Abstract:
The importance of mycotic infections of the skin and its adnexa has a rising trend. The causal agents are not only dermatophytes and candidae but to an increasing extent opportune fungal microorganisms. Most frequently these diseases develop during intense immunosuppressive treatment, e.g. in oncological, oncohaematological diseases and in developed AIDS syndrome. In addition to the reduced defence capacities of the organism favourable conditions are created e.g. by antibiotic treatment, treatment with female hormones, unsuitable clothing, obesity, a certain part is played also by occupational predisposition. Treatment of onychomycoses is complicated and difficult. Before griseofulvin was available there was only surgical ablation and treatment with keratolytics. At present a number of substances with marked fungistatic effects is available. The author mentions: griseofulvin, ketoconazole, fluconazole, itraconazole (azole derivatives), allylamines (terbinafine-Lamisil). He discusses the mode of administration, dosage and undesirable effects. The recent antimycotics are ciclopiroxolamines (Batrafen) and amorolfin (Loceryl) in the form of lac.
Insights
Mycotic skin infections are increasing due to opportunistic fungi, especially in immunocompromised patients. New antifungal treatments offer improved options for difficult-to-treat conditions like onychomycosis.
Area of Science:
- Dermatology
- Mycology
- Infectious Diseases
Context:
- Rising incidence of mycotic infections affecting skin and adnexa.
- Increased prevalence in immunocompromised individuals undergoing immunosuppressive therapy (oncological, oncohematological diseases, AIDS).
- Contributing factors include antibiotic use, hormone therapy, obesity, and occupational predispositions.
Purpose:
- To review the current landscape of mycotic infections.
- To discuss the challenges in treating onychomycosis.
- To present available and novel antifungal agents.
Summary:
- Mycotic infections are increasingly caused by opportunistic fungi, particularly in patients with compromised immunity.
- Treatment of onychomycosis remains complex, with historical methods including surgical ablation and keratolytics.
- Current therapeutic options include griseofulvin, azole derivatives (ketoconazole, fluconazole, itraconazole), allylamines (terbinafine), ciclopiroxolamines, and amorolfin.
Impact:
- Highlights the growing threat of fungal infections in clinical settings.
- Emphasizes the need for effective and accessible antifungal treatments.
- Provides an overview of established and emerging antimycotic agents for clinical consideration.
