5 Clinical Trials for Various Conditions
The purpose of this study is to collect blood samples to enable validation of genetic testing for diseases within a multi-disease carrier screening panel. Samples will be collected from adult women or men who have previously tested positive as carriers for various recessive conditions. These are healthy adults who carry a mutation that might place them at increased risk of having a child with a specific genetic disorder. Study participation will be open to adults that were previously tested as part of their routine medical care and where test results demonstrated positive carrier status for a specific genetic disease. Samples will be tested for the disease mutation for which the subjects provides documentation of prior testing.
Sickle cell disease is a life-threatening genetic disorder that can be effectively treated following early diagnosis via newborn screening. However, sickle cell disease is most prevalent in low-resource regions of the world, where newborn screening is rare due to the cost and logistical burden of laboratory-based methods. In many such regions, \>80% of affected children die, undiagnosed, before the age of five years. A convenient and inexpensive point-of-care test for sickle cell disease is thus crucially needed. In this study we will conduct a blinded, multicenter, prospective diagnostic accuracy study of HemoTypeSC(TM), an inexpensive 15-minute point-of-care immunoassay for detecting sickle cell disease, hemoglobin C disease, and trait phenotypes in newborns, children, and adults.
The purpose of this study is to create a rapid scan of the pancreas and ovaries that could be used in the future to screen patients at risk for pancreatic or ovarian cancers. Currently, Magnetic Resonance Imaging (MRI) examinations of the pancreas and ovaries can last 30-45 minutes each. The investigators hope to create a rapid pancreatic and ovarian MRI evaluation that can be used as a screening tool that is completed in approximately 15 minutes. They will compare different tools available on modern MRI scanners to see which one reliably offers high quality images of the pancreas and ovaries.
Johns Hopkins clinical research office quality assurance group will monitor and audit this study at Johns Hopkins. The Sub Investigator at each site will be responsible for internal monitoring at their site.
The goal of this clinical research study is to compare ovarian cancer screening, risk-reducing salpingo-oophorectomy (RRSO), and prophylactic salpingectomy with delayed oophorectomy (PSDO). The safety of RRSO and PSDO will also be studied. Ovarian cancer screening does not involve a surgical procedure. Instead, physical exams, blood tests, and ultrasound are used to check for ovarian, fallopian tube, and peritoneal cancer. The surgical procedures, RRSO and PSDO, are designed to lower your risk of ovarian cancer. In RRSO, the fallopian tubes and ovaries are removed at the same time. In PSDO, the fallopian tubes are removed and the ovaries remain in place so that the patient does not go through menopause. The ovaries are removed at a later date. The main goal of this study is to learn how many patients actually have their ovaries removed at a later date. Researchers also want to learn whether the removal of fallopian tubes will decrease the risk of ovarian cancer.
