The goal of this study is to assess whether canagliflozin has a renal and vascular protective effect in reducing the progression of renal impairment relative to placebo in participants with type 2 diabetes mellitus (T2DM), Stage 2 or 3 chronic kidney disease (CKD) and macroalbuminuria, who are receiving standard of care including a maximum tolerated labeled daily dose of an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB).
NCT00006301
This study will identify and characterize immune factors involved in hepatitis C infection and elimination of the virus. Individual responses to hepatitis C infection vary; some people are able to eliminate the virus, whereas others remain chronically infected. This study may identify factors important in preventing infection that may be of help in developing a vaccine or more effective treatments. People over 18 years old who have been exposed to hepatitis C virus may participate in this study. Subjects will be recruited from the National Institutes of Health, Inova Fairfax Hospital, Occupational Medical Services-IDP P.C., Washington Hospital Center and Holy Cross Hospital, all in the Washington, D.C. metropolitan area. Individual patients from other centers will also be recruited on a case by case basis. Participants will have 40 to 60 cc (1 to 2 ounces) of blood drawn at seven intervals. The first collection will be as soon as possible after exposure to hepatitis C virus and then again at 2, 4, 6, 12, 24, and 48 weeks after exposure. The white blood cells will be studied for their response to the virus, and markers for infection will be followed. If infection develops, additional samples of blood may be requested, and patients will be offered evaluation for treatment. Test results will be kept confidential and will not be entered into any medical records.
NCT00031304
Healthy volunteers will be screened under this protocol for possible participation in a study testing a vaccine against HIV, the virus that causes AIDS. Healthy adults 18 to 60 years of age may be eligible for this study. Participants must be in good general health with no history of significant medical problems or abnormal laboratory test results. Pregnant or breast-feeding women and people infected with HIV will not be enrolled. Participants enrolled in this protocol will undergo the following tests and procedures within 8 weeks before the start of the experimental vaccine study: * Medical history, including history of sexual activity and drug use * Physical examination * Pregnancy test for women of childbearing age * Blood and urine tests to evaluate possible medical problems such as liver and kidney function; to evaluate immune function; and to test for HIV, hepatitis and syphilis Individuals who are identified through this screening protocol as possible candidates for an HIV vaccine trial will be provided additional information about study options.
NCT00195637
This study will evaluate patients with Hereditary Inclusion Body Myopathy (HIBM) and examine the effects of immune globulin (IG) treatment on muscle and muscle function. HIBM is a progressive neuromuscular disease that begins in early adulthood, primarily affecting limb muscles. It results from mutations of the gene that is responsible for producing sialic acid, a sugar normally found on the surface of certain proteins, including alpha-dystroglycan, which is involved in muscle function. Some patients with HIBM have decreased sialic acid on the alpha-dystroglycan protein, which may be the cause of their muscle weakness. IG is a protein in the blood that carries a large amount of sialic acid. This study will administer IG to patients with HIBM and determine if the sialic acid in IG is taken up by muscle cells in these patients and if it can restore some of their muscle function. Four patients with HIBM will be admitted to this study at the NIH Clinical Center for evaluation and IG treatment. The evaluation lasts about 1 month. After completing baseline studies (see below), patients receive two intravenous doses of immune globulin (on days 6 and 7), followed by measurement of muscle strength 2 days later (day 9). They receive additional IG infusions on days 13, 20, and 27. A final set of tests is performed on day 29. Patients may leave the hospital on pass when no studies are being done. A patient's initial evaluation includes: * History and physical examination, neurological examination, eye examination * 24-hour urine collection * Blood tests on two separate days * Photographs showing the extent of muscle affected * Chest x-ray, electrocardiogram (EKG), and echocardiogram * Two muscle biopsies, one before and one after the IG treatments. For this procedure, a small sample of muscle tissue is surgically removed for examination under the microscope. * Muscle strength and endurance testing, including the following: The patient uses pulleys attached to machines that measure the strength of 24 different muscle groups The patient walks for 6 minutes and performs exercises To evaluate swallowing, the patient swallows a thick substance called barium The patient's tongue strength is measured using a specialized instrument. -Magnetic resonance imaging (MRI) of the muscles of the thigh or calf: MRI uses a magnetic field and radio waves to produce detailed pictures of organs and tissues. During the scan, the subject lies on a table in a narrow cylinder containing a magnetic field, wearing ear plugs to muffle loud noises that occur with electrical switching of the magnetic fields. He or she can speak with a staff member via an intercom system at all times during the procedure. The neurological and muscle strength and endurance evaluations are repeated on study days 9 and 29.
