NCT ID: NCT01066208 Recruiting - Clinical trials for Giant Cell Arteritis

American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) Diagnostic and Classification Criteria for Primary Systemic Vasculitis

DCVAS
Start date: January 2011
Phase: N/A
Study type: Observational

Vasculitis is group of diseases where inflammation of blood vessels is the common feature. Patients typically present with fever, fatigue, weakness and muscle and joint aches. These symptoms are very common among many different diseases, not just vasculitis. A clustering of other symptoms, physical examination findings, blood tests, radiology and biopsy help make the diagnosis. There are currently no criteria to help doctors make a diagnosis of vasculitis when a patient presents with these non specific symptoms and they are reliant on previous experience and disease definitions. One of the aims of this project is to develop diagnostic criteria for the primary systemic vasculitides (granulomatosis with polyangiitis (Wegener's), microscopic polyangiitis, Churg Strauss syndrome, polyarteritis nodosa, giant cell arteritis, Takayasu arteritis). We, the investigators, will do this by studying a large group of patients with vasculitis and comparing them to a large group of patients that present in a similar way, but do not have vasculitis. By comparing the 2 groups we will create a list of items to differentiate between vasculitis and 'vasculitis mimics'. We also aim to update the current classification criteria. Classification criteria are used to group patients into different types of vasculitis, once a diagnosis of vasculitis has been made, and are useful for studying patients in clinical trials with similar or identical diseases. The current classification criteria (American college of Rheumatology 1990 criteria) were developed 20 years ago, before the availability of some important diagnostic tests (e.g. antineutrophil cytoplasmic antibodies [ANCA]), and are now not consistent with some of the current disease definitions. Therefore to progress future research in vasculitis, it is important that the classification criteria are updated. We will recruit 260 patients with each of the 6 types of vasculitis and compare them with 1300 controls (patients with the 5 other types of vasculitis), in order to determine the optimal combination of symptoms, signs and investigations that classify each person into the appropriate group.

NCT ID: NCT01046448 Recruiting - Clinical trials for Cardiovascular Disease

The Cardiovascular Comorbidity in Children With Chronic Kidney Disease Study

4C
Start date: July 2009
Phase: N/A
Study type: Observational

Children and adolescents with chronic kidney disease (CKD) are at high risk for cardiovascular (CV) morbidity and mortality. Recent studies suggest that pediatric patients with even moderately impaired kidney function may be afflicted with significant early cardiac and vascular abnormalities. The pathogenesis and the natural course of CV comorbidity in pediatric CKD patients is still elusive. In this multicenter, prospective, observational study the prevalence, degree and progression of CV comorbidity in children will be characterized and related to CKD progression. The morphology and function of the heart and vessels will be monitored by sensitive, non-invasive methods and will be compared with aged matched healthy controls. Multiple potential clinical, anthropometric, biochemical, and pharmacological risk factors will be monitored prospectively and will be related to CV status. Genotyping might identify predisposing genetic factors for progression of CV comorbidity and underlying nephropathies.

NCT ID: NCT00994799 Recruiting - Macular Edema Clinical Trials

NCT ID: NCT00949195 Recruiting - Healthy Subjects Clinical Trials

Pulmonary Arterial Pressure Response During Exercise

PAPCOPDHS
Start date: September 2009
Phase: N/A
Study type: Observational

Background: The extent of increase in systolic pulmonary arterial pressure (PAPs) during exercise in patients with COPD is unpredictable from lung function data. The non-invasive assessment of pulmonary hemodynamics during exercise and flow-mediated vasodilatation measurement may give useful data in the rehabilitation of COPD patients. Methods: Patients with stable, severe COPD and healthy, age-matched subjects (H) perform semi supine echocardiography with PAPs measurement. COPD patients perform ramp protocol with gas exchange detection. Serum hsCRP level is also determined in COPD patients. Endothel dysfunction is detected by flow mediated vasodilation measurement after arm strangulation with Doppler ultrasonography. Primary endpoint: The degree of pulmonary artery systolic pressure change during exercise? Secondary endpoint: 1. The degree of right ventricular function change during exercise? 2. Is endothel dysfunction manifested with pulmonary artery pressure rise? 3. What is the correlation between the systemic inflammatory marker hsCRP and the degree of pulmonary artery pressure rise?

NCT ID: NCT00883402 Recruiting - Carotid Stenosis Clinical Trials

Carotid Endarterectomy Versus Carotid Artery Stenting in Asymptomatic Patients

ACST-2
Start date: January 2008
Phase: N/A
Study type: Interventional

The trial randomise patients with asymptomatic carotid artery narrowing in whom prompt physical intervention is thought to be needed, but there there is still substantial uncertainty shared by patient and doctor about whether surgery or stenting is the more appropriate choice. The study is looking at immediate risks (within one month)and at long term benefits

NCT ID: NCT00358943 Recruiting - Gaucher Disease Clinical Trials

International Collaborative Gaucher Group (ICGG) Gaucher Disease Registry & Pregnancy Sub-registry

Start date: April 1, 1991
Phase:
Study type: Observational [Patient Registry]

The ICGG Gaucher Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Gaucher disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Gaucher disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Gaucher medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Gaucher disease population. - To evaluate the long-term effectiveness of imiglucerase and of eliglustat. Gaucher Pregnancy Sub-registry: The primary objective of this Sub-registry is to track pregnancy outcomes, including complications and infant growth, in all women with Gaucher disease during pregnancy, regardless of whether they receive disease-specific therapy. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician.If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.
