  6. Current Global Status • 8.8 million new cases of TB in 2003 • 7.6% of total cases HIV+ (674 000) = 12% of adult cases • TB notifications and estimated incidence stable or decreasing in 5 WHO regions, increasing in Africa, due to HIV • Global estimated incidence grew 1% • Global prevalence and mortality rates falling

  10. TB/HIV in Africa – 2003 • Total cases annually in SSA 2.35m • Estimated number (%) HIV + 596k (25%) • Cases notified annually in SSA 996k • Estimated no. of notified HIV+ 243k • % Adult TB patients HIV+ 37% • Deaths from TB due to HIV 207k • % of HIV deaths due to TB 15% • Treatment success 73% (average 82%)

  11. Countries ranked by a) Number: the number of TB cases attributable to HIV (thousands) and b) Rate: the number of TB cases attributable to HIV per 100,000 population. Above red line: 80% of total number; above blue line: 90% of total number Rank Country Number Country Rate Rank Country Number Country Rate 1 S.

  12. Epidemiological summary • TB coming under control everywhere except Africa (and Eastern Europe) • HIV is the proximal cause in Africa • East and Southern Africa worst hit • Women more affected than men by TB/HIV • Mortality from TB rising with HIV • Most TB in Africa in HIV uninfected • Notwithstanding, TB control nearing 2005 targets • MDGs likely to be met, except in Africa and Eastern Europe • Battleground for TB MDGs shifts towards Africa

  13. The policy response

  14. WHO-recommended Stop TB Strategy to Reach the 2015 MDGs • Pursuing quality DOTS expansion and enhancement • Political commitment • Case detection through bacteriology • Standardised treatment, with supervision and patient support • Effective drug supply system • Monitoring system and impact evaluation Additional components from October 2005 2 Addressing TB/HIV and MDR-TB 3. Contributing to health system strengthening 4. Engaging all care providers 5. Empowering patients and communities 6. Enabling and promoting research

  15. Therefore DOTS alone is insufficient to control TB where HIV is high and rising

  16. Additional options:TB/HIV Collaborative Activities Decrease the burden of tuberculosis in people living with HIV/AIDS • Establish intensified tuberculosis case-finding • Introduce isoniazid preventive therapy • Ensure tuberculosis infection control in health care and congregate settings Decrease the burden of HIV in tuberculosis patients • Provide HIV testing and counselling • Introduce HIV prevention methods • Introduce co-trimoxazole preventive therapy • Ensure HIV/AIDS care and support • Introduce antiretroviral therapy Establish mechanisms for collaboration • Set up a coordinating body for TB/HIV activities • Conduct surveillance of HIV prevalence among tuberculosis patients • Carry out joint TB/HIV planning • Conduct monitoring and evaluation

  17. TB/HIV policy guidance - 2004 Interim policy M&E Surveillance ART ProTEST lessons TBHIV Clinical HIV testing policy

  18. Experience from ProTEST, Malawi, South Africa, Zambia etc • TB/HIV collaboration possible and useful • Responds to huge unmet need • Filled a large policy void • Policy makers and managers convinced -> expansion • Involvement of all stakeholders critical • Additional staff essential • Technical support essential • More operational research/cultural understanding required to increase adherence to preventive treatments • Standard monitoring and evaluation tools needed • Joint TB/HIV work sets stage for ARVs

  19. Progress and operational issues

  20. Global Plan to Stop TB II, 2006-2015 Cost by type of investment 5.5 bn

  21. Countries involved • Making progress - Africa: • Botswana, Cote d'Ivoire, DRC, Ethiopia, Kenya, Malawi, Rwanda, South Africa, Tanzania, Zambia • Making progress elsewhere: • Brazil, Cambodia, Haiti, India, Thailand, Central America • Starting: • China, Indonesia, Mozambique, Namibia, Nigeria, Uganda, Vietnam

  22. Malawi • In year to July 2004, 27% TB patients received HIV test – 67% HIV +ve • Of those positive, 90+% received CPT • Of 22973 patients ever started on ART up to July 2005, 3081 (13%) due to TB • Of 5696 patients on ART in Q2 2005, 908 (16%) due to TB – 13% of all TB patients registered in Q2

  23. Comprehensive HIV treatment including DOT- TB/ART is feasible even in the poorest of settings (PIH Haiti)

  24. TB/HIV Expansion progress – Sept 2004 • Funding commitment is no longer the bottleneck • PEPFAR increasing TB/HIV element in 2006 country operational plans – ART targets cannot be met without involving TB programmes • TB/HIV emphasised in GFATM R5 – TB/HIV in: • 17/22 approved TB proposals • 6/25 approved HIV proposals • TB/HIV activities in most regions • 13/33 countries surveyed have coordination mechanism, 50% doing joint planning • Large human resource gap • Recording and reporting gap at peripheral level

  25. TB/HIV Diagnosis and Referral TB Control Program HIV Control Program HIV Suspect TB Suspect HIV testing centre TB Unit Active TB HIV Positive No TB HIV negative HIV Prevention HIV/AIDS Care TB Health Education DOTS

  26. Which model of integration ? HIV/AIDS TB ARV follow-up One stop service for TB-HIV co-infected HIV/AIDS TB + ARV TB/HIV TB TB patients Infectious disease chronic care unit

  27. Political and partnership commitments • Commission for Africa, G8, UN World Summit, African Union • Maputo declaration of TB: an emergency in Africa • Stop TB Partnership "blueprint" for action in Africa and WHO/AFRO lead in planning • TB/HIV Working Group • PEPFAR, GFATM and role for increasing WB MAP collaboration

  28. Political and partnership issues • TB is perceived as "just another HIV issue" • TB:HIV cultural differences • Treatment vs prevention • Impact of emphasis on HIV/AIDS treatment • Institutional divides • National TB Programmes, National AIDS Control Programmes, and National AIDS Commissions, CCMs

  29. Conclusions • WHO TB/HIV collaborative activity policy being implemented • Fast multiplication of activities but demand outstripping supply • Urgent need for monitoring and impact evaluation • Funds OK for now - human resources insufficient • Debate on operational issues and country by country resolution of constraints needed • Advocacy, political support, country assistance and close collaboration needed

  30. Mandela urges action to fight TBBy Chris Hogg BBC Bangkok BANGKOK: by Lawrence K. Altman – Nelson Mandela came to the 15th International AIDS Conference here Thursday to lend his prestige to the battles against tuberculosis and AIDS, two deadly diseases that are intricately linked. BANGKOK (Reuters) – The global war on AIDS could be lost if the world ignores tuberculosis, often a "death sentence" for people infected with HIV, former South African president Nelson Mandela said on Thursday.
