Anemia is common in patients with chronic kidney disease (CKD) and contributes to cardiovascular alterations. Recent findings suggest that B-type natriuretic peptide (BNP) is a sensitive biomarker for left ventricular dysfunction, but relationship between hemoglobin and BNP in CKD patients is unclear. Hemoglobin, plasma BNP and serum creatinine levels were measured in 49 patients with CKD (without heart failure), divided in two groups according to the hemoglobin status (cut-off point 110 g/L). All patients underwent echocardiography in order to assess left ventricular (LV) morphology and function. The results showed that in the group of patients with hemoglobin levels under 110 g/L BNP levels were significantly elevated (p < 0.001), as well as left ventricular mass index (p < 0.001). Systolic and diastolic LV function were significantly better in patients with hemoglobin levels above 110 g/L (p < 0.001). Hemoglobin levels were inversely related to BNP values (r = -0.451, p < 0.001). Significantly negative correlation between BNP level and creatinine clearance (p = 0.009), and significantly positive correlation between BNP level and left ventricular mass index (LVMI) were established. A similar but positive relationship was observed between hemoglobin levels and creatinine clearance (p < 0.01). We established statistically significant negative correlation between hemoglobin levels and LVMI (r = -0.564, p < 0.001). In conclusion, BNP and hemoglobin levels depend on the renal function. Anemia may contribute to elevated BNP levels in CKD patients, and may represent an important confounder of the relationship between BNP and cardiac alteration in these patients.

The aim of this retrospective study was to evaluate the results of the immunosuppressive regiment in managing of IgA nephropathy associated with primary nephrotic syndrome at the Nephrology Clinic, University of Sarajevo Clinics Centre in period of 1997-2007. We studied 19 patients (4 women and 15 men) with idiopathic nephrotic syndrome, where pathomorphologic changes of IgA nephropathy were proved by kidney biopsy. The levels of diuresis, proteinuria, albuminemia, lipidemia and kidney function, as measure of efficiency of used therapy, were monitored. The IgA nephropathy present with the nephrotic syndrome was shown in 15.8% (19) patients underwent renal biopsy due to primary nephrotic syndrome in the period of observation. The average age of patients with IgA nephropathy was 34.9+/-14.1 years. Eight patients from this group were treated with corticosteroid therapy (1-1.5 mg/kg of body weight for 4 weeks, followed by 0.5 mg/ kg of body weight until therapeutic response was achieved, and finally gradual exclusion of therapy after eight weeks in responsive patients), 6 patients with corticosteroids and bolus cyclophosphamide (10-15 mg/kg BW), and in 5/19 patients cyclosporine therapy was used (3 mg/kg BW). Complete remission of nephrotic syndrome was achieved in 42.1% of the patients. In conclusion, in adults patients with primary nephrotic syndrome associated with IgA nephropathy, used immunosuppressive therapy resulted in a high percentage of achieved remissions.

Strict therapy protocol, which would be used universally for certain morphological forms of primary nephrotic syndrome, does not exist. The aim of the study was to show the effects of used therapy protocol in treatment of primary nephrotic syndrome at the Institute of Nephrology, Clinical Center University of Sarajevo in period of 2000-2005. The retrospective analysis covered 48 patients (17 women and 31 men) with idiopathic nephrotic syndrome, where pathomorphological changes were proved by kidney biopsy. Minimal change disease was confirmed with 6 (12.5%) patients. All patients were initially treated with corticosteroids with dose of 1 mg/kg of body weight. Five patients were in the group of primary responders (83.3%) with long term total remission, and 1 patient (16.6%) was a primary responder with 3 relapses in 8 months with a therapy of corticosteroids and bolus of cyclophosphamide. Diffuse mesangial proliferative glomerulonephritis was shown in 13 patients (27.1%). Seven patients from this group were treated with corticosteroid therapy (1 mg/kg of body weight for 4 weeks, followed by 0.5 mg/ kg of body weight until therapeutical response was achieved, and finally gradual exclusion of therapy after eight weeks in responsive patients). Six patients were treated with corticosteroids and one-month of bolus cyclophosphamide during half of year (10-5 mg/kg of body weight). Total remission was achieved in 37,9% of the patients. The IgA nephropathy presented with the nephrotic syndrome was shown in 10.4% (5) of the patients. Three patients from this group were treated with corticosteroid therapy (1 mg/kg of body weight for 4 weeks, followed by 0,5 mg/ kg of body weight until therapeutical response was achieved, and finally gradual exclusion of therapy after eight weeks in responsive patients) and.2 patients with corticosteroids and cyclophosphamide (1.5 mg/kg of body weight) during 6 months. Complete remission of nephrotic syndrome from this pathomorphological category was achieved in 2 patients. Membranoproliferative glomerulonephritis was shown in 6 patients (12.5%). All were treated with corticosteroids plus bolus of cyclophosphamide. Partial remission was achieved in one patient. Membranous glomerulonephritis was confirmed in 18 patients (37.5 %). Combined therapy of corticosteroids and bolus of cyclophosphamide was used in 7/18 patients, in 2/18 patients therapy of corticosteroids and per os cyclophosphamide (2 mg/kg of body weight) and in 9/18 patients cyclosporine therapy (3 mg/kg of body weight). Complete remission was achieved in 38.8% of the patients. A high percentage of achieved remissions of primary nephrotic syndrome in adults shows the efficiency of immunomodulating therapy used. Membranoproliferative glomerulonephritis still remains a therapy problem.

Anaemia appears to play an important role in left ventricular (LV) enlargement in chronic kidney disease patients. The objective of this study was to evaluate LV echocardiography changes during anaemia correction with recombinant human erythropoietin (rHu-Epo) in chronic haemodialysis patients (HD pts) with signs of anaemia and LV hypertrophy (LVH). The study included 20 HD pts aged 39,6 +/- 5,3 yrs, with the same condition of HD treatment, anaemia and echocardiographically LVH verified. At the beginning of the rHu-Epo treatment haemoglobin (Hb) level was < 90 g/L and the target Hb level was 110 g/L. Echocardiography was performed at the beginning (baseline) and after six months of rHu-Epo treatment. LVH was defined as LV mass index >100 g/m2 in women and >131 g/m2 in men. We observed significant reduction of LV mass index (LVMI) (mean 26,4%, p=0.008), as well as LV volumen. There was a significant negative correlation between Hb level and LVMI with predictive LVMI reduction of 2,317 g/m2 for each 1g/L rising of mean Hb level. The results of the study confirm the importance of early anaemia correction in haemodialysis patients aimed to improve LV parameters.
