Anti-lysoganglioside and other anti-neuronal autoantibodies in post-treatment Lyme Disease and Erythema Migrans after repeat infection

Anti-lysoganglioside and other anti-neuronal autoantibodies in post-treatment Lyme Disease and Erythema Migrans after repeat infection

Brian A.Fallon, BarbaraStrobino, SeanReim, JulieStoner, Madeleine W.Cunningham Brain, Behavior, & Immunity – Health, Volume 2, February 2020, 100015. https://doi.org/10.1016/j.bbih.2019.100015

This study examines molecular mimicry targeting neural tissue after Borrelia burgdorferi (Bb) infection. Patients with Lyme disease have a greater frequency of specific anti-neuronal autoantibodies and functional neuronal activation compared to community controls without a history of Lyme disease.

“Highlights

  • The EM ​+ ​prior LD group had significantly elevated anti-neuronal antibodies.
  • The EM ​+ ​prior LD group had significantly elevated CaM Kinase activation.
  • Anti-Lysoganglioside Antibodies are significantly elevated in the PTLS group.
  • Prior infection may lead to immune priming and increased autoantibodies.”
A minority of children diagnosed with Lyme disease recall a preceding tick bite
Nigrovic LE, Neville DN, Balamuth F, Bennett JE, Levas MN, Garro AC; for Pedi Lyme Net. A minority of children diagnosed with Lyme disease recall a preceding tick bite. Ticks Tick Borne Dis. 2019 Apr;10(3):694-696. doi: 10.1016/j.ttbdis.2019.02.015. Epub 2019 Feb 26. PMID: 30853264.

Out of 1770 children evaluated in the emergency department for Lyme disease, 362 (20.5%) were diagnosed with the condition. Among those with a documented tick bite history, only a small percentage (18.5%, 95% confidence interval 14.6-23.0%) of Lyme disease cases were associated with a recognized tick bite. Therefore, the absence of a tick bite history does not reliably rule out Lyme disease.

C-Reactive Protein Response in Patients With Post-Treatment Lyme Disease Symptoms Versus Those With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

The data suggest the presence of different inflammatory mechanisms in ME/CFS compared to PTLDS. This difference may stem from the potentially more diverse causes of ME/CFS symptoms compared to PTLDS. The lack of a significantly elevated CRP response in ME/CFS, despite indications of activation in other inflammatory pathways, requires further investigation.
