RESUMEN

This report presents the rationale and design of a multi-center clinical trial that examines the efficacy and safety of antipsychotic combination treatment in acutely ill schizophrenia patients compared to antipsychotic monotherapy. Antipsychotic combination treatment is common in clinical practice worldwide, despite clinical guidelines generally not recommending such practice due to lacking evidence for its efficacy and safety. Olanzapine has a related chemical structure and comparable receptor-binding profile as clozapine, which demonstrated superior efficacy in combination studies, but has a more unfavorable side-effect profile compared to olanzapine. Amisulpride and olanzapine have shown promising therapeutic efficacy in meta-analyses in monotherapy for people with schizophrenia. Combining amisulpride and olanzapine, complementary receptor-binding properties may enhance efficacy and possibly reduce (or at least not augment) side effects due to the different receptor profiles and metabolization pathways. Accordingly, we hypothesize that patients treated with amisulpride plus olanzapine show greater improvement on the Positive and Negative Syndrome Scale total score after 8 weeks versus either monotherapy. A randomized, double-blind controlled trial is performed at 16 German centers comparing flexibly dosed monotherapy of oral amisulpride (400-800 mg/day), and olanzapine (10-20 mg/day) and amisulpride-olanzapine co-treatment. Sample size was calculated to be n = 101 per treatment arm, assuming an effect size of 0.500 and a two-sided alpha = 0.025 and beta = 0.90. Recruitment for this trial started in June 2012. Until December 2018, 328 patients have been randomized. Trial conduct has been extended to reach the projected sample size. Publication of the study results is expected in 2019 informing an evidence-based recommendation regarding specific antipsychotic combination treatment.

RESUMEN

BACKGROUND: Patients in palliative care need rapid-acting pharmacological options for psychological distress. N-methyl-D-aspartate antagonist ketamine is known to have a fast onset of anti-depressant and anxiolytic action. Its S-enantiomer S-ketamine (or esketamine) is an analgesic used as a routine treatment for refractory pain as an intravenous infusion (0.25 mg/kg over 45 min). This study investigates whether S-ketamine pain therapy has a positive impact on psychological distress caused by anxiety and depression in palliative care. METHODS: Patient routine data from a palliative care unit of a tertiary care hospital were used in a retrospective analysis after positive ethics approval. Eight patients, who received analgesic S-ketamine treatment, were compared to a control group matched by gender and age. The main analysis was conducted using three-way mixed MANOVA followed by two-way mixed ANOVA. Target variables were the values for anxiety and depression in the state-trait anxiety-depression inventory STADI. The predictor variables were the time of measurement before (T1) and after (T2) S-ketamine application and group membership. RESULTS: Comparison of the S-ketamine group (n = 8; 4 male, 4 female; average age 52 years) with the control group (n = 8; 3 male, 5 female; average age 55 years) revealed a significant multivariate effect on anxiety and depression F(1, 14) = 4.78; p = 0.046; r = 0.50. The univariate comparisons showed a significant reduction of the anxiety scores from T1 to T2 in the S-ketamine group compared to the control group F(1, 14) = 10.14; p = 0.007; r = 0.65. With regard to depression, there was no significant reduction from T1 to T2 in the group comparison F(1, 14) = 1.60; p = 0.23; r = 0.32. No long-lasting effects on pain were found. CONCLUSIONS: Our findings show that psychological distress of patients in palliative care may improve after a single administration of S-ketamine, which mainly alleviates anxiety in those patients. Limitations of this study arise from non-randomization, retrospective analysis and low sample size. Therefore, further prospective and ideally randomized studies are necessary.

