Hi Donna,
Unless liver enzymes are elevated, it sounds like the PSS is now essentially a resolved problem given the normal albumin levels. Since you've also seen improvements in renal function, your treatment so far appears to have been perfect. What I would be watching for is a levelling off in the improvements, or an uptick is the UPC ratio, that signals a need to try a different approach, which would essentially be one of tonification. Since that is a significant departure from the current approach, in terms of hemodynamic effects on the liver and kidney, you would want to reassess liver and kidney indicators a month later or less, to ensure improvements have been seen. If there was any worsening, then you would go back to Harmonize the Qi.
In the meantime, to make sure you have seen the maximum benefits of the anti-inflammatory approach you are using now, you could try either: (1) Benefit Hips and Knees, which is a spin on Harmonize the Qi but with even more potent renal effects, or (2) Three Seeds Combination, which can be used in tandem with either of those previously mentioned formulas.
As to the hypercalcemia, normally we see Harmonize the Qi correct it and not cause it. Perhaps a higher dose might help, or the switch to Benefit Hips and Knees.
The success of the approach you've been using so far indicates an inflammatory renal condition. The chief cause of renal inflammation is processed starch. Using a freeze-dried food that is not too high in protein should continue to support the kidneys by lessening pro-inflammatory pressures on them produced by the k/d, but hopefully be low enough in protein to not have Zoe feeling punky on the diet following consumption. If she maintains her usual energy, then the protein levels are probably not exceeding what the liver can handle.
Hopefully this helps you out. If you get to the point where you need to change from an anti-inflammatory strategy, then given the concomitant PSS and renal disease, I would wonder about Yi Guan Jian. I guess keep that in mind.
Meanwhile, thank you for contributing this case! I have linked your original case report to this question chain, so you can continue the conversation here as you feel the need
