Presentation Outline
• Backgrounds, objectives, and methodology
• LTBI Survey Results:
(Estimated TB incidence<100/100,000 and upper/upper-middle income)
(Estimated TB incidence >=100 or lower/lower-middle income)
GLOBAL TB PROGRAMME
WHO LTBI Guidelines
Guidelines for intensified tuberculosis case-finding and isoniazid preventive therapy for people living with HIV in resource-constrained settings WHO guidelines 2011 (to be updated 2015)
Recommendations for investigating contacts of persons with infectious tuberculosis in low- and middle-income countries WHO guidelines 2012
Guidelines on the management of latent tuberculosis infection (high and upper middle-income countries with TB incidence <100/100, 000) WHO guidelines 2014

LTBI Survey Objectives
GLOBAL TB PROGRAMME
Conduct baseline assessment of LTBI policies and practices Will allow measurement of implementation
of LTBI guidelines Identify challenges and opportunities to
scale-up LTBI implementation Network and strengthen collaborative efforts
within EURO

Is preventive treatment recommended? Is clinical follow-up recommended?
Among high incidence countries, only one indicated to have the policy. Clinical follow-up, but not preventive treatment, was recommended (1/8).

Conclusions
Should additional risk groups be considered ? Should interventions be discouraged in other risk groups ? Should screening algorithms and frequency
be adapted to each risk group? Why is there a low level of implementation
of LTBI management in PLHIV.
