Attention-deficit/hyperactivity disorder in pregnancy and the postpartum period.

Attention-deficit/hyperactivity disorder is a childhood-onset neurodevelopmental disorder that frequently persists into adulthood with 3% of adult women having a diagnosis of attention-deficit/hyperactivity disorder. Many women are diagnosed and treated during their reproductive years, which leads to management implications during pregnancy and the postpartum period. We know from clinical practice that attention-deficit/hyperactivity disorder symptoms frequently become challenging to manage during the perinatal period and require additional support and attention. There is often uncertainty among healthcare providers about the management of attention-deficit/hyperactivity disorder in the perinatal period, particularly the safety of pharmacotherapy for the developing fetus. This guideline is focused on best practices in managing attention-deficit/hyperactivity disorder in the perinatal period. We recommend (1) mitigating the risks associated with attention-deficit/hyperactivity disorder that worsen during the perinatal period via individualized treatment planning; (2) providing psychoeducation, self-management strategies or coaching, and psychotherapies; and, for those with moderate or severe attention-deficit/hyperactivity disorder, (3) considering pharmacotherapy for attention-deficit/hyperactivity disorder, which largely has reassuring safety data. Specifically, providers should work collaboratively with patients and their support networks to balance the risks of perinatal attention-deficit/hyperactivity disorder medication with the risks of inadequately treated attention-deficit/hyperactivity disorder during pregnancy. The risks and impacts of attention-deficit/hyperactivity disorder in pregnancy can be successfully managed through preconception counselling and appropriate perinatal planning, management, and support.

Antidepressants in Type II Versus Type I Bipolar Depression: A Randomized Discontinuation Trial.

BACKGROUND: We sought to test the hypothesis that antidepressants (ADs) may show preferential efficacy and safety among patients with type II bipolar disorder (BD, BD-II) more than patients with type I BD (BD-I). METHODS: Patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, BD-I (n = 21) and BD-II (n = 49) in acute major depressive episodes were treated with ADs plus mood stabilizers to euthymia sustained for 2 months and then randomized openly to continue or discontinue ADs for up to 3 years. Outcomes were episode recurrences and changes in standardized symptom ratings. RESULTS: In follow-up averaging 1.64 years, both subgroups showed improvement in depressive episode frequency with AD continuation, but contrary to the hypothesis, more improvement was seen in BD-I than in BD-II (for type II, mean [standard deviation] decrease in depressive episodes per year, 0.21 [0.26]; for type I, mean (SD) decrease, 0.35 [0.15]). Subjects with BD-II who continued on ADs had slightly more depressive, but fewer manic/hypomanic, episodes than subjects with BD-I. No notable differences were seen in either group in time to a recurrence of mood episodes or total time-in-remission. CONCLUSIONS: The findings do not confirm the hypothesis that long-term AD treatment in patients with BP-II has better outcomes than in patients with BD-I, except somewhat lower risk of manic/hypomanic episodes.

A comparison of psychiatry and internal medicine: a bibliometric study.

OBJECTIVE: Psychiatric education needs to expose students to a broad range of topics. One resource for psychiatric education, both during initial training and in later continuing medical education, is the scientific literature, as published in psychiatric journals. The authors assessed current research trends in psychiatric journals, as compared with internal-medicine counterparts and examined their relevance to psychiatric education. METHODS: The authors classified abstracts and original articles as biological or non-biological, based on methodology, from 2008 in Archives of General Psychiatry and The American Journal of Psychiatry, as compared with The Archives of Internal Medicine and Annals of Internal Medicine. RESULTS: Biological and non-biological studies were similarly frequent in psychiatric journals (48.2% and 51.8%, respectively). Internal-medicine journals had a non-biological and epidemiological predominance (22.2% biological, 77.8% non-biological: epidemiological, 59.9%; reviews, 21.4%; clinical, 13.2%; other, 5.4%). CONCLUSION: Psychiatric journals publish more biological studies than internal-medicine journals. This tendency may influence psychiatric education and practice in a biological direction, with less attention to psychosocial or clinical approaches to psychiatry.

Long-term worsening of bipolar disorder related with frequency of antidepressant exposure.

