ABSTRACTMIC testing forMycobacterium tuberculosisis now commercially available. Drug susceptibility testing by the MycoTB MIC plate has not been directly compared to that by the Bactec MGIT 960. We describe a case of extensively drug-resistant tuberculosis (XDR-TB) in Tanzania where initial MIC testing may have prevented acquired resistance. From testing on archived isolates, the accuracy with the MycoTB plate was >90% for important first- and second-line drugs compared to that with the MGIT 960, and clinically useful quantitative interpretation was also provided.

Directly Observed Treatment

Tuberkulosis adalah penyakit infeksi kronis menular yang masih merupakan masalah kesehatan masyarakat di dunia termasuk Indonesia. Tuberkulosis (TB) sebagian besar akan mengalami penyembuhan dengan pengobatan. Namun tidak semua penyakit TB sembuh dengan pengobatan. Hal ini disebabkan pengobatan dari TB yang belum terlaksana dengan baik sehingga dapat pula menyebabkan terjadinya resistensi terhadap Obat Anti Tuberkulosis (OAT), berupa Multidrug Resistant Tuberkulosis (MDR TB) dan Extensively Drug Resistant Tuberculosis (XDR TB). XDR TB adalah TB yang disebabkan oleh strain yang resistensi terhadap isoniazid dan rifampisin, disertai resisten terhadap salah satu fluorokuinolon dan salah satu dari tiga obat injeksi lini kedua (amikasin, kapreomisin atau kanamisin). XDR TB diperkenalkan tahun 2006 ketika terjadi epidemi yang sangat fatal di Afrika Selatan. XDR-TB dapat ditularkan melalui bakteri yang disebarkan oleh orang yang sudah terkena resistensi obat. Diagnosis XDR-TB ditegakkan dengan uji sensitiviti obat atau Drug Susceptibility Testing (DST), bukan sekedar berdasarkan gambaran foto toraks dan adanya faktor resiko yang ada pada seseorang. WHO telah merancang strategi Directly Observed Treatment Short Course (DOTS-Plus) untuk mengelola TB M/XDR di negara-negara miskin sumber daya. Revisi National Tuberculosis Programme (RNTCP) di bawah DOTS-Plus akan menggunakan rejimen pengobatan standar (STR) kategori IV, yang terdiri dari 6 obat (kanamisin, levofloxacin, etionamid, sikloserin, pirazinamid, dan etambutol) selama 6-9 bulan fase intensif dan 4 obat (levofloxacin, ethionamide, cycloserine, dan ethambutol) selama 18 bulan dari fase lanjutan. Penyembuhan tergantung pada tingkat resistensi obat, tingkat keparahan penyakit dan apakah sistem kekebalan pasien terganggu.

This paper describes the results of second-line drug (SLD) susceptibility tests among multidrug-resistant tuberculosis (MDR TB) cases reported in 20 European countries aiming to identify extensively drug-resistant tuberculosis (XDR TB) cases. A project on molecular surveillance of MDR TB cases was conducted by EuroTB and the National Institute for Public Health and the Environment (RIVM) from 2005 to 2007. Information on drug susceptibility testing (DST) was provided to this project and case-based data on MDR TB cases were reported on a quarterly basis by 20 countries of the World Health Organization’s European Region, including 15 European Union Member States. Data included SLD susceptibility test results, enabling a retrospective description of XDR TB cases notified between 2003 and 2007 .In 18 countries DST was performed for two or more of the SLD included in the XDR TB definition. The proportion of MDR TB isolates tested for SLD varied widely between countries (range 20 to 100 percent). In the 18 countries, 149 (10%) XDR TB cases were reported among MDR TB cases with available DST results for SLD. Sixteen additional MDR TB cases were reported by the MDR TB surveillance system when compared with the number of routinely reported MDR TB cases to EuroTB in ten countries with representative data reported during three consecutive years (2003-2005). To counter the threat of XDR TB in Europe, a standardised approach to XDR TB surveillance and DST for SLD is needed, as well as increased laboratory capacity across European countries.

Epidemiological Characteristics

Abstract Background: The aim of this study was to investigate the epidemiological characteristics and profile of drug-resistant tuberculosis (DR-TB) among children with TB in Sichuan province of China.Methods: From January 2015 to December 2018, microbiological culture-confirmed child TB cases (aged<15 years old) were enrolled retrospectively. Epidemiological and clinical information from these cases, and the drug susceptibility testing (DST) results of the isolates were collected and analyzed.Results: Of 317 culture-confirmed child TB cases, 16.7% (53/317) were aged under 5 years old. 54.9% were Tibetans, and 31.9% had clear history of contact with TB patients. More than half (53.9%) weren’t vaccinated by Calmette–Guérin bacillus (BCG). 30% (n=95) were diagnosed as severe TB, and 92.4% (n=293) were new cases. The ratio of severe TB in BCG vaccinated group was significant lower than that observed in unvaccinated group (p<0.01). Significantly higher proportion of severe TB among Tibetans than Han child TB cases was observed in BCG unvaccinated group (p<0.01). The overall rate of DR-TB in this study was 24.3% (77/317) and 17 multidrug-resistant tuberculosis (MDR-TB) cases were identified with rate of MDR-TB at 5.4% (17/317). No XDR case was found. 13 out of 17 MDR-TB cases (76.4%) were Tibetan children. The ratio of any resistance to four first-line drugs identified were: INH, 15.5%; RIF, 9.1%; EMB, 0.6% and SM, 6.0%, respectively. More than half of MDR patterns were resistant to INH+RIF (9/17), followed by at least resistance to INH+RIF+SM (n=7). Conclusions: This was the first investigation on the epidemiological characteristics and profiles of DR-TB among child TB cases in Southwest of China. Our findings indicated a potentially high risk of TB infection to Tibetan children in the concentrated Tibetan communities of Sichuan.
