In a prospective study of South African Indians with impaired glucose tolerance (IGT), the serum insulin response during a 75 g oral glucose tolerance test (OGTT) was examined in 128 subjects who were classified as IGT 1 year previously (year 0) and in 60 matched control subjects. Based on the results at year 1, study subjects were divided into three groups, using World Health Organization criteria for glucose tolerance: IGT (n = 47), diabetes (n = 41), and transient IGT (normal glucose tolerance) (n = 40). When compared with the control group, despite higher plasma glucose concentrations, the IGT group showed similar fasting insulin, but lower 30-min insulin response (57.4 +/- 1.9 mUl-1 vs 86.5 +/- 1.8, p < 0.001) and lower 30-min insulin/glucose ratio (7.4 +/- 5.2 vs 13.3 +/- 8.7, p < 0.001). The insulinogenic index was lower in the IGT group than in the control group at 30, 60, 90, and 120 min (p < 0.01, p < 0.001, p < 0.001, p < 0.001, respectively). The 2-h insulin response was higher in the IGT group (106.7 +/- 1.9 mUl-1 vs 59.2 +/- 1.9, p < 0.01). The IGT group displayed a delayed pattern of insulin response with maximum levels only at 2-h. Insulin area was similar in the two groups. In the transient IGT group, despite similar plasma glucose levels, the insulin responses at 0, 15, 30, and 60 min (p < 0.01, p < 0.001, p < 0.001, p < 0.001, respectively) were lower than in the control group; the 30-min insulin/glucose ratio (7.1 +/- 5.1 vs 13.3 +/- 8.7, p < 0.001) and 60-min insulinogenic index (46.9 +/- 86.3 vs 123.4 +/- 206.3, p < 0.001) were also lower in the transient IGT group.(ABSTRACT TRUNCATED AT 250 WORDS)
