Mycetoma: reviewing a neglected disease

Area of Science:

• Medical Mycology
• Infectious Diseases
• Tropical Medicine

Background:

• Mycetoma, caused by fungi (eumycotic) or bacteria (actinomycotic), is a neglected tropical disease with high morbidity and socioeconomic impact.
• Characterized by subcutaneous tissue infection, it presents as woody swellings, discharging sinuses, and grains, potentially leading to permanent disability if untreated.
• Affects men more than women, predominantly the leg, with various fungal and bacterial species implicated.

Purpose of the Study:

• To provide a comprehensive overview of mycetoma, encompassing its causative agents, clinical presentation, diagnostic methods, treatment approaches, and prevention strategies.
• To highlight the importance of early diagnosis and intervention in managing mycetoma and reducing its associated burden.
• To emphasize the role of molecular diagnostics in accurate and timely identification of causative organisms.

Main Methods:

• Review of literature on mycetoma, including causative agents, clinical features, diagnostic modalities, and treatment outcomes.
• Discussion of diagnostic techniques, from traditional microscopy and culture to advanced molecular methods like PCR and sequencing.
• Analysis of treatment strategies, considering both antimicrobial and surgical interventions, as well as rehabilitation.

Main Results:

• Mycetoma diagnosis relies on grain examination, microscopy, imaging (radiography, ultrasonography, MRI), culture, and molecular methods (PCR, sequencing).
• Molecular sequencing is vital for rapid, accurate diagnosis, particularly in culture-negative cases.
• Treatment is lengthy, with better outcomes in actinomycetoma than eumycetoma, often requiring a multidisciplinary approach.

Conclusions:

• Mycetoma is a preventable and treatable neglected tropical disease, but requires prompt diagnosis and management to mitigate its severe consequences.
• Effective management involves a holistic approach combining antimicrobials, surgery, and rehabilitation.
• Prevention through protective measures like wearing appropriate footwear is essential, especially in endemic areas.
