Objective:Pharmacological options for treating bipolar disorder have increased over the past 20 years, with several second-generation antipsychotics receiving regulatory approval in the 1990s. The ...authors describe trends in use of pharmacological agents in the outpatient management of bipolar disorder.Methods:Using nationally representative data from the 1997–2016 National Ambulatory Medical Care Surveys, the authors examined trends in the use of mood stabilizers, first- and second-generation antipsychotics, and antidepressants among psychiatrist visits for which bipolar disorder was listed among the primary diagnoses. A logistic regression model was used to identify statistically significant trends, with covariates including age, gender, race/ethnicity, and primary insurance.Results:Antipsychotics were increasingly more commonly prescribed, increasing from 12.4% of outpatient visits for bipolar disorder in the 1997–2000 period to 51.4% in the 2013–2016 period (adjusted odds ratio=5.05, 95% CI=3.65–7.01). Use of mood stabilizers decreased from 62.3% of visits for bipolar disorder in the 1997–2000 period to 26.4% in the 2013–2016 period (adjusted odds ratio=0.18, 95% CI=0.13–0.27). Prescription of antidepressants occurred in 47.0% of visits for bipolar disorder in the 1997–2000 period and 57.5% in the 2013–2016 period. Prescription of an antidepressant without a mood stabilizer increased substantially, from 17.9% in the 1997–2000 period to 40.9% in the 2013–2016 period (adjusted odds ratio=2.88, 95% CI=2.06–4.03).Conclusions:Substantial changes have occurred in the treatment of bipolar disorder over the past 20 years, with second-generation antipsychotics in large measure supplanting traditional mood stabilizers. Antidepressant prescriptions persisted despite a lack of evidence for their efficacy in bipolar disorder and concerns about increasing the risk of mania. Research is needed to compare the real-world effectiveness and tolerability of newer antipsychotics with those of traditional mood stabilizers.
Many patients who are at risk for tardive dyskinesia fear that they might develop the involuntary neurological movement disorder, yet it is possible for clinicians to convey a realistic ...assessment of the benefits and risks of medications that might induce TD. Clinicians need to be aware of the importance of communicating reasonable risk in a way that will not alarm patients, using tools such as probabilities and phronesis in discussions with their patients.
Bipolar disorders are a complex group of severe and chronic disorders that includes bipolar I disorder, defined by the presence of a syndromal, manic episode, and bipolar II disorder, defined by the ...presence of a syndromal, hypomanic episode and a major depressive episode. Bipolar disorders substantially reduce psychosocial functioning and are associated with a loss of approximately 10–20 potential years of life. The mortality gap between populations with bipolar disorders and the general population is principally a result of excess deaths from cardiovascular disease and suicide. Bipolar disorder has a high heritability (approximately 70%). Bipolar disorders share genetic risk alleles with other mental and medical disorders. Bipolar I has a closer genetic association with schizophrenia relative to bipolar II, which has a closer genetic association with major depressive disorder. Although the pathogenesis of bipolar disorders is unknown, implicated processes include disturbances in neuronal-glial plasticity, monoaminergic signalling, inflammatory homoeostasis, cellular metabolic pathways, and mitochondrial function. The high prevalence of childhood maltreatment in people with bipolar disorders and the association between childhood maltreatment and a more complex presentation of bipolar disorder (eg, one including suicidality) highlight the role of adverse environmental exposures on the presentation of bipolar disorders. Although mania defines bipolar I disorder, depressive episodes and symptoms dominate the longitudinal course of, and disproportionately account for morbidity and mortality in, bipolar disorders. Lithium is the gold standard mood-stabilising agent for the treatment of people with bipolar disorders, and has antimanic, antidepressant, and anti-suicide effects. Although antipsychotics are effective in treating mania, few antipsychotics have proven to be effective in bipolar depression. Divalproex and carbamazepine are effective in the treatment of acute mania and lamotrigine is effective at treating and preventing bipolar depression. Antidepressants are widely prescribed for bipolar disorders despite a paucity of compelling evidence for their short-term or long-term efficacy. Moreover, antidepressant prescription in bipolar disorder is associated, in many cases, with mood destabilisation, especially during maintenance treatment. Unfortunately, effective pharmacological treatments for bipolar disorders are not universally available, particularly in low-income and middle-income countries. Targeting medical and psychiatric comorbidity, integrating adjunctive psychosocial treatments, and involving caregivers have been shown to improve health outcomes for people with bipolar disorders. The aim of this Seminar, which is intended mainly for primary care physicians, is to provide an overview of diagnostic, pathogenetic, and treatment considerations in bipolar disorders. Towards the foregoing aim, we review and synthesise evidence on the epidemiology, mechanisms, screening, and treatment of bipolar disorders.
