Woman Not Diabetic After Cell Transplant
A diabetic woman no longer needs to take dailymedicine after she received a stem cell transplant.
The daily insulin injection had helped control theamount of sugar -- or glucose -- in her blood.Wendy Peacock was first diagnosed with type 1diabetes at age 17, according to the Miami Herald newpaper.
Ms. Peacock, who is now 43, received the stem cells in mid-August in a "minimally invasiveprocedure" at the University of Miami-Miller School of Medicine in Florida. Doctors called theoperation simple and said Ms. Peacock recovered quickly.
After the operation, her body started producing insulin naturally.
Ms. Peacock "is now completely off insulin," one of her doctors said.
"These are the best ... results we've seen," said Dr. Camillo Ricordi, director of the CellTransplant Center at the Diabetes Research Center in Florida.
"If these results can be confirmed, this can be the beginning of a new era in ...transplantation," said Dr. Ricordi. If other doctors study the results and confirm theoutcome, the procedure could become available to other diabetics.
Ms. Peacock says her life has changed dramatically as a result of the operation. Before theoperation, Ms. Peacock was unable to sense when her blood glucose dropped dangerously. Lowglucose can make a person confused or unconscious. It may even lead to death.
Now she does not need to monitor her blood glucose. "As any type 1 knows, you live on a verystructured schedule," Ms. Peacock explained. "I do a mental checklist every day in my head ...glucose tabs, food, glucometer, etc., and then I stop and say, 'WOW! I don't have to plan thatanymore.' "
Asians will find the medical news encouraging. Studies have shown that Asians are at higher riskof developing type 2 diabetes, when compared with people of European ancestry. That'saccording to the Asian Diabetes Prevention Initiative at Harvard University in Massachusetts.
Asian populations have fewer overweight and obese people than people in the West. But theyhave a higher percentage of people with diabetes. Currently, 60 percent of the world's diabeticpopulation is Asian, according to the Initiative's website.
