NCT ID: NCT02779205 Completed - Burns Clinical Trials

Child's Adipose Cells: Capacity of Tissue Regeneration

cicASChild
Start date: January 2012
Phase: N/A
Study type: Interventional

The beneficial effect related to the administration of adipose tissue-derived stromal cells (ADSC) is demonstrated in various situations of physiological and pathological wound healing, thus opening a new field for cell therapy. Despite the use of new technologies, management of burns in children as well as congenital malformation such as hypospadias and cleft lip and/ or cleft palate can lead to aesthetic and functional sequelae requiring multiple surgical procedures. Cell therapy based on the administration of the ADSC seems a promising issue in such indications, however, to date no study has been conducted with ADSC from a pediatric population. An initial study (Protocol 0808203) allowed investigors to obtain the first samples of adipose tissue from children and to conduct an in vitro comparative study on the characterization and properties of the ADSC from children compared to adults. In the continuity, this second study aims to complete knowledge on the efficacy and safety of children ADSC cell therapy assessed in an animal model of skin wound healing developed in the lab.

NCT ID: NCT02779179 Completed - Clinical trials for Rheumatoid Arthritis

Therapeutic Management of Periodontitis and Clinical Manifestations of Rheumatoid Arthritis

ESPERA
Start date: November 2010
Phase: N/A
Study type: Interventional

Although RA pathomechanisms remains incompletely understood, periodontitis and RA share pathogenic features : genetic and environmental influences, chronic inflammatory disease, immunoregulatory imbalance, bacterial factors, persistence of antigen/peptide and clinical factors (conjunctive and hard tissues destruction). Several hypothesis can be evocated : Gram negative bacterial systemic spreading, inflammatory transmitter substance systemic spreading (IL1, IL6, IL17, PGE2), systemic spreading of bacterial degradation products (LPS for example). Currently Porphyromonas gingivalis (PG) might be a susceptibility factor to RA because PG has an enzyme, the peptidylarginine deiminase leading to auto antibodies creation and RA increasing. As periodontitis, RA is chronic disease with a cyclic increase evolution, needing a complex pluridisciplinary treatment approach. Recent studies have reported an increased prevalence of RA patients with periodontal disease. Others studies show that periodontal treatment induces a significant decrease of the sedimentation rate and of the DAS28. Periodontitis is suspected to be an independent, aggravating factor in patients with RA (given the definition from NIH : an aggravating factor is something that makes a condition worse). So periodontal treatment cannot be considered as a RA treatment per se. But it is hypothesised that treating periodontitis in RA patients showing signs of periodontitis could result in improvement in RA disease activity. To date the role of periodontitis as an aggravating factor in these patients remains unclear, and only RCT designs can reasonably be used to test this causal hypothesis. There still remains some RA patients who have persistent symptoms and frequent exacerbations despite specialist care and continuous treatment, so results of treating aggravating factors are needed. As the majority of patients will benefit from a systematic evaluation and treatment of aggravating factors, the periodontal treatment strategy need to be tested. The aim of this randomised controlled trial is to assess the effectiveness of periodontal treatment for rheumatoid arthritis patients. To assess the effectiveness of periodontal treatment to reduce the severity of rheumatoid arthritis (RA), in patients suffering from both periodontitis and rheumatoid arthritis. The hypothesis is that periodontal treatment reduce the severity of rheumatoid arthritis.

NCT ID: NCT02778984 Completed - Anesthesia Clinical Trials

Facial Mask Tightness: A Comparative Study

A correct preoxygenation can be obtained after a 3min delay of calm ventilation through a tight mask thereafter mask is used to make the patient breathing before intubation. Most tight masks are actually sold but they have never been compared in studies. The aim of this study is to compare air leaks with standard facial mask and QuadraLite masks during preoxygenation and induction of anesthesia.

NCT ID: NCT02778828 Completed - Tuberculosis Clinical Trials

Pharmacokinetic and Therapeutic Adaptation of Linezolid in the Treatment of Multi-Resistant Tuberculosis

