Filter by:Exploratory study of anti-pneumococcal immune response in patients with Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) immunized according to new vaccine recommendations (i.e. with a combined vaccine schedule (13-valent conjugate pneumococcal vaccine -PCV13- followed by a 23-valent non-conjugate pneumococcal vaccine -PPV23- 8 weeks later).
Descriptive study of the residual anti-pneumococcal immunity in patients with Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) who have previously gone through pneumococcal immunization.
Rare diseases frequently affect women of childbearing age. Pregnancy in these women has become less rare, but remains associated with high levels of complications. One obstacle to their optimal management during pregnancy is that there are no prospective studies of pregnancy during rare diseases and several connective tissue diseases. As a consequence, the management of these pregnancies is non-standardised in terms of treatment, monitoring (frequency of consultations, laboratory tests and ultrasound), and organisation of care. Moreover, although these women (all diseases combined) are frequently exposed to medications potentially incompatible with pregnancy, little is known about the frequency of these exposures and especially their consequences to mother and child. For these reasons, researchers and clinicians from different specialties created an interdisciplinary research group on pregnancy and rare diseases (GR2), intended to improve the management of these patients' pregnancies. Using a single computer server, the investigators plan to set up a large prospective study of pregnancies in patients with rare diseases: various forms of myositis, lupus, antiphospholipid syndrome, Sjogren syndrome, scleroderma, and inflammatory rheumatic diseases. The investigators objective is to analyse the complications of pregnancies in women with rare diseases and then to improve their management and their quality of life.
MAINRITSAN study compared Rituximab and azathioprine as maintenance therapy for ANCA-associated vasculitides. In this study, Rituximab (5 infusions at D1, D15, M6, M12, M18) was superior to azathioprine (2 mg/kg/day) to prevent relapses of AAV 28 months after the inclusion (Guillevin et al. NEJM 2014). Nevertheless, in the follow-up study of MAINRITSAN, up to 30% of patients experienced a relapse 38 months after the last rituximab infusion (unpublished data). Right now, no randomized controlled study has been carried in order to evaluate the best duration of the maintenance treatment with rituximab. The investigators objective is to evaluate the efficacy of a long term rituximab treatment to prevent relapses of ANCA-associated vasculitis in patients in remission after a first phase of rituximab maintenance treatment. The investigators will conduct a randomized placebo-controlled trial of a long term rituximab maintenance treatment (46 months) against a conventional maintenance treatment (18 months).
The purpose of this study is to evaluate denosumab as a novel treatment for bone loss in children treated with glucocorticoids for rheumatic disorders. This is a pilot Phase 1/2, randomized open-label, 12-month clinical trial of denosumab to assess its effect on bone resorption markers and bone mineral density (BMD) in children with rheumatic disorders, age 4 to 16 years, recruited within 1 month of starting a chronic systemic glucocorticoid regimen. Primary outcomes include suppression of bone turnover markers and safety assessments. Secondary outcomes include changes in bone density as measured by dual energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) densitometry at the radius and tibia.
The clinical efficacy of double filtration plasmapheresis(DFPP) in patients with antineutrophil cytoplasmic autoantibody associated glomerulonephritis(AAGN).
More than 100 hospital based outpatient wound centers in the USA and Puerto Rico agree to transmit structured data on all patients followed with chronic wounds and ulcers (e.g. diabetic foot ulcers, venous ulcers, pressure ulcers, arterial ulcers, surgical wounds, and traumatic wounds). Data are collected at point of care including adherence to wound care quality measures developed by the USWR as a Qualified Clinical Data Registry (QCDR).
This study will be conducted on 30 patients with mucocutaneous complaints and documented HCV infection. The study will be done at Tropical medicine department , Tanta university. It will be conducted between June2014 and November 2014. The aim of the study is to assess efficacy of Ribavirin in the management of mucocutaneous extrahepatic manifestations of HCV infection.
Background: - Vasculitis is a group of diseases that inflame and damage blood vessels and tissue. It can cause many medical problems. Few tests can diagnose the disease, and none can reliably predict a relapse. Researchers want to study people s genes and follow people over time to see how the disease affects them. Objective: - To learn the signs, symptoms, imaging tests, genetic markers, and blood tests that can help identify people with vasculitis and predict what will happen to them over time. Eligibility: - People age 3 and older who have or are thought to have vasculitis, or are related to someone with it. - Healthy volunteers. Design: - Participants will be evaluated by a doctor who has expertise caring for patients with vasculitis. - Participants will give a blood sample. Some will give a urine sample. - Some participants may have brushings or biopsies taken from the inside lining of the nose. - Images of participants blood vessels may be taken using scans. For some scans, participants will lie on a table that moves in and out of a cylinder that takes pictures. For some scans, a contrast agent may be injected into an arm vein. Other scans may use a radioactive form of sugar. Healthy minors will not have scans. - Some participants will answer questionnaires. - Some participants will have their tests done at NIH. Others will have their doctor take the blood, saliva, or cheek swab samples and send them to NIH. - Some participants will have one visit lasting 1-2 (but sometimes up to 4) days. Some participants may have follow-up visits every 3 - 6 months, indefinitely.
The overall objective of this project is to study the influence of modern anti-inflammatory treatments in established inflammatory rheumatic diseases (IRD) on immune response elicited by pneumococcal vaccination using 13-valent conjugate vaccine and influenza vaccination. In addition, the aim is to study the clinical aspects of vaccination regarding: tolerability in immunosuppressed patients with IRD, impact on existing rheumatic disease, possible association with onset of new autoimmune diseases, long-term immunity following pneumococcal vaccination, efficacy in preventing invasive pneumococcal diseases and influenza related serious infections. Results from this study are expected to bridge the existing knowledge gap and contribute to body of evidence needed for recommendations and implementation of vaccination program in IRD patients.
