Serum cholesterol binding reserve percentage in diabetes mellitus

Serum cholesterol binding reserve percentage (SCBR%) in patients with diabetes mellitus (22.17 +/- 13.40%) was significantly lower than in controls (40.93 +/- 8.69%) (p less than 0.001). SCBR% of controls did not vary with age (age range 20-80 years). SCBR% declined significantly with increasing duration of diabetes. It also decreased with macrovascular complications and was lowest in multiple/fatal complications further corroborating the value of SCBR% as a risk indicator of atherogenesis. The relationship of SCBR% with treatment was very striking. All adequately controlled patients had a significantly higher SCBR% than those who were poorly controlled regardless of treatment modality and those adequately controlled on insulin had the highest SCBR%, which was close to that of normal controls.
