Q

How to prevent drug resistance?

A
  • ADHERENCE to therapy (taking the drug every day!)

Q

How to prevent HIV transmission?

A
  • SEXUALLY TRANSMITTED: condom use is effective
  • not sexually transmitted when HIV pt is on HIV treatment
  • STI screening and RX
  • sero-adaptive sexual behaviour —-RISK IS MORE IF HE INSERTS
  • disclosure
  • post-exposure prophylaxis
  • pre- exposure prophylaxis
18
Q

Why is STI screening important for HIV prophylaxis?

A
  • HIV -ve pt exposed to STI is VULVNERABLE to HIV
19
Q

Conception options for : HIV+ male, HIV- female

A

(SEX as normal just PrEP for non-HIV pt) Treatment as prevention
(+/- timed condomless sex)
?HIV PrEP for female partner

20
Q

Conception option for

HIV+ female, HIV- male

A

Treatment as prevention
(+/- timed condomless sex)
? Self-insemination
?HIV PrEP for male partner

21
Q

How to prevent Mother to child transmission?

A
  • give PEP for 4 weeks after neonate is born
  • exclusive FORMULA feeding (unknown if breast feeding is infective)
  • if undetected Viral load—–then VAGINAL delivery
  • C-section if otherwise
  • HAART during preg.
22
Q

How effective is it to tell people to abstain?

  • not effective

- does not work

23
Q

BEST HIV strategies at an individual level?

A
  • condom programmes
  • behaviour change interventions (support people to have sex)
  • CONDOM program
  • PEPSE
  • circumcision (reduces HIV risk by 60 % )
  • PrEP
24
Q

Best HIV prevention strategies at a community level?

A
  • needle exchange
  • testing and rx of
    STIs
  • rx as prevention
25
Q
What occurs with blockade of reverse transcriptase? 
What class of retroviral drugs block this?
A

NRTIs (nucleoside reverse transcriptase inhibitors) disrupt the construction of new piece proviral DNA

26
Q

Name 2 NRTIs.

A
  • Lamivudine

- Zidovudine

27
Q

What are the 2 types of entry inhibitors?

A
  1. Fusion

2. CCR5 Receptor

28
Q

What occurs with the blockade of the enzyme protease ?

A
  • HIV uses protease to break down LARGE glycoproteins to use smaller pieces for the assembly of new viral particles.
  • —–virus may still replicate with protease inhibitors but the resulting virions are immature
29
Q

When may dual therapy have little impact on survival?

A
  • when and if the patient was initially on monotherapy and then switched to dual
30
Q

Which HAART medications hold increased risk of MI?

A

Abacavir
Lopinavir
Maraviroc

31
Q

Which HAART med has hematological implication?

A
  • Zidovudine

d/t Anaemia

32
Q

Which medications may result in renal toxicity?

A
  • tenofovir (NRTI)
  • atazanavir (Protease Inhibit.)
    >proximal renal tubulopathies
33
Q

Which HAART drugs result in GI side effects?

A

protease inhibitors (NEVIRAPINE, most others)

34
Q

How may NNRTIs affect drug-drug interactions?

A
  • potent liver enzyme INDUCERS (ALSO the protease inhibitors)

—-therefore acts as pharmalogical boosting for drugs that need it

35
Q

Which BBV has the same treatment as HIV ?

A
