I had my weekly creatinine level check today. Unfortunately it did go up (instead of down) but only by 12 points. So while the increase was not terribly significant, it has gone in the wrong direction this week.
It is quite possible (because it is not an exact science) that my current lower dose of steroids might not be sufficiently suppressing my immune system, which would allow the immunotherapy to continue to damage my kidneys a bit. It is also possible the increase in creatinine is being caused by something else (medication, dehyrdration, etc.)
However, the Oncologists believe it's likely the tapering off of the steroids has made the current dose too low to continue to shut down the immunotherapy. They will move me back up a bit on steroids, and retest in a week. If my creatinine goes down, it was likely a dosing issue with the steroids.
So, not a terrible creatinine report, but we need to get back on track now.
