Item Open Access Evidence of mycobacterial disease in COPD patients with lung volume reduction surgery; the importance of histological assessment of specimens: a cohort study(Springer Nature, 2014-08-02) Char, A.; Hopkinson, N. S.; Hansell, D. M.; Nicholson, Andrew; Shaw, E. C.; Clark, S. J.; Sedgwick, P.; Wilson, Robert; Jordan, S.; Loebinger, M. R.Background Patients with COPD are at risk of non-tuberculous mycobacterial infection (NTM). This study examined the histology of lung tissue from COPD patients following lung volume reduction with particular focus on evidence of mycobacterial infection. Methods Retrospective histological study of 142 consecutive lung volume reduction surgical specimens (126 separate patients) at Royal Brompton Hospital between 2000 – 2013, with prospectively collected preoperative data on exacerbation rate, lung function and body mass index. Results 92% of patients had at least one other histological diagnosis in addition to emphysema. 10% of specimens had histological evidence of mycobacterial infection, one with co-existent aspergilloma. Mycobacteria were only identified in those patients with granulomas that were necrotising. These patients had higher exacerbation rates, lower TLCO and FEV1. Conclusion A proportion of severe COPD patients will have evidence of mycobacterial infection despite lack of clinical and radiological suspicion. This may have implications for long-term management of these patientsItem Metadata only Student attitudes towards anatomy teaching and learning in a multiprofessional context(Blackwell Publishing Ltd, 2004) Mitchell, B.
