Complement Activation Markers in Patients with Long COVID

A clinical dataset contains measurements of complement activation markers C3bc, C3bBbP, and TCC from 128 subjects. The data was collected by researcher Madlene Holmqvist and published on figshare in 2026. It compares 48 patients with Post-Acute Sequelae of SARS-CoV-2 infection to 80 recovered controls.

Use Cases

• Compare complement activation levels between PASC patients and recovered controls based on the described cohort.
• Analyze potential links between initial COVID-19 severity and long-term complement dysregulation based on the patient stratification.
• Investigate biomarker trends over a post-infection period of up to 33 months as mentioned in the description.

Strengths

• Includes measurements for three specific complement markers: C3bc, C3bBbP, and TCC.
• Compares a defined cohort of 48 PASC patients against 80 control subjects.
• Data covers a post-infection observation period of up to 33 months.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