LINEZOLIDE
Start date: November 4, 2015
Phase: N/A
Study type: Interventional

Linezolid, primary treatment for MDR-TB combination therapy anti. Until it is the dose of 600 mg x1 / day, rather sensible for most patients is more, which was unanimous. It is true that if a dosage is consensus, it goes without saying, because of the interindividual variability, marked moreover to linezolid, a therapeutic monitoring assay of plasma levels is indispensable for most pharmacological treatments. This therapeutic drug monitoring (TDM) often gives rise, as known, to dosage changes. It turns out that at present no real STP on the basic objectives PK / PD is really made in France in the treatment of tuberculosis (TB) and the bibliography remains rather poor recommendations, and yet all the elements are there: indeed linezolid is an antibiotic whose activity is purely "time-dependent". So one should fulfill 2 PK / PD objectives whose precise boundaries are sometimes still to be determined: -% T> MIC, or percentage of time spent with plasma concentrations above the minimum inhibitory concentration of linezolid (LNZ) for Mycobacterium tuberculosis. In practice, the residual concentration before the next shot must be> MIC (0.125 to 1 mg / l) - A fortiori it must also take into account the concentration preventing the appearance of resistant mutants, amounting to 1.2 mg / l - AUC / MIC> 80, or ratio of the area under the curve (AUC, Area under curve) of plasma concentration versus time and CMI LNZ Until then, and without real bibliographic support, and for the sake of kindness to patients coupled with an economic advantage, the STP consisted of 2 samples, a peak 1:30 after taking (Cmax) and a residual before taking (C min) , after all, to 600mg x1 / 24 correlates well with the AUC (55% peak and 75% for the residual). Following an observation that 25 to 30% of patients had a C min <1.2 mg / L, and even frequently <0.2 mg / L to 600 mg x 1, with some low peaks and leaving presage an AUC may be insufficient well. This study is therefore more imperative to be a pharmacological streamlining and ensuring adequate therapeutic monitoring involves both maximum and minimum toxicity efficiency. And in the light of what has already been practiced for other molecules such as mycophenolate for example which is carried AUC or miniAUC for example. It would therefore be in the achievement of AUC in all patients treated with LNZ for TB MDR / XDR for over a week. Achieving this requires AUC obtaining 7 blood samples given day instead of two samples taken at present. Indeed one must have in mind that the peak of rational / residual has become blurred in this context, and that one of the two goals PK / PD is now filled (Cmin> MIC / CMP) but it should not be that not at the expense of the second (AUC). The benefits, direct and indirect are multiple and obtaining them is ensured through this protocol. The study by analyzing individual data will confirm the accuracy of the dose fractionation 300mgx2 / day and at a time to highlight a potential new dosage adjustment that would need to achieve for further study, so a substantial gain in terms of efficacy and toxicity via a suitable therapeutic monitoring. Secondly, determine which collection points, in these patients, these doses will be most interesting to take later in the routine of STP in order to collect less points (eg miniAUC MPA) retaining same statistical power to estimate kinetic parameters, mainly the AUC (eg aminoglycoside also). Finally in a third phase construction on the basis of these individual kinetics of a population pharmacokinetic model with highlighting of population parameters and especially co-related variables explaining the high pharmacokinetic variability and allowing for following patients to determine the individually tailored dose immediately before the first shot and the first assays.

NCT ID: NCT02778659 Completed - Physiology Clinical Trials

Hypnotic Intake and Motor and Cognitive Performances at High Altitude

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

This study aims to determine the effect of acute hypnotic intake (Zolpidem) on sleep, cognitive and motor performances and on acute mountain sickness symptoms at high altitude. Healthy subjects will be evaluated on 4 occasions (twice at sea level and twice at high altitude), after hypnotic or placebo intake. Following an early wake-up (01:00), symptoms, cognitive and motor performances will be assessed to determine potential residual effects of Zolpidem within such conditions.

NCT ID: NCT02778334 Completed - Cerebral Stroke Clinical Trials

Links Between Depression, Anxiety, Coping and Quality of Life After a Stroke

COPING
Start date: April 13, 2015
Phase: N/A
Study type: Interventional

Introduction and literature review With 130 000 cases per year in France in 2010, stroke is one of the most common neurological diseases, often leaving many disabling sequelae physical and cognitive levels (currently live 500 000 disabled following a stroke) and leading and a loss of significant autonomy in these patients. However, many stroke survivors soon find a range comparable to their previous state. Investigators can then ask ourselves about the impact of this life event in these people who apparently do not show visible effects: what about the psychological repercussions of stroke in these patients healthy; what is changed in their daily lives, particularly in their mental functioning after this brutal confrontation with their own mortality? Objectives Our project aims to better understand the psychological repercussions of stroke in patients who quickly find a health and autonomy comparable to their previous state. The objective will be to investigate the relationship between depressive symptoms and anxiety, coping strategies and quality of life from the acute phase and during the first months after the onset of stroke. This period is particularly demanding for these patients must therefore adapt and readjust continuously: shock stroke, hospitalization in several services (intensive care, neurology, rehabilitation), back home, "new" life with the changes related stroke, resumption of a professional activity, etc ... Our methodology will combine tools conventionally used (standardized interview, validated questionnaires) to newer, ecological and true methods (Experience Sampling Method applied by the use of a smarphone application) to assess different variables studied. This initially be determined whether the various symptoms of the depression on the one hand and anxiety on the other hand, depending on their mode of expression (vs. outsourced internalized; ie emotional, cognitive, somatic), observed from the acute phase of stroke, are related and predict the quality of life, depression and anxiety in the longer term (four months after the stroke). Furthermore, our study will observe if the individual coping strategies (coping) daily and evolution influence the psychological status and quality of life during the months following the stroke.

