Profile: Dr. William Sandborn, New Chief of Gastroenterology

DrWilliamSandborn_160x200“We’re open for business,” smiled Dr. William Sandborn, UC San Diego’s new Chief of Gastroenterology.

He has launched his clinics and plunged into his administrative roles. He is assembling teams to conduct clinical trials of potential treatments for inflammatory bowel disease (IBD), in which he is an internationally esteemed clinician and researcher.

William J. Sandborn Jr., MD, comes to UC San Diego from the Mayo Clinic in Rochester, Minnesota, where he was Dorothy A. Adair Professor of Medicine, vice chair of the Mayo Clinic Division of Gastroenterology and Hepatology, and associate dean of research for Intellectual Property and Industry Relations.

He sees the possibilities here as limitless.

“Gastroenterology at UC San Diego is at the beginning of a period of great change that I think will be very positive,” he said, “with the expansion of the clinical enterprise over the next five years that includes a dramatic extension of UC San Diego Health System’s La Jolla campus.”

“It is a really exciting time to be here,” he said.

“We’re coming together across departments to create service lines
to address the unmet needs of our patients.”

Patient Care: Growing to Meet More Needs

Gastroenterology is significantly expanding its patient care capabilities by drawing on UC San Diego’s institutional strengths and establishing key new efforts in transplantation, liver cancer, non-alcoholic steatohepatitis, and viral hepatitis, Sandborn said.

“We have fabulous multidisciplinary teams,” he said. “We’re coming together across departments to create service lines to address the unmet needs of our patients.”

There are strong partnerships with the Departments of Surgery and Radiology, among others. The new Center for Hepatobiliary Disease and Abdominal Transplantation (CHAT), co-directed by Robert G. Gish, MD, and surgical professor Alan Hemming, MD, MSc, is one of many programs that will be important, Sandborn said.

Dr. Gish, an internationally respected liver specialist who joined the Gastroenterology faculty late last year, is the new chief of clinical hepatology and director of the Liver Center.

Other major clinical efforts include the Gastrointestinal Endoscopy program, headed by Dr. Tom Savides, and Sandborn’s own clinics for inflammatory bowel disease (IBD).

Sandborn will lead UC San Diego Health System’s Inflammatory Bowel Disease Center, a new multidisciplinary clinical effort designed to serve the estimated 15,000 individuals in San Diego County who suffer from IBD.

IBD is the collective term for inflammatory conditions of the colon and small intestine. The most common types of IBD are ulcerative colitis and Crohn’s disease. Although there is a genetic predisposition to developing IBD, there is no known cause or certain cure. Treatment requires lifelong medical care for many sufferers and involves the suppression of the body’s abnormal inflammatory response. Ulcerative colitis may be surgically curable as it is limited to the colon. Although Crohn’s disease is not curable, some patients may also benefit from surgery.

According to the Greater San Diego and Desert Area Chapter of the Crohn’s and Colitis Foundation of America, the local IBD prevalence rate is approximately one in 200 people. The actual number of those affected could be higher, as the symptoms of IBD often overlap with those of other disorders.

UC San Diego Health System’s IBD Center is a collaboration with surgeons Mark Talamini, MD (Chief of the Department of Surgery), Sonia Ramamoorthy, MD, and Lisa McLemore, MD, in the Division of Colorectal Surgery. In addition to Dr. Sandborn, the Center’s gastroenterologists include Michael Docherty, MD, and Derek Patel, MD, who have advanced subspecialty training in IBD.

Surgeon’s Son Planned to Follow in Father’s Footsteps

Sandborn received his gastroenterology fellowship training at the Mayo Clinic after completing his medical school training, internship, and internal medicine residency at Loma Linda University in Loma Linda, California.

He joined the faculty of the Division of Gastroenterology and Hepatology at the Mayo Clinic when he completed his fellowship there in 1993.

As a youth, he observed surgeries, joined his father on rounds

The son of a general surgeon, Sandborn had the opportunity to see the practice of medicine up close when he was in his youth. He observed surgeries and went along on his father’s rounds from time to time, and he initially intended to become a surgeon himself.

