Double-blind and placebo-controlled study of lithium for adolescent bipolar disorders with secondary substance dependency

Early Life Stress and Substance Use Disorders: Underlying Neurobiology and Pathways to Adverse Outcomes

Early life stress (ELS) has been established as a major risk factor for a multitude of psychiatric and medical disorders. ELS is highly prevalent in the general population and constitutes a major public health concern. The current review will focus on the clinical literature that suggests a link between adverse early life experiences and vulnerability for adolescent and adult substance use disorders. It will investigate the characteristics of ELS that appear to increase risk for disorder onset and a more severe disease course, characterized by earlier onset, greater risk of relapse, and treatment resistance. The authors explore how ELS may increase risk for adverse substance use outcomes through long-lasting changes in the HPA axis and development of stress, reward, and executive control brain systems. The review will also discuss potential pathways to substance use disorder following ELS, with a focus on the role of comorbid mood and anxiety disorders and other modifiable traits. Finally, the authors will discuss how the current body of work presents the potential for prevention and intervention strategies to reduce the psychosocial consequences following early life stress and minimize adverse substance use outcomes.

Co-Occurring Bipolar and Substance Use Disorders: A Review of Impacts, Biopsychosocial Mechanisms, Assessment, and Treatment

Individuals with bipolar disorder are at significant risk for having a co-occurring substance use disorder-particularly, alcohol and cannabis use disorders. Having a co-occurring substance use disorder is associated with a more pernicious clinical course, lower quality of life, and poorer treatment outcomes. Despite its increased morbidity, there is little research and clinical evidence-based guidelines on the treatment of individuals with co-occurring bipolar and substance use disorders. This review details current knowledge on the prevalence, clinical correlates, and biopsychosocial mechanisms underlying co-occurring bipolar and substance use disorders. The authors present recent research that highlights underlying mechanisms of comorbidity, including aberrant reward processing, stress sensitization, early childhood maltreatment, and gene-environment interactions. Next, the authors review current evidence-based recommendations for the assessment and treatment of co-occurring bipolar and substance use disorder, highlighting areas of needed future clinical research.

Pediatric Bipolar Disorder: Challenges in Diagnosis and Treatment

Despite an opportunity to prevent adult psychopathology associated with bipolar disorder through early diagnosis in children, there is insufficient information and awareness among healthcare providers about the unique features and treatment of mania and its comorbid conditions in children. Converging evidence from disparate sites describe a developmentally distinct presentation of bipolar disorder in youth that is highly morbid, persistent and responds to treatment with the mood stabilizer medications used in the treatment of adult bipolar disorder, such as divalproex sodium and carbamazepine. Some are additionally approved for use in pediatric populations including, for manic or mixed states, risperidone, aripiprazole, and asenapine for those aged 10-17 years and also including lithium and olanzapine for ages 13-17 years. Quetiapine is approved as monotherapy or as adjunct to lithium or divalproex sodium for manic states in those aged 10-17 years. Delayed or missed diagnosis, inappropriate treatment, worsening course, and treatment resistance unfortunately still occur. While an array of mood-stabilizing medications is available for treatment, such as second-generation antipsychotics, lithium, and anticonvulsants, these can be only partially effective and fraught with annoying and serious side effects. This article will review current practice in the diagnosis and treatment of pediatric bipolar disorder and its comorbid conditions, highlighting areas of need for future research.

Correlates of cannabis use and cannabis use disorder among adolescents with major depressive disorder and bipolar disorder in the National Comorbidity Survey-Adolescent Supplement (NCS-A)

BACKGROUND

Despite evidence regarding prevalence and correlates of cannabis use (CU) and cannabis use disorder (CUD) in major depressive disorder (MDD) and bipolar disorder (BD) in adults, little is known about this topic among adolescents.

METHODS

Data are from the 2001-2004 National Comorbidity Survey-Adolescent Supplement, an in-person, cross-sectional epidemiologic survey of mental disorders. Participants included adolescents, ages 13-18 years, with MDD (n = 354 with CU, n = 70 with CUD, n = 688 with no CU), BD (n = 79 with CU, n = 32 with CUD, n = 184 with no CU), or adolescents without mood disorders (n = 1413 with CU, n = 333 with CUD, n = 6970 with no CU). Analyses examined prevalence and correlates of CU and CUD within MDD and BD groups.

RESULTS

CU was most prevalent in adolescents with MDD followed by adolescents with BD then controls. CUD was most prevalent in adolescents with BD followed by adolescents with MDD then controls. In covariate-adjusted ordinal logistic regression models, within MDD and BD, CU and CUD groups had significantly higher odds of lifetime suicidal ideation/attempts, as well as other significant indicators of clinical severity.

LIMITATIONS

Based on changes in cannabis acceptance, potency, and availability in the two decades since this study was conducted, present findings may underestimate adverse cannabis associations.

CONCLUSION

CU and CUD are both associated with adverse clinical characteristics in a community-based sample of adolescents with MDD and BD. Evidence that risks of cannabis use extend across the spectrum of use is important for adolescents with MDD and BD, in whom cannabis-related consequences tend to be more severe.

A Double-Blind, Placebo-Controlled Study of Adjunctive Topiramate in Adolescents With Co-Occurring Bipolar and Cannabis Use Disorders

Objective

To evaluate the efficacy of adjunctive topiramate (TPM) for the treatment of cannabis use disorder in adolescents with bipolar I disorder.

Method

We conducted a 16-week, double-blind, randomized, placebo-controlled investigation of quetiapine plus TPM (median dose = 208 mg) vs quetiapine plus placebo in adolescents with bipolar I and cannabis use disorder. All subjects participated in a Motivational Interview and Compliance Enhancement Therapy. The primary outcome measure was change in weekly cannabis use over a 16-week treatment period using the Timeline Followback. The secondary outcome measure was the baseline-to-endpoint total score change in the Young Mania Rating Scale (YMRS).

Results

A total of 75 participants completed at least 1 post-baseline assessment (TPM = 38, placebo = 37). There was a significant time-by-treatment effect over the 16-week treatment period, with baseline-adjusted treatment differences in favor of the TPM group over time (p < .001). Although there was no difference in baseline-to-endpoint YMRS total score change between groups (p = .342), there was as significant decline in YMRS total score within both groups (p < .0001). There was a significant positive effect for alcohol use (p < .001) and nicotine use (p = .033) in the TPM group. More participants in the TPM group experienced appetite decrease (p = .032) and excitement (p = .025). Participants in the placebo group experienced greater weight gain (p = .010).

Conclusion

Treatment with TPM adjunctive to quetiapine and a Motivational Interview and Compliance Enhancement Therapy is associated with a greater decrease in cannabis use and less weight gain. TPM is a well-tolerated and efficacious treatment for cannabis use disorder in adolescents with bipolar I disorder.

Advances in the management of bipolar disorder in children and adolescents: an update on the literature

INTRODUCTION

Early diagnosis and treatment concerning bipolar disorder (BD) are related to a better functioning over the long-term period. Although pharmacotherapy is indicated for approximately all youths with BD, nearly one-third of patients do not receive adequate medications for their condition.

AREAS COVERED

The authors discuss the available scientific evidence from the current literature about the management of BD in both children and adolescents, giving particular focus to the efficacy and tolerability of the available pharmacological agents. Studies were identified searching MEDLINE and retrieved from reference listings of relevant articles and through consultation with experts in the field.

EXPERT OPINION

Many D2-blockers, approved by the Food and Drug Administration (FDA) based on their antimanic properties in youths, are related to both short- and long-term side effects. Lurasidone was found to be effective for the treatment of acute juvenile bipolar depression, while lithium for the treatment and recurrence prevention of manic/mixed episodes. The most common anticonvulsants were found to be most useful as adjunctive antimanic agents in non-responders to first-line monotherapies. No data was found to support the use of antidepressants in juvenile BD.

