title: Relationship of elevated osteoprotegerin with insulin resistance, CRP, and TNF-alpha levels in men with type 2 diabetes.
abstract: OBJECTIVE
  Our objective of this study is to investigate the relationship between plasma osteoprotegerin (OPG) levels in type 2 diabetes and its relationship with the insulin resistance, HbA(1c), CRP, and TNF-alpha levels.
  
  
  METHODS
  In a cross-sectional study, levels of OPG were determined in 50 subjects with type 2 diabetes and 59 control subjects without diabetes. The OPG levels between the groups were compared and their correlation with insulin resistance, glycemia and inflammatory markers CRP and TNF-alpha was determined.
  
  
  RESULTS
  OPG levels were elevated in subjects with diabetes (6.8+/-0.27 pmol/l), compared to control subjects (5.7+/-0.26 pmol/l). OPG levels significantly correlate with insulin, insulin resistance, CRP, and TNF-alpha.
  
  
  CONCLUSIONS
  OPG levels are significantly correlated with insulin resistance and may reflect the proinflammatory state in type 2 diabetes.
