Francisco Sylvester, MD

Chief, Division of Pediatric Gastroenterology
Professor of Pediatrics

Endoscopy; colonoscopy; percutaneous gastrostomy; and percutaneous liver biopsy. Pediatric inflammatory bowel disease (Crohn's disease and ulcerative colitis).

Dr. Francisco Sylvester has a long-standing interest on the effects of chronic intestinal inflammation on growth, bone and muscle in children. His studies focus on children with inflammatory bowel diseases (Crohn’s disease and ulcerative colitis). He collaborates with investigators at UNC and across the country. His research has revealed that children with Crohn’s disease have significant deficits of bone mass and muscle mass at the time of diagnosis, and that these deficits largely persist 2-years post diagnosis, despite a decrease in symptoms and improved weight gain. Dr. Sylvester performs studies in human samples and in the basic science laboratory to arrive to mechanisms that explain these observations.

Matthew Egberg, MD, MPH, MMSc

Assistant Professor of Pediatrics

My clinical interests include pediatric Inflammatory Bowel Disease and improvements in the quality and reliability of care provision. In addition to completing fellowship training in pediatric Gastroenterology, Hepatology, and Nutrition, I have completed fellowships in both Quality Improvement, at the Institute for Healthcare Improvement, as well as Pediatric Health Services Research. My research includes studies of the clinical and comparative effectiveness of treatments for Inflammatory Bowel Disease (IBD) using real-world data to evaluate the risks and benefits of treatments used in everyday clinical practice.

Ajay S. Gulati, MD

Ajay S. Gulati, MD

Associate Professor of Pediatrics and Pathology & Laboratory Medicine

Pediatric inflammatory bowel diseases (Crohn's disease and ulcerative colitis); and intestinal epithelial repair responses in inflammation-induced gut injury.

Dr. Gulati’s lab is interested in understanding how the normal bacteria in the gut, known as the intestinal microbiota, can be used to improve the health of the intestines in patients with inflammatory bowel diseases (IBD).  To do this, Dr. Gulati and his research group study how the microbiota affects the function of different cells in the lining of the intestine.  The laboratory is particularly interested in a cell type knows as the Paneth cell, which produces natural antibiotics that protect the gut against infections.  This knowledge may help us learn new ways to manipulate to microbiota to treat IBD in a safe and effective manner, without the need for medications that suppress the immune system.

Michael D. Kappelman, MD, MPH

Michael D. Kappelman, MD, MPH

Professor of Pediatrics

Crohn's disease; ulcerative colitis; pediatric endoscopy and colonoscopy; clinical epidemiology; and health services research.

Dr. Kappelman’s research includes studies of the clinical and comparative effectiveness of treatments for Inflammatory Bowel Disease (IBD) using real-world data to evaluate the risks and benefits of treatments used in everyday clinical practice. He has received research funding from the NIH, AHRQ, PCORI, foundations, and industry. Selected examples of ongoing research studies include:

  • The largest pediatric Crohn’s trial in history to compare the effectiveness and safety of anti-TNF biologic agents (infliximab, adalimumab) used alone or in combination with a second immune suppressive agent (methotrexate).

  • A patient powered research network for children and adults with IBD that utilizes internet based recruitment and data collection to study the course of IBD through the eyes of patients and caregivers.

  • A study comparing the effectiveness and safety of 2nd line treatments for patients with IBD who did not respond to, or lost response to, anti-TNF.
