Our Summary
This research paper reviews recent studies on the use of pancreas and islet transplantation, as well as conventional insulin therapy, for treating diabetes and its related complications. It highlights the current state of these treatments, their challenges, and future prospects, including potential new cell therapies. The research shows that while modern insulin delivery and monitoring technologies are becoming more effective, so too are pancreas and islet transplants, which are becoming safer and more successful. However, these transplant therapies are limited by the need for immunosuppression and a shortage of donor organs. Because of the proven success of these therapies for improving lifespan and quality of life, scientists are actively looking into alternative cell sources and ways to prevent transplanted cells from being damaged by the immune system. The main goals of diabetes treatment are to maintain normal blood sugar levels, avoid low blood sugar, and prevent or halt damage to organs. Bearing these in mind, all treatment options should be considered.

Doctor’s Tip
A helpful tip a doctor might tell a patient about pancreas transplant is to carefully weigh the risks and benefits of the procedure. While pancreas transplants can be successful in improving blood sugar control and quality of life for some patients with diabetes, there are also risks associated with the surgery and the need for lifelong immunosuppressive medications. It’s important for patients to have a thorough discussion with their healthcare team about their individual situation, including their overall health, goals for treatment, and potential complications. Patients should also be aware of alternative treatment options, such as insulin therapy or islet transplantation, and work with their doctor to determine the best course of action for their specific needs and preferences.
Suitable For
Patients who are typically recommended for pancreas transplant are those with type 1 diabetes who have difficulty controlling their blood sugar levels despite optimal insulin therapy and who are experiencing severe complications such as kidney failure, nerve damage, or vision problems. Additionally, patients who have frequent episodes of severe hypoglycemia (low blood sugar) that are not responsive to other treatments may also be considered for pancreas transplant. It is important to note that pancreas transplant is a complex procedure with risks and potential complications, so it is typically reserved for patients who have exhausted other treatment options and who are in good overall health.
Timeline
Before pancreas transplant:
Diagnosis of diabetes: The patient is diagnosed with type 1 diabetes or severe type 2 diabetes that is not well controlled with insulin therapy.
Insulin therapy: The patient undergoes insulin therapy to manage their blood sugar levels, which may involve multiple daily injections or the use of an insulin pump.
Complications: Over time, the patient may develop complications of diabetes, such as kidney disease, nerve damage, or eye problems, despite insulin therapy.
Evaluation: The patient is evaluated by a transplant team to determine if they are a candidate for a pancreas transplant. This evaluation includes tests to assess overall health and to determine if the patient is a suitable candidate for surgery.
Waiting list: If the patient is deemed eligible for a pancreas transplant, they are placed on a waiting list for a donor pancreas. The wait time can vary depending on organ availability and the patient’s medical condition.
After pancreas transplant:
Surgery: The patient undergoes a surgical procedure to remove their diseased pancreas and replace it with a donor pancreas. The surgery can take several hours and requires a hospital stay of about 1-2 weeks.
Recovery: After the transplant, the patient will need to recover from surgery and adjust to life with a new pancreas. They will be closely monitored for signs of rejection or complications.
Immunosuppression: The patient will need to take immunosuppressive medications for the rest of their life to prevent rejection of the donor pancreas. These medications have potential side effects and require close monitoring.
Monitoring: The patient will need regular follow-up appointments with their transplant team to monitor the function of the new pancreas and to adjust medications as needed.
Improved quality of life: With a successful pancreas transplant, the patient may experience improved blood sugar control, reduced risk of complications, and a better quality of life overall. They may be able to reduce or eliminate their need for insulin therapy.
