INTRODUCTION

• HIV the aetiological agents of AIDS have been identified as HIV-1 and HIV-2. These viruses belong to the Lentivirus group of Retroviridae family.

• HIV continues to be a major global public health issue, having claimed more than 36 million lives so far.

• The Human Immunodeficiency Virus (HIV) targets the immune system and weakens people's surveillance and defense systems against infections and some types of cancer.

Page 8: PRE-TEST 1.Regargind latest guideline on initiation of ARV start at CD4 of A. 200cc/ml C..                                 Publish Valentine Page,  Modified 4 months ago

• As the virus destroys and impairs the function of immune cells, infected individuals gradually become immunodeficient

• Immunodeficiency results in increased susceptibility to a wide range of infections and diseases that people with healthy immune systems can fight off

• . The most advanced stage of HIV infection is Acquired Immunodeficiency Syndrome (AIDS), which can take from 2 to 15 years to develop depending on the individual

• . AIDS is defined by the development of certain cancers, infections, or other severe clinical manifestations

Page 9: PRE-TEST 1.Regargind latest guideline on initiation of ARV start at CD4 of A. 200cc/ml C..                                 Publish Valentine Page,  Modified 4 months ago

• The transmission of HIV from an HIV-positive mother to her child during pregnancy, labour, delivery or breastfeeding is called mother-to-child transmission.

• In the absence of any interventions transmission rates range from 15-45%.

• This rate can be reduced to levels below 5% with effective interventions.

• These can be achieved by setting global norms and standards for HIV prevention, care and treatment of pregnant women, mothers and their children,

SCOPE OF HIV/AIDS IN WOMEN

HIV spreads rapidly, particularly among young women.

These women are in their most productive and reproductive years.

There are various factors that make women vulnerable to HIV infection, These factors include: Biological factors Socio-cultural factors

Page 21: PRE-TEST 1.Regargind latest guideline on initiation of ARV start at CD4 of A. 200cc/ml C..                                 Publish Valentine Page,  Modified 4 months ago

BIOLOGICAL FACTORS

• Women have larger surface area of the genital mucosa

• Semen infected with HIV contains higher concentrations of virus than vaginal fluid.

• Young women have immature cervix and scanty vaginal secretion hence barrier to infection is reduced

• Women become more vulnerable again after menopause

• Tearing and bleeding during intercourse further increased predisposition to infection. This can occur during rough vagina sex, anal sex, dry sex or rape

• Untreated STIs multiplies the risk of HIV infection by 300-400%.

Page 22: PRE-TEST 1.Regargind latest guideline on initiation of ARV start at CD4 of A. 200cc/ml C..                                 Publish Valentine Page,  Modified 4 months ago

SOCIO-CULTURAL FACTORS

• Economic and societal approved dependency on men

• Rights of women are abused and often violated.

• Condom use by stable partners is often frowned at.

• Cultural practices often expose women to multiple partners e.g polygamy, widow inheritance, wife hospitality

• Gender inequalities which negatively impacts on and their effect on seeking care and prevention efforts

• Burden of being the care provider in the home may supercede the need to care for herself

Principles of ARV useStrict adherence critical but a challenge in pregnancyARVs have side effects that need clinical and lab

monitoringBeware of drug interactionsResistance may develop if adherence is not excellent or

if drug interactions affect drug levels, resistance may occurResistance may be spread to baby and to partner

With excellent adherence and monitoring, risks of ARV are minimised and benefits are maximised

HIV IN PREGNANCY: DRUG TREATMENT

• The goal in pregnancy is to reduce viral load to undetectable to minimize perinatal transmission.

• However, the woman should be counselled and willing to adhere to the regimen

• She should be counselled on the risks and benefits of the ARVs

• A first-line regimen is a combination of drugs that will be used in a patient who has no prior ART experience. This means that the patient has never taken ARV drugs before.

• Most commonly, a first-line regimen will consist of two NsRTI's and one NNRTI.

• Many patients will eventually develop failure of therapy: the first-line therapy will not be effective anymore (often because the drugs were not taken correctly). In that case, the doctor may decide to switch to a second-line regimen.

• Usually, the second-line regimen will consist of 2 NRTI + 1 PI.

