Patients were prospectively followed for possible future exacerbations. Serum fibrinogen, C\u2010reactive protein (CRP), soluble urokinase\u2010type plasminogen activator receptor (suPAR) and Plasminogen activator inhibitor\u20101 (PAI\u20101) levels were studied during exacerbation and stable periods.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eighty\u2010seven patients were included and (85\u00a0M, 2 F), mean aged was 68.1\u00a0\u00b1\u00a09 (46\u201087). HRCT confirmed bronchiectasis in 38 (43.7%) patients, most commonly in tubular form (89.4%) and in lower lobes. COPD\u2010B(+) group had lower body mass index (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.036), more advanced stage of disease (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.004) and more frequent exacerbation (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.01).

Identifying of COPD\u2010B(+) phenotype by HRCT scoring systems has considerable importance for both therapeutic options and clinical outcome of the disease. In addition to fibrinogen and CRP, high serum levels of suPAR and PAI\u20101 suggest us their significant roles in increased systemic inflammation associated with coexisting of COPD and
