Active clinical trials for "Sclerosis"

Today, the study of gut microbiota has taken a prominent place in several fields of medical research. Numerous experimental data in humans and animals suggest that an imbalance in the composition of the microbiota could contribute to the pathophysiology of systemic autoimmune diseases such as Systemic Sclerosis (SCS). A future exploration of the microbiota, a source of diagnostic and/or prognostic biomarkers, may be very useful for tomorrow's medicine by proposing therapeutic interventions based on the correction of possible imbalances in the intestinal flora. Studies of the human gut microbiota in patients with ScS are limited to low-impact investigations, due to the lack of data on the clinical and biological characterization of the patients studied, and to the absence of longitudinal studies in the same patient. For this reason, we are interested in exploring the intestinal microbiota of ScS patients in a comprehensive and longitudinal way.

New research in animal models of MS suggests that greater training intensity is required to restore lost functions. We have developed and tested vigorous intensity cool room treadmill training that people with MS who have fatigue and heat-sensitivity can tolerate. This study will focus on the appropriate dosage of training.

Systemic sclerosis (SSc) is a rare form of connective tissue disease characterized by vascular involvement and the intensity of fibrosis. The lack of available treatment is largely due to the very fragmented understanding of the pathophysiology of SSc. However, one of the keys to conducting quality research on this disease remains the development of well-documented patient cohorts with reliable biological samples. The main objective of this cohort is to study the natural progression of SSc in a cohort of patients followed over 5 years.

Background: Amyotrophic lateral sclerosis type 4 (ALS4) is an inherited motor neuron disease. People with ALS4 have a change in the amount of RNA and DNA that bind together. This binding of RNA with DNA forms units called R-loops. Researchers want to learn how R-loops are related to ALS4. To do this, they will study people with inherited neurological conditions that may affect R-loop levels. These include ALS4, progressive external opthalmoplegia with mitochondrial deletions (PEOB2), Aicardi-Goutieres syndrome (AGS), and ataxia and oculomotor apraxia type 2 (AOA2). Objective: To learn how the binding of RNA with DNA (R-loops) is related to neurological disease. Eligibility: People age 5 and older with ALS4, PEOB2, AGS, and AOA2. Healthy relatives and nonrelatives are also needed. Design: Participants may be screened with a review of x-rays and other medical records. Healthy relative and nonrelative participants will have 1 visit. All other participants will have 4 visits over 3 years. At visits, participants will undergo some or all of the following: Medical history Physical exam Tests of muscle strength and volume and physical function Blood tests Pregnancy test (for some females) Skin biopsy of forearm Magnetic resonance imaging (MRI) Dual x-ray absorptiometry (DEXA). Some tests are optional. The MRI uses a magnetic field and radio waves to take pictures. Participants will lie on a table that slides in and out of the scanner. The scanner makes noise. They will get earplugs. The DEXA scan uses x-rays to take pictures. MRI and DEXA will be used to measure muscle, fat, and lean body mass. ...

Early diagnosis is a key factor for effective treatment of multiple sclerosis. Accelerometer and gyroscope measurement of tremor could screen potential motor control dysfunction and predict a risk for development of multiple sclerosis.

The influence of pregnancy on the course of multiple sclerosis (MS) has long been a controversial topic. After the publication of the first large prospective study of pregnancy and MS in 1998, counselling of women with MS has radically changed and many patients have been able to fulfill their desire of motherhood. However, there are still some challenges for the neurologist, who has to face old unanswered questions or new issues, regarding the use of disease modifying drugs (DMDs) in this period of life, effects on the short and long term outcome of the mother (in terms of relapses and disability) and the child, role of breast-feeding and locoregional analgesia. To set up a national prospective pregnancy registry for patients with MS, nested within the Observatoire Français de la Sclérose en Plaque (OFSEP) cohort, owing to a better knowledge of interactions between MS and pregnancy-related issues (pregnancy itself, locoregional analgesia, breastfeeding, impact of using or stopping DMDs on women/children…)

This study highlights the global management of the various components of outpatient pain by hypnoanalgesia (pain management by hypnosis) in radiopediatrics. Indeed, pain is induced by sclerosis of cutaneous angiomas in interventional radiology. It is managed by MEOPA (an equimolar mixture of oxygen nitrous oxide) or by general anesthesia. For four years, the medical electroradiology technologist of the Mother and Child Hospital (HFME) of the Hospices Civils de Lyon offer patients in addition a pain management by hypnoanalgesia. The investigator propose a multicenter open randomized study comparing two pain management strategies, in children aged 7 to 18 years treated for cutaneous angioma by sclerosis in interventional radiology at the HFME. The two strategies studied are: Hypnoanalgesia and MEOPA (the reference strategy). The main objective is to evaluate the efficacy of hypnoanalgesia compared to the standard of care of pain, which is the use of MEOPA, in the treatment of sclerosis of cutaneous angioma in pediatric interventional radiology.

This study aims to measure the quality of life of ALS patients by the SRI questionnaire, in two distinct patient groups : Patient requiring initiation of NIV, and patients 24 hours dependent on NIV This study also seeks to assess the quality of life of the caregivers with the Zarit Burden interview in those two populations

Systemic sclerosis is an autoimmune and inflammatory disease characterized primarily by fibrosis and vascular involvement. We know that the immune system is disrupted in systemic sclerosis, but there are probably other mechanisms to explain the disease, including deregulation of certain proteins such as prolactin

The investigators hypothesize that hypogammaglobulinemia (defined as IgG serum concentration <7.0g/L) is a treatable cause of fatigue in people with MS: The primary objective is to prove the link between hypogammaglobulinemia and fatigue in patients with multiple sclerosis. The secondary objective is to show that fatigue is mediated via frequent infections in people with MS and hypogammaglobulinemia.
