Background: - Chronic leg ulcers are a complication of many blood disorders such as sickle cell disease, thalassemia, and other red blood cell disorders. In these disorders, red blood cells break down earlier than normal, which researchers suspect may cause or contribute to the development of leg ulcers; however, the exact cause is unknown, and current therapies are not very effective. Researchers are interested in determining if a research cream made with sodium nitrite, a substance that is known to increase blood flow by dilating blood vessels, may speed up the healing of skin ulcers. Objectives: - To evaluate the safety and effectiveness of topical sodium nitrite cream as a treatment for chronic leg ulcers in individuals with sickle cell disease or other red blood cell disorders. Eligibility: - Individuals at least 18 years of age who have sickle cell disease or another red cell disorder and have had a leg ulcer for more than 4 weeks. Design: * Participants will be screened with a physical examination, medical history, blood tests, and an examination of the ulcer, including x-ray of the leg(s) with the ulcer and swabs from the wound. * Participants will be scheduled for a 5-day inpatient stay at the Clinical Center, with the following procedures: * Days 1 and 2: Participants will have blood draws, a wound assessment, ultrasound of the affected leg, imaging studies (magnetic resonance imaging and infrared photography), thermo-patch application to monitor temperature changes, measurements of blood flow in the skin, and questionnaires about pain and quality of life. An optional skin biopsy may also be conducted with samples taken near the skin ulcer * Day 3: Participants will have one ulcer treated with the topical cream. Frequent blood draws will be conducted before application and then regularly for up to 6 hours after application of the cream. Thirty minutes after the research cream is applied, participants will have imaging studies of the treated leg and measurements of pain levels and blood flow. * Day 4: Participants will have a blood draw and temperature recordings taken. * Day 5: Participants will have the research cream applied and the same imaging studies as before, and will be discharged for care at home. * For the following 3 weeks, participants will come to the clinical center twice a week to have the research cream applied to the leg ulcer and tests performed by the study researchers. * For the fourth and final week, participants will return for additional cream treatment sessions, imaging studies, blood draws, and other tests as directed by the study researchers. * Study participation will end in the following week (week 5). Subjects will come for a final visit one month after the end of the study.
The purpose of this clinical investigation is to evaluate the safety and efficacy of Amnion/Chorion/Amnion allograft , Amnion/Chorion allograft, and/or Amnion/Amnion allograft, plus Standard of Care (SOC) each versus SOC alone in the treatment of chronic non-healing diabetic foot ulcers (DFU) after 12 weeks of treatment.
Approximately 60 subjects will be enrolled into this double-blind, placebo-controlled study for the Deferoxamine Intradermal Delivery Patch (DIDP). Those subjects who pass Screening will enter into the 2-week Standard of Care (SOC) Run-In period. During this time, ulcers will be assessed to check healing based on digital planimetry, and qualitative features of the ulcer. Subjects who meet eligibility criteria at the end of the 2-week Run-in Period will be randomized into active and control groups (2 active to 1 placebo) and enter the 12-week Treatment Period. At each visit during the Treatment Period, the target ulcer will be measured by digital photographic planimetry, the Principal Investigator will assess the wound qualitative attributes, and the DIDP (or placebo patch) will be placed as the primary wound dressing. At each visit the subject will also receive/review a daily diary to document pain , study drug compliance, and analgesic use.

Background: Chronic granulomatous disease (CGD) is a disease of the immune system, which is how the body fights germs. People with CGD get infections easily and have other health problems. Some medicines to treat CGD have a lot of side effects and do not always work. Researchers want to see if a new drug can help. Objective: To see if tofacitinib is safe to use for treating chronic CGD. Eligibility: Adults aged 18 and older with CGD who have not had success with other treatments and who are enrolled on NIH study # 93-I-0119. Design: Participants will be screened with the following: Physical exam Medical history Blood, urine, and stool tests Pregnancy test, if needed An upper gastrointestinal endoscopy and/or colonoscopy, if needed for their symptoms. Tissue samples will be collected. Skin assessment, if needed Participants will repeat some screening tests at visits. Participants will complete questionnaires about their general health and how CGD affects their daily life. Photographs will be taken of their skin, if needed. They will have lung function tests, if needed. They will have a computed tomography (CT) scan of the chest, abdomen, and pelvis, if needed. A CT scan uses X-rays to create pictures of the inside of the body. Participants will gradually reduce the amount of some CGD medicines they take. Then they will take tofacitinib as a pill twice a day or once a day for 3 months. They will keep a drug diary. They will have monthly study visits. They will have a follow-up visit about 1 month after their last study drug visit. Participation will last for about 6 months.
Background: Bacteria that live inside the stomach and intestines are important for health. Chronic granulomatous disease (CGD) and inflammatory bowel disease (IBD) can make people have unhealthy bacteria. This can lead to gastrointestinal (GI) problems. Researchers want to see if people with CGD and IBD feel better when they change the bacteria in the stomach by following a special liquid diet. Objective: To see if an elemental diet can change the bacteria in the stomach and intestines of people with CGD and IBD. Also, to see if this helps GI symptoms. Eligibility: People ages 8-65 years with CGD, CGD-associated colitis, and IBD. Design: Participants will first be screened with: Upper GI endoscopy and/or colonoscopy. A long, thin tube with a tiny camera at the end will be passed into the participant s body through the mouth or anus. Tissue will be collected. Participants will be sedated for the procedure. They will be sedated using a special mask or small plastic tube placed in an arm vein using a needle. Participants will be put on the special diet for up to 4 weeks. They will stay in the hospital for up to 2 weeks. They will have check-ups. They will have blood, urine, and stool samples collected. They will keep a symptom diary to record how they feel and any GI symptoms. Participants will have 2 follow-up visits. The first will be right after they finish the diet. The second will be 4 weeks later. They will have blood, urine, and stool samples collected. They will learn about re-introducing other foods into their diet.
Background: This study follows people who have had, or will soon have, a transplant using stem cells from another person. This is known as an allogeneic hematopoietic stem cell transplant (HSCT). Graft-versus-host disease (cGVHD) can happen after HSCT. cGVHD can cause mouth problems and more serious issues. Researchers want to study changes in the mouth that might indicate cGVHD. Objective: To identify cGVHD in the mouth and better understand the development, treatment, and progress of post-transplant changes in the mouth. Eligibility: Adults at least 18 years old who will soon undergo HSCT or have had one in the past 3 years Healthy adults at least 18 years old Design: All participants will have a screening visit and baseline visit. They will last 60-90 minutes. Over these two visits, participants will have: Medical and dental history Dental exam. Questions about their eating habits and general health Blood drawn through a needle in the arm Vital signs taken Pictures of their mouth and lips taken Questions about their oral health, including about pain, sensitivity, or dryness Saliva samples taken. Participants will spit into a sterile plastic tube. Swabs taken of the mouth and some of the saliva, plaque, and fluid from the spaces between teeth and gums. Participants may also have: A piece of skin taken (biopsy) from the inner lining of the cheeks A piece of skin taken (biopsy) from the lower lip Dental X-rays Urine pregnancy test Most participants will have at least 7 study visits over 3 years. They will meet with a dentist and repeat baseline tests.
