PELOD score is a tool which is used to characterize severity of organ dysfunction in critically ill child. Score which is given to each organ will increase according the severity of organ dysfunction so PELOD score can be used to predict severity of organ dysfunction. The PELOD scoring system consists of physical and laboratory variables representing 6 organs, namely nervous, cardiovascular,

renal, respiratory, hematologic, and hepatic system [17]. Value of PELOD 12 was taken as the average of the whole set. Specimens for the diagnosis of infection were obtained Palbociclib molecular weight as early as possible. Complete medical history and clinical examination, laboratory parameters, and disease-specific examinations were evaluated. Blood samples were obtained from a central venous catheter during the first 12 h after the diagnosis SIRS or septic state, or at the beginning of surgery in the control group. For the evaluation of clusterin dynamics, samples

were collected at all times when patients meet the criteria SIRS or septic state. Samples were allowed to clot at room temperature and were centrifuged at 3000 rpm for 10 min. Separated serum was stored at −80 °C until further analysis. Samples were measured by enzyme immunoassay for the quantitative measurement (BioVendor, Laboratorní medicína a.s., Brno, Czech Republic). Samples were incubated in microplate wells pre-coated with monoclonal anti-human clusterin antibody. After 60 min incubation and washing, biotin labeled LBH589 second monoclonal anti-human clusterin antibody was added and incubated with captured clusterin for 60 min. After another washing, streptavidin-HRP conjugate was added. After 30 min incubation and the last washing step, the remaining conjugate was allowed to react with the substrate C-X-C chemokine receptor type 7 (CXCR-7) solution (TMB).

The reaction was stopped by addition of acidic solution and absorbance of the resulting yellow product was measured. The absorbance is proportional to the concentration of clusterin. The laboratory technicians performing the assays were completely blinded to the clinical information. Baseline levels of analyzed protein and demographic characteristics were summarized using descriptive statistics (N, mean, standard deviation, median, minimum, maximum). The analysis was performed on logarithmically transformed data to achieve an approximately normal distribution of the evaluated data. The dynamics (kinetics) of the protein levels during the period of SIRS or septic state were analyzed using the analysis of variance (ANOVA). Correlation of values in the patients was performed using a symmetric covariance matrix (the type of compound symmetry). Significance of difference in dynamics between analyzed groups is indicated by p-value of group and time interaction effect. ROC analysis was performed to determine the discriminatory characteristics of the protein values.
