TREAT Asia (Therapeutics Research, Education, and AIDS Training in Asia)
Collaborative network of
1) Clinics
2) Hospitals,
3) Research institutions,
4) Civil society
to ensure the safe and effective delivery of HIV treatments to adults
and children across the Asia-Pacific through research, education, and
advocacy of evidence-based HIV-related policies. TREAT Asia’s unique
capacity to bring together researchers, doctors, activists, advocates,
and policymakers plays an important role in the region’s response to
HIV, and it has become a model for regional collaboration on HIV/AIDS.


Evidence for initiating antiretroviral therapy (ART) at
CD4+ counts >350 cells/mm3 primarily comes from large
cohort studies for which the findings have not been
consistent.

There is uncertainty about the effects of early ART on
serious non-AIDS conditions.

Most of the morbidity at high CD4+ counts is due to nonAIDS conditions.

The absolute risk of AIDS is low at higher CD4+ counts,
thus the adverse effects of early ART could easily
outweigh the benefits of reducing the risk of AIDS.

 Number of death by any causes is lower in
Imm. ART arm (12) compared to Def. ART arm
(21)
 Event of all type of cancer is lower in Imm.
ART arm (14) compared to Def. ART arm (39)
 Bacterial infectious disorder is lower in imm.
ART arm (HR=0.38, p = 0.002)
16

Combination antiretroviral therapy (ART) should
be recommended for all HIV-positive persons
regardless of CD4+ count.

The START Study results align the benefits of ART
to the HIV-positive individual to the benefits of
ART to reducing the risk of viral transmission from
HIV-positive persons to non-HIV-infected
individuals.

HIV & Aging is a Critical Need to Re-engage
 Optimal models of Care for HIV elders
 Manage the syndromes associated with aging in HIV
elders
 Understanding social networks, safety nets, support
networks
 Improving the quality of life for patients unlikely to be
eligible for cure strategies in the next decade

On-Treatment Patients (active follow up) : Virological
Suppression rate is >80% up to 5 years after ART
initiation.
Intention-to-treat Patients (included died, stopped
ART and LTFU) : Virological Suppression rate
declined from 75% (6mths)
to 62% after 4 years.
30
31
1) High rates of OT virolocigal suppression probably due to
• Analysis limited on individuals on ART retained in care
• Spontaneous viral suppression
• Impact of adherence
2) ITT analysis:
Numbers of patients died, LTFU or stopped therapy
Virological failure did not observed probably because of
dropped out from care before can be identified or very little
switched to secondline regime.

population and bring
them into HIV
prevention and care
High CD4 do not want to
start HAART. Probably poor
adherence and causing the
spread of resistance
Only professional can
provides HIV testing and
giving counselling about
ARVs.

1) 400mg EFV remains virologically non-inferior to the standard 600mg.
 Rates of viral suppression is similar in both arms.
2) Overall frequency and severity of adverse events do not reduced.
 Most events mild to moderate
 Significantly EFV-related adverse events (included CNS AE) is higher in 600mg
dose.
 Fewer people discontinue treatment in 400mg dose arm.
 However, does not effecting DASS-21 score (Depression and Anxiety).
3) Applicable to healthy adult, further investigation needed for adolescents and
malnourished patients.
4) Wide practices of reduced-dose EFV would reduce the drug costs especially middle

and low-income country.
