Opis:
Serum concentrations of advanced oxidation protein products (AOPPs) and glycation end products (AGEs) were assessed with respect to functional compromise of liver, as determined by the Child-Pugh and MELD scores. Patients with decompensated liver cirrhosis (Child-Pugh B and C) exhibited significantly higher serum concentrations of AOPPs than both patients with compensated liver cirrhosis (Child-Pugh A) and controls. The levels of plasma AGEs in all liver cirrhotic patients were higher when compared with those with the controls and this difference was statistically significant. Plasma total antioxidant status of the patients was significantly lower than that of controls. Significant positive correlations between AOPPs level and the MELD score and between the oxidative stress index and the MELD score were found in all patients with liver cirrhosis. Altered AOPPs levels in decompensated patients may influence the potency of oxidative stress and the progression of liver disease.

Opis:
Advanced oxidation protein products (AOPPs) are protein markers of oxidative stress with pro-inflammatory properties that accumulated in liver cirrhosis. In the present study, we investigated the association between chronic inflammatory response triggered by AOPPs and the severity of liver disease as assessed by the Child-Pugh score. Plasma concentrations of AOPPs and inflammatory markers such as C-reactive protein, tumor necrosis factor-α, and interleukin-6 were measured in 41 patients with HCV-related cirrhosis, 43 patients with alcohol-related liver cirrhosis (ALC), and in 30 age and sex matched controls. In comparison with controls, AOPPs were increased in HCV-related compensated (Child-Pugh A) and decompensated (Child-Pugh B-C) cirrhosis and in alcohol-related compensated cirrhosis. AOPPs level positively correlated with Child-Pugh score in alcohol-related cirrhosis but not in HCV-related cirrhosis and the correlation with the indices of chronic inflammation was stronger in ALC. In turn, AOPPs in HCV-related cirrhosis was related to inflammation to a lesser extent, but a significant correlation with antioxidant defense could be noted. In summary, liver cirrhosis was associated with increased formation of AOPPs, which differed between alcohol-related and HCV-related cirrhosis with respect to the relationship between AOPPs and antioxidant defense, stage of liver cirrhosis, and inflammatory response. The significant correlation between AOPPs accumulation and indices of chronic inflammation, more specifically TNF-α, suggests that oxidative stress may be a mediator of chronic inflammatory state in the early stage of alcohol-related cirrhosis.

Opis:
Introduction. The main mediators of the sympathetic nervous system in the effectors part are catecholamines (CA). An increased sympathetic nerve activity observed in chronic kidney disease (CKD), is due to a raised level of CA in plasma. Renalase is a protein secreted by the kidneys, composed of 342 amino acids, which is able to metabolize the circulating CA and possibly play an important role in the regulation of sympathetic tone and blood pressure. Also, oxidative stress, defined as a disruption of the equilibrium between the generation of oxidants, is a crucial factor in the development of the inflammatory syndrome associated with CKD. The advanced oxidation protein products (AOPP) represent exquisite markers of phagocyte-derived oxidative stress. Objective. The aim of the study was to investigate the concentration of renalase and explore the associations between AOPP with regards to CA in haemodialysis (HD) patients. Materials and method. The study was conducted among 50 residents of the municipality and neighbouring villages in the province of Lublin, central-eastern Poland. Results. In the studied patients, it was found that an average concentration of renalase was 44.8 ± 6.5 μg/mL, whereas of AOPP plasma levels – 57.5 ± 21.5 μmol/L. The results demonstrated the correlation between levels of renalase and AOPP in the HD patients. Indeed, elevated levels of renalase and AOPP in HD may be due to the presence of uremic toxins in blood. The concentration of urea affects the plasma concentrations of AOPP and renalase causing a direct relationship between renalase and AOPP. However, there is no clear relationship between renalase and circulating catecholamines in HD patients.
