Paper Abstract

The concept that free radicals mediate vascular abnormalities in diabetes has been debated. This study examines the relationship between serum free radical activity and glycaemic regulation. A cross-sectional assessment is presented of the chemiluminescence of blood serum, long term glycaemic control (HbAlc, fructosamine) and blood glucose concentrations in patients with type-1 (n equals 114) and patients with type-2 (n equals 112) diabetes. The average value of serum chemiluminescence of type-1 patients is higher than that of type-2 patients (p equals 0.014). Spectral analysis suggests that different sources of free radical activity are responsible in different ratios for chemiluminescence in type-1 and type-2 sera. Serum chemiluminescence values of type-1 patients strongly correspond with blood glucose levels (p < 0.001). Chemiluminescence values were higher, although not significant (p equals 0.082) in the 'poorly' controlled group characterized by high values of HbAlc and/or fructosamine in comparision with the group of 'good' glycaemic control with lower values of HbAlc and/or fructosamine. Serum chemeluminescence values of type-2 patients neither correspond to their long tern glycaemic status nor to their blood glucose levels. It is concluded that changes in glucose metabolism and changes in chemiluminescence are coordinated for type-1 but not for type-2 patients. This strongly indicates the relevance of ther free radical connection to diabetes type-1 complications.
