Important adverse events to be evaluated in antidepressant trials and meta-analyses in depression: a large international preference study including patients and healthcare professionals

Systematic Review and Meta-Analysis: The Association Between Newer-Generation Antidepressants and Insomnia in Children and Adolescents With Major Depressive Disorder

OBJECTIVE

To examine the association between newer generation antidepressants and insomnia as an adverse event (AE) in the treatment of children and adolescents with major depressive disorder (MDD).

METHOD

A systematic search was performed in major databases (inception to August 31, 2023) to retrieve double-blind, placebo-controlled, randomized controlled trials (RCTs) evaluating the safety of 19 antidepressants in the acute treatment (initial 6-12 weeks) of children and adolescents ≤18 years of age with MDD (primary analyses). RCTs in anxiety disorders and obsessive-compulsive disorder (OCD) were retrieved from a recent meta-analysis and included in complementary analyses. A mixed-effects logistic regression model was used to compare the frequency of insomnia in the antidepressant relative to the placebo group. Risk of bias was evaluated using the Cochrane Risk of Bias 2 tool.

RESULTS

In total, 20 trials in MDD (N = 5,357) and 8 trials in anxiety disorders and OCD (N = 1,271) evaluating selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs) were included. In MDD, antidepressant treatment was associated with a modest increase in the odds of insomnia compared with placebo (odds ratio [OR] = 1.65, 95% CI = 1.21-2.27, p = .002), with no significant difference between SSRIs and SNRIs. The RCTs showed low risk of bias or minor concerns for the assessment of insomnia. The odds of treatment-emergent insomnia were significantly lower in MDD (OR = 1.62; 95% CI = 1.21-2.15) compared to anxiety disorders and OCD (OR = 2.89; 95% CI = 1.83-4.57) for treatment with SSRIs (p = .03). Among individual antidepressants with evidence from ≥3 studies, sertraline had the highest OR (3.45; 95% CI = 1.91-6.24), whereas duloxetine had the lowest OR (1.38; 95% CI = 0.79-2.43).

CONCLUSION

Children and adolescents are at a modestly increased risk for experiencing insomnia during the first 6 to 12 weeks of treatment with SSRIs and SNRIs. Antidepressant- and disorder-specific variability in the risk of treatment-emergent insomnia may be relevant to consider in clinical decision making.

Efficacy and safety profile of oral creatine monohydrate in add-on to cognitive-behavioural therapy in depression: An 8-week pilot, double-blind, randomised, placebo-controlled feasibility and exploratory trial in an under-resourced area

Pre-clinical and clinical evidence proposes that creatine monohydrate, an affordable nutraceutical, could be a useful adjunct to conventional antidepressant treatments. In this pilot feasibility and exploratory study, we investigate the 8-week effects of creatine in addition to cognitive-behavioural therapy (CBT) versus placebo plus CBT in depression. For the primary efficacy outcome of change in Patient Health Questionnaire-9 depression score at study endpoint, we used mixed-model repeated measures analysis of covariance. Logistic regressions were employed to assess acceptability (any-cause dropouts), tolerability (dropouts for adverse events), and safety (patients experiencing one or more adverse events). We calculated effect sizes adjusted for age, sex, and baseline depression score. One-hundred participants (50 females, mean age= 30.4 ± 7.4 years) with depression (mean PHQ-9 = 17.6 ± 6.3) were randomised to either creatine+CBT (N = 50) or placebo+CBT (N = 50). At 8 weeks, PHQ-9 scores were lower in both study arms, but significantly more so in participants taking creatine (mean difference= -5.12). Treatment discontinuations due to any cause and to adverse events, and proportion of participants with at least one adverse event were comparable between study arms. This hypothesis-generating trial suggests that creatine could be a useful and safe supplement to CBT for depression. Longer and larger clinical trials are warranted.

An online evidence-based dictionary of common adverse events of antidepressants: a new tool to empower patients and clinicians in their shared decision-making process

BACKGROUND

Adverse events (AEs) are commonly reported in clinical studies using the Medical Dictionary for Regulatory Activities (MedDRA), an international standard for drug safety monitoring. However, the technical language of MedDRA makes it challenging for patients and clinicians to share understanding and therefore to make shared decisions about medical interventions. In this project, people with lived experience of depression and antidepressant treatment worked with clinicians and researchers to co-design an online dictionary of AEs associated with antidepressants, taking into account its ease of use and applicability to real-world settings.

METHODS

Through a pre-defined literature search, we identified MedDRA-coded AEs from randomised controlled trials of antidepressants used in the treatment of depression. In collaboration with the McPin Foundation, four co-design workshops with a lived experience advisory panel (LEAP) and one independent focus group (FG) were conducted to produce user-friendly translations of AE terms. Guiding principles for translation were co-designed with McPin/LEAP members and defined before the finalisation of Clinical Codes (CCs, or non-technical terms to represent specific AE concepts). FG results were thematically analysed using the Framework Method.

