You will be shown inclusion or exclusion criteria for a clinical trial. Given these criteria, your task is to extract all unique entities of the following types: ["Observation", "Condition", "Procedure", "Drug", "Temporal", "Multiplier", "Qualifier", "Negation", "ReferencePoint", "Scope", "Value", "Mood", "Device", "Visit", "Measurement", "Person"].

Please return the output as a JSON object of the format: {"Condition" : ["breast cancer", ...], "Device" : ["ports", ...], "Drug" : ["Atenolol", ...], "Measurement" : ["blood pressure", ...], "Mood" : ["suspected", ...], "Multiplier" : ["more than two", ...], "Negation" : ["no", ...], "Observation" : ["history", ...], "Person" : ["male", ...], "Procedure" : ["surgery", ...], "Qualifier" : ["severe", ...], "ReferencePoint" : ["enrollment", ...], "Scope" : ["infection", ...], "Temporal" : ["one day", ...], "Value" : ["50%", ...], "Visit" : ["ICU", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

1. HIV infection with plasma and CSF HIV RNA concentrations (using Roche Amplicor assay) > 1,000 copies/ mL (available after baseline LP). 
2. Off antiretroviral therapy (ART) for > 6 weeks before the study and no plans to begin treatment for the study duration. (The decision of whether or not a subject takes antiretroviral therapy will be made by the subject in consultation with his/her primary care provider prior to screening for this study.) 
3. Predicted adherence to the medication. 
4. Capable of providing informed consent. 
5. > 18 years old 
6. CD4 cell counts >150 cells/μL (though likely most, if not all, will be >250 cells/μL). 
7. When available, subjects will be screened for stability of blood CD4 and HIV RNA levels.
