title: [Predictive value of insulin-glucose homeostasis markers in patients with metabolic syndrome X].
abstract: OBJECTIVE
  To clarify informative value of secretory ability of pancreatic beta-cells and correspondence of insulin values to glycemia in the course of standard glucose tolerance test (GTT) in detection of insulin-resistance in patients with arterial hypertension (AH) to verify metabolic syndrome (MS).
  
  
  METHODS
  Correlation and factor analyses were performed of correlations between glycemia, immunoreactive insulin (IRI), C-peptide, glucose/IRI in the course of GTT in 111 AH patients divided into groups by the sum of metabolic disturbances.
  
  
  RESULTS
  The greatest number of correlations were seen for glucose/IRI fasting index. According to the factor analysis, changed sensitivity to insulin and hyperinsulinemia are the first stage of metabolic disturbances in AH irrespective of body mass. In obesity the number of the above correlations is maximal. Multivariance analysis has shown significant differences between AH patients and healthy subjects irrespective of body mass and glucose tolerance.
  
  
  CONCLUSIONS
  Basal index glucose/IRI < 6 relative units is informative in all the studied variants of metabolic syndrome as regards insulin resistance.