RESULTS

Starting from 522 trials identified by the search, 736 MedDRA-coded AE terms were translated into 187 CCs, which balanced key factors identified as important to the LEAP and FG (namely, breadth, specificity, generalisability, patient-understandability and acceptability). Work with the LEAP showed that a user-friendly language of AEs should aim to mitigate stigma, acknowledge the multiple levels of comprehension in 'lay' language and balance the need for semantic accuracy with user-friendliness. Guided by these principles, an online dictionary of AEs was co-designed and made freely available ( https://thesymptomglossary.com ). The digital tool was perceived by the LEAP and FG as a resource which could feasibly improve antidepressant treatment by facilitating the accurate, meaningful expression of preferences about potential harms through a shared decision-making process.

CONCLUSIONS

This dictionary was developed in English around AEs from antidepressants in depression but it can be adapted to different languages and cultural contexts, and can also become a model for other interventions and disorders (i.e., antipsychotics in schizophrenia). Co-designed digital resources may improve the patient experience by helping to deliver personalised information on potential benefits and harms in an evidence-based, preference-sensitive way.

Sexual Dysfunction Induced by Antidepressants-A Pharmacovigilance Study Using Data from VigiBaseTM

Sexual dysfunction is a common side effect of antidepressants, significantly impacting patients' quality of life and treatment adherence. This study investigates the relationship between sexual dysfunction and antidepressants by analyzing data from VigiBase™, the World Health Organization's global database of individual case safety reports. In this study, we examined, for the first time, reports related to sexual response-desire, arousal, and orgasm-by grouping appropriate side effect terms and calculated the reporting odds ratios (RORs) for various antidepressants. The findings of this study highlight a high disproportional reporting of sexual dysfunction, particularly with selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. In contrast, agents such as agomelatine, bupropion, and mirtazapine showed a lower association. Furthermore, we investigated the correlation between reporting odds ratios and the binding affinities of antidepressants to specific neurotransmitter receptors and transporters, unveiling significant relationships that provide insights into the pharmacodynamic pathways underlying these adverse effects. For instance, a positive correlation was observed between the serotonin transporter and side effects in the category desire: r (19) = 0.67, p = 0.001 These insights underscore the necessity for clinicians to consider sexual side effects when prescribing antidepressants and to monitor and address these issues to improve patient outcomes.

Adjunctive brexpiprazole 1 mg and 2 mg daily for Japanese patients with major depressive disorder following inadequate response to antidepressants: a phase 2/3, randomized, double-blind (BLESS) study

AIMS

Inadequate antidepressant response interrupts effective treatment of major depressive disorder (MDD). The BLESS study evaluates the dosage, efficacy, and safety of brexpiprazole adjunctive therapy in Japanese patients with inadequate antidepressant therapy (ADT) response.

METHODS

This placebo-controlled, randomized, multicenter, parallel-group phase 2/3 study randomized Japanese MDD patients (Hamilton Rating Scale for Depression 17-item total score ≥ 14; historical inadequate response to 1-3 ADTs) with inadequate response to 8-week single-blind, prospective SSRI/SNRI treatment to 6-week adjunctive treatment with brexpiprazole 1 mg, 2 mg, or placebo. The primary endpoint was change in Montgomery-Åsberg Depression Rating Scale (MADRS) total score from baseline. Secondary endpoints included MADRS response, remission rate, and Clinical Global Impression-Improvement score. Safety was comprehensively evaluated, especially regarding antipsychotic adverse events (AEs).

RESULTS

Of 1194 screened patients, 740 were randomized and 736 (1 mg, n = 248; 2 mg, n = 245; placebo, n = 243) had ≥1 baseline/post-baseline MADRS total score. The LSM (SE) change from baseline in MADRS total score at Week 6 by MMRM analysis was -8.5 (0.47) with brexpiprazole 1 mg, -8.2 (0.47) with brexpiprazole 2 mg, and -6.7 (0.47) with placebo (placebo-adjusted LSM difference [95% CI]: 1 mg, -1.7 [-3.0, -0.4]; P = 0.0089; 2 mg, -1.4 [-2.7, -0.1]; P = 0.0312). Secondary efficacy results supported the primary endpoint. Brexpiprazole was generally well tolerated.

CONCLUSION

Brexpiprazole 1 mg daily was an appropriate starting dose and both 1 mg and 2 mg daily were effective and well tolerated as adjunctive therapy for Japanese MDD patients not adequately responsive to ADT.

The Effects of Physical Activity, Exercise, and Sports Programs on Depressive Symptoms in Individuals with Disabilities: A Systematic Review with Meta-Analysis

Studies show that physical activity, exercise, or sport reduces depressive symptoms in the general population. However, little is known about its effects on individuals with disabilities. Thus, this systematic review with meta-analysis aims to verify the effects of this practice on depressive symptoms in individuals with disabilities. The Pubmed, Web of Science, Scopus, and SportDiscus databases were used, with several descriptors and Boolean operators. A total of 1509 studies were identified through searching the databases. Studies that met the eligibility criteria were subsequently assessed for their methodological quality (Downs and Black scale), and a meta-analysis was performed. The Z-values that were obtained to test the null hypothesis, which states that there is no difference in means, showed Z = -2.294 and a corresponding p-value = 0.022. We can, therefore, reject the null hypothesis in the sense that exercise seems to reduce depressive symptoms in individuals with disabilities. In sum, participants from the intervention group presented more probability of reducing depressive symptoms when compared to the control group (approximately -1.4 standard differences in means; 95% CI -2.602 to -0.204).

