Correct Answer: diffuse proliferative GN
Description: Systemic lupus erythematosus (SLE) can cause a wide variety of renal disorders, and can progress to ESRF. Because of the active urine sediment this individual has a proliferative GN. It is difficult to diagnose the type of glomerular involvement in SLE without a biopsy. Based on the biopsy results lupus nephritis (LN) is divided into 6 classes (WHO classification). Class I, minimal mesangial LN; Class II, mesangial proliferative LN; Class III, focal LN; Class TV, diffuse segmental LN; Class V, membranous LN; and Class VI, advanced sclerosing LN.