RESUMEN

Objective: It is well established that long-term hypothyroidism is associated with cognitive deficits. Based on recent literature, we hypothesized that pharmacologically induced euthyroidism would lead to improved cognitive performance compared to a hypothyroid state. Methods: We analyzed data from 14 nondepressed thyroidectomized female patients after differentiated thyroid carcinoma during hypothyroidism (due to a four-week withdrawal of thyroid hormone, T1) and euthyroidism brought about by substitution with L-thyroxine (T2). At both measurement points, patients completed a cognitive test battery as our dependent measure and Beck's Depression Inventory to control depressive states. Results: A Wilcoxon signed-rank tests revealed a significant improvement in the Rey­Osterrieth complex figure test (cognitive reproduction), Z = −3.183, p = 0.001, and the D2 concentration score, Z = −1.992, p = 0.046 in euthyroidism compared to hypothyroidism. Conclusions: Our results confirm that hormone replacement therapy with L-thyroxine promotes cognitive reproduction and concentration in thyroidectomized female patients after differentiated thyroid carcinoma.

RESUMEN

BACKGROUND: Psychotropic drugs are the cornerstone of schizophrenia treatment, often requiring lifelong treatment. Data on pharmacotherapy in inpatient settings are lacking. METHODS: Prescription data of schizophrenic inpatients within the time period 2000-2015 were obtained from the database of the Drug Safety Program in Psychiatry (AMSP). Data were collected at 2 index dates per year; the prescription patterns and changes over time were analyzed. RESULTS: Among 30 908 inpatients (mean age 41.6 years, 57.8% males), the drug classes administered most often were antipsychotics (94.8%), tranquilizers (32%), antidepressants (16.5%), antiparkinsonians (16%), anticonvulsants (14.1%), hypnotics (8.1%), and lithium (2.1%). The use of second-generation antipsychotics significantly increased from 62.8% in 2000 to 88.9% in 2015 (P < .001), whereas the prescription of first-generation antipsychotics decreased from 46.6% in 2000 to 24.7% in 2015 (P < .001). The administration of long-acting injectable antipsychotics decreased from 15.2% in 2000 to 11.7% in 2015 (P = .006). Clopazine was the most often used antipsychotic, having been used for 21.3% of all patients. Polypharmacy rates (≥5 drugs) increased from 19% in 2000 to 26.5% in 2015. Psychiatric polypharmacy (≥3 psychotropic drugs) was present in 44.7% of patients. CONCLUSIONS: Combinations of antipsychotics and augmentation therapies with other drug classes are frequently prescribed for schizophrenic patients. Though treatment resistance and unsatisfactory functional outcomes reflect clinical necessity, further prospective studies are needed on real-world prescription patterns in schizophrenia to evaluate the efficacy and safety of this common practice.

RESUMEN

PURPOSE/BACKGROUND: The present study was conducted to investigate the difference in attitudes toward psychiatric drugs, long-term medication, and depot formulations between psychiatric patients and patient-related groups and the German general public. METHODS/PROCEDURES: Different groups (n = 50 patients, n = 34 relatives of patients, n = 42 psychiatrists, n = 70 medical students, and n = 58 psychiatric nursing professionals) were surveyed using a questionnaire to investigate their attitude toward depot medication and compared with matched participants from the German general public. FINDINGS/RESULTS: Patients did not differ from their matched controls regarding their attitude toward potential reasons to reject a depot, whereas psychiatrists (P = 0.002) and nursing staff (P = 0.003) were more concerned about patients fearing an injection than their matched controls. IMPLICATIONS/CONCLUSIONS: Psychiatrists and psychiatric nurses were significantly more concerned about giving an (intragluteal) injection because of concerns about patients' fears of this administration method than their matched controls. In contrast, patients' concerns about receiving an injection did not differ from their matched controls. Furthermore, we found that psychiatrists tended to believe that giving an injection might be time-consuming than giving oral medication. These results may emphasize the fact that the low rate of depot medication use is derived from subjective reservations of medical staff rather than actual negative attitudes or fears of patients.

