2. Objectives
1. To review the principles of HIV
infection and management
2. To emphasize the goals of HIV
screening and counseling during
pregnancy
3. To identify the available resources
in the management of HIV/AIDS in
pregnancy

3. HIV 101
1. HIV is a virus that attacks the
immune system
2. As the viral load increases, the CD4
lymphocyte count decreases.
3. When CD4 count <200 cells,
presence of opportunistic infections
and diseases signal AIDS

14. • New infections are largely
concentrated among key populations
with specific risk behaviors, such as
unprotected male-to-male sex,
transactional sex and intravenous drug
use
• On average, the initiation to sex and
drug use is between 14 and 19 years
old.

HVMADAMBA 2016
15. • Only five per cent of HIV-positive
pregnant women have received
antiretroviral medicines to prevent
mother-to-child transmission.
• Very few of those at-risk have taken an
HIV test, with the number at zero for
those under 18 years.
http://www.unicef.org/philippines/hivaids.html#.V2yW-_l95rQ
HVMADAMBA 2016
17. MODES OF TRANSMISSION
• Unprotected penetrative sexual
contact
• Exchange of infected bodily fluids
• From an infected mother to her
unborn child
HVMADAMBA 2016
18. A total of 81 children (less than 10 years old) and 6 adolescents were reported to
have acquired HIV through mother-to-child transmission
HVMADAMBA 2016
19. The age group of new reported HIV cases is
getting younger!
• 2001 to 2005: 35-49 years
• 2006 to 2010: 25-34 years
• 2011 to 2016: 20-29 years
• Notably, the proportion of
People Living with HIV
(PLHIV) in the 15-24 year
age group increased from
25% in 2006-2010 to 28% in
2011-2016.

22. PREVENTION OF MOTHER TO CHILD
TRANSMISSION OF HIV
• Prong 1. Primary prevention of HIV among women
of child-bearing age.
• Prong 2. Preventing unintended pregnancies
among women living with HIV.
• Prong 3. Preventing HIV transmission among
women living with HIV to her infant.
• Prong 4. Providing treatment, care and support to
women living with HIV, their children and their
families.

Society (Foundation) Inc
Clinical Practice Recommendation on Prevention of
Mother to Child Transmission of HIV Infection
• HIV Screening
• Antiretroviral Drugs
• Management of Delivery
• Infant Feeding
• Contraception
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
24. HIV Screening
Preliminary Counselling Dialogue
Providers of obstetric care should
inform the patient that an HIV
screening test will be performed as
part of the recommended routine
antenatal package of tests of
infections (HBsAg, RPR/VDRL,
rubella IgG, papsmear, urine
culture)
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
25. HIV Screening
Preliminary Counselling Dialogue
• Part of thorough assessment of her status
in relation to her pregnancy
• Routine interview + standard counselling
about HIV
• Strictly confidential
• Opt out - and still receive
the same standard care
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
26. HIV Screening
Preliminary Counselling Dialogue
Key Message:
The fact that you are pregnant is an
evidence of unprotected penetrative
sexual contact which is a mode of
transmission for HIV.
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
27. Post-test Counseling
it takes 3-6 months for
a person to develop
antibodies against HIV
HVMADAMBA 2016
POGS Clinical Practice Recommendations on PMTCT
Pretest counselling informed consent
blood extraction post test counselling
28. Anti-retroviral (ARV) Drugs
• Determine whether patient requires ARV
treatment or just prophylaxis using the
eligibility criteria based on WHO clinical
stage and CD4 cell count.
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
29. Anti-retroviral (ARV) Drugs
Different Clinical Scenarios
1. Woman already receiving ARV
treatment for her own health –
continue.
2. ARV-naïve HIV-infected pregnant
woman with indication for own
health, start ARV regardless of AOG
3. ARV-naïve HIV-infected pregnant
woman, ARV prophylaxis started at
14 weeks AOG
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
30. Anti-retroviral (ARV) Drugs
Eligibility for ARV Prophylaxis
• Option A: maternal AZT + infant ARV
prophylaxis
• Option B: maternal triple ARV prophylaxis
until delivery or if breastfeeding, until 1
week after all exposure to breast milk
ended
• Option B+: start triple ARVs as soon as
diagnosed and continued for life
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
31. Anti-retroviral (ARV) Drugs
Advantages of Option B+
• PMTCT program : simplify
requirements
• Child : extended protection against
mother-to-child transmission
• Partners : prevention benefit against
sexual transmission in sero-
discordant couples
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
32. Anti-retroviral (ARV) Drugs
Advantages of Option B+
• Earlier treatment for woman’s health and
avoiding risks of stopping and starting
triple ARVs especially in settings of high
fertility
• Simple message to communities
“once ARV started, it is
taken for life.”

HVMADAMBA 2016
35. Management of Delivery
• An elective cesarean delivery is
scheduled at 38 weeks AOG
• Emergency CS is done for those in
labor and with ruptured membranes
<4 hours unless delivery is
imminent.
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
36. Management of Delivery
• Vaginal delivery maybe done when
the risk of maternal to child
transmission is low:
– Those who had ARV treatment
– HIV viral load <1000 copies/mL
– If with ruptured membranes, the time
elapsed should be <4 hours to delivery
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
37. Management of Delivery
Essential Intrapartum Newborn Care (EINC)
Thoroughly dry newborn infant
× vigorous suctioning
Skin to skin bonding should be encouraged
× Delayed clamping of umbilical cord is NOT
recommended.
Latching on is done ONLY IF breastfeeding
has been chosen.
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
38. Infant Feeding
Avoid breastfeeding in women you
are HIV positive.
Even when no breastfeeding is the
chosen strategy, explain to the HIV+
mother the importance of continuing
the ARVs prescribed for her and her
infant.
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
39. Infant Feeding
• avoid breastfeeding, danger of mixed feeding
• continuing ARV medications
• replacement feeding: acceptable,
feasible, affordable, sustainable
and safe (AFASS)
• risks, follow up and other options for
replacement feeding
• relieve breast engorgement
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
40. Contraception
• Best protection obtained by:
– Choosing sexual activities that do not allow
semen, fluid from the vagina, or blood to
enter the mouth, vagina or anus of the
partner
– Correct and consistent use of condoms
during every sexual act
– Reducing the number of partners
POGS Clinical Practice Recommendations on PMTCT
HVMADAMBA 2016
41. Prevention of HIV Infection of
Health Care Workers
• Standard precautions
• Post-exposure prophylaxis
• Hospital infection control

Notas del editor
During the past decade, many national epidemics have changed dramatically.
In 39 countries, the incidence of HIV infection among adults fell by more than 25% from 2001 to 2011
Epidemiological trends are less favourable in several other countries. In at least nine countries including the PHilippines, the number of people newly infected in 2011 was at least 25% higher than in 2001.
Locally, the incidence is dramatically increasing in our country. The Philippines is marked in red.
A post-test counselling should be done by the healthcare provider once the HIV screening test result is known. 4
If the test is negative: recommend a repeat test 3-6 months later to account for the window period;
Counsel the patient and her partner to maintain a healthy lifestyle, including a low-risk sexual relationship
