Chronic mucocutaneous candidiasis

Chronic mucocutaneous candidiasis is a genetically heterogeneous group of disorders, which are characterised by chronic or recurrent non-invasive skin, nail and mucous membrane infections caused by Candida. The increased susceptibility to Candida infections is due to a Th17-cell mediated immune detect with different gene mutations in the background. The isolated form of the disorder, referred to as chronic mucocutaneous candidiasis, presents primarily or only with mucocutaneous candidiasis. In contrast, the syndromic form of the disorder is characterised, besides the non-invasive Candida infections, by autoimmune disorders, which most commonly affect the endocrine system. Genetic tests are important in confirming the diagnosis, which in affected families would provide the opportunity for prenatal genetic testing. The authors present the main types of chronic mucocutaneous candidiasis, exploring the clinical aspects, diagnostic methods, and available therapies. Furthermore, the authors conclude the molecular genetic background and the currently known pathomechanism of the disorder.
