Ali Calikoglu, MDAli Calikoglu, M.D

Professor of Pediatrics
Division of Pediatric Endocrinology and Diabetes

In 1982, he received his doctorate in medicine from Ankara University in Turkey. He completed his residency in pediatrics at Hacettepe University, Ankara, Turkey. He then served as instructor in pediatrics at Hacettepe University. Upon arrival in the United States, he pursued a fellowship in pediatric endocrinology in the Department of Pediatrics at UNC, Chapel Hill. Since he finished his fellowship, he has been a faculty at the same institute. He served as Division Chief between 2008 and 2013.

Dr. Calikoglu has been honored with the Turkish Physicians Foundation Award, the Clinical Investigator Award from the National Institutes of Health/National Institute of Diabetes and Digestive and Kidney Diseases. He is a member of the Society for Pediatric Research, Pediatric Endocrine Society, and Endocrine Society. He has published over 70 peer-reviewed articles, books and book chapters in his areas of interest, namely regulation of IGF-I system proteins in developing mammalian brain, vitamin deficiency and growth disorders in pediatric endocrinology and pediatric/adolescent diabetes.

He is co-leading the effort to develop a specialized, multi-disciplinary clinic for patients with Differences of Sex Differentiation (DSD). This group includes specialists from Pediatric endocrinologists, pediatric urologists, pediatric surgeons, child psychiatrists and psychologists, neonatologists, general pediatricians and ethicists. The group has developed a management protocol for best practice guidelines for UNC and established the multi-disciplinary clinic. This clinic is the only such a clinic in NC and surrounding states, and fulfills a great need for comprehensive and multidisciplinary management of individuals with DSD.

He has involved in both investigator-initiated studies and multi-center clinical trials that are funded by NIH, non-profit foundations (i.e. JDRF) and industry.

The investigator initiated studies have primarily focused on pediatric diabetes. In collaboration with a diabetes center in Turkey, he has demonstrated that the symptom spectrum of hypoglycemia extends beyond adrenergic and neuroglycopenic symptoms and includes behavioral and psychosensorial symptoms. In another study, he showed that diabetic ketoacidosis acutely leads to a special spatial memory defect, which may be contributing to the long-term cognitive deficits observed in patients with diabetes mellitus. The second arm of study that investigates potential affected pathways in CNS is currently ongoing.

He is the principal investigator of TrialNet at UNC which is an NIH-supported multicenter trial exploring natural history of diabetes and testing new strategies that would prevent or delay the progression of diabetes in high-risk populations. Similarly, he has involved in clinical trial from another NIH-supported multi-center group, Type 1 diabetes EXCHANGE. He has participated several industry-sponsored clinical trials on pediatric GH deficiency, Growth hormone insensitivity syndrome and pediatric type 1 diabetes.

He has worked with fellows in diagnosing and defining the gene mutations causing rare diseases including thiamine responsive megaloblastic anemia syndrome, delayed puberty caused by a mutation in the gene encoding FSH beta chain, familial hypocalciuric hypercalcemia, Schwachman-Diamond syndrome, Hb-Raleigh and vitamin D dependent rickets type 1.

I was born and bred a Floridian, but have lived in the Durham- Chapel Hill area for 10+ years with my husband and three children. I was first REALLY introduced to diabetes during my fourth year of medical school. I was going off to a regional Diabetes Camp as the senior in-cabin counselor for 10 preteen girls with insulin dependent diabetes. I felt confident. I had studied blood sugars and insulin and knew the mechanism of action of drug therapy. I had even worn an insulin pump. But hours into camp I realized that studying diabetes was not KNOWING diabetes. As I lived and breathed with these children, I realized that children will be children, no matter what is thrown their way, and my ultimate role would be to understand who these children were despite their diabetes.

I originally came to UNC as a fellow in Pediatric Endocrinology and stayed on as faculty. My research interests currently focus on clinical diabetes care and the transition of care from adolescence to adult-based medicine for patients with chronic conditions.
