Title: Diabetes Control and Complications Trial (DCCT)
Brief Summary: Background. Long-term microvascular and neurologic complications cause major morbidity and mortality in patients with insulin-dependent diabetes mellitus (IDDM). We examined whether intensive treatment with the goal of maintaining blood glucose concentrations close to the normal range could decrease the frequency and severity of these complications.

Methods. A total of 1441 patients with IDDM -- 726 with no retinopathy at base line (the primary-prevention cohort) and 715 with mild retinopathy (the secondary-intervention cohort) were randomly assigned to intensive therapy administered either with an external insulin pump or by three or more daily insulin injections and guided by frequent blood glucose monitoring or to conventional therapy with one or two daily insulin injections. The patients were followed for a mean of 6.5 years, and the appearance and progression of retinopathy and other complications were assessed regularly.


Options:
A: Inclusion Criteria:

* Type 2 diabetes
* Microalbuminuria

Exclusion Criteria:

* Stimulated serum C-peptide concentration less than 600 pmol/L
* Pancreatic insufficiency or diabetes secondary to pancreatitis
* Alcohol abuse
* Non-diabetic kidney disease
* Life-threatening disease with death probable within 4 years of study start
B: Inclusion Criteria:

* Participated in ADVANCE
* Ability to provide informed consent

Exclusion Criteria:

* None
C: Eligibility Criteria:

* The major criteria for eligibility included insulin dependence, as evidenced by deficient C-peptide secretion; an age of 13 to 39 years; and the absence of hypertension, hypercholesterolemia, and severe diabetic complications or medical conditions. To be eligible for the primary-prevention cohort, patients were required to have had insulin dependent diabetes mellitus (IDDM) for one to five years, to have no retinopathy as detected by seven-field stereoscopic fundus photography, and to have urinary albumin excretion of less than 40 mg per 24 hours. To be eligible for the secondary-intervention cohort, the patients were required to have IDDM for 1 to 15 years, to have very-mild to moderate nonproliferative retinopathy, and to have urinary albumin excretion of less than 200 mg per 24 hours.
D: 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,
* stroke, incapacitating or in last 6 months,
* Myocardial infarction (MI) or invasive cardiovascular procedure within the past six months,
* ongoing diabetic gangrene,
* BMI \> 40,
* hemoglobinopathy that interferes with A1c monitoring,
* serum creatinine \> 1.6 mg/dL,
* fasting C-peptide \< 0.21 pmol/ml,
* Alanine Amino Transaminase (ALT) \> 3 times normal or serum bilirubin \> 1.9 mg/dL,
* malignancy or noncardiac life-threatening diseases making life expectancy \< 5 years,
* autonomic neuropathy,
* symptomatic pancreatic insufficiency (endocrine or exocrine),
* recurrent seizures within the past year,
* hypopituitarism,
* pregnancy, lactation, or planning a pregnancy,
* active psychosis or substance abuse,
* lack of access to a person who can assist or be called in an emergency,
* underlying conditions that in the site PI's judgment may prevent adherence to protocol,
* current participation in another clinical trial
