title: [Renal artery stenosis in patients with type 2 diabetes mellitus: clinical signs, diagnosis, prognostic value].
abstract: OBJECTIVE
  To define the prevalence, clinical features, risk factors, and prognostic value of atherosclerotic renal artery stenosis (RAS) in patients with type 2 diabetes mellitus (T2DM).
  
  
  METHODS
  One hundred and fifty-seven T2DM patients (63 males and 94 females) aged over 50 years were examined. Screening for RAS was carried out by duplex ultrasound scanning (DUSS); the diagnosis was verified by multispiral computed tomography and magnetic resonance imaging. Moreover, the detection rate of RAS was analyzed from the selective angiographic readings of 30 patients with T2DM and 26 coronary angiography patients without DM who had undergone coronary angiography (CA).
  
  
  RESULTS
  In the total group of T2DM patients, the RAS detection rate was 36.9%, as evidenced by DUSS and 43.3% by selective renal artery angiography in the patients who had undergone CA. The factors associated with the development of RAS were smoking (relative risk (RR) = 3.3; p < 0.001); atherosclerosis of coronary (RR = 4.28; p < 0.001) and peripheral (RR = 3.38; p < 0.02) arteries, isolated systolic hypertension (RR = 3.9; p < 0.01), and anemia (RR = 6.4; p < 0.001). In patients with T2DM, RAS was one of the important factors of progressive renal and cardiac diseases and increased mortality determined by the combined end point: death, emergency hospitalization for heart failure, myocardial infarction, double creatinine, and end-stage renal failure (RR = 6.28; p < 0.001).
  
  
  CONCLUSIONS
  The optimization of prognosis in T2DM patients with RAS requires its timely clinical identification in combination with other types of renal lesion, aggressive correction of the mechanisms of the progressive process, and development of medical and endovascular therapies.
