Second cohort following patients entering a multidisciplinary care pathway for post-COVID syndromes (SyPoCo2)

Second Prospective Cohort of Patients Entering the Multidisciplinary Care Pathway for Post-Covid Syndromes - SyPoCo2 Cohort

Observational Hospices Civils de Lyon · NCT07356570

This project will test whether linking long COVID patients' symptoms with blood immune and molecular markers can find biomarkers and possible treatment targets.

What this trial studies

SyPoCo2 is an observational cohort enrolling adults referred to specialized post-COVID care pathways in the Hospices Civils de Lyon system. Participants provide blood samples and detailed clinical information so researchers can correlate symptom patterns with immunological and molecular data. The goal is to identify prognostic biomarkers and signals that could point to therapeutic targets. Data will be analyzed to define clinical profiles and molecular signatures associated with persistent post-COVID symptoms.

Who should consider this trial

Good fit: Adults (≥18) with documented SARS-CoV-2 infection who have persistent or complex post-COVID symptoms and are referred to the EPSILON pathway or the post-COVID rehabilitation unit, non-institutionalized, and expected to survive more than six months are ideal candidates.

Not a fit: People without confirmed SARS-CoV-2 infection, with uncontrolled comorbidities, who are pregnant or breastfeeding, under legal protection or deprived of liberty, not covered by the French national health insurance system, or institutionalized are not eligible and would not benefit from participation.

Why it matters

Potential benefit: If successful, the work could produce blood-based markers that help predict who will have prolonged symptoms and suggest targets for future treatments.

How similar studies have performed: Previous observational cohorts have identified immune and molecular signals linked to long COVID but no universally validated prognostic biomarkers or approved targeted therapies have yet been established.
