Isolating a diabetes cureClinical Center's Cell Processing Section leads in islet cell isolation The Clinical Center's Department of Transfusion Medicine is once again at the forefront of exciting new clinical research as its Cell Processing Section (CPS) prepares islet cells for transplantation in an effort to cure diabetes. Canadian researchers made headlines last month when they reported successfully transplanting insulin-producing islet cells into eight patients with diabetes, freeing them from daily insulin shots. The CPS is working hand in hand with NIDDK researcher Dr. David Harlan to replicate and improve upon the Canadians' work here at the Clinical Center. However, according to Dr. Harlan, "Islet isolation is not simple. There are a lot of variables to consider." It all starts with a donor pancreas. Islet cells are clustered in ducts deep within the organ and make up only about 2 to 3 percent of its cellular mass. Extracting the islets requires a 6-hour procedure and three CPS technologists working simultaneously in a sterile environment. In brief, fat is trimmed off the pancreas, and an enzyme called collagenase is pumped into the ducts. The enzyme digests away the connective tissue that comprises most of the pancreas. To aid the breakdown process, the tissue is also placed in a stainless steel chamber full of marbles and agitated back and forth. As the islet cells are released, they are further separated and washed. The result is a volume of pure islet cells ready for transplantation into the patient's liver via the portal vein. This will be done in the Diagnostic Radiology Department's Special Procedures Lab. Once imbedded in the liver, the islet cells appear to produce insulin in response to blood sugar levels, according to the Canadian team's report. Already skilled in cell-processing techniques, CPS lead technologists Janet Lee and Ken Hines visited experts at the University of Miami in early 1999 to learn the basics of islet isolation. They carried their new knowledge back to the Clinical Center, and set to work modifying their lab to do islet isolations for Dr. Harlan's original protocol, which planned to test an antirejection drug called anti-CD154. That study was shelved when the drug was found to cause blood clots. Dr. Harlan retooled his approach to replicate the Canadian team's work, and Lee and Hines recently visited the Canadians to see exactly how they do their isolations. The CPS team has processed more than 20 pancreata so far, and they are ready to move forward with a clinical application. The cell processing facility opened in 1997 with the goals of developing and improving procedures for collecting, modifying, growing, and preserving human cellular components. The facility was designed to meet the Food and Drug Administration's regulatory requirements for a biologics production facility. A biologic is a treatment derived from a living organism, for example, a vaccine. Islet cells fall into this category. "The isolation process is very labor intensive, and one of our goals is to streamline and automate parts of it," said CPS chief Dr. Elizabeth Read. She also pointed out that each pancreas yields different amounts of islets. Additional research goals include standardizing the "dose" of islets and developing ways to predict the amount of insulin they might produce once in the body. Other CPS staff involved in this work include section supervisor Charley Carter, Sue Ellen Frodigh, Larry Moses, Chauha Pham, Angela Pickett, and Hoi May Wong. Three technologists are on call 24 hours a day, because a pancreas can arrive at any time. "Their expertise, attention, and effort put together the islet isolation unit. They bring a squared-away, regulatory mindset to the process that a clinician might not have," said Dr. Harlan. "Only eight patients in the world have had this therapy work, and none of them have been in the United States. It is still very experimental. NIH will be one of the first institutions to try this therapy in humans," said Dr. Harlan. His new protocol is in review. He hopes to study up to 20 patients. And CPS will be with him every step of the way. -by Sue Kendall |
"Clinical
Research Training" course to begin soon
|
A new course for clinical principal investigators, "Clinical Research Training," will be offered Sept. 12 from 12 noon to 4 p.m. in Lipsett Amphitheater. This course was designed to address one of the essential standards recently approved by the NIH for performing clinical research. All clinical principal investigators are required to take the course and successfully complete a final exam. Former participants of the "Introduction to the Principles and Practice of Clinical Research" and "Ethical and Regulatory Aspects of Human Subjects Research" who have passed both courses, as exhibited by successful completion of the final exam given in each program, will not be required to take the course. Course topics include:
Enrollment in the initial course offering will be limited to those individuals for whom it is required. Registration begins on Aug. 1 and ends on Aug. 30. The course will be repeated Dec. 12. |
"Principles
of Pharmacology" course to begin soon
|
The "Principles of Clinical Pharmacology Course," sponsored by the Clinical Center, will begin Sept. 7. The course will be held Thursdays from 6:30 p.m. to 8 p.m. in Lipsett Amphitheater, and runs through April 26, 2001. Topics include: pharmacokinetics; drug metabolism and transport; assessment of drug effects; drug therapy in special populations; and drug discovery and development.\ An outstanding faculty has been assembled to present the lectures, including Dr. Carl Peck of Georgetown University's Center for Drug Development Science, Dr. Jerry Collins of the Food and Drug Administration, and the Clinical Center's Dr. Arthur J. Atkinson, Jr., course director. Before coming to NIH, Dr. Atkinson was at Northwestern University, where he directed the Clinical Pharmacology Center, and at the Upjohn Company, where he was in charge of clinical drug development programs. This is the third year that the course is being offered. Last year 305 students registered, and there was considerable sustained enthusiasm for the course. Registration is free and open to all interested persons. Syllabus materials will be provided for each lecture. Certificates will be awarded at the end of the course to students who attend 75 percent of the lectures. |
Reduce! Reuse! Recycle!
