The purpose of this program is to evaluate an effort to provide a comprehensive package of HIV prevention services of which post-exposure prophylaxis (medicines that may help prevent HIV infection after an exposure) can be a part. It will also include risk reduction information and testing for other sexually transmitted infections.
The Los Angeles County P-QUAD program is a combined effort of County, City, public health, community, academic, and private agencies and individuals in an effort to provide a comprehensive package of HIV prevention services of which PEP can be an integral component. These services are designed to be easily accessible, non-judgmental, culturally, ethnically, and linguistically appropriate to the relevant populations, community-based, and independent of ability to pay or insurance/documentation status. They will also provide vital linkages to associated services, routine HIV testing, and primary health care.

In its initial pilot project, 2 community-based sites will serve as facilities at which patients may present for screening for post-exposure prophylaxis services, as well as sexually transmitted diseases. At the sites, initial eligibility and testing will be performed, and an initial 14-day supply of PEP medications will be provided if appropriate, and referrals will be initiated. All subjects who are provided an initial 14-day supply will be required to return to the site for the remainder of the 28-day course of medication, follow-up testing, adherence counseling, risk-reduction programming, and other appropriate referrals. Follow-up with patients by phone, email, and mobile-phone text message will be used as appropriate to maximize program retention.

Drug tenofovir + emtricitabine, lopinavir/ritonavir

The preferred regimen will be tenofovir + emtricitabine, provided as a fixed-dose combination tablet as Truvada®. Dosing is 1 tablet by mouth once daily. For participants with a creatinine clearance 30-49 mL/min, dosing of Truvada is 1 tablet by mouth every other day. For patients with creatinine clearance <30 mL/min or on hemodialysis, Truvada should not be used. For intolerance to Truvada, Combivir (zidovudine 300mg/lamivudine 150mg)will be available to be taken as 1 PO BID. For highest-risk category exposures (receptive anal intercourse with a known or suspected HIV-positive source patient or in cases of suspected source drug resistance, see Schema, below) one of the following should be added to the above "standard" treatment, creating an "expanded" regimen: Preferred: Lopinavir/ritonavir (200mg/50mg), 2 tablets orally twice daily or 4 tablets once daily

  • Other names: Truvada, Combivir

Open-Label Other

This was an open-label demonstration project. Therefore, medications were not blinded and participants were made aware of the regimen they received for PEP.

Criteria

Inclusion Criteria:

Patients must be at least 18 years of age
Able to understand and provide consent
High-Risk Exposure Characteristic

(one or more of the below, unprotected or with failed condom use)

Receptive Anal Intercourse
Insertive Anal Intercourse
Receptive Vaginal Intercourse
Insertive Vaginal Intercourse

Receptive Oral Intercourse with Intraoral Ejaculation with known HIV+ source (supersedes all "high-risk source" criteria below)

Sharing injection drug works which have been intravascular

High-Risk Source (one or more of the below)

Known HIV positive
MSM
MSM/W
IDU
CSW
Sexual perpetrator
From an endemic country (prevalence >1%)
Partner of one of the above
Exposure within 72 hours of presentation
Not known to be HIV positive
No countermanding concomitant medications or allergies
HIV-negative on presentation and without symptoms of PHI (do not withhold first dose pending these laboratory assessments).

Exclusion Criteria:

Patients <18 years of age
Unable to understand and provide consent
Exposure >72 hours of presentation
Known to be HIV positive
Currently in-progress of a course of PEP initiated via non-P-QUAD mechanisms

Any condition, which in the opinion of the intake provider, will seriously compromise the patient's ability to comply with the protocol, including

adherence to PEP medication dosing
Demonstrated HIV-positive on rapid testing
Unwillingness to commit to barrier-method (male and/or female condom) use until HIV-negative-status is confirmed 6 months after exposure
Unwillingness of breast-feeding women to transition to formula feeding
