Density results symptoms and conditions

I have now tapered to 10mg prednisone every other day and will end 75mg Cytoxan Aug 19th. Just went to the Dr. and she said protein is back in urine (bad) but also rising in blood. (good) I can continue to taper prednisone but will have to have another 24 hr urine speciman to determine wether I have to go on cyclosporine. Was originally diagnosed with Minimal Change Disease, but now she thinks it could be another kidney disease. Has anyone had successful tapering with the addition of cyclosporine? Does the urine protein ever get higher? What about side effects of cyclosporine.
