TB, HIV and Drug UseThe overview

• TB is caused by infection with a bacteria – Mycobacterium tuberculosis

• It is spread like the common cold through respiratory droplets in the air– Coughing, sneezing, talking, singing…

• 1/3 of the world’s population are infected with TB (not active disease)

• Bacteria lives dormant in the lung – latent TB infection

• Only 5-10% actually develop TB disease during their lifetime (if HIV negative)

• If HIV positive this increases to 10% every year

What is Tuberculosis (TB)?What is Tuberculosis (TB)?

What is HIV/TB?What is HIV/TB?

• One third of the 33 million people living with HIV is co-infected with TB

• TB is a leading cause of death among people living with HIV

• The majority of cases of tuberculosis in people living with HIV, occur in sub-Saharan Africa, where up to 80% of TB patients may be co-infected with HIV

• Also very high levels of co-infection in certain high risk groups

Global response in 2008Global response in 2008

• 1.4 million HIV positive TB cases– 500,000 people died of HIV associated TB

• Only 1.4 million TB patients (out of 9m) tested for HIV– Of those HIV positive; 200,000 given CPT and

100,000 ART

• Only 1.4 million PLHIV (out of 33.3m) screened for TB– Only 48,000 given IPT

• 8 out of every 100 IDUs received OST

HIVHIV• HIV epidemic began 25 years

ago

• History of strong political advocacy/activism

• Strong global awareness

• Rapid test on finger prick or saliva in minutes, simple and accurate

• Dozens of new drugs to treat HIV

TBTB• TB thousands of years old

• Recent adoption of advocacy/activism

• TB a forgotten disease

• Diagnostic test more than 120 years old, tedious & inaccurate

• No new TB drugs for >40 years

Power of advocacyPower of advocacy

No more people living with HIV, dying of TB!No more people living with HIV, dying of TB!

BarriersBarriers• Advocacy/activism• Inadequate tools/lack of

research• Weak health systems –

human resources • Lack of collaboration and poor

integration at patient level• No integration with harm

reduction programs– No provision OST

• Poor implementation of the Three I’s

• Lack of social mobilization• HIV continues to spread

SummarySummary• TB, HIV and drug use closely linked

• TB is preventable & curable in people living with HIV & drug users

• Universal access means access to comprehensive TB and HIV prevention, care and treatment linked to services for people who use drugs

• All stakeholders in TB, HIV and drug use need to work closely together to reduce the interrelated impact
