Work Summary

Stefano Guerra's work includes an epidemiologic study, which used a household-based approach to assess prevalence and longitudinal changes in respiratory health. Other biomarker projects include a study on molecular biomarkers of asthma and COPD from the European Community Respiratory Health Survey.

Research Interest

Stefano Guerra, MD, PhD, is a professor of Medicine, the Director of the Population Science Unit at the Asthma and Airway Disease Research Center, and a leading expert in the natural history and biomarkers of obstructive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD). As principal investigator, he is engaged in the leadership and coordination of multiple studies that use bio-specimens and phenotypic information from independent epidemiological cohorts to characterize the natural history, profile the risk factors, and identify novel biomarkers of lung diseases.

Systematic Review on the Definition of Allergic Diseases in Children: The MeDALL Study. International archives of allergy and immunology, 168(2), 110-21.

During the last decades, a large number of phenotypes and disease classifications of allergic diseases have been proposed. Despite the heterogeneity across studies, no systematic review has been conducted on phenotype classification and the criteria that define allergic diseases. We aimed to identify clinically expressed, population-based phenotypes of allergic diseases and their interrelationships, to explore disease heterogeneity and to evaluate the measurements employed in disease diagnosis.

Respirology (Carlton, Vic.), 21(3), 476-82.

Exercise capacity decline is a predictor of mortality in patients with chronic obstructive pulmonary disease (COPD). Static pulmonary hyperinflation is a key determinant of exercise performance, but its effect on the longitudinal decline in exercise capacity remains unknown. We aimed to study the relationship between the inspiratory capacity-to-total lung capacity (IC/TLC) ratio and exercise capacity decline in COPD.

A number of genetic variants have been associated with allergic sensitization, but whether these are allergen specific or increase susceptibility to poly-sensitization is unknown. Using data from the large multicentre population-based European Community Respiratory Health Survey, we assessed the association between 10 loci and specific IgE and skin prick tests to individual allergens and poly-sensitization. We found that the 10 loci associate with sensitization to different allergens in a nonspecific manner and that one in particular, C11orf30-rs2155219, doubles the risk of poly-sensitization (specific IgE/4 allergens: OR = 1.81, 95% CI 0.80-4.24; skin prick test/4+ allergens: OR = 2.27, 95% CI 1.34-3.95). The association of rs2155219 with higher levels of expression of C11orf30, which may be involved in transcription repression of interferon-stimulated genes, and its association with sensitization to multiple allergens suggest that this locus is highly relevant for atopy.