RESUMEN

BACKGROUND: Impaired subjective well-being in schizophrenia patients treated with antipsychotics has often been linked inter alia to the antidopaminergic effects of medication. Thus, it is important to capture the association between striatal dopamine D2 receptor occupancy (D2-RO) and global subjective well-being. We examined this association using data from our multicenter, randomized, double-blind Neuroleptic Strategy Study (NeSSy). METHODS: An innovative double randomization process was used for allocation of patients to the specific treatment groups. Plasma drug concentrations were measured after 6 and 24 weeks of treatment to obtain the estimated D2-RO (eD2-RO) relative to literature values. We made an exploratory analysis of associations between eD2-RO and subjective well-being scores. One hundred two blood samples from 69 patients were available for the analysis. Because of the lack of a satisfactory occupancy model for quetiapine, only haloperidol, flupentixol, and olanzapine treatment groups were pooled, whereas aripiprazole data were analyzed separately, because of its partial agonistic properties. RESULTS: In the pooled antagonist group, eD2-RO correlated negatively with the summarized well-being score. In a more detailed analysis, this association could be confirmed for all first-generation antipsychotic-treated patients, but not for the separate second-generation antipsychotic groups. In the aripiprazole group, higher eD2-RO was associated with impaired physical well-being, but had no association with mental well-being. CONCLUSIONS: Our results suggest that high plasma levels and consequently high occupancy at D2 receptors are disadvantageous for subjective well-being, as distinct from the objective extrapyramidal side effects. To minimize patients' malaise, which disfavors adherence, implementation of therapeutic drug monitoring in the clinical routine may be useful.

RESUMEN

BACKGROUND: Treatment of schizophrenia with depot medication has advantages compared with oral medication, and among these include an improved compliance. Despite such advantages, prescription rates in many European countries are lower than 20%. The aim of this survey was to study the attitudes toward depot medication among the German general population. To the best of our knowledge, only selective samples have been investigated up until now. METHODS: A representative sample of 754 people were interviewed via telephone by a professional market research and polling organization. The questionnaire queried demographic characteristics, experience with medication, and the treatment of mental disorders. Subjects' attitudes toward medication in general, long-term medication, and depot medication were surveyed. RESULTS: Most (66.7%) of the subjects stated that they would be willing to receive depot medication. Subjects who experienced the treatment of mental disorders were more likely to be willing to receive depot medication. Among the reasons for not using depot medication, "fear of injection" (66.3%) and "more self-control when taking medication as tablets" (48.9%) were stated as the most frequent reasons. CONCLUSIONS: This study found a good acceptance of antipsychotic depot medication among the German general population in terms of willingness to receive such treatment. We argue that the clinical practitioners' assumptions that depot formulations would be refused by many patients are unsubstantiated.

RESUMEN

Auditory verbal hallucinations (AH) are core symptoms of schizophrenia. They are often severely distressing and refractory to therapy. Their perception is associated with increased activity in temporoparietal areas of the brain. Repetitive transcranial magnetic stimulation (rTMS) can reduce focal brain hyperactivity and has been shown to ameliorate AH. However, controlled multicenter clinical trials are still missing, effect sizes are moderate, and the treatment with rTMS is time consuming. Continuous theta burst stimulation (cTBS) is a quicker and potentially more effective technique to reduce cortical hyperactivity. First case and pilot studies indicate effectiveness in the treatment of AH. In this randomized, sham-controlled, double-blind multicenter clinical trial, 86 patients with schizophrenia spectrum disorder will be randomized to either cTBS or sham to the left and right temporoparietal cortex during three consecutive weeks (15 sessions totally). In each session, both hemispheres will be stimulated sequentially. The order in the first session (left-right or right-left, respectively) will be determined by randomization and alternated in all following sessions. Primary outcome is the reduction of mean PSYRATS-AH score after cTBS as compared to sham treatment. Follow-up measurements will be performed 1, 3 and 6 months after the end of the treatment. Statistical analysis will be based on the intention-to-treat population including all randomized patients using an analysis of covariance. This multicenter-controlled clinical trial will be able to provide decisive evidence for the efficacy of cTBS in the treatment of AH. The results will be suitable to clarify the role of this innovative, pathophysiology-based therapeutic approach in treatment guidelines for AH.

