Active clinical trials for "Syndrome"

Irritable Bowel syndrome - constipation predominant (IBS-C) is a chronic and disabling,disorder of the gut that is characterized by abdominal pain or discomfort. Approximately 50% of patients with IBS-C will also meet criteria for anxiety or depression. Anti depressant medication is widely used in the treatment of IBS. Linaclotide is a novel medication for IBS that is also effective at relieving pain associated with IBS, which may be in part to signalling between the gut and the brain. However, the impact of Linaclotide on the psychiatric symptoms of anxiety and depression on IBS has not been investigated.

The purpose of this study is to determine whether therapy that has been shown to be beneficial for mitochondrial diseases is also beneficial for Chronic Fatigue Syndrome (CFS) patients. This study is a chart review of previous CFS patients who received daily conditioning exercise, a high protein diet and nutraceutical therapy (ENT). Prescribed nutraceutical supplements included alpha-lipoic acid, acetyl-L-carnitine, omega-3fatty acids (maxDHA), coenzyme Q10 (CoQ10), plus a multivitamin. Twelve CFS male and female patients between the ages of 20-70 years will be recruited to participate in this pilot study. Subjects will be eligible to participate if they meet the criteria for CFS of the Centers for Disease Control and Prevention (CDC). These include persistent, unexplained fatigue for at least 6 months, concurrent with four of the following: impaired memory/concentration, sore throat, new headaches, unrefreshing sleep, muscle pain, multi-joint pain, tender lymph nodes, and post-exertional malaise.

Subjects presenting with probable acute coronary syndromes scheduled for cardiac catheterization will be enrolled in this study. Consented subjects will be randomized to receive ticagrelor started with a loading dose immediately after enrollment versus receiving a loading dose of ticagrelor during cardiac catheterization after diagnostic angiography but prior to stenting. Optical coherence tomography (OCT) will be performed after stenting and the volume of thrombus within the new stent will be measured and compared between the groups.

This study will evaluate and treat people with SARS, a new type of pneumonia (lung infection) originating in China. SARS is caused by a new virus that is easily transmitted from person to person. This study will look at the course of the disease; determine how the virus affects the body and how the body fights the infection; and evaluate diagnostic tests to quickly identify the disease. People 18 years of age and older with probable or suspected SARS may be eligible for this study. Close contacts of patients with SARS, patients who recovered from SARS, and NIH health care workers involved in the care of patients will also be enrolled. Patients with SARS who require hospitalization will be admitted to the NIH Clinical Center. Because SARS spreads easily, hospitalized patients will be in a room by themselves and will not be allowed any visitors. They will not leave their room except for tests, such as x-rays. All participants will have a full medical examination, including a medical history, physical examination, and blood tests. In addition, the participants undergo various tests and procedures as follows: Probable and suspected SARS patients may be hospitalized or may be seen as outpatients. They are provided the treatment judged best for their disease, usually according to expressed or published recommendations. The best treatment for SARS is not yet known, and there have been no studies evaluating therapies. Outpatients are seen three times a week for 2 weeks, once a week for 4 more weeks, and then at 6 months. Patients have mouth and throat swabs taken three times a week for the first 2 weeks, then once a week for 4 more weeks. Blood is drawn three times a week for the first 2 weeks, then once at weeks 3, 4, and 6. If virus is still detectable after 6 weeks, nose washings and throat swabs are repeated until no virus is detected for 3 weeks in a row. In addition, patients provide urine and stool samples, have a chest x-ray and electrocardiogram, and undergo bronchoscopy and bronchial lavage. For the bronchoscopy, a bronchoscope (pencil-thin flexible tube) is passed into the large airways of the lung, allowing the physician to examine the airways. Cells and secretions from the airways are rinsed from the lung with salt water. A brush the size of a pencil tip is passed through the bronchoscope to scrape cells lining the airways and pieces of tissue are collected for analysis. Close contacts of patients are evaluated twice a week for 2 weeks, then once a week for 2 more weeks. Blood is drawn at the first visit and then at 1, 2, and 4 weeks. Mouth and throat swabs, nose washings, and sputum collections are done twice a week for 2 weeks, then once a week for 2 more weeks. Urine and stool samples are collected once a week for 4 weeks. If virus from the nose or throat is still detectable after 4 weeks, weekly nose washings and throat swabs continue until no virus is detected for 3 weeks in a row. Blood may also be drawn during the weekly visits. Recovered SARS patients provide blood, urine, and stool samples and have a mouth and throat swab and nose aspiration to see if the SARS virus is present. For the nasal aspiration, salt water is put in the nose and then suctioned out. Usually, these tests are done only once. If virus is detected, however, the nose washing, throat swabs and blood tests are repeated once a week until no virus is detected for 3 weeks in a row. Health care workers document their contact with patients, use of isolation procedures and equipment, and any unexpected events that occur during contact. They are evaluated for symptoms of infection and provide a blood sample once a month

Normal bone marrow function depends on the coexistence of normal hematopoietic stem cells and a microenvironment mostly located in the medullary part of the bones. Stem cells cannot function properly in the absence of an adequate microenvironment. Whereas in malignant and non-malignant hematologic diseases caused by a deficiency or abnormal stem cells, stem cell transplantation is the treatment of choice that results in a cure, in diseases such as MDS, myelofibrosis, and other conditions associated with an abnormal microenvironment, pancytopenia may occur despite the presence of apparently normal hematopoietic cells with no recognizable cytogenetic abnormality. We, the investigators at Hadassah Medical Organization, proved in experimental studies that the entire osteohematopoietic complex consisting of trabecular bone, hematopoietic microenvironment (of stromal origin) and hematopoietic tissue has been successfully transferred directly into ablated bone marrow cavity in a one-step transplantation procedure. The goal of this study is to enhance hematopoiesis in patients with myelofibrosis syndrome by intraosseous inoculation of demineralized bone matrix (DBM) together with allogeneic bone marrow cells (BMC).

This natural history study is a prospective and retrospective, observational study of WHIM patients. WHIM syndrome is a rare, genetic, primary immunodeficiency disorder (a disorder in which the body's immune system does not function properly). WHIM is an acronym for some of the symptoms of the disorder - Warts, Hypogammaglobulinemia (low levels of certain antibodies), Infections and Myelokathexis (too many white blood cells in the bone marrow).This study includes 10-year retrospective (Retrospective Phase) and up to 5-year prospective (Prospective Phase) components.

The purpose of this study is to determine if treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure in women with both OSA and polycystic ovarian syndrome will improve the regularity of the women's menstrual cycles.

Fragile X syndrome (FXS) is the most common genetic cause of autism spectrum disorder (ASD). The investigators wish to examine brain distribution of sigma-1 receptors in young adult males with FXS using 18F-FTC-146 PET. This project will study the distribution of sigma-1 receptors in 15 young (18-30 years) male adults with FXS compared to 5 healthy adult volunteers.

The NET-PACS trial is a Prospective Assessment of patients with neuroendocrine tumors and current or prior history of Carcinoid Syndrome or diarrhea undergoing peptide receptor radionuclide therapy with or without telotristat ethyl. The main goal of the study is to demonstrate the feasibility of serial in-depth assessment of patients with neuroendocrine tumors and current or prior history of carcinoid syndrome or diarrhea undergoing treatment with PRRT using telotristat ethyl compared to placebo. We aim to report and describe from a patient's perspective the multi-faceted impact of carcinoid syndrome in patients with NETs and the changes on treatment while getting PRRT using telotristat ethyl compared to placebo.
