  • Screening for Hypertension [ Time Frame: At recruitment ] [ Designated as safety issue: No ]
    • Blood pressure measurement by electronic tensiometer (OMRON4) on right and left arms, after 10 mn of supine position.
    • Three measures are performed with respect of one minute interval between each measure.
    • Mean blood pressure is calculated
    • Three other measures are performed in ulterior consultations

  • Screening for silent myocardial ischemia [ Time Frame: At recruitment ] [ Designated as safety issue: No ]
    • 9 derivations resting electrocardiogram (ECG)
    • Echocardiography
    • Standard ECG stress test
    • Stress Myocardial Perfusion scintigraphy if patients are not able to perform ECG stress test
    • Coronary angiography if exercise ECG test or stress myocardial perfusion scintigraphy suggest high risk coronary heart disease

  • Screening for lower extremity artery Disease [ Time Frame: At recruitment ] [ Designated as safety issue: No ]
    • Complete vascular examination with Ankle-Brachial Index measure.
    • Lower limb duplex ultrasonography

  • Screening for carotid artery disease [ Time Frame: At recruitment ] [ Designated as safety issue: No ]
    • Screening for carotid murmur
    • Carotid duplex ultrasonography with intima-media thickness measurement

  • Screening for renal artery stenosis [ Time Frame: At recruitment ] [ Designated as safety issue: No ]
    - Renal artery duplex ultrasonography if resistant hypertension

  • Screening for cardiac autonomic Neuropathy [ Time Frame: at recruitment ] [ Designated as safety issue: No ]
    • Conditions: fasting, resting at least 30mn, no hypoglycemia and no effort within 24hours, no drugs that interfere with heart rate.
    • Ewing Tests for cardiac autonomic neuropathy: Beat-to-Beat heart rate variation, Heart rate response to standing, Heart rate response to valsalva maneuver, Systolic blood pressure response to standing.

  • Screening for Bladder autonomic neuropathy [ Time Frame: at recruitment ] [ Designated as safety issue: No ]
    • History of recurrent urine tract infection and/or dysuria and/or incomplete bladder emptying
    • Post voiding residual(PVR) measurement with abdominal echography.
    • Cystomanometry is performed if PVR > 50 ml

  • Screening for gastro-intestinal autonomic neuropathy [ Time Frame: at recruitment ] [ Designated as safety issue: No ]
    • History of post prandial discomfort or bad gastric emptying sensation or vomiting or unexplained diarrhea or constipation
    • Endoscopic examination is performed to exclude other causes than gastro-intestinal autonomic neuropathy

  • Screening for erectile dysfunction [ Time Frame: at recruitment ] [ Designated as safety issue: No ]
    - Questionary: onset , drug use, medical history, psycho- social conditions

Secondary Outcome Measures:
  • Screening for new cardiac events [ Time Frame: One year after recruitment ] [ Designated as safety issue: No ]
    • Record every documented acute coronary syndrome during follow-up
    • Electrocardiogram
    • Echocardiography

  • Screening for new stroke or Transient ischemic attack [ Time Frame: One year after recruitment ] [ Designated as safety issue: No ]
    • Clinical signs of stroke.
    • Tomodensitometry or magnetic resonance imaging.

  • Screening for lower limb atherothrombotic accident [ Time Frame: One year after recruitment ] [ Designated as safety issue: No ]

    - Record each death and its cause

Biospecimen Retention:   Samples Without DNA

Blood. Urines. Tissue (kidney) for few patients.

Enrollment: 327
Study Start Date: January 2009
Study Completion Date: December 2014
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Complications,no specific treatment
After screening for complications, a non specific multi interventional treatment is applied to patients. After one year of follow up, we will compare two groups: with and without chronic kidney disease, on the advent of cardiovascular events. An adjustment is done for age and major risk factors.
Other: no specific treatment
lifestyle counseling, antihypertensive drugs, antidiabetic drugs (oral and / or insulin)treatment of comorbidity or complications of diabetes.

Ages Eligible for Study:   40 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Population of type 2 diabetes patients that diabetes is diagnosed recently, in one of the health structures, in the east suburban area of Algiers. In the first step they are recruited by primary care physicians, on the basis of glycemia >= 1.26 g/l (capillary or venous); then they are automatically directed to the main investigator, in hospital consultation, to confirm by two blood samples, the hyperglycemia; and (second step) screen for differential diagnosis (secondary diabetes)before the definitive recruitment.Patients are systematically,consecutively recruited. They are followed up during 1 year, they are seen every 3months at least.


Inclusion Criteria:

  • Men or women aged from 40 to 70 years
  • Newly diagnosed type 2 diabetes
  • Never treated for diabetes

Exclusion Criteria:

  • Gestational diabetes
