Two diseases, one patient…
Tuberculosis (TB) and Human Immunodeficiency Virus (HIV) – can we continue to tackle these separately? According to the Global TB Report (2012), in 2011, out of 8.7 million people who developed TB worldwide 1.1 million (13%) were HIV positive. An approximate of 0.4 million HIV-associated TB deaths took place in 2011 and TB is the most common opportunistic infection among people living with HIV (PLWH). HIV increases chances that latent TB infection can become active TB disease and also increases the risk of death due to this.
While all of us know the individual effect of each of these
diseases and the challenges faced by the patient to get
diagnosed, endure the treatment and side effects, it is
difficult to even begin to realize the interactions of the drugs
and the complexities of these two diseases that many a patient
is in. Having HIV with TB, or TB with HIV then means too many
drugs for a very long time and the need for constant monitoring
and compliance. More the drugs, more the side effects and
struggle to keep it going. While one takes these drugs to be
alive despite all odds, damage is done to the liver and kidneys
among other organs. Socially, the patient endures a double
stigma: the taboo along with the isolation. If one thinks this
is enough on the list for a lifetime, the list isn’t
finished yet.
A day in the life of TB-HIV patient involves travelling long
distances to be seen by a doctor for a little more than 30
seconds, being pushed from one facility to another, from one
long queue to another longer one in order to get a test done, a
packet of drugs or the next bus home. Given their current body
strength, they have to keep to this system of medical services
to find out, very often with much delay, that they have managed
to get two very big diseases. The delay is due to logistics, no
co-ordination between doctors and their documentation, or
defaulters. The individual loss of the day’s work, energy,
meals, coupled with an accompanying caretaker’s loss of
day’s work only adds on to the overall situation. A woman
who also needs to manage her home, children and job is left to
wait for hours in a facility which, at the end of the day, will
inevitably send her to another site for further management.
The potential threat of disease doesn’t remain with the
patient but spreads to society as these patients travel in
crowded transportation from one place to the other. “There
are 3 main measures that can be implemented”, according to
Dr Valerie Schwoebel, from the
International Union Against Tuberculosis and Lung Disease
(The Union). “They are called “the three I’s:
Infection control, Intensified case-finding and Isoniazid
preventive therapy. Infection control consists in taking
precautions in order to reduce the transmission of the tubercle
bacilli, which are disseminated in air by TB coughing patients.
This includes diagnosing and treating TB early in the family and
contacts of the HIV-infected person, implementing airborne
infection control measures at health facilities. Intensified
case-finding means that searching for TB should be always part
of the medical follow-up of people living with HIV: health
workers should always be on the alert for TB at all times and TB
diagnostic and treatment services should be easily available and
accessible. Isonazid preventive therapy is a treatment that can
prevent the development of active TB disease in PLWH already
infected by the bacilli but not yet sick. The treatment
lasts at least 6 months and must be delivered in settings where
careful evaluation and follow-up of patients is organized.
Presently, we see divided management in both government and
private health systems who have taken up TB or HIV management
and care around the world. Vertical national TB and HIV
programs, both recognize the need for early detection of
diseases in their respective cohort. However, not much has been
done so far to facilitate that. Many doctors still do not follow
the mandatory testing of TB and HIV in respective diseases, but
only test TB patients for HIV, when in doubt of the same. While
some organisations focus on TB treatment close to areas of low
socio economic populations, others focus on HIV in areas like
targeted intervention among commercial sex workers, truck
drivers, the MSM community and IV drug users.
While many programs are still weighing out and arguing the
benefits of the same, some integration programs internationally
and in India, have shown to be successful and possible to save
many lives. Dr. Paula Fujiwara, Scientific Director at the
International Union Against Tuberculosis and Lung Disease
(The Union) shares the organisation’s extensive experience
in this. “Key issues required to scale up collaborative
activities include: 1. Commitment and ownership at national
level by BOTH the TB and HIV programs to integrate services.
2. At the level where services are provided, linking and
integrating the needs of the dually-affected person” she
shares.
Swaziland has one of the highest incidences of TB in the world
and one of the highest prevalence of HIV. COMDIS, a research
programme consortium that works to drive research and
development to combat communicable diseases in low-income
countries works here. COMDIS supported the rural hospital Good
Shepherd Hospital to introduce HIV testing by TB nurses. They
implemented the ‘3 Is’ for people living with
HIV/AIDS. The national program soon followed suit. International
HIV/AIDS Alliance, in its projects, links TB and HIV by
increasing awareness of TB/HIV and educating patients and
counseling them on TB infection control measures. TB case
detection among people with HIV and HIV testing of TB patients
is carried out.
Adherence support for both TB and HIV patients is done. Closer
to home, the state of Karnataka began integrative services
following the model put forth by Samastha project funded by
USAID and Karnataka State AIDS Prevention Society (KSAPS). This
requires training of district project officer, nurses, and other
caretakers to make sure that quality management is given to the
patients. Although assessments done show that collaboration
between the two programs is relatively inexpensive, the
investments lie in reducing the gaps in knowledge and skills
among health workers, laboratory diagnostics, staffing levels,
medical supplies and infrastructure.
In order to combat these two public health problems there has to
be a sustained effort in strengthening and integrate the health
system to provide quality health care. In March 2012, World
Health Organisation (WHO) made some recommendation towards
TB-HIV collaborative activities. The recommendations included:
A.) To establish and strengthen the mechanism for delivering and
integrating TB and HIV services, B.) To reduce the burden of TB
in people living with HIV and initiate early ART by the three
Is. C.) Reduce the burden of HIV in patients with presumptive
and diagnosed TB. The question remains, as Dr. Michel Sidibe,
UNAIDS Executive Director asked at the Stop TB Partner’s
Forum in 2009, “When a virus (HIV) and a bacteria (TB) can
work so well together, why can’t we”?