A systematic review of evidence on integrated management of psychiatric disorders in youth who use cannabis

Given the risks to mental health associated with cannabis use in youth and the increase in cannabis legalization worldwide and in the U.S., there is a need to understand existing evidence-based approaches to integrated management of psychiatric disorders in youth who use cannabis. This systematic review aimed to appraise the current evidence on integrated treatment for adolescents and young adults with common psychiatric disorders who engage in regular cannabis use. A total of 989 studies were screened for inclusion. Study's titles and abstracts were screened and advanced to full text review for further screening by two independent reviewers. Thirty-five full-text articles were reviewed, with five articles ultimately meeting all criteria for inclusion. Five randomized controlled trials examined the effects of therapeutic interventions in youth with common psychiatric disorders who used cannabis, including two studies on depression, one on bipolar disorder, one on anxiety and one on PTSD were reviewed. No studies were considered high in risk of bias. Overall, there is a paucity of research on the treatment of comorbid adolescent mental health disorders and cannabis use, which limits the ability to draw evidence-based treatment recommendations.

The CANMAT and ISBD Guidelines for the Treatment of Bipolar Disorder: Summary and a 2023 Update of Evidence

Bipolar disorder is a complex and heterogeneous psychiatric condition that affects more than 2% of the population. The assessment and treatment of bipolar disorder can be a challenge for clinicians, given its clinical complexity and the rapidly changing treatment landscape with the growing range of treatment options that are becoming available for various phases of the illness. To help clinicians navigate the complexity involved in the assessment and management of bipolar disorder, the guidelines of the 2018 Canadian Network for Mood and Anxiety Treatments (CANMAT) and International Society for Bipolar Disorders (ISBD) synthesized the evidence on the efficacy, safety, and tolerability of treatments for bipolar disorder and translated it into first-, second-, and third-line treatment recommendations. The main objective of this contribution is to provide clinicians with a summary of the 2018 CANMAT/ISBD guideline recommendations with the addition of any new evidence for the treatment of bipolar disorder across the lifespan.

Re-Purposing FDA-Approved Drugs for Opioid Use Disorder

OBJECTIVE

To investigate FDA-approved drugs prescribed for unrelated diseases or conditions that promote remission in subjects diagnosed with opioid use disorder (OUD).

METHODS

This was a retrospective observational study utilizing the TriNetX electronic medical record data. Subjects between 18 and 65 years old were included in this study. First, a drug screen was employed to identify medications used for chronic illness that are associated with OUD remission. Based on Fisher's exact test for significance, 28 of 101 medications were selected for further analysis. Positive (buprenorphine/methadone) and negative controls (benazepril) were included in the analysis. Medications were analyzed in the absence and presence of buprenorphine or methadone, two medications used to treat OUD, to identify the likelihood of OUD remission up to one year following the index event.

RESULTS

We identify 8 medications (prazosin, propranolol, lithium carbonate, olanzapine, quetiapine, bupropion, citalopram, and escitalopram) that may be useful for increasing remission in OUD in the absence of buprenorphine or methadone. Additionally, our results identify psychiatric medications that when taken alongside buprenorphine and methadone improve remission rates.

CONCLUSION

These results provide medication options that may be useful in treating OUD as well as integrated therapies to treat comorbid mental illness.

Pharmacological Strategies for Bipolar Disorders in Acute Phases and Chronic Management with a Special Focus on Lithium, Valproic Acid, and Atypical Antipsychotics

Bipolar disorders (BDs) are a heterogeneous group of severe affective disorders generally described by the alternation of (hypo)manic, depressive, and mixed phases, with euthymic intervals of variable duration. BDs are burdened with high psychiatric and physical comorbidity, increased suicide risk and reduced life expectancy. In addition, BDs can progress into complicated forms (e.g., mixed states, rapid/irregular cycling), which are more difficult to treat and often require personalized pharmacological combinations. Mood stabilizers, particularly Lithium and Valproic acid (VPA), still represent the cornerstones of both acute and chronic pharmacotherapies of BDs. Lithium is the gold standard in BD-I and BDII with typical features, while VPA seems more effective for atypical forms (e.g., mixed-prevalence and rapid-cycling). However, despite appropriate mood stabilization, many patients show residual symptoms, and more than a half recur within 1-2 years, highlighting the need of additional strategies. Among these, the association of atypical antipsychotics (AAPs) with mood stabilizers is recurrent in the treatment of acute phases, but it is also being growingly explored in the maintenance pharmacotherapy. These combinations are clinically more aggressive and often needed in the acute phases, whereas simplifying pharmacotherapies to mood stabilizers only is preferable in the long-term, whenever possible. When mood stabilizers are not enough for maintenance treatment, Quetiapine and, less consistently, Aripiprazole have been proposed as the most advisable adjunctive strategies, for their safety and tolerability profiles. However, in view of the increased risk of serious adverse effects, a careful patient-centered balance between costs and benefits is mandatory.

Triple Diagnosis of Attention-Deficit/Hyperactivity Disorder with Coexisting Bipolar and Alcohol Use Disorders: Clinical Aspects and Pharmacological Treatments

Attention-Deficit/Hyperactivity Disorder (ADHD), Bipolar Disorder (BD) and Alcohol Use Disorder (AUD) are common medical conditions often coexisting and exerting mutual influence on disease course and pharmacological treatment response. Each disorder, when considered separately, relies on different therapeutic approaches, making it crucial to detect the plausible association between them. Treating solely the emerging condition (e.g., alcoholism) and disregarding the patient's whole psychopathological ground often leads to treatment failure and relapse. Clinical experience and scientific evidence rather show that tailoring treatments for these three conditions considering their co-occurrence as a sole complex disorder yields more fulfilling and durable clinical outcomes. In light of the above considerations, the purpose of the present review is to critically discuss the pharmacological strategies in the personalized treatment of complex conditions defined by ADHD-bipolarityalcoholism coexistence.

Use of Lithium in Pediatric Bipolar Disorders and Externalizing Childhood- related Disorders: A Systematic Review of Randomized Controlled Trials

BACKGROUND

Lithium is the standard treatment for bipolar disorders (BD) in adults. There is a dearth of data on its use in the pediatric age. This review aimed to investigate the use of lithium in pediatric bipolar disorder (BD) and other externalizing childhood-related disorders.

METHODS

We applied the Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria (PRISMA) to identify randomized controlled trials evaluating the use of lithium in pediatric (BD), conduct disorder (CD), attention deficit hyperactivity disorder, oppositional defiant disorder, and disruptive mood dysregulation disorder. The primary outcome of our study was to evaluate the efficacy of lithium compared to a placebo or other pharmacological agents. The secondary outcomes were acceptability and tolerability.

RESULTS

Twelve studies were eligible, 8 on BD and 4 on CD. Overall, 857 patients were treated with lithium. No studies for externalizing disorder diagnoses were identified. Regarding BD patients (n = 673), efficacy results suggested that lithium was superior to placebo in manic/mixed episodes but inferior to antipsychotics. Lithium efficacy ranged from 32% to 82.4%. Results on maintenance need to be expanded. Comorbidity rates with other externalizing disorders were extremely high, up to 98.6%. Results in CD patients (n= 184) suggested the efficacy of lithium, especially for aggressive behaviors. No severe adverse events directly related to lithium were reported in BD and CD; common side effects were similar to adults.

CONCLUSION

This systematic review supports the use of lithium in BD and CD as an efficacious and generally well-tolerated treatment in the pediatric age. However, evidence is limited due to the paucity of available data.

Comorbidities in Youth with Bipolar Disorder: Clinical Features and Pharmacological Management

BACKGROUND

Bipolar Disorder (BD) is a highly comorbid condition, and rates of cooccurring disorders are even higher in youth. Comorbid disorders strongly affect clinical presentation, natural course, prognosis, and treatment.

METHODS

This review focuses on the clinical and treatment implications of the comorbidity between BD and Attention-Deficit/Hyperactivity Disorder, disruptive behavior disorders (Oppositional Defiant Disorder and/or Conduct Disorder), alcohol and substance use disorders, Autism Spectrum Disorder, anxiety disorders, Obsessive-Compulsive Disorder, and eating disorders.

