1. To determine the influencing factors of modified electroconvulsive therapy (MECT); 2. To determine the influencing factors and reversibility of the cognitive impairment caused by MECT; 3. To determine the duration of efficacy of MECT and its affecting factors.
The investigators have observed in an open trial that a single session of whole body hyperthermia (WBH) induced rapid antidepressant effects that persisted for at least a week in patients with major depression (MDD) severe enough to warrant inpatient hospitalization. In addition to reducing depression, the single session of WBH induced a prolonged reduction in mean core body temperature, consistent with basic science data from our group suggesting that hyperthermia activates a skin-to-brain pathway that have been shown in animals to be important for mood and body temperature regulation. Consistent with this known anatomy in our preliminary study in depressed patients, reductions in core body temperature were highly correlated with reductions in depressive symptoms over the same time period (one week post WBH). Moreover, patients with higher mean core body temperature prior to treatment had enhanced antidepressant effects. Because increased body temperature is an outcome of poor functioning in the skin-to-brain pathway activated by WBH our data suggests that WBH may actually sensitize this pathway in ways that promote changes in brain functioning known to promote emotional well-being. The results of our first open trial have encouraged us to conduct a larger, more rigorous placebo-controlled, double blind study of WBH for MDD, which is currently underway at the University of Arizona Medical School. Missing from our assessments in this ongoing double-blind study is any measure of the impact of WBH on brain function. The current proposal addresses ths gap in our investigative portfolio by proposing to conduct a second, randomized trial of active vs. sham WBH that will examine the impact of WBH on measures of brain function known from prior studies to be important for both depression and its treatment.
In this Phase 4 trial we will study the safety, tolerability and efficacy of mixed salts amphetamine (MSA), trade name Adderall, augmentation of antidepressant therapy for Major Depressive Disorder (MDD) in depressed outpatient adults who are taking an antidepressant but have not had complete resolution of their symptoms.
The purpose of this study is to evaluate the safety and tolerability of escalating single oral doses of LY03005 in healthy subjects and to characterize the pharmacokinetics (PK) of escalating single oral doses of LY03005.
Perinatal depression is a common and serious mood disorder that increases morbidity and mortality in new mothers and results in poor infant/child outcomes. Current therapies often fail to produce recovery or are poorly tolerated and many pregnant women seek non-pharmacologic therapy or forgo treatment when non-pharmacologic options are not available. Expectant and new mothers who suffer from circadian rhythm disruption are at risk for perinatal depression. This R34 Pilot Effectiveness Studies and Services Research Grant seeks to test whether an Integrated Chronotherapy (IC) intervention can be implemented in an outpatient psychiatry setting to improve treatment outcomes for patients with perinatal depression. IC is a multicomponent treatment consisting of bright light therapy, sleep phase advance, and sleep stabilization/restriction that targets the Research Domain Criteria (RDoC) constructs of circadian rhythms, sleep-wake behavior, social rhythms, and arousal. We will assess the feasibility, safety, and acceptability of an IC intervention for perinatal depressin by testing the treatment in expectant mothers diagnosed with major depressive disorder during 3rd trimester of pregnancy. We will randomize patients to either: (a) usual care (UC, n = 20) or (b) IC+UC (n = 20). IC+UC will have pregnancy and postpartum components and will be administered via an individualized case formulation approach tailored to each patient. After a baseline assessment, IC will be prescribed during 5 dedicated clinical visits: three during 3rd trimester of pregnancy and 2 in the postpartum period. UC will consist of medication administered by a perinatal psychiatrist and/or psychotherapy. UC will be quantified in both groups to evaluate differences between the IC+UC and UC groups. Mood will be measured in both groups by blinded clinician interview and patient self-report. We will assess the safety profile of the IC intervention with evaluation of side effects/adverse events. Importantly, the study will also examine the putative mechanisms by which IC is hypothesized to work and the "dose" of IC received by patients in the IC+UC group. All participants will wear wrist actigraphy/light monitors continuously during weeks 28-40 of pregnancy and postpartum weeks 2-6 to assess light exposure and sleep duration and timing. Circadian phase (measured with salivary dim light melatonin onset) will be measured at baseline during pregnancy (~30 weeks gestation), at 36 weeks gestation, and at postpartum week 6. This pilot will allow us to refine the IC intervention for future integration into various clinical settings and establish an infrastructue for a larger (R01-scale) trial, including measuring acceptability of IC among UC clinicians and implementing web-based data collection to facilitate data sharing in the planned R01. Perinatal IC could have major public health impact due to the high prevalence of perinatal depression and its negative effects on mothers and their children. This project represents a first step toward achieving this goal, as it will provide the pilot data necessary to prepare for a larger scale intervention study focused on providing non-pharmacologic therapies and improving outcomes for women with perinatal depression.
Predictive factors and biomarkers of response to antidepressants in major depressive disorder are scarce. Beta-arrestins are proteins which inhibit G Protein Coupled Receptors and desensitize serotonergic and dopaminergic receptors. The study hypothesis is that Beta-arrestins 1 and 2 are predictive factors and biomarkers of response to antidepressants in major depressive disorder. In a controlled prospective open naturalistic monocentric 3-month study, 60 patients with a major depressive disorder requiring a treatment with venlafaxine will be included and assessed before treatment, 1 month and 3 months post-treatment. 20 controlled healthy subjects matched for age and gender will also be assessed. The Beta-arrestin pathway will be assessed using genetic polymorphisms, Peripheral Blood Mononuclear Cell measures and functional pathway. Antidepressant response will be assessed using depression scales, olfaction and memory as surrogate markers of neurogenesis.
The objective of the study is to examine whether a combination of wake therapy, light therapy and sleep time stabilization as a supplement to standard treatment can reduce depressive symptoms in patients admitted at two psychiatric wards at Aarhus University Hospital, Risskov. Seventy-four patients will be randomized either to this intervention or to a control group receiving treatment as usual. Furthermore, it will be examined whether the duration of admission can be reduced in the intervention group. Finally, the aim is to identify predictors of good effect of the intervention.
To evaluate the efficacy and the safety of ASC-01 (aripiprazole/sertraline combination) compared to sertraline monotherapy in patients with major depressive disorders who have responded incompletely to sertraline monotherapy.
Bupropion hydrochloride was first approved on 30 December 1985 in United States for depression and is currently approved in 80 countries. Bupropion has also subsequently been approved for smoking cessation and for seasonal affective disorder. Cumulative exposure to bupropion is estimated at approximately 97.3 million patient exposures up to 31 December 2012. Bupropion hydrochloride is a weak catecholamine reuptake inhibitor predominantly affecting serotonin, norepinephrine and dopamine. Its mechanism of action and its structural similarities to diethylpropion, amphetamines, and cocaine, bupropion resembles stimulants in many respects, leading to concerns about potential abuse of the product. Abuse potential had been part of the Benefit Risk Management Plan for bupropion up until 2003 and at that point, had no longer been regarded as a potential risk that required additional/further evaluation outside standard pharmacovigilance monitoring. The current European Risk Management Plan also states that standard pharmacovigilance monitoring applies to abuse potential. Monitoring has shown a recent increase in the number of spontaneous reports from the Adverse Event reporting System (AERS) of drug abuse. The bupropion team agreed that although the numbers of abuse reports was small relative to the total number of reports for bupropion in OCEANS, there was sufficient information in AERS to warrant investigation of the potential effect on public health. To investigate the degree of misuse and abuse of bupropion (including non-oral routes of administration) in the United States, the Drug Abuse Warning Network will be used to examine the study period 2004-2011.
