Human lagochilascariasis-A rare helminthic disease

Area of Science:

• Medical Parasitology
• Infectious Diseases
• Tropical Medicine

Background:

• Lagochilascariasis is a parasitic disease caused by the helminth genus Lagochilascaris.
• Lagochilascaris minor is the only species implicated in human infections.
• Most human cases in the Americas are reported in Brazil.

Purpose of the Study:

• To summarize the key features of human lagochilascariasis.
• To describe the etiologic agent, Lagochilascaris minor.
• To review the disease's prevalence, life cycle, clinical course, and treatment.

Main Methods:

• Literature review of existing studies on lagochilascariasis.
• Compilation of data on prevalence, host-parasite interactions, and clinical manifestations.
• Analysis of reported treatment outcomes and disease chronicity.

Main Results:

• Lagochilascariasis is a chronic disease, often persisting for years.
• The parasite, L. minor, burrows into subcutaneous tissues, paranasal sinuses, and mastoid areas.
• L. minor can migrate extensively, causing tissue destruction, including bone, and has led to fatal outcomes when reaching lungs or CNS.

Conclusions:

• Lagochilascariasis is a significant parasitic disease with a predilection for Brazil.
• The parasite's migratory and destructive capabilities pose diagnostic and therapeutic challenges.
• Current treatments are often palliative, highlighting the need for further research into effective interventions.
