B77.81
Ascariasis pneumonia
Clinical Classification Guidelines
Medical Intelligence & Overview
Ascariasis pneumonia is a lung infection caused by the parasitic roundworm Ascaris lumbricoides. This condition results from the migration of the parasite's larvae through the lungs, leading to respiratory symptoms and complications. Although most commonly associated with intestinal infection, ascariasis can sometimes manifest with pulmonary involvement, particularly when the larvae migrate through lung tissue. Recognizing this condition is important for timely diagnosis and treatment, especially in areas where parasitic infections are common.
Causes & Symptoms
Clinical Causes: Infection with the Ascaris lumbricoides parasite, transmitted via ingestion of contaminated food or water containing eggs Larval migration through the gastrointestinal tract to the lungs during the parasite's lifecycle Poor sanitation and hygiene practices that increase exposure to contaminated soil or objects Increased susceptibility in individuals living in endemic regions with inadequate sanitation infrastructure
Key Symptoms: Cough, often dry or with mucus production Chest discomfort or pain Shortness of breath or difficulty breathing Wheezing or crackling sounds on auscultation Low-grade fever Fatigue and general malaise Occasional blood-streaked sputum
Diagnostic & Treatment
Diagnosis Path: Physical examination to detect respiratory signs Chest X-ray to identify infiltrates or eosinophilic pneumonia Stool tests to detect Ascaris eggs, confirming intestinal infection Blood tests showing eosinophilia (increased eosinophil count) Serological tests or sputum analysis may also be used for confirmation
Treatment Protocols: Anthelmintic drugs such as albendazole or mebendazole to eliminate the Ascaris worms Symptomatic treatment with antitussives or analgesics as needed Monitoring and supportive care for respiratory function, including oxygen therapy if necessary Addressing underlying environmental factors through improved sanitation and hygiene practices