A task force report presents 12 recommendations for antidepressant use in bipolar disorder rated by at least 80% of International Society for Bipolar Disorders experts as essential or important.
...ObjectiveThe risk-benefit profile of antidepressant medications in bipolar disorder is controversial. When conclusive evidence is lacking, expert consensus can guide treatment decisions. The International Society for Bipolar Disorders (ISBD) convened a task force to seek consensus recommendations on the use of antidepressants in bipolar disorders.MethodAn expert task force iteratively developed consensus through serial consensus-based revisions using the Delphi method. Initial survey items were based on systematic review of the literature. Subsequent surveys included new or reworded items and items that needed to be rerated. This process resulted in the final ISBD Task Force clinical recommendations on antidepressant use in bipolar disorder.ResultsThere is striking incongruity between the wide use of and the weak evidence base for the efficacy and safety of antidepressant drugs in bipolar disorder. Few well-designed, long-term trials of prophylactic benefits have been conducted, and there is insufficient evidence for treatment benefits with antidepressants combined with mood stabilizers. A major concern is the risk for mood switch to hypomania, mania, and mixed states. Integrating the evidence and the experience of the task force members, a consensus was reached on 12 statements on the use of antidepressants in bipolar disorder.ConclusionsBecause of limited data, the task force could not make broad statements endorsing antidepressant use but acknowledged that individual bipolar patients may benefit from antidepressants. Regarding safety, serotonin reuptake inhibitors and bupropion may have lower rates of manic switch than tricyclic and tetracyclic antidepressants and norepinephrine-serotonin reuptake inhibitors. The frequency and severity of antidepressant-associated mood elevations appear to be greater in bipolar I than bipolar II disorder. Hence, in bipolar I patients antidepressants should be prescribed only as an adjunct to mood-stabilizing medications.
The intestinal microbiome has been identified as a key modifier for a variety of health conditions. Fecal Microbiota Transplantation (FMT) has emerged as a fast, safe, and effective means by which to ...modify the intestinal microbiome and potentially treat a variety of health conditions. Despite extensive research of FMT for CDI, there is a lack of clarity informed by systematic synthesis of data regarding the safety and efficacy of FMT for other health conditions. This systematic review used PRISMA guidelines and was prospectively registered with PROSPERO (CRD42018104243). In March 2020, a search of MEDLINE, EMBASE, and PsycINFO was conducted. We identified 26 eligible studies. A meta-analysis of FMT for active Ulcerative Colitis (UC) showed that FMT significantly improved rates of clinical remission (OR = 3.634, 95% CI = 1.940 to 6.808, I

= 0%, p = .001). With respect to Irritable Bowel Syndrome, a meta-analysis showed no significant change in symptoms following FMT (p = .739). Hepatic disorders, metabolic syndrome, and antibiotic-resistant organisms were conditions with emerging data on FMT. Serious adverse events (AE) were more often reported in control group participants (n = 43) compared with FMT group participants (n = 26). There were similar rates of mild to moderate AE in both groups. Preliminary data suggest that FMT is a potentially safe, well-tolerated and efficacious treatment for certain conditions other than CDI, with evidence for active UC being the most compelling.
Adult outpatients with a nonpsychotic major depressive disorder received sustained-release bupropion, sertraline, or extended-release venlafaxine after a lack of response to or an inability to ...tolerate the selective serotonin-reuptake inhibitor (SSRI) citalopram. Approximately one in four patients had a remission of symptoms after switching to another antidepressant. All these medications provided a reasonable second-step choice for depressed outpatients who did not have a remission with or could not tolerate the SSRI.

subsequent interventions are often needed. Second-step treatments include augmenting the first agent with a second or discontinuing the first agent and beginning a second (switching). The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) Trial used an equipoise, stratified, randomized design to evaluate the relative efficacy and tolerability of various antidepressant treatments for outpatients with nonpsychotic major depressive disorder who had a lack of remission or could not tolerate the selective serotonin-reuptake inhibitor (SSRI) citalopram (Celexa, Forest Pharmaceuticals) . . .
