New tools, such as genome-wide association studies, have provided evidence for new susceptibility loci and candidate genes in the disease process including common susceptibility genes involved in the immunological synapse and T cell activation. Close linkages have been found in a number of diseases, including ankylosing spondylitis, multiple sclerosis, Crohn’s disease and insulin-dependent diabetes mellitus (Type 1 diabetes mellitus). The evidence for some associations with Type 1 diabetes was previously found in the region containing 5q15/ERAP1 (endoplasmic reticulum aminopeptidase 1) (rs30187, ARTS1). Our aim was to conduct the first casecontrol study to test the association between the rs30187 polymorphism of ERAP1 and the development of Type 1 diabetes mellitus in patients selected from continental Italy. All control subjects were matched for the sex, age, ethnic origin and geographical area. Genotyping of the rs30187 polymorphism of ERAP1 was carried out by the allelic discrimination assay on DNA extracted from whole blood. We did not observe a statistically significant prevalence of the rs30187 polymorphism of ERAP1 in our cohort of patients than in controls suggesting a minor contribution of this gene to the pathogenesis of Type 1 diabetes mellitus in Italian patients.展开更多

A successful whole pancreas or islet transplant offers the advantages of attaining normal or near normal blood glucose control and normal hemoglobin Alc levels without the risks of severe hypoglycemia associate with intensive insulin therapy. Both forms of transplants are also effective at eliminating the occurrence of significant hypoglycemic events （even with only partial islet function evident）. Whereas whole pancreas transplantation has also been shown to be very effective at maintaining a euglycemic state over a sustained period of time, thus providing an opportunity for a recipient to benefit from improvement of their blood glucose control, it is associated with a significant risk of surgical and post-operative complications. Islet transplantation is attractive as a less invasive alternative to whole pancreas transplant and offers the future promise of immunosuppression-free transplantation through pretransplant culture. Islet transplantation however, may not always achieve the sustained level of tight glucose control necessary for reducing the risk of secondary diabetic complications and exposes the patient to the adverse effects of immunosuppression. Although recent advances have led to an increased rate of obtaining insulin-independence following islet transplantation, further developments are needed to improve the longterm viability and function of the graft to maintain improved glucose control over time.展开更多

Diabetes Mellitus resulting in fluid shifts, electrolytes imbalance and acid-base disorders, can lead to multi-organ Failure. The Pancreas and skeletal muscles are not commonly affected in DKA. We present a case of 41-year-old female who was initially admitted in intensive care unit for treatment of Diabetic ketoacidosis, and was treated appropriately later she complained of abdominal pain and generalized myalgia. Hospital course was complicated with Acute pancreatitis and Rhabdomyolysis. Serum electrolytes were significant for hypo-phosphatemia. Workup for myositis and acute pancreatitis were negative. The exact etiology is unknown, but it is proposed in many literature articles that serum hyper-osmolarity and/or electrolyte abnormalities can be the culprits in triggering the complications.展开更多
