Abstract
Multidrug-resistant tuberculosis (MDR-TB) defined as TB caused by strains of Mycobacterium tuberculosis that are resistant to at least isoniazid and rifampicin.
The aim of this paper was to describe the resistance patterns of MDR-TB in FB&H.
Material and methods: Retrospective analysis of the reported cases with MDR-TB in FB&H during ten years (2000-2009) notified through drug susceptibility testing (DST) in 5 laboratories according to the recommendation of the WHO and IUATLD in Europe.
Results: Total cases with DST results: 1034 (never treated 913; previously treated 121) in 2000;1184 (1054;129) in 2001; 1036 (936;100) in 2002; 1042 (951;91) in 2003; 1125 (1048; 77) in 2004; 769 (692;77) in 2005; 908 (827;81) in 2006; 951 (847;104) in 2007; 518 (471;47) in 2008; 581 (529;52) in 2009.
MDR-TB among never-treated cases: 1 (0.11%) in 2000; 2 (0.19%) in 2001; 4 (0.42%) in 2002; 1 (0.10%) in 2003; 4 (0.38%) in 2004; 4 (0.57%) in 2005; 2 (0.24%) in 2006; 7 (0.82%) in 2007; 3 (0.63%) in 2008; 0 (0.0%) in 2009.
MDR-TB among previously-treated cases: 2 (1.65%) in 2000; 7 (5.42%) in 2001; 9 (9.0%) in 2002; 1 (1.09%) in 2003; 6 (7.79%) in 2004; 5 (6.49%) in 2005; 3 (3.70%) in 2006; 10 (9.61%) in 2007; 9 (19.14%) in 2008; 1 (1.92%) in 2009.
Conclusion: Data from FB&H show relatively low prevalences of MDR-TB during ten years.The prevalence of MDR-TB remains low at 0.57% - 0.82% among newly detected cases and 9.61% - 19.14% among previously detected cases.Recent data also indicate a further desrease in MDR-TB. This decrease may likely be the result of well implemented DOTS.Establishing reference laboratory facilities with adequate capacity to supervise DST and surveillance activities in the country is a critical step in MDR-TB control and care.
