Title: (Intervention Study) A Randomized Controlled Study of the Intensive Therapy and the Conventional Therapy for the Suppression of the Vascular Complications in the Type 2 Diabetic Patients (Follow-up Study) A Randomized Controlled Study Comparing Intensive Therapy and Conventional Therapy in the Reduction of Vascular Complications in Type 2 Diabetic Patients: A Follow-up Study After Intervention
Brief Summary: (Intervention study) The objective of the study is to confirm the superiority of the intensive therapy to the conventional therapy concerning the prevention of the incidence or exacerbation of vascular complications caused by diabetes mellitus (DM) by a randomized controlled study in patients with type 2 DM.

(Follow-up study) The objective of the follow-up study is to evaluate the long-term efficacy of intensive versus conventional therapy in the effect on mortality and the prevention of the incidence or exacerbation of vascular complications caused by diabetes mellitus through a post-intervention follow-up research conducted after the multi-center, open-label, randomized parallel-group study comparing the efficacy of intensive versus conventional therapy in type 2 diabetic patients.


Options:
A: (Intervention study)

Inclusion Criteria:

Subjects were considered eligible if they were 45 years old or older but younger than 70 years old at study entry, had type 2 diabetes and met both "(1) and (2)" or both "(1) and (3)" described below. \[Note: Those who met all three "(1), (2) and (3)" were also considered eligible for inclusion.\](1) Glycemic control Those with HbA1c 6.9% or greater despite treatment with any of the three regimens given below. Diet and exercise therapy alone, Diet and exercise therapy plus 1 oral anti-diabetic drug, Diet and exercise therapy plus, GI and 1 other oral anti-anti-diabetic drug (2) Blood pressure control Those with the following casual blood pressure (BP) level as measured on an outpatient basis, Systolic BP 140 mmHg or diastolic BP 90 mmHg while not on an antihypertensive agent, Systolic BP 130 mmHg or diastolic BP 80 mmHg while on 1 or 2 ARB, ACEI or long-acting CCB Those receiving antihypertensive agents other than ARB, ACEI or long-acting CCB were not eligible for study entry, with the exception of those who were receiving these agents for other purposes than blood pressure lowering. (3) Lipid metabolism Those with the following fasting lipid levels while not on a lipid-lowering agent LDL-cholesterol, 120 mg/dL (as calculated by using the Friedewald formula) Triglycerides, 150 mg/dL HDL-cholesterol, \< 40 mg/dL Subjects receiving 1 lipid-lowering agent were judged eligible for study entry if they met any of the above criteria. However, care needs to be taken to ensure that those on fibrates discontinue the fibrate treatment at the start of the study when they are assigned to the intensive therapy arm.

Exclusion Criteria:

1. Those with poorly controlled hypertension despite pharmacological therapy (systolic BP 200 mmHg or diastolic BP 120 mmHg) 2. Those on insulin therapy 3. Those with non-diabetic renal disease 4. Those in whom type 1 and other diabetes due to pathogenic mechanisms other than those associated with type 2 diabetes is strongly suspected 5. Those who tested anti-GAD antibody\*-positive 6. Those with LDL-cholesterol 200 mg/dL 7. Those suspected of having secondary hypertension other than renal parenchymal hypertension 8. Those suspected of having hereditary lipid disorder with a strong family history of lipid metabolic disorder 9. Those who were receiving antihypertensive agents other than ARB, ACEI, long-acting CCB, except where they were receiving these agents for other purposes than blood pressure lowering 10. Those who were receiving 3 or more antihypertensive agents (i.e., ARB, ACEI, and long-acting CCB), except where they were receiving these agents for other purposes than blood pressure lowering 11. Those with more serious retinopathy than proliferative retinopathy 12. Renal failure (serum Cr: 2.0 mg/dL in men; 1.5 mg/dL in women) 13. Those with a history of cardiac failure or those with cardiac failure 14. Those who were pregnant or potentially pregnant 15. Those who met any of the following criteria and who had BNP 100 pg/mL, Myocardial infarction, Angina pectoris (or a history of disease), History of coronary artery bypass graft (CABG), History of percutaneous coronary angioplasty (PTCA), Other cardiac disease, ECG findings of left ventricular hyperplasia, Abnormal ECG findings (excluding isolated extrasystole or right bundle branch block \[RBBB\]) 16. Those judged by the physician in charge to be ineligible for study entry

(Follow-up study)

Inclusion criteria:

Of the subjects in the randomized controlled study comparing intensive therapy and conventional therapy in type 2 diabetic patients (J-DOIT3), those who provide written informed consent to participate in the follow-up study will be enrolled regardless of completion or discontinuation from the randomized controlled study (If the subject is unable to provide informed consent for any reason, consent from his/her legal representative is allowed).
