Active clinical trials for "Syndrome"

The purpose of this research study is to determine which measures best capture cardiovascular disease (CVD) risk and type 2 diabetes (T2DM) risk in children and adolescents with Down syndrome (DS). We hypothesize that DS is associated with worse cardiometabolic risk factors for a given body mass index compared to controls. This difference arises at least in part, from increased fat tissue.

Purpose: To evaluate morphological and functional characteristics of Irvine Gass syndrome Methods: 30 patients suffering on Cystoid macular edema (CME) secondary to Cataract surgery will be observed and evaluated by fluorescein-angiography, SD-OCT, reading performance, contrast sensitivity and microperimetry in a fixed time schedule

The purpose of this study is to evaluate the ability of a non-invasive monitor that measures how much fluid is in the body as well as various blood tests for their ability to predict worsening kidney function in patients with heart failure.

Coronary angioplasty is rather frequently performed in such situations, presumably because, changes in the atherosclerotic plaque under drug treatment, have remained poorly described so far. Intravascular ultrasound (IVUS) enables a precise description of coronary atheroma, better than the one provided by coronary angiography.

There is limited published clinical data about the natural history of renal disease in Alport syndrome. The RG012-01 study will collect data to characterize the progression of renal dysfunction in Alport syndrome patients. Patients with a confirmed diagnosis of Alport syndrome who have qualifying GFR will be considered for enrollment. The sequential sampling of subjects' urine and/or blood will allow an assessment of the rate of change of established clinical endpoints, such as GFR and/or the rate of change of other renal biomarkers (proteinuria and β-2 microglobulin) in subjects whose renal function is steadily declining. The identification of surrogate markers that track the decline of renal function and could correlate with time to end-stage renal disease (ESRD) is a key goal of the natural history study.

The main objective of the project is to assess the long-term prognostic impact of residual platelet reactivity after optimal antiplatelet therapy in a large cohort of patients with acute coronary syndrome undergoing invasive strategy. Follow-up length will be at least 24 months. The primary end-point of the study will be a composite of death, myocardial infarction, urgent target vessel revascularization, stent thrombosis or stroke.

Congenital central hypoventilation syndrome (CCHS) is a rare disorder of respiratory control characterized by ventilatory impairment that results in arterial hypoxemia. Although patients typically present this disease as newborns and rarely in later infancy, there have been reports of patients presenting with CCHS in adulthood. The present study reports a unique familial case in which the father (proband) presented late-onset CCHS with an expansion mutation of the Phox2B gene that was confirmed by genetic analysis. Surprisingly, the proband did not report any manifestation of the disease during childhood, and the disease progressed following an insidious course until adulthood. At the time of diagnosis, he did not present signs of pulmonary hypertension and right-side heart failure. The patient responded well to nocturnal invasive ventilation. In contrast, his son presented CCHS as a newborn with the full complement of symptoms while his daughter did not. The present report shows that CCHS cases characterized by a mutated Phox2 gene can progress without many symptoms and that the treatment approach used here was efficient for controlling the course of the disease. Furthermore, this case indicates that incomplete penetrance can occur. Genetic screening of family members is mandatory to evaluate the reproductive risk of the disease, especially because asymptomatic mutation carriers may be at high risk to develop the disease and transmit it to the next generation.

The purpose of this study is to determine if submaximal exercise by bicycle stress tests with pulmonary measurement of VO2MAX plus maximal isometric hand grips on 2 consecutive days causes a higher level of "exertional exhaustion" in GWI compared to healthy veterans (HVets).

The purpose of this study is to understand what causes a continuing fatigue for a long time with a number of symptoms occurring at the same time (Chronic Fatigue Syndrome-CFS). Epstein Barr Virus is among the group of viruses that have been associated with a continuing fatigue for a long time with a number of symptoms occurring at the same time, but the cause is still unknown.

The Control Study for the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network has been established to focus on a broader approach to the study of Interstitial Cystitis (IC)/Painful Bladder Syndrome (PBS) in men and women, and Chronic Prostatitis (CP)/Chronic Pelvic Pain Syndrome (CPPS) in men, than previously undertaken. Participants with no Urologic Pelvic Pain Syndromes as well as participants with specific conditions (Fibromyalgia (FM), Irritable Bowel Syndrome (IBS), Chronic Fatigue Syndrome (CFS)) are being recruited for the Trans-MAPP Control Study. These participants will act as a reference/control group for the Trans-MAPP Epidemiology & Phenotyping (EP) Study. As with many chronic pain disorders, IC and CP are poorly understood, and treatment is often not helpful. The goal of this study is to better understand how pain is felt in people with IC or CP. The MAPP Control Study is an observational study that will enroll participants from 6 Discovery Sites and 3 Satellite Sites across the U.S. The investigators will ask questions and gather information about the health and life of the participants for research purposes. The investigators hope that this study will lead to improvement in the treatment of IC and CP.