RESUMEN

Due to the efficacy of electroconvulsive therapy (ECT) in the guideline-based treatment of therapy-resistant depressive episodes and the clinical significance of cognitive impairments, it is necessary to optimize the management of potential side effects. As cognitive side effects of the treatment combined with impairments resulting from the depression may lead to a reduction in the ability to function in social contexts and reduce subjective wellbeing, comprehensive information about and monitoring of potential side effects is essential. In this review we present the clinical relevance and measurement of cognitive side effects that may occur during electroconvulsive therapy. The individual characteristics of the patient as well as the technical and pharmacological parameters that influence the effect of ECT on cognition will be discussed. Furthermore, the recommendations of national and international treatment guidelines for the monitoring of cognitive side effects will be summarized.After ECT, impairments of global cognition, and anterograde as well as retrograde amnesia may occur. While the first two side effects appear to be transient, the extent of retrograde amnesia, particularly for autobiographical information, is not yet well understood and may potentially be present for a longer period. A controversial issue in this context is the question whether there are appropriate instruments for the monitoring of reduction in cognitive performance. In clinical context, a number of different measures are used, and in many cases, monitoring is omitted due to lack of time and methodological uncertainty. Current national and international guidelines make very different suggestions about the monitoring of cognitive side effects during ECT and in German-speaking regions no concrete recommendations are available. In this context, we recommend a revision of current guidelines and identify future areas of research that would further our understanding of the effects of ECT on cognition. These may enable us to keep an eye on these deficiencies better as well as allow us to identify patients that may have a higher risk of developing such impairments.

RESUMEN

Background: Treatment algorithms are considered as key to improve outcomes by enhancing the quality of care. This is the first randomized controlled study to evaluate the clinical effect of algorithm-guided treatment in inpatients with major depressive disorder. Methods: Inpatients, aged 18 to 70 years with major depressive disorder from 10 German psychiatric departments were randomized to 5 different treatment arms (from 2000 to 2005), 3 of which were standardized stepwise drug treatment algorithms (ALGO). The fourth arm proposed medications and provided less specific recommendations based on a computerized documentation and expert system (CDES), the fifth arm received treatment as usual (TAU). ALGO included 3 different second-step strategies: lithium augmentation (ALGO LA), antidepressant dose-escalation (ALGO DE), and switch to a different antidepressant (ALGO SW). Time to remission (21-item Hamilton Depression Rating Scale ≤9) was the primary outcome. Results: Time to remission was significantly shorter for ALGO DE (n=91) compared with both TAU (n=84) (HR=1.67; P=.014) and CDES (n=79) (HR=1.59; P=.031) and ALGO SW (n=89) compared with both TAU (HR=1.64; P=.018) and CDES (HR=1.56; P=.038). For both ALGO LA (n=86) and ALGO DE, fewer antidepressant medications were needed to achieve remission than for CDES or TAU (P<.001). Remission rates at discharge differed across groups; ALGO DE had the highest (89.2%) and TAU the lowest rates (66.2%). Conclusions: A highly structured algorithm-guided treatment is associated with shorter times and fewer medication changes to achieve remission with depressed inpatients than treatment as usual or computerized medication choice guidance.

RESUMEN

BACKGROUND: The 'gold standard' for clinical studies is a randomised controlled trial usually comparing specific treatments. If the scientific study expands to strategy comparison with each strategy including various treatments, the research problems are increasingly complicated. The strategy debate in the psychiatric community is the starting point for the development of our new design. It is widely accepted that second-generation antipsychotics are the therapy of choice in the treatment of schizophrenia. However, their general superiority over first-generation antipsychotics could not be demonstrated in recent randomised controlled trials. Furthermore, we are becoming increasingly aware that the experimental conditions of randomised controlled trials, as in the European First Episode Schizophrenia Trial and Clinical Antipsychotic Trials of Intervention Effectiveness Phase 1 studies, may be inappropriate for psychiatric treatments. The high heterogeneity in the patient population produces discrepancies between daily clinical perception and randomised controlled trials results. The patient-oriented approach in the Cost Utility of the Latest Antipsychotic drugs in Schizophrenia Study reflects everyday clinical practice. The results, however, are highly dependent on the physicians' preferences. The goal of the design described here is to take an intermediate path between randomised controlled trials and clinical studies such as Cost Utility of the Latest Antipsychotic Drugs in Schizophrenia Study, combining the advantages of both study types. METHODS: The idea is to randomise two treatment pairs each consisting of one first-generation antipsychotic and one second-generation antipsychotic in a first step and subsequently, to involve the investigators in deciding for a pair most appropriate to the patients' needs and then to randomise the allocation to one drug (first-generation antipsychotic or second-generation antipsychotic) of that chosen pair. This idea was first implemented in the clinical trial, the Neuroleptic Strategy Study, with a randomised design comparing efficacy and safety of two different strategies: either to use first-generation antipsychotics (haloperidol and flupentixol) or second-generation antipsychotics (olanzapine, aripiprazole and quetiapine) in patients suffering from schizophrenia. RESULTS: In the course of the Neuroleptic Strategy Study, feasibility of this design was demonstrated. All aspects of the new design were implemented: randomisation process, documentation of responses from investigators as well as patients and drug logistic experience. In implementing the design, furthermore, we could investigate its theoretical properties. The physicians' preferences for specific drugs used for the respective patients were analysed. CONCLUSION: The idea of patient-oriented randomisation can be generalised. In light of the heterogeneity and complexity of patient-drug interaction, this design should prove particularly useful.

