In the last decade new psychotropic agents have been licensed for the treatment of bipolar depression and mania. We wanted to evaluate if this led to changes in psychotropic prescriptions for bipolar-inpatients over the time-period from 2000 to 2007.On two reference-days per hospital and per year, the following data are recorded for all patients on the wards under AMSP surveillance: all drugs applied on that day with the daily dosage for psychotropic drugs, ICD-diagnosis, age, and sex. In our analysis we evaluated data from 2000 (N = 210) and 2007 (N = 383).We found a decrease of psychotropic monotherapy from 13.8% in 2000 to 4.7% in 2007. The percentage of inpatients receiving 5 or more psychotropics increased significantly from 10.95% in 2000 to 22.19% in 2007 (chi2: 11.199, df:1, p < 0.001). Furthermore we found a significant decrease of prescriptions for one or two psychotropics (38.89% to 16.38%) in bipolar-depressed-inpatients, but not in bipolar-hypo/manic-inpatients (chi2: 17.929, df:1, p < 0.001). The most frequently prescribed psychotropic in bipolar depression in 2000 was lithium-carbonate (median-dosage: 675 mg/day) and in 2007 valproic-acid (median-dosage: 1000 mg/day). In bipolar hypo-/mania the most commonly prescribed psychotropic in 2000 was again lithium-carbonate (median-dosage: 675 mg/day) and in 2007 valproic-acid (median-dosage: 1500 mg/day). The most frequently prescribed combinations were those of cbamazepine with lithium-carbonate (4.76%) in 2000 and of valproic-acid with quetiapine (8.88%) in 2007.In our bipolar sample polypharmacy increased over the years. Further studies evaluating the safety of this polypharmacy, as well as putative effects of psychotropic combination-treatment in bipolar disorder are needed.

Facilitatory Effect

One strategy to understand bipolar disorder is to study the mechanism of action of mood-stabilizing drugs, such as valproic acid and lithium. This approach has implicated a number of intracellular signalling elements, such as GSK3β (glycogen synthase kinase 3β), ERK (extracellular-signal-regulated kinase)/MAPK (mitogen-activated protein kinase) or protein kinase C. However, lamotrigine does not seem to modulate any of these targets, which is intriguing given that its profile in the clinic differs from that of valproic acid or lithium, with greater efficacy to prevent episodes of depression than mania. The primary target of lamotrigine is the voltage-gated sodium channel, but it is unclear why inhibition of these channels might confer antidepressant efficacy. In healthy volunteers, we found that lamotrigine had a facilitatory effect on the BOLD (blood-oxygen-level-dependent) response to TMS (transcranial magnetic stimulation) of the prefrontal cortex. This effect was in contrast with an inhibitory effect of lamotrigine when TMS was applied over the motor cortex. In a follow-up study, a similar prefrontal specific facilitatory effect was observed in a larger cohort of healthy subjects, whereas valproic acid inhibited motor and prefrontal cortical TMS-induced BOLD response. In vitro, we found that lamotrigine (3–10 μM) enhanced the power of gamma frequency network oscillations induced by kainic acid in the rat hippocampus, an effect that was not observed with valproic acid (100 μM). These data suggest that lamotrigine has a positive effect on corticolimbic network function that may differentiate it from other mood stabilizers. The results are also consistent with the notion of corticolimbic network dysfunction in bipolar disorder.

IntroductionPsychotropic polypharmacy is widely used in routine clinical practice although there is still a substantial deficit in established knowledge about combination and augmentation treatments. Polypharmacy is related with a higher risk of adverse drug reactions and incompliance.MethodsOn two reference days per hospital and per year, the following data are recorded for all patients on the wards under AMSP surveillance: all drugs applied on that day with the daily dosage for psychotropic drugs, ICD diagnosis, age, and sex. Data is stored at the study center in Munich. We evaluated data from 2000 (N = 5669) and 2007 (N = 8346).ResultsFrom 2000 to 2007 inpatient prescriptions including three or more drugs increased significantly from 59.4% to 69.3% (chi2: 144.913; df:1; p < 0.001). Furthermore the percentage of inpatients being prescribed three or more psychotropics increased significantly from 36.5% in 2000 to 47.97% in 2007 (chi2: 180.01; df:1; p < 0.001).Investigating further, which inpatients, diagnosed according to ICD-10, tend to be treated with more than two psychotropics, we found that this was more common in inpatients, who had an F2., F3. or F9. ICD-10 diagnosis. Especially inpatients with a bipolar disorder (F31.) showed an extremely high rate for psychotropic polypharmacy with three or more psychotropic drugs, with rates of 63,8% in 2000 and 75,2% in 2007.ConclusionPolypharmacy is still gaining ground. Our results show that psychotropic agents are commonly used in combination; therefore further studies evaluating assumable positive results of psychotropic combinations are needed.

