title: The serum amino acid spectrum of insulin-dependent diabetics and controls from Ethiopia.
abstract: The serum amino acid spectrum was examined in healthy men and insulin-dependent diabetics from Ethiopia. Comparison of serum amino acids of controls from Gondar with Ethiopians after adaptation to a free European diet revealed a marginal low protein nutrition, but not the characteristic changes of malnutrition or experimental starvation. There was no apparent nutritional deficiency of sulphur-containing amino acids in Ethiopians. Insulin-dependent diabetics showed significantly elevated serum levels of BCAA indicating an accelerated protein catabolism in recent-onset insulin-deficient patients and known diabetics respectively, most of them in poor metabolic condition. Serum glutamine levels were reduced, suggesting a considerable renal contribution to the hyperglycaemia/glucosuria of diabetics. The data may be best explained by the low residual insulin secretion at diabetes onset or by the poor degree of metabolic control of known Ethiopian diabetics.
