>they were mostly from autoimmune diseases that couldn’t plausibly be related to their donations
Sounds extremely brittle logic. Why couldn't they be "related to their donations"?
For starters, the donations could make their immune system weaker (and thus make any autommune diseases they already have more impactful) or make it go haywire to combat the post-operation stress...
The idea "the donations could make their immune system weaker" seems pretty brittle. Why? What biological mechanism would support that hypothesis? What kidney function that would be halved (assuming the remaining kidney wouldn't "step up" to fill the gap) that could lead to an autoimmune disorder?
Not saying there's nothing, but you haven't provided any more evidence or logic than OP has provided.
