Abstract Abstract 3807 Background: The prognostic role of serum ferritin (SF) evaluation at baseline in patients (pts) affected by myelodysplastic syndrome (MDS) is still controversial. In fact, increased SF mainly due to transfusion requirement during disease history has a clear negative impact on overall survival (OS) (Malcovati et al., 2006) and also on leukemic evolution (LE) (Sanz, ASH 2008, de Swart ASH 2010) while contrasting data about its role at baseline on OS has been published. Park and colleagues (ASH 2010) failed to identify a negative prognostic impact of SF higher than 300 ng/mL in a cohort of low risk untransfused MDS patients while data from the European LeukemiaNet MDS registry identified SF as an independent prognostic factor for OS and progression-free survival in low- and int-1 MDS (de Swart, Edimburgh 2011). SF can be a marker of iron overload but also of inflammation and little is known about the impact on survival of other iron parameters such as transferrin saturation (TS) or inflammation such as C reactive protein (CRP) in MDS pts at diagnosis. Aim: Aim of our study was to evaluate the prognostic role of iron parameters and inflammation at diagnosis in MDS patients analyzing data collected in the MDS Piedmont Registry. Materials and methods: 1360 patients enrolled in the MDS Piedmont Registry (1999–2010) were analyzed. Patients with information on OS and LE and available baseline SF (n=670), TS (n=299), CRP (n=287) were included in the analysis. Survival analysis was performed using Kaplan-Meier method. Patients were stratified according to a cut off value of 800 ng/mL for SF, 40% for TS and values within or higher the normal range (0,8 mg/dL) for CRP. In order to compare survival curves, log-rank test was used. Cumulative incidence of LE, according to SF, TS and CRP levels, was calculated accounting for death from any causes as a competing event. Results: In the population with SF baseline values, 3-years OS in pts with SF < 800 ng/mL was 80.7 (95%CI: 75.8–84.8) and in pts with SF >800 ng/mL was 66.1 (95%CI: 46.7–79.8) (p= 0,006). The result seems to be confirmed in the low risk MDS subgroup in toto (n=226) and considering only the untransfused pts (136 cases) (p=0,0073 and p=0,0038 respectively) but no statistically significance in OS of high risk pts (n=108) has been observed. In subjects with available data on TS, 3-years OS for pts with TS lower than 40% was 75.0 (95% CI: 64.2–83.0) while in pts higher than 40% was 72.1 (95%CI: 59.5–81.4) (p=0,1). Finally, in pts with CRP values 3-years OS was 80.8 (95%CI: 69.7–88.2) for patients < 0,8 mg/dL and 47.2 (95%CI: 34.5–58.9) for pts > 0,8 mg/dL. Also 3-year cumulative incidence of LE was higher in pts with SF > 800 ng/mL [35.8 (95%CI: 20.3–51.2) vs 18.5 (95%CI: 14.4–22.5); p=0,002 ] and in those with CPR > 0,8 mg/dL [35.3 (95%CI: 23.9–46.7) vs 12.7 (95%CI: 5.7–19.7); p<0,001]. In TS subgroups no difference was observed [13.5 (95%CI: 7.0–20.0) for TS<40% vs 20.8 (95%CI: 11.8–29.8) for TS>40%; p=0.172]. Conclusions: although the limits of missing data, our results suggest that high levels of SF and CRP above the normal range at baseline should have a prognostic role in MDS pts, while TS seems to have little impact on OS. Moreover SF and CRP seem to have both a negative impact on LE. Our data suggest a more important prognostic role of chronic inflammation parameters than iron overload or oxidative stress in MDS patients at diagnosis. Further prospective evaluation of more specific parameter of oxidative stress and inflammation need to be analyzed in order to confirm our preliminary observation. Disclosures: No relevant conflicts of interest to declare.

SummaryBackground:The objective here is to examine the role of overall oxidative stress in the etiopathogenesis of gluten-sensitive enteropathy disease and its relationship with gluten free diet and autoantibodies.Methods:Eighty gluten-sensitive enteropathy patients and 80 control group participants were included in the study. As oxidative stress parameters, we researched total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), paraoxonase-1 and arylesterase parameters in the serum samples of gluten-sensitive enteropathy patients.Results:In comparison to the control group, gluten-sensitive enteropathy patients had lower TAS, paraoxonase-1 and arylesterase levels and gluten-sensitive enteropathy patients had considerable TOS and OSI levels. In contrast, patients who agreed to the gluten free eating routine had a higher OSI proportion and patients who did not conform to the gluten free eating regimen had a lower paraoxonase-1 level. An affirming reciprocation was de tected amidst TOS and OSI proportion and gluten-sensitive enteropathy autoantibodies and C-reactive protein levels and a negative correlation was found between arylesterase level and gluten-sensitive enteropathy autoantibodies.Conclusions:We observed oxidative stress levels to be higher in gluten-sensitive enteropathy patients contrasted with the control group. Oxidative stress level showed differences in gluten-sensitive enteropathy patients depending on gluten diet content and autoantibody positivity. In point of fact, C-reactive protein and gluten-sensitive enteropathy autoantibodies are identified with oxidative anxiety parameters resulting in the possibility that oxidative stress might be successful in the gluten-sensitive enteropathy pathogenesis.

Based on the role of oxidative stress in the pathophysiological mechanisms of sepsis and the importance of PCT as a clinically applicable biomarker for early detection of inflammatory response initiation, we aimed this study at examining the correlation between PCT levels and oxidative stress parameters (prooxidants and antioxidants) in patients with sepsis. This study was designed as a case-series prospective clinical study which involved 103 critically ill patients and 17 healthy participants with diagnosis of sepsis/septic shock (over 18 years of age, both gender) admitted to the Intensive Care Unit (ICU) of Valjevo General Hospital in Serbia. All subjects were divided into patients who were operated on/underwent surgery before sampling and have sepsis (n=24), patients who were operated on/underwent surgery before sampling and have septic shock (n=25), patients who were not operated on/did not undergo surgery before sampling and have sepsis (n=26), patients who were not operated on/did not undergo surgery before sampling and have septic shock (n=28), and participants who are healthy (n=17). PCT has confirmed a positive correlation with prooxidants and type of critical illness, and performing surgical intervention diminished oxidative stress in patients with septic shock. Prognosis in critically ill patients was strongly associated with PCT levels but not with nonspecifically C-reactive protein.
