NCT ID: NCT02754375 Recruiting - Depression Clinical Trials

SMTr-METAB : FDG-PET Assessment of Cerebral Metabolism in Resistant Depression Treated With rTMS

Start date: May 2016
Phase: N/A
Study type: Interventional

Biological markers of depressive states have been studied, but their usefulness to predict the therapeutic response is unknown. This issue is major in all depressive states which have not remitted after several lines of treatment. rTMS (repetitive transcranial magnetic stimulation) is a non-pharmacological alternative in the treatment of depression, but its effects on cerebral functioning are not known in episodes which have resist to conventional treatments. The investigators will include 50 depressive patients who have failed to respond to two successive antidepressant medication, and propose them a treatment with low frequency rTMS during 3 to 6 weeks. Cerebral functional imaging with 18FDG-PET (positon emission tomography) with be assessed at the beginning and at the end of rTMS acute treatment, in order to measure induced metabolic changes and their correlation with clinical states. Patients who have responded to rTMS acute treatment may continue this therapeutic for six months, and the investigators will assess if efficacy maintenance is related with cerebral metabolic variations

NCT ID: NCT02744989 Recruiting - Schizophrenia Clinical Trials

STIM'ZO : Examining tDCS as an add-on Treatment for Persistent Symptoms in Schizophrenia

Start date: June 2016
Phase: N/A
Study type: Interventional

This project aims to provide the proof of concept for transcranial direct-current stimulation (tDCS) in the treatment of resistant/persistent Schizophrenia symptoms. The purpose is to investigate the effect of tDCS on symptoms in schizophrenic patients demonstrating a partial response to a first frequently prescribed antipsychotic medication. An early optimization of the therapeutic strategy must constitute an important factor for prognosis. Hypothesize is that tDCS should alleviate symptoms in patients depending on the clinical characteristics. In this study, stimulation is an add-on treatment to antipsychotic medication, and will be used in a broad variety of patients, i.e. in patients with varied durations of illness, various symptoms profiles, and various levels of treatment response. This in turn will allow the determination of the extent to which results can be generalized to varied patient populations, as well as the extent to which various therapeutic targets (e.g. different symptom dimensions, cognitive performance and brain connectivity) may be improved with tDCS. Despite interesting preliminary results, our team is unable to describe optimal non-invasive brain stimulation (NIBS) response markers. This study is a randomized, double blind, controlled, French multicenter study (11 centers). The investigators plan to include 138 patients with persistent symptoms in schizophrenia. Sixty-nine subjects will receive active tDCS and 69 subjects will receive sham tDCS (placebo). Hypothesize is a lasting effect of active tDCS on the schizophrenic symptoms as measured by the number of responders, defined as a decrease of at least 25% of symptoms as measured by a standardized clinical scale score (PANSS) between baseline and after the 10-session tDCS regimen. Furthermore, the participants believe that an in depth understanding of the cortical effects of tDCS could constitute an important step towards improving the technique and developing treatment response markers. An analysis of the effects on cortical activity and plasticity markers could be an interesting approach.

NCT ID: NCT02689622 Recruiting - Clinical trials for Myelodysplastic Syndromes

PREDICTive FactOR of Overall Survival Among Geriatric Assessment Tools and Disease Related Factors in Elderly Patients With High Risk Myelodysplastic Syndromes.

