Abstract:
Candida spp. are colonizing fungi of human skin and mucosae of the gastrointestinal and genitourinary tract, present in 30-50% of healthy individuals in a population at any given moment. The host defense mechanisms prevent this commensal fungus from invading and causing disease. Loss of skin or mucosal barrier function, microbiome imbalances, or defects of immune defense mechanisms can lead to an increased susceptibility to severe mucocutaneous or invasive candidiasis. A comprehensive understanding of the immune defense against Candida is essential for developing adjunctive immunotherapy. The important role of underlying genetic susceptibility to Candida infections has become apparent over the years. In most patients, the cause of increased susceptibility to fungal infections is complex, based on a combination of immune regulation gene polymorphisms together with other non-genetic predisposing factors. Identification of patients with an underlying genetic predisposition could help determine which patients could benefit from prophylactic antifungal treatment or adjunctive immunotherapy. This review will provide an overview of patient susceptibility to mucocutaneous and invasive candidiasis and the potential for adjunctive immunotherapy.
Insights
Candida fungi commonly colonize healthy individuals. Genetic factors and immune defects increase susceptibility to invasive candidiasis, necessitating research into adjunctive immunotherapies.
Area of Science:
- Immunology
- Medical Mycology
- Genetics
Background:
- Candida species are commensal fungi found on human skin and mucosae.
- Host immune defenses normally prevent Candida invasion.
- Impaired immunity, barrier dysfunction, or microbiome imbalance can lead to candidiasis.
Purpose of the Study:
- To review patient susceptibility to mucocutaneous and invasive candidiasis.
- To explore the potential for adjunctive immunotherapy in managing Candida infections.
- To highlight the role of genetic predisposition in Candida susceptibility.
Main Methods:
- This is a review article.
- It synthesizes existing literature on Candida infections and host immunity.
- It discusses genetic and non-genetic factors influencing susceptibility.
Main Results:
- Susceptibility to candidiasis is often multifactorial, involving genetic polymorphisms and environmental factors.
- Understanding immune responses is crucial for developing new treatments.
- Identifying genetic predispositions may guide prophylactic strategies.
Conclusions:
- Adjunctive immunotherapy holds promise for treating invasive candidiasis.
- Further research into host-pathogen interactions and genetic susceptibility is warranted.
- Personalized treatment approaches may benefit high-risk patients.
