Chronic kidney disease in patients with chronic heart failure infected with human immunodeficiency virus

Abstract

Chronic kidney disease (CKD) is the most common manifestation of target organ damage in chronic heart failure (CHF). The aim of the study was to determine the risk factors associated with the course of CKD in patients with CHF infected with the human immunodeficiency virus (HIV). According to the results obtained, the prevalence of CKD among HIV-infected patients with CHF is 58.82%, which is 4 times more common than in patients with HIV infection without CHF. The dependence of glomerular filtration rate (GFR) on three main factors that reflect damage to the heart muscle – blood plasma NT-proBNP concentration, left ventricular ejection fraction (LVEF%) and left ventricular myocardial mass index (LVMI) was proved, which together, being included in the regression model, determine 42.2% of the variance of GFR values and are decisive in the development of CKD in patients with CHF on the background of HIV infection. The concentration of NT-proBNP in the blood plasma of patients with CHF equal to or greater than 683.65 pg/ml can be considered as a diagnostic criterion for the development of CKD in HIV-infected people with a sensitivity of the method of 75.0% and a specificity of 75.4%, respectively. In addition, risk factors for the development of CKD in patients with CHF and HIV infection are smoking, alcohol and drug use, a history of chronic and acute forms of coronary artery disease, atrial fibrillation, ventricular arrhythmias, diabetes mellitus, chronic viral hepatitis C, anemia and thrombocytopenia. Patients with CHF and CKD have a more rigid arterial wall – there is a significant excess of the stiffness indices of the aorta and peripheral arteries. Long-term use of antiplatelet agents, NRTIs, NNRTIs, and protease PIs may aggravate the course of CHF in HIV-infected people with CKD manifestations.
