[Dermatophytic disease. Recent Algerian observations]

Area of Science:

• Dermatology
• Immunology
• Infectious Diseases

Background:

• Dermatophytosis, a fungal infection of the skin, hair, and nails, is typically superficial.
• Understanding the immunologic basis of severe fungal infections is crucial for effective treatment.

Observation:

• Five cases of severe dermatophytic disease in Algiers exhibited distinct clinical features.
• Key observations included a familial predisposition to the infection.
• Patients presented with compromised cell-mediated immunity and elevated immunoglobulin E (IgE) levels, while humoral immunity appeared intact.

Findings:

• The study highlights a severe form of dermatophytosis linked to genetic factors and specific immune deficiencies.
• One patient developed a cerebral abscess, a rare and life-threatening complication.
• Another patient succumbed to the infection despite receiving griseofulvin therapy, indicating treatment resistance.

Implications:

• These findings suggest a need for further research into the immunogenetics of dermatophytosis.
• Early identification of at-risk individuals with familial predisposition and immune deficits is warranted.
• The severity observed underscores the importance of developing novel therapeutic strategies for refractory cases.
