Pediatric Endocrinology

Pediatric Endocrinology

The Division of Pediatric Endocrinology maintains a tradition of excellence in research and clinical care related to endocrine disorders of children from throughout Kentucky and southern Indiana.

While the division has a strong background in growth disorders and diabetes, we have balanced interests and expertise in the full spectrum of pediatric, neonatal and adolescent endocrinology.

Through our Norton Children's Endocrinology practice, we provide diagnostic and therapeutic services for children with diabetes mellitus, metabolic diseases and disorders of physical growth, sexual maturation, thyroid function, adrenal function, pituitary function, and calcium and phosphorous metabolism.

We provide diagnostic endocrine tests for patients in the areas of endocrinology and carbohydrate, amino acid, and mineral and lipid metabolism.

We can also address growth abnormalities and the range of conditions that can cause them.

Nutritionists offer consultative and follow-up service for children up to 18 years of age with nutritional problems associated with abnormal food intake or chronic medical problems. Services provided: Diabetes nurse available for phone consultations five days a week and the services of two dedicated diabetes educators.

There are seven board-certified pediatric nurse practitioners specializing in endocrinology and diabetes on staff as well.

Joint Appointments


Lu Cai, MD, PhD
Professor of Pediatrics
Division Chief, Pediatric Research Institute
Divisions of Pediatric Research and Radiation Oncology, Pharmacology & Toxicology

Dr. Lu Cai received his MD in 1983, and Ph.D. in 1990 from Norman Bethune University of Medical Sciences (Currently Jilin University), Changchun, P.R. China. He was trained as a Postdoctoral fellow in Department of Pathology at University of Western Ontario in 1993 - 1995, and Department of Pharmacology and Therapeutics, McGill University in 1995 - 1996, Canada.  He is currently a tenured Professor, with appointments in the departments of Pediatrics, Radiation Oncology and Pharmacology, and Toxicology. In 2013, Dr. Cai was appointed as Director of Pediatric Research Institute, the University of Louisville School of Medicine. Lu Cai’s research interests include three major fields: (1) the hormesis and adaptive response induced by low dose radiation, and its potential clinical application; (2) systemic and reproductive toxicology of environmental exposures such as radiation and heavy metals, and (3) cardiovascular complications of diabetes and/or obesity. In more than 260 peer-reviewed publications in many journals including J Am Coll CardiolCirculation, and Diabetes, Dr. Cai has significantly advanced knowledge of the unique biological effects of low-dose radiation, mechanisms driving the diabetes and diabetic complications, identified synergistic or additive effects of environmental exposure with Western-style or high fat diet on metabolic syndrome, and discovered novel preventive and/or therapeutic approaches to these diseases.

Pediatric Endocrinology Fellowship Program

The University of Louisville Pediatric Endocrinology Fellowship is an ACGME-accredited program which provides comprehensive clinical and research training in Pediatric Endocrinology. Section faculty is comprised of seven pediatric endocrinologists, two clinical psychologists and three basic science researchers. The division has a vibrant research unit with numerous ongoing studies in type 1 diabetes, type 2 diabetes and growth hormone therapy. The division also boosts a strong support team including nurse practitioners, diabetes educators, dieticians, growth hormone specialists and research nurses. The section recruits one new fellow each year. The inpatient training is based at Norton Children’s Hospital, and outpatient training is based at UofL Pediatric Endocrinology clinic and the Wendy Novak Diabetes Center.

Fellows gradually assume increasing clinical care responsibility during their fellowship training. The majority of the first year of training is devoted towards patient care as well as an introduction of basic research concepts. Fellows have the opportunity to participate in multiple specialty clinics throughout their training including metabolic bone disease clinic, high risk diabetes clinic (DART), disorders of sexual development (DSD) clinic, gender clinic, and cancer survivorship clinic. 

The second and third years of training are dedicated primarily to research. The fellow develops a research project with the support of an advisor who will assist in guiding the project to completion. The fellow may also choose to complete a master’s degree at UofL in clinical investigation, public health or business administration.

The fellow also actively participates in case discussions, lectures, grand rounds, and fellow core conferences throughout the three years of training.
