Parasitic worm infections cause pulmonary eosinophilia, an increase in eosinophils in the lungs. Early diagnosis and antiparasitic drugs are key to reducing illness from these global health threats.

Area of Science:

  • Medical Science
  • Parasitology
  • Pulmonology

Background:

  • Parasitic infections are globally prevalent, affecting diverse populations due to travel and migration.
  • Worm infections impose a significant health burden, particularly on impoverished and immunocompromised individuals.
  • Pulmonary eosinophilia is a common manifestation across various metazoan infections.

Purpose of the Study:

  • To review common and uncommon causes of pulmonary parasitic eosinophilia.
  • To discuss the clinical manifestations, diagnostic approaches, and management strategies for these conditions.
  • To highlight the importance of awareness and interventions in mitigating parasitic lung disease.

Main Methods:

  • Literature review of parasitic infections causing pulmonary eosinophilia.

  • Analysis of common causative agents like Strongyloides, Ascaris, Toxocara, and Ancylostoma.
  • Focus on severe forms such as tropical pulmonary eosinophilia caused by filarial worms.

    • Main Results:

    • Nematode larval migration commonly causes transient pulmonary eosinophilia without permanent lung damage.
    • Conditions like Löffler's syndrome, visceral larva migrans, and tropical pulmonary eosinophilia are key presentations.
    • Tropical pulmonary eosinophilia, caused by Wuchereria bancrofti and Brugia malayi, can mimic asthma.

    Conclusions:

    • Pulmonary parasitic eosinophilia requires increased awareness, improved diagnostics, and effective antiparasitic treatments.
    • Preventative measures and prompt management are crucial for reducing morbidity and mortality.
    • This review provides insights into the diagnosis and management of parasitic lung diseases.