RESULTS

These associations define specific conditions which are not simply a sum of different clinical pictures, but occur as distinct and complex combinations with specific developmental pathways over time and selective therapeutic requirements. Pharmacological treatments can improve these clinical pictures by addressing the comorbid conditions, though the same treatments may also worsen BD by inducing manic or depressive switches.

CONCLUSION

The timely identification of BD comorbidities may have relevant clinical implications in terms of symptomatology, course, treatment and outcome. Specific studies addressing the pharmacological management of BD and comorbidities are still scarce, and information is particularly lacking in children and adolescents; for this reason, the present review also included studies conducted on adult samples. Developmentally-sensitive controlled clinical trials are thus warranted to improve the prognosis of these highly complex patients, requiring timely and finely personalized therapies.

Psychopharmacological Treatment Algorithms of Manic/Mixed and Depressed Episodes in Pediatric Bipolar Disorder

Introduction: Pediatric bipolar disorder (PBD) is a severe psychiatric illness diagnosed before the age of 18, which is associated with extreme shifts in mood characterized by manic and depressive episodes. In 2005, AACAP published algorithms to guide pharmacological treatment of manic/mixed episodes associated with PBD. At that time, lithium was the only Food and Drug Administration (FDA)-approved treatment for pediatric bipolar manic/mixed episodes. The goal of this article is to review evidence that has emerged since the AACAP algorithm in 2005. Methods: Literature searches were conducted through PubMed and limited to studies published between 2005 and 2021, using keywords that focused on randomized controlled trials (RCTs) for available psychopharmacological medications. In addition, the authors conducted in-depth searches for articles providing evidence for agents included in the 2005 AACAP algorithm. Results: Since the publication of the AACAP algorithm in 2005, multiple RCTs have been conducted in PBD, leading to FDA approval of five medications (aripiprazole, asenapine, olanzapine, quetiapine, and risperidone) for the treatment of manic/mixed episodes and two medications (lurasidone and olanzapine-fluoxetine combination) for the treatment of depressed episodes. Divalproex sodium and oxcarbazepine were studied in pediatric RCTs and failed to separate from placebo. Conclusions: We offer an update to the 2005 AACAP algorithms for the treatment of pediatric bipolar mixed/manic episodes and added an evidence-based algorithm for the treatment of depression in PBD. In addition to treatment algorithms, we review current evidence for efficacy of agents proposed in the AACAP algorithm and provide tables summarizing medication side effects and efficacy.

Why lithium should be used in patients with bipolar disorder? A scoping review and an expert opinion paper

INTRODUCTION

Lithium treatment is considered the gold standard for the long-term management of bipolar disorder and recurrent unipolar depression. It is also extremely effective in other psychiatric conditions characterized by impulsivity and aggression, and for the prevention of suicidal behaviours.

AREAS COVERED

This paper provides a scoping review and an expert commentary regarding the use of lithium in adult patients. Available information about efficacy, tolerability, dosing, and switching is analyzed, and the strategies that may be most useful in real-world clinical settings are highlighted.

EXPERT OPINION

Lithium is effective on different domains of bipolar disorder, including the long-term prevention of recurrences of affective episodes, management of acute mania as well as in the prophylaxis of all affective episodes. Lithium has been defined a 'forgotten drug,' since its use in routine clinical practice has been declined over the last 20 or 30 years. Reasons for this trend include lack of adequate training on the management of lithium side effects. Considering its efficacy, use of lithium in ordinary clinical practice should be promoted. Several strategies, such as using slow-release formulations, can be easily implemented in order to minimize lithium side effects and improve its tolerability profile.

Prevalence and association of comorbid substance dependence on the course and outcome of bipolar disorder: Findings from the bipolar disorder course and outcome study from India (BiD-CoIN study)

AIM

To evaluate the prevalence of substance use disorder (SUD) and its association with the course and outcome of bipolar disorder (BD).

MATERIALS AND METHODS

A total of 773 patients with BD were recruited from 14 centers in different parts of India, and they were evaluated for the prevalence of comorbid substance dependence, course and outcome, subjective cognitive functioning, and disability.

RESULTS

About one-fourth (22.9%) of the participants had one or more substance dependence. In terms of specific substance of abuse, 136 (17.6%) had nicotine dependence, 80 (10.3%) patients had alcohol dependence, 13 (1.7%) had cannabis dependence, and nine (1.2%) had opioid dependence. Compared to those without comorbid substance dependence, those with a dual diagnosis (i.e., using at least one substance in a dependent pattern) were less educated, more often males, more often currently single, more often employed, had a lower number of depressive episodes per year of illness, had a higher number of manic and mixed episodes per year of illness in the first 5 years of illness, had a higher level of disability, and more often had a history of hospitalization and a history of receiving electroconvulsive therapy (ECT); also, a higher proportion of them had manic predominant polarity, more often had recurrent mania course, and were more often receiving a combination of lithium and valproate.

CONCLUSION

About one-fourth of BD patients have comorbid SUDs, and presence of SUD has a negative impact on the course and outcome of BD.

The pharmacotherapeutic management of comorbid bipolar disorder and alcohol use disorder

INTRODUCTION

Comorbidity of bipolar disorder (BD) and alcohol use disorder (AUD) is very frequent resulting in detrimental outcomes, including increased mortality. Diagnosis of AUD in BD and vice versa is often delayed as symptoms of one disorder mimic and obscure the other one. Evidence for pharmacotherapies for people with comorbid BD and AUD remains limited, and further proof-of-concept studies are urgently needed.

AREAS COVERED

This paper explores the currently available pharmacotherapies for AUD, BD and their usefulness for comorbid BD and AUD. It also covers to some degree the epidemiology, diagnosis, and potential common neurobiological traits of comorbid BD and AUD.

EXPERT OPINION

The authors conclude that more controlled studies are needed before evidence-based guidance can be drawn up for clinician's use. Since there are no relevant pharmacological interactions, approved medications for AUD can also be used safely in BD. For mood stabilization, lithium should be considered first in adherent persons with BD and comorbid AUD. Alternatives include valproate, lamotrigine, and some atypical antipsychotics, with partial D2/D3 receptor agonism possibly being beneficial in AUD, too.

Pharmacologic Treatment and Management of Bipolar Disorder in Adolescents

INTRODUCTION

The importance of the appropriate therapeutic interventions in children and adolescents with bipolar disorder (BD) cannot be overstated since treatment choices and their consequences may have effects into adulthood.

AREAS COVERED

Randomized clinical trials (RCTs) investigating treatment of mania, bipolar depression, and maintenance in adolescents with BD are reviewed. When RCTs are not available or are inadequate, naturalistic data or open studies are also reviewed.

EXPERT OPINION

Efficacy and safety of pharmaceutical agents in adolescents with BD appear to mirror adults with BD. Lithium/mood stabilizers are preferred first line agents over antipsychotic medications, but the latter are second line agents particularly in bipolar depression. When lithium is used, serum levels approaching 1.0 mEq/L are reasonable since younger people appear to require/tolerate higher levels. Among the antipsychotics, quetiapine appeared to be minimally better than risperidone while risperidone was associated with greater adverse events. Antipsychotics with antidepressant activity in adults, also appear to have antidepressant effects in youths. Use of antidepressants in bipolar depression is generally not recommended although it may be reasonable in specific clinical situations. The similarities between adolescent and adult outcomes suggest that it is reasonable to utilize adult data to aid with clinical decision making in adolescents with BD, especially when pediatric-specific data are unavailable.

Pharmacotherapy interventions for adolescent co-occurring substance use and mental health disorders: a systematic review

BACKGROUND

Co-occurring mental health and substance use (SU) disorders among adolescents are common, with two-thirds of adolescents who seek SU treatment also requiring support for mental health. Primary care physicians play a key role in the pharmacological treatment of mental health disorders among adolescents, however, little is known about the impact of these treatments on SU outcomes.

OBJECTIVES

This systematic review summarizes the evidence regarding commonly used pharmacotherapy interventions for mental health and their impact on adolescent SU.

METHODS

Literature searches were conducted across five databases as part of a larger systematic review of adolescent SU interventions. Studies were screened for eligibility by two researchers, and study data were extracted regarding study design, patient and treatment characteristics and results. Risk of bias analyses and qualitative syntheses were completed to evaluate the strength of the evidence and the impact of pharmacotherapy on SU outcomes.

