Abstrakt: C-reactive protein (CRP) and leukocyte count are standard tools for recognising inflammation in COPD patients. This study aimed to find if there is a pattern in monocyte related haematological indices - monocyte to neutrophil ratio (MNR) and monocyte to lymphocyte ratio (MLR) - which could be helpful in differentiating COPD patients in need for hospitalization due to acute exacerbation of COPD or differentiating frequent COPD exacerbators from non-frequent COPD exacerbators. The study included 119 patients with COPD and 35 control subjects, recruited at the Clinic for Respiratory Diseases Jordanovac, University Hospital Centre Zagreb, Croatia. Complete blood count was performed on Sysmex XN-1000, CRP on Cobas c501, and Fbg on BCS XP analyser. Data were analysed with MedCalc statistical software. The COPD patients were divided into three groups - frequent exacerbators (FE), non-frequent exacerbators (NFE), patients hospitalized for acute COPD exacerbations (HAE) and the control group were healthy smokers (HS). A statistically significant difference was found in the values of MNR while comparing these groups of patients: FE vs HAE (p<0.000), NFE vs HAE (p<0.000) and HS vs HAE (p<0.001); and for the values of MLR: FE vs HAE (p<0.022), NFE vs HAE (p<0.000) and HS vs HAE (p<0.000). As MLR and MNR have shown the statistical difference comparing the group of HAE to NFE, FE and HS, MLR and MNR could be valuable and available markers of acute COPD exacerbations and need for hospitalization.
