10 Epidemiology of HIV/AIDS

11 Global Scenario: Estimates PLHAs-33.4 Million (2008), 33.3 Million (2009)- 2/3 rd Cases in Sub-Saharan Africa, 1/10 th in SEA New Infections -2.7 Million (2008), 2.6 Million (2009) Deaths -2.0 Million (2008), 1.8 Million (2009) Infections /day (2008) Spread of Epidemic :- - High risk groups to General population From the Urban to Rural areas From High to Low Prevalence Areas Increasing Feminization (48%) Increased Sexual route spread in IDU High vulnerability of youth (15-24 Yrs)-40%

12 HIV Epidemic in India Country Profile: Low HIV prevalence (0.31%) Nearly 2.4 million people infected by HIV (7.2% of Global burden )- India carries the largest burden of HIV behind South Africa and Nigeria. HIV Transmission predominantly through heterosexual route (87%) Heterogeneous epidemic A wide variation in HIV prevalence between states, districts and intra districts even within the states Concentrated Epidemic focused in HRGs (FSWs, MSMs, IDUs) : High Risk Groups (2008 HSS)  Female Sex Workers (4.77%)  Men who have sex with men (6.9%)  Injecting Drug users (9.86%) Bridge Populations (2008 HSS) ▪ Migrants (2.3%) ▪ Truckers (1.48%)

22 Declining HIV Positivity rate in ICTC of Delhi

23 Goal: To halt and reverse the epidemic in India over the next five years Objectives: – Prevent new infections by saturating coverage of HRG through TI and scaled up interventions in the general population. – Provide greater care, support and treatment to larger numbers of PLHIV – Strengthen the infrastructure, systems and human resources in prevention, care, support and treatment programme at district, state and national levels – Strengthen the nationwide SIMS NACP-III ( ) : Goal & Objectives

24 Preventive Strategies 1.Prevention in High Risk Groups & Bridge Population- Targeted Intervention- Condom Promotion, BCC, STI management, ICTC referrals 2.Prevention in General Population-IEC, Blood Safety, STI prevention & treatment, PPTCT, ICTC, PEP

26 ICTC Programme

27 What is an ICTC ? Integrated Counseling & Testing Centre (ICTC) is a place where a person is counseled and tested for HIV on his own free will or as advised by a medical provider

28 Functions of an ICTC Early detection of HIV Provision of basic information on modes of transmission and prevention of HIV/AIDS so as to promote behavioral change and reduce vulnerability (both for HIV positive and negative) Link people with other HIV prevention, care and treatment services

29 Who needs to be counseled and tested in an ICTC ? It is not the mandate of ICTC to test everybody in the general population. – For e.g. Spouse of HIV-ve pregnant women are not to be tested without any valid indication Populations who are more vulnerable to HIV or practice high risk behavior are the target for counseling & testing at ICTCs. All clients with risky behaviour (FSWs, MSMs, IDUs, Bridge population), TB patients, patients with STIs,

30 Informed consent for HIV testing Pre-test counselling should include: —engagement and assessment —risk reduction and planning assistance —review and signing the consent form Post-test counselling should include: —presentation and encouragement —priorities and follow-up

31 What is confidentiality? Confidentiality arises when: There is a confidential relationship, the nature of which may be dependent on factors of trust, knowledge and skill Information which otherwise would not be divulged is exchanged For example, doctor–patient and counsellor– client relationship

32 Exceptions to confidentiality In the best interest of the patient (disclosure to medical team if necessary for the treatment of the patient) To protect another person (partner notification) Necessary in public interest

33 Confidentiality (contd) Mr X vs hospital Z (1998) 8SCC296 Supreme Court of India ruled that: Disclosure permissible to wife/prospective wife— her fundamental right to a healthy life outweighs the fundamental right of the PLHA to confidentiality.

35 CLIENTFLOWCLIENTFLOW

36 Aids to Communication in ICTC The IEC material which must be available in an ICTC are: TV and DVD player in a lockable stand for provision of information on HIV/AIDS to clients. Posters and Information Materials on the walls. Communication aids like flip charts. Condom demonstration models. Leaflets/pamphlets as take home material for clients.

