Abstract We tested a novel way of visualizing relationships between serum biomarkers and clinical outcomes using heat-map colors in 253 COPD and 92 non-COPD subjects over 3 years. Using high sensitivity ELISA testing, we measured IL-6, IL-8, IL-16, TNF- as indicators of inflammation, VEGF, MMP-9 as indicators of injury and repair and, PARC, MCP-1 as novel markers. We explored differences in clinical descriptors between the highest and lowest quartiles of biomarkers‘ levels. We assessed the importance of differences in clinical variables using known MICD and expressed using heatmap colors. Differences associated with good outcomes are shown in green, poor outcomes in red and no differences in yellow. COPD patients had a specific biomarker profile where upper quartiles of inflammatory cytokines and injury&repair cytokines were associated with poor and good outcomes, resp. This pattern replicated in all biomarkers, but IL-8 and PARC at subsequent annual visits. No specific profile was observed in non-COPD subjects. We describe a new method to express COPD specific serum biomarkers profile that replicates during 3 year follow-up. The profile is not seen in non-COPD controls. The Heatmap-Clinical profile pattern is associated with several clinical expressions of COPD. Data analysis support provided by GlaxoSmithKline R&D.
