 This study found that 28.4% of patients developed post-transplant polycythemia after kidney transplantation. Of those with polycythemia, 11 out of 19 patients responded to treatment with angiotensin, converting enzyme inhibitors or angiotensin to receptor blockers, while 8 required phlebotomy. Additionally, 3 patients needed only one phlebotomy, while 5 patients with glomerular filtration rate greater than 30% required multiple phlebotomies.
