Q

What is the importance of prevention of mother-to-child transmission (PMTCT) programs?

A

Without PMTCT programs, 1 in 3 babies born to HIV-positive mothers will become HIV-positive. With single-dose Nevirapine during delivery, this risk decreases to 1 in 10. With antiretroviral therapy (ART) for mothers and post-exposure prophylaxis (PEP) for babies, the risk further decreases to 1 in 100.

Q

For breastfeeding infants on high-risk prophylaxis: If maternal viral load is not suppressed by 12 weeks, continue NVP prophylaxis until maternal VL is ________, or until 1 week after breastfeeding stops

A

<1000c/ml

22
Q

What age group of adolescents needs urgent intervention for the prevention of new HIV infections, particularly among girls?

A

Adolescents aged 15-19 years old, especially girls, require urgent intervention due to high transmission rates and disempowerment in negotiating condom use.

23
Q

What are some recommended interventions for preventing new HIV infections in adolescents?

A

Recommended interventions include talking to children about sex and consent, voluntary male circumcision, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), access to secondary and higher education, and integration of sexual and reproductive services with HIV services for young people.

24
Q

Why are 15-19-year-old girls particularly vulnerable to HIV infection?

A

15-19-year-old girls are particularly vulnerable due to high transmission rates and challenges in negotiating condom use, often stemming from social and gender-related factors that disempower them.

25
Q

What is PrEP and how does it help in preventing HIV infections?

A

PrEP stands for pre-exposure prophylaxis, which involves taking antiretroviral medication regularly to prevent HIV infection in individuals who are at high risk. It provides an additional layer of protection against HIV transmission.

26
Q

How can the integration of sexual and reproductive health services with HIV services benefit young people?

A

Integrating sexual and reproductive health services with HIV services ensures that young people have comprehensive access to prevention, testing, and treatment services in one location, which can improve uptake and effectiveness of interventions.

27
Q

Define AIDs free:

A

Ensure ART access to 95% of HIV infected children

28
Q

Why do foetuses and newborns typically experience more rapid and extensive HIV replication compared to older hosts?

A

Foetuses and newborns have immature immune systems, leading to more rapid and extensive HIV replication. Consequently, there is a more rapid disease progression in children, with approximately 50% of HIV-positive children expected to die within two years without antiretroviral therapy (ART).

29
Q

How do viral loads in HIV-positive children change as they age?

A

Viral loads are higher in the first year of life and then decline to adult values by 5-6 years of age.

30
Q

What is the significance of CD4 counts in infants compared to older children and adults?

A

Absolute CD4 counts are much higher in infancy, with counts exceeding 3000 cells/mm³.

31
Q

How does the CD4 percentage change in children with HIV, and what does it correlate with?

A

The CD4 percentage remains constant in children and correlates with disease progression, serving as an important marker for monitoring HIV progression and treatment response.

32
Q

What are some strategies used to ensure access to ARTs?

A

 Diagnose ASAP (highest mortality between 6 weeks and 4 months)

 Early diagnosis and treatment decreases risk of HIV encephalopathy and opportunistic infections

 Treatment must be effective, well tolerated, simple and universal

 Adults have 1 big tablet to take once a day but children have multiple syrups (some are bad tasting) and
vitamins that need to take bidaily – this is unfair. Additional TB medication is even worse

33
Q

Cher study – when to start ART?

A
  • Diagnosis and tx before 3 months of age showed much better outcomes (decreases mortality and developmental delay)

Q

National ART regimens:

A

Dolutegravir (DTG) if > 20kg

39
Q

Psychosocial criteria to start child on ART:

Mandatory:

A

At least one identifiable caregiver who is able to supervise child or administer medication

40
Q

Psychosocial criteria to start child on ART:

Recommended:

A

Disclosure to another adult living in the same house is encouraged so that there is someone else who can assist with the child’s ART

41
Q

Criteria for fast-tracking for ART:

A
42
Q

Is disclosure of HIV status a one-time event?

A

No, disclosure of HIV status is an ongoing process, not a one-time event.

43
Q

At what age should HIV status be properly explained to children?

A

HIV status should be properly explained to children at 8-9 years old, and the topic should be revisited at every visit thereafter.

44
Q

At what age do individuals have a legal right to know their HIV status?

A

Individuals have a legal right to know their HIV status at 12 years of age.

45
Q

Who ideally should disclose HIV status to children?

A

Ideally, HIV status should be disclosed by caregivers, such as parents or guardians.

46
Q

How does disclosure of HIV status contribute to improved health outcomes?

A

Disclosure of HIV status improves adherence to treatment and mental health, as it is the number one predictor of poor adherence.

47
Q

What are the pharmaceutical Challenges for Paediatric ART? (5)

A
48
Q

How many children globally are in need of antiretroviral treatment (ART), and what percentage are on a suboptimal regimen?

A

Globally, 2.1 million children are in need of ART, with 40% of them on a suboptimal regimen.

49
Q

What is a common concern regarding the available formulations for paediatric ART?

A

A common concern is that there is “too much of what we don’t need,” indicating that the current formulations may not adequately meet the needs of children living with HIV.

Q

Care of the HIV-exposed but Uninfected (HEU) infant
