ICD-10: B78.7

Disseminated strongyloidiasis, classified under ICD-10 code B78.7, is a severe form of strongyloidiasis, a parasitic infection caused by the nematode Strongyloides stercoralis. This condition is characterized by the widespread dissemination of the parasite throughout the body, leading to significant clinical manifestations.

Clinical Description

Etiology

Strongyloides stercoralis is primarily transmitted through skin contact with contaminated soil, particularly in tropical and subtropical regions. The larvae penetrate the skin, migrate through the bloodstream, and can establish infection in the intestines. In immunocompromised individuals, the infection can disseminate beyond the gastrointestinal tract, leading to severe complications.

Symptoms

Disseminated strongyloidiasis can present with a variety of symptoms, which may include:

• Gastrointestinal Symptoms: Abdominal pain, diarrhea, and weight loss are common as the parasite affects the intestinal lining.
• Respiratory Symptoms: Cough, wheezing, and pulmonary infiltrates may occur due to the migration of larvae through the lungs.
• Dermatological Symptoms: Rashes or urticaria can develop as a result of the immune response to the parasite.
• Systemic Symptoms: Fever, malaise, and fatigue are often reported, particularly in cases of severe infection.

Complications

In severe cases, disseminated strongyloidiasis can lead to life-threatening complications, including:

• Septic Shock: Due to secondary bacterial infections.
• Meningitis: Rarely, the larvae can invade the central nervous system.
• Acute Respiratory Distress Syndrome (ARDS): Resulting from pulmonary involvement.

Diagnosis

Diagnosis of disseminated strongyloidiasis typically involves:

• Serological Tests: Detection of antibodies against Strongyloides stercoralis.
• Stool Examination: Identification of larvae in stool samples, although this may be negative in disseminated cases.
• Biopsy: In some instances, tissue biopsy may be necessary to confirm the presence of the parasite.

Treatment

The primary treatment for disseminated strongyloidiasis is the use of antiparasitic medications, with ivermectin being the drug of choice. In cases of severe infection, supportive care and management of complications are critical.

Conclusion

Disseminated strongyloidiasis (ICD-10 code B78.7) is a serious condition that requires prompt diagnosis and treatment to prevent severe complications. Awareness of the symptoms and risk factors associated with Strongyloides stercoralis infection is essential for effective management, particularly in immunocompromised patients.

This condition can lead to significant morbidity, particularly in immunocompromised individuals. Understanding the standard treatment approaches for disseminated strongyloidiasis is crucial for effective management and patient outcomes.

Overview of Disseminated Strongyloidiasis

Disseminated strongyloidiasis occurs when the Strongyloides stercoralis larvae invade multiple organs, leading to systemic symptoms. This condition is particularly dangerous because it can result in hyperinfection syndrome, where the parasite proliferates uncontrollably, often leading to severe complications such as septic shock and multi-organ failure[1].

Standard Treatment Approaches

1. Antiparasitic Medications

The cornerstone of treatment for disseminated strongyloidiasis is the use of antiparasitic medications. The following drugs are commonly employed:

• Ivermectin: This is the first-line treatment for strongyloidiasis. Ivermectin is effective in killing the adult worms and larvae. The typical dosage for disseminated strongyloidiasis is 200 micrograms per kilogram of body weight, administered as a single dose or in multiple doses depending on the severity of the infection[1][2].

• Albendazole: While not as effective as ivermectin, albendazole can be used as an alternative, especially in cases where ivermectin is contraindicated. The usual dosage is 400 mg taken twice daily for 3 days[2].

2. Supportive Care

Patients with disseminated strongyloidiasis often require supportive care, particularly if they present with severe symptoms or complications. This may include:

• Fluid Resuscitation: To manage dehydration and maintain hemodynamic stability, especially in cases of septic shock[1].

• Nutritional Support: Patients may require nutritional support, particularly if gastrointestinal symptoms are present, leading to malabsorption or significant weight loss[1].

• Management of Complications: Addressing any complications such as pneumonia, sepsis, or other organ dysfunction is critical. This may involve the use of antibiotics for secondary infections and other supportive measures tailored to the patient's needs[2].

3. Monitoring and Follow-Up

Close monitoring of the patient’s clinical status is essential during treatment. Follow-up evaluations may include:

• Repeat Stool Tests: To confirm the eradication of the parasite, stool examinations should be conducted after treatment completion[1].

• Assessment of Symptoms: Continuous assessment of symptoms and overall health status is necessary to ensure that the treatment is effective and to identify any potential complications early[2].

Conclusion

Disseminated strongyloidiasis is a serious condition that requires prompt and effective treatment. The primary approach involves the use of antiparasitic medications, particularly ivermectin, along with supportive care to manage symptoms and complications. Regular monitoring and follow-up are essential to ensure successful treatment outcomes. Given the potential for severe complications, especially in immunocompromised patients, timely intervention is critical for improving prognosis and reducing morbidity associated with this infection.
