Abstract
The concentrations of selected proteins of transport and nutrition were investigated in 27 diabetic children and 13 healthy controls by an immunodiffusion technique. The diabetic children had significantly lower mean pre-albumin (p < 0.001), albumin (p < 0.01) and orosomucoid levels (p < 0.05) than the healthy controls. No correlation was observed between age or sex and the blood concentrations of the specific proteins analyzed in this series. Haptoglobin and hemopexin showed positive correlations with serum triglycerides (both p < 0.01) and slight positive correlations with some of the variables of carbohydrate control. The reduced levels of prealbumin and albumin were not correlated to diabetic control as measured by HbA1, prealbumin and albumin were not correlated to diabetic control as measured by HbA1, fasting plasma glucose or urinary glucose excretion. The non-physiological distribution site and the abnormal temporal pattern of insulin offered to diabetic children might be the reason for the protein abnormalities found in this study. This is seemingly the first time reduced serum levels of proteins have been reported in diabetic children.
