Biomarker NTproBNP in Patients with Severe CommunityAcquired Pneumonia
The aim of the study was to determine the correlation between blood levels of Nterminal portion of the inactive precursor of natriuretic peptide of Btype (NTproBNP) and hemodynamic, clinical and laboratory parameters in the course of intensive treatment of patients with severe communityacquired pneu...

| description | The aim of the study was to determine the correlation between blood levels of Nterminal portion of the inactive precursor of natriuretic peptide of Btype (NTproBNP) and hemodynamic, clinical and laboratory parameters in the course of intensive treatment of patients with severe communityacquired pneumonia (CAP).Materials and methods. The study included 12 patients (10 men and 2 women) with severe CAP, age 25—88 (51.5 (41.25; 69)) years. The severity of the condition was as follows (averages and percentiles): on a scale of CURB65 — 3—5 (4; 4,5) scores, APACHE II — 16—33 (23 (18.75; 25)) scores, SOFA — 6—16 (10 (9; 12.75)) points. Concentartions of NTproBNP in venous blood 24—36 h post admission and on day 5 of treatment were determined by analyzer Dimension Xpand Plus (Siemens).Results. Within 24—36 hours after the admission concentration of NTproBNP was 783.5 (460.75; 4150.25) pg/ml. The content of the biomarker remained higher than in norm in 66.7% of patients. By the 5th day the concentration of the biomarker was 537 (376.25, 1334) pg/ml. In surviving patients (66.7%), the concentration of NT proBNP was decreasing (P=0.008) to day 5 of treatment from 918 (560, 8501) to 391 (341, 1010) pg/ml. CAP patients who did not survived later (32.3%) exhibited no decrease of the biomarker concentration. Significant correlation between NTproBNP on admission to ISU and index of total peripheral vascular resistance on day 2 of intensive treatment (r=0.63; p<0.05) and day 5 (r=0.58, P<0.05) was revealed. Echocardiography systolic pulmonary artery pressure correlated with the content of NTproBNP 24—36 hours after admission to the Intensive Care Unit and on the 5th day of treatment.Conclusion. We suggested that the reason for increased concentration of NTproBNP is an overload of the right ventricle myocardium due to pulmonary hypertension as a characteristic of acute respiratory distress syndrome. |
