Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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

You may not qualify if…

• Current use of antiplatelet or anticoagulation regimen
• Diagnosis of an autoimmune condition such as Chronic EBV, Multiple Sclerosis, Hashimoto's Disease, etc. which would impact the immunological profiling analysis.
• Pregnancy or lactation
• Known allergy to earthworms (Lumbrokinase is a supplement that is derived from earthworms)
• Past medical history of a bleeding or clotting disorder
• Has a scheduled surgery during, or immediately after, the study period

Where it is running

• The Cohen Center for Recovery from Complex Chronic Illnesses (CoRE) — New York, New York, United States (enrolling)
