Presentation Outline Backgrounds, objectives, and methodology LTBI Survey Results: I. Low-Incidence Countries II. (Estimated TB incidence<100/100,000 and upper/upper-middle income) High-incidence countries (Estimated TB incidence >=100 or lower/lower-middle income) III. National policy on preventive therapy for contacts of MDR-TB IV. Systematic screening for LTBI and ACF
WHO LTBI Guidelines Guidelines on the management of latent tuberculosis infection (high and upper middle-income countries with TB incidence <100/100, 000) WHO guidelines 2014 http://apps.who.int/iris/bitstream/10665/136471/1/9789241548908_eng.pdf Recommendations for investigating contacts of persons with infectious tuberculosis in low- and middle-income countries WHO guidelines 2012 http://apps.who.int/iris/bitstream/10665/77741/1/9789241504492_eng.pdf 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) http://whqlibdoc.who.int/publications/2011/9789241500708_eng.pdf
LTBI Survey Objectives 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
LTBI Survey Methodology Countries in WHO European regions N=55 TB incidence<100/100,000 and upper/upper-middle income N=45 TB incidence>=100/100,000 or lower/lower-middle income N=10 Participated in the survey N=36 (80%) Participated in the survey N=8 (80%)
Target countries for LTBI TB >=100 or lower/lower-middle income TB Incidence>=100 or lower/lower-middle income TB <100 and upper/upper-middle income TB incidence<100 and upper/upper-middle income
I. LTBI Survey Results for Low- Incidence Countries (Estimated incidence<100/100,000 and upper/upper-middle income)
National policy on systematic screening for LTBI 83% of countries have a national policy for LTBI screening (30/36) N=36 % of countries targeting risk groups strongly recommended N=36 % of countries targeting risk groups conditionally recommended Denominator: All countries which responded to the survey including those without a national policy
National policy on systematic screening for LTBI N=36 % of countries targeting risk groups not recommended
Screening Frequency for LTBI N=15 HIV 3 3 4 4 1 Household or close contacts, Children< 5years N=24 8 2 1 13 Ad hoc research Periodically < 1year Annually Periodically > 1 year Unknown N=22 Household or close contacts, aged>=5years 8 1 1 12 Compromised immune status N=12 2 6 4
Initial Screening methods for LTBI HIV N=15 1 1 6 4 1 2 Household or close contacts, children<5years N=26 2 2 5 1 16 TST IGRA Parallel testing with TST and IGRA TST followed by IGRA for confirmation Other More than one option Unknown N=22 Household or close contacts, aged>=5years 5 1 2 4 3 7 Compromised immune system N=12 2 1 2 2 2 3
Tools used to exclude active TB N=30 What does other include? What does combination of the above include, Symptom + Chest X-ray?
Preventive treatment regimens N=30 Recommended preventive treatment regimens (multiple answers) Single regimen Multiple regimen
Monitoring and Evaluation for LTBI 39% of countries are monitoring and evaluating LTBI activities (14/36) N=14 Monitoring and Evaluation Indicators
II. LTBI Survey Results for High- Incidence Countries (TB >=100 or lower/lower-middle income)
National policy on systematic screening for LTBI 62% of countries have a national policy for LTBI screening (5/8) N=8 % of countries targeting risk groups strongly recommended % of countries targeting risk groups not recommended
Screening frequency and methods and for LTBI Household or close contact, aged>=5 years Household or close contact, children<5 years Screening Frequency Household or close contact, aged>=5 years Household or close contact, children<5 years Data for HIV not shown as only 1 country targeting this risk group Screening Method
Preventive treatment regimens N=5 Recommended preventive treatment regimens
Monitoring and Evaluation for LTBI 62% of countries are monitoring and evaluating LTBI activities (5/8) N=5 Monitoring and Evaluation Indicators
III. Survey Results: National policy on preventive therapy for contacts of MDR-TB
Monitoring and Evaluation for LTBI Among low incidence countries, 36% have a national policy on preventive therapy for contacts of MDR-TB (13/36) Is preventive treatment recommended? Unanswered 8% N=13 N=13 Yes 23% Is clinical follow-up recommended? No 8% No 69% Yes 92% Among high incidence countries, only one indicated to have the policy. Clinical follow-up, but not preventive treatment, was recommended (1/8).
IV. Survey Results: systematic screening for LTBI and ACF
Risk Groups targeted for LTBI and ACF (Low vs. High incidence) Incidence<100 and upper/upper middle countries HIV Household or close contacts, children<5years Immigrants from high TB burden countries 39% 11% 17% 33% 72% 11% 11% 6% 22% 47% 31% TB Incidence>=100 or lower income HIV Household or close contacts, children<5years Immigrants from high TB burden countries 13% 87% 38% 12% 50% 50% 50%
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.
