with distinction between right and wrong –
the moral consequences of human action
• The ethical principles in epidemiological
practice and research includes:
– informed consent

– Respect for human rights and
– Scientific integrity

7. Why is ethics important?
• Required for human life
• Means of deciding on a course of action
• Without ethics – no way to work towards goal

8. General ethical principles
• Respect for person
– Autonomy
– Protection of persons with impaired or diminished
autonomy

9. Ethical Dimension of HIV/AIDS
1. Clinical Ethics
Monday, March 11, 2013 Ethical dimensions of HIV/AIDS 9
10. Confidentiality
• Protection of HIV related medical records
• Exceptions may exist (e.g. HIV/AIDS cases
should be reported to Public Health
Authorities in USA)
– Benefits to public health to outweigh the risk to
individuals
– Health care providers may also disclose a patient’s
HIV infection to person at risk of infection
• Prevent serious harm to an identifiable person
• No other effective means of achieving goal
• The breach of confidentiality is minimized

11. Informed consent for testing
• Blood test do not require extensive informed
consent discussion (minimal risk, only implied
consent)
• However, in early epidemics of HIV/AIDS
– Serious psychosocial risks (e.g. rejection by
family, discrimination in employment)
– Specific procedures (e.g. pretest
counseling, specific informed consent)
Monday, March 11, 2013 Ethical dimensions of HIV/AIDS 11
12. Exceptions to informed consent
• HIV test without consent
– Significant exposure to emergency response
workers or health workers
– Testing of prisoners
– Persons accused of sex crimes
– Mandatory HIV testing of newborns (indirectly
reveals maternal HIV status)
Monday, March 11, 2013 Ethical dimensions of HIV/AIDS 12
13. Exceptions to informed consent
• Prenatal HIV testing (all pregnant women be tested
for HIV as a routine part of prenatal care in US)
• May raise several concerns
– Acceptability
– Women may not realize that they have option to
decline testing
– Caregivers may forget the psychosocial risk of
testing
– Routine testing may undermine prevention efforts
– May affect adherence to the norms of pretest
counseling and informed consent in other contexts

14. End of life issues
• End-of-life care in HIV infection in US has
become less prominent – as the availability of
highly active antiretroviral therapy prolonged
survival
• In developing countries palliative care focuses
on relief from suffering (pain, psychosocial
issues)
– Ongoing efforts to reduce the price of
ARV, permitting production of generic
version, provisions of funds

15. Ethical Dimension of HIV/AIDS
2. Research Ethics
Monday, March 11, 2013 Ethical dimensions of HIV/AIDS 15
16. General principles
• Helsinki Declaration of1964 focuses on:
– Privacy and integrity of individuals protected
– Adequate informed consent
– Research for valid scientific benefits
– Accepted scientific principles
– Benefits outweigh risks
– Protect control group
– Individual wellbeing vs. needs of science and
society
Monday, March 11, 2013 Ethical dimensions of HIV/AIDS 16
17. Research design
• People accept risks and inconvenience to
advance knowledge and to benefits others
• Sufficiently rigorous that the results will be
valid and generalizable
• Meet ethical obligations
• Adequate sample size
• Appropriate end point (study outcome)
• RCTs – require preliminary lab and animal
research
Monday, March 11, 2013 Ethical dimensions of HIV/AIDS 17
18. Informed consent
• Informed consent might be affected by
– Personal expectation
– Individual benefits vs. generalizable knowledge
– Inadequate understanding of experiment vs. research
– Randomization
– Patients inclination to follow the advice of their health
care providers
– Patients trust in health care providers
– Over estimation of the benefits by health care
providers

19. Vulnerable participants
• Vulnerability is defined by categories, in US
includes:
– Children, prisoners, pregnant women, mentally
disabled person, economically and educationally
disadvantage persons, homosexuals, injecting
drug users, minorities
• Vulnerable groups require special protection
from research risks

20. Conflict of interest
• Some conflicting interest are inherent in research
such as:
– Gain prestige, grants, promotion, publication
– This interest may conflict sometimes with the best
interest of participants
– It is an accepted element of research and
acknowledged
• Some interest e.g. financial interest may create
ethical problems
– Overestimate the benefits, underestimate the risks

21. Special issues in vaccine research
• Good animal model does not exist
• HIV is highly variable and undergoes rapid
mutation
• Little information on protection against HIV
• Misbelieve of protection from the vaccine, may
increase high risk behavior
• Participants should have access to appropriate
risk reduction counseling
• Appropriate monitoring
Monday, March 11, 2013 Ethical dimensions of HIV/AIDS 21
22. Special issues in vaccine research
cont…
• Risk to participants
– May not participate in future trials, less effectiveness
of vaccine may produced in the future
– Positive reaction to HIV antibody tests (may limit
travels and eligibility for certain jobs)
• Early phase clinical trials should take place in
sponsor countries
• Placebo-controlled vaccine trials are ethically
acceptable

26. Conclusion
• Muslim Physician and the ethics of medicine:
the Muslim physician, guided by Qur’an and
Sunna (two primary sources of Islamic
Law), will possess the necessary character
traits of a good physician. This in turn, will
lead to a healthy physician-patient
relationship and will safeguard the profession
of medicine.

2nd Exception – HIV Positive Health Care Providers – who perform exposure-prone invasive procedures (expert review – may required to inform patients about their HIV status)
In majority of stats still specific procedures are in place for testing – counseling, nature of the test, risk and benefits, prevention of transmission, confidentiality of the results, voluntary nature of the test, availability of anonymous testing
Situation is different in developing countries – high cost of ART (prophylaxis) – may help in inform decision e.g. breastfeeding – may expose women to physical harm, loss of job and housing
