"The protocol greatly benefits some patients with severe type 1               diabetes, but two or more infusions of islets are usually needed,               and the islets tend to lose their insulin-producing function over               time.  Participating in an islet transplant study is appropriate               for people with severe hypoglycemia (dangerously low levels               of blood sugar) and for those with type 1 diabetes who have had               a kidney transplant to treat kidney failure, a complication of               diabetes."'
