title: [Contribution of irreversible morphological changes of different renal structures to development of anemia in immune glomerulopathies].
abstract: OBJECTIVE
  To find out correlations between severity of sclerotic affection of the glomeruli, tubules, interstitium, vessels and development of anemia in patients with glomerulopathy.
  
  
  METHODS
  Assay of global and segmentary sclerosis, semiquantitative morphometry of severity of atrophic tubular changes, diffuse interstitial fibrosis, vascular changes (arteriolohyalinosis, elastofibrosis and perivascular sclerosis) were made in parallel with analysis of clinical laboratory data in 276 cases of chronic primary glomerulopathy with morphologically verified diagnosis by vital renal biopsy.
  
  
  RESULTS
  Hemoglobin concentration and advance of anemia correlate negatively with severity of diffuse interstitial fibrosis and atrophic tubular alterations. However, no correlation was found between onset of anemia, severity of global and segmental glomerular sclerosis, the presence of vascular changes in the form of arteriolar hyalynosis, elastofibrosis of small arteries and perivascular sclerosis.
  
  
  CONCLUSIONS
  The findings suggest that development of anemia in patients with primary glomerulopathy may be the result of structural-functional disturbances in tubular epithelium and renal stroma.
