Abstract
Renal involvement in Takayasu's arteritis is frequent and worsens the progression of the disease. This is primarily a renal artery stenosis causing renovascular hypertension. The glomerular disease is exceptional. This study was undertaken to determine the clinical, radiological, biological features and therapeutic response in patients with kidney disease associated with Takayasu arteritis. A retrospective chart review was conducted on 11 patients (five men and six females), with a mean age of 31.1 years (19–40 years). The discovery of kidney disease preceded the diagnosis of Takayasu's arteritis in eight cases. Ten patients developed hypertension. Laboratory finding showed proteinuria in five cases of which one case was due to nephrotic syndrome. Renal failure was found in six cases including four cases in stage of terminal chronic renal failure. Impairment of the renal artery was present in nine patients, proximal in seven cases and distal in two cases, bilateral in five cases and unilateral in four cases. Narrowing renal artery was found in seven cases. The renal biopsy revealed membranoproliferative glomerulonephritis in one case and nephrosclerosis in another case. Eleven patients were followed for an average period of 155 months (3–335 months). Remission of nephrotic syndrome was concomitant with the remission of the disease. Seven patients developed outbreaks of Takayasu's arteritis of which six were in care. Relapse of nephrotic syndrome was concomitant with the outbreak of the disease followed by spontaneous remission of both diseases. Improved pressure was obtained in 5 cases and worsening renal function in seven cases. Death was observed in two cases.
