Ans : Changes in the US HIV treatment :
In March 2012, US HIV treatment guidelines were updated and now
recommend initiating antiretroviral therapy, or ART, for all
HIV-infected individuals, regardless of their CD4 cell count.
The new treatment guidelines will positively impact medical care
for people with HIV. Potent combination ART is the standard of care
for HIV infection. Although it cannot eradicate or cure HIV, it can
durably suppress the plasma HIV viral load, which restores and
preserves immunologic function. This can increase longevity and
improve the quality of life for patients living with HIV.
Determining the optimal time to initiate ART has been an evolving
issue. After HIV infection is acquired, there’s typically a
clinically quiescent phase of infection that often lasts five to
seven years, during which many patients will be relatively
asymptomatic.
HIV treatment guidelines have changed because of a growing
awareness that during this clinically quiescent stage, HIV viral
replication persists and causes a gradual destruction of the
individual’s CD4 T lymphocytes. This is associated with
cardiovascular, kidney and liver disease; neurologic complications;
and malignancy. In addition, newer antiretroviral drugs are better
tolerated, more convenient, and more effective than older regimens.
This has reduced both acute and long-term drug toxicities. In
addition, the changes to the guidelines relate to recent studies
that demonstrated that initiating ART early was associated with a
96 percent reduction in HIV transmission.
To increase early diagnosis so that ART can be initiated as soon as
possible, CDC and other medical organizations recommend that health
care providers routinely test patients aged 13 to 64 for HIV.
Diagnosis, however, is only the first step. It is also important
for health care providers to assess each HIV-infected patient they
encounter to determine if they are currently getting routine
medical care and receiving ART.
The 2012 HIV treatment guidelines will undoubtedly impact general
medical practice. Routine HIV screening; ART for all HIV-infected
patients, regardless of their CD4 cell count; and more simplified
and effective antiretroviral regimens will shift more HIV care into
primary car settings. Today, when diagnosed early and ART is
initiated as recommended in the treatment guidelines, HIV can be
treated as a chronic medical ill.
