An incidental finding of chronic lymphocytic leukaemia in a patient with pulmonary tuberculosis.

Victoria R Parker, Jaclyn A Bennet, Ian M Sanne,

In this case report, we described a 48-year-old human immunodeficiency virus-negative man with pulmonary tuberculosis (TB) who had an incidental finding of concurrent chronic lymphocytic leukaemia. We highlighted the importance of considering other differential diagnoses when patients present with TB or haematological malignancies. We also discussed the difficulties in diagnosis ...

Does Disseminated Nontuberculous Mycobacterial Disease Cause False-Positive Determine TB-LAM Lateral Flow Assay Results? A Retrospective Review.

Jeremy S Nel, Christopher K Lippincott, Rebecca Berhanu, David C Spencer, Ian M Sanne, Prudence Ive,

We retrospectively reviewed the Determine TB-LAM lateral flow assay (LF-LAM) results among human immunodeficiency virus-infected patients with disseminated nontuberculous mycobacterial (NTM) disease. LF-LAM was positive in 19 of 21 patients without evidence of tuberculosis (TB) coinfection. Although TB-NTM coinfection may have been underdiagnosed, our results suggest that disseminated NTM disease ... Read more >>

<h4>Background</h4>Recurrence of tuberculosis after treatment makes management difficult and is a key factor for determining treatment efficacy. Two processes can cause recurrence: relapse of the primary infection or re-infection with an exogenous strain. Although re-infection can and does occur, its importance to tuberculosis epidemiology and its biological basis is still ... Read more >>