NCT00656903
This study will use an eye imaging test called high speed indocyanine green angiography (HS-ICG), which examines leaky vessels in the eye, to try to find out why individuals respond differently to ranibizumab (Lucentis) treatment for wet age-related macular degeneration (AMD). The drug was recently approved by the Food and Drug Administration to treat this disease, but the response to the treatment varies markedly among individuals. People 50 years of age and older with wet AMD and vision that meets the research protocol criteria may be eligible for this study. Participants undergo the following procedures: Ranibizumab injections in the study eye once a month for 4 months. Additional injections are given only if the study eye shows signs of bleeding or leaking fluid. The eye is numbed before the injection and the eye area is cleaned with an antiseptic. Antibiotic drops are used for 3 days following the injection to prevent infection. Clinic visits once a month for 2 years for evaluations to monitor the response to treatment. The evaluations may include the following examinations and tests: * Eye examination with dilation, optical coherence tomography and photography: The examination measures visual acuity, thickness of your retina (the back of the eye) andeye pressure. Bright lights will also be used so that the doctor can see the back of your eye. Photographs of the eye may be taken. * Fluorescein angiography to examine the blood vessels in the eye: A dye called fluorescein is injected into a vein in the arm. The dye travels through the veins to the blood vessels in the eyes. A camera takes pictures of the dye as it flows through the blood vessels. This test is done eight times during the study. * Indocyanine green angiography to examine the blood vessels in the eye: The procedure is the same as for fluorescein angiography, but it uses a dye called indocyanine green. This test is done once a month for the first year of the study and then every 3 months.
NCT02242448
Background: \- Computed tomography (CT) scanning is a procedure that helps doctors with diagnoses. It uses X-ray radiation to produce an image in three dimensions. Researchers want to study how to get the best quality CT scans using the lowest possible radiation dose. Objective: \- To determine how to improve CT scanning. Eligibility: \- Adults 45 years of age and older who have not had a CT scan in the past year and do not have kidney disease. Design: * Participants will be screened with a medical history and blood and urine tests. * Nurses will put an intravenous (IV) line into an arm or hand vein. It will stay in for several hours during the magnetic resonance imaging (MRI) and CT scans. Through this IV, blood will be taken, dye will be injected, and medicine will be given. * Participants may have a CT scan of the heart, head, chest, abdomen, and/or pelvis. Participants will lie on their back on a table. The table will slide into a donut-shaped machine. An X-ray tube will move around the body, taking pictures. * Participants may be given a drug called a beta blocker by mouth or through the IV tube. * Participants heart rate and blood pressure will be monitored. * Participants may have an MRI scan. The MRI is a large hollow tube. The participant will lie on a table that will be moved into the tube, which contains a magnetic field. When the imaging starts, a thumping sound will be heard. Headphones or earplugs will be provided to muffle the sound. * Participants will give blood samples.
