: Of the 455 women recruited between August 1, 2011 and July 31, 2013, 242 (53%) had a diagnosis of MDD. Women with MDD were significantly more likely to be separated, had more stressful life events and higher CTQ scores. Higher perceived social support, conscientiousness and extraversion were independently associated with significantly reduced odds of MDD. There were no significant associations between CTQ scores and any of the NEO PI-R subscales. LIMITATIONS: Ratings of childhood trauma were based on retrospective recall. CONCLUSION: MDD and a history of childhood trauma were highly prevalent in Pakistani women attending general medical clinics. Interventions to prevent childhood trauma and promote social support in women may improve public mental health in LMICs like Pakistan.

Stigma toward mental and physical illness: attitudes of healthcare professionals, healthcare students and the general public in Pakistan.

BACKGROUND: The evidence base for stigma in mental health largely originates from high-income countries. AIMS: This study from Pakistan aimed to address the gap in literature on stigma from low- and middle-income countries. METHOD: This cross-sectional study surveyed 1470 adults from Karachi, Pakistan. Participants from three groups (healthcare professionals, healthcare students and the general public) completed the adapted Bogardus Social Distance Scale (SDS) as a measure of stigma. RESULTS: All three groups reported higher scores of stigma toward mental disorders compared with physical disorders. SDS scores for mental illness in the general public were significantly higher than in healthcare students (mean difference (MD) 6.93, 95% CI 5.45-8.45, P < 0.001) and healthcare professionals (MD 6.93, 95% CI 5.48-8.38, P < 0.001). However, SDS scores between healthcare students and healthcare professionals were not significantly different (MD 0.003, 95% CI -1.14-1.14, P > 0.99). Being female was associated with lower stigma scores and being over the age of 30 years was associated with higher stigma scores. CONCLUSIONS: Stigma campaigns in Pakistan need to target the general population. However, evidence of negative attitudes toward mental illness in healthcare students and healthcare professionals supports the need for stronger emphasis on psychiatric education within undergraduate and postgraduate training in Pakistan.

Minocycline as adjunctive treatment for treatment-resistant depression: study protocol for a double blind, placebo-controlled, randomized trial (MINDEP2).

BACKGROUND: Available evidence suggests that adjunctive treatment with immunomodulatory medications may be effective in the treatment of major depressive disorder (MDD). A pilot trial of the tetracycline minocycline as adjunctive treatment in treatment-resistant depression (TRD), produced promising results, however, a larger scale trial is needed to confirm the antidepressant actions of this drug. METHODS: This is a 12-week double blind, placebo-controlled, randomized trial of minocycline as an add-on to standard antidepressants for adults (age > 18) with DSM-5 major depressive episode, who have failed to respond to at least two adequate trials of antidepressant treatment. It is a parallel-arm study with 50 participants in each group. The primary outcome measure is change in 17-item Hamilton Depression Rating Scale (HRSD-17) total scores from baseline to week 12. Secondary measures include the Clinical Global Impression (CGI) scale, World Health Organization Quality of Life Short Version (WHOQOL-BREF) and the Generalized Anxiety Disorder scale (GAD-7). Peripheral inflammatory biomarkers will be collected at baseline, week 6 and 12. DISCUSSION: If minocycline is well tolerated and effective in reducing depressive symptoms in patients with TRD, it would warrant genuine consideration as a treatment option for TRD. Additionally, if results demonstrate that minocycline has antidepressant properties, and that changes in inflammatory status are associated with its antidepressant action, it will inform the development of individualized treatment for a subset of patients with MDD. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03947827. Registered 13th May, 2019.

Demographic and psychosocial characteristics of self-harm: The Pakistan perspective.

Self-harm is a major public health issue in Pakistan, yet the characteristics of those who self-harm are under-explored. This is a secondary analysis from a large randomized control trial on the prevention of self-harm, exploring demographic, clinical and psychological characteristics of people who self-harm in Pakistan. A total of 221 participants with a history of self-harm were recruited from medical wards of three major hospitals in Karachi. The Beck Scale for Suicidal Ideation (BSI), Beck Depression Inventory (BDI), Beck Hopelessness Scale (BHS), and Suicide Attempt Self Injury Interview (SASII) assessment scales were completed. The sample consisted predominantly of females (68.8%) in their 20's. Interpersonal difficulties were most commonly reported as the main antecedent to the self-harm, followed by financial difficulties. Participants had high severity scores on BSI, BDI and BHS. Pesticide and insecticide use were (n = 167, 75.6%) the most common methods of self-harm. The findings indicate that some characteristics of those who self-harm in Pakistan are comparable to other populations. This may raise the possibility of common causal mechanisms and processes. Future research needs to examine the efficacy of interventions targeting these risk factors in reducing rates of self-harm and thus suicide.
