    ABSTRACT: The 12-month prevalence of depression in Europe is approximately 7%; depression becomes chronic in 15-25% of sufferers. One-third to one-half do not respond to an initial trial of drug therapy lasting several weeks. Selective literature review, including consideration of the German National Disease Management Guideline Unipolar Depression. At the end of an initial trial of treatment with an antidepressant drug, usually lasting four weeks, its efficacy should be evaluated systematically. In case of non-response, the following options have been found useful: measurement of the serum drug level, dose escalation (but not for selective serotonin reuptake inhibitors [SSRIs]), lithium augmentation, the addition of a second-generation antipsychotic (atypical neuroleptic), and any one of several defined combinations of antidepressants. There is no empirical evidence for switching to another antidepressant. Electroconvulsive therapy is the most effective treatment for refractory depression. Cognitive behavioral therapy, interpersonal psychotherapy, psychoanalysis and psychodynamic psychotherapy have also been found useful. The cognitive behavioral analysis system of psychotherapy (CBASP) was developed specifically for the treatment of chronic depression. The structured application of treatments of documented efficacy, in a stepwise treatment algorithm that gives equal weight to drugs and psychotherapy, is the best way to prevent or overcome treatment resistance and chronification.

    ABSTRACT: Lithium and with restrictions, carbamazepine, valproic acid, lamotrigine, olanzapine, aripiprazole and quetiapine, are approved in Germany for maintenance treatment of bipolar disorder. Lithium is the only drug that (I) proved to be effective for the prevention of depressive as well as manic episodes in state-of-the-art studies without an enriched design and that (II) is approved for the maintenance treatment of bipolar disorders without restrictions. It (III) is also the only drug which is recommended for maintenance treatment by the current German S3 guidelines on bipolar disorders with the highest degree of recommendation (A) and (IV) is the only drug with a well proven suicide preventive effect. Hence, lithium is the mood stabilizer of first choice. No patient should be deprived of lithium without a specific reason. Side effects and risks are manageable if both the physician and the patient are well informed. Detailed and practical information on a safe use of lithium can be found in the S3 guidelines on bipolar disorders. For patients who do not respond sufficiently to lithium, have contraindications or non-tolerable side effects, other mood stabilizers should be used. Restrictions in their respective approval as well as specific side effects and risks have to be taken into account. Because maintenance treatment is a long-term treatment, particular concern should be paid to drugs with the potential risk of a metabolic syndrome, particularly atypical antipsychotics.

    ABSTRACT: Recent high-quality studies have confirmed the central role of lithium in the treatment of bipolar disorder and have established lithium as the drug of first choice for long-term prophylaxis in this condition. However, several indications for its use in unipolar major depression are also based on sound evidence. This includes lithium augmentation as a main strategy for depressed patients not responding to an antidepressant, lithium prophylaxis for recurrent unipolar depression as an alternative to prophylaxis with an antidepressant, and lithium's unique anti-suicidal properties. Lithium monotherapy, on the other hand, is not established for acute treatment of depression. Lithium therapy should be a core competency of every psychiatrist, enabling the safe use of lithium, to the benefit of our patients.

    ABSTRACT: Bipolar depression and its clinical presentation is a frequent but complex psychiatric disease. Despite the high prevalence and the clinical and economic relevance of bipolar depression, few treatments are proven to be highly and consistently effective. In practice, the treatment of bipolar depression typically includes complex treatment decision-making. The best evidence for a pharmacological treatment exists for quetiapine. Alternatives with limitations are lamotrigine (also in the combination with lithium), carbamazepine and olanzapine. The effectiveness and recommendation of antidepressants in the treatment of bipolar depression remains controversial. Initially, depressive episodes should been treated with one of the named substances with antidepressant properties. In non-responders, a combination of lithium and lamotrigine, or antidepressants in combination with either lithium, an antiepileptic drug or atypical antipsychotics, may be necessary. If a depressive episode occurs under ongoing mood-stabilizing treatment, combination treatments of different substances, even with antidepressants, can be necessary. In the case of treatment-resistant depressive episodes, complex treatment strategies (combination therapies, MAO inhibitors) should be considered. This review describes the treatment recommendations of different guidelines for bipolar depression and emphasizes their differences. Furthermore, alternative pharmacological treatment strategies and complex treatment situations are discussed.

