    Study Notes

    Southern African Guidelines on PrEP: 2020

    • PrEP (pre-exposure prophylaxis) with antiretroviral agents is a standard HIV prevention method
    • Oral PrEP is safe and effective for preventing HIV transmission through sexual or other means
    • PrEP use in Southern Africa is currently low and needs improvement
    • Updated 2020 guidelines aim for broader PrEP access
    • Eligibility expanded to include pregnant and breastfeeding women
    • Streamlined PrEP initiation and administration (same-day PrEP)
    • On-demand PrEP now included for MSM and TG women
    • Updated adverse event and drug interaction information
    • Parameters to measure PrEP rollout effectiveness are suggested

    Background

    • First Southern African HIV Clinicians Society guidelines published in 2012
    • Guidelines based on three clinical trials: iPrEx, Partners PrEP, and TDF2
    • Since 2012, further trials and studies confirmed the efficacy of combination therapies (e.g., tenofovir and emtricitabine) for HIV prevention
    • WHO target of 3 million PrEP users worldwide by 2020
    • South Africa faces high HIV incidence (15% of global new infections) despite estimated 45,000 people on PrEP in June 2020

    Quick Facts on Oral PrEP

    • PrEP involves daily use of TDF or TAF/FTC, TDF/FTC co-formulated or variants
    • Most used and licensed for oral PrEP is TDF/FTC
    • PrEP is shown to effectively prevent HIV transmission from heterosexual and drug use relationships
    • Consistent PrEP adherence yields over 95% protection
    • Daily use ensures optimal efficacy
    • Condoms are still recommended for STI prevention
    • PrEP has no contraceptive effect
    • PrEP is safe during pregnancy and breastfeeding

    When PrEP Should Not Be Offered

    • Confirmed or suspected HIV-positive individuals
    • HIV seroconversion is suboptimal time for PrEP implementation
    • Acute viral illness individuals (suspect HIV seroconversion)
    • Pre-existing significant renal dysfunction (eGFR <50 mL/min)
    • Individuals with significant weight (<35 kg)

    Simplifying PrEP Use

    • Ensure PrEP users understand the intervention and have a personal plan
    • PrEP users must be HIV-negative (rapid test acceptable)
    • The PrEP suitability and safety is assessed before initiating the treatment, including renal function evaluation and assessing other possible contraindications
    • Step-by-step clinical consultations with PrEP users
    • STI screening recommended at initiation, and 6-monthly for key populations
    • Hepatitis B screening and vaccination, if indicated or status unknown
    • Renal function baseline screening (creatinine and eGFR) for patients over 40 or with co-morbidities

    Considerations for Pre-Exposure Prophylaxis

    • On-demand PrEP is offered to MSM and TG women in two pills before potential sex, with another pill followed for two days after the encounter
    • The frequency of PrEP dosing varies based on potential exposure risk, vaginal or anal mucosa, and if HIV exposure is occurring.
    • If PrEP user's risk level changes, continuation or cessation is recommended, guided by potential exposure risks
    • PrEP use should be offered as part of a comprehensive package focused on STI prevention, contraception, and general sexual and reproductive health, with explicit consent

    Updates to Adverse Events and Drug-Drug Interactions

    • TDF/TAF are generally safe and well-tolerated
    • Minor side effects (headache/GI upset) are common in 10% of patients and resolve naturally
    • Some degree of renal reduction in CrCl might occur in the first few months of initiating
    • Renal function monitoring is recommended for PrEP users, especially pregnant women, aged >40 or with underlying conditions.
    • Tenofovir-based PrEP needs to be taken with caution in individuals with pre-existing renal issues, since it can impact renal function.
    • For patients with reduced bone mass or other relevant risk factors, TAF or episodic TDF is suggested as an alternative
    • Hepatitis B screening is recommended before initiating PrEP but does not prevent it.
    • Drug interactions are manageable; Tenofovir (TDF) needs to be used with caution for drugs causing renal toxicity

    Conclusion

    • PrEP guidelines will be adapted with ongoing research and clinical trials
    • Wider PrEP uptake (in different modalities) is critical for HIV preventative efforts