During the gastroenterology rotation in his internal medicine residency training at Loma Linda University, he discovered a deep interest in gastroenterology.

He chose the subspecialty for its blend of diagnosis, pharmacology, and patient care; he enjoys both the technical side and the human side of his work, he said.

Because inflammatory bowel disease tends to occur early in life, many of his patients are young when they first come to see him. They grow up, enter college, start their families, and start their careers as he manages their treatment.

“I get to see them go through the years,” Sandborn said.

He often becomes his patients’ main doctor, serving in a sense as a classic primary care physician but with the specificity and cutting-edge technology of gastroenterology practice.

“In IBD,” he said, “we suppress the disease chronically, and we are able to achieve increasingly good outcomes in our patients. We don’t cure because we don’t yet know the causes of the disorders.”

Through clinical trials, Sandborn works to make new IBD treatments available

Because he is a clinician who is also a longtime clinical trials researcher, he sometimes has the chance to see his own patients benefit from drug treatments he has been involved in developing. “That is a privilege,” he said, “that not very many people have.”

And, as it turns out, he practices in a field where internal medicine and surgery overlap. “IBD patients sometimes need surgical care as well as management with pharmacological treatments,” he said. “I get to do a little bit of everything.”

UCSD: “Fantastic Research Capabilities and a Wealth of Experience”

Sandborn is widely respected for his research in the pharmacological treatment of IBD. He has designed and directed many clinical trials of current and potential future IBD treatments and has published more than 350 scholarly articles in major journals. In 2010, he was honored with the Scientific Achievement in IBD Clinical Research Award from the Crohn’s and Colitis Foundation of America.

He sees excellent research opportunities here at UC San Diego.

“There are fantastic research capabilities and a wealth of experience in the Department of Medicine and the other departments and schools as well as in the research institutes and the biotechnology companies in the surrounding area,” he said.

He pointed to recent major developments in research at UC San Diego, among them the Clinical and Translational Science Award to Dr. Gary Firestein for the Clinical and Translational Research Institute.

Sandborn expects to begin his own clinical trials here in the second quarter of this year. He will be studying several biologic therapies designed to intervene in the chronic inflammation of IBD by blocking integrins and thereby preventing white blood cells from migrating to inflamed tissues in the intestinal wall.

He will also study specific monoclonal antibodies as potential treatments for Crohn’s disease. These compounds target the T-cell proinflammatory cytokines interleukin (IL)-12 and IL-23.

Continuing a Tradition of Leadership

As Gastroenterology chief here, Sandborn hopes to be a leader in the tradition of his mentors at Mayo Clinic and elsewhere. “Drs. Nick LaRusso, Keith Lindor and Greg Gores are excellent, inspiring, visionary leaders,” he said, naming three successive chiefs of the Division of Gastroenterology and Hepatology at the Mayo Clinic.

Two others played particularly significant roles in shaping his career. “Drs. Stephan Targan at Cedars-Sinai Medical Center in Los Angeles and Stephen B. Hanauer of the University of Chicago had a big impact on me, even though we were not at the same institution,” he said.

In recognition for his own efforts as a mentor, Sandborn received the Outstanding Mentor Award from the Department of Medicine at the Mayo Clinic in 2010.

Sandborn is an elected Fellow of the American College of Physicians (1996), the American College of Gastroenterology (1998), and the American Gastroenterological Association (2008).

He has held numerous positions on extramural committees, the most recent including the Immunology, Microbiology, and Inflammatory Bowel Disease Section of the American Gastroenterology Association (chair, 2006-2008); the AGA Institute Future Trends Committee (member, 2007-2009); the Inflammatory Bowel Disease Working Group of the National Commission on Digestive Diseases (member, 2007); and the International Organization of Inflammatory Bowel Disease (chair, 2008-2010).

Moving Ahead With the Leadership of Interim Chair Wolfgang H. Dillmann, M.D.

