A clinicopathologic autopsy study of the vascular changes in the kidneys of 100 patients with systemic lupus erythematosus was undertaken. Necrotizing arteritis was found in seven patients, mucinous intimal thickening in nine, onion-skin intimal thickening in two, and renal vein thrombosis in two. Active necrotizing arteritis was present most frequently in the arterioles and interlobular arteries, with healing necrotizing arteritis predominating in the arcuate and interlobar arteries. These events were closely related to the activity of glomerular lesions, and immunologic vascular injury seemed to be the causative factor. Rapidly progressive renal failure and severe hypertension had characterized the clinical courses of the patients. Mucinous intimal thickening, present in the arterioles and interlobular arteries, had been accompanied by accelerated hypertension. Although dialysis or accelerated hypertension may have been causes, other factors, including glucocorticoid therapy, must be considered. In one patient with class II lupus nephritis, renal vein thrombosis was considered the cause of the nephrotic syndrome. These vasculopathies, often detected in patients with lupus at autopsy, seem to alter the clinical course.

Human immunodeficiency virus (HIV)-associated lupus-like glomerulonephritis (GN) is a chronic immune complex disease occurring in HIV-infected patients. Although the light, immunofluorescence, and electron microscopy findings indicate features of lupus nephritis, no evidence of systemic lupus erythematosus (SLE) is observed in the affected patients. We present the case of a 45-year-old Caucasian woman with HIV infection who was admitted to the hospital with a nephrotic syndrome 10 years after the HIV diagnosis. A renal biopsy revealed HIV-associated lupus-like GN and necrotizing arteritis affecting two interlobular arteries. Necrotizing arteritis is a type of renal vasculopathy associated with SLE, but has not been reported previously in HIV-associated lupus-like GN. In this case, necrotizing arteritis was found to be a histological feature common to both HIV-associated lupus-like GN and SLE. This histological finding reinforces the resemblance between HIV-associated lupus-like GN and nephritis caused by lupus.
