Active clinical trials for "Collagen Diseases"

The purpose of this research is to obtain ovarian tissue from female participants who will receive therapy which is expected to result in a loss or impairment of ovarian function and/or infertility and wish to preserve (freeze) ovarian tissue for the purpose of initiating a pregnancy in the future. Removal of the ovary for cryopreservation is an investigational procedure. 100% of the tissue will be used for the participant's future use. There have been 86 pregnancies as a result of frozen ovarian tissue that has been re-implanted back into the pelvis and hormonal function has been restored in individuals for up to 7 years. By doing this study, the investigators hope to learn of how to successfully freeze and thaw ovarian tissue in a manner that permits subsequent use by patients at some point in the future. Participation may also advance our knowledge of how to successfully mature follicles and oocytes (eggs) that are contained in these tissues which may help others in the future.

The trial is a prospective, observational study aiming to identify risk factors for serious COVID-19 infection by evaluating clinical measures and biomarkers of inflammation in patients with inflammatory rheumatic disease hospitalized with COVID-19 compared with control groups.

A retrospective monocentric study with large active files of patients monitored for rheumatoid arthritis, spondyloarthritis and systemic lupus erythematosus with as main endpoint the morbimortality of Covid-19 in these patients (number of patients hospitalized in conventional units and/or in intensive care and/or deceased). The results will be compared with those of the general population based on the epidemiological data of Covid-19.

This study will collect white blood cells or plasma (the liquid part of the blood), or both, from healthy volunteers and from patients with rheumatic or kidney disorders for research purposes. Rheumatic disorders involve abnormalities of the immune system, the body s defense against disease. The immune system consists of white blood cells such as lymphocytes and monocytes, which produce substances such as antibodies and cytokines. White cells and plasma will be collected through a procedure called apheresis (described below). Healthy volunteers and patients with confirmed or suspected rheumatic or kidney disease who are 18 years of age or older may be eligible for this study. Patients must be participating in a current protocol of the National Institute of Arthritis and Musculoskeletal and Skin Diseases or the National Institute of Digestive, Diabetes and Kidney Diseases. All candidates will be screened with a history, physical examination, and blood tests for hepatitis B and C and HIV infection. Women of childbearing age will be tested for pregnancy. Routine blood tests will be done in all volunteers, and in patients where needed. Pregnant women and people who test positive for hepatitis or HIV may not participate. Participants will undergo apheresis to collect lymphocytes, monocytes, or plasma from the blood. For this procedure, a needle is placed in a vein in the arm. Blood flows from the vein through a tube (catheter) into a machine that spins the blood, separating it into its components. The required cells or plasma are extracted, and the rest of the blood, including the red cells and platelets, is returned to the body through the same needle or through a second needle placed in the other arm. Cells collected from volunteers will be used in studies comparing the number and function of similar cells from patients with rheumatic diseases, focusing on the differences in number and function of the cells in health and disease. Components collected from patients will be used only for studies described in the protocol in which they are currently enrolled. ...

Randomized controlled trial including 100 subjects with rheumatic diseases and biological treatment with a 28 point-Disease Activity Score(DAS28)3.2 or less. The subjects will be randomized to either nurse-led clinic or rheumatologist-led clinic. The hypothesis is that there will be no difference in DAS28 between the two groups after 1 year follow-up.

A qualitative study assessing the impact of early narrative medicine practice on Medical Honors Program (MHP) students' attitudes regarding patient-centered interactions, through interviewing patients with chronic or life-limiting illnesses to obtain their illness stories. MHP students will develop a patient narrative for the patients interviewed. These narratives will be edited by the patient, and, with the permission of the patients, may be published as a collection of stories.

This is a prospective multicenter study of the LPS-Flex Porous Femoral Components when used in primary total knee arthroplasty. The purpose of the study is to obtain short-, mid-, and long-term clinical outcomes and implant survivorship data for the NexGen LPS-Flex Porous Femoral components.

The aim of this study is 1) To describe the level and determinants of methotrexate adherence in patients with chronic inflammatory rheumatism (rheumatoid arthritis, spondyloarthritis and psoriatic arthritis) in the department of rheumatology in the Nîmes University Hospital

Observational registry to assess the longer-term risk of serious infections and malignancies reported with TNFα-blocker therapy, as well as the longer-term risk of cardiovascular and thromboembolic events in adult Rheumatoid Arthritis (RA) patients treated with Cimzia® as compared to non-biologic DMARD-treated controls.

Osteoporotic vertebral fracture (VF) and osteonecrosis of the femoral head (OFH) are major concerns in patients with systemic rheumatic diseases treated with high-dose glucocorticoids (GCs). The investigators examined and compared the incidence and risk factors of VF with those of OFH in patients who had recently received high-dose GC therapy to clarify the relationship between these two complications.
