Some of the treatments for RA cause nutrient depletions.
Some use biological drugs like Enbrel or Humira.
Some use immune modulating drugs like methotrexate.
PN can be autoimmune like RA. It can also be caused by
exposure to some drugs and nutrient deficiencies.
Determination by blood tests can tell alot. But biopsies
tell how much is actually left or lost. So they have their own
merit.
