BACKGROUND Diabetes is an increasingly prevalent comorbidity in patients presenting for surgery, impacting nearly 14% of adults in the United States. Although it is known that diabetic patients are at an increased risk for postoperative complications, there is a paucity of literature on the specific ramifications of diabetes on different surgical procedures. METHODS Using the American College...

Polymorphic restriction endonuclease sites within the HLA-DR alpha gene have been defined, localized, and used as genetic markers in the analysis of susceptibility to insulin-dependent diabetes mellitus (IDDM). Hybridization of Bgl II-digested human genomic DNA with a cDNA clone for the HLA-DR alpha chain (pDR alpha-1) has revealed three allelic restriction fragment lengths: 3.8 kilobase pairs ...

Hematological abnormalities associated with the diabetic state include reduced platelet function, enhanced factor activation and hyperfibrinolysis. The present investigation evaluated blood loss and the transfusion requirements in diabetic and non-diabetic patients undergoing extracorporeal circulation and cardiac surgery. A retrospective study of 151 consecutive patients undergoing primary cor...

Both in patients with IDDM (1) and in healthy control subjects (2,3), increased urinary albumin excretion rate (AER) is associated with high relative morbidity and mortality. In IDDM patients, genetic susceptibility factors are most likely contributing to an increased AER (4,5) resulting in a cumulative incidence of nephropathy (AER >300 mg/24 h) of -30% (6). So far, candidate genes, proposed a...

AIMS To assess the prevalence of dysthyroid optic neuropathy (DON) in patients with diabetes mellitus (DM) and Graves' orbitopathy (GO) and to investigate the complications of surgery for GO in these patients. METHODS The records of 482 consecutive patients with GO referred in a 5 year period were studied. Those patients who also had DM were selected for further study. The prevalence of insul...

Insulin-dependent diabetes mellitus (IDDM) is caused by destruction of the insulin-secreting p-cells of the islets of Langerhans. It is proposed that the disease is caused by nongenetic, probably environmental, factors operating in a genetically susceptible host to initiate a destructive immune process. These environmental factors may operate over a limited period in early childhood to induce t...

OBJECTIVE Protection of residual beta cell function at the time of diagnosis of insulin-dependent diabetes mellitus (IDDM) by intensive insulin therapy and the addition of nicotinamide (NA) has been established. The objective of this study was to evaluate the effect of a free oxygen radical scavenger such as vitamin E (Vit E) on residual beta cell function and parameters of metabolic control in...

BACKGROUND Genotypic abnormalities of the renin-angiotensin system have been suggested as risk factors for the development of hypertension, diabetic nephropathy and proliferative retinopathy. Most of the known actions of angiotensin-II are exerted through the angiotensin-II type 1 receptor, which is present particularly in vascular smooth muscle cells, myocardium and the kidney. A transversion ...

The cellular and molecular physiology and pathology of insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM) are mostly studied and understood through the use of animal models. Fundamental differences between the IDDM and NIDDM animal models may help to explain the etiology behind diabetic cardiomyopathy, one of the most severe complications of IDDM. Exp...

Patients with insulin-dependent diabetes (IDDM) possess antibodies to islet proteins of M(r)-64,000. Potential autoantigens of this M(r) include glutamate decarboxylase (GAD) and 65 kD heat shock protein. We have detected two distinct antibody specificities in IDDM that bind 50,000 M(r) or 37,000/40,000 M(r) proteolytic fragments of 64,000 M(r) proteins. In this study, we investigated relations...
