October 2007-National journal spotlights Dr. Fox's embryonic stem cell work

by Tom O’Connor, UNMC public affairs

 

Thanks in large part to the work of a UNMC scientist, an international group of researchers has demonstrated that embryonic stem cells can be converted into liver cells and used to restore liver function in mice with liver failure. The findings are reported in the Nov. 5 issue of Nature Biotechnology, the leading international science journal in the field.
 

Ira Fox, M.D., McLaughlin Professor of Surgery and senior associate dean for research in the UNMC College of Medicine, served as the senior author on the article and headed the study along with Naoya Kobayashi, M.D., Ph.D., of Okayama University Graduate School of Medicine and Dentistry in Japan.

 

In the study, the researchers generated liver stem cells from mouse embryos to help power a liver assist device in mice with acute liver failure. Typically, mice with acute liver failure die within a matter of days. However, using the liver assist device containing mouse liver cells derived from embryonic stem cells, 90 percent of the mice in the study experienced long-term survival.

 

After implanting the liver assist device seeded with the embryo-derived cells, the new cells developed characteristics nearly identical to those of primary hepatocytes (liver cells). The new cells filtered the blood much as the liver does, and kept the mice alive, while mice not fitted with the liver device died within two days.

 

The study was one of two articles in Nature Biotechnology this week that describe making liver cells from mouse embryonic stem cells. A research team at Mount Sinai School of Medicine in New York City headed the second study.

 

A third article in Nature Biotechnology, written by a San Diego research team, described an efficient method for converting human embryonic stem cells into cells that produce hormones made by the pancreas, a technique that could lead to a cure for diabetes.

 

“Both (liver) articles lay out a road map for how to regenerate a failed liver using embryonic stem cells,” Dr. Fox said. “The next step is to apply this approach to producing human liver cells.

 

“Our study is an important first step, but there’s still plenty of work to be done. Our work, and the other studies published this week, show we’re getting closer and closer (to making this applicable to humans).”

 

Embryonic stem cells are the body’s master cells and have the ability to transform into any kind of cell or tissue in the body.

 

Drs. Fox and Kobayashi have worked together for years on liver cell regeneration. Dr. Kobayashi worked at UNMC for two years completing his post-doctoral training under Dr. Fox during the late 1990s. In 2005, two UNMC research teams – one headed by Dr. Fox, the other by Stephen Rennard, M.D., Larson Professor of Pulmonary Medicine – received training on how to use human embryonic stem cells in research. Both groups brought human embryonic stem cell lines back to Nebraska for their research. The embryonic stem cell lines are among the stem cell lines approved by President Bush.

 

A liver transplant surgeon, Dr. Fox is trying to determine if embryonic stem cells can be safely turned into liver cells that would ultimately be infused into failing livers. This form of therapy, cell transplantation, could be used as an alternative to organ transplantation for some patients with liver failure.

 

Due to the shortage of organ donors to meet the increased demand for organ transplants, Dr. Fox has, over the past decade, examined a variety of alternative ways – other than organ transplantation – to regenerate damaged livers. During this period, Dr. Fox has also studied the properties of adult stem cells and pig liver cells for this purpose.

 

Infusing human liver cells into a diseased liver in 1997, Dr. Fox was the first to get transplanted individual liver cells to partially correct a rare metabolic liver disease in a 10-year old child. In doing so, the patient was able to avoid undergoing a liver transplant for many years. The research was reported in the New England Journal of Medicine in May 1998.

 

Currently, more than 17,000 Americans are on the waiting list for a new liver. Liver failure can be caused by viruses such as hepatitis, by drug or alcohol damage and by a range of other diseases. Often the only cure is a transplant, and more than 5,000 liver transplants are done in the United States each year.

New measures to enhance diversity, international medicine programs

by Tom O’Connor, UNMC public affairs

 
In an effort to strengthen and better utilize its resources in diversity and international medicine, UNMC Chancellor Harold M. Maurer, M.D., has announced a realignment of the Community Partnership Department as well as a change in the medical center’s international medicine initiative.

 

Ward Chambers, M.D., executive director of the Community Partnership Department, has been named interim coordinator of programs in international health and medical education. Dr. Chambers has extensive international experience and will play a key role in building upon the medical center’s many international partnerships, Dr. Maurer said.

 

The international program at UNMC and The Nebraska Medical Center has grown to more than 100 strategic global partners in 41 countries. Each year, the international program facilitates in bringing hundreds of international patients to UNMC for treatment as well as a significant number of international researchers, students and prominent speakers to Nebraska.

