Treatment of AIDS with Cryptococcal Meningitis or Asymptomatic Cryptococcal Antigenemia

This protocol covers the management of acquired immunodeficiency syndrome presenting alongside cryptococcal meningitis or asymptomatic cryptococcal antigenemia with a negative lumbar puncture — two distinct clinical situations that each require a specific, sequenced approach.

Clinical Scenario

The person with AIDS presents with one of the following:

Cryptococcal meningitis — active CNS fungal infection requiring coordinated management of infection and immune reconstitution, with close monitoring for increased intracranial pressure.
Asymptomatic cryptococcal antigenemia with a negative lumbar puncture — elevated antigen burden without confirmed meningitis on lumbar puncture, directing a distinct treatment pathway.

Treatment Approach (Partial Overview)

For cryptococcal meningitis, antifungal therapy is started first alongside active management of increased intracranial pressure; antiretroviral therapy is introduced after a period determined by the patient's clinical response and specific criteria — the timing and criteria differ based on whether certain clinical milestones have been reached.

For asymptomatic cryptococcal antigenemia with a negative lumbar puncture, immediate antiretroviral therapy combined with preemptive antifungal coverage is indicated. The complete selection, sequencing, and decision criteria for both scenarios are in the full protocol.

Clinical Goals

For persons with cryptococcal meningitis who can be closely monitored and treated for increased intracranial pressure and immune reconstitution inflammatory syndrome, ART initiation is recommended within 2 to 4 weeks after starting antifungal therapy, with earlier initiation at 2 weeks after starting antifungal therapy for those who have clinically improved, have control of intracranial pressure, have negative CSF cultures with use of antifungal therapy, and can continue to be closely monitored; those who do not meet these criteria should initiate ART 4 weeks after starting antifungal therapy (evidence rating: BIII).

For ART-naive individuals with asymptomatic cryptococcal antigenemia and a negative lumbar puncture, immediate ART and preemptive fluconazole are recommended (evidence rating: BIII).

All patients should be closely monitored and treated for increased intracranial pressure.
