Summary
Post-transplant diabetes mellitus (PTDM) is distinct from pancreas graft failure. This framework helps diagnose and manage PTDM in pancreas transplant recipients for better outcomes.
Area of Science:
- Nephrology
- Endocrinology
- Transplantation
Background:
- Pancreas transplantation (PTX) is effective for diabetes, but post-transplant diabetes mellitus (PTDM) can occur.
- PTDM is distinct from pancreas graft failure (PGF) and other hyperglycemia causes post-PTX.
Purpose of the Study:
- Propose a diagnostic and management framework for PTDM after PTX.
- Distinguish PTDM from PGF and transient hyperglycemia.
Main Methods:
- Defined PTDM as persistent hyperglycemia with a functioning graft, excluding rejection, infection, or technical issues.
- Diagnosis after immunosuppression stabilization.
- Identified risk factors: donor age, recipient obesity, insulin use, weight gain, immunosuppressants (tacrolimus, glucocorticoids).
Main Results:
- PTDM mimics PGF and is linked to adverse outcomes.
- Pharmacologic management options include metformin, SGLT2 inhibitors, GLP-1 RAs, DPP-4 inhibitors, or insulin.
- Multidisciplinary care and weight management are crucial.
Conclusions:
- A clear diagnostic and management strategy is needed for PTDM post-PTX.
- Early identification and intervention can mitigate PTDM's adverse effects.
- Integrated care optimizes outcomes for pancreas transplant recipients.

01:29Hyperglycemia
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
01:15Hypoglycemia and Glucagon
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
01:36Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

01:16Hormones Regulating Blood Glucose
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
