Q

How to support mental health in woman with HIV

A

Antenatal HIV care should be delivered by a multidisciplinary team (MDT).

We recommend that pregnant women living with HIV are offered peer support where available.

Assessment of antenatal and postnatal depression should be undertaken at booking, and 4–6
weeks postpartum and 3–4 months postpartum in accordance with National Institute for Care
and Health Excellence (NICE) guidelines.

Q

What do you before starting treatment?

A

HIV resistance testing should be completed and results available prior to initiation of treatment, except for late-presenting women (after 28 weeks).

Women should be encouraged to continue combination (c)ART post-delivery but, where they chose to stop cART, a further resistance test
is recommended to ensure that mutations are not missed with reversion during the offtreatment period

Q

When starting treatment what other tests are needed? How do you monitor treatment effect?

A

In women conceiving on cART there should be a minimum of one CD4 cell count at baseline and
one at delivery

In women who commence cART in pregnancy, a CD4 cell count should be performed as per
routine initiation of cART with the addition of a CD4 count at delivery even if starting at CD4
>350 cells/mm3

In women who commence cART in pregnancy,
an HIV viral load +
LFTs should be performed 2–4 weeks after commencing cART, at least once every trimester, at 36 weeks and at delivery.

Q

If a woman on cART viral load is not suppress what do you need to consider

A

In the event that a woman who has initiated cART during pregnancy has not suppressed plasma
viral load to <50 HIV RNA copies/mL, the following interventions are recommended:

  • Review adherence (including a full exploration of potential impacting factors) and concomitant medication;
  • Perform resistance test if appropriate;
  • Consider therapeutic drug monitoring (TDM);
  • Optimise to best regimen;
  • Consider intensification.

Q

If already on ART - is it safe to conceive on?

Any exceptions?

A

It is recommended that women conceiving on an effective cART regimen should continue this
treatment

Exceptions are:
• Non-standard regimens, for example protease inhibitor (PI) monotherapy;
• Regimens that have been demonstrated to show lower pharmacokinetics in pregnancy such
as darunavir/cobicistat and elvitegravir/cobicistat, or where there is an absence of
pharmacokinetic data such as for raltegravir 1200 mg once daily (od) (should be administered 400 mg twice daily [bd]). These should be modified to include (depending on tolerability, resistance and prior antiretroviral history) one or more agents that cross the
placenta. A woman conceiving on dolutegravir should see her physician as soon as possible to discuss current evidence on neural tube defects.

Q

When to start ART?

What factors effect when it is started?

A

All women not on cART should commence cART:
• As soon as they are able to do so in the second trimester where the baseline viral load
≤30,000 HIV RNA copies/mL;
• At the start of the second trimester, or as soon as possible thereafter, in women with a
baseline viral load of 30,000–100,000 HIV RNA copies/mL;
• Within the first trimester if viral load >100,000 HIV RNA copies/mL and/or CD4 cell count is less than 200 cells/mm3
.
All women should have commenced cART by week 24 of pregnancy.

Q

What cART to start

A

Women are recommended to start tenofovir DF or abacavir with emtricitabine or lamivudine as
a nucleoside backbone.

It is recommended that the third agent in cART should be efavirenz or atazanavir/r, as these are
agents with the most safety data in pregnancy.

Q

Is zidovudine monotherapy ever indicated?

A

Zidovudine monotherapy is not recommended and should only be used in women declining
cART with a viral load of <10,000 HIV RNA copies/mL and willing to have a caesarean section (CS).

PI monotherapy, tenofovir alafenamide, darunavir/cobicistat and elvitegravir/cobicistat are not
recommended in pregnancy.

Q

When to start ART

A

A woman who presents after 28 weeks should commence cART without delay.

If the viral load is unknown or >100,000 HIV RNA copies/mL, a three- or four-drug regimen that
includes raltegravir 400 mg bd or dolutegravir 50 mg od is suggested.

Management of an untreated woman presenting in labour at term.
• All women should be given a stat dose of nevirapine 200 mg; and commence oral zidovudine 300 mg and lamivudine 150 mg bd; and raltegravir 400 mg bd;and receive intravenous zidovudine for the duration of labour.

Q

Why do we want repeated LFTs?

A

LFTs should be repeated at 2 and 4 weeks after commencing ART to detect evidence of
hepatotoxicity or immune reconstitution inflammatory syndrome (IRIS) and then monitored
regularly throughout pregnancy and postpartum.

