Meet
the Expert
David Cooper, Director, National Centre
for HIV Epidemiology and Clinical Research, Australia
Dr Cooper presented the ideological scenario
that should be the gold standard of treatment and care
for all nations. The paradigm is to drive viral load
to the limit of detection. Mono and dual therapy produce
only transient responses, resulting in sub-optimal viral
inhibition and creating an environment, which encourages
viral resistance development. Therefore triple therapy
has to be the gold standard for all. However, there
are powerful arguments for dual and even mono therapy
in resource-poor settings. Dual therapy, though not
optimal, results in a 60 percent decrease in mortality
and is a fifth of the cost of triple therapy, but pricing
changes may negate this difference. Because of late
presentation and diagnosis, many cases are terminal
and any intervention which improves quality of life
and extends life, if only slightly, is beneficial. HIV
transmission and drug resistance are not issues with
these people. Dual therapy is widely used in India,
Thailand and Malaysia. Doctors have a duty of care for
their patients and where triple therapy is unaffordable
dual therapy, when used wisely, is better than nothing.
An economic disadvantage of dual therapy is that it
may send the wrong message to governments.