BACKGROUND: The aim of this study of 53 persons with bipolar disorder (BD) was to evaluate the relationship between history of exposure to antidepressants (AD) and mood stabilizers (MS) and the percentage of time spent ill. METHODS: BD outpatients with more than 12 months of prospective follow-up were included. Outcome was documented using a life charting technique. Current and previous exposure to AD and MS were assessed using a scale that provides a quantitative measure of exposure to psychotropic medications. Regression models were used to correct for possible confounders. RESULTS: Previous treatment with AD was an independent predictor of polarity changes (P < .001) and mixed symptoms (P = .01). In contrast, "years of exposure to MS" was an independent predictor of time spent asymptomatic (P = .019). The ratio between exposure to AD vs MS was associated with less weeks asymptomatic (P = .03), more mixed symptomatology (P = .019), and more polarity changes (P = .001). CONCLUSIONS: Antidepressant exposure was a major predictor of mood instability in the long-term outcome of BD. The ratio used of previous exposure to AD vs MS was associated with poor outcomes, suggesting that the harmful effect of AD may be additive and related to how much they are used.

Treatment-Resistant Depression Revisited: A Glimmer of Hope.

Major Depressive Disorder (MDD) is a highly prevalent psychiatric disorder worldwide. It causes individual suffering, loss of productivity, increased health care costs and high suicide risk. Current pharmacologic interventions fail to produce at least partial response to approximately one third of these patients, and remission is obtained in approximately 30% of patients. This is known as Treatment-Resistant Depression (TRD). The burden of TRD exponentially increases the longer it persists, with a higher risk of impaired functional and social functioning, vast losses in quality of life and significant risk of somatic morbidity and suicidality. Different approaches have been suggested and utilized, but the results have not been encouraging. In this review article, we present new approaches to identify and correct potential causes of TRD, thereby reducing its prevalence and with it the overall burden of this disease entity. We will address potential contributory factors to TRD, most of which can be investigated in many laboratories as routine tests. We discuss endocrinological aberrations, notably, hypothalamic-pituitary-adrenal (HPA) axis dysregulation and thyroid and gonadal dysfunction. We address the role of Vitamin D in contributing to depression. Pharmacogenomic testing is being increasingly used to determine Single Nucleotide Polymorphisms in Cytochrome P450, Serotonin Transporter, COMT, folic acid conversion (MTHFR). As the role of immune system dysregulation is being recognized as potentially a major contributory factor to TRD, the measurement of C-reactive protein (CRP) and select immune biomarkers, where testing is available, can guide combination treatments with anti-inflammatory agents (e.g., selective COX-2 inhibitors) reversing treatment resistance. We focus on established and emerging test procedures, potential biomarkers and non-biologic assessments and interventions to apply personalized medicine to effectively manage treatment resistance in general and TRD specifically.

Citalopram for Acute and Preventive Efficacy in Bipolar Depression (CAPE-BD): A Randomized, Double-Blind, Placebo-Controlled Trial.

OBJECTIVE: To assess the efficacy and safety of citalopram in the acute and maintenance phases of bipolar depression in a randomized, double-blind, placebo-controlled trial. METHODS: Between 2007 and 2014, 119 subjects with acute major depressive episodes diagnosed with DSM-IV bipolar disorder, type I or type II, were randomized blindly to citalopram or placebo, added to standard mood stabilizers. They were followed for 6 weeks for acute efficacy (primary outcome) and up to 1 year for maintenance efficacy (secondary outcome) using scores on the Montgomery-Asberg Depression Rating Scale (MADRS) and the Mania Rating Scale of the Schedule for Affective Disorders and Schizophrenia (MRS-SADS). The study was powered for a clinically meaningful effect size. RESULTS: Mean ± SD MADRS scores changed from a baseline value of 27.4 ± 9.1 to 13.1 ± 8.4 at the end of the acute phase for citalopram versus a change from 27.4 ± 7.3 to 15.2 ± 9.9 for placebo, a clinically and statistically nonsignificant difference. Maintenance efficacy also was not better with citalopram than with placebo. Acute manic/hypomanic episodes were similar in both groups, and subjects with type II illness did not have better outcomes than subjects with type I illness. In maintenance treatment, MRS-SADS scores were greater overall, especially in subjects with a rapid-cycling illness course, with citalopram versus placebo. CONCLUSIONS: Citalopram, added to standard mood stabilizers, did not have clinically meaningful benefit versus placebo for either acute or maintenance treatment of bipolar depression. Acute mania did not worsen with citalopram, but maintenance treatment led to worsened manic symptoms, especially in subjects with a rapid-cycling course. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00562861.

