Creatinine is at the high end of normal. (Mine is typically at this level with slight kidney damage.) CRP is well within normal. Sedimentation rate is still pretty high. Hope the ultrasound proves negative and they don't have to do a biopsy.

Cytoxan is often used to induce the inital remission (along with high dose steroids). Should be on it no more than 4 - 6 months. Make he stays well-hydrated while on cytoxan and that he urinates whenever he feels the urge as the metabolates of cytoxan are hard on the bladder.
