BILATERAL RENAL ARTERY STENOSIS IN A HYPERTENSIVE LUPUS PATIENT WITHOUT RENAL DYSFUNCTION

0

Systemic lupus erythematosus (SLE) is associated with a high prevalence of atherosclero-sis and an enhanced cardiovascular mortality. In adult subjects, several studies have shown the coexistence of SLE and renal artery stenosis, most of them with unilateral in-volvement or with renal dysfunction.
We observed a 62-year-old man with SLE and a 10-year history of moderate-to-severe hy-pertension who was admitted to our hospital because of uncontrolled blood pressure val-ues (152/95 mmHg), despite drug therapy. No signs of renal impairment were evident.
After an initial physical examination, which presented a periumbilical bruit, a renal ultra-sound was performed with evidence of bilateral renal artery stenosis. An angio-MR study also confirmed the diagnosis and showed a double renal artery on the right side.
Many different factors can contribute to the bilateral renal artery stenosis in this patient. Chronic inflammatory state associated to SLE, metabolic alterations with dyslipidemia and steroid therapy may all be involved in the development of the renal atherosclerotic le-sions.
