To the Editor: The perfusion nephropathy in human transplants described by Spector et al. (N Engl J Med 295:1217–1221, 1976) is morphologically very similar to the glomerular lesion attributed to steroids in canine homografts and autografts.1,2 Both have diffuse eosinophilic material within glomerular loops and a similar appearance on light microscopy at one to two hours. Since methylprednisolone (120 mg) was added to the perfusate in all the perfused donor kidneys reported by Spector and his colleagues, it is possible that this agent was responsible for the pathologic lesion and the decreased graft survival. The dose of methylprednisolone in.