NCT00025857
The purpose of this study is to use brain imaging technology to examine the brain activity of adolescents with post-traumatic stress disorder (PTSD) and/or major depressive disorder (MDD) before and after treatment. Adults with PTSD or MDD exhibit abnormalities in the structure and function of certain parts of the brain. Although PTSD and MDD are psychiatric disorders that often emerge in childhood, the relationship between these disorders and brain structures has not been thoroughly studied in adolescents with the disorders. This study will use functional magnetic resonance imaging (fMRI) to study the parts of the brain that are involved in PTSD and MDD in adolescents. Adolescents with PTSD and/or MDD will be enrolled along with healthy adolescents with or without a history of abuse. Healthy adults will also be enrolled. Participants will be screened with a physical examination; blood tests; and interviews about mood, general degree of nervousness, and behavior. Adolescents and their parents will be interviewed separately and together. Following the interviews, participants will undergo psychological tests. Participants with PTSD and/or MDD will have two weekly sessions of talk therapy. Participants who continue to experience PTSD or MDD symptoms after the talk therapy may continue the talk therapy alone, begin treatment with fluoxetine (Prozac ) alone, or begin fluoxetine in addition to the talk therapy. Participants who take fluoxetine will have blood collected before treatment and 8 weeks after treatment has begun. If participants do not respond to the treatment, the treatment will be stopped and the participants will be offered another treatment. Participants who respond to treatment will continue treatment at NIH until a referral to an outside physician is made. Depending on the experiment in which they are enrolled, participants will undergo one or four MRI scans. Participants who will have four MRI scans will undergo the scans on separate days. During the MRI, participants will complete tasks on a computer. Saliva samples will be collected before and after the scans. Participants with PTSD and/or MDD will collect their saliva one or two days before the MRI scan.
NCT01492933
Background: \- Studies show that alcohol changes the amount of many brain chemicals. These changes may be related to continued drinking, craving for alcohol, and relapse. This study will use magnetic resonance imaging (MRI) to look at brain areas and brain chemistry during an infusion of alcohol. It will also study how changes in brain chemistry relate to participant reports of feeling drunk. Objectives: \- To use magnetic resonance imaging to measure the effect of alcohol on brain chemistry Eligibility: * Individuals between 21 and 45 years of age. * Participants will be either light drinkers (1 to 14 standard alcoholic drinks per week) or heavy drinkers (20 to 40 standard alcoholic drinks per week). A standard drink is a 12-ounce beer, a 4-ounce glass of wine, or a shot of liquor. * Participants must be able to go without alcohol for at least 3 days in a row without severe withdrawal symptoms. Design: * This study requires two or three outpatient visits to the NIH Clinical Center. * Participants will have a physical exam and medical history. Blood and urine samples will be collected. Participants' alcohol drinking habits will also be assessed to determine whether they may have an alcohol use disorder. * At the first study visit, participants will have an infusion of alcohol. Blood samples will be collected to measure blood alcohol levels. * The MRI study visit will take place about 3 days after the first study visit. Participants will have an MRI scan of the brain, followed by an infusion of alcohol and another scan. Blood samples will be collected. * Participants will complete questionnaires before and after each infusion to measure their response to alcohol. * Heavy drinkers will come to the clinic for a third visit to discuss possible future treatment and any risky behavior associated with their high levels of alcohol use.
NCT02141503
Background: \- Alpha-mannosidosis is a rare inherited disorder. It causes problems in many organs and tissues of the body. It can occur in children and adults. Because there is no treatment for this disease, researchers want to find out more about it. Objective: \- To learn more about Alpha-mannosidosis. Eligibility: \- People ages 5-60 with Alpha-mannosidosis. Design: * Participants will be recruited from patient support organizations and medical genetics clinics. * Participants will have 3 study visits, about once a year. A final evaluation will be made after 3 years. * Participants will have a medical history and a physical exam. * Blood samples and a urine sample will be collected. * Cerebrospinal fluid will be collected. A small area of the lower back will be numbed with medicine. A thin needle will be inserted between the spine bones. About 2 tablespoons of spinal fluid will be removed. * Brain magnetic resonance spectroscopy (MRS) scans will be done at each visit. MRS uses a strong magnetic field and radio waves to take pictures of chemicals in the brain with a scanner. The participant will lie on a table that can slide in and out of the cylinder. While in the scanner the participant will hear loud knocking noises. They will get earplugs or earmuffs to muffle the sound. Medicines might be used to keep the participant asleep during the MRS. * Participants will have a skin biopsy at the first visit only. A small area of the participant s skin will be numbed. A small circle of skin will be removed with a biopsy tool.