Values and Preferences of Patients With Depressive Disorders Regarding Pharmacologic and Nonpharmacologic Treatments : A Rapid Review

BACKGROUND

Developers of clinical practice guidelines need to take patient values and preferences into consideration when weighing benefits and harms of treatment options for depressive disorder.

PURPOSE

To assess patient values and preferences regarding pharmacologic and nonpharmacologic treatments of depressive disorder.

DATA SOURCES

MEDLINE (Ovid) and PsycINFO (EBSCO) were searched for eligible studies published from 1 January 2014 to 30 November 2022.

STUDY SELECTION

Pairs of reviewers independently screened 30% of search results. The remaining 70% of the abstracts were screened by single reviewers; excluded abstracts were checked by a second reviewer. Pairs of reviewers independently screened full texts.

DATA EXTRACTION

One reviewer extracted data and assessed the certainty of evidence, and a second reviewer checked for completeness and accuracy. Two reviewers independently assessed risk of bias.

DATA SYNTHESIS

The review included 11 studies: 4 randomized controlled trials, 5 cross-sectional studies, and 2 qualitative studies. In 1 randomized controlled trial, participants reported at the start of therapy that they expected supportive-expressive psychotherapy and antidepressants to yield similar improvements. A cross-sectional study reported that non-Hispanic White participants and men generally preferred antidepressants over talk therapy, whereas Hispanic and non-Hispanic Black participants and women generally did not have a preference. Another cross-sectional study reported that the most important nonserious adverse events for patients treated with antidepressants were insomnia, anxiety, fatigue, weight gain, agitation, and sexual dysfunction. For other comparisons and outcomes, no conclusions could be drawn because of the insufficient certainty of evidence.

LIMITATIONS

The main limitation of this review is the low or insufficient certainty of evidence for most outcomes. No evidence was available on second-step depression treatment or differences in values and preferences based on gender, race/ethnicity, age, and depression severity.

CONCLUSION

Low-certainty evidence suggests that there may be some differences in preferences for talk therapy or pharmacologic treatment of depressive disorders based on gender or race/ethnicity. In addition, low-certainty evidence suggests that insomnia, anxiety, fatigue, weight gain, agitation, and sexual dysfunction may be the most important nonserious adverse events for patients treated with antidepressants. Evidence is lacking or insufficient to draw any further conclusions about patients' weighing or valuation of the benefits and harms of depression treatments.

Evidence-based prescribing of medications for ADHD: where are we in 2023?

INTRODUCTION

A large number of randomized controlled trials (RCTs) and observational studies on the pharmacotherapy of ADHD are available.

AREAS COVERED

Based on a search in PubMed and PsycInfo (up to 15 September 2022), this review addresses to which extent this body of research is currently able to inform routine prescribing practice, in terms of the choice of medication, titration strategy, augmentation treatments, and use of alternative, non-approved treatments.

EXPERT OPINION

A growing body of evidence is informing prescribers on some, but certainly not all, aspects related to the pharmacological treatment of ADHD in the daily clinical practice, with important weaknesses/gaps that need to be addressed. First, evidence synthesis of RCTs is not able to inform decision-making at the individual patient level. Second, the maximum safe and effective doses, possibly beyond those currently recommended, are not well understood. Third, evidence from RCTs on augmenting strategies is still limited. Fourth, no novel agents with the same or higher effect size of stimulants, in terms of efficacy, but with better tolerability and lower abuse potential, have been found. Implementation of precision psychiatry approaches and stratification of patients in future RCTs will be key to, respectively, individualize the treatment strategies and test etiopathophysiology-based agents.

Postsynaptic Proteins at Excitatory Synapses in the Brain—Relationship with Depressive Disorders

Depressive disorders (DDs) are an increasingly common health problem that affects all age groups. DDs pathogenesis is multifactorial. However, it was proven that stress is one of the most important environmental factors contributing to the development of these conditions. In recent years, there has been growing interest in the role of the glutamatergic system in the context of pharmacotherapy of DDs. Thus, it has become increasingly important to explore the functioning of excitatory synapses in pathogenesis and pharmacological treatment of psychiatric disorders (including DDs). This knowledge may lead to the description of new mechanisms of depression and indicate new potential targets for the pharmacotherapy of illness. An excitatory synapse is a highly complex and very dynamic structure, containing a vast number of proteins. This review aimed to discuss in detail the role of the key postsynaptic proteins (e.g., NMDAR, AMPAR, mGluR5, PSD-95, Homer, NOS etc.) in the excitatory synapse and to systematize the knowledge about changes that occur in the clinical course of depression and after antidepressant treatment. In addition, a discussion on the potential use of ligands and/or modulators of postsynaptic proteins at the excitatory synapse has been presented.