 

“With his strong background in medicine and diversity, Dr. Chambers will be a perfect complement to our already strong international programs,” Dr. Maurer said. “In his travels to Afghanistan and other foreign countries, Ward has been very successful in establishing links and providing assistance to people in need.”

 

In the realignment, those staff who have been involved in outreach and who have had liaison responsibilities with the North and South Omaha Community Care Councils will be assigned to the College of Public Health headed by Dean Jay Noren, M.D. Those staff who have been involved in multicultural affairs and diversity efforts will be assigned to Rubens Pamies, M.D., vice chancellor for academic affairs.

 

“Diversity is very important to our campus,” Dr. Pamies said. “We think this realignment will enhance the value of our diversity efforts and better utilize our resources so that we can more effectively deliver our services to the community. We think this will eliminate any possible redundancies and allow us to reassign resources in order to provide more services to the community.”

 

Dr. Noren said the employees assigned to the College of Public Health will work closely with David Grandison, M.D., Ph.D., who heads the college’s Center for Health Disparities.

 

“With change comes opportunity,” Dr. Noren said. “We’re excited to make these additions to our staff and think it will be a win-win situation for all of us.”

 

Linda Cunningham, staff diversity specialist for Human Resources, will assist Drs. Pamies and Noren in the restructuring.

UNMC co-sponsoring nursing conference in India

by Walter Brooks, UNMC public affairs

 

The first nursing conference in India co-sponsored by UNMC and The Nebraska Medical Center will be held in Mumbai, India, on Friday and Saturday.

 

The conference, which is a collaboration with P. J. Hinduja National Hospital and Nursing College, is organized and led by Nizar Mamdani, executive director of the International Healthcare Services (IHS).

 

Theresa Franco, service line executive director, cancer care, The Nebraska Medical Center; Kim Schmit-Pokorny, nurse manager/case manager; and Marcel DeVetten, M.D., assistant professor, UNMC’s department of internal medicine-oncology/hematology, will co-chair the conference.

 

Hinduja — the latest of the more than 100 strategic partners of UNMC’s International Healthcare Services — is an ultra-modern, tertiary care hospital representing the highest international standards in the delivery of health care and the most advanced knowledge and skills for health care professionals in India.

 

“As we advance toward meeting challenges in the international health care arena, the real need now is to create competent nursing leaders,” Mamdani said. “This conference will provide a platform for the nursing leaders to interact and gain insights about the challenges faced by their peers in India. I’m thrilled to take such a dynamic team to India to represent UNMC and The Nebraska Medical Center.”

 

The conference is expected to attract hundreds of nursing leaders from all parts of India and will be inaugurated by the governor of the State of Maharastra, India.

 

“I will be giving six presentations,” Schmit-Pokorny said. “We’ll be discussing stress management, critical thinking skills, work-flow processes and other aspects of nursing leadership. This is a wonderful opportunity for us to meet nurses from multiple hospital systems in India, compare nursing roles and begin a relationship that will continue far into the future.”

 

The UNMC team also will visit five other major health care facilities in Mumbai, New Delhi and Lucknow, to establish the possibilities for launching a joint venture cancer care and stem cell transplant program in India. The team also will tour the Taj Mahal and Jaipur to experience some of India’s world famous historic sites.

Unique islet transplant offers Colorado toddler hope

by Cherie Lytle, The Nebraska Medical Center

 

The two key UNMC physicians in the procedure — Drs. Jean Botha and Brian Stevens — flank Shirley and Leonard Goldstein, an Omaha couple who has contributed money in support of UNMC’s diabetes research programs.

 

Three-year-old Berlyn Alfredsen is much like any other little girl. She enjoys wearing her hair in a ponytail. Her eyes light up when she watches her favorite Elmo videos. And, brightly colored pictures decorate her room. Unlike other children, though, little Berlyn has spent much of her young life in and out of hospitals. She recently became the youngest patient known to undergo an autologous islet transplant.

 

The innovative procedure occurred April 6, at The Nebraska Medical Center, performed by a talented team of transplant surgeons and scientists under the leadership of R. Brian Stevens, M.D., Ph.D., and Jean Botha, M.D.

 

“This was quite an extraordinary process which required a truly multi-disciplinary approach,” said Dr. Stevens, director of the islet cell transplant program at UNMC and The Nebraska Medical Center. “This isn’t a procedure that would normally be performed on such a young child but Berlyn’s struggle with pancreatitis was rapidly becoming more and more critical.”