Wolfgang Dillmann, MDWolfgang H. Dillmann, MD, a respected division chief and internationally recognized physician-scientist, assumes leadership of the Department of Medicine this week as Dr. Ken Kaushansky departs for his new position as Senior Vice President for Health Sciences and Dean of the School of Medicine at Stony Brook University in New York.

“Wolf has made major contributions to the Department of Medicine for decades, in the realms of science, teaching and clinical care,” said Dr. Kaushansky.

“Now, by taking on the challenging role as interim Chair, he will make even greater contributions to the students, residents, fellows and faculty who call the department home.”

Dr. Dillmann, Professor of Medicine and Chief of the Division of Endocrinology and Metabolism, has served the Department for many years in positions on the Finance Committee and the Space Committee.

Dr. Joe Witztum, Professor of Medicine and Dr Dillmann’s longtime colleague in the division, described him as a dedicated and thoughtful leader, a superb clinician, and a true physician-scientist. “I’m not surprised that he was asked to be Interim Chair,” he said.

Dr. Tom Savides Named Executive Vice Chair

New positions in the Department of Medicine leadership team will support Dr. Dillmann in his interim role. Dr. Tom Savides, Professor of Clinical Medicine and Interim Chief of the Division of Gastroenterology, will serve as Executive Vice Chair.

Dr. Savides also holds the positions of Clinical Service Chief for Gastroenterology, Director of the Gastroenterology Fellowship Program, and Director of Advanced GI Endoscopy.

Dr. Richard Gallo, Professor of Medicine and Pediatrics and Chief of the Division of Dermatology, will serve as Vice Chair for Laboratory Research and co-chair, with Dr. Robert Schooley, of the department’s Space Committee.

Dr. Schooley, Professor of Medicine and Chief of the Division of Infectious Diseases, will continue as Vice Chair for Academic Affairs.

As before, Drs. Elaine Muchmore, Dan Bouland, Francis Gabbai and Ravi Mehta will serve as the vice chairs for Education, Clinical Operations, VASDHS Affairs, and Clinical Research, respectively. Maureen O’Connor is Vice Chair for Administration.

About Dr. Dillmann

“Wolf is an old-fashioned physician-scientist,” said Dr. Witztum, who joined the faculty within months of Dr. Dillmann in 1979. “In the old days, we used to talk about the ‘triple threat’ – physician, scientist, and teacher. It’s hard to do all three, particularly these days, and Wolf still really does it well.”

In his clinical activities, Dr. Dillmann specializes in endocrine diseases, especially thyroid disease. His research activities are directed at endocrine and metabolic influence on cardiovascular function.

Over the years, he has maintained a deep involvement in clinical work despite the expansion in his other roles. “He’s a superb endocrinologist and internal medicine doctor,” Dr. Witztum said.

“He’s dedicated to providing good clinical services,” he said. “He works very hard to develop clinical programs, particularly for the care of diabetic and metabolic syndrome patients.”

In recent months, Dr. Dillmann has led the division through a successful recertification of the Endocrine Fellowship Training Program. He is an active teacher in the Department of Medicine’s core courses in the School of Medicine and he serves as mentor for postdoctoral fellows and medical students.

Dr. Dillmann’s research focused initially on thyroid disease and its effects on heart function. His work has expanded in recent years to examine the biochemical and cellular properties of heart cells and the ways in which they are affected by thyroid hormone and glucose metabolism.

“He has become an international expert on cardiac metabolism in general,” Dr. Witztum said. “His studies are of interest not only to endocrinologists but also to cardiologists who are interested in the basic mechanisms by which the heart works.”

Dr. Dillmann is a member of the Diabetes and Endocrinology Research Center (DERC), the Institute of Engineering in Medicine, and the Cardiac Mechanics Research Group at UCSD.

He serves as reviewer for a number of major scientific journals including the Journal of Clinical Investigation, Endocrinology, American Journal of Physiology, the Journal of Biological Chemistry, Circulation, and Circulation Research.
