Bartonella henselae, Babesia odocoilei and Babesia divergens-like MO-1 infection in the brain of a child with seizures, mycotoxin exposure and suspected Rasmussen’s encephalitis
Breitschwerdt EB, Maggi RG, Robveille C, Kingston E. Bartonella henselae, Babesia odocoilei and Babesia divergens-like MO-1 infection in the brain of a child with seizures, mycotoxin exposure and suspected Rasmussen’s encephalitis. J Cent Nerv Syst Dis. 2025 Mar 12;17:11795735251322456. doi: 10.1177/11795735251322456. PMID: 40083671; PMCID: PMC11905044.
  • Despite cat and suspected tick exposure, Bartonella henselae and Borrelia burgdorferi serology remained negative.
  • Neurodiagnostic testing partially supported Rasmussen’s encephalitis; brain biopsy showed astrogliosis.
  • Bartonella henselae DNA was detected in brain tissue cultures.
  • Babesia odocoilei and Babesia divergens-like MO-1 were confirmed in blood and brain tissue from 2022–2023.
  • Infections, compounded by mycotoxin exposure, created a complex clinical case.

Obsessive Compulsive Disorder associated with Autoimmunity in Youth: Clinical Course before and after Rituximab+/- Adjunctive Immunomodulation. Dev Neurosci. 2025 Mar 10:1-26. doi: 10.1159/000544993.

  • Case review (n=23) from Stanford on their use of rituximab for presumed-neuroimmune and severe OCD in youth
  • Some (47.8%) experienced transient increases in psychiatric or joint pain symptoms before signs of improvement. The time frame for signs of improvement was 3-4 months. 
  • 70% achieved full or partial recovery at 1-5 years.
  • Receiving adjunct immunomodulation was associated with a higher likelihood of achieving full or partial recovery compared with those without adjunct immunomodulation
