Dr. Richard Horowitz M.D. comments on UC Davis Lyme findings

FYI  Posted by Karla:
--------------------------------------
On his Facebook page, Dr. Horowitz explains why important new research from UC Davis may explain why many Lyme patients may continue to demonstrate a positive IgM profile and fail to develop a positive IgG profile. This is contrary to the current recommendations of the IDSA, the CDC, and the NYS DOH to physicians to ignore all positive B. burgdorferi IgM profiles after one month of illness.

Suppression of Long-Lived Humoral Immunity Following Borrelia burgdorferi Infection:

Dr. Horowitz: "Borrelia burdorferi has developed one more strategy to evade the immune system. Nicole Baumgarth and her colleagues at the University of California, Davis, just published a groundbreaking study showing why some people living in endemic areas can continually be exposed to spirochetes and not clear the infection with an adequate immune response. According to the study done in mice, borrelia is able to rapidly invade the lymph nodes, and cause a destruction of the distinct architecture of the lymph node that helps it to function normally. "While B cells accumulated in large numbers and made some specific antibodies against B. burgdorferi, they did not form "germinal centers", structures that are needed for the generation of highly functional and long-lived antibody responses". Borrelia also subverted a B cell response (B cells produce antibodies to fight infection), and instead, caused T cell independence, leading to an IgM skewed profile (in our practice, we often see many more IgM positive Western blots in patients with chronic persistent Lyme, as opposed to IgG positive Western blots). These findings suggest that "B. burgdorferi hinders the immune system from generating a response that is fully functional and that can persist and protect after repeat infections", and suggests a novel evasion strategy for B. burgdorferi by subverting the quality of a strongly induced, potentially protective borrelia-specific antibody response."

More important information from Dr. Horowitz in the comments section of his Facebook post:

Dr. Richard Horowitz - I'm looking into pulsing antibiotics and persister drugs (like those used for TB and Hansen's disease) in Lyme. We are presently accumulating data, but some of the results have been very encouraging in resistant patients. I presented preliminary data last weekend at Omega. When the studies are completed, I will share them at the upcoming Lyme conference at Kripalu in December. http://kripalu.org/presenter/V0008603/richard_horowitz

  1. For years,Kathleen M Dickson,one angry advocate lady of actionlyme.org,has postulated that Osp A,the antigen shed in Lyme disease causes immune-suppression and wonky B cells-Hilary
