Diabetes Mellitus, Type 2
Conditions
Brief summary
Primary objective: To evaluate in explorative manner the fasting blood glucose (FBG) coefficient of variability (CV)calculated on SMBG values (SMBG : Self-Monitoring of Blood Glucose). Secondary objectives: The secondary objectives are the assessment of: changes in glycaemic control (HbA1C), frequency of hypoglycaemias, changes in weight, final insulin dose, changes in lipid parameters, changes in urinary albumin-to-creatinine ratio, profile of patient which best fits each of the algorithms with the dependent variable of change in HbA1C and independent variables of age, gender, race, tobacco use, diabetes complications, initial HbA1C, initial weight, duration of diabetes mellitus, general education and diabetes education.

Inclusion criteria
* Diagnosis of type 2 diabetes mellitus for at least 5 years; * Treatment with oral antidiabetic drugs in fixed combination (Combo, i.e. glibenclamide 2.5 mg + metformin 400 mg, 2 or 3 tablets, at stable dose in the last 3 months); * HbA1c \>= 8% and \<= 11%; * Body mass index (BMI) \> 27 and \< 35 kg/m2; * Willingness and demonstrated ability to inject insulin; * Demonstrated ability and willingness to perform self-monitoring of blood glucose (SMBG);
Exclusion criteria
