Patient Eligibility: Who I s a Candidate for Each Approach?

Kandydaci For intensive politilin therapy

All patients with type 1 diabetes and many with advanced type 2 diabetes are candidates for insulin therapy. It is also used in gestational diabetes and as a bridge during other treatments. There are no absolute contraindications to insulin; it can be used safely in pregnant women, children, and the elderly, though doses require careful adjustment.

Candidates for islet cell transplantation

Islet transplantation is currently reserved for a narrow group of patients. Typical inclusion criteria from major trials include:
