Research Efforts 

The team at the Comprehensive Center for Congenital Adrenal Hyperplasia (CAH) conducts basic science and clinical research. The shared goal of their efforts is to advance the treatment of CAH and improve the lives of people affected by it.

Current research efforts are aimed at:

  • Optimizing steroid dosing at all stages of a patient's life(during well periods as well as times of illness, stress, and injury).
  • Our physicians conduct a study that examines the appropriate doses of steroid replacement in children with CAH who undergo surgery. The study is actively enrolling patients.
  • Metformin therapy in addition glucocorticoid therapy in young girls with CAH. The study wants to determine if Metformin helps these patients achieve better hormonal control. It is waiting IRB approval.
  • Studying the long-term outcome of children with CAH who have obesity and insulin resistance. This study is now under development.
  • Assessing the psychological effects of CAH and its influence on quality of life and development. The study is actively enrolling patients.
  • Our investigators are also examining the roles of androgen receptors (AR) and estradiol receptors (ER) in genital development. They characterized AR and ER in the genital tissue of females with CAH. They found both AR and ER in erectile tissue from these patients, with a tendency toward higher AR expression in Prader 5 patients compared with Prader 4 patients. These results provide insights into the development of both AR and ER in genitourinary tissue. The results of additional studies may lead to pharmacologic intervention as an adjunct to CAH treatment.