    ABSTRACT: Treatment of bipolar depression requires complex treatment decisions in daily routine care. The best evidence for pharmacological treatment is given for quetiapine and with limitations also in off-label use for lamotrigine, especially in combination with lithium, carbamazepine and olanzapine. Effectiveness and recommendation of antidepressants in treatment of bipolar depression remain controversial because of insufficient data. Initially, in depressive episodes a phase prophylactic treatment should be initiated or (if already existing) optimized and more severe episodes should be treated with the substances described before. In case of non-response, the combination of lithium and lamotrigine or antidepressants in combination with lithium, antiepileptics or atypical antipsychotics may be necessary. If depressive episodes occur in the course of pharmacological treatment with prophylactic agents, combination therapies of different substances, even with antidepressants, are necessary. In case of treatment-resistant depressive episodes, complex treatment strategies (e.g. combination therapies and MAO inhibitors) should be considered.

    ABSTRACT: Fragestellung: Welche von drei Varianten, mit denen ein Psychiater sich vorstellt, wird von Patienten bevorzugt?Hintergrund: Die Arzt-Patienten-Beziehung ist gerade in der psychiatrischen Behandlung von nicht zu überschätzender Bedeutung. Der erste Eindruck von einem Arzt, den er bei der Begrüßung erzeugt, kann diese Beziehung in entscheidender und lang anhaltender Weise prägen. Es gibt aber keine systematische Erkenntnis, wie diese Begrüßung am günstigsten geschehen soll.Patienten und Methodik: Von zwölf Psychiatern, die den beurteilenden Patienten unbekannt waren und sie auch im Verlauf nicht behandelten, wurden je drei verschiedene Varianten sich vorzustellen per Video aufgenommen. A: eine kurze Selbstvorstellung mit Name, Beruf und Zusammenfassung des Anlasses des Aufeinandertreffens (in allen Varianten wurde davon ausgegangen, dass der Patient dem englischen System entsprechend vom Allgemeinarzt zum Psychiater überwiesen worden war); B: die gleichen Informationen wie bei A zuzügli ...

    ABSTRACT: In recent years, lithium has proved an effective augmentation strategy of antidepressants in both acute and treatment-resistant depression. Neuroprotective and procognitive effects of lithium have been evidenced. Brain-derived neurotrophic factor (BDNF) has been shown to play a key role in the pathophysiology of several neurological and psychiatric disorders. The BDNF hypothesis of depression postulates that a loss of BDNF is directly involved in the pathophysiology of depression, and its restoration may underlie the therapeutic efficacy of antidepressant treatments. Brain-derived neurotrophic factor serum concentrations were measured in a total of 83 acutely depressed patients before and after 4 weeks of lithium augmentation. A significant BDNF increase has been found during treatment (F2,81 = 5.04, P < 0.05). Brain-derived neurotrophic factor concentrations at baseline correlated negatively with relative Hamilton Depression Scale change after treatment with lithium (n = 83; r = -0.23; P < 0.05). This is the first study showing that lithium augmentation of an antidepressant strategy can increase BDNF serum concentrations. Our study replicates previous findings showing that serum BDNF levels in patients with depressive episodes increase during effective antidepressant treatment. Further studies are needed to separate specific effects of different antidepressants on BDNF concentration and address potential BDNF downstream mechanisms.

    ABSTRACT: The purpose of this study was to investigate the effectiveness and stability of long-term lithium treatment in a prospective, international, multicenter cohort of bipolar patients in a naturalistic setting. Patients were selected according to DSM IV criteria for bipolar disorder and required long-term treatment. They were prospectively followed and documented in five centers belonging to the International Group for the Study of Lithium-Treated Patients. This was a prospective cohort study without a comparison group. Lithium treatment was administered in a naturalistic and specialized outpatient setting. All patients underwent a comprehensive psychiatric examination, which included the use of standard rating scales, as well as an evaluation of clinical course based on the morbidity index (MI). Wald tests were used to assess the significance of fixed effects and covariates when analyzing the relationship between depressive, manic, and total morbidity index and several characteristics of illness course. A total of 346 patients with bipolar disorder I or II were followed for a mean period of 10.0 years (standard deviation (SD) 6.2, range 1 to 20). The morbidity index remained stable over time: the mean MI was 0.125 (SD 0.299) in year 1 and 0.110 (SD 0.267) in year 20. The MI was not associated with the duration of lithium treatment, the number or frequency of episodes prior to treatment, or latency from the onset of bipolar disorder to the start of lithium treatment. The drop-out rate was high over the study period. Our findings suggest that long-term response to lithium maintenance treatment remains stable over time.

