A team at the University of Chicago Medicine Transplant Institute has updated the results of the ongoing clinical trial of patients with type 1 diabetes.
Unlike type 2 diabetes, which typically comes on later in life and is caused by lifestyle factors such as obesity, type 1 diabetes, which affects as many as 4 million Americans, is an unpreventable autoimmune disorder in which the immune system destroys insulin-producing cells in the pancreas.
Without insulin, type 1 diabetics' bodies have no way to regulate blood sugar, which can build up in the bloodstream and skyrocket. Instead, their bodies break down fat for fuel, creating acidic byproducts called ketones and eventually cause diabetic ketoacidosis (DKA), leading to brain swelling, kidney failure, cardiac arrest and potential death.
In the trial, 10 type 1 diabetics underwent transplantation of islet cells, tiny clusters of specialized cells scattered throughout the pancreas that produce hormones to regulate blood sugar.
After just four weeks, all 10 achieved insulin independence, meaning their bodies were able to produce insulin on their own without costly supplemental injections.
Their A1C, which measures the amount of glucose in the blood, also fell from eight percent on average, which indicates diabetes, to 5.3 percent, which is considered non-diabetic.
The new results, unveiled earlier this month, are updated from initial findings published last year, which showed an initial favorable response and gradually decreasing A1C levels.
