Inflammatory Responses in Solitary and Multiple Erythema Migrans


The investigators will evaluate differences in host immune responses (levels of cytokines and chemokines, representative of innate, Th1, and Th17 immune responses) in acute sera from adult patients with solitary or multiple erythema migrans.

Full Title of Study: “Inflammatory Responses in Borrelia Afzelii Culture Positive Patients With Early Disseminated or Early Localized Lyme Borreliosis”

Clinical Trial Outcome Measures

Primary Measures

  • inflammatory proteins in erythema migrans patients
    • Time Frame: at enrollment
    • The inflammatory immune profiles will be assessed using Luminex to measure the expression of cytokines and chemokines representative of innate and adaptive TH1, TH2, TH17, and B cell responses in serum of patients at enrollment (during active infection).
