Title: A Phase IV Study of Antiretroviral Therapy for HIV Infected Adults Presenting With Acute Opportunistic Infections: Immediate Versus Deferred Initiation of Antiretroviral Therapy
Brief Summary: The purpose of this study is to evaluate the effect of starting anti-HIV drugs in HIV infected patients who are being treated for opportunistic infections (OIs). This study will follow two patient groups: those who received anti-HIV drugs soon after being diagnosed with an OI and patients with OIs who deferred beginning anti-HIV drugs until after recovering from the OI.

* Confirmed Cryptococcal meningitis on the current admission by India ink or CSF cryptococcal antigen
* ART naive at the time of enrollment
* 21 years old and above
* Ability and willingness to give written informed consent to participate in the study
* Able (as assessed by the patient's medical team)to initiate amphotericin B for cryptococcal meningitis
* Initiated amphotericin B 72 hours or less prior to assessment for enrollment or not on amphotericin B at the time of assessment for enrollment
* Agrees to obtain outpatient care after discharge within 50 kilometers from Princess Marina Hospital,Scottish Livingstone Hospital and Bamalete Lutheran Hospital

Exclusion Criteria:

* Recent (within the past 4 weeks) antifungal use
* Pregnant or breastfeeding
* Initiated anti-tubercular therapy 2 weeks or less prior to assessment for enrollment.
* Bacterial meningitis at the time of assessment for enrollment.
* Recent (within the past 1 month) use of the following:systemic cancer chemotherapy,oral or intravenous corticosteroids or other immunomodulators.
* Judged by study coordinator to be likely to initiate chemotherapy or any other immunomodulatory therapy prior to the 4 week LP.
* Imprisoned.

Participants who have tuberculosis (TB) alone are ineligible for this study. Participants with bacterial pneumonia or serious BI must have a CD4 count less than 200 cells/mm3 within 30 days prior to study entry. Participants with other serious OIs, including other AIDS-defining and -related OIs for which appropriate therapy other than ART exists are eligible, pending investigator approval. Participants' current OI treatment must have been started within 14 days prior to study entry, but may have been discontinued prior to study entry.

* Systemic cancer chemotherapy within 30 days prior to study entry
* Immunomodulators within 30 days prior to study entry, including growth factors, immune globulin, interleukins, and interferons (unless for hepatitis C virus or Kaposi's sarcoma)
* Investigational ARV agents at study entry
* Systemic investigational agents (except ARV drugs) within 30 days prior to study entry will be allowed at the study official's discretion
* Anticipated use of certain medications
* Kidney failure requiring dialysis
* Current drug or alcohol use that, in the opinion of the study official, would interfere with the study
* Treatment for current, first-treated, and diagnosed OI or BI for more than 14 days prior to study entry
