ABSTRACT

Objective/Background: drug-resistant strains of tuberculosis [TB] represent a major threat to global TB control. In low- and middle-income countries, resource constraints make it difficult to identify and monitor cases of resistance using drug susceptibility testing and culture. Molecular assays such as the GeneXpert Mycobacterium tuberculosis/rifampicin may prove to be a cost-effective solution to this problem in these settings. The objective of this study is to evaluate the use of GeneXpert in the diagnosis of pulmonary TB since it was introduced into two tertiary hospitals in Ghana in 2013


Methods: a 2-year retrospective audit of clinical cases involving patients who presented with clinically suspected TB or documented TB not improving on standard therapy and had samples sent for GeneXpert testing


Results: GeneXpert identified 169 cases of TB, including 17 cases of rifampicin-resistant TB. Of the seven cases with final culture and drug susceptibility testing results, six demonstrated further drug resistance and five of these were multidrug-resistant TB


Conclusion: these findings call for a scale-up of TB control in Ghana and provide evidence that the expansion of GeneXpert may be an optimal means to improve case finding and guide treatment of drug-resistant TB in this setting

ABSTRACT

Aspergillomas are often misdiagnosed as tuberculosis [TB] in developing countries where the prevalence of TB is high, hemoptysis is often equated with TB, and most patients are diagnosed clinically. This report describes the case of a patient being treated for smearnegative TB who presented with hemoptysis and was found to have an aspergilloma