Q

What anomaly screening test should be offered for HIV + woman

A

The combined screening test for fetal aneuploidies and non-invasive prenatal testing (NIPT) for
those who screen as high risk is recommended as this has the best sensitivity and specificity and
will minimise the number of women who may need invasive testing.

21
Q

When is prenatal diagnostic testing considered safe?

A

Invasive prenatal diagnostic testing should not be performed until after the HIV status of the
woman is known, and should ideally be deferred until HIV viral load has been adequately
suppressed to <50 HIV RNA copies/mL

If not on cART and the invasive diagnostic test procedure cannot be delayed until viral
suppression is achieved, it is recommended that women should commence cART to include
raltegravir and be given a single dose of nevirapine 2–4 hours prior to the procedure..

22
Q

When is ECV safe ?

A

External cephalic version (ECV) can be offered to women with plasma viral load <50 HIV RNA
copies/mL.

23
Q

When to decide re MOD?

A

For women taking cART, a decision regarding recommended mode of delivery should be made after review of
plasma HIV viral load results at 36 weeks.

24
Q

When is a NVD safe?

A

For women with a plasma viral load of <50 HIV RNA copies/mL at 36 weeks, and in the absence of obstetric contraindications, planned vaginal delivery should be supported.
If levels <50 then VBAC safe

25
Q

What about borderline viral loads? what is the recommendation re MOD?

A

For women with a plasma viral load of 50–399 HIV RNA copies/mL at 36 weeks, pre-labour CS
(PLCS) should be considered, taking into account the actual viral load, the trajectory of the viral
load, length of time on treatment, adherence issues, obstetric factors and the woman’s views.

For women with SROM and a last measured plasma viral load of 50–399 HIV RNA copies/mL,
immediate CS is recommended, but should take into account the actual viral load, the trajectory of the viral load, length of time on treatment, adherence issues, obstetric factors and the woman’s views.

26
Q

When is a ELSCS recommended?

A

Where the viral load is ≥400 HIV RNA copies/mL at 36 weeks, PLCS is recommended.

Where the indication for CS is the prevention of vertical transmission, CS should be undertaken
at between 38 and 39 weeks’ gestation.

Where PLCS is undertaken only for obstetric indications and plasma viral load is <50 HIV RNA
copies/mL, the usual obstetric considerations apply and the CS will usually be performed after
39 weeks’ gestation.

27
Q

HIV + PROM

A

In all cases of term pre-labour SROM, delivery within 24 hours should be the aim.
If maternal HIV viral load is <50 HIV RNA copies/mL, immediate induction or augmentation of
labour is recommended in women who have pre-labour SROM, with a low threshold for
treatment of intrapartum pyrexia.

28
Q

PROM + high viral load?

A

For women with SROM and maternal HIV viral load ≥400 HIV RNA copies/mL, immediate CS is
recommended

29
Q

How to manage PPROM over 34 weeks?

A

The management of preterm SROM at ≥34 weeks is the same as that of term SROM, except that
women at 34–37 weeks’ gestation will require group B streptococcus prophylaxis in line with
national guidelines.

30
Q

How to manage PPROM

A

When premature SROM occurs at <34 weeks:
• Intramuscular steroids should be administered in accordance with national guidelines;
• Where HIV viral load is not controlled, this should be optimised;
• There should be multidisciplinary discussion about the timing and mode of delivery

31
Q

When is Intrapartum intravenous zidovudine infusion is recommended in the following circumstances:

A

For women with a viral load >1000 HIV RNA copies/mL plasma who present in labour or with
SROM or who are admitted for PLCS.
For untreated women presenting in labour or with SROM in whom the current viral load is not
known;
The use of intrapartum intravenous zidovudine infusion can be considered in women on cART with a plasma HIV viral load between 50 and 1000 HIV RNA copies/mL.

32
Q

Where to deliver?

A

All women living with HIV are recommended to give birth in a facility that has direct access to paediatric care (i.e. a co-located birth centre or obstetric unit).

33
Q

Can HIV + Woman have a waterbirth?

A

There is scant safety evidence to support water births in women living with HIV; however,
women who choose a water birth should be supported to achieve this where the viral load is <50 HIV RNA copies/mL.

34
Q

Does does very low risk to neonates mean?

What is the treatment?

A

Two weeks of zidovudine monotherapy is recommended if all the following criteria are met:
• The woman has been on cART for longer than 10 weeks;
AND
• Two documented maternal HIV viral loads <50 HIV RNA copies/mL during pregnancy at
least 4 weeks apart;
AND
• Maternal HIV viral load <50 HIV RNA copies/mL at or after 36 weeks.