37 HIV testing in an ICTC HIV Testing in an ICTC will be done only using rapid HIV diagnostic kits. The Laboratory Technician will ensure that results are delivered to the client the same day. All those who are detected HIV +ve are referred to the ART Centre All infants born to HIV +ve mothers will be tested for HIV using DNA PCR at minimum 6 weeks as per National guidelines.

38 Testing algorithm

39 Quality Assurance – Testing Internal – Lab Quality assessed through supervision – Standard Operating Procedures – Internal Control (+ve and –ve tested at regular intervals as per guidelines External – EQAS- Quarterly samples sent to 118 SRLs across the country – Every 6 months SRLs send coded samples to the ICTCs

40 PPTCT & EID Programme

41 Prevention of Parent to Child Transmission of HIV/AIDS (PPTCT)

42 Prevention of Parent to Child transmission (PPTCT) Programme – Mobilize pregnant women for PPTCT services and linkage of HIV +ve pregnant women for pre-ART registeration/ CD4 count test – Line listing of HIV +ve of pregnant mothers – Ensure institutional delivery and antiretroviral (ARV) prophylaxis – Nevirapine prophylaxis ( T. Nevirapine 200mg single dose for mother and for baby 2 mg/kg body wt.) – Follow up the mother–baby pair till 18 months. – Ensure that the HIV-positive mother and the baby are linked with the nearest ART centre. – Identify a family member whom the HIV-positive woman can confide in and who will be a source of support and strength for her.

43 Rationale For PPTCT Services in India Annual pregnancies-27 million HIV infected pregnancies-43,000 30% Transmission rate * Infected newborns-12,900 * Risk of transmission from HIV infected mother to child can be reduced by administration of life long triple ART/prophylactic Nevirapine tablet to the mother and baby

44 The PPTCT programme Pregnant woman come for ANC registration Pregnant woman coming for ANC are given pre- test counseling Pregnant woman is tested for HIV Pregnant woman undergoes post test counseling HIV positive pregnant woman Pregnant women coming directly for labour are given pre-test counseling Pregnant woman come directly to the Labour Room HIV negative pregnant woman 1.Referred to ART Centre for CD4 count & Pre ART Registration 2.Mother and Baby Given prophylactic Nevirapine 3.Babies born are tested at minimum 6 weeks using DNA PCR as per National Guidelines

45 Current PPTCT regimen in India Consists of a single dose of prophylactic Nevirapine (SD NVP) to the mother and the new born infant. SD NVP is effective, cheap, less toxic and programmatically easy to implement Currently ~ 70% of HIV +ve pregnant women and the infants born to them get prophylactic SD NVP at ICTC centres.

46 Infant Feeding Counseling for HIV+ve pregnant women The HIV +ve pregnant women will be given the option of replacement feeding or exclusive breast feeding for 6 months Guidelines give emphasis on exclusive breast feeding for 6 months through counseling.

66 Anti Retroviral Treatment

67 Goals of ART 1.Clinical goal To prolong life & improve quality of life 2.Virological goal Greatest possible reduction in viral load for as long as possible to halt disease progression and to prevent or delay resistance 3.Immunological goal Immune reconstitution - CD4 within normal range

68 Eradication of HIV? Not yet… And …. …in spite of plasma RNA below detection, there is evidence of genetic evolution in reservoirs.

69 WHEN TO START? - Initiation of ART in Adults and Adolescents National Guideline Revised National Guideline (April 2009) WHO Clinical Staging CD4 (cells/cu.mm) I and IITreat if CD4 Count < 350 III Treat irrespective of CD4 Count IV

70 National ART regimen First-line ART: First-line ART is the initial regimen prescribed for an ART naïve patient when the patient fulfils national clinical and laboratory criteria to start ART. (Current NACO treatment guidelines for first-line ART recommends two classes of drugs for initial treatment ie 2 NRTI + 1 NNRTI.) Zidovudine / Lamivudine / Nevirapine Or Stavudine / Lamivudine / Nevirapine ( Efavirenz in place of Nevarapine if coinfected with TB or side effects with NVP, Tenofovir for special situations only)

71 Initiating ART: Patient Education It is not curative, but prolongs life Treatment is lifelong, expensive High level of adherence is critical (>95%) Short and long term adverse events Drug interactions Safer sex still essential Do not share drugs with friends, family members Start ART when patient is ready
