20 Introduction: PPTCT - MDR

21 Introduction Transmission from HIV infected mother to baby is the key mode of HIV transmission in children Annually about 14,000 New HIV Infections occur among children in India HIV infection causes about 10,000 deaths annually among children in India But It is possible to prevent HIV infection among children It is also possible to Minimize Mortality if children are infected Early detection and prompt treatment Paediatric HIV is thus amenable to prevention as well as effective management 21

22 Introduction (2) Currently available Anti-Retroviral drug regimen if given to HIV infected pregnant women can potentially Eliminate Risk of HIV transmission United Nations General Assembly adopted a resolution to work towards elimination of paediatric HIV by 2015 Government of India is committed to this goal 22

23 PPTCT Services: Evolution in India : Feasibility study in 11 COEs, launch of VCT services for pregnant women & SD Nevirapine to infected mother and exposed baby : Major expansion of these services in 6 high prevalence states with support from Global Fund (Round-2), and gradually across the country : VCT and PPTCT services merged in Integrated Counselling and testing Centre : Provider Initiated Testing and Counselling (PITC) strategy adopted for testing of Ante-Natal Cases (ANC) : Pilot of Sub-Centre level HIV screening strategy through frontline health workers. Launch of Early Infant Diagnosis services through ICTCs : WHO PMTCT Option- B adopted by Department Of AIDS Control and implemented in three high HIV prevalence states May/June 2013: National Strategic Plan for Scale-up of PPTCT services using Multi- Drug ARV regimen (Option-B), developed Jan 2014: ART for all HIV positive pregnant women irrespective of CD4 count / WHO clinical staging adopted by Department Of AIDS Control 23

24 National Strategic Plan: Vision, Goal and Objectives Vision: Women and children, alive and free from HIV Goal: To work towards elimination of paediatric HIV and improve maternal, newborn and child health and survival in the context of HIV infection Objectives: 1. To detect more than 80% HIV infected pregnant women in India 2. To provide access to comprehensive PPTCT services to more than 90% of the detected pregnant women 3. To provide access to early infant diagnosis to more than 90% HIV exposed infants 4. To ensure access to anti-retroviral drug (ARV) prophylaxis or Anti-Retroviral Therapy (ART) to 100% HIV exposed infants 5. To ensure more than 95% compliance with ARV /ART in HIV infected pregnant women and exposed children 24

33 Mother-to-child transmission Is the main cause of HIV infection in children It can occur during: Pregnancy Labour and delivery Breastfeeding 33

34 Factors that Increase Transmission of HIV to the child from the mother Maternal Factors during Pregnancy Maternal Factors during Delivery Factors while Breastfeeding

35 Factors that Increase Transmission of HIV to the child from the mother Maternal Factors during Pregnancy Maternal Factors during Delivery Factors while Breastfeeding High maternal viral load New HIV infection during pregnancy Advanced disease in the mother Viral, bacterial & parasitic placental infection Maternal malnutrition STI

36 actors that Increase Transmission of HIV to the child rom the mother Maternal Factors during Delivery Maternal Factors during Pregnancy Factors while Breastfeeding New HIV infection Advanced HIV disease/aids in mother High maternal viral load Prolonged labour and rupture of membranes Acute chorionamnionitis Invasive child birth procedures Premature birth of infant First infant in multiple birth

37 Factors that Increase Transmission of HIV to the child from the mother Maternal Factors during Delivery Maternal Factors during Pregnancy Factors while Breastfeeding New HIV infection during breastfeeding Advanced HIV disease/ AIDS in the mother High maternal viral load Duration of breastfeeding Mixed feeding Breast abscesses, nipple fissures, & mastitis Maternal malnutrition Oral disease in infant

38 THE Most Important Factor for Transmission of HIV is.. High Viral Load in Mother

39

40 India National Technical Resource Group (TRG) recommendation on PPTCT All positive pregnant women including those presenting in labour and breast feeding women with HIV should be initiated on a triple ART irrespective of CD4, for preventing Mother-to-Child Transmission risk and should continue life long ART. The duration of NVP to infant be minimum 6 weeks but more if ART to mother was started in late pregnancy, during or after delivery and has not been on adequate period of ART as to be effective to achieve optimal viral suppression (which is at least 24 weeks), then the infant NVP should be increased to 12 weeks. This recommendation on extended NVP duration applies to infants of breast feeding women only and not those on exclusive replacement feeding 40

41 Factors that decrease the risk of Mother-to-child transmission Highly efficacious PPTCT Regimen containing three ARVs have the potential to reduce the risk of mother to child transmission to less than 5% in breastfeeding populations and less than 2% in non-breast feeding populations. This is basic principle of new PPTCT guidelines 41

42 Life Long ART for all HIV Positive Pregnant women to prevent Mother to Child Transmission 42

43 How do ARV drugs work for PPTCT? Reduction of maternal viral load Loading fetus with ARVs that prevent transmitted virions from replicating 43

44 ART Eligibility Criteria for HIV positive Pregnant Women Clinical Staging Immune Status Irrespective of WHO Clinical Stage Irrespective of CD4 counts 44

45 Recommendations for HIV positive pregnant women Pregnant Women who are detected to be HIV infected during antenatal care should be initiated on ART (TDF+3TC+EFV) Tenofovir + Lamivudine + Efavirenz Regardless of clinical stage or CD4 count. But obtain sample for CD4 count before initiating or soon after initiating ART. The initiation of ART should not be delayed for want of CD4 test results.

46

47 Infants: ARV prophylaxis for infants born to women presenting in active labour All infants born to HIV positive pregnant women will receive Nevirapine syrup once daily for 6 weeks-irrespective of infant feeding option

48 Infants: ARV prophylaxis for infants born to women who did not receive any ART (Home Delivery) Infant should be stared on daily NVP prophylaxis at their first encounter with health services Daily infant NVP prophylaxis can be started even if more than 72 hours have passed since birth Daily infant NVP prophylaxis should continue for 6 weeks, by which time the mother should be linked to appropriate ART services The duration of daily infant NVP prophylaxis will depend on whether how long the mother is on lifelong ART

49 Dosage of NVP (10 mg of Nevirapine in 1ml suspension) Infants Birth Weight (gm) NVP daily dose (mg) NVP daily dose (ml) Duration Birth weight less than 2000 gm Birth weight between gm Birth weight more than 2500 gm 2 mg /kg. once daily.

56 Introduction HIV is a single-stranded RNA virus transmitted mostly through sexual contact, blood transfusion and contaminated hypodermic needles. HIV disease progresses very rapidly in young children, often leading to death. Asymptomatic children <18 months are often missed out on prevention, care, support and treatment. The new guidelines will attempt to ensure that HIV exposed and infected infants and children <18 months of age receive the required national essential package of care and support. The current test of choice in NACO s HIV care & treatment program is the HIV-1 DNA PCR test which detects HIV-1 proviral DNA integrated into the human genome.

57 Rapid HIV progression and higher risk of death in infected infants Without Anti Retroviral treatment: By age 1, one-third of all HIV-infected children will have died By age 2, half of all HIV-infected children will have died CD4 and viral load are poor predictors of disease progression in infants
