Below: Overall drug resistance (%) in TB patients with and without COPD
Below: ROC curve to assess the discriminatory ability of the model predicting MDR-TB in patients with COPD
A total of 2164 patients aged ≥ 40 years with available results of drug susceptibility test (DST) and medical records were screened for this study: 268 patients with discharge diagnosis of COPD and 1896 patients without COPD. Overall, 14.2% of patients with COPD and 8.5% patients without COPD were MDR-TB. The rate of MDR-TB were significantly higher in patients with COPD (P<0.05). Migrant (odds ratios (OR) 1.32, 95% confidence interval (CI) 1.02–1.72), previous anti-TB treatment (OR 4.58, 95% CI 1.69–12.42), cavity (OR 2.33, 95% CI 1.14–4.75), and GOLD stage (OR 1.86, 95% CI 1.01–2.93) were the independent predictors for MDR-TB among patients with COPD.
MDR-TB occurs more frequently in patients with underlying COPD, especially those with being migrant, previous anti-TB therapy, cavity and severe airway obstruction.
