Immune complex glomerulonephritis in hydralazine-induced SLE.

Renal disease, a major feature of systemic lupus erythematosus (SLE), rarely occurs in drug-induced SLE. Immune complex glomerulonephritis has been demonstrated in a few cases of SLE following procainamide or anticonvulsant therapy but has not been documented in association with hydralazine-induced SLE despite the recognition of this syndrome 30 years ago. We report the clinical and renal pathologic findings in a patient with hydralazine-induced lupus nephritis and review the renal pathologic material in earlier reports of hydralazine-induced SLE.
