Active clinical trials for "Syndrome"

The purpose of this study is to determine if testing patients for endothelial dysfunction will help identify which patients are more likely at risk to have another heart attack in the future. Study participants will undergo mental stress testing while at the same time being connected to a device that measures endothelial function via the Endopat device. These same participants will also undergo a sleep study via the Watchpat device.

This is a combination study to evaluate sapacitabine administered in alternating cycles with decitabine in previously untreated Acute Myeloid Leukemia (AML) or concomitantly with venetoclax in previously treated AML or MDS

The primary purpose of this study is to demonstrate the equivalence of the new Sleep Strip OTC(TM) compared to the reference method of an in-lab, attended full-night polysomnographic (PSG) study.

To characterize features of metabolic syndrome in volunteers. To undertake a randomised trial to determine whether treatment with a statin improves muscle microvascular blood flow.

The purpose of this clinical trial is to study the ability of a radioactive drug called "Technetium Glucarate" to detect whether the cause of chest pain in patients entering the emergency department with no obvious signs of heart attack is due to a condition called Acute Coronary Syndrome (ACS). The drug will be injected intravenously. After one or two hours the patient will undergo an imaging procedure to detect if the drug has accumulated in the heart. Uptake of the radioactive drug in the heart is indicative of reduced blood flow to the heart.

Visceral and somatic hypersensitivity as evidence of central sensory sensitization occur in the majority of Irritable Bowel Syndrome (IBS) patients. We recently demonstrated abnormal endogenous pain modulation as a cause of the sensitization in IBS and identified the underlying dysfunctional neuromatrix using functional MR-imaging (fMRI). Endogenous pain mechanisms regulate, fine-tune and integrate sensory and homeostatic, including neuroendocrine, immune and autonomic nervous system processes. Specific measures of sensitization and endogenous pain modulation correlate with clinical measures of somatic and neuropathic pain, suggesting usefulness as surrogate markers for clinical pain outcomes. Validation of experimental measures as surrogate markers in IBS would provide a considerable advance in pathophysiological and therapeutic research in this pharmacoeconomically burdensome disease.

The purpose of this study is to see if stress doses of hydrocortisone improve early outcome in patients who are in early stage of ARDS and with relative adrenal insufficiency.

The most frequent cutaneous T-cell lymphomas (CTCL) are mycosis fungoid and Sezary syndrome. The diagnosis of these lymphomas is difficult using current methods, especially because numerous benign dermatological conditions can mimick CTCL both clinically and under microscopic examination. Recently, the KIR receptor CD158k has been shown to be a marker for Sezary syndrome in both the blood and skin. We hypothesize that other receptors from the same family may help fro the diagnosis of these lymphomas. To address this issue, we will study the expression of all known KIR receptor in the skin of patients presenting with a skin eruption, which may correspond to either a cutaneous T-cell lymphoma or a benign dermatological disease. The final diagnosis will be established by a panel of experts, allowing constitution of 2 groups of patients : the cutaneous T-cell lymphoma group, and the benign inflammatory disease group. The expression of the different KIRs will be analyzed in both group in a blinded fashion, in order to determine whether one or a several KIRs may be differentially expressed.

The purpose of this study is to establish if a strategy of EBCPAP application in a subgroup of VLBWI, 800 to 1500g birthweight, decreases the need for mechanical ventilation in this group, without affecting mortality.

This study aims to evaluate the impact of nasal continuous positive airway pressure (nCPAP) treatment on liver enzymes in patients with sleep apnea syndrome and nonalcoholic steatohepatitis. Using a cross over design, the evolution of liver enzymes will be evaluated in 40 patients during a consecutive period of 6 weeks, with and without nCPAP treatment.
