Treatment of Ectopic Calcification in Fahr's Disease or Syndrome

Fahr DiseaseFahr Syndrome1 more

Fahr's disease or syndrome are neurodegenerative diseases in which patients present with bilateral vessel associated calcifications in the basal ganglia. The clinical penetration of Fahr's disease or syndrome is incomplete and heterogeneous comprising of neuropsychiatric signs, cognitive decline, movement disorders, and various other signs (migraine, speech disorders, pain, seizures). The symptoms start between 30 and 50 years and are (slowly) progressive. Symptomatic patients have an increased risk for dependence in activities of daily living and impaired quality of life. Currently, disease-modifying therapies are not available for patients with Fahr's disease or syndrome. However, in a small case series it was shown that alendronate was effective in the clinical treatment of several patients with Fahr's disease or syndrome. Now the time has come to investigate the effectiveness of treatment with bisphosphonates in patients with Fahr's disease or syndrome in a randomized controlled trial.

CAlcified Lesion Intervention Planning Steered by OCT.

Coronary Artery CalcificationAngioplasty

Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. The presence of calcifications increases the risk of adverse evolution after PCI , including stent restenosis, thrombosis and need for repeat revascularisation. Specific and appropriate tools can be used for calcified lesions management , including high pressure non compliant balloons, intravascular lithotripsy and rotablator. Intra vascular OCT has a high sensitivity and specificity for calcium detection among coronary artery lesions. Compared to IVUS, OCT allows a better quantification of calcium sheets (depth extension ) . Several intra coronary imaging based calcified lesions management algorithms have been proposed , but none have been validated in clinical practice.

Impact of Metformin on Peripheral Arterial Calcification in Type 1 Diabetes

Type 1 DiabetesPeripheral Arterial Calcification

Vascular calcification (VC) is a complication frequently observed in elderly, in chronic kidney disease (CKD) and in diabetes (particularly in type 1 diabetes). VC is a dynamic pathophysiological process that causes cardiovascular morbidity and is an independent risk factor of major amputation. In vitro and human observational studies have suggested a role of metformin in preventing VC. The investigators propose to test the effect of metformin treatment during two years on lower limb arterial calcification evaluated by CT-scan in patients with type 1 diabetes and without CKD. This research is a phase III double blind randomized controlled trial consisting of 2 years double-blind treatment phase (patients randomized to metformin or placebo) in type 1 diabetic patients. The participants and the investigators will be blinded to the study medications taken during the double-blind treatment period

Mammography and Breast Arterial Calcification: An Information-Sharing Trial

MammographyVascular Calcification

The purpose of this research study is to determine the potential benefits of adding information on patients' breast arterial calcification (BAC) results to the standard results letter women receive after mammography. In addition to looking for potential breast cancer, research shows that mammograms can also detect the presence of calcifications within the breast arteries. Those calcifications can be associated with coronary artery disease. Right now, women are not routinely told whether or not they have BAC; that is, it's not part of standard practice to communicate that information to patients. However, previous research has suggested that patients would like to be informed about their BAC status more often. In this study, the team has two goals. First, the team wants to measure the rates of BAC in a large, diverse group of 14,875 women. Because most of the past research on BAC has largely been focused on White mammography patients, the researchers feel it is important to see if the results are similar or different in a more racially and ethnically diverse sample. Second, the study team wants to understand the effects of giving women information on their BAC results as part of their standard post-mammography letter. Specifically, the study team wants to see how sharing that information might affect women's healthcare choices and lifestyle. The research will include 1,888 women in this second part of the study, which will be the first in the literature to explore women's reactions to BAC information. If research shows that women find the information useful, BAC information may be given to women regularly in the future.

Mitral Annular Calcification

The purpose of this study is to establish the safety and feasibility of the Edwards SAPIEN 3 valve in subjects with mitral annular calcification (MAC) associated with mitral stenosis (MS) and/or mitral regurgitation who are at high-risk for mitral valve surgery or deemed inoperable due to the extent of calcification.

This study is a prospective, single-arm, multi-center feasibility clinical study of the Tendyne Mitral Valve System for the treatment of eligible subjects with symptomatic, severe mitral regurgitation and severe mitral annular calcification (MAC). Subjects satisfying the study inclusion/exclusion criteria will undergo a procedure to implant the Tendyne mitral valve replacement device.

Sodium Thiosulfate for Treatment of Calcinosis Associated With Juvenile and Adult Dermatomyositis...

DermatomyositisIdiopathic Inflammatory Myopathies

Background: Dermatomyositis (DM) and juvenile dermatomyositis (JDM) cause inflammation in the muscles. People with DM and JDM can develop calcium deposits in places they should not, known as calcinosis. Calcinosis can be painful and cause disabilities and other problems. Researchers want to learn more about calcinosis to find treatments for it. Objective: To test if sodium thiosulfate (STS) can treat people with DM with calcinosis. Eligibility: People ages 7 and older who have moderate or severe calcinosis. They must have stable DM and calcium deposits in the torso or at least 2 limbs. Design: Participants will be screened with: Medical history Physical exam Muscle strength and function tests Blood and urine tests Participants will have several visits: 7-day pre-treatment visit about 10 weeks before starting STS Treatment visits over 10 weeks. They will get STS 3 times a week through IV infusion. They may be hospitalized the whole time. If they tolerate the drug, they may be discharged at certain times. During these times, they will return for the infusions. 3- to 5-day post-treatment visits 24 weeks and 62 weeks after starting STS. Visits may include repeats of screening tests and: Questionnaires Scans: They lie in a machine that takes pictures of the body. They may be injected with a radioactive agent. Durometry: A small instrument applies pressure on the skin or exposed calcinosis. Measurements of blood flow in the arms and fingernail blood vessels Photographs of the skin Kidney ultrasound Tests of kidney function Calcinosis aspiration: A needle placed into areas of calcinosis removes liquid.
