Characteristics and risk factors of intrarenal arterial lesions in patients with IgA nephropathy

Abstract

The prevalence of small intrarenal arterial-arteriolar lesions was higher in IgAN patients than in non-IgAN and MN patients; moreover, the lesions in IgAN patients were associated with younger age, were more severe and exhibited a higher degree of hyaline changes. Finally, the severity of small arterial- arteriolar lesions was linked to several markers of adverse outcome.