RESULTS

Ten randomized controlled trials exploring seven pharmacotherapies met criteria for inclusion. All studies had low to moderate risk of bias. Four studies evaluated pharmacotherapy for co-occurring depression and SU, three evaluated attention deficit hyperactivity disorder and SU, and three evaluated bipolar disorder and SU. Five of the 10 studies also included a behavioural intervention. We found no evidence that pharmacotherapy for co-occurring mental health diagnoses impacted SU.

CONCLUSION

Family medicine clinicians prescribing pharmacotherapy for mental health should be aware that additional interventions will likely be needed to address co-occurring SU.

Research Status in Clinical Practice Regarding Pediatric and Adolescent Bipolar Disorders

Bipolar disorders (BDs) have high morbidity. The first onset of 27.7% of BDs occurs in children under 13 years and of 37.6% occurs in adolescents between 13 and 18 years. However, not all of the pediatric and adolescent patients with BD receive therapy in time. Therefore, studies about pediatric and adolescent patients with disorders have aroused increased attention in the scientific community. Pediatric and adolescent patients with BD present with a high prevalence rate (0.9-3.9%), and the pathogenic factors are mostly due to genetics and the environment; however, the pathological mechanisms remain unclear. Pediatric and adolescent patients with BD manifest differently from adults with BDs and the use of scales can be helpful for diagnosis and treatment evaluation. Pediatric and adolescent patients with BDs have been confirmed to have a high comorbidity rate with many other kinds of disorders. Both medication and psychological therapies have been shown to be safe and efficient methods for the treatment of BD. This review summarizes the research status related to the epidemiology, pathogenic factors, clinical manifestations, comorbidities, diagnostic and treatment scales, medications, and psychological therapies associated with BDs.

Bipolar Disorder and Comorbid Use of Illicit Substances

Substance use disorders (SUD) are highly prevalent in bipolar disorder (BD) and significantly affect clinical outcomes. Incidence and management of illicit drug use differ from alcohol use disorders, nicotine use of behavioral addictions. It is not yet clear why people with bipolar disorder are at higher risk of addictive disorders, but recent data suggest common neurobiological and genetic underpinnings and epigenetic alterations. In the absence of specific diagnostic instruments, the clinical interview is conducive for the diagnosis. Treating SUD in bipolar disorder requires a comprehensive and multidisciplinary approach. Most treatment trials focus on single drugs, such as cannabis alone or in combination with alcohol, cocaine, or amphetamines. Synopsis of data provides limited evidence that lithium and valproate are effective for the treatment of mood symptoms in cannabis users and may reduce substance use. Furthermore, the neuroprotective agent citicoline may reduce cocaine consumption in BD subjects. However, many of the available studies had an open-label design and were of modest to small sample size. The very few available psychotherapeutic trials indicate no significant differences in outcomes between BD with or without SUD. Although SUD is one of the most important comorbidities in BD with a significant influence on clinical outcome, there is still a lack both of basic research and clinical trials, allowing for evidence-based and specific best practices.

Comorbid Bipolar and Alcohol Use Disorder-A Therapeutic Challenge

Comorbidity rates in Bipolar disorder rank highest among major mental disorders, especially comorbid substance use. Besides cannabis, alcohol is the most frequent substance of abuse as it is societally accepted and can be purchased and consumed legally. Estimates for lifetime comorbidity of bipolar disorder and alcohol use disorder are substantial and in the range of 40-70%, both for Bipolar I and II disorder, and with male preponderance. Alcohol use disorder and bipolarity significantly influence each other's severity and prognosis with a more complicated course of both disorders. Modern treatment concepts acknowledge the interplay between these disorders using an integrated therapy approach where both disorders are tackled in the same setting by a multi-professional team. Motivational interviewing, cognitive behavioral and socio- therapies incorporating the family and social environment are cornerstones in psychotherapy whereas the accompanying pharmacological treatment aims to reduce craving and to optimize mood stability. Adding valproate to lithium may reduce alcohol consumption whereas studies with antipsychotics or naltrexone and acamprosate did not affect mood fluctuations or drinking patterns. In summary, there is a continuous need for more research in order to develop evidence-based approaches for integrated treatment of this frequent comorbidity.

Lithium Versus Other Mood-Stabilizing Medications in a Longitudinal Study of Youth Diagnosed With Bipolar Disorder

OBJECTIVE

Lithium is the mainstay for bipolar disorder (BD) treatment in adults, but evidence in youths is limited. We used data from the Course and Outcome of Bipolar Youth (COBY) study to assess whether lithium vs other mood-stabilizing medication (OMS) was associated with improved outcomes, including mood symptoms and suicidality.

METHOD

COBY is a naturalistic, longitudinal study of 413 youths, 7 to 17.11 years old at intake, with BD. At each visit, medication exposure, psychiatric symptoms, and psychosocial function over the preceding follow-up period were assessed using the Adolescent Longitudinal Interval Follow-Up Evaluation. Using mixed models, we determined whether participants taking lithium vs OMS (but not lithium) differed regarding mood symptoms, suicidality, psychosocial function, hospitalization, aggression, and substance use.

RESULTS

A total of 340 participants contributed 2,638 six-month follow-up periods (886 lithium, 1,752 OMS), over a mean follow-up of 10 years. During lithium (vs OMS) follow-up periods, participants were older, less likely to have lifetime anxiety, and less likely to be on antidepressants (p values<.005). After covariate adjustment, the lithium group (vs OMS) had half as many suicide attempts (p = .03), fewer depressive symptoms (p = .004), less psychosocial impairment (p = .003), and less aggression (p = .0004). Similar findings were observed in the subgroup of follow-up periods in which participants were <18 years old.

CONCLUSION

Findings are consistent with adult studies, showing that lithium is associated with decreased suicidality, less depression, and better psychosocial functioning. Given the paucity of evidence regarding lithium in children and adolescents, these findings have important clinical implications for the pharmacological management of youths with BD.

Update on the treatment of bipolar disorder in children and adolescents

As the phenomenology of pediatric bipolar disorder has become better delineated, clinicians are now able to more accurately assess and treat young people suffering from this condition. For pediatric patients with bipolar I disorder and symptoms of mania, medication monotherapy has been shown to lead to symptom amelioration. However, this treatment modality oftentimes does not lead to full symptom remission. In an attempt to address this observation, combination treatment strategies have recently been investigated. Recently, a maintenance study has shown that in youths who achieved remission on a combination of lithium and divalproate therapy, either of these agents alone was equally effective as a treatment strategy. In youths identified as being at genetic high risk for bipolarity who also had problematic affective symptomatology, treatment with divalproate was not found to be superior to placebo; however, those with the greatest degree of genetic risk for familial psychopathology remained in the trial longer than those with more modest amounts of familial psychopathology. These data suggest that intervention in youths with only one affected parent may not be a rational prevention strategy for pharmacological intervention in bipolar disorder, and that cohorts more genetically at risk may be a more appropriate group for preventative pharmacotherapy.

Substance Use Disorders in Vulnerable Children

Substance use remains a major challenge in adolescent health. The coexisting use of these substances often creates hurdles for accurate diagnosis of other comorbid psychiatric conditions. It is of critical importance that health care providers be aware of both the isolated presentation of substance use disorder and that with coexisting psychiatric illness in vulnerable children.

Effect of lithium on suicide and mortality in mood disorders: A systematic review

OBJECTIVE

To assess if lithium treatment in patients with mood disorders, for instance depression, bipolar disorders, and schizoaffective disorders, has an effect on total mortality and suicide.

DESIGN

Systematic review and meta-analysis.

MAIN OUTCOME MEASURE

Total mortality. Secondary outcome was suicide.

DATA SOURCES

PubMed and ClinicalTrials.gov. Eligible trials were randomized double-blind trials comparing lithium with placebo in patients with mood disorders who were not already on lithium before randomization in order to avoid withdrawal effects in the placebo group.

