Renal histological studies in patients with Takayasu's arteritis. Report of 3 cases.
Clinical findings and structural alterations of the kidney in 3 patients with Takayasu's arteritis (TA) and associated glomerulonephritis are described. Clinical evidence of renal disease included persistent proteinuria and microscopic hematuria in all patients. Renal histology showed proliferative glomerulonephritis in 2 of the 3 patients. In 1 patient in whom sequential examination of the kidney was possible, glomerular changes had progressed in severity, in parallel with the expansion of arterial damage of TA. Prednisolone therapy induced a complete disappearance of systemic symptoms of TA and an improvement of proteinuria and hematuria. These findings suggest that TA, which quite possibly results from an immune response to disseminated antigen(s), may occasionally induced glomerulonephritis as a part of its histological expression.