    ABSTRACT: Bipolare Störungen sind schwerwiegende psychiatrische Erkrankungen mit einer Lebenszeitprävalenz von etwa 3% [1], oft rezidivierendem Verlauf und erheblicher psychiatrischer und somatischer Komorbidität. Suizidale Handlungen sind häufig und die individuellen und gesundheitsökonomischen Auswirkungen der Erkrankung von deutlicher Tragweite. 2012 wurde die erste deutschsprachige evidenz- und konsensbasierte Leitlinie zur Diagnostik und Therapie bipolarer Störungen, ein gemeinsames Projekt der Deutschen Gesellschaft für Bipolare Störungen (DGBS) e. V. und der Deutschen Gesellschaft für Psychiatrie und Psychotherapie, Psychosomatik und Nervenheilkunde (DGPPN), veröffentlicht.

    ABSTRACT: Lithium is the only drug that obtained the highest level of recommendation for maintenance therapy in the recent German S3 guidelines on bipolar disorders. In addition it is the only drug with proven efficacy for the prevention of manic as well as depressive episodes in studies with a non-enriched design. Therefore, it is highly welcomed that The Lancet recently published a systematic review and meta-analysis on the risks and side effects of lithium. This is the most comprehensive review on this topic so far.The glomerular filtration rate and maximum urinary concentration ability are slightly reduced under lithium. More patients suffered from renal failure compared to controls; however, renal failure remains a very rare event. The review confirmed the well known suppressive effects of lithium on the thyroid. An increase of serum calcium could be observed relatively frequently, therefore, regular control of serum calcium under lithium therapy is recommended. A relevant increase in body weight is more frequent under lithium than under placebo but less frequent than under olanzapine. No statistically significant increase could be found for hair loss, skin disorders or major congenital abnormalities.Lithium treatment is a safe therapy when clinicians follow the established recommendations. Data indicate that a risk for renal failure exists especially in patients without regular monitoring or with too high lithium serum levels. A (subclinical) hypothyroidism is not an indication to stop administration of lithium but is an indication for l-thyroxin substitution therapy. In pregnancy the risks of continuing lithium should be balanced against the risks of stopping lithium together with the patient.

    ABSTRACT: Objective: In many countries diphenhydramine (DPH) is commonly available over the counter, frequently used, and generally regarded as a harmless drug. It is used as a sedative, antiallergic or antiemetic substance.Methods: We present a systematic review of literature search in Pubmed from 1972 to 2012 describing DPH addiction. The literature search in reveals that the addictive potential of DPH can be regarded as proved, based on cases series, eight case reports, a pharmacological overview, one uncontrolled, and one randomized, placebo controlled study. In addition we report a case of an abstinent alcoholic patient treated in our department for DPH-dependency.Conclusion: Especially when treating patients with a history of addiction, physicians should consider and check the possibility of a DPH dependency.

    ABSTRACT: The German S3-Guidelines on Bipolar Disorders have been released online in May of 2012. S3 ("step 3") stands for the currently available highest evidence based methodology guidelines can have. This includes the systematic review and appraisal of the available international scientific literature on bipolar disorders and a consensus of all relevant groups dealing with bipolar disorder on the recommendations. This article deals exclusively with pharmacotherapy of bipolar disorders. The chapter on treatment is subdivided in sections and structured in accordance to the different goals of therapy: general principles of therapy, treatment of acute mania, treatment of acute bipolar depression, maintenance therapy, specific patient groups and specific treatment constellations. Within these sections, pharmacotherapy is one therapeutic strategy. During the process of the guideline development it became clear that substantial deficits exist in many areas of treatment of this disorder and that there is great need for further research concerning many aspects of pharmacotherapy. Hence, only in rare cases recommendations achieved the highest level A ("should be done"). Nevertheless, the guidelines try to give recommendations to all clinical relevant constellations. Graphics summarize the recommendations for the initial therapeutic step and for the subsequent steps in case of insufficient response to the previous step.

