Dr. Lumpkin is a member of ACHRI's Pediatric Endocrinology and Diabetes Research Working Group, a collaborative effort among ACHRI and UAMS investigators who share a common interest in the study of Types I and II diabetes in children and adolescents. The group's objectives center on the development of strategies for prevention, treatment, and improved management of these diseases. Bone disease is now a recognized complication of diabetes, and Dr. Lumpkin has been instrumental in working with Dr. Kathryn Thrailkill, MD, and Dr. John Fowlkes, MD, to develop new techniques to study bone disease in diabetes. Using distraction osteogenesis, a method perfected by Dr. James Aronson, MD, Dr. Lumpkin and the diabetes team have begun to examine how insulin deficiency (Type I diabetes) and insulin resistance (Type II diabetes) impact on new bone formation. Currently, he is exploring treatments that may improve bone formation in both types of diabetes.

Dr. Lumpkin’s laboratory also investigates the effects of alcohol on bone formation. Epidemiological data suggest that skeletal pathology caused by excessive alcohol consumption may cost the US economy $2 billion annually. Patients with alcoholic bone disease display marked impairment in bone formation. The long-term goals of his research are to determine the biological mechanisms underlying this process and to explore therapeutic solutions.
