Title: A Randomized Controlled Trial of Pioglitazone on Insulin Resistance, Insulin Secretion and Atherosclerosis in Renal Allograft Recipients Without History of Diabetes
Brief Summary: The aim of this study was to evaluate the effect of pioglitazone treatment on insulin secretion, insulin resistance, and progression of atherosclerosis in renal allograft recipients without preoperative history of diabetes.


Options:
A: Inclusion Criteria:

• Newly diagnosed NODAT defined by pathologic OGTT (2h, 75mg glucose): glucose ≥ 200mg/dl

* renal transplantation (deceased or living donor) and treatment with the standard immunosuppression at our center, consisting of triple therapy with tacrolimus or cyclosporine A, mycophenolate mofetil or azathioprine, and prednisone.

* severe blood glucose elevation with the need for therapy with insulin or HbA1c \>8.5%
B: Inclusion Criteria:

* Patients with type 2 DM who are no longer responsive to maximum dose of one or more oral agents.

Exclusion Criteria:

* Angina pectoris, Canadian Class I-II,
* congestive heart failure, Class III-IV,

* current participation in another clinical trial
C: Inclusion Criteria:

* Renal allograft recipients were eligible to participate in the study if they were aged ≥ 18 years, had no previous history of organ transplantation and were not currently using steroids or other immunosuppressants.

Exclusion Criteria:

* Diabetes before transplantation
* Severe metabolic or infectious disease
* Hepatic disease
* Congestive heart failure (New York Heart Association II-IV)
* Cadaver donor kidney donor transplantation
* Unstable condition of the transplanted kidney
D: Inclusion Criteria:

1. A diagnosis of type 2 diabetes mellitus first made at age 30 years or older
2. Age 55 years or older at entry
3. Ability to provide informed consent
4. A substantially elevated risk of cardiovascular disease, indicated by:

   * A history of major macrovascular disease defined as any one of: stroke, myocardial infarction, hospital admission for transient ischaemic attack, hospital admission for unstable angina, coronary artery bypass graft, percutaneous transluminal coronary angioplasty (with or without stenting), peripheral revascularisation (angioplasty or surgery) or amputation secondary to vascular disease or
   * A history of major microvascular disease defined as any one of nephropathy (albumin:creatinine ratio \>300ug/mg), retinal photocoagulation therapy, proliferative retinopathy (new blood vessels on the disc or elsewhere, vitreous haemorrhage, pre-retinal haemorrhage, or fibrous proliferations on the disc or elsewhere), macular oedema (retinal thickening within one disc diameter of the macular centre) or blindness in either eye (corrected visual acuity 6/60 or worse, persisting for three months or more) not known to be due to non-diabetic causes or
   * A first diagnosis of type 2 diabetes made 10 or more years prior to entry or
   * Another major risk factor for vascular disease defined as any one of: current daily cigarette smoking, total cholesterol greater than 6.0 mmol/l (with or without cholesterol lowering treatment), HDL cholesterol \<1.0 mmol/l, microalbuminuria (albumin:creatinine ratio 30-300ug/mg) or
   * Age 65 years or over

Exclusion Criteria:

1. A definite contraindication to treatment with an ACE inhibitor or a thiazide-like diuretic
2. A specific indication for treatment with an ACE inhibitor other than perindopril 2-4 mg daily (see also section 5.2.3) or a thiazide-like diuretic
3. A definite and specific indication for treatment with gliclazide or a haemoglobin A1c control target of 6.5% or less
4. A definite contra-indication to treatment with gliclazide or a haemoglobin A1c control target of 6.5% or less
5. A definite indication for long-term full-dose or bed-time insulin therapy
6. Participation in a trial within the month prior to the Registration Visit or current participation in another trial

Other potential reasons for ineligibility include:

* High probability of non-adherence to study treatment or follow-up
* Current clinical instability (e.g. a major cerebral or coronary event or sight-threatening retinopathy or macular oedema within the previous few weeks)
* Life threatening non-vascular disease other than diabetes and its complications
* Moderate or severe dementia
* Major disability that is likely to prevent regular attendance at study clinics

Final decisions about eligibility were made at the discretion of the study investigator and the potential study participant, in the light of any requirements or guidance from local ethics committees and other regulatory bodies.
