Chronic mucocutaneous candidiasis, from bench to bedside.

Area of Science:

• Immunology
• Dermatology
• Genetics

Background:

• Chronic mucocutaneous candidiasis (CMC) is a group of rare inherited syndromes.
• Characterized by persistent Candida yeast infections of skin and mucous membranes.
• Underlying immune dysfunction involves defects in dendritic cell (DC)/T cell responses, impairing Th17 and Th1 immunity.

Purpose of the Study:

• To summarize current knowledge on the incidence, prognosis, and clinical complications of CMC.
• To highlight the immunological underpinnings of CMC, focusing on DC/T cell defects.
• To emphasize the need for effective therapeutic strategies in managing CMC.

Main Methods:

• Review of existing literature on CMC.
• Analysis of immunological data related to Th17 and Th1 responses in CMC patients.
• Clinical case study review focusing on complications and treatment outcomes.

Main Results:

• CMC is associated with significant complications, including debilitating hand lesions (Candida granuloma) and esophageal strictures.
• Impaired Th17 and Th1 immune responses are key features of the DC/T cell defect in CMC.
• Chronic infections may increase the risk of developing squamous cell carcinoma.
• Rapid development of antifungal drug resistance necessitates adaptable treatment approaches.

Conclusions:

• CMC presents a complex clinical challenge requiring a multidisciplinary approach.
• Understanding the immune defect is crucial for developing targeted therapies.
• Prognosis is influenced by the severity of complications and the ability to manage infections and drug resistance effectively.