35
Q

What is a low risk neonate? how to treat?

A

Extend to 4 weeks of zidovudine monotherapy:
• If the criteria in 9.1.1 are not all fulfilled but maternal HIV viral load is <50 HIV RNA
copies/mL at or after 36 weeks;
• If the infant is born prematurely (<34 weeks) but most recent maternal HIV viral load is <50 HIV RNA copies/mL.

36
Q

HIGH RISK neonates - how to treat

who to treat

A

Use combination PEP if maternal birth HIV viral load is known to be or likely to be >50 HIV RNA
copies/mL on day of birth, if uncertainty about recent maternal adherence or if viral load is not
known.

37
Q

When to start neonatal treatment

What is there is maternal resistance to Tx

A

Neonatal PEP should be commenced as soon as possible after birth, and at least within 4 hours.
In the context of known maternal resistance to zidovudine with VERY LOW or LOW RISK,
zidovudine monotherapy is still recommended for infant PEP.
If HIGH RISK (combination PEP indicated) and there is a history of documented maternal
zidovudine and/or nevirapine resistance, seek expert advice. If advice is not immediately
available, commence standard three-drug PEP (zidovudine, lamivudine and nevirapine) until
guidance is provided.

38
Q

Max length of time to give neonatal PEP

A

Infant PEP should not be given beyond 4 weeks

PEP should not be restarted unless significant subsequent exposure (e.g. maternal viral load
detectable during breastfeeding). Seek expert advice regarding need for PEP following breast
milk exposure during an episode of maternal viraemia.

39
Q

Do you give infants PCP

pneumocystis pneumonai prophylaxis

A

Co-trimoxazole prophylaxis is recommended from 1 month of age if HIV PCR screening is
positive at any stage or if the infant is confirmed to be diagnosed with HIV. This should only be
stopped if HIV infection is subsequently exclude

40
Q

Breastfeeding and HIV

A

In the UK and other high-income settings, the safest way to feed infants born to women with
HIV is with formula milk, as there is no on-going risk of HIV exposure after birth. We therefore
continue to recommend that women living with HIV feed their babies with formula milk.
Women advised not to breastfeed for their baby’s health should be provided with free formula feed to minimise vertical transmission of HIV.

Women not breastfeeding their infant by choice, or because of viral load >50 HIV RNA
copies/mL, should be offered cabergoline to suppress lactation.

41
Q

If a mum decides to breast feed

A

When a woman decides to breastfeed, she and her infant should be reviewed monthly in clinic
for HIV RNA viral load testing during and for 2 months after stopping breastfeeding

42
Q

How to test neonates

fir HIV status that are not breast fed?

A
  • During the first 48 hours and prior to hospital discharge;
  • If HIGH RISK, at 2 weeks of age;
  • At 6 weeks (or at least 2 weeks after cessation of infant prophylaxis*);
  • At 12 weeks (or at least 8 weeks after cessation of infant prophylaxis*);
  • On other occasions if additional risk;
  • HIV antibody testing for seroreversion should be checked at age 18–24 months
43
Q

How to test neonates

fir HIV status that are not breast fed?

A
  • During the first 48 hours and prior to hospital discharge;
  • At 2 weeks of age;
  • Monthly for the duration of breastfeeding;
  • At 4 and 8 weeks after cessation of breastfeeding;
  • HIV antibody testing for seroreversion should be checked at age 18–24 months.
44
Q

How to manage HIV exposed children (not affected)

A

In light of evidence for possible increased infectious morbidity in HIV exposed but uninfected
(HEU) children, timely routine vaccination should be ensured and general practitioners (GPs),
health visitors and secondary care physicians should be made aware of possible increased risk in
order to inform decisions when assessing risk in primary care.

45
Q

Postpartum what do to with their tx + other management steps

A

Continue it
Women should have their support needs assessed postpartum and be referred to appropriate
services in the Trust, community and/or voluntary groups without delay.
All women should be reviewed in the postnatal period by a named member of the MDT within 4–6 weeks.
Women should have their mental health needs assessed postpartum and those assessed as
having mental health issues should be referred to appropriate services in the Trust, community
and/or voluntary
groups without delay.

46
Q

Who else should be testing if a woman is HIV +

A

For the woman newly diagnosed with HIV in pregnancy, testing of her partner and/or other
children should be completed

47
Q

Who gets PCP prophylaxis

A

Indication CD4 count under 200

Co trimoxazole is the agent recommended in pregnancy for PCP prophylaxis
