ICD-10: B60.19

ICD-10 code B60.19 refers to "Other acanthamebic disease," which is part of the broader category of acanthamebiasis, a disease caused by the protozoan parasite Acanthamoeba. This organism is commonly found in the environment, particularly in soil and water, and can lead to various infections, primarily affecting the eyes and central nervous system.

Clinical Description

Overview of Acanthamoeba

Acanthamoeba is a free-living amoeba that can cause opportunistic infections in humans, particularly in individuals with compromised immune systems or those who engage in certain risk behaviors, such as contact lens wearers. The infections can manifest in several forms, with the most notable being:

• Acanthamoebic keratitis: An infection of the cornea, often associated with contact lens use.
• Granulomatous amebic encephalitis (GAE): A severe brain infection that can occur in immunocompromised individuals.

Other Acanthamebic Diseases

The term "Other acanthamebic disease" encompasses various clinical manifestations of Acanthamoeba infections that do not fit into the more commonly recognized categories. These may include:

• Skin infections: Acanthamoeba can cause skin lesions, particularly in immunocompromised patients or those with open wounds.
• Sinusitis: Rarely, Acanthamoeba can infect the sinuses, leading to symptoms similar to those of bacterial sinusitis.
• Disseminated infections: In severely immunocompromised patients, Acanthamoeba can spread to multiple organs, leading to systemic illness.

Symptoms

Symptoms of acanthamebic diseases can vary widely depending on the site of infection:

• Ocular symptoms: Redness, pain, blurred vision, and sensitivity to light in cases of keratitis.
• Neurological symptoms: Headaches, fever, confusion, and seizures in cases of GAE.
• Skin symptoms: Red, swollen lesions that may be painful or itchy.

Risk Factors

Several factors increase the risk of developing acanthamebic diseases, including:

• Contact lens wear: Particularly with improper hygiene or extended wear.
• Immunocompromised states: Conditions such as HIV/AIDS, diabetes, or use of immunosuppressive medications.
• Exposure to contaminated water: Swimming in freshwater lakes or using non-sterile water for rinsing contact lenses.

Diagnosis and Management

Diagnosis typically involves clinical evaluation, patient history, and laboratory tests, including:

• Corneal scraping: For suspected keratitis, to identify Acanthamoeba.
• Imaging studies: MRI or CT scans for suspected GAE.

Management strategies depend on the type and severity of the infection:

• Topical medications: Antimicrobial eye drops for keratitis.
• Systemic therapy: Antifungal or antiparasitic medications for more severe infections, particularly in cases of GAE.

Conclusion

ICD-10 code B60.19 captures the complexity of acanthamebic diseases beyond the more common presentations. Understanding the various manifestations, risk factors, and management strategies is crucial for healthcare providers to effectively diagnose and treat these infections.