DATA EXTRACTION AND ANALYSIS

Two researchers extracted data independently. Data were analysed with Review Manager 5.3 (Peto odds ratio).

RESULTS

We found 45 eligible studies. Only four studies reported any suicides or other deaths in the lithium or placebo group. There was a significant reduction in total mortality (two versus nine), odds ratio 0.28 (95% confidence interval 0.08 to 0.93). There was no statistically significant reduction in suicides, (none versus three), odds ratio 0.13 (0.01 to 1.27).

CONCLUSION

According to our study, lithium reduces total mortality in mood disorders but not suicide. Because of small numbers and unreliable data, the findings should be interpreted with caution.

Pharmacotherapies for co-occurring substance use and bipolar disorders: A systematic review

OBJECTIVES

Substance use disorders (SUDs), including those for alcohol, stimulants, tobacco, opioids and cannabis, in patients with bipolar disorder are a major clinical and public health problem, and are present in the majority of these patients. Nonetheless, the development of effective pharmacological treatments for co-occurring SUDs in bipolar illness have not been well-developed and may be an important practical reason for the reduced effectiveness of these medications in community practice.

METHODS

We conducted a systematic review of the literature (PubMed, Medline, Google Scholar), and identified N = 29 clinical studies, which evaluated both mental health and SUD outcomes in patients with co-occurring bipolar disorders and SUDs.

RESULTS

Our findings suggest the potential of valproate sodium and lamotrigine as preferred pharmacological agents for the treatment of co-occurring psychiatric and substance use outcomes in these patients. However, many of the reviewed studies are of open-label designs and of modest sample sizes.

CONCLUSIONS

Thus, given the gaps in our knowledge, recommendations for treatment of this common and important co-morbidity are preliminary. Accordingly, the conduct of larger, randomized controlled trials for this co-morbidity is clearly needed.

Effect size of lithium, carbamazepine, and sodium valproate in child and adolescent bipolar 1 disorder during manic phase: A prospective open-label study

AIM

The aim was to evaluate the "effect size (ES)," tolerability, and acceptability of lithium, carbamazepine, and sodium valproate in the acute phase treatment of pediatric Bipolar 1 disorder patients during manic phase.

MATERIALS AND METHODS

This hospital-based, prospective, open-label study included 67 patients in manic phase of bipolar I disorder, aged 6-17 years, after informed consent by the caregivers. The patients were randomly assigned to the lithium group (n = 30), carbamazepine group (n = 20), and sodium valproate group (n = 17). They were assessed with the Schedule for Affective Disorders for School Age Children's-Present and Life time version administered to the parent and child separately, Conner's Abbreviated Rating Scale, and Cassidy Scale for Manic States (CSMS). Lithium was started in the dose of 30 mg per kg of body weight, carbamazepine in the dose of 10-20 mg/kg/day, and sodium valproate in the dose of 10-20 mg/kg body weight. Antipsychotic (chlorpromazine [CPZ] 100-500 mg per day or haloperidol up to 750 mg of CPZ equivalent) was allowed in the study. Injection haloperidol 10 mg and injection promethazine 50 mg intramuscular were allowed for initial 3-5 days to combat acute agitation. Rescue medication such as injection lorazepam 2-4 mg intramuscular was allowed throughout the study duration. The patients were rated weekly on CSMS, Bipolar Clinical Global Impression, Udvalg for kliniske Undersogelser Side Effect Rating Scale, and side effect checklist for lithium, sodium valproate, and carbamazepine, respectively. The serum level of concerned drug was obtained at weekly intervals and dose hiked, if needed to get target serum level.

RESULTS

The response rate was 90% in lithium group, 70% in carbamazepine group, and 88% in sodium valproate group on the basis of ≥33% reduction from baseline CSMS. The effects of change of CSMS over the 6 weeks across the three treatment group were found to be highly statistically significant.

CONCLUSIONS

In the acute phase treatment of pediatric bipolar 1 disorder patients during manic phase, the ES for lithium was 0.85, for carbamazepine 0.71, and for sodium valproate 0.84. These agents are well tolerated in treating bipolar disorder in children.

Pharmacotherapies for cannabis dependence

BACKGROUND

Globally, cannabis use is prevalent and widespread. There are currently no pharmacotherapies approved for treatment of cannabis use disorders.This is an update of a Cochrane Review first published in the Cochrane Library in Issue 12, 2014.

OBJECTIVES

To assess the effectiveness and safety of pharmacotherapies as compared with each other, placebo or no pharmacotherapy (supportive care) for reducing symptoms of cannabis withdrawal and promoting cessation or reduction of cannabis use.

SEARCH METHODS

We updated our searches of the following databases to March 2018: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO and Web of Science.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs involving the use of medications to treat cannabis withdrawal or to promote cessation or reduction of cannabis use, or both, in comparison with other medications, placebo or no medication (supportive care) in people diagnosed as cannabis dependent or who were likely to be dependent.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included 21 RCTs involving 1755 participants: 18 studies recruited adults (mean age 22 to 41 years); three studies targeted young people (mean age 20 years). Most (75%) participants were male. The studies were at low risk of performance, detection and selective outcome reporting bias. One study was at risk of selection bias, and three studies were at risk of attrition bias.All studies involved comparison of active medication and placebo. The medications were diverse, as were the outcomes reported, which limited the extent of analysis.Abstinence at end of treatment was no more likely with Δ⁹-tetrahydrocannabinol (THC) preparations than with placebo (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.64 to 1.52; 305 participants; 3 studies; moderate-quality evidence). For selective serotonin reuptake inhibitor (SSRI) antidepressants, mixed action antidepressants, anticonvulsants and mood stabilisers, buspirone and N-acetylcysteine, there was no difference in the likelihood of abstinence at end of treatment compared to placebo (low- to very low-quality evidence).There was qualitative evidence of reduced intensity of withdrawal symptoms with THC preparations compared to placebo. For other pharmacotherapies, this outcome was either not examined, or no significant differences was reported.Adverse effects were no more likely with THC preparations (RR 1.02, 95% CI 0.89 to 1.17; 318 participants; 3 studies) or N-acetylcysteine (RR 0.94, 95% CI 0.71 to 1.23; 418 participants; 2 studies) compared to placebo (moderate-quality evidence). For SSRI antidepressants, mixed action antidepressants, buspirone and N-acetylcysteine, there was no difference in adverse effects compared to placebo (low- to very low-quality evidence).There was no difference in the likelihood of withdrawal from treatment due to adverse effects with THC preparations, SSRIs antidepressants, mixed action antidepressants, anticonvulsants and mood stabilisers, buspirone and N-acetylcysteine compared to placebo (low- to very low-quality evidence).There was no difference in the likelihood of treatment completion with THC preparations, SSRI antidepressants, mixed action antidepressants and buspirone compared to placebo (low- to very low-quality evidence) or with N-acetylcysteine compared to placebo (RR 1.06, 95% CI 0.93 to 1.21; 418 participants; 2 studies; moderate-quality evidence). Anticonvulsants and mood stabilisers appeared to reduce the likelihood of treatment completion (RR 0.66, 95% CI 0.47 to 0.92; 141 participants; 3 studies; low-quality evidence).Available evidence on gabapentin (anticonvulsant), oxytocin (neuropeptide) and atomoxetine was insufficient for estimates of effectiveness.

AUTHORS' CONCLUSIONS

There is incomplete evidence for all of the pharmacotherapies investigated, and for many outcomes the quality of the evidence was low or very low. Findings indicate that SSRI antidepressants, mixed action antidepressants, bupropion, buspirone and atomoxetine are probably of little value in the treatment of cannabis dependence. Given the limited evidence of efficacy, THC preparations should be considered still experimental, with some positive effects on withdrawal symptoms and craving. The evidence base for the anticonvulsant gabapentin, oxytocin, and N-acetylcysteine is weak, but these medications are also worth further investigation.

Putative Mechanisms of Action and Clinical Use of Lithium in Children and Adolescents: A Critical Review

BACKGROUND

Lithium is a first-line treatment for bipolar disorder in adults, but its mechanism of action is still far from clear. Furthermore, evidences of its use in pediatric populations are sparse, not only for bipolar disorders, but also for other possible indications.

