**6. Conclusion**

In conclusion, quantitative lipid abnormalities are observed in patients with poorly controlled type 1 diabetes (increased triglyceride and LDL-cholesterol levels) or with microor macroalbuminuria (increased triglycerides and LDL-cholesterol, decreased HDLcholesterol). Patient with optimally controlled type 1 diabetes show normal or slightly decreased triglycerides and LDL-cholesterol levels and sometimes increased HDLcholesterol levels. Qualitative abnormalities of lipoproteins are observed in patients with type 1 diabetes, even in good glycemic control. These abnormalities are not fully explained by hyperglycemia and may partly be due to peripheral hyperinsulinemia associated with the subcutaneous route of insulin administration. The exact consequences of these qualitative lipid changes on the development of cardiovascular disease in type 1 diabetes are still unknown.
