Featured Studies

Healthy volunteers 18-60 years old are needed to test an investigational drug that was developed to reduce blood pressure in the lungs. The PAH team from @NHLBI hope that this investigational study drug may be helpful in treating patients with PAH in the future.

Researchers are examining genetic and physical characteristics of the small vessel disease called CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy). They are enrolling volunteers to serve as healthy controls. Compensation is provided.

Doctors at the National Institutes of Health (NIH) are conducting a research study to determine the viability and safety of early initiation of oral therapy with cyclosporine and eltrombopag in patients with severe aplastic anemia (SAA).

A research study at the National Heart Lung and Blood Institute (NHLBI) is looking for pregnant women between 18 and 45 years of age who are at risk of having an infant with sickle cell disease and women who are pregnant with no risk of having an infant with sickle cell to donate their baby's cord blood. Tests and procedures provided at no cost. Travel may be reimbursed.

Pharmacologic therapy with Bruton's tyrosine kinase (BTK) inhibitors is associated with an increased risk of heart problems like atrial fibrillation, bleeding, and high blood pressure (hypertension) which can lead to sudden death. There is currently no standard for cardiac screening or monitoring patients on BTK inhibitors. Researchers at the National Heart, Lung, and Blood Institute (NHLBI) are investigating the relationship between the development of heart problems in patients on BTKi as it relates to other variables.

After stem cell transplantation, some people develop hard-to-treat anemia (low red blood cells) or thrombocytopenia (low platelets). Cytopenia(s) or low blood cell counts make you weak, prone to bleeding and bruising, and dependent on blood product transfusions. Researchers at the National Institutes of Health (NIH) are testing the drug fostamatinib to see if it is safe to treat cytopenia(s) after stem cell transplantation. A physician referral is not required to participate.

Researchers at the National Institutes of Health are investigating the role of Near-Infrared Spectroscopy (NIRS) technologies as a monitoring tool for measuring oxygen levels, blood flow, and the make-up of skin and muscle in patients with sickle cell disease (SCD). In this study, researchers will compare NIRS measurements in people with and without SCD.

Systemic lupus erythematosus (SLE) creates an imbalance in the innate immune system responsible for chronic inflammation. A study at NHLBI is looking into a Vitamin B supplement, nicotinamide riboside (NR), to see if it improves immune system function in people with SLE. People with SLE will be asked to take the supplement or placebo for 12 weeks. Healthy control subjects will be enrolled to compare baseline blood results but will not take the supplement.

Researchers at the National Heart, Lung, and Blood Institute in Bethesda, Maryland, are conducting a study to evaluate the airway immunity in adults with a positive TB skin or blood test. With this study, researchers hope to discover better prevention and treatments for TB. (En español)
