Jeffrey Lebensburger, MD

Dr. Lebensburger is a graduate of the University of Pennsylvania for undergraduate training and the Nova Southeastern Medical School. After his pediatric residency at Arnold Palmer Hospital for Children in Orlando, Florida, Dr. Lebensburger completed fellowship training in Pediatric Hematology Oncology at St. Jude Children's Research Hospital. His primary clinical focus involves caring for children with blood disorders, including sickle cell disease, thalassemia, bleeding disorders, disorders of iron metabolism, and marrow failure syndromes.

Sophie Lanzkron, MD, MHS

Dr. Sophie Lanzkron is an associate professor of medicine at the Johns Hopkins University School of Medicine. Her areas of clinical expertise include hematology and sickle cell disease. Dr. Lanzkron is director of the Sickle Cell Center for Adults at Johns Hopkins. Dr. Lanzkron received her undergraduate degree in biology from Brandeis University. She earned her M.D. from Albert Einstein College of Medicine. She completed her residency at the University of Maryland Medical Center and performed her fellowship in hematology at Johns Hopkins. She joined the faculty of Johns Hopkins in 2000. Dr. Lanzkron's major clinical research involves the study of sickle cell disease. Her primary research interest is to understand the barriers to care for adults with sickle cell disease. In 1998, the FDA approved the use of hydroxyurea to treat patients with sickle cell disease. This approval was based on a large clinical trial centered at Johns Hopkins. The use of hydroxyurea was predicted to decrease hospitalizations and the costs of care for those with sickle cell disease. Dr. Lanzkron's research has shown that despite the approval of hydroxyurea, the costs of caring for patients with sickle cell disease have increased significantly over the last seven years. Research is ongoing to identify the factors that limit access to care for this population.   Representative Publications: Efficacy and safety of ledipasvir/sofosbuvir for the treatment of chronic hepatitis C in persons with sickle cell disease Multiple Levels of Suffering: Discrimination in Health-Care Settings is Associated With Enhanced Laboratory Pain Sensitivity in Sickle Cell Disease Chronic Opioid Therapy and Central Sensitization in Sickle Cell Disease The Association of Clinician Characteristics with their Attitudes Toward Patients with Sickle Cell Disease: Secondary Analyses of a Randomized Controlled Trial Perceived discrimination in health care is associated with a greater burden of pain in sickle cell disease Venous thromboembolism in adults with sickle cell disease: a serious and under-recognized complication Dental infections increase the likelihood of hospital admissions among adult patients with sickle cell disease Online profile

Courtney Fitzhugh, MD

Courtney Fitzhugh received her B.S. magna cum laude from the University of California, Los Angeles in 1996, and her M.D. from the University of California, San Francisco in 2001. She is a member of the American Society of Hematology. Dr. Fitzhugh is exploring new avenues of hematopoietic stem cell (HSC) transplantation for sickle cell disease (SCD), while also studying the currently underexplored cardiovascular complications arising due to this genetic blood disorder. Dr. Fitzhugh is also conducting a half-matched protocol to increase the number of people eligible for HSC transplantation. The current procedure requires a fully HLA-matched sibling donor, and less than 20% of SCD patients would qualify. Dr. Fitzhugh is examining why SCD patients develop heart disease, and what can be done to prevent or possibly even reverse heart-related complications in this population. Through these joint avenues of research, Dr. Fitzhugh’s group is finding new avenues to help people with SCD live longer and healthier lives. Dr. Fitzhugh is also interested in learning more about death due to this disease.   Representative Publications: Losartan for the nephropathy of sickle cell anemia: A phase-2, multicenter trial Allogeneic hematopoietic stem-cell transplantation for sickle cell disease Relationship between Mixed Donor-Recipient Chimerism and Disease Recurrence Following Hematopoietic Cell Transplantation for Sickle Cell Disease Curative approaches for sickle cell disease: A review of allogeneic and autologous strategies Measurements of red cell deformability and hydration reflect HbF and HbA2 in blood from patients with sickle cell anemia Severe cardiac iron toxicity in two adults with sickle cell disease Do the Eyes Reveal More Than Scleral Icterus in Sickle Cell Disease?