NCT02270944
The purpose of the present study is to assess and compare in healthy non-pregnant women 18 to 40 years of age the safety and immunogenicity of a liquid formulation of Group B Streptococcus (GBS) Trivalent Vaccine (not requiring reconstitution prior to administration), and of the lyophilized formulation of GBS Trivalent Vaccine, administered in non-pregnant and pregnant women in the clinical development program to date.
NCT01328613
Background: \- Postpartum depression (PPD) is a serious syndrome that resembles a major depressive episode and occurs in 10% to 20% of all mothers in the year following delivery. Women with histories of major depressive disorder (MDD) are at an increased risk for PPD and recurrent PPD with subsequent pregnancies. One possible genetic vulnerability to depression and PPD in particular is the BDNF gene. BDNF is a protein that affects the growth and development of brain cells, including those that help to regulate mood. BDNF levels have been shown to be significantly lower in individuals with depression, including women. Researchers are interested in studying BDNF levels and hormones such as estrogen in pregnant women who have MDD and are at risk for developing PPD. Objectives: \- To study connections between the BDNF protein and hormonal levels in pregnant women who are at risk for developing postpartum depression. Eligibility: \- Women who are currently pregnant and have a history of major depressive disorder, and either are taking a selective serotonin reuptake inhibitor (SSRI) or are not taking an antidepressant. Design: * This study involves six visits over the course of 12 months, during the first, second, and third trimesters (if possible) as well as 1 week, 1 month, and 3 months postpartum. Women will be allowed to participate at any point during pregnancy, but researchers are most interested in recruiting women who are in the first trimester. * Participants will be screened with a physical examination and medical history, blood samples, and questionnaires about their history of depressive episodes. * At each visit, participants will complete a number of questionnaires on depression symptoms, such as sleep disturbance and stress levels. Participants will also provide blood samples for hormone and other testing. * Participants who become depressed during the study will be referred to a treating psychiatrist or other professional for appropriate care and treatment.
NCT00805285
The purpose of this study is to evaluate if the combination of oral budesonide and rectal hydrocortisone improves symptoms in patients with active ulcerative colitis. Also, we would like to determine if oral budesonide and rectal hydrocortisone has fewer and less severe side effects compared to standard steroids (prednisone).
NCT01352286
The purpose of this study is to 1) evaluate the safety and tolerability of autologous genetically modified T cells transduced to express the high affinity NY-ESO-1c259 TCR in HLA-A2+ subjects and 2) measure the incidence of GVHD in patients following infusion of TCR modified autologous T cells.
NCT02135692
This is a multi-center, open-label, long-term study of subcutaneously (SC) administered mepolizumab 100mg in addition to standard of care (SOC), in subjects with severe eosinophilic asthma. This study will enroll a subset of subjects from Study MEA115661 who have demonstrated clear benefit from therapy and who without continuation of mepolizumab therapy are individuals at greatest risk of serious deterioration of their health status. In order to target individuals at greatest risk for serious deterioration of their health status, only subjects from the MEA115661 study with a history of life-threatening or seriously debilitating asthma, will be allowed to participate. Subjects meeting all of the eligibility criteria for the study will be offered the opportunity to consent for this study of up to 128 weeks in length (including the Follow-Up Visit). This study will give opportunity to extend the collection of clinical data for long-term use and further assess the sustainability of efficacy in a population likely to experience significant loss of asthma control and the need for higher doses of systemic steroids if returned to SOC only.
NCT02904278
The purpose of this study is to collect and compare information on how and when adolescent heart transplant recipients take their prescribed medication. The investigators want to find out if regular use of 'an app' on cell phones, called the Teen Pocket PATH® (TPP), can help adolescents take their medication according to their prescribed dosing schedule. This may then help reduce complications of transplant, such as rejection. The investigators also want to find out if how adolescent heart transplant recipients take their medications affects the development of antibodies in their blood. Antibodies are small proteins in the blood that may develop after heart transplantation, and which can sometimes damage a new heart.
