Tuberculosis in Indonesia: Tipping the balance towards better control Bachti Alisjahbana Medical Faculty, Padjadjaran University, TB Operational Research Group, National TB Program, Indonesia
Overview TB Situation Program challenges Operational research Biomedical research Conclusion
Indonesia Pop = 247 million
22 High Burden Countries, 2012 China 14.3% Indonesia 5.8% South Africa 4.9% India 21.1% Nigeria 4.9% Bangladesh 3.8% Ethiopia 3.3% Pakistan 3.2% Other 15.9% Philippines 2.7% • In Indonesia : • Prevalence: 730.000 (297/100 thousand) • Incidence: 460.000 (185/100 thousand) • Mortality: 67.000 • HIV in TB = ~3% WHO report 2013
Target CDRI ndo 75%, Global 70% Target SR Indo 86%, Global ≥ 85% s/d 3rd Quarter (data gathered by 10 Jan 2012)
Number of TB cases in Bandung municipalyear 2012 (population of ~ 2,4 million) PHC: Public Health Center; P:pulmonary; EP:Extra pulmonary; AFB: Acid Fast Bacilli
Overview TB situation Program challenges Operational research Biomedical research Conclusion
TB Laboratories 3 national Surabaya Bandung Univ Indo, Jakarta 2 referral lab. just passed QA. 5.566 TB lab. 59% (3.284) EQAS, 75% good result
TB-MDR Among new patients, resistance to any drug 17.1% MDR-TB 1.8%. Retreatment cases, Resistance 34.3% and MDT 17.1%. WHO estimated 6900 cases are MDR TB (annual incidence). Total notification MDR-TB was 428, (0.12% coverage).
TB-HIV HIV prevalence in new TB is 3.3%. ~ 1% TB patients know their HIV status. Among HIV positive, only 29% enrolled on ART.
National Strategy 2016Toward a free-TB, healthy, just and self- reliant society Technical Strategies Scaling-up and improve quality DOTS Addressing TB/HIV, MDR-TB, & the needs of poor and vulnerable Engaging all public and private providers in implementation of ISTC. Empowering TB patients & communities
National Strategy 2010-2016 Functional Strategies Strengthening health system, HRD and TB control program management Increasing commitment of central and local government Enhancing research, development and utilization of strategic information
Overview TB Situation Program challenges Operational research Biomedical research Conclusion
TB Operational Research Group (TORG) Under the NTP Facilitate operational research (OR) Increase capacity to conduct OR through intensive courses Review TB research proposals submitted to NTP Provide technical assistance in OR at National level. Facilitate implementation of OR results in program
Evaluation of implementation of Xpert-Mtb-Rif National level OR 5 Xpert deployed in 2012, 10 more in 2013 Aiming for HIV and MDR-TB Increase D/ yield, faster detection MDR TB Hesitation rely only xpert Culture still needed
TB prevalence surveyPreliminary findings Smear-positive TB prevalence higher than previously estimated* Probably more sensitive screening, & diagnosis Prevalence in rural > urban Prevalence peaked in 25-34 age. Ongoing significant transmission? Gaps between prevalence and notifications are greater in men and oldest age
Overview TB Situation Program challenges Operational research Biomedical research Conclusion
Biomedical research • New findings • → new challenges
First project (2000-2005) • Immunogenetic basis of susceptibility to and disease manifestations from tuberculosis • Why patient gets TB • What immunogenetic pattern? • Others condition? • 900 Cases, 1000 Control • Funded by KNAW

EC, Fp7 To determine prevalence of DM among TB patients & vice versa feasible, accurate and cost-effective ways of screening. DM management level required with TB treatment glucose control effect on TB treatment outcome Pathopysiological studies
Pharmacokinetic studies Rifampicin plasma concentration is significanty reduced in TB-DM patient Nijland et al, 2006, CID
TB Diagnostic (Lidya Chaidir et al, 2013)
Bacterological studiesDrug Sensitivity Testing? Figure 3. AMK = Amikacin, INH = Isoniazid, RIF=Rifampicin, PAS=Para aminosalisilic acid, ETB=Ethambutol, STR=Streptomicin. Numbers shows antibiotic concentration in medium (mg/l). Multiwell method The proportional method
TB Beijing genotype • Related with higher disease severity? • Our studies • More severe • More treatment failure R. Van Crevel, EID, 880 Vol. 7, No. 5, September-October 2001
Population Structure of M. tuberculosis in Papua vs Java Mtb Finger Printing, show huge variability across Indonesian Islands MIRU-VNTR and MLPA later shows more distinctive power (Lidya Chaidir et al, 2013)
Latent TB Treatment • Multicenter clinical trial (2012-now) • latent TB (TST +) • 800 adult, 300 child • 4Rif vs 9INH • safety & efficacy • immunological pattern
