Bromocriptine for Patients With Schizophrenia and Impaired Glucose Tolerance

This is a multicenter open-label, pilot study to evaluate the safety and tolerability of bromocriptine, a dopamine D2/D3 receptor and serotonin 5-HT2C receptor agonist, as an adjunct to preexisting standard-of-care antipsychotic drug (APD) regimens in the management of APD-associated impaired glucose tolerance (IGT)/insulin resistance (IR). The ultimate aim of the study team is to evaluate the efficacy of bromocriptine in treating the metabolic disturbances associated with APDs and the hypothesis is that bromocriptine will be a well-tolerated, safe, and inexpensive way to ameliorate these metabolic complications and prevent or delay the onset of type 2 diabetes (T2D). This study will be a small, short-duration pilot focusing on safety and tolerability. Twenty psychiatrically stable APD-treated outpatients, at two sites (VA Pittsburgh and Stanford), aged 18 to 60 years old, with schizophrenia and comorbid IGT will be recruited and receive 6 weeks of bromocriptine (flexibly titrated, 2.5-5.0 mg PO daily). Key inclusion criteria are: 1) currently being treated with second generation APDs for 3 or more months with no change in dose in the 1 month prior to enrollment, 2) fasting glucose 100 to 125mg/dL and/or hemoglobin A1c (HbA1c) 5.7-6.4%. Key exclusions are: 1) prior APD nonadherence, 2) drug/alcohol abuse in the 3 months prior to screening, 3) a history of violent behavior/psychoses, 4) pregnancy, or 5) a diagnosis of diabetes. Subjects on other dopamine agonists or on medications that may interact with bromocriptine and those taking corticosteroids or other medications that may alter glucose levels will be excluded. The purposes of the study are to demonstrate safety/tolerability, demonstrate feasibility, provide proof of concept, and provide an open-label assessment of the metabolic and psychiatric effects of bromocriptine in patients with schizophrenia treated with APDs. The primary metabolic outcome measures will be change in IR as measured by the HOMA-IR and change in IGT measured by HbA1c. Secondary metabolic outcome measures include body weight, fasting lipids, and prolactin. The specific aims are as follows: Specific aim 1: To establish the safety and tolerability of bromocriptine in patients with schizophrenia and IGT/IR treated with APDs. Specific aim 2: To demonstrate feasibility/proof of concept for an improvement in APD-induced IGT/IR with bromocriptine.

Peer-delivered and Technology-Assisted Integrated Illness Management and Recovery

Adults with serious mental illness (SMI) are disproportionately affected by medical comorbidity, earlier onset of disease, and 10 to 25 years reduced life expectancy compared to the general population. These high rates of morbidity and early mortality are associated with inadequately managed medical and psychiatric illnesses. A recent systematic review found nine effective self-management interventions that address medical and psychiatric illnesses in adults with SMI. However, there has been limited adoption of these interventions due to both provider and consumer-based factors. Provider-based barriers consist of the lack of an adequate workforce with the capacity, time, and knowledge of effective approaches to self-management support for adults with SMI and chronic health conditions. Consumer-based barriers associated with limited participation in self-management programs include lack of access, engagement, and ongoing community-based support for persons with SMI. Peer support specialists have the potential to address these barriers as they comprise one of the fastest growing sectors of the mental health workforce, have "lived experience" in self-management practices, and offer access to support in the community. However, challenges need to be resolved for peers to be effective providers of evidence-based interventions. For example, peers are frequently trained to provide "peer support" described as "giving and receiving help founded on key principles of respect, shared responsibility, and mutual agreement of what is helpful". Peer support has been associated with increased sense of control, ability to make changes, and decreased psychiatric symptoms. Despite benefits, peer support does not adhere to evidence-based practices for psychiatric and medical self-management and does not follow protocols that ensure fidelity and systematically monitor outcomes. The investigators hypothesize that mobile technology has the potential to overcome these limitations of peer support by providing real-time guidance in fidelity adherent delivery of a peer-delivered, technology-assisted evidence-based self-management intervention (PDTA-IIMR). The investigator will build the necessary expertise to pursue a career developing and testing novel approaches to peer-delivered evidence-based self-management interventions. Training will include: development of peer-delivered interventions; development and design of mobile health-supported interventions; and intervention clinical trials research. Concurrently, this study includes refinement of the intervention protocol with input from peers and consumers and conducting a pilot study evaluating the feasibility and potential effectiveness of PDTA-IIMR compared to routine peer support for N=6 peers and N=40 adults with SMI and chronic health conditions. Outcomes include feasibility, medical and psychiatric self-management skills, functional ability, and mortality risk factors and examine self-efficacy and social support as mechanisms on outcomes.

