A Prospective Study to Evaluate the Role of T-Cell Dysfunction in Patients Who Present Symptoms Associated With Long COVID, Lyme Disease and Myalic Encephalomyelitis / Chronic Fatigue Syndrome Using the Vira Immune Fluorospot T Cell Assay
United Kingdom160 participantsStarted 2024-12-10
Plain-language summary
This is a longitudinal observational study recruiting individuals that have attended three clinical sites with symptoms associated with a diagnosis of long COVID, PTLDS or ME/CFS. The study will be a multi-centre study, with up to 160 male and female participants enrolled. Participants that experience symptoms considered to be associated with a diagnosis of long COVID, PTLDS or ME/CFS will consent to the study, and attend for two study visits (at study entry and 6 months) to complete a questionnaire related to their symptoms, and to have a blood sample taken. Blood samples will be taken either at the clinical site or at the participant's home if they are unable to attend due to the severity of their illness. . Participants will be allocated to one of the following groups:
Group 1: Long COVID Group 2: ME/CFS Group 3: PTLDS Group 4: Healthy Control

Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Performance of the ViraxImmune FluoroSpot T cell assay (PPA / NPA - predicted outcome)
. Taking immunosuppressive medication (including corticosteroids), or receiving chemotherapy, cytokine or anti-cytokine therapy, or antithrombotic medication (evaluation through questionnaire).
. Significant and/or acute illness within 5 days prior to admission that may impact safety assessments, in the opinion of the Investigator.
. Participants who are, in the opinion of the Investigator, not suitable for enrolment for another reason. For example, participants with: cognitive impairment or severe mental health conditions that might affect their ability to provide informed consent or follow study procedures; non-adherence risk where participants are unlikely to follow study protocols; participants with other chronic inflammatory conditions not under investigation e.g. inflammatory bowel disease, COPD that may have immune profiles that differ from the study's intended populationI
