New aspects of some endemic mycoses

Area of Science:

• Medical Mycology
• Infectious Diseases
• Pharmacology

Background:

• Mycetomas, fungal and actinomycotic infections, exhibit diverse clinical presentations and etiologies.
• Treatment strategies for mycetomas are contingent upon the causative agent and patient's clinical status.
• The 1990s saw a significant surge in coccidioidomycosis cases in California, affecting both endemic and non-endemic regions.

Purpose of the Study:

• To review and outline current treatment modalities for eumycetomas and actinomycetomas.
• To investigate the factors contributing to the 1990s coccidioidomycosis outbreak in California.
• To highlight the challenges in defining a definitive cure criterion for mycetomas.

Main Methods:

• Literature review of established and emerging treatment protocols for mycetomas.
• Analysis of epidemiological data and contributing factors for the coccidioidomycosis outbreak.
• Clinical outcome assessment based on available literature, noting the absence of a universal cure criterion.

Main Results:

• Itraconazole is preferred over ketoconazole for eumycetomas due to efficacy and tolerability.
• Actinomycetomas necessitate varied antibiotic combinations, including dapsone with sulfamethoxazole-trimethoprim (SMT) for Nocardia, amikacin plus SMT for Actinomadura madurae, and ciprofloxacin for bone lesions.
• The coccidioidomycosis outbreak was linked to environmental factors (drought, rainfall), increased susceptible populations, construction, and improved diagnostics, with an unusual rise in acute respiratory failure cases.

Conclusions:

• Optimal treatment for mycetomas requires tailored approaches based on specific pathogens and disease severity.
• Environmental and demographic shifts significantly influenced the coccidioidomycosis epidemic in California.
• Further research is needed to establish standardized cure criteria for mycetoma infections.
