Brief Summary

There are more than 300,000 new cases of Lyme disease every year in the US. Lyme disease is a dangerous bacterial infection transmitted by tick bites and it becomes increasingly severe as the infection progresses. Definitive diagnosis is based on serum-based tests that have fundamental limitations: 1) current tests cannot detect early infections so patients do not receive antibiotic therapy until the infection has progressed, and 2) there is no way to measure if antibiotic therapy has been successful. MicroB-plex will address these two unmet clinical needs by introducing a novel, blood-based diagnostic method that will enable clinicians to diagnose infections earlier and to monitor the success of their interventions.

Outcome Measures

Primary Outcomes (2)

  • Percentage of EM positive patients who become MicroB-plex Lyme test positive prior to seroconversion

    MicroB-plex Lyme Test, that measures anti-Lyme antibodies in MENSA, becomes positive prior to conventional Lyme immunoassays that measure antibodies in serum, resulting in earlier diagnosis

    Within 14 days of enrollment

  • Percentage of treated EM positive patients who become MicroB-plex Lyme test negative prior to their decline in serum

    MicroB-plex Lyme Test, that measures anti-Lyme antibodies in MENSA, becomes negative with successful treatment, prior to a decline in serum antibody level in conventional immunoassays, providing an earlier measure of effective therapy

    Up to one year from enrollment

Secondary Outcomes (1)

  • Percentage of treated EM positive patients who remain MicroB-plex Lyme test positive following treatment

    Up to one year from enrollment

Study Arms (2)

Lyme Infected

Subjects presenting with suspected Lyme Disease

Diagnostic Test: MicroB-plex Lyme Immunoassay

Controls

Subjects with no known Lyme Disease, past or present

Diagnostic Test: MicroB-plex Lyme Immunoassay

Interventions

Subject's blood and clinical data are collected to develop a diagnostic immunoassay

ControlsLyme Infected

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult humans with a strong clinical suspicion of acute Lyme disease, with symptoms seven days or less. Subjects will be recruited from medical centers residing in Maryland.

You may qualify if:

  • Human adults at least 21 years of age and no more than 80 years of age at the time of screening.
  • Have the ability to understand the requirements of the study, provide written informed consent (including consent for the use and disclosure of research-related health information), and comply with the study protocol procedures (including required study visits).
  • High clinical suspicion of acute Lyme disease, with symptoms seven days or less.
  • Must have erythema migrans rash and physician diagnosis of early Lyme disease.
  • Brief history and physical exam will be obtained during the study visit.
  • Be willing to return to our clinic for up to nine visits and blood draws over a one-year period.
  • People who do not have Lyme disease, but want to participate as healthy controls (one time visit)

You may not qualify if:

  • Have poor venous access.
  • Have received any immunosuppressive therapy including biologics or recent course of steroids, or recent chemotherapy.
  • Anti-TNF therapy (eg, adalimumab, etanercept, infliximab).
  • Intravenous (IV) cyclophosphamide
  • Interleukin-1 receptor antagonist (anakinra).
  • Intravenous immunoglobulin (IVIG).
  • High dose prednisone or equivalent (\> 100 mg/day).
  • Plasmapheresis.
  • Any new immunosuppressive/immunomodulatory agent
  • Any steroid injection (eg, intramuscular, intraarticular, or intravenous).
  • On treatment for Lyme disease greater than seven days
  • Recent chemotherapy
  • History of solid organ transplant
  • History of autoimmune disorders (SLE, Rheumatoid arthritis, Scleroderma, etc.)
  • History of inflammatory muscle disease (polymyositis, dermatomyositis, etc.)
  • +5 more criteria