OBJECTIVES

To provide a synthesis of published data on the possible mechanisms of action of lithium, as well as on its use in pediatric samples, including pharmacokinetics, efficacy, and safety data.

METHODS

Clinical trials in pediatric samples with at least one standardized measure of efficacy/ effectiveness were included in this review. We considered: i) randomized and open label trials, ii) combination studies iii) augmentation studies iv) case series including at least 5 patients.

RESULTS

Different and non-alternative mechanisms of action can explain the clinical efficacy of lithium. Clinical studies in pediatric samples suggest that lithium is effective in managing manic symptoms/episodes of bipolar disorder, both in the acute phase and as maintenance strategy. Efficacy on depressive symptoms/phases of bipolar disorder is much less clear, while studies do not support its use in unipolar depression and severe mood dysregulation. Conversely, it may be effective on aggression in the context of conduct disorder. Other possible indications, with limited published evidence, are the acute attacks in Kleine-Levin syndrome, behavioral symptoms of X-fragile syndrome, and the management of clozapine- or chemotherapy- induced neutropenia. Generally, lithium resulted relatively safe.

CONCLUSIONS

Lithium seems an effective and well-tolerated medication in pediatric bipolar disorder and aggression, while further evidences are needed for other clinical indications.

Effects of valproate on brain volumes in pediatric bipolar disorder: A preliminary study

Sodium valproate (VPA) has well-established neuroprotective effects and is recommended as treatment in bipolar disorder patients. The neural effects of VPA in pediatric bipolar disorder (PBD) have yet to be established. This preliminary study explored the effects of VPA on brain structure in PBD. Fourteen PBD patients (10 males; mean = 13.43 ± 3.05 years old) underwent a structural MRI before and after a 6-week VPA treatment period. Bayesian linear mixed modeling explored seven brain region volumes as a function of dichotomous pre/post time. Results showed a decrease in amygdala volume over time. These findings need to be confirmed by large-scale, longitudinal studies.

Using Lithium in Children and Adolescents with Bipolar Disorder: Efficacy, Tolerability, and Practical Considerations

Lithium has been an intriguing treatment option in psychiatry for over a century. While seemingly just a simple elemental compound, it has powerful treatment effects for both depression and bipolar disorder. The evidence base for treatment of pediatric bipolar disorder is relatively small, but, in recent years, additional clinical trial data have enabled lithium to re-emerge as a valuable and, in many cases, preferred treatment. Pharmacologically, lithium is complex, with varied effects at both intracellular and extracellular levels. As a treatment for bipolar disorder in pediatrics, lithium is challenging, given its narrow therapeutic window and myriad of potential side effects. However, the efficacy of lithium continues to match that of newer pharmacologic agents, and its tolerability has been shown to be comparable with more commonly prescribed medications. Lithium is still one of few drugs that have been proven to reduce the risk of suicidality, and it may have utility in illnesses beyond affective disorders. Practically, as a primary agent or as an adjunct, lithium continues to claim a rightful place in the treatment armamentarium of child psychiatry. New dosing paradigms have improved tolerability and reduced potential side effects. Recent evidence affirms that lithium is effective for pediatric bipolar disorder in multiple phases of the illness.

Safety and efficacy of lithium in children and adolescents: A systematic review in bipolar illness

Introduction:

Many clinicians are reluctant to use traditional mood-stabilizing agents, especially lithium, in children and adolescents. This review examined the evidence for lithium’s safety and efficacy in this population.

Methods:

A systematic review was conducted on the use of lithium in children and adolescents with bipolar disorder (BD). Relevant papers published through June 30th 2018 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library.

Results:

30 articles met inclusion criteria, including 12 randomized controlled trials (RCTs). Findings from RCTs demonstrate efficacy for acute mania in up to 50% of patients, and evidence of long-term maintenance efficacy. Lithium was generally safe, at least in the short term, with most common side effects being gastrointestinal, polyuria, or headache. Only a minority of patients experienced hypothyroidism. No cases of acute kidney injury or chronic kidney disease were reported.

Conclusions:

Though the available literature is mostly short-term, there is evidence that lithium monotherapy is reasonably safe and effective in children and adolescents, specifically for acute mania and for prevention of mood episodes.

Canadian Network for Mood and Anxiety Treatments (CANMAT) and International Society for Bipolar Disorders (ISBD) 2018 guidelines for the management of patients with bipolar disorder

The Canadian Network for Mood and Anxiety Treatments (CANMAT) previously published treatment guidelines for bipolar disorder in 2005, along with international commentaries and subsequent updates in 2007, 2009, and 2013. The last two updates were published in collaboration with the International Society for Bipolar Disorders (ISBD). These 2018 CANMAT and ISBD Bipolar Treatment Guidelines represent the significant advances in the field since the last full edition was published in 2005, including updates to diagnosis and management as well as new research into pharmacological and psychological treatments. These advances have been translated into clear and easy to use recommendations for first, second, and third- line treatments, with consideration given to levels of evidence for efficacy, clinical support based on experience, and consensus ratings of safety, tolerability, and treatment-emergent switch risk. New to these guidelines, hierarchical rankings were created for first and second- line treatments recommended for acute mania, acute depression, and maintenance treatment in bipolar I disorder. Created by considering the impact of each treatment across all phases of illness, this hierarchy will further assist clinicians in making evidence-based treatment decisions. Lithium, quetiapine, divalproex, asenapine, aripiprazole, paliperidone, risperidone, and cariprazine alone or in combination are recommended as first-line treatments for acute mania. First-line options for bipolar I depression include quetiapine, lurasidone plus lithium or divalproex, lithium, lamotrigine, lurasidone, or adjunctive lamotrigine. While medications that have been shown to be effective for the acute phase should generally be continued for the maintenance phase in bipolar I disorder, there are some exceptions (such as with antidepressants); and available data suggest that lithium, quetiapine, divalproex, lamotrigine, asenapine, and aripiprazole monotherapy or combination treatments should be considered first-line for those initiating or switching treatment during the maintenance phase. In addition to addressing issues in bipolar I disorder, these guidelines also provide an overview of, and recommendations for, clinical management of bipolar II disorder, as well as advice on specific populations, such as women at various stages of the reproductive cycle, children and adolescents, and older adults. There are also discussions on the impact of specific psychiatric and medical comorbidities such as substance use, anxiety, and metabolic disorders. Finally, an overview of issues related to safety and monitoring is provided. The CANMAT and ISBD groups hope that these guidelines become a valuable tool for practitioners across the globe.

Lithium treatment in bipolar adolescents: a follow-up naturalistic study

BACKGROUND

Although lithium is currently approved for the treatment of bipolar disorders in youth, long term data, are still scant. The aim of this study was to describe the safety and efficacy of lithium in referred bipolar adolescents, who were followed up at the 4th (T1) and 8th (T2) month of treatment.

METHODS

The design was naturalistic and retrospective, based on a clinical database, including 30 patients (18 males, mean age 14.2±2.1 years).

RESULTS

Mean blood level of lithium was 0.69±0.20 mEq/L at T1 and 0.70±0.18 mEq/L at T2. Both Clinical Global Impression-Severity (CGI-S) and Children Global Assessment Scale (C-GAS) scores improved from baseline (CGI-S 5.7±0.5, C-GAS 35.1±3.7) to T1 (CGI-S 4.2±0.70, C-GAS 46.4±6.5; P<0.001), without significant differences from T1 to T2. Thyroid-stimulating hormone significantly increased from 2.16±1.8 mU/mL at baseline to 3.9±2.7 mU/mL at T2, remaining within the normal range, without changes in T3/T4 levels; two patients needed a thyroid hormone supplementation. Creatinine blood level did not change. No cardiac symptoms and electrocardiogram QTc changes occurred. White blood cell count significantly increased from 6.93±1.68 10³/mmc at baseline to 7.94±1.94 10³/mmc at T2, and serum calcium significantly increased from 9.68±0.3 mg/dL at baseline to 9.97±0.29 mg/dL at T2, both remaining within the normal range; all the other electrolyte levels were stable and normal during the follow-up. The treatment with lithium was well tolerated, probably due to the relatively low lithium blood levels. Gastrointestinal symptoms (16.7%), sedation (9.7%) and tremor (6.4%) were the most frequently reported side effects.

