Randomised placebo-controlled trial of effect of ramipril on decline in glomerular filtration rate and risk of terminal renal failure in proteinuric, non-diabetic nephropathy. Much attention has been focused on the complex pathology of lupus nephritis (LN) in an attempt to develop specific therapies targeted to this serious manifestation of systemic lupus erythematosus (SLE). The classification of LN depends on the findings at histology according to the International Society of Nephrology (INS) and Renal Pathology Section (RPS) classification criteria [1] and involves deposition of immunoglobulin in glomerular and tubular basement membrane-enhanced inflammatory response and renal fibrosis [2]. Clinically, proteinuria and haematuria are characteristic features in patients with LN and have traditionally been thought to be the result of immune complex deposition and endocapillary proliferation causing a disruption to the filtration barrier. However, in a subset of protein-uric lupus patients, there is no evidence of the typical immune complexes and instead there appears to be extensive podocyte effacement [3]. The effacement of the foot …