 

In severe cases of pancreatitis when the condition becomes chronic, the only real solution is to remove the entire pancreas. Dr. Botha, director of hepatobiliary surgery at The Nebraska Medical Center and assistant professor of surgery at UNMC, recommended the surgery to Berlyn’s family. “Her flare-ups were lasting days, even weeks, causing terrible pain,” Dr. Botha said. “The disease was resulting in almost weekly admissions to the hospital. This would have resulted in progressive fibrosis and scarring of her pancreas. Eventually it would no longer function or produce the insulin needed to regulate sugar levels in her body.”

 

As they considered the most effective course of treatment, Drs. Botha and Stevens also determined Berlyn would be a good candidate for the islet transplant.

 

“Without the transplant, we were certain this little girl would become a ‘brittle diabetic’ meaning she would have the most severe form of diabetes – one that is exceedingly difficult if not impossible to manage. It was a very frightening prospect considering she’s just 3-years-old,” Dr. Stevens said. “In removing the pancreas and infusing islets into the liver, we hoped at the very least to keep her blood sugar levels better controlled.”

Rare heart surgery performed at The Nebraska Medical Center

A world-class procedure and a first for North America. A life threatening aneurysm is successfully repaired at The Nebraska Medical Center using a complex technique dubbed the “frozen elephant trunk.” Published medical reports indicate this is the first time this groundbreaking procedure has been completed in the United States or Canada.

 

Ali Khoynezhad, M.D., Ph.D. performed the rare surgery. As a cardiothoracic and endovascular surgeon at The Nebraska Medical Center and assistant professor of cardiovascular and thoracic surgery at UNMC, he’s seen a variety of life threatening conditions that require urgent action. The situation he faced on Aug. 15 was different than most.

 

“Our patient was critically ill. Nearly every inch of his aorta had dissected or split,” Dr. Khoynezhad said. “Without surgery, he would have almost certainly died.”

 

Hours earlier, Michael McAlexander was at his Omaha home putting together a book shelf. The 54-year-old had run into health trouble before. The previous year he had suffered a partial dissection of his descending aorta. Brought on by extremely high blood pressure, McAlexander was put on medication to control his hypertension and was being monitored. Aches and pains were nothing new, until the inside lining along the rest of his aorta — close to his heart — ripped apart.

 

“I felt massive pain like nothing I had ever felt before. I didn’t know what it was, but I figured it would go away,” he said. “Three hours later my wife took me to the emergency room at the VA hospital. Within two hours I was transferred to The Nebraska Medical Center and prepped for surgery.”

 

Dr. Khoynezhad went into the operating room prepared to take action. He embarked on a one-of-a-kind surgery, the “frozen elephant trunk,” knowing that it provided the best option to save his patient’s life. He first replaced the ascending aorta, the aortic arch and two branch arteries to the brain, the innominate and left carotid. Badly diseased human tissue was completely replaced with a synthetic manmade material — a Dacron® vascular graft — that from this point forward would function as the aorta.

 

While most of the graft was stitched into place, an end portion was left extending inside the true lumen, or pathway, of the aorta. This seemingly minor detail is actually a critical part of the procedure.

 

“This piece of fabric is the ‘elephant trunk.’ It guides the surgical team to the true lumen, the correct channel of the aorta where blood should be flowing,” Dr. Khoynezhad said. “Remember, the dissection had split the aorta into two. If the surgeon was to misidentify the lumen and proceed with the rest of the operation in the false lumen where the vessel wall is particularly weak, it could be catastrophic.”

 

With the elephant trunk as his guide, Dr. Khoynezhad next repaired the damaged portion of the descending aorta. Over a guidewire, he inserted a permanent stent graft, the GORE TAG® thoracic endoprosthesis, through the newly rebuilt ascending aorta. He directed it into place in the descending aorta lying along the spinal column in the chest. Now that the stent was confining blood flow to the newly rebuilt vessel, blood could no longer reach the aneurysm allowing the bulge to shrink over time.

 
Adding to the complexity of this procedure — Dr. Khoynezhad and his surgical team had to initiate hypothermic circulatory arrest, cooling the patient dramatically to reduce brain and body oxygen requirements and stop blood flow in the body completely.

 

This process involves a heart-lung machine and cardiopulmonary bypass to first chill the blood and later, after completing the initial portion of surgery, to restart blood flow and rewarming. Once the patient’s body temperature reaches 18 degrees Celsius (64 degrees Fahrenheit), the bypass machine is stopped and the surgeon has a short window, 30 to 45 minutes, to complete the surgery that involves the arteries supplying blood to the brain.