CONCLUSION

Lithium was effective and safe in adolescent bipolar patients followed-up for eight months.

The International Society for Bipolar Disorders Task Force report on pediatric bipolar disorder: Knowledge to date and directions for future research

OBJECTIVES

Over the past two decades, there has been tremendous growth in research regarding bipolar disorder (BD) among children and adolescents (ie, pediatric BD [PBD]). The primary purpose of this article is to distill the extant literature, dispel myths or exaggerated assertions in the field, and disseminate clinically relevant findings.

METHODS

An international group of experts completed a selective review of the literature, emphasizing areas of consensus, identifying limitations and gaps in the literature, and highlighting future directions to mitigate these gaps.

RESULTS

Substantial, and increasingly international, research has accumulated regarding the phenomenology, differential diagnosis, course, treatment, and neurobiology of PBD. Prior division around the role of irritability and of screening tools in diagnosis has largely abated. Gold-standard pharmacologic trials inform treatment of manic/mixed episodes, whereas fewer data address bipolar depression and maintenance/continuation treatment. Adjunctive psychosocial treatment provides a forum for psychoeducation and targets primarily depressive symptoms. Numerous neurocognitive and neuroimaging studies, and increasing peripheral biomarker studies, largely converge with prior findings from adults with BD.

CONCLUSIONS

As data have accumulated and controversy has dissipated, the field has moved past existential questions about PBD toward defining and pursuing pressing clinical and scientific priorities that remain. The overall body of evidence supports the position that perceptions about marked international (US vs elsewhere) and developmental (pediatric vs adult) differences have been overstated, although additional research on these topics is warranted. Traction toward improved outcomes will be supported by continued emphasis on pathophysiology and novel therapeutics.

Pharmacological Treatment of Bipolar Disorder with Comorbid Alcohol Use Disorder

Bipolar disorder (BD) spectrum and alcohol use disorders (AUDs) commonly occur together. Comorbidity between the two conditions predisposes patients to elevated risks of adverse outcomes, including hospitalization and suicide, compared with either condition alone. Despite the consistent relationship observed between BD and AUD, the underlying cause remains incompletely characterized. Few trials conducted have been able to identify promising interventions for patients with these disease states. The antipsychotic quetiapine has been evaluated most commonly as a therapeutic agent for patients with BD and AUD followed by naltrexone and acamprosate. Randomized controlled trials of quetiapine have consistently reported a lack of efficacy for the treatment of patients with BD and AUD. Trials of acamprosate have also been negative but small in size. Results of the sole randomized controlled trial of naltrexone have found large treatment effect sizes, but no statistically significant difference between treatment groups. Other agents including the antipsychotic aripiprazole, mood stabilizing agents including lamotrigine, lithium, and divalproex, and the antiepileptic agent topiramate have also been evaluated for the treatment of BD and AUD with mixed findings. The lone statistically significant treatment effect was observed in a randomized, placebo-controlled trial of divalproex added on to lithium which demonstrated a reduction in alcohol use. This review summarizes the available clinical evidence and current guideline recommendations for the treatment of comorbid BD and AUD, and provides discussion and recommendations based on the current literature.

A placebo controlled study of quetiapine-XR in bipolar depression accompanied by generalized anxiety with and without a recent history of alcohol and cannabis use

OBJECTIVE

This study aims to compare treatment response in bipolar I or II depression and generalized anxiety disorder (GAD) with and without recent alcohol and/or cannabis use disorder (ALC/CAN) to quetiapine-XR (extended release) or placebo.

METHODS

A randomized, double-blind, 8-week study of quetiapine-XR versus placebo in patients with bipolar I or II depression and GAD with or without a recent ALC/CAN was used to compare changes in Hamilton Depression Rating Scale-17, Hamilton Anxiety Rating Scale, the 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR-16), Clinical Global Impression for Bipolar Disorder-Severity (CGI-BP-S), and Timeline Follow Back within and between groups.

RESULTS

In the quetiapine-XR group, patients with a recent ALC/CAN (n = 22) had significant decreases in QIDS-SR-16 (-9.6 ± 1.6 vs. -3.7 ± 1.7) and CGI-BP-S (-1.6 ± 0.4 vs. -0.8 ± 0.03) than those without a recent ALC/CAN (n = 24). In the placebo group, both patients with a recent ALC/CAN (n = 23) and those without (n = 21) had similar reductions in these measures. The reduction of QIDS-SR-16 scores in patients with a recent ALC/CAN was also significantly different from that of their counterparts in the placebo group. Patients who received quetiapine-XR had larger decreases in the number of drinking days/week (p = 0.17) and number of cannabis joints/week (p = 0.09) compared to those who received placebo.

CONCLUSION

Quetiapine-XR was superior to placebo in reducing QIDS-SR-16 total score in patients with a recent ALC/CAN. Patients taking quetiapine-XR used less alcohol and cannabis than patients on placebo, suggesting that quetiapine-XR may be of use in patients with bipolar disorder accompanied by GAD and other comorbidities.

Substance abuse in patients with bipolar disorder: A systematic review and meta-analysis

By considering the debilitating outcome of co-occurring of bipolar disorder (BD) and substance abuse, determination of risk factors of substance use disorders (SUD: abuse or dependence of drugs and/or alcohol) is essential to identify the susceptible patients. The purpose of this study was to clarify the major determinant factors of SUD among adults with BD by reviewing the relevant literature. We systematically searched electronic databases including PubMed (MEDLINE), EMBASE, OVID, Cochrane and Scopus for human studies addressing the co-existence of bipolar disorder and SUD. All potential published papers up to September 2016 have been reviewed. The statistical analysis was performed using Comprehensive Meta-analysis version 2. Male gender (Odds ratio: 2.191 (95% CI: 1.121-4.281), P 0.022), number of manic episodes (P: 0.001) and previous history of suicidality (Odds ratio: 1.758 (95% CI: 1.156-2.674), P: 0.008) were associated to SUD in patients with BD. SUD was not related to age, subtype of BD, hospitalization and co-existence of anxiety disorders or psychotic symptoms. SUD affects many aspects of BD regarding clinical course, psychopathology and prognosis. Our study demonstrates that male gender, history of higher number of manic episodes and suicidality are associated to higher susceptibility to SUD. Thus, assignment of more intensive therapeutic interventions should be considered in patients with increased risk of drug abuse to prevent development of SUD.

Ethical considerations in preventive interventions for bipolar disorder

AIM

Early intervention and prevention of serious mental disorders such as bipolar disorder has the promise of decreasing the burden associated with these disorders. With increasing early and preventive intervention efforts among cohorts such as those with a familial risk for bipolar disorder, there is a need to examine the associated ethical concerns. The aim of this review was to examine the ethical issues underpinning the clinical research on pre-onset identification and preventive interventions for bipolar disorder.

METHODS

We undertook a PubMed search updated to November 2014 incorporating search terms such as bipolar, mania, hypomania, ethic*(truncated), early intervention, prevention, genetic and family.

RESULTS

Fifty-six articles that were identified by this method as well as other relevant articles were examined within a framework of ethical principles including beneficence, non-maleficence, respect for autonomy and justice. The primary risks associated with research and clinical interventions include stigma and labelling, especially among familial high-risk youth. Side effects from interventions are another concern. The benefits of preventive or early interventions were in the amelioration of symptoms as well as the possibility of minimizing disability, cognitive impairment and progression of the illness. Supporting the autonomy of individuals and improving access to stigma-free care may help moderate the potential challenges associated with the risks of interventions.

CONCLUSIONS

Concerns about the risks of early identification and pre-onset interventions should be balanced against the potential benefits, the individuals' right to choice and by improving availability of services that balance such dilemmas.

