What autoimmune disease causes high vitamin B12?

Autoimmune Lymphoproliferative Syndrome (ALPS) is a key autoimmune disorder linked to significantly high B12 levels, as is systemic lupus erythematosus (SLE) or Still's disease, where inflammation increases B12-binding proteins like haptocorrin from immune cells. The elevation often results from increased production of these binding proteins by activated immune cells, not necessarily excess intake, though other issues like liver disease or blood cancers can also elevate levels.