NCT ID: NCT02778321 Completed - Neuropathology Clinical Trials

Prospective Study Evaluating the Interest of Long-term Cardiac Recording in Cerebral Infarction

SPIDERFLASH
Start date: November 17, 2014
Phase: N/A
Study type: Interventional

Cerebral infarction (CI) can be linked to atherosclerosis of large vessels, occlusion of small vessels intracerebral (gaps), a cardioembolic disease or other rare causes. However, up to 40% of CI remains unexplained after a thorough diagnostic workup. They are called cryptogenic IC. Atrial fibrillation (AF) is the cause of 25% of the CI but it is recognized that episodes of paroxysmal AF, asymptomatic and unnoticed, may be responsible for a portion of the IC cryptogenic pace. Recognition of these episodes is of great importance since they have the same risk embolic the FA continues [1, 2] and motivate anticoagulant therapy startup. Several recording techniques heart rate were evaluated after the IC for detecting the AF. Their profitability increases with the duration of the recording: about 3% for a typical 24-hour Holter, the AF detection rate increases to 6% for a 7-day surveillance period, to 12-23% for 30 days and 17-26% with implantable recorders long. Otherwise brief rhythmic heart abnormalities can be detected with the waning of an CI without the significance of these episodes is known. Investigators decided to conduct this study because there is no prospective study of good quality with a sufficient number of patients that evaluated the interest of a non-invasive recording of long duration. The only randomized CRYSTAL AF is used for invasive subcutaneous implantable monitor (Reveal XT). To clarify the significance of arrhythmias and because the presence of several causes is common after 65, investigators propose to record all patients hospitalized for HF.

NCT ID: NCT02778178 Completed - Pain, Postoperative Clinical Trials

TAP Block Efficacy After Lumbar Spine Surgery Through Anterior Approach: a Randomized, Placebo-controlled Study

TAP-LIF
Start date: May 2, 2016
Phase: Phase 4
Study type: Interventional

Anterior Lumbar Interbody Fusion (ALIF) as well as Direct Lateral Interbody Fusion (DLIF) are established techniques for lumbar interbody fusion. In contrast with posterior approaches, they allow free approach to the anterior disc space without opening of the spinal canal or the neural foramina. However, the additional anterior approach conveys specific concerns, including abdominal pain that may delay recovery after surgery. The transversus abdominis plane (TAP) block is a validated approach for postoperative pain relief following abdominal surgeries. There is currently no evidence of the possible benefits of TAP block as part of multimodal pain management after ALIF/DLIF surgery. The investigator hypothesize that a single-injection TAP block reduces opioid consumption after anterior lumbar fusion surgery. The main goal of this prospective, randomized, double-blind, placebo-controlled study is to demonstrate a >35% reduction in opioid consumption during the 24h following ALIF/DLIF surgery.

NCT ID: NCT02777710 Completed - Colorectal Cancer Clinical Trials

Evaluation of Safety and Activity of an Anti-PDL1 Antibody (DURVALUMAB) Combined With CSF-1R TKI (PEXIDARTINIB) in Patients With Metastatic/Advanced Pancreatic or Colorectal Cancers

MEDIPLEX
Start date: June 2016
Phase: Phase 1
Study type: Interventional

Colorectal cancer (CRC) and pancreatic ductal adenocarcinoma (PDAC) are the most common gastrointestinal cancers in Western countries and are both associated with significant morbidity and mortality. An intriguing similarity between CRC and PDAC is the fact that the newly developed immune checkpoint inhibitors, especially PD1/PDL1 inhibitors, seem to have limited efficacy as single agents in both of these tumor types. Recent preclinical studies point towards alternatively activated (M2-type) macrophages as possible culprits in inducing local immune protection from cytotoxic T cells and resistance to PD1/PD-L1 targeted agents. We hypothesize that CSF1R blockade will deplete the tumor microenvironment of M2 macrophages, thus favoring the induction of a cytotoxic anti-tumor T-cell response following PD-L1 blockade with an anti-PD-L1 monoclonal antibody. So we propose to conduct a Phase I dose escalation study in order to evaluate the safety and clinical activity of a combined treatment associating an anti-CSF1R (PEXIDARTINIB) with an anti-PD-L1 (DURVALUMAB) in patients with advanced/metastatic colorectal or pancreatic cancers. Dose escalation part will determine the Maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of Pexidartinib given in combination with Durvalumab. Extension part will evaluate the clinical activity of the combination at the RP2D.