RESUMEN

BACKGROUND: The evidence for repetitive transcranial magnetic stimulation (rTMS) to treat negative symptoms in schizophrenia (SCZ) is increasing, although variable response rates remain a challenge. Subject´s sex critically influences rTMS´ treatment outcomes. Females with major depressive disorder are more likely to respond to rTMS, while SCZ data is scarce. METHODS: Using data from the 'rTMS for the Treatment of Negative Symptoms in Schizophrenia' (RESIS) trial we assessed the impact of sex on rTMS´ clinical response rate from screening up to 105 days after intervention among SCZ patients. The impact of resting motor threshold (RMT) on response rates was also assessed. RESULTS: 157 patients received either active or sham rTMS treatment. No significant group differences were observed. Linear mixed model showed no effects on response rates (all p > 0.519). Apart from a significant sex*time interaction for the positive subscale of the positive and negative syndrome scale (PANSS) scores (p = 0.032), no other significant effects of sex on continuous PANSS scores were observed. RMT had no effect on response rate. CONCLUSION: In the largest rTMS trial on the treatment of SCZ negative symptoms we did not observe any significant effect of sex on treatment outcomes. Better assessments of sex-related differences could improve treatment individualisation.

RESUMEN

Hyponatremia is a common phenomenon in psychiatry occurring as an adverse effect to drugs or following polydipsia. We performed a retrospective in-depth analysis of hyponatremia cases in a large unselected population of psychiatric inpatients. During a 3-year period, all cases of hyponatremia were identified among patients admitted to a large psychiatric state and university hospital by the institution's electronic laboratory database. Demographic, treatment-related, and laboratory data were obtained by consecutive chart review, respectively. Hyponatremia occurred in 347 (4.9%) of 7113 cases, of which the majority (78%) displayed only a mild manifestation. Symptoms were recorded in 28.8% of cases, already occurred in mild forms, and comprised gait impairment (45%, including falls), confusion (30%), sedation (26%), and dyspepsia (41%). Age, female sex, nonpsychiatric drug polypharmacy-particularly with thiazides and/or angiotensin-converting enzyme inhibitors-and diagnosis of a mood disorder were associated with more severe hyponatremia, respectively. The proportion of hyponatremic patients treated with venlafaxine, trazodone, carbamazepine, oxcarbazepine, and first-generation antipsychotics, respectively, was significantly higher in the hyponatremia sample than in the normonatremic population. This was, surprisingly, not the case with selective serotonin reuptake inhibitors or any other antidepressant drug class. We found prescription with second-generation antipsychotics to be significantly associated with less severe hyponatremia.Hyponatremia may be mainly attributed to the syndrome of inappropriate antidiuretic hormone secretion, as indicated by decreased serum osmolarity in our sample. Besides old age and female sex, treatment with certain drugs-rather than whole drug classes-carries a substantially increased risk.

