The results of this study allowed us to determine a high-risk group for SMI in the diabetic population. SMI with significant lesions occurs in 20.9% of type 2 diabetic male patients who are totally asymptomatic for CAD. Based on these findings, we recommend routine screening for male patients in whom the duration of type 2 diabetes is >10 years or even less when more than one cardiovascular risk factor is present.

When used in external pumps, LP provides better glycemic control and stability than regular insulin and does not increase the frequency of hypoglycemic episodes.

Intraperitoneal insulin infusion using an implantable programmable pump is a feasible and relatively safe technique that may improve metabolic control and glycemic stability. Long-term studies, however, are needed to demonstrate whether or not the improvement in glycemic control could be sustained for several years.

In vivo and in vitro experiments have shown that nicotinamide enhances the regeneration of rat B cells. Nicotinamide has been administered to human subjects at a dose of 3 g/day for more than one year without any serious side effects. A trial was conducted to study if nicotinamide could protect B cells in Type I (insulin-dependent) diabetic patients with established diabetes, but still with residual insulin secretion, the latter being evaluated throughout the study period. A randomized double-blind study was carried out on 26 Type I diabetic patients aged 15 to 40 years who had been treated with insulin for 1 to 5 years but who had a residual insulin secretion characterized by a glucagon stimulated C-peptide level higher than 0.1 nmol/l. They were given either 3 g/day of nicotinamide or a placebo for nine months. At baseline the treated and control groups did not differ according to age, diabetes duration, insulin dose, HbA1c or C-peptide levels. Three patients dropped out of the study. At 9 months there were no significant changes in the insulin doses required. However, HbA1c rose in the control group (8.1 +/- 0.4 vs 9.8 +/- 0.5%, p less than 0.05) but not in the nicotinamide treated group (7.5 +/- 0.5 vs 6.9 +/- 0.4%).(ABSTRACT TRUNCATED AT 250 WORDS)
