John was treated in 2002 at Johns Hopkins. He participated in a clinical trial for High Dose Cytoxan. It's high doses of the drug for 4 days which basically wipes out your immune system. There are blood stem cells that are not effected which then re-populate the bone marrow. The other two treatments are a bone marrow transplant or immunosuppressant therapy with ATG and Cyclosporine.

It's not treated until it is considered to be severe.

If you are on any drugs, they can impact your blood counts. Statins and anti-biotics can effect blood counts. Also, make sure, if you haven't already, have your B12, folate, iron, vit D, copper and zinc checked. These are the key nutrients for blood production. One other thing. H-Pylori, the bacteria which causes ulcers, can also effect your bone marrow. So get them to test you for that also. You may not have an ulcer, but still have the bug. These are the easy things to rule out up front.
