@ramdem11 welcome to Mayo Clinic Connect. Congratulations on your kidney transplant. I had a pancreas transplant nearly 20 years ago. There were so many post transplant labs at first to watch for any signs of rejection &/or complications. During the first few months post transplant I developed an infection. It was so long ago now I don’t remember what exactly it was. I do remember having a PIC line installed so that vancomycin (sp?) could be administered at home. It took a second surgery (to relocate my transplant - long story) and about 6 more months to resolve. That was a long time ago and a different kind of transplant. What I want to convey is that there’s hope. Dr’s have more experience with kidney transplants. There are lots of ways to test for and treat viruses. Have you asked your provider if there might be a more effective medication to try? How are you tolerating the cidofir IV’s? Have you considered getting a second opinion?
