ICD-10: B77.81

Ascariasis pneumonia, classified under ICD-10 code B77.81, is a rare but significant manifestation of ascariasis, an infection caused by the parasitic roundworm Ascaris lumbricoides. This condition typically arises when the larvae of the parasite migrate through the lungs, leading to respiratory symptoms. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with ascariasis pneumonia.

Clinical Presentation

Pathophysiology

Ascariasis pneumonia occurs when Ascaris lumbricoides larvae penetrate the intestinal wall and enter the bloodstream, eventually migrating to the lungs. This migration can cause a range of respiratory symptoms due to the inflammatory response in the lung tissue, which may lead to pneumonia-like symptoms.

Signs and Symptoms

Patients with ascariasis pneumonia may present with a variety of respiratory and systemic symptoms, including:

• Cough: Often persistent and may be productive, sometimes with sputum that can be blood-tinged.
• Dyspnea: Shortness of breath is common, particularly during exertion.
• Chest Pain: Patients may experience pleuritic chest pain due to lung inflammation.
• Fever: Low-grade fever is frequently observed, indicating an inflammatory response.
• Wheezing: This may occur due to bronchial obstruction or inflammation.
• Fatigue: General malaise and fatigue are common as the body fights the infection.

Additional Symptoms

In some cases, patients may also exhibit gastrointestinal symptoms, such as:

• Abdominal Pain: Discomfort or pain in the abdominal region may occur due to the presence of adult worms in the intestines.
• Nausea and Vomiting: These symptoms can arise from the gastrointestinal involvement of the infection.

Patient Characteristics

Demographics

Ascariasis is more prevalent in tropical and subtropical regions, particularly in areas with poor sanitation. Patient characteristics often include:

• Age: Ascariasis primarily affects children, but adults can also be infected. The migration of larvae to the lungs can occur in any age group.

Ascariasis pneumonia, classified under ICD-10 code B77.81, is a condition resulting from the migration of Ascaris lumbricoides, a parasitic roundworm, into the lungs. This can occur as part of the life cycle of the parasite, which typically begins in the intestines. Understanding the standard treatment approaches for this condition involves a combination of antiparasitic medications, supportive care, and management of respiratory symptoms.

Overview of Ascariasis

Ascariasis is one of the most common helminthic infections worldwide, particularly in tropical and subtropical regions. The adult worms reside in the intestines, but their larvae can migrate through the bloodstream to the lungs, leading to respiratory symptoms such as cough, wheezing, and difficulty breathing. This migration can cause a condition known as ascariasis pneumonia, which may present with symptoms similar to other respiratory infections.

Standard Treatment Approaches

1. Antiparasitic Medications

The cornerstone of treatment for ascariasis pneumonia is the use of antiparasitic drugs. The following medications are commonly prescribed:

• Albendazole: This is often the first-line treatment. It works by inhibiting the growth and reproduction of the worms, leading to their eventual death and expulsion from the body. A typical dose for adults is 400 mg taken once, while children may receive a lower dose based on weight.

• Mebendazole: Another effective option, mebendazole is similar in action to albendazole. The usual dosage is 100 mg taken twice daily for three days.

• Ivermectin: In some cases, ivermectin may be used, particularly if there is a co-infection with other parasites. It is effective against a variety of helminths and is typically administered as a single dose.

2. Supportive Care

In addition to antiparasitic treatment, supportive care is crucial, especially for patients experiencing significant respiratory distress. This may include:

• Bronchodilators: Medications such as albuterol can help relieve bronchospasm and improve airflow in patients with wheezing or difficulty breathing.

• Corticosteroids: In cases of severe inflammation or allergic reactions in the lungs, corticosteroids may be prescribed to reduce inflammation and improve respiratory function.

• Oxygen Therapy: For patients with significant hypoxia (low oxygen levels), supplemental oxygen may be necessary to ensure adequate oxygenation.

3. Monitoring and Follow-Up

Patients diagnosed with ascariasis pneumonia should be closely monitored for:

• Response to Treatment: Follow-up visits are essential to assess the effectiveness of the antiparasitic therapy and to monitor for any potential side effects.

• Resolution of Symptoms: Improvement in respiratory symptoms should be evaluated, and any persistent or worsening symptoms should prompt further investigation.

• Prevention of Re-infection: Education on hygiene and sanitation practices is vital to prevent re-infection, as Ascaris eggs are commonly transmitted through contaminated food and water.

Conclusion

The management of ascariasis pneumonia involves a comprehensive approach that includes effective antiparasitic treatment, supportive care for respiratory symptoms, and ongoing monitoring. Early diagnosis and treatment are crucial to prevent complications and ensure a favorable outcome. Patients should also receive education on preventive measures to reduce the risk of future infections. If you suspect ascariasis pneumonia or have related symptoms, it is important to seek medical attention promptly for appropriate evaluation and treatment.

Clinical Description of ICD-10 Code B77.81: Ascariasis Pneumonia

Overview of Ascariasis
Ascariasis is an infection caused by the parasitic roundworm Ascaris lumbricoides, which is one of the most common human helminthic infections worldwide. The adult worms reside in the intestines, but their life cycle includes a larval stage that can migrate through various tissues, including the lungs. This migration can lead to a condition known as ascariasis pneumonia, which is classified under the ICD-10 code B77.81.

Pathophysiology
The life cycle of Ascaris lumbricoides begins when eggs are ingested, typically through contaminated food or water. Once ingested, the eggs hatch in the intestines, releasing larvae that penetrate the intestinal wall and enter the bloodstream. From there, the larvae travel to the lungs, where they can cause respiratory symptoms as they migrate through the alveoli and bronchi. This pulmonary phase can lead to inflammation and respiratory distress, manifesting as ascariasis pneumonia.

Clinical Features

Symptoms
Patients with ascariasis pneumonia may present with a variety of respiratory symptoms, including:
- Cough (which may be productive)
- Wheezing
- Shortness of breath
- Chest pain
- Fever

These symptoms can mimic other respiratory conditions, making diagnosis challenging without a thorough clinical history and appropriate diagnostic tests.

Diagnosis
Diagnosis of ascariasis pneumonia typically involves:
- Clinical History: A history of exposure to contaminated food or water, particularly in endemic areas.
- Imaging Studies: Chest X-rays or CT scans may reveal infiltrates or other abnormalities consistent with pneumonia.