Objective This study was conducted to examine how Canadian psychiatrists manage bipolar depression. Method A questionnaire specific to the treatment of bipolar depression was mailed to 1639 active members of the Canadian Psychiatric Association. Results Seven hundred and sixty-six completed questionnaires were returned (46.7%). Most psychiatrists indicated that a combination of psychotherapy and somatic therapy was their preferred approach. For bipolar disorder, depressed, lithium carbonate and selective serotonin reuptake inhibitors (SSRIs) were the preferred treatment strategies. For substitution, tricyclic antidepressants (TCAs) were the favoured choice. Lithium carbonate was the preferred choice for augmentation and addition. Conclusion These findings indicate that a combination of psychotherapy and somatic therapy is the preferred treatment approach for bipolar depression. Lithium carbonate and SSRIs are the favoured somatic therapies.

Background: Lithium is a light, metallic element and minerals containing it are most abundant in the Andes. John Cade introduced lithium carbonate for the treatment of mania in 1949, opening the era of modern clinical psychopharmacology. Lithium remains the most extensively studied mood-stabilizing agent. It has had a revolutionary impact in supporting bipolar manic-depressive disorder as a discrete diagnosis, and on psychiatric therapeutics. Methods: We survey the development of lithium treatment in psychiatry, including findings concerning effects on suicide. Results: Lithium is the most extensively studied treatment for bipolar disorder and the prototypical mood-stabilizing agent, despite emergence of anticonvulsants and modern antipsychotics. In addition to limiting recurrences of mania, and some reduction of recurrences of bipolar depression, lithium has demonstrated protective effects against suicide. All treatments for bipolar disorder have notable limitations, including sometimes serious adverse effects, incomplete prevention of recurrences of mania and limited prevention of depression, which accounts for three-quarters of the approximately 50% time-ill in long-term follow-up with standard treatments. Lithium can be toxic in untreated overdoses; safe dosing requires monitoring of serum concentrations. Lithium also may have mild teratogenic effects, but far less than those of anticonvulsants used for bipolar disorder. Conclusions: Lithium opened the era of modern psychopharmacology and continues as the best-established mood-stabilizing treatment for bipolar disorder as well as having strong evidence of suicide-preventing effects.

The Brain

Although lithium has been used therapeutically to treat patients with bipolar disorder for over 50 years, its mechanism of action, as well as that of other drugs used to treat bipolar disorder, is not agreed upon. In the present paper, I review studies in unanaesthetized rats using a neuropharmacological approach, combined with kinetic, biochemical and molecular biology techniques, demonstrating that chronic administration of three commonly used mood stabilizers (lithium, valproic acid and carbamazepine), at therapeutically relevant doses, selectively target the brain arachidonic acid cascade. Upon chronic administration, lithium and carbamazepine decrease the binding activity of activator protein-2 and, in turn, the transcription, translation and activity of its arachidonic acid-selective calcium-dependent phospholipase A2 gene product, whereas chronic valproic acid non-competitively inhibits long-chain acyl-CoA synthetase. The net overlapping effects of the three mood stabilizers are decreased turnover of arachidonic acid, but not of docosahexaenoic acid, in rat brain phospholipids, as well as decreased brain cyclo-oxygenase-2 and prostaglandin E2. As an extension of this theory, drugs that are thought to induce switching to mania, especially when administered during bipolar depression (fluoxetine and imipramine), up-regulate enzymes of the arachidonic acid cascade and turnover of arachidonic acid in rat brain phospholipids. Future basic and clinical studies on the arachidonic acid hypothesis of bipolar disorder are warranted.

Capital Value

This article provides an estimate of the human capital value of migration to Reading in the period 1851-1871 to the town's economy. This is determined by estimating total net migration to the town across this period by age and sex and assigning all migrants a value for expected lifetime economic output less expected lifetime consumption costs. The final figures are contextualised by comparison with the value of social overhead capital used to fund significant local infrastructure projects in the same time period and show that, from a human capital perspective, the value of migration to Reading was very significant. This article thus addresses significant historiographical gaps in the study of Victorian labour migration to southern provincial towns and provides an original perspective to studies of the economic value of migration and its role in the growth of such communities.

