Cryptococcal chorioretinitis with immune reconstitution inflammatory syndrome

Area of Science:

• Immunology
• Infectious Diseases
• Ophthalmology

Background:

• Immune Reconstitution Inflammatory Syndrome (IRIS) is a clinical phenomenon observed during immune restoration in immunocompromised individuals.
• IRIS is frequently associated with opportunistic infections, particularly in human immunodeficiency virus (HIV) patients initiating antiretroviral therapy (ART).
• Cryptococcosis is a common opportunistic infection in HIV patients, and IRIS has been reported in 30-35% of these cases upon ART initiation.

Observation:

• This report details a specific case of IRIS.
• The IRIS manifestation was localized to the eye.
• The underlying cause was a secondary reaction to a prior cryptococcal infection.

Findings:

• The case presented demonstrates a rare ocular localization of Immune Reconstitution Inflammatory Syndrome.
• This specific instance of IRIS occurred subsequent to the treatment of cryptococcal infection in an HIV-positive individual.
• The ocular inflammation developed during the phase of immune system recovery.

Implications:

• This case underscores the importance of considering IRIS in the differential diagnosis of ocular inflammation in HIV patients with a history of opportunistic infections.
• Ocular IRIS secondary to cryptococcosis may present unique diagnostic and management challenges.
• Further investigation into the specific mechanisms and clinical spectrum of ocular IRIS is warranted.