Antidepressants worsen rapid-cycling course in bipolar depression: A STEP-BD randomized clinical trial.

BACKGROUND: The use of antidepressants in rapid-cycling bipolar disorder has been controversial. We report the first randomized clinical trial with modern antidepressants on this topic. METHODS: As part of the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) study, we analyzed, as an a priori secondary outcome, rapid cycling as a predictor of response in 68 patients randomized to continue vs. discontinue antidepressant treatment, after initial response for an acute major depressive episode. Outcomes assessed were percent time well and total number of episodes. All patients received standard mood stabilizers. RESULTS: In those continued on antidepressants (AD), rapid cycling (RC) subjects experienced 268% (3.14/1.17) more total mood episodes/year, and 293% (1.29/0.44) more depressive episodes/year, compared with non-rapid cycling (NRC) subjects (mean difference in depressive episodes per year RC vs. NRC was 0.85 ± 0.37 (SE), df = 28, p = 0.03). In the AD continuation group, RC patients also had 28.8% less time in remission than NRC patients (95% confidence intervals (9.9%, 46.5%), p = 0.004). No such differences between RC and NRC subjects were seen in the AD discontinuation group (Table 1). Analyses within the rapid-cycling subgroup alone were consistent with the above comparisons between RC and NRC subjects, stratified by maintenance antidepressant treatment, though limited by sample size. CONCLUSIONS: In an a priori analysis, despite preselection for good antidepressant response and concurrent mood stabilizer treatment, antidepressant continuation in rapid-cycling was associated with worsened maintenance outcomes, especially for depressive morbidity, vs. antidepressant discontinuation.

Detecting mood disorder in resource-limited primary care settings: comparison of a self-administered screening tool to general practitioner assessment.

OBJECTIVES: Although efficacious treatments for mood disorders are available in primary care, under-diagnosis is associated with under-treatment and poorer outcomes. This study compares the accuracy of self-administered screening tests with routine general practitioner (GP) assessment for detection of current mood disorder. METHODS: 197 consecutive patients attending primary care centres in Santiago, Chile enrolled in this cross-sectional study, filling out the Patients Health Questionnaire-9 (PHQ-9) for depression and the Mood Disorder Questionnaire (MDQ) for bipolar disorder, after routine GP assessment. Diagnostic accuracy of these self-administered tools was compared with GP assessment, with gold standard diagnosis established by a structured diagnostic interview with trained clinicians (SCID-I). RESULTS: The sample was 75% female, with a mean age of 48.5 (SD 16.8); 37% had a current mood disorder (positive SCID-I result for depression or bipolar disorder). Sensitivity of the screening instruments (SI) was substantially higher than GP assessment (SI: 0.8, [95% CI 0.71, 0.81], versus GP: 0.2, [95% CI 0.12, 0.25]: p-value < 0.0001), without sacrifice in specificity (SI: 0.9, [95% CI 0.86, 0.96], versus GP: 0.9, [95% CI 0.88, 0.97]: p-value = 0.7). This led to improvement in both positive predictive value (SI: 0.8, [95% CI 0.82, 0.90], versus GP: 0.6, [95% CI 0.50, 0.64]: p-value < 0.001) and negative predictive value (SI: 0.9, [95% CI 0.78, 0.91] versus GP: 0.7, [95% CI 0.56, 0.72]: p-value < 0.01). CONCLUSION: Self-administered screening tools are more accurate than GP assessment in detecting current mood disorder in low-income primary care. Such screening tests may improve detection of current mood disorder if implemented in primary care settings.

Bipolar disorder.

Bipolar disorder is a serious disorder of mood that is associated with considerable psychosocial and economic morbidity. Even though it is more common than previously thought, it has until relatively recently been somewhat neglected in terms of research when compared to disorders such as schizophrenia and major depression. Recent advances in the fields of nosology, epidemiology, and molecular genetics in particular have begun to unravel some of the complexity of this disorder and the next few years are likely to witness substantial changes to the ways in which the broad spectrum of bipolar disorders is diagnosed and managed.

A 6 week randomized double-blind placebo-controlled trial of ziprasidone for the acute depressive mixed state.

