Methylprednisolone in patients with membranous nephropathy and declining renal function.

Fifteen consecutive patients aged 24 to 70 years, with membranous nephropathy and a progressive decline in renal function, were treated with methylprednisolone, 1 g intravenously daily for five days, followed immediately by a tapering dose of oral prednisolone. Plasma creatinine levels fell by a mean of 46 per cent (range 21-65). In 10 patients the beneficial effect was sustained, but in three it had reversed by six months. In the other two patients the progressive decline of renal function was not influenced. These observations suggest that many patients with membranous nephropathy and declining renal function could benefit from intervention with high dose steroids.