|
Were you among the folks who thought "Clean Your Files Week" (April 17-21) was a good idea but did not quite get around to it then? Perhaps you were confused because your office did not have bins for recycling either white office or mixed paper. You are not alone. Although recycling has grown at NIH since the mid-1980's, and paper recycling was high during the recent "Clean Your Files Week," there is room for improvement, said David Crook, recycling coordinator in the Environmental Protection Branch, Division of Safety, ORS. According to Crook and William (Kenny) Floyd, chief, EPB Waste Management Section, the amount of waste generated in Bldg. 10 alone is about one quarter of the campus total (3,203 of 11,500 tons last year). The CC currently recycles 28 percent of its wastes, and NIH, about 30 percent. Could we do better? The official recycling goal is 50 percent in Montgomery County, Md., where NIH is located, and the county itself recycled 36 percent last year. The Montgomery County recycling regulation says that businesses, including government facilities, must recycle office paper, corrugated cardboard, newsprint, aluminum and bi-metal food and beverage cans, glass and plastic food and beverage containers, and yard trimmings. Businesses can voluntarily recycle scrap metal, plastic film, food waste, wood waste, batteries, motor oil and antifreeze, construction and demolition debris, toner cartridges, and phone books. But how? Crook works with each NIH building or cluster to devise a recycling plan. Volunteer area coordinators help by determining which categories each office, corridor, or complex is willing to recycle and by calling Crook to arrange for containers or for troubleshooting. In a typical week in early spring 2000, the CC generated 2.8 tons of recyclables in a campuswide total of 12.1 tons. Crook emphasizes that the main goal of recycling is to reduce the amount of waste going to landfills. The fact that recycling also reduces the cost of waste disposal (about $44 per ton) is a bonus. The 1999 bonus was $125,000 for 2,842 tons that NIH recycled in a year. Aluminum is the clear winner when it comes to the value of recycling-both for cash payback and environmental value. Scrap metal dealers this spring were paying nearly $640 per ton. Every ton recycled is one less ton to be imported: the United States no longer mines any aluminum and must import all of it. The per-ton payback recently for some other wastes was $120 for office paper; $30 for cardboard; and $10 for scrap metal. The NIH waste contractor looks for the best price when hauling the recyclables to local dealers. How could the CC do more to reduce waste? Crook says, "If you could get all that mixed paper out of the trash, it would make a huge difference." Many papers listed as "don'ts" on the white office paper recycling containers are eligible for recycling in the mixed paper containers. Rental buildings in Montgomery County, such as on Executive Boulevard where many CC off-campus employees work, are required to make collection and storage of recyclables available, if requested, to tenants. But a county brochure notes, "The responsibility for participating and reporting, however, falls to the individual business (already defined as including government facilities) generating the waste materials." To learn more about NIH recycling or to request supplies, visit the recycling website http://www.nih.gov/od/ors/ds/recycle/. If you cannot find a volunteer area coordinator listed for your area, Crook points out, "A sign-up form is always available on the website!" Or you can call him at 2-6036. -by Linda Silversmith |
