My guess is Parvo B-19 is responding as an opportunistic infection in Lyme patients. If our defenses are down, it pops up its ugly head and maybe then readings show on tests, perhaps along with some symptoms. ???
At the bottom of the Parvo page linked above are abstracts. One said...
"After a disease course of 9 months one patient could be classified as rheumatoid arthritis in the presence of anti-cyclic citrullinated antibodies but lack of rheumatoid factor. One patient with polyarthritis developed psoriasis of the skin 22 months later.
From the nine patients with unclassified arthritis 4 (45%) got into complete remission with no symptoms or signs of joint inflammation after a disease course of 9-45 months, whereas 5 (55%) still demonstrate active non erosive arthritis (disease duration between 3 and 10 years)."
There are more articles there, but I am short on time and very short on brain power! HA!
