Abstract
Oral Lichen Planus (OLP) is an oral inflammatory condition, mediated by host
immune system reaction, presenting basal membrane damages with inflammatory
lesions in the mouth and/or skin. In this study, the role of functional
polymorphisms in the MBL2 gene, encoding for Mannose-Binding Protein C (MBP-C),
a member of the innate immune response and an acute-phase protein able to
activate the complement cascade, was investigated to assess a possible
association with OLP susceptibility in Italian patients. Two variations at the
promoter region (called H/L and X/Y) and three at the first exon (at codon 52,
54, and 57) of the MBL2 gene were analyzed in 69 OLP patients and 244 healthy
controls from northeastern Italy. Considering the polymorphisms singularly, the
MBL2 X allele and C/T genotype of the D allele (correlated with low MBP-C
expression) were associated with susceptibility to develop OLP. Moreover, when
taking into account MBL2 combined genotypes, more OLP patients were deficient
MBP-C producers than not deficient, who were more represented among healthy
controls. MBL2 combined genotypes, responsible for deficient MBP-C production,
are associated with an increased risk of developing OLP.

Abstract
OBJECTIVES Candida albicans is the most common fungal pathogen in humans, but other Candida species cause candidosis. Candida species display significant differences in their susceptibility to antimycotic drugs. Patients with symptomatic or erythematous oral lichen planus (OLP) commonly have Candida infection requiring correct identification of Candida species in order to initiate adequate antimycotic therapy. Therefore, conventional cytosmear and culture tests were compared with genetic diagnostics on oral rinse followed by agar culture and material collected by cytobrush from OLP patient mucosal lesion. METHODS The genetic approach was validated on a reference panel of 60 well-defined unrelated fungal species. The study included 37 OLP patients. Oral candidosis (OC) was established based on clinical signs of OC and/or oral mucosal symptoms and at least one hypha in lesional cytosmear. Antimycotic treatment was initiated after OC diagnosis, and symptomatic treatment was initiated in no-candidosis situations. RESULTS The composition of Candida species in oral rinse/culture test was different from that of lesional cytobrush sampling as more non-albicans species were detected by the latter. Unexpectedly, Candida dubliniensis was found to be overrepresented among patients with a history of antimycotic treatment indicating unintentional iatrogen selection. Of the 22 OLP patients receiving treatment, 27% of these should have been offered alternative therapy based on the improved diagnostic approach. CONCLUSION This study highlights the importance of lesional sampling in OLP patients with suspected OC. CLINICAL RELEVANCE Correct fungal identification is critical in order to initiate adequate antimycotic therapy, thus minimizing iatrogen selection of non-albicans species.
