When to Start
I A S - U S A R E C O M M E N D AT I O N S 2 0 1 4
Günthard et al, JAMA, 2014.
When to Start ART:
IAS-USA Recommendations 2014
ART is recommended for treatment of HIV infection and
prevention of transmission of HIV regardless of CD4 cell
count (AIa-BIII)
 Lack of demonstrated harm with early initiation, cost
effective, clinically beneficial
 ART is cost-effective in resource-rich and –poor countries
 In next 4 years, more than 20 drugs are expected to
become available as generics
Slide 8 of 41
Günthard et al, JAMA, 2014.
When to Start ART:
IAS-USA Recommendations 2014
Offer ART to all patients with acute or early infection; start
as soon as possible to maximize benefit
 Reduced proviral DNA and plasma viral load, lower viral
set point, robust immune reconstitution, and CD4 cell
counts greater than 900/µL
 Planned discontinuation after specific duration is not
recommended except in research settings
Slide 9 of 41
Günthard et al, JAMA, 2014.
When to Start ART:
IAS-USA Recommendations 2014
 ART is recommended regardless of CD4 cell count
 The patient must be willing and ready to initiate
therapy; patients not ready to start ART should
remain in clinical care, with regular monitoring and
ongoing discussion about need for ART
 The strength of recommendations and evidence
increase as CD4 cell counts decrease and in the
presence of certain conditions
Slide 10 of 41

When to Start ART:
IAS-USA Recommendations 2014
Strength of recommendation and quality of evidence
varies
 According to CD4 cell count:


CD4 cell counts <500 µL(AIa)
CD4 cell counts of >500 µL (BIII)
 According to clinical condition with CD4 cell counts of
>500 µL:



Pregnancy (AIa)
Chronic HBV co-infection (AIIa)
HIV-associated nephropathy (AIIa)
Slide 11 of 41
Günthard et al, JAMA, 2014.
When to Start ART:
IAS-USA Recommendations 2014
 According to clinical condition (cont’d):
 Acute
phase of primary HIV infection, regardless of
symptoms (BIII)
 Preferably within first 2 weeks of diagnosis of
opportunistic infections (AIa)
 Early in treatment for cryptococcal meningitis, when
expert management of both HIV and cryptococcal
infection is available (BIII)

What Treatment to Start
I A S - U S A R E C O M M E N D AT I O N S 2 0 1 4
Günthard et al, JAMA, 2014.
What Treatment to Start:
IAS-USA Recommendations 2014
 ART is considered lifelong; sustained viral suppression
is foundation for immune recovery, optimal health, and
prevention of resistance and transmission.
 Maximize adherence and minimize toxicity: Goal is to
treat with effective, well-tolerated therapy, with limited
drug interactions and effects on comorbid conditions.
 Base selection on baseline resistance testing and
patient characteristics and preferences

Both medications taken twice daily;
single study with relatively small
sample size and low baseline
plasma HIV-1 RNA level.
Recommendations for Initial Treatment in
the Settings of Specific Conditions
 Pregnancy: ART should be initiated in all HIV-infected
women who become pregnant; ZDV/3TC plus either
RTV-boosted LPV or RTV-boosted ATV are preferred.
 Comorbid diseases: Choice of regimen is influenced by
chronic and acute comorbidities; assess for
exacerbation of comorbid conditions, negative clinical
outcomes, increased ARV toxicity, drug interactions with
ARV agents.
Slide 22 of 41
Günthard et al, JAMA, 2014.
Recommendations for Initial Treatment in
the Settings of Specific Conditions, cont’d.
 In patients with or at high risk of cardiovascular disease,
avoiding use of ABC, RTV-boosted LPV, or RTVboosted Fos-APV might be considered.
 In patients with reduced renal function, TDF should be
avoided, especially in combination with a boosted PI.
 Given the increased risk of fragility fractures, it may be
prudent to avoid TDF as part of initial therapy in
postmenopausal women.
Slide 23 of 41
Günthard et al, JAMA, 2014.
Recommendations for Initial Treatment in
the Settings of Specific Conditions, cont’d.
 The recommended initial ART regimen in the setting of
rifampinbased TB treatment is 600 mg EFV plus 2 NRTIs; if EFV
cannot be used, rifabutin-based therapy with a boosted PI plus 2
NRTIs is an alternative.
 A 3-month, once-weekly regimen of isoniazid with rifapentine for
treatment of latent TB infection is as effective as 9 months of
isoniazid alone and is equally effective in HIV-infected individuals.
 No data yet on use of bedaquiline for treatment of multidrugresistant TB in HIV-infected patients receiving ART; expert
consultation is recommended.
Slide 24 of 41
Günthard et al, JAMA, 2014.
Recommendations for Initial Treatment in
the Settings of Specific Conditions, cont’d.
 The ART regimen for HIV- and HBVcoinfected persons should
include TDF and FTC or 3TC as the NRTI background.
 DTG- or RAL-based regimens are recommended for patients
receiving anticancer or immunosuppressive drugs.
 In the setting of HCV and HIV co-infection, consult guidance from
the AASLD, IDSA, or IAS-USA.

