Active clinical trials for "Depressive Disorder"

The purpose of this study is to determine the efficacy of the use of intravenous low-dose ketamine in the treatment of treatment-resistant depression (TRD), as well as the changes in Glutamate neurotransmission and inflammatory serum markers.

This study evaluates the effects of the Positive Psychotherapy on depressive symptoms and on happiness compared with regular cognitive behavioral therapy.

Regarding the direct costs and the social value of depression, the decision of an antidepressant treatment prescription must be optimized as much as possible. The development of a personalized medicine in psychiatry may reduce treatment failure, intolerance or resistance, and hence burden and costs of affective disorders. There is hope that biomarkers will be found to guide treatment selection. It might be of decisive interest to be able to assess an individual's metabolism activity. We propose here to explore the relationship between the activity of drug-metabolizing enzymes (DME) and transporters- assessed by a phenotypic approach and the efficacy of antidepressants. We will focus on venlafaxine (V) that provides a reasonable second-step choice for patients with depression and is used extensively in psychiatric practice, and the metabolism of which involves several cytochromes (CYP) P450 enzymes and the transporter P-gp. Thus, the primary objective of this study is to study the correlation between the concentration of V and its metabolite ODesmethylV (V+ODV) and drug metabolism variability assessed by a phenotypic approach, in patients with major depressive disorder and MADRS ≥ 20 despite 4 weeks of V at 150mg or less

The primary aim is to evaluate the effectiveness of an intervention based on a psychoeducational program carried out by primary care nurses, to improve the rate of remission and response of depression in patients with physical chronic illness (diabetes, COPD, asthma and / or ischemic heart disease). Secondarily, to assess the cost-effectiveness of the intervention, the effectiveness to improve the control of physical pathology, the impact on quality of life and the feasibility of the intervention. Methods: a multicentre, randomized clinical trial, with two groups and 1 year follow-up evaluation. Economic evaluation study. We will study 504 patients (252 in each group), over 50 years assigned to 25 primary care teams (PC) from Catalonia (urban, semi-urban and rural) with major depression and with at least one of the diseases: diabetes mellitus type 2, chronic obstructive pulmonary disease, asthma, and / or ischemic heart disease. They will be distributed randomly into two groups. The intervention group will participate in psychoeducational groups: 12 weekly 90-minute sessions led by two nurses from PC, consisting of health education on chronic physical illness and depressive symptoms. Main measurements: clinical remission of depression and / or response to intervention (Beck depression inventory: BDI-II). Secondary measures: improvement in control of chronic disease (blood test and physical parameters), drug compliance (test Morinsky-Green and number of packaging), quality of life (EQ-5D), medical service utilization (appointments and hospital admissions due to complications) and feasibility of the intervention (satisfaction and compliance). Evaluations will be masked and conducted at 0, 3 and 12 months. At 6 months, patients will receive a call from nurses.

The aim of the study is the examination of effectiveness and cost-effectiveness of a telephone-based psychotherapy (Tel-PT) for depression compared to treatment as usual in primary care.

The aim of this study is to evaluate the efficacy of N-acetylcysteine (NAC) add-on to antidepressant medication in treating patients who do not relieve during standard antidepressant treatment for 6 weeks at least. Meanwhile, secondary outcomes will include changes in some biomarkers and on specifically local brain activity (functional Magnetic Resonance Imaging, fMRI) and white matter integrity (Diffusion Tensor Imaging, DTI). The hypothesis of this study is that NAC has positive effects on refractory major depressive disorder patients with increased inflammatory activity.

The objective of the present project is to study the differential effectiveness of three brief self-applied via the Internet interventions for mild to moderate depression: a global protocol composed of several therapeutic components (psychoeducation, cognitive restructuring, behavioral activation, positive psychology, and relapse prevention), a protocol just based on behavioral activation (BA), and a protocol just based on positive psychology (PP). The purpose is to know the specific contribution of each therapeutic components in the treatment of depression.

The primary purpose is to compare with resting fMRI the functional networks of rest (RTS) in unipolar depression and in bipolar depression. Hypothesis : the main objective of this work is to compare with the rest fMRI the Rest Functional Networks (RFN) in the unipolar depression and in the bipolar depression in order to identify specific biomarkers for each affection. The general hypothesis of this work is that intra- and inter RFN connectivity is different between bipolar patients and unipolar patients. Specifically the investigators assume that connectivity within the default mode network (including ventral mediofrontal cortex, subgenual cingulate cortex, inferior parietal cortex, posterior cingulate cortex) will be increased in unipolar patients compared to bipolar patients.

Depression is a frequent disease and a serious public health problem, of which suicide is the most severe complication. Its treatment is based on the introduction of antidepressant which not only proposes a significant delay in the relief of symptoms but also by the phenomenon of lifting of inhibition can increase the suicidal risk during the initiation phase. Therefore there is a major interest in proposing a monitoring of these dark and suicidal ideas, immediately after the implementation of such treatment as well as other symptoms of depression. Thus, the aim of this study is to identify the mechanisms underlying this increase in dark and suicidal ideas in this context.

The study aims to explore the effectiveness of psycho-behavioral intervention on depressive symptoms among older adults with chronic heart failure. Meanwhile, the effect on cardiac function and quality of life will also be explored.
