    Abstract:
    Besides the classic "renal crisis", a well known form of acute renal failure sometimes complicating scleroderma, another type of acute renal injury, even rarer and not well recognized, does exist: a crescentic glomerulonephritis associated with ANCA, and more seldom with anti-GBM antibodies, which is often (but not always) secondary to the use of D-penicillamine. We report the case of a 70 years-old female who presented with a severe acute renal failure accompanied by positive anti-MPO ANCA as well as anti-GBM antibodies. She had a long history of systemic scleroderma which had been treated with D-penicillamine for many years. The clinical picture was typical of an ANCA-positive vasculitis of the microscopic form of polyangeitis, with a crescentic glomerulonephritis on renal biopsy. Unfortunately, the patient died despite therapy with plasma exchanges and immunosuppressive drugs. Some forty cases of crescentic glomerulonephritis associated with scleroderma have been reported. They were initially considered as always associated with D-penicillamine use, but more recently some observations have been made outside this drug context. As will be shown through a literature review, it can be concluded that there are two (or even three according to some authors) forms of acute renal involvement associated to scleroderma, which should be distinguished as soon as possible, given the quite differing therapeutic and prognostic consequences of this distinction.
