When to Start Anti-HIV Drugs in Patients With Opportunistic Infections
When to Start Anti-HIV Drugs in Patients With Opportunistic Infections
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.
Despite the advent of highly active antiretroviral therapy (HAART), many HIV infected
 patients without access to antiretroviral therapy (ART) present with acute OIs. Such
 presentations pose a management problem, as there are currently no data available as to
 whether initiating HAART during the acute presentation is of benefit. Reports of an immune
 reconstitution inflammatory syndrome (IRIS) marked by increasing hypoxia or new pulmonary
 infiltrates have been associated with the initiation of ART in patients with AIDS. There is
 also concern as to drug interactions between ART and antimicrobials used to treat the
 presenting OI. This study will evaluate the possible benefits and costs of initiating ART in
 HIV infected patients who present with an AIDS-defining OI.

 There are 2 steps in this study. In Step 1, patients will be randomly assigned to one of two
 study arms. Arm A will receive ART within 2 weeks of starting therapy for the acute OI. Arm B
 will have ART deferred until Step 2, at least 4 weeks and no more than 32 weeks after
 beginning therapy for the acute OI. Only Arm B participants will enter Step 2, which will
 likely begin between Weeks 6 and 12. The study will make the following drugs available for
 construction of an antiretroviral (ARV) regimen: emtricitabine/tenofovir disoproxil fumarate
 (FTC/TDF), lopinavir/ritonavir (LPV/RTV), and stavudine (d4T). Use of other ARV drugs is at
 the discretion of the study official. Drug regimen additions and substitutions will be made
 on a case-by-case basis.

 Patients will be followed for 48 weeks and will have 10 study visits. All study visits will
 include a physical exam, medication history, and blood collection. Patients will be asked to
 complete questionnaires assessing health status and adherence at selected visits.
Note: Participants who enrolled in this study prior to Version 3.0 will be offered and
 allowed to switch to FTC/TDF if they wish. However, participants under the age of 18 cannot
 receive FTC/TDF through this study.

 Inclusion Criteria for Step 1:

 -  HIV-1 infected

 -  Currently being treated for OI (including Pneumocystis carinii pneumonia [PCP];
 cryptococcal meningitis; disseminated histoplasmosis; disseminated Mycobacterium avium
 complex [MAC]; cytomegalovirus [CMV] retinitis; CMV encephalitis; toxoplasmic
 encephalitis; other atypical non-tuberculous, non-MAC mycobacterial infections; or
 other serious, invasive BIs). 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.

 -  Able to take oral medications

 -  Parent or guardian willing to provide informed consent, if applicable

 -  Willing to use acceptable methods of contraception

 Exclusion Criteria for Step 1:

 -  Any ART within 8 weeks prior to study entry

 -  31 or more days of any ARV within 6 months prior to entry

 -  History of more than one virologic, immunologic, or clinical treatment failure while
 on a HAART regimen, or a history of more than one regimen change for unknown reasons

 -  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

 -  Known resistance to ART that prohibits administration of an effective ART regimen

 -  Current OI has recurred within 90 days prior to study entry. Recurrent BIs are not
 excluded.

 -  Pregnant or breastfeeding
