  • Title: Glomerular lesions in benign essential hypertension. A study of eight biopsy specimens with laboratory evidence suggestive of glomerular abnormalities.
    Author: Katz SM, Lavin L, Swartz C.
    Journal: Arch Pathol Lab Med; 1979 Apr; 103(4):199-203. PubMed ID: 581847.
    Abstract:
    We performed renal biopsies on eight patients who had benign essential hypertension but laboratory abnormalities suggestive of glomerulonephritis. Persistent microscopic hematuria was detected in four patients, proteinuria in five, RBC casts in two, and decreased glomerular filtration in seven. In all eight biopsy specimens, we detected hyaline arterionephrosclerosis, focal glomerular obsolescence, and segmental, afibrillar thickening of glomerular basement membranes. Direct immunofluorescence studies performed on all eight samples were negative for immunoglobulins, complement, and fibrinogen. Although the patients in our study had laboratory findings suggestive of glomerulonephritis, the morphologic changes were indicative of benign essential hypertension.
