AB  - Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) frequently occurs in patients assessed as low-risk for developing CSA-AKI. Neutrophil GelatinaseAssociated Lipocalin (N G AL), Kidney Injury Molecule-1 (KIM-1) and lactate are promising biomarkers of CSA-AKI but have not yet been explored in low-risk patients. Aim: To evaluate urinary N G AL (uNGAL), KIM-1 and lactate as biomarkers of CSA-AKI in patients with low-risk for developing CSA-AKI. Methods: This prospective, observational study included 100 adult elective cardiac surgery patients assessed as lowrisk for developing CSA-AKI. u NGAL, KIM-1 and lactate were measured preoperatively, at the end of cardiopulmonary bypass (CPB) and 3, 12, 24 and 48 h later. Results: Fifteen patients developed CSA-AKI. Patients with CSA-AKI had significantly higher lactate but similar uN G A L and KIM-1 levels compared to patients without CSA-AKI. Unlike uN G A L and KIM-1, postoperative lactate was good biomarker of CSA-AKI with the highest odds ratio (OR) 2.7 [1.4-4.9] 24 h after CPB. Peak lactate concentration > 4 mmol/L carried dramatically higher risk for developing CSA-AKI (O R 6.3 [1.9-20.5]). Conclusions: Unlike uN G A L and KIM-1, postoperative lactate was significant independent predictor of CSA-AKI with the highest odds ratio 24 h after CPB.
AB  - Uvod: Akutno ostećenje bubrega nakon kardiohirurskih procedura (KH-AOB) nastaje često i kod bolesnika koji su ocenjeni kao niskorizični za nastanak KH-AOB. Neutrofilna želatinaza udružena sa lipokalinom (NGAL), bubrežni štetni molekul-1 (KIM-1) i laktat su novi biomarkeri KH-AOB ali do sada nisu ispitivani kod niskorizičnih bolesnika. Cilj: Ispitati urinarni NGAL (uNGAL), KIM-1 i laktat kao biomarkere KH-AOB kod bolesnika koji su ocenjeni kao niskorizični za nastanak KH-AOB. Metode: Ovom prospektivnom opservacionom studijom obuhvaćeno je 100 odraslih elektivnih kardiohirurških bolesnika koji su ocenjeni kao niskorizični za razvoj KH-AOB. UNGAL, KIM-1 i laktat su određivani preoperativno, na kraju kardiopulmonalnog bajpasa (KPB) kao i 3, 12, 24 i 48 sati kasnije. Rezultati: KH-AOB se razvilo kod 15 bolesnika. Bolesnici sa KH-AOB su imali značajno više vrednosti lakatata ali slične vrednosti uNGAL i KIM-1 u poređenju sa bolesnicima bez KH-AOB. Za razliku od uN GAL i KIM-1, vrednost lakatata posle operacije se pokazala kao pouzdan biomarker KH-AOB sa najvišim OR 2.7 [1,4-4,9] 24 sata nakon zavrsetka KPB. Vrednosti lakatata > 4 mmol/L su bile povezane sa dramatično povišenim rizikom za nastanak KH-AOB (O R 6,3 [1,9-20,5]). Zaključak: Za razliku od uN GAL i KIM-1, vrednosti lakata posle operacije su bile značajan nezavisni prediktor razvoja KH-AOB sa najboljom prediktivnom vrednošću 24 sata nakon završetka KPB.

AB  - INTRODUCTION: Two types of hereditary nephritis, nonprogressive and progressive, clinically present as asymptomatic haematuria, sometimes combined with proteinuria. At the onset, in both types, light microscopic changes are minimal, immunofluorescence findings are negative, and diagnosis can be made only upon electron microscopic findings that are considered to be specific. OBJECTIVE: The aim of this study was to determine the significance of Goodpasture antigen detection in diagnosis of progressive and nonprogressive hereditary nephritis in its early phase. METHOD: Analysis of renal biopsy specimens was done in patients with hereditary nephritis that were followed from 1990 to 2005. Progression of renal disease was examined in 14 patients with Alport's syndrome, 10 patients with thin basement membrane disease, and 6 patients with unclassified hereditary nephritis diagnosed. For all these cases, indirect immunofluorescence study with serum from a patient with high titer of Goodpasture autoantibodies that recognize the antigenic determinants in human glomerular and tubular basement membrane was performed. RESULTS: In 11 out of 14 cases diagnosed as Alport's syndrome, there was negative staining with Goodpasture serum, and in 3 additional cases with Alport's syndrome, expression of Goodpasture antigen in glomerular basement membrane and thin basement membrane was highly reduced. In all 10 patients with thin basement membrane disease, immunofluorescence showed intensive, bright linear staining with Goodpasture serum along glomerular and tubular basement membrane. In 2 out of 6 patients with unclassified hereditary nephritis, Goodpasture antigen expression was very strong, in one patient it was very reduced, and in 3 patients it was negative. CONCLUSION: The results of our study show that Goodpasture antigen detection plays a very important role in differential diagnosis of progressive and nonpregressive hereditary nephritis, particularly in early phases of the disease.
