Mould specific IgG antibodies connected with sinusitis in teachers of mould damaged school: a two-year follow-up study.

Abstract

In a two-year follow-up the total concentration of the IgG antibodies for Tr. toseum was lower at the end than at the beginning of the follow-up and this remained significant for the group of teachers with sinusitis. The decrease in mould specific IgG to Cl. cladosporioides, Geotrichum candidum, Ph. bubakii and Rhizopus nigricans was associated with bronchitis. According to our knowledge, this is the first study in which the association between elevated mould specific IgG antibodies and sinusitis was found in the school environment.