 

At the same time, with the use of retrograde cerebral perfusion, a low level of cooled, oxygenated blood continues to flow to the tissue of the brain. Without this crucial component, it is not possible to replace the aortic arch. The patient would not have adequate blood flow to the brain resulting in the possibility of severe brain injury.

 

“This operation required an incredible amount of teamwork and precision by a very talented surgical team,” Dr. Khoynezhad said. “Every person in the operating room was focused from start to finish. The surgeons, the nurses, the anesthesiologist, the perfusionist — we all had a critically important job to do. Nine hours later, we wrapped up knowing that we had done all we could do to give our patient a second chance.”

 

Less than 12 hours after surgery, Michael McAlexander was breathing on his own and without the use of a ventilator. Several days later he was discharged. Numerous check-ups and scans in the months following show his recovery is going well.

 

“I’m thankful. My wife Cheryl, Dr. Khoynezhad and God have seen me through this,” McAlexander said. “It is taking a while for my strength and stamina to return. I still have aches and pains but I am feeling better.”

 

Variations of the frozen elephant trunk procedure for aortic dissection have been performed previously in the United States, however, instead of repairing all portions of the aorta in one session the earlier operations were split into at least two separate procedures happening days or even weeks apart.

 

Kim Duncan, M.D., chief of cardiothoracic surgery and professor of cardiothoracic surgery at UNMC, stresses the combined nature of the operation speaks highly of the skill and collaboration of Dr. Khoynezhad and his team in this innovative approach to patient care.

 

“The hybrid procedure using open surgical technique along with the intraoperative use of endovascular stenting techniques made this procedure shorter, more efficient and ultimately safer for the patient,” Dr. Duncan said. “People in this region need to know they don’t have to travel far to find the best, most advanced vascular and cardiac care. We’re providing it right here in Omaha.”

 

In April of 2006, Dr. Khoynezhad performed a separate groundbreaking surgery — Omaha’s first minimally invasive repair of a life threatening thoracic aortic aneurysm. This procedure also relied on an endovascular approach. The same type of thoracic aortic stent used in the frozen elephant trunk procedure was delivered through the femoral artery in the groin and expanded inside the abnormally distended aorta in the chest.

 

To date, the only published reports on complete frozen elephant trunk surgeries for aortic dissection come from surgeons in Germany and Japan.

Bone Marrow Transplantation; A Success Story
 

Editorial in Middle East Health Magazine, Dec. 2006 by James O. Armitage, MD/University of Nebraska Medical Center, Omaha, NE, USA

 

It is very popular today to speak of stem cell research and the use of stem cells to treat disease.  However, many involved in the debate regarding research and clinical applications of stem cells might not appreciate that hematopoietic stem cells have been used therapeutically for half a decade.  Attempts to use hematopoietic stem cells to replace marrow aplastic anemia or to support intensive therapy of cancer began even more than 50 years ago.  However, it was not until more was understood about bone marrow functions and the nature of the hematopoietic stem cell before the procedure that we know today as hematopoietic stem cell transplantation became practical.  In the 1960’s successful allogeneic (i.e. from one individual to another) hematopoietic stem cell transplantation was reported for the treatment of leukemia and for the treatment of inherited immune defects.  Working at the University of Washington in Seattle Dr. Don Thomas (i.e. who won the Nobel Prize) and his colleagues worked out the techniques of hematopoietic stem cell transplantation to treat leukemia and aplastic anemia.  By the mid 1970s they reported 100 patients with acute leukemia treated with this approach with some patients surviving free of disease and apparently cured.

 

The presumed benefit of allogeneic hematopoietic stem cell transplantation was originally thought to be a consequence of the very intensive therapy administered before the infusion of hematopoietic stem cells.  It was known that unless a severely immunosuppressive treatment was applied, the patients own immune system would destroy the new hematopoietic stem cells.  Thus, high dose therapy was administered before the transplant in an attempt to allow engraftment and to eradicate the malignancy—i.e. usually leukemia.  Proof that immunosuppression was also required came from attempts to do hematopoietic stem cell transplantation in aplastic anemia.  It was originally felt that simply infusing hematopoietic stem cells should cure this disease since the marrow was “empty”.  However, it became apparent that in the absence of destruction of the patient’s residual immune cells, the new hematopoietic stem cells would be destroyed.  Thus, in patients with cancer, the very intensive therapy administered before infusion of the new hematopoietic stem cells was felt to be both curative of the cancer and engraftment.

