Outcome Measures
Primary Outcomes (1)
Sample Data Analysis
The results will be used to calculate performance, including sensitivity and specificity of the tests under evaluation. The utility of these tests at different time points post initial presentation will be evaluated.
Tests at different time points post inital presentation will be evaluated through study completion, an average of 1 year.
Study Arms (3)
1a:Lyme patients- Erythema Migrans(EM)rash present
Patients with newly diagnosed Lyme disease based on the presence of a physician-documented EM rash. PCR, serology and Tcell based assay.
1b:Lyme patients no typical EM
Patients documented symptoms of early Lyme disease, without a typical EM rash present, and the physician's intention to treat for Lyme disease. PCR, serology and Tcell based assay
Cohort 2: healthy controls
Patients drawn from Lyme disease non-endemic areas and subjects with known exposure to Lyme disease will be excluded. PCR, serology and Tcell based assay.
Interventions
Whole blood specimens will be tested for the presence of Borrelia DNA by PCR in a two-step test (Imugen). In Cohort 1a and 1b. The first step tests for the presence of any Borrelia DNA. The second step is employed on positive samples and tests for the presence of either B. burgdorferi DNA or B. miyamotoi DNA. Positivity by PCR has a short but early window in the infection cycle for Borrelia burgdorferi and results may enable this window period and diagnosis rates to be better defined. In addition co-infection PCR analysis will be performed for the presence of Babesia, Anaplasma or Ehrlichia DNA (Imugen).
1. The Imugen Lyme Antibody Analysis which includes immunoglobulin M (IgM),immunoglobulin G (IgG), and immunoglobulin A (IgA) antibody capture immunoassay and IgG and IgM based Western blots. In Cohort 1a and 1b. 2. The Immunetics C6 Lyme ELISA assay. 3. A 2-tier Lyme test performed and interpreted according to Centers for Disease Control (CDC) Guidelines 4. A Rickettsia antibody test will be used to identify Spotted Fever and Typhus fever groups infections. Lyme test methodologies generally indicate a need to run a combination of tests in order to overcome limitations in either sensitivity or specificity of the various individual tests. Performance of all these tests on the same set of samples should enable both individual and combinatorial performance values to be calculated and compared.
A research based ELISpot assay will be performed on peripheral blood mononuclear cells (PBMC) extracted from whole blood samples to test for presence of T cells activated against Borrelia antigens. Unlike serology based methods, this signal may not persist over extended periods of time in the absence of Borrelia antigens. The diagnostic window may be different for a test measuring adaptive immune response (i.e. T cells) and thus such test may identify patients with undetectable antibody response and may aid sensitivity of diagnosis.
Eligibility Criteria
500 subjects aged 5 years or older.
You may qualify if:
- Cohort 1a (typical EM and intention to treat):
- Documented new onset Lyme disease EM rash (single or multiple) with photographic evidence provided to Oxford Immunotec.
- Patient must be able to provide blood sample at the initial visit (prior to treatment initiation) and subsequent samples according to the schedule.
- Patients 5 years of age or older, with a minimum weight of 40 pounds.
- Patient able to read English and to give consent to study participation.
- If patient is younger than 18 years of age a legally authorized representative must provide consent.
- Cohort 1b (no typical EM; Lyme disease symptoms; intention to treat):
- Patients with suspected Lyme disease, based on physician's examination, where the physician has the intention to treat for Lyme disease (i.e. patients who following initial examination were prescribed treatment for Lyme disease).
- Documented new onset of Lyme disease symptoms without a typical EM rash or with no rash. If a rash is present, photographic evidence must be provided.
- Patient must be able to provide blood sample at the initial visit (prior to treatment initiation) and subsequent samples according to the schedule.
- Patients 5 years of age or older, with a minimum weight of 40 pounds.
- Patient able to read English and to give consent to study participation.
- If patient is younger than 18 years of age a legally authorized representative must provide consent.
- Cohort 2 (Healthy subjects):
- Subjects 5 years of age or older, with a minimum weight of 40 pounds.
