I would start with a marrow biopsy and peripheral blood film. If the MCV was elevated, if red cells were dimorphic, or if Pappenheimer bodies or marrow dysplasia were present, I’d start by reducing the zinc therapy. Also, I would measure copper levels, but would need to consult with an expert to interpret the levels in the context of Wilson’s disease.

It would be helpful to know what specific drug the patient is being treated with for his Wilson’s disease. I suspect he is receiving penicillamine, and that this has caused drug-induced lupus and that his pancytopenia is a result of this autoimmune problem. I would switch him to a different drug for copper chelation and possibly treat with immune suppression to reduce the autoimmune issues.

I would advise to perform splenectomy as the patient has hypersplenism, and zinc does not cause neutropenia.

If the patient is on penicillamine, it is possible an agranulocytosis picture. If not, I would put him on folic acid therapy, because a healthy liver is his major reservoir and and blood levels may not reflect its depletion.
