OBJECTIVE To summarize the clinical presentation, histological features, treatment, and outcome of minimal change nephropathy (MCN) in patients with systemic lupus erythematosus (SLE). METHODS We performed a systematic review of cases of MCN in SLE patients reported in the English literature from January 1985 to May 2009 by a Medline search. RESULTS The estimated prevalence of MCN in biopsy-proven lupus nephritis is 2.3% in childhood and 1.1% in adults. There are 13 individual cases (12 women, one man) of SLE-related MCN reported in the literature. The mean age of nephritis onset was 32.7 years. In six (46%) patients, MCN was the initial manifestation of SLE. All patients presented with nephrotic syndrome and two (15%) had active urinary sediments. Renal function was impaired in eight (62%) patients and six (46%) patients had active lupus serology. All patients responded promptly to high-dose glucocorticoids but four (31%) had relapse of proteinuria during their course of SLE. None of the patients developed thromboembolic or infective complications. CONCLUSIONS MCN is an uncommon histological class of lupus nephritis. Typically, patients present with heavy proteinuria, and transient renal dysfunction is common. The prognosis of MCN in SLE appears to be good because of its rapid response to glucocorticoids. Relapses of proteinuria may be reduced by the use of maintenance immunosuppression. Alkylating agents, calcineurin inhibitors, mycophenolate mofetil, and rituximab can be considered in glucocorticoid-dependent or refractory cases of SLE-related MCN.

D008181 Lupus Nephritis Glomerulonephritis associated with autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Lupus nephritis is histologically classified into 6 classes: class I - normal glomeruli, class II - pure mesangial alterations, class III - focal segmental glomerulonephritis, class IV - diffuse glomerulonephritis, class V - diffuse membranous glomerulonephritis, and class VI - advanced sclerosing glomerulonephritis (The World Health Organization classification 1982).

D009402 Nephrosis, Lipoid A kidney disease with no or minimal histological glomerular changes on light microscopy and with no immune deposits. It is characterized by lipid accumulation in the epithelial cells of KIDNEY TUBULES and in the URINE. Patients usually show NEPHROTIC SYNDROME indicating the presence of PROTEINURIA with accompanying EDEMA.

D050527 Mesangial Cells Smooth muscle-like cells adhering to the wall of the small blood vessels of the KIDNEY at the glomerulus and along the vascular pole of the glomerulus in the JUXTAGLOMERULAR APPARATUS. They are myofibroblasts with contractile and phagocytic properties. These cells and their MESANGIAL EXTRACELLULAR MATRIX constitute the GLOMERULAR MESANGIUM.