RESUMEN

Metabolic syndrome (MetS) is an important risk factor for the development of type-2 diabetes and coronary artery disease. We aimed to compare the MetS prevalence in patients with borderline personality disorder (BPD) with comparison subjects followed in primary care from a similar region. One hundred and thirty-five BPD patients according to DSM-IV diagnostic criteria were compared to 1009 subjects from primary care. We used the American Heart Association/National Heart, Lung and Blood Institute criteria to determine the rate of MetS. The age-standardized prevalence of MetS was more than double in patients with BPD compared to comparison subjects (23.3 vs. 10.6 %, p < 0.05). Regarding individual MetS criteria, hyperglycemia was significantly more prevalent in both genders (p < 0.05). Abdominal obesity (p < 0.05) and hypertriglyceridemia (p < 0.05) were significantly higher only in women with BPD. Within BPD patients, an increased rate of MetS was associated with higher BMI (p = 0.004), age (p = 0.03), treatment with second-generation antipsychotics (quetiapine, olanzapine and clozapine; p = 0.032), dysthymia (p = 0.031), panic disorder (p = 0.032), benzodiazepine dependency (p = 0.015) and binge eating disorder p = 0.02). Our results demonstrate an increased MetS rate, dysregulated glucose and lipid metabolism in patients with BPD. Cardiometabolic monitoring and careful screening for physical health conditions among people with BPD is warranted.

RESUMEN

OBJECTIVE: People with psychiatric diseases have a severely increased risk for physical morbidity and premature death from physical diseases. The aims of the study were to investigate the occurrence of cardiovascular diseases (CVD), diabetes (DM) and obesity in schizophrenia and depression in three different geographical areas - Asia (Japan), Africa (Nigeria) and Western Europe (Switzerland, Germany and Denmark) - and to search for possible transcultural differences in these correlations, which would also reflect the differences between low-income areas in Africa (Nigeria) and high-income areas in Europe and Japan. METHOD: Patients with International Classification of Diseases (ICD-10) F2 diseases (schizophrenia spectrum disorders) and F3 diseases (affective disorders) admitted to one Nigerian, one Japanese, two Swiss, two German and six Danish centres during 1 year were included. Physical diseases in accordance with ICD-10 were also registered. Psychiatric and physical comorbidity were calculated and standardized rate ratio incidences of background populations were our primary measures. RESULTS: Incidence rate ratios were increased for both CVD, DM and overweight in both F2 and F3 in all cultures (Western Europe, Nigeria and Japan) within the same ranges (however, the Japanese results should be interpreted conservatively owing to the limited sample size). Overweight among the mentally ill were marked in Nigeria. A parallelism of the incidence of overweight, CVD and diabetes with the occurrence in background populations was seen and was most marked in overweight. CONCLUSIONS: Overweight, CVD and DM were increased in schizophrenia spectrum disorders and affective disorders in all three cultures investigated (Western Europe, Nigeria and Japan). Lifestyle diseases were also seen in Nigeria and Japan. The results from this study indicate that cultural background might be seen as an important factor in dealing with lifestyle diseases among people with a severe mental illness, as it is in the general population.

RESUMEN

Previous studies on the association between affective disorders and the metabolic syndrome yielded inconclusive results. Therefore, we examined the prevalence of the metabolic syndrome in 230 men and women with unipolar major depressive disorder during inpatient treatment and compared it to 1,673 subjects from primary care from a similar region in northern Germany. We used the AHA/NHBLI criteria to determine the rate of metabolic syndrome (MetS) and each single criterion of MetS in both groups. The age-standardized prevalence of MetS was 2.4× as high in patients with major depressive disorder (MDD) compared with data from comparison subjects (41.0% vs. 17.0%). With respect to the single criteria, elevations were found in MDD patients for fasting glucose and triglycerides in both genders, and waist circumference in women. Men in the patient and the comparison groups were found to have higher rates of increased fasting glucose and triglycerides than women in the respective groups. Factors associated with the MetS in MDD patients comprise body mass index and the severity of depression. Our results demonstrate an increased prevalence of the MetS in men and women with MDD. Interventions for the frequently untreated metabolic abnormalities and careful screening for physical health conditions among people with MDD are warranted.