 

In the late 1970’s and early 1980’s, it became apparent that the new hematopoietic stem cells and the new immune system that they produced in the patient might also have an anticancer effect.  The main complication of allogeneic hematopoietic stem cell transplantation is the development of a condition known as graft versus host disease.  In this illness, the new immune system produced by the infused, allogeneic hematopoietic stem cells can recognize the patient as “foreign” and carry out an immune attack on the patient’s organs.  Injury in this condition is especially frequently seen in the skin, liver, and gastrointestinal tract, and can some times be fatal.  In the late 1970s and early 1980s remission of relapsed leukemia was noted in patients who developed severe graft versus host disease.  It was speculated that there might be a graft versus leukemia effect and that it could be therapeutically important.  Careful studies of large numbers of patients demonstrated that patients who developed graft versus host, were less likely to have recurrent leukemia.  In fact, it appeared that much of the curative effect of allogeneic hematopoietic stem cell transplantation might be from the anticancer effect of the new immune system.

 

This observation led to attempts at reducing the intensity of the pretransplant therapy to reduce some of the risks of the procedure.  It is possible to use predominantly drugs that impair lymphocyte function with relatively minor toxic effects in the patient and avoid very high doses of other chemotherapeutic agents or total body radiotherapy.  It became apparent that sufficient impairment of the patient’s lymphocytes could allow the new hematopoietic stem cell graft to grow and eventually destroy the residual host lymphocytes giving a complete graft.  In some cancers that seem to be particularly sensitive to immunological attack, e.g. chronic myeloid leukemia and chronic lymphoid leukemia, the graft versus leukemia effect seems to be potentially curative and the reduced intensity treatment before the transplant appears to reduce transplant related mortality.  In those patients in whom the cancer does recur, reinfusing more of the donor’s lymphocytes often will reestablish remission.  This approach is sometimes termed reduced intensity allogeneic hematopoietic stem cell transplantation, or mini transplant is now undergoing intensive study in transplant centers throughout the world.

 

The idea that very high doses of anticancer therapy might be curative for some patients with cancer, and that the use of reinfusion of the patients own hematopoietic stem cells could avoid the dangers of graft versus host disease, led to clinical trials in what is called autologous hematopoietic stem cell transplantation.  In this treatment, hematopoietic stem cells have to be removed from the patient and stored until after the intensive cancer therapy is administered.  Since the patient’s own hematopoietic stem cells would be used to reestablish bone marrow function after the treatment, there would be no risk of graft versus host disease.  However, early problems with this treatment approach included occasional difficulties in collecting hematopoietic stem cells that were free of contamination by cancer cells and finding a way to store the hematopoietic stem cells for extended periods of time and keep them alive.  In allogeneic transplantation, the hematopoietic stem cells are taken from one individual and reinfused quickly into another.  However, since it takes time to administer the very intensive therapy, hematopoietic stem cells in autologous transplantation have to be cryopreserved for days to weeks before they are used.  Initial attempts at autologous hematopoietic stem cell transplantation involved repetitive bone marrow aspirations from the pelvis and sternum to collect sufficient cells.  It was not unusual for 200 aspirates to be required.  However, in the mid to late 1980s it became apparent that circulating hematopoietic stem cells could be collected using the process called aphersis where the blood is taken from the body, separated by centrifugation, and the desired cells collected with the rest of the blood reinfused into the patient.

 

Autologous hematopoietic stem cell transplantation tested the hypothesis that very intensive anticancer therapy could cure some patients when standard therapy failed.  Early studies in lymphoma showed that this can, in fact, be the case.  In patients whose recurrent or resistant lymphoma still can partially respond to standard doses or chemotherapy and achieve a minimal disease state, hematopoietic stem cell transplantation can often be curative.  As is the situation with allogeneic hematopoietic stem cell transplantation, treatment doesn’t benefit patients with all cancers, but is especially effective in patients with lymphoma, certain leukemias, multiple myeloma, and occasional other cancers.

 

Today both allogeneic and autologous hematopoietic stem cell transplantation are widely utilized to treat patients with cancer.  Many patients who would otherwise have died of their malignancy are now cured because of these procedures.  Allogeneic hematopoietic stem cell transplantation is also utilized for patients with aplastic anemia, inherited immune deficiency states, and certain other inherited disorders of blood production.  Both allogeneic and autologous hematopoietic stem cell transplantation are being studied in the treatment of patients with other life threatening immune diseases.  It is likely that both treatments will continue to be an important part of our therapeutic armentarium for years to come.
