Active clinical trials for "Syndrome"

This research is being performed to try to understand if the use of deep brain stimulation or DBS can treat the symptoms of Tourette syndrome that do not respond well to current medications. In order to do this the investigators will place small stimulation leads on both sides of the brain in a region (a portion of the thalamus) that may alter the abnormal activity in the brain contributing to the symptoms of Tourette syndrome. This requires two surgical procedures, and several preoperative and postoperative visits for tuning the stimulation parameters and recording stimulation effects. The FDA has not approved DBS for use in people with Tourette syndrome, and Medtronic (the manufacturer of the device) has not conducted testing for the system in Tourette syndrome. Therefore its use in this study is experimental.

The purpose of this study is to evaluate the safety and efficacy of custom made devices, Zenith t-Branch devices and physician modification of FDA approved off-the-shelf endovascular grafts in the treatment of patients with complex abdominal aneurysms, aortoiliac aneurysms, thoracoabdominal aneurysms and aortic arch aneurysms who (1) have anatomy not suitable for endovascular repair using grafts currently marketed in the United States,(2) are deemed unsafe to wait the required time necessary for commercial endograft manufacturing, and (3) are at high risk for open surgical repair. Amendment to the study has created a cohort open to people with connective tissue diseases such as Marfan, Ehlers-Danlos or Loey-Dietz syndromes to enroll in the trial. An additional amendment to the study allows the use of a custom made device to treat an aneurysm in the aortic arch.

Objective: To determine the metabolic effects of the adrenalectomy in subclinical Cushing's syndrome of adrenal incidentaloma. Methods: 234 subclinical cushing syndrome and adrenal incidentaloma will be randomly assigned into two groups(e.g adrenalectomy group and conservative treatment group).

This is a standard of care treatment guideline for allogeneic hematopoetic stem cell transplant (HSCT) in patients with primary immune deficiencies.

Background: Stem cell transplants from related donors (allogenic stem cell transplants) can be used to treat individuals with certain kinds of severe blood diseases or cancers, such as severe anemia. Allogenic stem cell transplants encourage the growth of new bone marrow to replace that of the recipient. Because stem cell transplants can have serious complications, researchers are interested in developing new approaches to stem cell transplants that will reduce the likelihood of these complications. By reducing the number of white blood cells included in the blood taken during the stem cell collection process, and replacing them with a smaller amount of white blood cells collected prior to stem cell donation, the stem cell transplant may be less likely to cause severe complications for the recipient. Researchers are investigating whether altering the stem cell transplant donation procedure in this manner will improve the likelihood of a successful stem cell transplant with fewer complications. Objectives: - To evaluate a new method of stem cell transplantation that may reduce the possibly of severe side effects or transplant rejection in the recipient. Eligibility: Recipient: Individuals between 4 and 80 years of age who have been diagnosed with a blood disease that can be treated with allogenic stem cell transplants. Donor: Individuals between 4 and 80 years of age who are related to the recipient and are eligible to donate blood. OR unrelated donors found through the National Marrow Donor Program. Design: All participants will be screened with a physical examination and medical history. DONORS: Donors will undergo an initial apheresis procedure to donate white blood cells. After the initial donation, donors will receive injections of filgrastim to release bone marrow cells into the blood. After 5 days of filgrastim injections, donors will have apheresis again to donate stem cells that are present in the blood. RECIPIENTS: Recipients will provide an initial donation of white blood cells to be used for research purposes only. From 7 days before the stem cell transplant, participants will be admitted to the inpatient unit of the National Institutes of Health Clinical Center and will receive regular doses of cyclophosphamide, fludarabine, and anti-thymocyte globulin to suppress their immune system and prepare for the transplant. After the initial chemotherapy, participants will receive the donated white blood cells and stem cells as a single infusion. After the stem cell and white blood cell transplant, participants will have regular doses of cyclosporine and methotrexate to prevent rejection of the donor cells. Participants will have three doses of methotrexate within the week after the transplant, but will continue to take cyclosporine for up to 4 months after the transplant. Participants will remain in inpatient care for up to 1 month after the transplant, and will be followed with regular visits for up to 3 years with periodic visits thereafter to evaluate the success of the transplant and any side effects.

Background: - Researchers want to develop better ways to treat cancer. In this study, they will give people with cancer two drugs. These drugs have been used on their own to treat some blood cell cancers. Objectives: - To test the safety and efficacy of the drug combination of bortezomib and clofarabine. Eligibility: - Adults age 18 and over with advanced cancer that has progressed after receiving standard treatment or that has no effective therapy. Design: Participants will be screened with medical history, physical exam, and scans to measure their tumors. They will also have heart, blood, and urine tests. All of these may be done by their regular doctors. Participants will get the study drugs in 21-day cyles. They will stay at the clinic for week 1 of every cycle, then have 2 weeks off. <TAB>- Bortezomib will be injected under the skin on days 1 and 4. <TAB>- Clofarabine will be injected in a vein for days 1-5. During cycle 1 only, participants will go to the clinic or their doctor to have a physical exam and blood tests at the start of the second and third week. Participants will have clinical evaluations throughout the study, including before receiving treatment and then before the start of each cycle. Participants may stay in the study as long as they are tolerating the drugs and their tumor is not getting worse. Participants will have follow-up for 30 days after the last dose of study drugs. The first part of this study tests the safety of different doses of clofarabine and bortezomib. The second part of this study involves a separate group of participants who will undergo mandatory research biopsies to learn more about the effects of clofarabine and bortezomib on cancer cells.

RATIONALE: Giving chemotherapy, such as busulfan, fludarabine, and melphalan, before a donor umbilical cord blood stem cell transplant helps stop the growth of abnormal or cancer cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well combination chemotherapy followed by a donor umbilical cord blood transplant works in treating infants with high-risk acute leukemia or myelodysplastic syndromes.

The goal of this phase 1/2 multicenter, open-label, singe arm dose escalation and expansion study is to assess the safety, tolerability, pharmacokinetic and pharmacodynamic profile of CTX-712 in patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) and higher risk myelodysplastic syndromes (HR-MDS). The phase 1 part of the study consists of sequential standard 3 + 3 dose escalation, where patients will receive ascending doses of CTX-712 to determine the recommended phase 2 dose (RP2D) for further clinical development. This is followed by a confirmatory phase 1 expansion cohort where an additional approximately 10 patients will be treated with CTX-712 at the RP2D to gain further confidence in the selected dose level. After RP2D is determined, Drug-Drug-Interaction cohorts will be started. The phase 2 part of the study will commence after the RP2D has been identified and confirmed and will evaluate therapeutic activity in R/R AML or R/R HR-MDS, in addition to confirmation of the safety profile.

The Eisenmenger syndrome corresponds to the most advanced form of pulmonary arterial hypertension associated with congenital heart disease. The syndrome causes chronic hypoxemia, with an increase in erythrocyte mass, which predisposes to thrombotic complications. Pentoxifylline is a xanthine derivative and it is considered as a hemorrheological agent with described effects of reduction in erythrocyte and platelet aggregation, adhesion and activation of leukocytes, and endothelial damage. The main objective of this study is to verify if the chronic oral administration of pentoxifylline to Eisenmenger patients induces an increase in the circulating levels of thrombomodulin, a naturally occurring proteoglycan with anticoagulant, anti thrombotic and anti-inflammatory properties.

This randomized controlled pilot study will be evaluating an app, MORT-PFPS app (ETH-01K), owned by EverEx, Inc., to examine safety and effectiveness in individuals with patellofemoral pain syndrome.
