Hi Neo! I am not sure what your circumstances are, but my younger brother had his transplant almost 8 years ago. His creatinine right after transplant got down to 0.9/1.0. After about a year, his numbers started climbing. He had a biopsy, but didn't show signs of rejection. He did develop the BK virus, but after several months of treatment, his numbers went down and they stopped his leflunomide sp?. His current creatinine numbers range from 1.9 to 2.2. He says he feels great and he only sees his neph every six months for blood work. The general consensus from his transplant team is that this is where his "normal" should be. He is a very big guy (6'9" and 275 pounds). He had a cadaveric transplant, and the doctors think his kidney was possibly from a smaller person. Not sure that any of this makes sense, but know that he is doing amazingly well. I guess the numbers don't always signal a real problem, but I am sure your transplant team will want to investigate further. Hang in there! It's probably nothing! Hope everything checks out fine!
