Changes in complement activation fragments over time and after immunosuppression. We measured C4a, Ba, and sC5b-9 in plasma collected in 83 patients with nephrotic syndrome from the Nephrotic Syndrome Study Network Consortium cohort at baseline and during follow-up visits. No significant changes in any of the complement fragments were seen over time. Graphs show the medians for each time point; bars indicate interquartile ranges.
