Doctor at Johns Hopkins All Children’s Leads Groundbreaking Research
St. Petersburg, Fla. – October 26, 2017 – Jennifer Leiding, M.D., a pediatric immunologist and allergy specialist at Johns Hopkins All Children’s Hospital and associate professor of pediatrics at USF Health Morsani College of Medicine, led a global study on a rare and often deadly type of immune dysregulation disorder. This study, published in The Journal of Allergy and Immunology, resulted in new research which could set the stage for life-saving treatments in the future.
Dr. Leiding’s accurate diagnosis of a young patient who had suffered with a mysterious illness prompted her to begin the study. Once the patient was confirmed as having a rare mutation in his immune system, called STAT1 Gain of Function (GOF-STAT1), Dr. Leiding began collaborating with specialists around the world who had treated patients with the same rare diagnosis who had undergone hematopoietic stem cell transplants. The researchers learned that bone marrow transplant as a potential therapy for GOF-STAT1 had not been studied.
“We are only beginning to understand how this mutation impacts patients’ immune systems, and what treatments and modalities can make a difference for them,” says Dr. Leiding. “More research in this area can surely help solve this puzzle.”
The findings reveal that while the risk is high, in some patients the transplant can provide a cure. The group of researchers hope to launch more in-depth studies later this year. Investigators are initiating a much larger prospective study to understand the strategy of transplant in patients with this rare disease and others like it.
