  • Title: Peculiar glomerular lesions in Takayasu's arteritis.
    Author: Yoshimura M, Kida H, Saito Y, Yokoyama H, Tomosugi N, Abe T, Hattori N.
    Journal: Clin Nephrol; 1985 Sep; 24(3):120-7. PubMed ID: 2864151.
    Abstract:
    Seventeen kidney specimens (6 biopsies and 11 autopsies) of Takayasu's arteritis disclosed two types of glomerular lesions. One was a mild axial mesangial proliferation associated with intramembranous and mesangial electron dense deposits consisting of IgG, IgM and C3 (axial type). The other was a centrolobular mesangial thickening associated with a hyaline deposition showing a mosaic pattern ("centrolobular mesangiopathy": centrolobular type). Mesangiolytic lesions, nodulous lesions, microaneurysms in glomeruli and extensive deposition of hyaline materials both in afferent and efferent arterioles were also observed. The former lesion was found in 4 patients with an active arteritis; and the latter was mainly observed in autopsy cases having a long-term clinical course. In the genesis of the axial type, immune complex deposition caused by the active aortitis may be involved, while the glomerular ischemia caused by the vascular lesions may be implicated in the development of the centrolobular type.
