Active clinical trials for "Syndrome"

The acute respiratory distress syndrome (ARDS) is an important cause of acute respiratory failure with a high mortality rate. The mechanism of resolution of the late organizing phase remains uncertain. The ACE gene contains a polymorphism based on the presence (insertion, I) or absence (deletion, D) within an intron of a 287-bp nonsense DNA domain, resulting in three genotypes (DD and II homozygotes, and ID heterozygotes). It has been shown that I/D polymorphism of ACE gene may account for half the variance of serum ACE levels in the Caucasians. Polymorphism of the ACE gene has also been shown to contribute to the development of some respiratory diseases. We hypothesize that the presence of ACE gene polymorphism can affect the outcome of ARDS. The objective of this proposed study is to determine the genotypes of ACE gene polymorphism and assess the influence of ACE genotype on the outcome and pulmonary resolution of patients with ARDS. Patients diagnosed to have ARDS are eligible for possible inclusion into the study. The ACE genotype of all patients with ARDS will be determined by polymerase chain reaction (PCR) amplification of the respective fragment for the D and I alleles from intron 16 of the ACE gene and size fractionation by electrophoresis. The outcome of patients with ARDS in the three genotypes will be compared.

This is a natural history study of Alpers Huttenlocher Syndrome. Patients will be followed over time to assess clinical symptoms for the purpose of expanding knowledge of this disorder in the medical community.

Hypothesis: to address if diagnosis of obstructive sleep apnea before or during the extending check-up is a risk factor toward metastasis for melanoma stage ≥ tIIaN0M0 Study design: Adult patients with a Breslow's Thickness ≥ 1mm coming to the surgery consultation will have a nocturnal oximetry for screening of obstructive sleep apnea. Patients having an abnormal nocturnal oximetry will be explored by polysomnography in order to detect sleep apnea syndrome. Patients with sleep apnea will be treated. Standard dermatologic follow-up over a 3 years period with thoraco-abdominal-pelvic and cerebral CT-scan and a lymph-node ultrasound every 6 months will be performed.

This was a prospective, open-label study with no participant randomization. Treatment for aHUS was observational and at the discretion of the treating physician. The purpose of this study was to assess disease manifestations of complement-mediated thrombotic microangiopathy (TMA) and evaluate potential clinical predictors of disease manifestations and progression in participants with aHUS with or without eculizumab treatment in the clinical setting.

Thoracic outlet syndrome may associate neurologic, arterial and venous symptoms. The responsibility of repetitive movements and postural factors has been mentioned for long. Some tasks are hard to perform, and it seemed interesting to assess the consequences of this syndrome on the work capacity by a questionnaire, at the moment of diagnosis by Echo-Doppler

Coronavirus Disease 2019 (COVID-19) (previously called 2019-nCOV acute respiratory disease) is caused by SARS-CoV-2, a positive-sense single-stranded RNA virus of the coronavirus family. The coronaviruses are largely responsible for the common cold, the 2002 SARS outbreak in Guangdong, China, the 2012 MERS outbreak in Saudi Arabia, and the present COVID-19 outbreak that originated in Wuhan, China. Much has been reported by way of systemic injury caused by COVID-19 affecting the cardiovascular, hepatic, nervous systems. These conditions are likely the result of the virus overwhelming the immune system. For these reasons, the investigators wish to conduct this study using existing medications off-label, and over-the-counter supplements to support the immune response, prevent lasting injury, and hasten the recovery from COVID-19.

Acute respiratory distress syndrome (ARDS) is a devastating form of acute lung inflammation, that may be caused by a variety of insults with pulmonary and systemic infectious disease being the most common predisposing factor. Sepsis, on the other hand, represents the systemic inflammatory response to an invading pathogen, which may inflict damage upon the host through organ dysfunction. ARDS and sepsis are heterogenous clinical conditions that have a high mortality, and both diseases involve a complex interplay of different inflammatory mediators and cell types. It has been suggested that locally released inflammatory mediators pass from the lungs into the bloodstream following ARDS, triggering systemic inflammation. Conversely, it is possible that severe systemic inflammation may lead to ARDS by an influx of inflammatory mediators from the bloodstream to the lungs. However, the time course and the possible pathways for this transmission of disease have yet to be established. Investigators hypothesize that: Primary systemic inflammation is followed by a secondary pulmonary inflammatory response Primary pulmonary inflammation is followed by a secondary systemic inflammatory response Both primary and secondary inflammatory responses are characterized by the appearance of pro-inflammatory cytokines, inflammatory cells and production of collagen-like proteins (termed 'lectins') The inflammatory response is most pronounced in the primary afflicted compartment.

To study compliance with secondary prevention during the first months following discharge from the cardiac intensive care unit (CIC) of patients experiencing a first episode of acute coronary syndrome : quantitative compliance over 3 months with the two principal treatments of the prescription (a statin - rosuvastatin, Crestor® and a platelet aggregation inhibitor - clopidogrel, Plavix®), using an electronic measure system ("intelligent blister" pack®);

This multicenter, multinational, longitudinal study will quantify endurance and respiratory function in subjects diagnosed with MPS IVA and will better characterize the spectrum of symptoms and biochemical abnormalities in MPS IVA disease over time.

The aim of this study is to evaluate the role of cognitive disorders and quality of life in patients with CIS, considered as high risk to develop an MS, treated with interferon Beta. This prospective observational study will include 120 patients, all treated and evaluated annually with neurological extensive examination, ophthalmologic screening (OCT, OF, VEP, VF), auto questionnaire about fatigue (musicol, ELIF), quality of life (SEP-59), and conventional MRI.
