Curriculum vitae

Renaud LOUIS was born in Liege (Luik) in 1963. He was graduated as Doctor in Medicine from University of Liege in 1987 and as Specialist in Respiratory Medicine in 1993 from the same University. Then he trained as Research Fellow at Southampton University (UK) from 1994 to 1996 in the department of Prof Steve Holgate. He obtained his Aggregation of superior teaching at the University of Liege in 1998 with a research thesis entitled "Contribution to study of bronchial hyperresponsiveness and airways inflammation in atopic asthmatic" and a public lesson dedicated to "COPD". He got a permanent position as member of the Pneumology Staff at CHU sart-Tilman in 1998. He was appointed by University of Liege as Associate Professor in Respiratory Medicine in 2000. In 2003 he was invited by Prof Miel Wouters, Head of the Respiratory Medicine Department at Maastricht University, to join the team for one year on a part-time basis as visiting Professor. He was appointed full Professor of Respiratory Medicine and Head of the department of Respiratory Disease in 2004. He also was president of the Belgian Thoracic Society from 2012 to 2014 and served as European respiratory Official from 1998- 2003 and as national delegate from 2005-2008. His current research interest is focused on airways inflammation in asthma and COPD and is member of the GINA (Global Initiative for Asthma) assembly.

Body: Oxidative stress generates volatile organic compounds (VOCs) excreted in exhaled air. Induced sputum is currently the best available noninvasive assessment of bronchial inflammation in asthma and we currently lack of markers for airway neutrophilia.
The purpose of the study was to examine whether specific VOCs are associated with eosinophilic and neutrophilic inflammation for noninvasive monitoring of asthma inflammatory phenotypes.

This is a prospective study on 276 asthmatics recruited from the asthma clinic of CHU Liege between 2010 and 2014. Patient underwent VOCs measurement by GCMS analysis, FENO, spirometry with bronchodilation, sputum induction, blood sample and validated asthma control and quality of life questionnaires. One week later, a methacholine challenge was performed. We used conditional inference forests (CIFs) to rank features based on the ability of components to predict phenotypes.The chemical nature of the compounds was found in NIST Library.


3328 VOCs were detected in the exhaled air from eosinophilic (eos≥3%, n=122), neutrophilic (neutro≥76%, n=50) and paucigranulocytic (n=90) asthmatics. We filtered out components that were detected in <30 samples. When comparing VOCs from paucigranuloctytic to eosinophilic asthma, 3 components (P337, P903, P923) were good discriminators. We found that P2622 and P2853 were VOCs able to distinguish between neutrophilic and paucigranulocytic while peak 253 and 1913 were best for eosinophilic versus neutrophilic discrimination.
Our study is the first attempt to characterize VOCs according to sputum inflammatory phenotypes in a large asthmatic population. Our results show that VOCs analysis may be a valuable method to phenotype asthmatics.
