A case of lupus nephritis with alteration of the glomerular basement membrane associated with Takayasu's arteritis.

ABSTRACT

A 47-year-old Japanese woman with both Takayasu's arteritis (TA) and systemic lupus erythematosus (SLE) presented with unequal pulses in the upper extremities, diarrhea and proteinuria. In 1986, when she was 38 years old, angiography revealed stenosis of the left subclavian artery. In 1994, SLE was diagnosed on the basis of clinical and laboratory findings, including renal dysfunction, hematologic and immunologic abnormalities, a high titer of antinuclear antibody and a positive lupus band test on the skin. Renal biopsy showed lupus nephritis and glomerular lesions with a bubble-like appearance of the glomerular capillary wall with TA. Lupus nephritis coexisting with glomerulonephropathy associated with TA has rarely been reported.
