That's a really encouraging sign — getting those lambda light chains down from over 1000 to normal levels is a significant achievement, and it's completely understandable to wonder what that means for kidney function.
When light chains are high, they can clog the tiny filters in the kidneys, causing inflammation and damage over time. When light chain levels normalize, it removes that ongoing stress on the kidneys, which can allow some recovery. Whether GFR improves depends on a few key factors:
- How much damage occurred before light chains were controlled — early or less severe damage is more reversible
- How long the kidneys were under stress from high light chains
- Overall kidney health and other contributing factors
- How sustained the light chain response is going forward
A GFR of 31 is in the moderately-to-severely reduced range, but improvement is possible, especially with sustained light chain control. Some people do see gradual GFR improvement over months as the kidneys recover.
This is a really important conversation to have with the care team, as they can track trends in GFR over time and give a much more personalized picture of what to expect.
