[Hyperhomocysteinaemia and type 2 diabetes].

OBJECTIVES: Hyperhomocysteinaemia is associated with cardiovascular events in nondiabetic individuals. The present study was aimed to explore the implication of hyperhomocysteinemia in development of cardiovascular events in patients with type 2 diabetes.

DESIGN: A total of 185 patients with type 2 diabetes (115 women and 70 men, 30 to 93 years of age) have been included consecutively in the ambulatory unit at the Saint-Philibert Hospital. For each patient the concentration of homocysteine, cholesterol and triglyceride levels and HbA1c have been measured. In the studied population, 121 patients presented cardiovascular events (myocardial infarctus, peripheric arteriopathy, cerebrovascular accident).

RESULTS: The patients with cardiovascular events were older, the concentration of homocysteine and creatinine were higher. The plasma homocysteine levels adjusted for age and creatinine levels were higher in patients with cardiovascular events than in patients without cardiovascular events (15.4 +/- 3.52 micromol/L and 13.13 +/- 2.26 micromol/L respectively; p = 2. 10(-5)).

CONCLUSIONS: Hyperhomocysteinemia is an independant risk factor for cardiovascular events in type 2 diabetes, independent of age and renal function.
