| Summary: | Aim. To determine the risk factors and diagnostic value of urinary N-terminal probrain natriuretic peptide (NT-proBNP) for verification of heart failure in human immunodeficiency virus (HIV)-infected patientsMaterial and methods. This cross-sectional screening clinical trial included 115 HIV-infected patients who were hospitalized during 24 months. The patients were divided into 2 groups, depending on the data suggestive of HF and the blood and urinary NT-proBNP concentration. So, group 1 included 69 HIV-infected patients with HF symptoms and increased blood and urinary NTproBNP, while group 2 — 46 HIV-infected patients not meeting HF criteria. NTproBNP concentration was determined on Immulite 1000 Immunoassay System (DPC, USA) in blood plasma and frozen urine using Vector Best reagents (Russia).Results. Correlation analysis revealed a significant direct moderate correlation between blood and urinary NT-proBNP in the entire cohort of studied patients (r=0,367; p<0,05). Urinary NT-proBNP ≥8,6 pg/ml ml is diagnostic for HF verification in HIV-infected patients. Significant differences between the groups were obtained in the incidence of ventricular arrhythmias, viral hepatitis B and C, liver cirrhosis, infective endocarditis, other inflammatory diseases, thrombocytopenia, left ventricular (LV) diastolic dysfunction and its severity. In addition, there were differences in LV mass index, left atrial volume index, incidence of LV hypertrophy and left atrial enlargement, concentration of hemoglobin and CD4 cells <200 in 1 µl. The preserved LV ejection fraction was detected significantly more often (p<0,001). Conclusion. In HIV-infected patients, blood plasma and urinary NT-proBNP concentration correlates with each other. Urinary NT-proBNP ≥8,6 pg/ml is diagnostic for HF verification in HIV-infected patients. Risk factors and features of developing HF, estimated by NT-proBNP concentration in frozen urine in HIV-infected patients, are comparable to data obtained from blood plasma NTproBNP. |
