Late development of systemic lupus erythematosus in patients with glomerular "fingerprint" deposits.
Two patients presenting with nephrotic syndrome but without evidence of collagen vascular disease had organized glomerular immune deposits with a "fingerprint" pattern. This finding has been previously associated with lupus nephritis and, in our institution, has been seen in 6% of the biopsy specimens from patients with lupus nephritis. Clinical signs and symptoms of systemic lupus erythematosus in these two patients did not develop until 2 and 5 years later, respectively. The cases of these patients suggest that glomerular deposits with a fingerprint pattern may be a specific marker for lupus erythematosus even when overt clinical features of this disease are lacking. Patients with this finding on renal biopsy should have an extended follow-up for possible development of lupus erythematosus.
