Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with Long Covid, post-treatment Lyme disease syndrome, or ME/CFS who feel clearly less well than before they got ill. Each person must have only one of the three conditions.
- Age
- 18 years or older
- Sex
- All genders can join.
- Disease stage
- Long Covid: confirmed or suspected COVID-19 at least 3 months before contact with the study team, plus a formal Long Covid diagnosis from a physician. Post-treatment Lyme disease syndrome: meets the Columbia Clinical Trial Network diagnostic criteria (Group 1 or Group 2). ME/CFS: formal diagnosis from a physician before 2020, and still meets the 2011 International Criteria at screening.
- Biomarker or test result
- Post-treatment Lyme disease syndrome: Group 1 requires a Class 1 lab test confirming Lyme infection. Group 2 includes some people with a positive Class 1 lab test or a highly suggestive IgG Western blot (4 of 10 bands). Baseline EQ-VAS (a health rating score) of 70 or less, and 80 or more before the infection.
Main reasons for not taking part
- Current use of blood thinners (antiplatelet or anticoagulant)
- An autoimmune condition such as Chronic EBV, Multiple Sclerosis or Hashimoto's Disease
- Pregnancy or breastfeeding
- Known allergy to earthworms
- Past bleeding or clotting disorder, or surgery planned during or right after the study
The registry criteria, word for word
Show all 20 criteriaShow less
Who can take part
- Any gender
- Aged 18+
- Baseline EQ-VAS ≤70; EQ-VAS before the index infection ≥80 (this information is collected as part of the baseline survey)
- Diagnosed with only one of the following conditions:
- Long Covid
- Documented clinical history of confirmed or suspected acute COVID-19 infection a minimum of 3 months prior to contact with the study team
- Formal diagnosis of Long Covid from a physician
- Post-treatment Lyme disease syndrome
- Diagnosis will be based on participants meeting either Group 1 or Group 2 criteria of the Columbia Clinical Trial Network PTLDS diagnostic criteria:; Group 1. Well-defined Lyme disease meeting CDC Surveillance Definition Erythema Migrans History of possible exposure to a high incidence county or state (or an adjacent area) Erythema migrans rash; EM 1: EM rash diagnosed by HCP previously (either in person or telemedicine); EM 1A: MOA self-report \& medical record documentation of rash > 5 cm; EM 1B: MOA: self-report and medical record documentation of EM rash but not size; EM 1C: MOA: self-report \& rash misdiagnosed in medical record as cellulitis/spider bite; EM 1D: MOA: self-report and either: photo of EM or Class 1 lab test confirmation within 4 weeks of illness onset OR; Disseminated "objective" manifestation with lab test confirmation of Bb infection; Clinical history includes at least one of the following symptoms/signs, which are not better accounted for by another cause (MOA: medical records and/or self-report); Neurologic: Lymphocytic Meningitis ; Encephalitis; Encephalomyelitis Cranial Neuritis (especially facial palsy); Radiculoneuropathy; Other Neurologic Signs (with objective measures) : Encephalopathy, Polyneuropathy; Carditis: 2nd or 3rd degree AV block; Myocarditis; Pericarditis; Lyme arthritis: Recurrent joint swelling in one or more joints; Dermatologic: Disseminated EM ("satellite") or Acrodermatitis atrophicans AND; Lab test Confirmation (requires at least one of the Class 1 lab tests) (MOA: self-report \& documentation); Group 2. Probable; 2A. Chronic Multisystem Symptoms attributed to Lyme disease (insufficient to meet Group 1) and not better explained by another diagnosis and patient has evidence of positive lab results on a Class 1 lab test (or 4 of 10 bands for IgG Western blot (WB)) (MOA: self-report with lab documentation Class 1 lab test confirmation (excluding IgM WB) Highly suggestive IgG WB (4 of 10 bands) OR; 2B. EM rash by history after exposure to a Lyme-endemic area but not previously diagnosed by a HCP and no photo or Class 1 lab test confirmation is available (MOA: self-report) OR; 2C. Viral like illness (not better explained by other cause) with indeterminate or + enzyme immunoassay (EIA) with positive IgM WB or positive Class 1 lab test (within 4 weeks of illness onset after known exposure to a Lyme high-incidence area for standard two-tiered (STT) IgM) (MOA: medical records, lab test and self-report) (MOA: lab test and self-report) OR; 2D. Viral like illness (not better explained by other cause) with indeterminate or positive EIA with positive IgM WB or positive Class 1 lab test (within 6 months of illness onset after known exposure to a Lyme high-incidence area for standard two-tiered (STT) IgM)
- (MOA: medical records, lab test and self-report)
- (MOA: lab test and self-report)
- ME/CFS
- Formal diagnosis of ME/CFS prior to 2020 from a physician
- Actively symptomatic such that the 2011 International Criteria for ME/CFS is met at time of screening
Who cannot take part
- Has a scheduled surgery during, or immediately after, the study period
- Diagnosis of an autoimmune condition such as Chronic EBV, Multiple Sclerosis, Hashimoto's Disease, etc. which would impact the immunological profiling analysis

- Past medical history of a bleeding or clotting disorder
- Current use of antiplatelet or anticoagulation regimen
- Pregnancy or lactation