    ABSTRACT: Bipolar disorder is a serious mental illness, characterized by frequent recurrences and major comorbidities. Its consequences can include suicide. An S3 guideline for the treatment of bipolar disorder was developed on the basis of a systematic literature search, evaluation of the retrieved publications, and a formal consensus-finding procedure. Several thousand publications were screened, and 611 were included in the analysis, including 145 randomized controlled trials (RCT). Bipolar disorder should be diagnosed as early as possible. The most extensive evidence is available for pharmacological monotherapy; there is little evidence for combination therapy, which is nonetheless commonly given. The appropriate treatment may include long-term maintenance treatment, if indicated. The treatment of mania should begin with one of the recommended mood stabilizers or antipsychotic drugs; the number needed to treat (NNT) is 3 to 13 for three weeks of treatment with lithium or atypical antipsychotic drugs. The treatment of bipolar depression should begin with quetiapine (NNT = 5 to 7 for eight weeks of treatment), unless the patient is already under mood-stabilizing treatment that can be optimized. Further options in the treatment of bipolar depression are the recommended mood stabilizers, atypical antipsychotic drugs, and antidepressants. For maintenance treatment, lithium should be used preferentially (NNT = 14 for 12 months of treatment and 3 for 24 months of treatment), although other mood stabilizers or atypical antipsychotic drugs can be given as well. Psychotherapy (in addition to any pharmacological treatment) is recommended with the main goals of long-term stabilization, prevention of new episodes, and management of suicidality. In view of the current mental health care situation in Germany and the findings of studies from other countries, it is clear that there is a need for prompt access to need-based, complex and multimodal care structures. Patients and their families need to be adequately informed and should participate in psychiatric decision-making. Better patient care is needed to improve the course of the disease, resulting in better psychosocial function. There is a need for further high-quality clinical trials on topics relevant to routine clinical practice.

    ABSTRACT: There is increasing evidence from ecological studies that lithium levels in drinking water are inversely associated with suicide mortality. Previous studies of this association were criticized for using inadequate statistical methods and neglecting socioeconomic confounders. This study evaluated the association between lithium levels in the public water supply and county-based suicide rates in Texas. A state-wide sample of 3123 lithium measurements in the public water supply was examined relative to suicide rates in 226 Texas counties. Linear and Poisson regression models were adjusted for socioeconomic factors in estimating the association. Lithium levels in the public water supply were negatively associated with suicide rates in most statistical analyses. The findings provide confirmatory evidence that higher lithium levels in the public drinking water are associated with lower suicide rates. This association needs clarification through examination of possible neurobiological effects of low natural lithium doses.

    ABSTRACT: Lithium ist die einzige Substanz, die in der aktuellen S3-Leitlinie zur Diagnostik und Therapie Bipolarer Störungen den höchsten Empfehlungsgrad zur Phasenprophylaxe bipolarer Störungen erhält und die in Studien ohne sog. ,,enriched design“ die Wirksamkeit zur Prävention sowohl manischer als auch depressiver Episoden zeigen konnte. Es ist daher begrüßenswert, dass in The Lancet nun mit einer systematischen Übersichtsarbeit und Metaanalyse die bislang umfangreichste Auswertung der Erkenntnisse zu unerwünschten Wirkungen und Risiken einer Lithiumbehandlung publiziert wurde.Es zeigten sich eher geringe Einschränkungen der glomerulären Filtrationsrate und der maximalen Urinkonzentrationsfähigkeit sowie eine erhöhte Rate an terminaler Niereninsuffizienz bei mit Lithium behandelten Patienten im Vergleich zu Kontrollen. Letzteres allerdings auf sehr niedrigem Niveau. Die bekannten thyreostatischen Lithiumeffekte wurden bestätigt. Relativ häufig kommt es zum Ansteigen des Kalziumspiegels, weshalb auch dieser regelmäßig während einer Lithiumtherapie kontrolliert werden sollte. Eine relevante Gewichtszunahme tritt signifikant häufiger auf als unter Placebo, aber seltener als unter Olanzapin. Kein statistisch signifikant häufigeres Auftreten unter Lithium konnte für Haarausfall, Hautveränderungen und kongenitale Fehlbildungen gefunden werden.Unter Beachtung der etablierten Anwendungsempfehlungen stellt eine Lithiumbehandlung eine sichere Therapie dar. Es gibt Hinweise darauf, dass die gefürchtete terminale Niereninsuffizienz vor allem bei mangelhaft kontrollierter oder mit zu hohen Serumspiegeln durchgeführter Behandlung auftritt. Eine (latente) Hypothyreose ist kein Grund zum Absetzen von Lithium, sondern eine Indikation für eine L-Thyroxin-Behandlung. Im Falle einer Schwangerschaft unter Lithium sollten Risiken der Fortführung von Lithium mit denen des Absetzens gemeinsam mit der Schwangeren abgewogen werden.