Management of comorbid bipolar disorder and substance use disorders

BACKGROUND

The comorbidity of substance use disorders (SUDs) in bipolar disorder is among the highest in psychiatric disorders. Evidence-based controlled psychosocial or pharmacological interventions trials, which may guide treatment decisions, have not been systematically reviewed.

OBJECTIVE

To present a narrative review of the public health and clinical significance of this condition, including diagnostic and treatment implications, and to evaluate controlled trials conducted to date.

METHODS

Controlled trials reports in the English language were identified from multiple electronic databases and hand-searching bibliographies. We searched for treatment studies of bipolar disorder and comorbid SUDs (alcohol, cocaine, stimulants, opioid, tobacco, cannabis). Search period included all reports through September of 2016. We selected only randomized psychosocial studies or double-blind, placebo-controlled pharmacotherapy trials. We also reviewed reports of the public health and clinical significance and principle of managements of this condition.

RESULTS

We identified 16 treatment studies: 3 psychotherapy, and 13 pharmacotherapy trials. The following medications were evaluated: lithium carbonate, valproate, lamotrigine, topiramate, naltrexone, acamprosate, disulfiram, quetiapine, and citicoline. SUDs have substantial impact on the recognition and management of bipolar disorder. Integrated psychosocial interventions are helpful in decreasing substance abuse. Valproate and naltrexone may decrease alcohol use and citicoline may decrease cocaine use and enhance cognition.

CONCLUSIONS

There is a very limited number of pharmacotherapy and an even smaller number of psychosocial interventions. Our review highlights the need for more research in this area and for larger, multisite studies with generalizable samples to provide more definite guidance for clinical practice.

The International College of Neuro-Psychopharmacology (CINP) Treatment Guidelines for Bipolar Disorder in Adults (CINP-BD-2017), Part 2: Review, Grading of the Evidence, and a Precise Algorithm

BACKGROUND

The current paper includes a systematic search of the literature, a detailed presentation of the results, and a grading of treatment options in terms of efficacy and tolerability/safety.

MATERIAL AND METHODS

The PRISMA method was used in the literature search with the combination of the words 'bipolar,' 'manic,' 'mania,' 'manic depression,' and 'manic depressive' with 'randomized,' and 'algorithms' with 'mania,' 'manic,' 'bipolar,' 'manic-depressive,' or 'manic depression.' Relevant web pages and review articles were also reviewed.

RESULTS

The current report is based on the analysis of 57 guideline papers and 531 published papers related to RCTs, reviews, posthoc, or meta-analysis papers to March 25, 2016. The specific treatment options for acute mania, mixed episodes, acute bipolar depression, maintenance phase, psychotic and mixed features, anxiety, and rapid cycling were evaluated with regards to efficacy. Existing treatment guidelines were also reviewed. Finally, Tables reflecting efficacy and recommendation levels were created that led to the development of a precise algorithm that still has to prove its feasibility in everyday clinical practice.

CONCLUSIONS

A systematic literature search was conducted on the pharmacological treatment of bipolar disorder to identify all relevant random controlled trials pertaining to all aspects of bipolar disorder and graded the data according to a predetermined method to develop a precise treatment algorithm for management of various phases of bipolar disorder. It is important to note that the some of the recommendations in the treatment algorithm were based on the secondary outcome data from posthoc analyses.

Treating Mental Health and Substance Use Disorders in Adolescents: What Is on the Menu?

Specific treatments targeting adolescents with substance use disorders (SUDs) have been developed over the last couple of decades. Despite these developmentally tailored treatments, long-term abstinence rates remain relatively low among adolescents receiving care. Research over the last decade has increasingly focused on adolescents with comorbid substance use and psychiatric disorders, in recognition of the barriers caused by inadequate treatment of co-occurring psychiatric disorders. Treatments targeting dually diagnosed youth are now regarded as essential to improving SUD treatment outcomes, but remain underutilized. A variety of treatment modalities such as behavioral therapy, family therapy, 12-step groups, motivational interviewing, contingency management, and combinations of these interventions have been modified for adolescents. In this article, we review the research on these treatments, as they apply to dually diagnosed youth. Furthermore, we explore the evidence for various treatments targeting comorbid SUD, specific to the presence of externalizing or internalizing disorders. The current evidence base supports the importance of integrated treatment targeting both SUD and psychiatric disorders simultaneously. High-quality treatment programs offering combinations of behavioral and family therapy, particularly with motivational interviewing and contingency management, are particularly well supported. In addition, we review various psychotropic medication treatments that have also been studied in conjunction with adolescent SUD treatment. Finally, we review research on post-treatment, supportive care that has been shown to improve long-term SUD outcomes. Recently conceptualized modular treatments, which offer personalized combinations of evidence-based treatments for specific disorders, have been proposed as a means of improving outcomes. Future research on modular programs must test the efficacy of individualized treatments when applied to combinations of psychiatric and SUDs in adolescents.

Effect of lithium on thyroid function in adolescents with mood disorder

BACKGROUND

The purpose of the study was to determine thyroid gland volume and the frequency of thyroid dysfunction by using ultrasonography and laboratory parameters (TSH, T3, and T4) in long term lithium treated adolescent patients with mood disorder.

METHODOLOGY

In a cross-sectional study, we performed ultrasonography and thyroid function test in 30 adolescent patients on long-term lithium treatment for mood disorder. Patients with adequate serum lithium levels for one year or more were taken for the study. Ultrasonography examinations of thyroid gland and thyroid function test were performed in these patients. Patients who were on other mood stabilizers were taken up as controls.

RESULT

The thyroid stimulating hormone (TSH) levels and ultrasonographically measured thyroid volume were significantly higher in patients receiving lithium in comparison to patients with other mood stabilizers. A significant positive correlation was found between total thyroid volume and TSH levels.

CONCLUSION

Adolescent mood disorder patients on long term lithium therapy have increased thyroid volume and isolated increases in serum TSH levels compared to those on other mood stabilizers.

Assessment and Treatment of Adolescent Substance Use Disorders: Alcohol Use Disorders

Alcohol drinking in childhood and adolescence is a serious public health concern. Adolescence is a vulnerable period for risk-taking tendencies. Understanding the influences of problematic alcohol use is important for evolving interventions. Alcohol use in early years foreshadows a lifetime risk for psychiatric and substance use disorders. Early screening and assessment can alter tragic sequelae. We discuss clinical aspects such as confidentiality, differential levels of care, and criteria for best fitting treatments. Given the prevalence of drinking and its impact on psychiatric and substance use disorders, the need for further study and prevention are emphasized.

[Pharmacological treatment of bipolar disorder in children and adolescents]

OBJECTIVE

To review the options for acute and maintenance pharmacological treatment of bipolar disorder in children and adolescents.

METHODS

A comprehensive literature review of randomized clinical trials and open-label studies was conducted.

RESULTS

Published data from randomized controlled trials show that antipsychotics are significantly more effective than mood stabilizers in the treatment of manic or mixed episodes. Few data are available related to the treatment of depressive episodes. No trials of selective serotonin reuptake inhibitors have been conducted. Only open trials suggest that lithium and lamotrigine may be effective, whereas quetiapine did not demonstrate efficacy relative to placebo in two studies. Studies regarding the effectiveness of antipsychotics and mood stabilizers for the comorbid disorders are also few and inconclusive. Although long-term treatment is a core aspect of the management of children and adolescents with bipolar disorder, there is a lack of consistent efficacy data. If non-controlled trials suggest that lithium, lamotrigine, quetiapine, ziprazidone, and the combination of risperidone and divalproex or lithium may be useful in some conditions, only aripiprazole has shown efficacy relative to placebo for long-term symptom reduction and relapse prevention. Safety data show that the most frequently reported adverse events in children and adolescents treated with mood stabilizers are gastrointestinal and neurological, whereas use of antipsychotics is mainly related to weight gain and sedation. Lastly, while results from studies having evaluated the impact of pharmacological treatment on neuropsychological functioning are inconsistent, some of them nevertheless suggest that treatment with mood stabilizers may be associated with specific impairments.

CONCLUSION

Despite recent developments in identifying effective pharmacological interventions, numerous critical gaps remain.
