title: Insulin-dependent ketosis-resistant diabetes in Ethiopia.
abstract: Anthropometric, clinical and biochemical findings were compared in 30 rural (group A), 18 urban insulin-requiring (group B) and 45 urban oral-agent-responsive (group C) newly diagnosed diabetics. Mean ages at onset were 28.3 +/- 12.0, 25.6 +/- 14.5 and 42.1 +/- 10.5 years respectively. The differences between A and C and between B and C were significant. Group A were poor and malnourished, with body mass index (BMI) 15.9 +/- 1.9 and 17.2 +/- 3.7 kg/m2 for males and females respectively, presented with a long history of classical diabetes without ketoacidosis and required insulin in modest doses. 3 of 10 cases had excess stool fat but none of 13 unselected cases had pancreatic calcification. Group C were better nourished, with BMI 22.6 +/- 2.8 and 22.4 +/- 4.5 kg/m2, and responded to oral agents. Group B, with BMI 17.2 +/- 2.6 and 18.6 +/- 3.1 kg/m2, required insulin for control but had C-peptide levels above 0.02 nmol/1 in 10 of 15 cases. Anthropometric indices for males, but not for females, were significantly lower in group A than in group B or C. There were significant differences in levels of glucose between A and B and A and C, free fatty acids between A and C and B and C, insulin between A and B and A and C and C-peptide between A and C and B and C. Of the 3 groups the rural type most closely resembled the tropical variants.