RESUMEN

BACKGROUND: Combining antipsychotics is common in schizophrenia treatment, despite evidence-based guidelines generally not recommending such practice. Otherwise, evidence remains inconclusive, especially regarding specific combinations. The trial aimed to test whether a combination of amisulpride plus olanzapine is more effective than either intervention as a monotherapy. METHODS: A multicentre, 16-week, randomised, double-blind, controlled trial was done at 16 psychiatric in-patient centres throughout Germany. Inclusion criteria were adults aged 18-65 years with non-first episode schizophrenia or schizoaffective disorder and with a Positive and Negative Syndrome Scale (PANSS) total score of at least 70 and at least two items of the positive symptoms subscale rated at least 4. Patients were randomly assigned to receive 16 weeks of treatment with either amisulpride plus olanzapine, amisulpride plus placebo, or olanzapine plus placebo (1:1:1), and block randomisation was stratified by study site. To keep patients and investigators masked throughout the duration of the trial, amisulpride, olanzapine, and placebo were administered as identical capsules. Flexibly dosed monotherapy of oral amisulpride (amisulpride plus placebo, 200-800 mg per day) or olanzapine (olanzapine plus placebo, 5-20 mg per day) was compared with a combination of amisulpride plus olanzapine. The primary outcome was symptom reduction measured by the PANSS total score after 8 weeks, in the modified intention-to-treat population (all patients randomly assigned to an intervention and receiving at least one study drug dose). As determined a priori, group differences were examined by t tests (Bonferroni-Holm-adjustment) followed by pre-planned Bayesian analyses as well as imputation methods based on mixed models to account for missing values and post-hoc ANCOVA adjusting for PANSS baseline scores. The study was registered on ClinicalTrials.gov, NCT01609153; the German Clinical Trials Register, DRKS00003603; and the European Union Drug Regulating Authorities Clinical Trials Database, EudraCT-No. 2011-002463-20. FINDINGS: Between June 15, 2012, and Dec 15, 2018, 13 692 patients were assessed for eligibility. 13 364 patients were excluded (including for not meeting inclusion criteria, declining to participate, or inappropriate reasons for changing pharmacological treatment), and 328 were then randomly assigned to an intervention group. 112 patients were randomly assigned to receive amisulpride plus olanzapine, 109 were randomly assigned to receive amisulpride plus placebo, and 107 were randomly assigned to receive olanzapine plus placebo. 321 patients were analysed for the primary outcome in the modified intention-to-treat population after exclusion of screening failures and patients who did not receive the intervention (110 for amisulpride plus olanzapine, 109 for amisulpride plus placebo, and 102 for olanzapine plus placebo). Among the 321 patients who were randomly assigned to intervention groups and analysed for the primary outcome, 229 (71%) were male, 92 (29%) were female; the mean age was 40·2 years (SD 11·7); and 296 (92%) were White and 25 (8%) were classified as other ethnicity. PANSS total score improved significantly more at 8 weeks in the amisulpride plus olanzapine group (-29·6 [SD 14·5]) than in the olanzapine plus placebo group (-24·1 [13·4], p=0·049, Cohen's d=0·396). A significant difference was not observed in reduction of PANSS total score between the amisulpride and olanzapine group compared with the amisulpride and placebo group (-25·2 [SD 15·9], p=0·095, Cohen's d=0·29). After 8 weeks and 16 weeks, sexual dysfunction, weight, and waist circumference increase were significantly higher for patients receiving amisulpride plus olanzapine than for those receiving amisulpride plus placebo, with no differences in serious adverse events. Two patients died during study participation; one randomly assigned to the amisulpride plus olanzapine group, and one assigned to the olanzapine plus placebo group (both assessed with no relation to treatment). INTERPRETATION: The advantages of amisulpride plus olanzapine have to be weighed against a higher propensity for side-effects. The use of this specific combination therapy could be an alternative to monotherapy in certain clinical situations, but side-effects should be considered.

