Figure 4From: TH2-like Chemokine Patterns Correlate with Disease Severity in Patients with Recurrent Respiratory PapillomatosisPlasma CCL18 levels decrease in concert with improved clinical status in patients treated with celecoxib, a COX-2 inhibitor. Three patients (A,B,C) in the pilot clinical trial had CCL18 levels (solid line) measured by a single-plex ELISA in plasma samples collected at varying times during the study. Clinical improvement, denoted by reduction in severity score (gray bars), correlated with decreasing CCL18 concentrations.Back to article page