Feasibility Electrical Stimulation Study for Visual Hallucinations

The visual system has increasingly been recognized as an important site of injury in patients with schizophrenia and other psychoses. Visual system alterations manifest as visual perceptual aberrations, deficits in visual processing, and visual hallucinations. These visual symptoms are associated with worse symptoms, poorer outcome and resistance to treatment. A recent study using brain lesion mapping of visual hallucinations and identified a causal location in the part of the brain that processes visual information (visual cortex). The association between visual cortex activation and visual hallucinations suggests that this region could be targeted using noninvasive brain stimulation. Two case studies have found that brain stimulation to the visual cortex improved visual hallucinations in treatment resistant patients with psychosis. While promising it is unclear whether these symptom reductions resulted from activity changes in the visual cortex or not. Here we aim to answer the question whether noninvasive brain stimulation when optimally targeted to the visual cortex can improve brain activity, visual processing and visual hallucinations. The knowledge gained from this study will contribute to the field of vision by providing a marker for clinical response and by personalizing treatment for patients with psychosis suffering from visual symptoms. This grant will allow us to set the foundation for a larger more targeted study utilizing noninvasive brain stimulation to improve visual symptoms in patients with psychosis.

Study of the Impact on the Therapeutic Alliance of a Short Initial Psychoeducation Programme in Patients With Early Schizophrenia

Schizophrenia is a serious, disabling and unfortunately common disease. Its prevalence is in the order of 0.6 to 1% in the general population, a figure that remains relatively stable in the various cultures. The overall prognosis, particularly in terms of function, remains largely negative. We know that a global management can considerably slow down this unfavourable evolution: according to the recommendations, the patient suffering from schizophrenia requires an effective and well-tolerated pharmacotherapy, associated with an adapted psychotherapy as well as cognitive remediation workshops, training in social skills, and psycho-education. There are indeed a large number of studies that have shown these elements in patients with schizophrenic disorders that have been present for several years. We now know that early treatment is a key prognostic element. Indeed, the earlier care is provided during the first psychotic episode, the better the subsequent prognosis: the probability of further decompensation is reduced, as is the risk of developing deficits, such as cognitive difficulties. However, there is a lack of access to all the recommended aspects of management in the initial phase of the disorder, particularly concerning early psycho-educational programmes for patients, which have been relatively little studied in clinical research. In this context, it seems relevant to study the impact of a new programme of this type on a fundamental parameter, conditioning the subsequent access to care: the therapeutic alliance. "PPIC" is a short psycho-educational programme in 4 sessions, specifically designed to accompany young patients, and focused on the issues of this crucial period of the care process.

Efficacy and Mechanisms of Transcranial Direct Current Stimulation (tDCS) - Effects on Working Memory in Schizophrenia

Impairments of cognition are a core, severely disabling feature of schizophrenia leading to poor long-term outcome with no established treatment available. Particularly impaired executive functions (e.g working memory) are frequently observed and are consistently associated with reduced activation of the dorsolateral prefrontal cortex (dlPFC). Deficits in those functions have been shown to be closely related to negative symptoms, thought disorder, and functional outcome in schizophrenia leading to the notion that frontal lobe dysfunction is crucially important in schizophrenic psychopathology. Noninvasive brain stimulation like tDCS can enhance executive functions like working memory in healthy subjects as well as in patients. To identify the optimal parameters for this intervention in patients with schizophrenia, the investigators first test the effects of different polarities (anodal, cathodal), stimulation intensities (1mA, 2mA) and laterality (left, right) on working-memory performance (nback task) in a sham-controlled cross-over design (n=128). To elucidate mechanisms of action, oscillatory brain activity will be registered with electroencephalography (EEG). These experiments will provide reliable data for an evidence-based development of new clinical interventions to improve treatment of cognitive deficits in patients with schizophrenia and thus enhance schizophrenia prevention and recovery.

Targeting Physical Health in Schizophrenia: Physical Activity Can Enhance Life Randomized Control Trial

Purpose: To test the effectiveness of an exercise intervention that combines group walking, activity tracking, and heart rate monitoring (i.e. Physical Activity can Enhance Life, PACE-Life) on the physical and mental health for individuals with schizophrenia spectrum disorder. Participants: 56 individuals with schizophrenia spectrum disorders. Procedures (methods): During the baseline assessment, which can be completed virtually and in-person (based on participant preference) all participants will be provided with a Fitbit wristband and instructed how to use it. During the first group session, participants will be taught how to use their heart rate (on the Fitbit) to determine how fast participants should walk (to achieve the appropriate exercise dosage). Information on proper care, usage, and how to determine the appropriate heart rate from the watch, to guide the intensity of the walk, will be provided to participants and reviewed at each group session. Participants randomly assigned to the PACE Life virtual walking group sessions will meet the other group members and group leaders and be reminded of the heart rate (HR) that corresponds with the intensity of that group session. Next, the group will exercise for 15 minutes in the first two weeks, progressing to 30-minute walking sessions over the course of the intervention. At the completion of the sessions, everyone will take a break for water and review the walk. After the second group session of each week, participants will receive weekly progress reports of their steps and minutes spent walking the prior week (obtained from Fitbit devices). During this session, participants will also set individual goals for the upcoming week for both their "intensity walks" and total steps per day. Participants randomly assigned to Fitbit Alone will be given a Fitbit and shown how to use it by study staff. Participants will also be given information on current recommended physical activity guidelines (150 min/week of moderate intensity exercise) and will be told that study staff may be contacting them on a weekly basis (or shorter, if necessary) if it looks like participants are not wearing their Fitbit for a certain number of days (e.g. 3 consecutive days) or to troubleshoot any issues. If necessary, participants might be invited to meet with research staff to get assistance on any Fitibit or exercise-related issues.
