I'm wondering if any of you have had this experience.
I had a renal transplant 4 1/2 years ago. I have not had any problems and my numbers have been remarkably steady. My creatinine has generally been between 1.10 and 1.20 with my egfr anywhere from 50 to 60. I've never had a rejection episode. At my last annual appointment, my tx neph called me the "poster child for transplantation".
Back in August, my creatinine suddenly rose to 1.33 and my egfr fell into the 40s. I contacted my coordinator who told me that this is not unusual in the summer as it is easy to become dehydrated. She said she has a whole list of patients who she had been calling to reassure them of the same thing. I told her that I had been working (and sweating) exceptionally hard clearing my property, etc., so I felt some relief. I was complety asymptomatic. I felt totally well.
The next set of monthly labs showed my creatinine at 1.46 with a egfr in the low 40s. Panic began to set in despite the fact that my tx team was not unduly worried as they had set my "ceiling" at 1.6. My BUN was elevated, but all of my other numbers (WBC, K, etc) were normal.
Because of my concern, I went back the next week for a creatinine only test, and the results were even worse but were still not 1.6.
I continued pushing fluid, and since I had completed my outdoors work and the weather had finally turned much cooler, I was hoping for better numbers at my next lab appointment with a new order for a whole set of tests.
Before the date of the labs arrived, however, my anxiety level went so high that my bp, normally so well controlled, soared to the point where my ligated fistula arm began to hurt. I went to the ER (it was, of course, a weekend right after Thanksgiving), was treated for both anxiety and high bp and had a set of labs taken.
To my relief, my creatinine was back to 1.3 and my egfr was back into the mid 40s. There was no proteinuria. Pushing fluids as advised seemed to have helped.
I've just received this month's lab results, and my creatinine is still 1.33 with egfr still in the mid 40s. My BUN is normal as is all of my other numbers.
So, my question is this (after all of this blathering, and thank you for reading this far). Why do you suppose that after years of seeing my creatinine at 1.1 to 1.2, I've suddenly had a series of numbers at 1.3? My tx team is not concerned one single bit. I'm no longer concerned but am rather disappointed that this appears to be a new normal. I understand that for a tx patient, there is absolutely nothing wrong with 1.3 especially as my other numbers are fine. My kidney is working well enough which is really all that matters. But still I am curious as to why this change in numbers that have been so steady in the past?
Have any of you experienced "a new normal" like this?
Thank you very much for any thoughts. I appreciate your time.
