Research interests

Zsolt Szépfalusi is M.D. and trained pediatrician with specialty in pediatric allergology and pulmonology. Early scientific activities focused on IgE-mediated allergies and in particular on the mode of materno-fetal interaction with allergic sensitization (1993-1996). On an ex-vivo placenta model experimental data support the idea of an early materno-fetal allergen-cross talk (1998-2005), that seems to be a Th1-driven response. (2006-2012). Clinical studies have been started to elucidate the early and preventive effect of allergen-specific immunotherapy in young children (2005-ongoing). The first placebo-controlled, sensitization-preventive sublingual immunotherapy trial (2008-2012) showed immuno-modulatory effects in actively treated (2014). A confirmatory placebo-controlled trial is under investigation (2018-2022). In cross-sectional, prospective and immunological studies the particular Th2-driving capacity of tacrolimus in organ transplantation could be shown (2006-2014). New biomarkers are needed for food allergy diagnosis. The role of the high-affinity FcERI is studied in vitro and in various types of IgE- and non-IgE-mediated allergies (2007-2021) in order to delineate possible biomarkers. Covid-19 infection also affects children. In a recent large cross-sectional study on 2069 schoolchildren in Vienna a PCR-prevalence of 0.1% (n=2) and a seroprevalence of 1.3% (n=26) was observed.
