ICD-10: B77.0

Ascariasis is a parasitic infection caused by the roundworm Ascaris lumbricoides, which is one of the most common helminthic infections worldwide. The ICD-10 code B77.0 specifically refers to "Ascariasis with intestinal complications," indicating that the infection has led to significant gastrointestinal issues.

Clinical Description of Ascariasis

Etiology

Ascaris lumbricoides is transmitted through the fecal-oral route, primarily via contaminated food or water. The eggs of the parasite are ingested, hatch in the intestine, and the larvae migrate through the bloodstream to the lungs before returning to the intestines to mature into adult worms.

Symptoms

While many individuals with ascariasis may remain asymptomatic, those who do exhibit symptoms can experience a range of gastrointestinal complications, including:

• Abdominal Pain: Often crampy and can be severe.
• Nausea and Vomiting: Resulting from intestinal obstruction or irritation.
• Diarrhea: May occur, sometimes with the presence of worms in the stool.
• Intestinal Obstruction: A serious complication where a large number of worms can block the intestines, leading to severe pain and potential perforation.
• Malnutrition: Due to the worms consuming nutrients from the host.

Diagnosis

Diagnosis of ascariasis typically involves:

• Stool Examination: Microscopic identification of Ascaris eggs in stool samples.
• Imaging Studies: Ultrasound or CT scans may be used to identify intestinal obstructions or other complications.

The ICD-10 code B77.0 specifically refers to cases of ascariasis that present with complications affecting the intestines. Understanding the standard treatment approaches for this condition is crucial for effective management and patient care.

Overview of Ascariasis

Ascariasis is one of the most common helminthic infections worldwide, particularly in tropical and subtropical regions. The infection occurs when a person ingests eggs of the Ascaris worm, which can lead to various gastrointestinal symptoms, including abdominal pain, malnutrition, and intestinal obstruction, especially in severe cases[1][2].

Standard Treatment Approaches

1. Antiparasitic Medications

The primary treatment for ascariasis involves the use of antiparasitic medications. The most commonly prescribed drugs include:

• Albendazole: This is often the first-line treatment. It works by inhibiting the worm's ability to absorb glucose, leading to its death. A single dose of 400 mg is typically effective[3].
• Mebendazole: Another effective option, mebendazole is administered in a similar manner, usually as a single dose of 500 mg or in a course of 100 mg twice daily for three days[4].
• Ivermectin: In some cases, ivermectin may be used, particularly in areas where resistance to other medications is noted. It is effective against a range of parasitic infections, including ascariasis[5].

2. Management of Complications

In cases where ascariasis leads to intestinal complications, such as obstruction or perforation, additional interventions may be necessary:

• Surgical Intervention: If there is a significant obstruction or perforation of the intestine, surgical intervention may be required to remove the worms or repair the intestinal damage. This is particularly critical in severe cases where conservative management fails[6].
• Supportive Care: Patients may require supportive care, including hydration and nutritional support, especially if they present with malnutrition or dehydration due to prolonged gastrointestinal symptoms[7].

3. Follow-Up and Monitoring

Post-treatment follow-up is essential to ensure the complete resolution of the infection and to monitor for any potential recurrence. This may involve:

• Stool Examination: Regular stool tests to check for the presence of eggs or adult worms can help confirm the effectiveness of treatment and detect any reinfection[8].
• Education and Prevention: Educating patients about hygiene practices, such as proper handwashing and safe food handling, is crucial to prevent reinfection and control the spread of ascariasis in endemic areas[9].

Conclusion

The management of ascariasis with intestinal complications (ICD-10 code B77.0) primarily revolves around the use of antiparasitic medications, with surgical intervention as a necessary option in severe cases. Effective treatment not only alleviates symptoms but also prevents further complications. Continuous monitoring and patient education play vital roles in ensuring successful outcomes and reducing the risk of reinfection. For individuals in endemic regions, awareness and preventive measures are key to controlling the spread of this parasitic infection.