RESUMEN

BACKGROUND AND HYPOTHESIS: Meta-analyses have shown that the majority of patients with schizophrenia who have not improved after 2 weeks of treatment with an antipsychotic drug are unlikely to fully respond later. We hypothesized that switching to another antipsychotic with a different receptor binding profile is an effective strategy in such a situation. STUDY DESIGN: In total, 327 inpatients with an acute exacerbation of schizophrenia were randomized to double-blind treatment with either olanzapine (5-20 mg/day) or amisulpride (200-800 mg/day). Those patients who had not reached at least 25% Positive-and-Negative-Syndrome-Scale (PANSS) total score reduction from baseline after 2 weeks (the "non-improvers") were rerandomized double-blind to either staying on the same compound ("stayers") or to switching to the other antipsychotic ("switchers") for another 6 weeks. The primary outcome was the difference in the number of patients in symptomatic remission between the combined "switchers" and the "stayers" after 8 weeks of treatment, analyzed by logistic regression. STUDY RESULTS: A total of 142 nonimprovers were rerandomized at week two. 25 (45.5 %) of the 'stayers' compared to 41 (68.3 %) of the "switchers" reached remission at endpoint (p = .006). Differences in secondary efficacy outcomes were not significant, except for the PANSS negative subscore and the Clinical-Global-Impression-Scale. "Switchers" and "stayers" did not differ in safety outcomes. CONCLUSIONS: Switching "non-improvers" from amisulpride to olanzapine or vice-versa increased remission rates and was safe. The superiority in the primary outcome was, however, not paralleled by significant differences in most secondary efficacy outcomes and the effect was only apparent at the last visit making replications of longer duration necessary.

RESUMEN

INTRODUCTION: Non-invasive brain stimulation techniques such as repetitive transcranial magnetic stimulation (rTMS) offer a promising alternative to psychotherapeutic and pharmacological treatments for depression. This paper aims to present a practical guide for its clinical implementation based on evidence from the literature as well as on the experience of a group of leading German experts in the field. METHODS: The current evidence base for the use of rTMS in depression was examined via review of the literature. From the evidence and from clinical experience, recommendations for the use of rTMS in clinical practice were derived. All members of the of the German Society for Brain Stimulation in Psychiatry and all members of the sections Clinical Brain Stimulation and Experimental Brain Stimulation of the German Society for Psychiatry, Psychotherapy, Psychosomatics and Mental Health were invited to participate in a poll on whether they consent with the recommendations. FINDINGS: Among rTMS experts, a high consensus rate could be identified for clinical practice concerning the setting and the technical parameters of rTMS treatment in depression, indications and contra-indications, the relation of rTMS to other antidepressive treatment modalities and the frequency and management of side effects.

RESUMEN

Central nervous system (CNS) monoamine deficits have been linked to a number of pathological conditions such as major depressive disorder. Individual biological variations in 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA) and 3-methoxy-4-hydroxyphenylglycol (MHPG) might account for the variation in responses of neurotransmitter systems observed after the administration of clomipramine. The prolactin response to clomipramine has been widely used to assess CNS functioning. This open label study investigates the prolactin response induced by clomipramine in the plasma of healthy volunteers and whether it is related to changes in monoamine metabolites. The effects of clomipramine challenge on prolactin, 5-HIAA, HVA and MHPG were measured in 12 healthy volunteers. Samples were drawn directly before and 50 min after clomipramine infusion. A statistically significant increase in serum prolactin concentrations was measured in women 50 min after CMI infusion, but not in men. We found no significant increases in the serum monoamine metabolite concentrations 50 min after CMI infusion. Changes in HVA and 5-HIAA correlated statistically significantly and positively with the amount of prolactin release in the whole sample. Furthermore, positive correlations were found between ∆(50-0 min) 5-HIAA and ∆(50-0 min) HVA, although we did not find a correlation between ∆(50-0 min) prolactin and ∆(50-0 min) MHPG after clomipramine challenge. The pronounced prolactin release in healthy adult women might indicate a higher physiological sensitivity. Correlations between intra-individual changes in HVA, 5-HIAA and serum prolactin might indicate a central nervous effect of clomipramine on monoamine turnover. We conclude that monoamine changes in relation to prolactin response after clomipramine challenge may be suitable for characterizing the relationship between central serotonergic and dopaminergic function.