OBJECTIVE: To examine the efficacy of ziprasidone vs. placebo for the depressive mixed state in patients with bipolar disorder type II or major depressive disorder (MDD). METHODS: 73 patients were randomized in a double-blinded, placebo-controlled study to ziprasidone (40-160 mg/d) or placebo for 6 weeks. They met DSM-IV criteria for a major depressive episode (MDE), while also meeting 2 or 3 (but not more nor less) DSM-IV manic criteria. They did not meet DSM-IV criteria for a mixed or manic episode. Baseline psychotropic drugs were continued unchanged. The primary endpoint measured was Montgomery-Åsberg Depression Rating Scale (MADRS) scores over time. The mean dose of ziprasidone was 129.7±45.3 mg/day and 126.1±47.1 mg/day for placebo. RESULTS: The primary outcome analysis indicated efficacy of ziprasidone versus placebo (p = 0.0038). Efficacy was more pronounced in type II bipolar disorder than in MDD (p = 0.036). Overall ziprasidone was well tolerated, without notable worsening of weight or extrapyramidal symptoms. CONCLUSIONS: There was a statistically significant benefit with ziprasidone versus placebo in this first RCT of any medication for the provisional diagnostic concept of the depressive mixed state. TRIAL REGISTRATION: Clinicaltrials.gov NCT00490542.

Maintenance treatment study designs in bipolar disorder: do they demonstrate that atypical neuroleptics (antipsychotics) are mood stabilizers?

In this conceptual review we argue that by certifying some of the atypical neuroleptics (or, if one prefers, antipsychotics) as indicated for the 'maintenance' treatment of bipolar disorder, the US FDA has created confusion in the field. These maintenance indications are based on studies using a 'relapse prevention' design, a design that does not address whether the agents tested can prevent new episodes of illness, i.e. recurrence prevention or true prophylaxis. We found that the relapse prevention design fails to prove that these agents are mood stabilizers because patients are pre-selected to respond to the study drug for an acute mood episode (mania) and when they relapse, they do so into an episode of the same polarity (i.e. mania). We believe that this represents withdrawal into the same mood episode that patients experienced before the maintenance study began, rather than prevention of a new mood episode, as research into the natural history of bipolar disorder indicates that such new episodes typically are of the opposite polarity. Thus, the inability of neuroleptics to prevent depression in such maintenance studies reflects the general inability to prevent any new mood episode recurrence (which we believe should be defined as 6 months or longer after the index episode). If one defines a mood stabilizer, as we do, as a drug that prevents new episodes of mania and depression in monotherapy, then these studies do not show that atypical neuroleptics are mood stabilizers. Future maintenance research studies in bipolar disorder should use the prophylaxis design (i.e. without pre-selection of drug responders), rather than the relapse prevention design.

Sensitivity and specificity of the mood disorder questionnaire and the bipolar spectrum diagnostic scale in Argentinean patients with mood disorders.

OBJECTIVE: To assess the sensitivity and specificity of two self-report instruments for detection of bipolarity in a sample of Argentinean patients. METHOD: Spanish versions of the MDQ and the BSDS were administered over four months at 11 sites in Argentina. Diagnoses were made using DSM-IV criteria and the MINI. The study sample consisted of patients diagnosed with Bipolar Disorder (BD) Types I, II, or NOS. BDNOS diagnoses were made using extended guidelines for bipolar spectrum symptoms. Unipolar patients were used as a control group. Of 493 patients screened, 354 completed evaluation by MDQ and MINI, and 363 by BSDS and MINI. RESULTS: Specificity of MDQ was 0.97 and BSDS was 0.81. MDQ sensitivity was 0.70 for bipolar type I (BD-I), 0.52 for bipolar II (BD-II) and 0.31 for bipolar not otherwise specified (BDNOS). BSDS sensitivities were 0.75, 0.70 and 0.51 respectively. LIMITATIONS: This study was performed in specialized outpatient settings and thus its results are not necessarily representative for other clinical settings. There was not a systematic evaluation of comorbid psychiatric disease or test-retest reliability. CONCLUSION: The local versions of the MDQ and the BSDS showed a sensitivity and specificity comparable to previous research. Our results indicate that in this sample, MDQ was more specific for BD and BSDS was more sensitive to detect BD-II and NOS. Since BD-I is more readily recognized than bipolar spectrum disorders, enhanced sensitivity of BSDS for soft bipolarity may be an advantage.
