Development of focal segmental glomerulosclerosis in the renal allograft of a patient with lupus.
Nephritis has been a recognized complication of systemic lupus erythematosus since the early 1900s. Almost all lupus patients have some degree of renal involvement related to their condition, but a considerably smaller proportion of these patients actually progress to end-stage renal disease (ESRD). However, lupus patients are also susceptible to other primary renal insults that may significantly contribute to the deterioration in their renal function. We present a case of a patient with clinical and pathological evidence of lupus nephritis that progressed to ESRD and subsequently developed "recurrent" focal segmental glomerulosclerosis in her transplant kidney. Retrospective clinicopathologic correlation suggested the possibility of more than 1 primary renal process that eventually led to her dialysis-dependent state. This case illustrates the importance of meticulously examining both clinical and renal biopsy data in patients with lupus nephritis and considering the presence of co-existing renal pathologies to resolve an otherwise discordant picture of disease progression. These considerations may have important therapeutic and prognostic implications.
