ICD-10: B60.10

Acanthamebiasis, indicated by the ICD-10 code B60.10, is an infection caused by the Acanthamoeba species, which can lead to serious health issues, particularly affecting the eyes and central nervous system. This condition is often associated with contact lens wear, but it can also occur in immunocompromised individuals or those exposed to contaminated water sources. Here’s a detailed overview of the standard treatment approaches for this condition.

Overview of Acanthamebiasis

Acanthamebiasis can manifest in two primary forms: ocular and extraocular. The ocular form typically presents as a severe keratitis, which can lead to vision loss if not treated promptly. The extraocular form can affect the skin, lungs, and central nervous system, particularly in immunocompromised patients.

Standard Treatment Approaches

1. Ocular Acanthamebiasis Treatment

The treatment for ocular acanthamebiasis primarily involves:

• Topical Antimicrobials: The first line of treatment usually includes the use of topical medications such as:
• Biguanides: Chlorhexidine and Polyhexamethylene biguanide (PHMB) are commonly used due to their effectiveness against Acanthamoeba.

• Aminoglycosides: Neomycin and Gentamicin may also be prescribed to enhance treatment efficacy.

• Corticosteroids: In some cases, corticosteroids may be used to reduce inflammation, but they should be administered cautiously as they can exacerbate the infection if not used appropriately.

• Surgical Intervention: In severe cases where medical therapy fails, surgical options such as corneal debridement or even corneal transplantation may be necessary to restore vision and remove infected tissue.

2. Extraocular Acanthamebiasis Treatment

For extraocular infections, treatment strategies may include:

• Systemic Antimicrobials: Depending on the site of infection, systemic treatment may involve:

• Oral or intravenous medications: Such as itraconazole or pentamidine, particularly in cases involving the central nervous system or disseminated disease.

• Supportive Care: Patients may require supportive care, especially if they are immunocompromised. This can include hydration, nutritional support, and management of any underlying conditions.

3. Preventive Measures

Preventive strategies are crucial, especially for individuals at risk:

• Proper Contact Lens Hygiene: Ensuring that contact lenses are cleaned and stored properly can significantly reduce the risk of ocular acanthamebiasis.
• Avoiding Contaminated Water: Individuals should avoid exposing their eyes to potentially contaminated water sources, such as lakes or hot tubs.

Conclusion

The management of acanthamebiasis, particularly ocular forms, requires a combination of topical and systemic therapies tailored to the severity of the infection. Early diagnosis and treatment are critical to prevent complications, including vision loss. For those at risk, adherence to preventive measures is essential to mitigate the chances of infection. If you suspect an infection or experience symptoms, it is vital to seek medical attention promptly to initiate appropriate treatment.

Acanthamebiasis is an infection caused by the protozoan parasite Acanthamoeba, which is commonly found in soil, water, and air. The ICD-10-CM code B60.10 specifically refers to "Acanthamebiasis, unspecified," indicating that the diagnosis does not specify the site of infection or the clinical manifestations associated with the disease.

Clinical Description

Etiology

Acanthamoeba is a free-living amoeba that can cause a range of diseases, primarily affecting the eyes and central nervous system. The infection is often associated with contact lens wear, particularly when lenses are improperly cleaned or stored, leading to keratitis. However, Acanthamoeba can also cause granulomatous amebic encephalitis (GAE), which is a severe and often fatal condition affecting the brain.

• Ocular Acanthamebiasis (Keratitis): Symptoms may include:
• Eye pain
• Redness
• Blurred vision
• Sensitivity to light (photophobia)

• Tearing and discharge

• Central Nervous System Acanthamebiasis (GAE): Symptoms may include:

• Headaches
• Fever
• Nausea and vomiting
• Altered mental status
• Seizures

Diagnosis

Diagnosis of Acanthamebiasis typically involves:
- Clinical evaluation of symptoms and history, particularly contact lens use.
- Microscopic examination of corneal scrapings or tissue samples.
- Culture of the organism from clinical specimens.
- PCR (polymerase chain reaction) testing for more definitive identification.

Treatment

Treatment for Acanthamebiasis can be challenging and may include:
- Antimicrobial therapy, often involving a combination of medications such as:
- Propamidine isethionate
- Neomycin
- Chlorhexidine
- In severe cases, surgical intervention, such as corneal transplantation, may be necessary.