Start date: April 2016
Phase: N/A
Study type: Interventional

No prospective study was conducted in elderly patients with cancer to assess the relative value of disease-related and patient-related prognosis factors. Patient-related prognostic factors have been highlighted in elderly patients with cancer resulting in the necessity of a geriatric assessment. The impact on overall survival of all of these factors was recognized in elderly people with cancer but remains unknown in High Risk Myelodysplastic Syndromes (HR-MDS). Therefore this information could be crucial to better select geriatric assessment domains relevant for the prediction and to recommend simplified tool after stratification of geriatric assessment domains thanks to their predictive value. The main hypothesis is that patient-related factors will have a better capacity to predict survival and treatment tolerance than disease-related factors in HR-MDS aged 75 and over and that the predictive value will be different among assessment tools which allows a selection of reduced number of tools for clinical use. To best knowledge estimation of predictive value of geriatric assessment tools remains unknown and explains why no standardization of practice exists. In testing all tools at the same cohort of patients allows to compare different tools and to define minimal and optimal geriatric assessment for HR-MDS. To determine the best strategy of geriatric assessment will allow in a second time to measure the impact of the use of this geriatric standardized evaluation by comparing patients'care and prognosis according to the use or not by the doctors of the new scores. Research outcomes are various medical, economic and ethic. Medical because decision-making will be improved with simplified geriatric assessment; economic because a better knowledge of geriatric assessment will improve treatment toxicity prevention and decrease treatment costs. Ethic will be associated with this project because a better knowledge of geriatric assessment tools to predict survival and tolerance treatment could improve the choice of best supportive care if prognosis markers are not favorable to active therapy. This project could induce important modification of practice in this area to an improved personalized treatment and simplification of geriatric assessment allowing a large diffusion in hospitals and clinics.

NCT ID: NCT02547493 Recruiting - Clinical trials for Rheumatoid Arthritis

Vaccination Against Pneumococcal in Naïve Abatacept Rheumatoid Arthritis Patients

Start date: September 2015
Phase: N/A
Study type: Interventional

Is pneumococcal conjugate vaccine (which induces a T-dependent humoral response) more efficient than pneumococcal polysaccharide vaccine (which induces a T-independent humoral response) in RA patients treated with abatacept, biotherapy targeting T-cells? The investigator propose to conduct a prospective, multicenter (11 centers), randomized, open-label study. The patients are going to be randomized in 2 groups: patients of the first group will be vaccinated with the polysaccharide pneumococcal vaccine (Pneumo23®) whereas patients of the second group will be vaccinated with conjugate pneumococcal vaccine (Prevenar13®).

NCT ID: NCT01899365 Active, not recruiting - Clinical trials for Pneumococcal Infections

An Incitative Multifaceted PROcedure for Pneumococcal Vaccination at the Emergency Department

Start date: November 2015
Phase: N/A
Study type: Observational

Background : Community-acquired pneumonia (CAP) is a threat in industrialized countries. It represents the 6th cause of death. CAP also frequently associates with other disorders responsible for admission and death. Among bacteria responsible for CAP, Streptococcus pneumonia is a major pathogen that is commonly involved and frequently leads to severe infection and admission. Categories at risk for this pathogen have been determined, and can be proposed anti-pneumococcal vaccination (APV) that efficiently and safely protects from this microorganism. In the context of US health services, monocenter pilot experiences have reported improvement of pneumococcal prophylaxis implementing vaccination procedure at ED. A study that set in New Mexico (2003) reported a significant increase in APV (from 18% to 84%) when patients at risk were proposed vaccination at ED. To obtain these results, medical students were specifically trained and dedicated to screen and vaccinate against St. pneumoniae. Another single center trial (Tennessee, 2007) for APV at ED obtained an improvement (from 38.8 to 45.4%) when physicians were alerted for pneumococcal risk by the software they usually utilized at bedside. However these experiences remain sparse as additional dedicated resources are required or patients and attending ED physicians can be reluctant to proceed to vaccination at ED. Mobile phone and derived communication modalities are current vectors to deliver information in several fields including education and medicine. Initially used in developing countries, short-message services (SMS) have improved behaviour of patients in various medical areas. In France, the investigators have observed that most patients above 50 years of age admitted after ED visit are equipped with mobile phone and can receive alerts by SMS. These observations prompt us to propose a multifaceted procedure to improve APV after ED visit in at-risk patients, combining structured oral interview, written information and SMS as reminders. Purpose : The investigators hypothesized that - a multifaceted intervention to promote anti-pneumococcal vaccination combining a structured oral interview, a written information to patient and his/her general practitioner, and a series of 3 SMS, - improves anti-pneumococcal vaccination at 6 months, - in at-risk patients (65+ years) visiting the emergency department. In order to answer this question, the investigators designed an interventional prospective multicenter randomized study (cluster).
