4 Clinical Trials for Various Conditions
This study plans to learn more about Down syndrome. The investigators think there is a different level of the AIRE gene in individuals with Down syndrome. The investigators think that the AIRE gene level can provide more insight about depressed immune cell function in individuals with Down syndrome. Patients are being asked to be in this research study because the investigators want to see if their blood contains more of less of the AIRE gene.
Background: Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a problem of the immune system. In people with APECED, the immune system makes a mistake and attacks the body. Some people with APECED have a type of hair loss called alopecia areata (AA). No drugs are approved to treat AA. Objective: To see if a study drug (ruxolitinib) can help hair regrowth in people with APECED-associated AA and if it can improve other symptoms caused by the immune system s attack to the body. Eligibility: People aged 12 to 65 years with APECED and severe AA. Design: Participants will be in this study for up to 10 months. They will have 5 in-person visits and 6 televisits, each about 4 weeks apart. One in-person visit may be up to a 10-day stay in the hospital. The first in-person visit will include screening. Participants will have a physical exam. They will have blood tests. Photographs may be taken of their skin. They will answer questions about their quality of life. Participants will begin taking the study drug during their hospital stay. They will take the pills by mouth twice a day for 8 months. Researchers may take tissue samples from participants scalp, gums, and lower lip. Participants may provide samples of urine, stool, nail clippings, and saliva. They may have an eye exam and an ultrasound exam of their abdomen. Some tests may be repeated in subsequent in-person visits. In telehealth visits, participants will answer questions about how they are feeling. They will describe and send photos of hair regrowth. They will be asked to have blood drawn and the results sent to the researchers.
This is an open-label, dose-titration trial to study the efficacy, safety, and pharmacokinetics of oral cochleate amphotericin B (CAMB) in the treatment of mucocutaneous candidiasis infections in patients who are refractory or intolerant to standard non intravenous therapies.
Background: - The immune system is made up of special cells, tissues, and organs that fight infections. Problems with this system may lead to frequent, severe, or unusual fungal infections. These infections are often difficult to treat. Researchers want to collect blood and tissue samples from people who have unusual, persistent or severe fungal infections or immune problems that increase the risk of these infections. Objectives: - To collect medical information and samples for a long-term study of people with immune system problems that lead to fungal infections. Eligibility: * People with a history of fungal infections caused by immune system problems. * Parents, children, and siblings of this group. * Healthy volunteers not related to the first two groups. Design: * This long-term study may last for up to 10 years. Those in the study may need to provide new information about every 6 months. The procedures for each person may vary with the particular diagnosis and the extent of fungal infection. Healthy volunteers may have only one or two visits. * At the first visit, those in the study will have a full medical history and physical exam. They will also provide blood. * Research procedures may include the following: * Saliva, urine or stool testing * Mouthwash collection for DNA testing * Collection of cheek cells, nail clippings, or vaginal fluid * Tests of leftover tissue or body fluid from previous medical procedures * Skin or oral mucous membrane biopsy * Collection of white blood cells * Followup visits will involve a physical exam and updated medical history. Blood, saliva, urine, or nail clipping samples may be taken for ongoing studies. Any additional tests or exams required by the study doctors may also be done. * Participants may withdraw from the study pool at any time.