Background: Lamotrigine is a phenyltriazine medication that has been approved by the United States Food and Drug Administration as monotherapy and as an adjunctive agent for the treatment of seizure disorder. It was later approved by the FDA for the treatment of bipolar disorder. Lamotrigine is generally well tolerated by patients, but some serious symptoms can occur during treatment. These severe side effects include rashes and multi-organ failure. Lamotrigine has also been associated with the development of mental status changes, frequently when used concurrently with other medications that may impact the metabolism of lamotrigine. Objective: To present the case of a 65-year-old man being treated with lamotrigine and valproic acid who developed mental status changes after the addition of sertraline to his medication regimen, and to compare this case to existing cases reported in the literature. Discussion: Our case adds to the existing literature by demonstrating that patients may experience adverse medication effects despite lamotrigine levels that are normally considered to be in the therapeutic range, highlighting the importance of clinical correlation when obtaining medication levels. Conclusion: Clinicians should use caution interpreting lamotrigine levels when working up delirium, as normal levels may not rule out the development of lamotrigine toxicity.

Abstract Background Symptoms of anxiety co-occur in a variety of disorders including in depressive episodes of bipolar disorder and in patients with thyrotoxicosis. Treatment of refractory bipolar disorder with supraphysiologic doses of levothyroxine (L-T4) has been shown to improve the phenotypic expression of the disorder and is associated with an increase of circulating thyroid hormones. However, it might be associated with somatic and mental adverse effects. Here we report the investigation of the influence of treatment with supraphysiologic doses of L-T4 on symptoms of anxiety in patients with refractory bipolar depression. Methods Post-hoc analysis from a 6-week, multi-center, randomized, double-blind, placebo-controlled study of the effects of supraphysiologic L-T4 treatment on anxiety symptoms in bipolar depression. Anxiety symptoms were measured weekly with the Hamilton anxiety/somatization factor (HASF) score of the Hamilton Depression Rating Scale (HAMD) and the State- and Trait Anxiety Inventory (STAI). Results Treatment of both groups was associated with a significant reduction in anxiety symptoms (p < 0.001) with no statistical difference between groups (LT-4: from 5.9 (SD = 2.0) at baseline to 3.7 (SD = 2.4) at study end; placebo: from 6.1 (SD = 2.4) at baseline to 4.4 (SD = 2.8) at study end; p = 0.717). Severity of anxiety at baseline did not show a statistically significant correlation to the antidepressive effect of treatment with supraphysiologic doses of L-T4 (p = 0.811). Gender did not show an influence on the reduction of anxiety symptoms (females: from 5.6 (SD = 1.7) at baseline to 3.5 (SD = 2.4) at study end; males: from 6.1 (SD = 2.3) at baseline to 4.0 (SD = 2.4) at study end; p = 0.877). Conclusions This study failed to detect a difference in change of anxiety between bipolar depressed patients treated with supraphysiologic doses of L-T4 or placebo. Comorbid anxiety symptoms should not be considered a limitation for the administration of supraphysiologic doses of L-T4 refractory bipolar depressed patients.

Long Term Outcome

Objective: The treatment of bipolar disorder is challenging because of its clinical complexity and availability of multiple treatment options, none of which are ideal mood stabilizers. This survey studies prescription practices of psychiatrists in India and their adherence to guidelines. Method: In total, 500 psychiatrists randomly selected from the Indian Psychiatric Society membership directory were administered a face-to-face 22-item questionnaire pertaining to the management of bipolar disorder. Results: For acute mania, most practitioners preferred a combination of a mood stabilizer and an atypical antipsychotic to monotherapy. For acute depression, there was a preference for a combination of an antidepressant and a mood stabilizer over other alternatives. Electroconvulsive therapy was preferred in the treatment of severe episodes and to hasten the process of recovery. Approximately, 50% of psychiatrists prescribe maintenance treatment after the first bipolar episode, but maintenance therapy was rarely offered lifelong. While the majority (85%) of psychiatrists acknowledged referring to various clinical guidelines, their ultimate choice of treatment was also significantly determined by personal experience and reference to textbooks. Limitations: The study did not study actual prescriptions. Hence, the responses to queries in the survey are indirect measures from which we have tried to understand the actual practices, and of course, these are susceptible to self-report and social-desirability biases. This was a cross-sectional study; therefore, temporal changes in responses could not be considered. Conclusion: Overall, Indian psychiatrists seemed to broadly adhere to recommendations of clinical practice guidelines, but with some notable exceptions. The preference for antidepressants in treating depression is contrary to general restraint recommended by most guidelines. Therefore, the efficacy of antidepressants in treating bipolar depression in the context of Indian psychiatrists’ practice needs to be studied systematically. Not initiating maintenance treatment early in the course of illness may have serious implications on the long-term outcome of bipolar disorder.
