Treat Diabetes Early and Aggressively

Doctors need to check patients for diabetes if they even suspect a patient may have the condition, and start using drugs to treat it right away, according to new guidelines released on Wednesday.

An estimated 90 percent of all patients diagnosed with diabetes are not controlling it enough to prevent heart disease and other complications, the experts at the American College of Endocrinology and the American Association of Clinical Endocrinologists said.

At-risk patients, such as the overweight, should start getting screened at 30. If they show poor control of blood sugar, they should go on drugs right away, the two groups said.

"Numerous studies have shown that significant cardiovascular disease develops years before the onset of diabetes," the groups said in a statement.

A measure of glucose control called A1C should bring back a result of 6.5 percent or lower, the groups said. Fasting glucose should be 110 or below and a two-hour glucose challenge test should come back 140 or below.

"Patients with diabetes are often in denial," said Dr. Jaime Davidson, an endocrinologist at the University of Texas Southwestern Medical School in Dallas and chairman of the guidelines conference.

If a family doctor or primary care doctor suspects a patient may have diabetes, even a young patient, he or she should test immediately, Davidson said.

And a fasting glucose test is no good, he said. The patient should undergo a two-hour glucose challenge to see how well his or her body controls blood sugar.

Insurance companies may balk at paying for the tests, but they shouldn't, Davidson said.

"It is cheaper to pay for that today than to pay for the first heart attack," Davidson said in an interview.

The groups acknowledged that diet and exercise can stop a person from becoming diabetic, but said most patients fail.

"Lifestyle is essential. But in the real world it doesn't really allow us to get a patient to target," said Dr. Harold Lebovitz of the State University of New York, who chaired the writing committee.

"Doctors have big hearts and patients come to them to say 'Give me another chance. Give me a diet. Give me another three months,"' Davidson said.

But he said damage can occur during those three months. "We prefer to get them on target from day one and keep them there," he said.

Diabetics also need to see their doctors often. "If they are diabetic, one time a year is not enough. Because in that time, something is going to happen."

An estimated 20 million Americans have type-2 diabetes and one-third do not know it, the groups said. Another 41 million have what is known as "pre-diabetes," which will develop into diabetes if not controlled.

Diabetes costs the economy $132 billion a year, according to the American Diabetes Association.

"Eighty percent of the money spent is not in treating diabetes. Eighty percent of that money is spent in treating complications," Davidson said.

Drug treatments include metformin, the glitazone or thiazolidinedione class of drugs which includes GlaxoSmithKline's Avandia, and orlistat, sold under the brand name Xenical by Roche. Orlistat is a weight loss drug that also appears to prevent progression to diabetes.

Study: Lymphoma Treatment Shows Promise

A one-time treatment that uses a homing-device drug to zap cancer cells with radiation made a deadly lymphoma disappear in three out of four patients, many for nearly eight years, researchers report.

While the results were called promising, it's not known yet whether the novel approach will be superior to the standard early treatments normally used for a slow-growing but incurable type of non-Hodgkin's lymphoma.

"The striking thing about it is how such a short treatment can produce such long-lasting remissions," said Dr. Mark S. Kaminski, who developed the new treatment, Bexxar, with a University of Michigan colleague.

The researchers said more studies will be needed to determine whether doctors should use Bexxar as a first treatment to fight the immune-system cancer. Bexxar is only approved for use when other therapies, including chemotherapy and radiation, fail.

Bexxar treatment starts with a test dose followed by a full dose a week later instead of over months, as with chemotherapy. One advantage is fewer side effects, such as hair loss, the researchers said.

The findings reported in Thursday's New England Journal of Medicine were partly funded by drug maker Corixa, which recently sold the rights to Bexxar to GlaxoSmithKline. Some of the scientists have received fees from the drug makers; one was a Corixa employee. The university holds patents for Bexxar, and Kaminski and his co-inventor share in royalties.

Dr. Joseph M. Connors, of the British Columbia Cancer Agency in Vancouver, said the results were impressive even though they involved carefully chosen patients and no comparison group.

"This is quite promising and firmly indicates that we need to know what would happen in comparisons to standard treatment" said Connors, who wrote an accompanying editorial.

The Michigan researchers tested Bexxar in 76 patients with advanced follicular lymphoma who had received no other treatment. Follicular lymphoma strikes about 15,000 adults in North America each year. Patients typically survive seven to 10 years.

The approach used in Bexxar, called radioimmunotherapy, delivers lethal radiation directly to cancer cells. The method is being tested in other types of cancers, and Bexxar and another treatment called Zevalin are approved for advanced non-Hodgkin's lymphoma. In Bexxar, radioactive iodine-131 is attached to antibodies that target and kill lymphoma cells.

In the study, 72 patients or 95 percent had some shrinkage of their tumors after getting Bexxar. The cancer disappeared in 57 participants (75 percent), and three-quarters of them were still disease-free after five years. Many remained cancer-free until the end of the study, a maximum of about eight years. The researchers are continuing to follow the participants.

The most common side effect was a brief drop in white blood cells. Nine patients died, six from lymphoma.
