Effect of erythropoietin and its combination with hypoxic altitude chamber training on the clinical and functional manifestations of chronic glomerulonephritis
Abstract
AIM. To evaluate the efficiency of treatment for renal anemia in patients with chronic glomerulonephritis (CGN), by using erythropoietin and its combination with hypoxic altitude chamber training (HACT). MATERIALS AND METHODS. Sixty-three patients (41 men and 22 women) (mean age 37.1±13.3 years) with CGN during the predialysis phase of chronic kidney disease (CKD) complicated by anemia. Hemoglobin (Hb), packed cell volume (PCV), and red blood cell indices (mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC)), platelet count, serum iron, fibrinogen, C-reactive protein (CRP) and creatinine levels were determined in all the patients at baseline and during a prospective follow-up. Glomerular filtration rate (GFR) was measured using with the Rehberg-Tareev test. Along with standard renal protective therapy, all the patients received either epoetin beta (n=31; Group 1) or its combination with HACT (n=32; Group 2). In Group 1 patients (n=31), erythropoietin (EPO) was given in an initial dose of 20-50 IU/kg thrice daily, followed by the dose being adjusted until the target Hb level was reached. Group 2 patients (n=32) received HACT cycles by the standard procedure in combination with EPO given in lower doses (20-50 IU/kg once weekly). A prospective follow-up of the patients was carried out during one year. RESULTS. Following one year, the number of patients who had achieved the target Hb level was 74.1% in Group 1 and 87.5% in Group 2. Over time, there were increases in the concentration of Hb (from 108.6±19.4 to 124.5±14.09 g/l; p