Monitoring
I A S - U S A R E C O M M E N D AT I O N S 2 0 1 4
Günthard et al, JAMA, 2014.
Recommendations for Monitoring Upon
Initiation of or Change in ART
HIV-1 RNA levels:
 Monitor at approximately 4 weeks after treatment initiation
or change;
 Monitor every 3 months to confirm suppression of viremia to
below the limitation of quantification of sensitive commercial
assays (AIa).
CD4 cell count:
 Monitor every 3 months after initiation of ART, especially for
patients with cell counts of <200 µL;
 results will determine need to initiate or discontinue primary
opportunistic infection prophylaxis (BIII)
Slide 27 of 41
Günthard et al, JAMA, 2014.
Recommendations for Ongoing Monitoring
 Monitor at intervals of ≤6 months if viral load is suppressed for 1
year, CD4 cell count is stable at ≥350 µL, and patient’s adherence
is dependable (CIII).
 Monitoring is optional if viral load is suppressed consistently for
more than 2 years, CD4 cell counts are persistently >500/µL,
except in setting of virologic failure or immunosuppressive
treatments or conditions (CIII).
 If HIV-1 RNA level is detectable (>50 copies/mL) during therapy,
confirm within 4 weeks before making changes (BIII).
 If HIV-1 RNA level is greater than 200 copies/mL during therapy,
evaluate factors leading to failure and consider switch in ART
(AIIa).
Slide 28 of 41
Günthard et al, JAMA, 2014.
Recommendations for Ongoing Monitoring, cont’d.
 Perform baseline genotypic testing for resistance in all
treatment-naive patients (AIIa) and in cases of confirmed
virologic failure (AIa).
 Routine therapeutic drug monitoring is not recommended,
though selected patients may benefit (BIII).
 Laboratory monitoring for ART toxicity is recommended,
guided by presence or absence of comorbidities and by
components of the regimen.

Changing ART Regimens
I A S - U S A R E C O M M E N D AT I O N S 2 0 1 4
Günthard et al, JAMA, 2014.
Recommendations for Changing the ART
Regimen in Treatment-Experienced Patients
 Design of a new regimen should consider previous ART
exposure, previous resistance profile, and history of
intolerance or toxic effects (AIIa).
 Depending on the resistance profile, viral tropism, and
options available for patients with multidrug resistance,
inclusion of a boosted PI and agents from newer drug
classes (eg, an INSTI or maraviroc) should be considered
(AIa).
 Monotherapy with a boosted PI is not recommended when
other options are available (AIa).
Slide 31 of 41
Günthard et al, JAMA, 2014.
Recommendations for Changing the ART Regimen
in Treatment-Experienced Patients, cont’d.
 Maintenance of virologic suppression is paramount when
switching the regimen to improve tolerability, reduce toxicity,
and improve convenience (AIa).
 Switching or regimen simplification in virologically
suppressed individuals is generally safe if prior treatment
and resistance profile are considered. Full activity of the
NRTIs is important when switching from a RTV-boosted to a
drug with a lower barrier to resistance (AIa).

factors leading to failure and consideration of switching ART
(AIIa).
 Laboratory monitoring for ART toxicity is recommended. In the
absence of new abnormalities after week 16 of treatment, the
frequency of monitoring—generally between 3–6 months—should
be guided by the presence or absence of comorbidities and by
the components of the regimen (CIII).

Conclusions
I A S - U S A R E C O M M E N D AT I O N S 2 0 1 4
Günthard et al, JAMA, 2014.
Conclusions
 Early, intensified, widespread, and uninterrupted treatment is
best option for controlling the epidemic.
 To exploit full potential of ART, greater efforts are needed to
diagnose and treat infection as early as possible, and
particularly acute and recent infection, which is a major
driver of the epidemic.
 New, less toxic drugs with convenient dosing facilitates
widespread acceptance of early ART.
 New strategies are needed to reduce stigmatization and
discrimination that delay care.