ART should be initiated in all pregnant women based on the following criteria.

• CD4 count of less than or equal to 350 irrespective of WHO clinical staging.

• WHO stages III and IV irrespective of CD4 cell count.• Nigerian guideline Recognizes pregnancy as an indication for

prophylactic ART irrespective of CD4 count, viral loads or clinical staging

Women With CD4 Count above 350 Cells/mm3

Women With CD4 Count beloW 350 Cells/mm3

ChilD receives

option a During pregnancy: AZT starting as early as 14 weeks of pregnancy At delivery: single-dose NVP and first dose of AZT/3TC After delivery: daily AZT/3TC through 7 days postpartum

Triple ARVs started as soon as diagnosed and continued for life

Daily prophylaxis (NVP) from birth until 1 week after all breastfeeding has finished; or, if not breastfeeding or if mother is on treatment, through age 4–6 week

Option b Triple ARVs starting as early as 14 weeks of pregnancy continued through childbirth (if not breastfeeding) or until 1 week after all breastfeeding has finished

Daily prophylaxis (NVP or AZT) from birth through age 4–6 weeks regardless of infant feeding method

Option b+ Triple ARVs started as soon as diagnosed and continued for life

CHOICE OF ARV”S IN PREGNANCY

Combination regimens, usually including 2 NRTIs with either a NNRTI or 1 or more protease inhibitors (PIs) are recommended

AZT + 3TC + EFV/NVPAZT + 3TC (or FTC) + EFV/NVP

AZT + 3TC + LPV/rAZT + 3TC + ABCTDF + 3TC (or FTC) + EFV/NVP

NOTE

Nevirapine is avoided in women with CD4 count >250. EFV is avoided in the first trimester

• Any pregnancy regimen should include ZDT unless contraindicated

• Combination HAART (3 drugs) is associated with vertical transmission rates of <2% and is considered standard of care (regardless of VL or CD4+)

• Safety of HAART in pregnancy is reassuring

• Continue drugs during labor

NEW RECOMMENDATIONS IN WHO ART GUIDELINES (2013)

• • Earlier initiation of ART (CD4 ≤ 500)

• • 1) Immediate ART for children below 5 years

• • 2) Harmonization of ART across populations (e.g., adults and pregnant women, B/B+) and age groups

• • 3) Simplified, fewer, and less toxic 1st line regimens (TDF/3TC/EFV)

• • 4) Improved patient monitoring to support adherence and detect failure (increased use of VL)

• • 5) Recommend task shifting, decentralization, and integration

NATIONAL RECOMMENDATIONS 2010INFANTS

• HIV+ Mothers ( whose infants are HIV uninfected or of unknown HIV status) should exclusively breastfeed their infants for the first 6 months of life, introducing appropriate complementary foods thereafter, and continue breastfeeding for the first 12 months of life.

Breastfeeding should then only stop once a nutritionally adequate and safe diet without breast milk can be provided.

When HIV-infected mothers decide to stop breastfeeding (at any time) they should do so gradually within one month

Page 68: PRE-TEST 1.Regargind latest guideline on initiation of ARV start at CD4 of A. 200cc/ml C..                                 Publish Valentine Page,  Modified 4 months ago

: MONITORING OF THERAPY • Check viral load, CD4+, LFTs, FBC every trimester• Consider change of therapy if viral load still detectable in 3-6

months• Exclude adherence problems

• Is she taking her meds??

• Baseline ARV resistance testing • HAART naïve (new) cases• HAART re-starts• if suboptimal viral suppression

• Following delivery, avoid milking the cord. • The baby should be thoroughly dried, and any remaining maternal

blood and amniotic fluid should be removed.• Vigorous suctioning of the infant’s mouth and pharynx should be

avoided• Vaginal cleansing using disinfectants such as chlorhexidine where

SVD is anticipated.• Use partogram to monitor labour progress.• Determine mother’s feeding choice

CONCLUSION

PMTCT is a success story in HIV prevention.A proper understanding of the basic principles of HIV

and ARV use is all that is necessary to achieve this success.

The implementation of the core PMTCT interventions based on these principles will reduce MTCT from 40% to about 2%.
