Obesity does not modulate insulin secretion in Indian patients with non-insulin-dependent diabetes in the young.

The insulin response to a 100-g oral glucose load was studied in 40 obese (percent desirable weight greater than or equal to 120%) and 40 nonobese (less than 120%) age- and sex-matched Indian patients with non-insulin-dependent diabetes in the young. There were no significant differences between the obese and nonobese patients with respect to their insulin and glucose responses. Thus, it appears that obesity does not exert a significant modulating effect on insulin secretion in patients with fasting hyperglycemia.

Nephropathy in Indian patients with non-insulin-dependent diabetes in the young.

In 85 patients diagnosed as having non-insulin-dependent diabetes in the young (NIDDY), 6 were found to have nephropathy. The duration of diabetes ranged from 2 to 17 yr; 5 of the 6 patients had retinopathy as evidenced by fluoroscein angiography (3 with proliferative changes). All 6 patients had a 24-h urinary protein excretion greater than 0.5 g and a glomerular filtration rate less than 80 ml/min. Serum beta 2-microglobulin levels were increased in all 6 patients, while only 3 had increased serum creatinine levels.

Acute insulin response to glucagon, tolbutamide, and glucose in non-insulin-dependent diabetes of the young.

Acute insulin release in response to maximal intravenous doses of glucose (0.5 g/kg), tolbutamide (1 g), and glucagon (1 mg) was studied in 10 subjects with non-insulin-dependent diabetes of the young (NIDDY) and 10 age-, sex-, and weight-matched controls. Diabetic subjects had attenuated insulinemic responses to all three stimuli, in comparison with control subjects. However, insulin responses to glucagon and tolbutamide were higher than those obtained with intravenous glucose. This study demonstrates that the pancreatic beta-cell is more responsive to nonglucose secretagogues than to glucose stimuli in individuals with NIDDY.
