NCT ID: NCT01927276 Completed - Schizophrenia Clinical Trials

Randomized Controlled Trial of a Gluten Free Diet In Patients With Schizophrenia Who Are Gliadin-Positive

Start date: September 1, 2013
Phase: N/A
Study type: Interventional

Out of 300 million persons in the United States, about one-half of one percent, or 1.5 million, have a diagnosis of schizophrenia. Schizophrenia begins in young adulthood, and often is chronic and disabling for the remainder of the life course], which is shorter than for the general population by as much as 25 years. The costs of schizophrenia in the United States are estimated to be between $30 and $60 billion dollars annually. Treatment for schizophrenia is only marginally successful: in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE), for example, the medication prescribed at the beginning of the trial was stopped or changed in nearly 75% by the completion of the trial 18 months later. The medications have limited effect on negative symptoms or cognitive impairments of schizophrenia, and many have severe and permanent side effects. The basic hypothesis underlying treatment for schizophrenia has not changed for more than half a century. New treatments are needed. Much accumulating evidence suggests that sensitivity to gluten may be related to symptoms or etiology in schizophrenia and that gluten free diets may lead to significant symptom resolution, but only in patients who are known to have antibodies to gluten. Gluten sensitivity may be more common than thought and stems from a different etiology and symptom presentation than Celiac Disease. The investigators analysis of the CATIE sample show that about 23% of persons with schizophrenia (compared to 3% of healthy controls) have Gluten Sensitivity (about 300,000 persons in the United States) through the identification of gliadin positive antibodies in their blood. The investigators hypothesize that people with this biomarker could have robust symptom improvements with the removal of the antigen from the diet (gluten). If only half of people with schizophrenia and these antibodies were to substantially benefit from removal of gluten from the diet, as in the case studies and with certain subjects in the clinical trials, this would provide a new transformative treatment option for an identifiable subpopulation of people with schizophrenia and would be of enormous benefit to patients, families and society. Another benefit to the public's health from this study will be enhanced knowledge of the etiology of schizophrenia, including possible linkages between neuropsychiatric disease and immune system activation, and identification of novel, immune-linked treatment targets. The results of this research could lead to screening for Anti-Gliadin Antibodies early in life or at the first episode of schizophrenia, as recommended by some already. Screening involves financial and emotional costs, and better evidence is needed before this recommendation can be justified. Moreover, a new treatment paradigm of removing gluten from the diet by means of gluten blocking medications (already in early study) could advance treatment significantly. This study will test the efficacy, in a pilot fashion, of 20 participants in a double blind five week randomized placebo controlled gluten free diet vs identical diet with gluten in gliadin-positive individuals with schizophrenia. Approximately equal numbers will receive the addition of gluten, or non-gluten starch, in identical form (given as flour in food). The investigators plan to develop mechanisms and procedures to locate, screen, and recruit subjects into the inpatient intervention study, retain them during the inpatient phase. Once admitted baseline assessments may take approximately a few days but will be mostly completed in the first week prior to the 5 week randomization, thus patients may stay longer than 5 weeks. At the end of the double blind trial the investigators will prepare for discharge and then test the feasibility of successfully maintaining gluten free diets after the intervention phase is complete, for at least two months.

NCT ID: NCT01926912 Completed - Schizophrenia Clinical Trials

A Study of Usage of Paliperidone Palmitate in Patients With Schizophrenia in a Hospital Setting

HOSPIPalm
Start date: May 2013
Phase: Phase 4
Study type: Observational

The purpose of this study to evaluate safety, tolerability, treatment outcomes, appropriate use and pattern of paliperidone palmitate usage in participants with schizophrenia in the hospital setting.

NCT ID: NCT01926613 Completed - Schizophrenia Clinical Trials

Thinking Skills for Work in Severe Mental Illness

TSW
Start date: April 2006
Phase: N/A
Study type: Interventional

The purpose of this study is help people with serious mental illness and receiving vocational rehabilitation get and keep the job they want by improving their thinking skills, such as attention and memory, using computer exercises and other strategies. One half of the participants in the study will receive vocational rehabilitation and the exercises to improve thinking skills, and the other half will receive just vocational rehabilitation. All participants will receive an assessment of symptoms and thinking skills at the beginning of the study and 6, 12, and 24 months later. Work activity during the 24 months in the study will be collected. It is expected that those participants who receive the practice of their thinking skills will be more likely to get and keep the job they want compared with people who do not receive this treatment.

NCT ID: NCT01920685 Completed - Clinical trials for Paranoia in People With Schizophrenia-spectrum Diagnosis

Computerised Interventions for Thinking and Anxiety in Delusions (CITADEL) Trial

CITADEL
Start date: January 2014
Phase: N/A
Study type: Interventional

People with a schizophrenia spectrum diagnosis often experience distressing worries or beliefs about others intending to cause them harm (also known as paranoia). Paranoid beliefs are associated with significant distress and disruption to the person's life. This results in high use of services and costs to mental health providers. The National Institute of Clinical Excellence recommends that cognitive behavioural therapy for psychosis (CBTp) is offered to everybody with a schizophrenia spectrum psychosis. The latest meta analyses report improved outcomes, and reduced inpatient stays following CBTp, making it a cost effective intervention. Although improved outcomes have been obtained by therapies, CBTp has only small to moderate effects on paranoid beliefs. Further, training therapists to competently deliver CBTp is intensive, expensive and takes up to a year. CBTp is therefore not widely available to service users, resulting in inequalities in access to care. The investigators are seeking to improve outcomes and accessibility of CBTp for people with distressing, paranoid beliefs. The proposed research programme aims to conduct a feasibility study of a brief therapeutic intervention, aimed at targeting and improving anxiety processes that are causally implicated in paranoia (Freeman et al, 2015). The investigators have preliminary evidence indicating that the pilot intervention, with interactive multimedia content, reduced distressing beliefs and improved coping (Freeman et al, 2015). Participants also reported they found the therapy acceptable, enjoyable and useful. Based on these results, the investigators have further modified the intervention. The feasibility and efficacy of the therapy will be investigated in a randomised controlled design (n = 34). Please note the protocol has been been amended to exclude a pilot trial of a second brief intervention targeting reasoning styles in paranoia, as since the initial protocol was developed we have obtained data from two randomised pilot studies demonstrating its feasibility and acceptability (Garety et al, 2015; Waller et al, 2015). A further pilot trial of the reasoning styles intervention is therefore not indicated.

NCT ID: NCT01915017 Completed - Schizophrenia Clinical Trials

Interventions to Improve Functional Outcome and Persistent Symptoms in Schizophrenia

Mcog
Start date: April 2008
Phase: N/A
Study type: Interventional

Many individuals with schizophrenia continue to hear voices, have false beliefs, and problems with attention, memory planning and everyday functioning even with medication treatment. The process of recovery in schizophrenia involves treating the whole person. This study will test a new Multimodal Cognitive Treatment (Mcog). Mcog works around problems in attention, memory and planning by using supports in the home such as signs, checklists, and alarms to improve everyday functioning. Mcog also helps the individual to examine the evidence for their beliefs and to deal with symptoms like voices that are not completely resolved with medications. We will compare 4 treatments to determine if this combined approach improves both symptoms and functioning for individuals with schizophrenia.
