Are you an adult female with LAM? If so, you may be able to participate in this clinical study where researchers are observing patients who are taking or have taken a certain kind of medication, mammalian target of rapamycin (mTOR), to treat lymphangioleiomyomatosis, also known as LAM. You must be at least 18 years old to take part. The study is taking place at locations in California, Colorado, Florida, Georgia, Illinois, Massachusetts, Michigan, Minnesota, Missouri, New York, Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, and Washington.

Do you or your child have a platelet, bleeding, or white blood cell disorder? This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

Does your infant have a low platelet count? This study is investigating the safety and efficacy of platelet transfusion as a treatment for infants with thrombocytopenia. Researchers are looking at the positive effects of platelet transfusion against the negative effects, such as the release of inflammatory molecules and the formation of blood clots. To participate in this study, your child must be younger than 6 months old and have a low platelet count (less than 100 × 109/L). This study takes place in Boston, Massachusetts.

Does your infant have a low platelet count? This study investigates immature platelet counts as a marker for bleeding risk in newborns with thrombocytopenia, compared with platelet counts alone. Immature platelets are the most recently produced platelets and may be a better marker of platelet production. To participate in this study, you must have a newborn who is less than 32 weeks’ gestational age, has a birth weight greater than 500 grams, and has a platelet count less than 100 × 109/L. This study takes place in multiple locations in the United States, the Netherlands, and Sweden.

his trial will evaluate an oral drug discovered in a high throughput screen, which increases fetal globin protein (HbF and red blood cells expressing HbF)and messenger ribonucleic acid (mRNA) to high levels in anemic nonhuman primates and in transgenic mice.

Sickle Cell Disease (SCD) impairs oxygen transport to tissue and causes endothelial injury. Thus, therapeutic interventions aim to improve both, but there is an unmet need for biomarkers to determine when intervention is necessary and evaluate the effectiveness of the chosen intervention in individual patients. This study proposes to monitor SCD and its treatment through their impact on cerebral hemodynamics, as the brain is one of the most vulnerable and consequential targets of the disease. Specifically, this study will optimize quantitative magnetic resonance imaging (MRI) and advanced optical spectroscopy techniques such as frequency-domain near-infrared and diffuse correlation spectroscopies (FDNIRS-DCS) to monitor 1) cerebral oxygen transport with measures of cerebral blood flow (CBF), cerebral oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen consumption (CMRO2) and 2) endothelial function with cerebrovascular reactivity (CVR).

Are you 15 to 40 years old and have severe sickle cell disease? This study is comparing long-term outcomes for patients who receive blood and bone marrow transplants and those who receive standard treatment with medicines. Participants also have an option of contributing blood samples to be stored for future research. Participants must be 15 to 40 years old and have severe sickle cell disease. This study is located in Madison, Wisconsin.

Are you an adult who has sickle cell disease and wheezing not caused by asthma? This study will test an inhaled medicine called mometasone for people who have sickle cell disease and wheezing that is not caused by asthma. To participate in this study, you must be at least 18 years old and not have asthma, acute respiratory symptoms, or a current pain crisis. This study is located in New York, New York.
