RESUMO
Singapore has experienced a rise in the tuberculosis (TB) incidence rate among her local population since 2008, which we believe, is contributed in no small part to a recent increase in community transmission due to delayed diagnosis of infectious pulmonary TB cases. Data from the TB notification registry showed an increase from 2004 to 2008 in the number and proportion of sputum acid-fast bacilli smear-positive pulmonary TB cases with prolonged cough. Two surveys at the TB Control Unit showed that healthcare system delays exceeded patient delay in seeking medical consultation. There is thus an urgent need to heighten TB awareness among the public and the medical community in order to reduce the time taken to diagnose infectious TB cases in Singapore.

INTRODUCTION: Extensively drug-resistant tuberculosis (XDR-TB) is an emerging global health risk. We present the first case report of XDR-TB in Singapore. CLINICAL PICTURE: A 41-year-old Indonesian lady with previously treated pulmonary tuberculosis presented with chronic cough. Her sputum was strongly acid-fast bacilli positive and grew Mycobacterium tuberculosis complex resistant to first and second-line TB medications. TREATMENT: She received 5 months of intensive multidrug treatment without sputum smear conversion. She then underwent resection of the diseased lung. The total cost incurred amounted to over S$100,000. OUTCOME: She achieved sputum smear/culture conversion post-surgery, but will require further medical therapy for at least 18 months. CONCLUSION: XDRTB is poorly responsive to therapy and extremely expensive to manage. Its prevention by strict compliance to therapy is paramount.
