Objective. Recent studies have demonstrated that enteric glial cells (EGC) participate in the homeostasis of the gastrointestinal tract. This study investigated whether enteroglial markers, including S100B protein and glial fibrillary acidic protein (GFAP), can serve as noninvasive indicators of EGC activation and disease activity in UC patients.Methods. This clinical prospective study included 35 patients with UC and 40 age- and sex-matched controls. The diagnosis of UC was based on standard clinical, radiological, endoscopic, and histological criteria. Clinical disease activity was evaluated using the Modified Truelove-Witts Severity Index. Serum samples were analyzed for human GFAP and S100B using commercial enzyme-linked immunosorbent assay kits.Results. GFAP was not detected in the serum of either UC patients or controls (P>0.05). However, we found a significant (P<0.001) decrease in the serum S100B levels in the UC patients. No correlation between the serum S100B level and the disease activity or duration was observed (P>0.05). The serum S100B levels did not differ between UC patients with active disease (24 patients, 68.6%) or in remission (11 patients, 31.4%) (P>0.05).Conclusions. Ulcerative colitis patients had significantly lower serum S100B levels, while GFAP was of no diagnostic value in UC patients.

e20042 Background: The purpose of this sub study was to identify peripheral blood biomarkers associated with the therapeutic effect of immunotherapy with dendritic cell vaccine in patients with metastatic melanoma (MM). Methods: Patients (pts) with low disease burden achieved disease control after two cycles of chemo (cisplatine, vinbalstie, DTIC) were randomized dendritic cell vaccine (DC) or three cycles of chemo. Vaccination schedule consisted of 5 subcutaneous injections of dendritic cell (DC) vaccine (2×106 cells pulsed with autologous lysate) with 14 days intervals. S100B level, LDH level, and peripheral blood lymphocytes immune phenotype were assessed before treatment, after two cycles of chemo and after each vaccination cycle. Results: 104 pts were included in the study, 30 pts were randomized to DC arm, 29 pts were randomized to continue chemo. In pts with rapid disease progression baseline serum S100b level was significantly higher compared to patients with objective response or stable disease (0.874±1.15 mcg/L vs. 0.361±0.66 mcg/L, P=0.002). Similar results were found for baseline serum LDH level (559.8±469.7 U/L vs. 412.5±184.4 U/L, P=0.005) and serum S100b level after 2 cycles of chemo (0.688±0.855 mcg/L vs. 0.187±0,29 mcg/L, P<0.001). Contrary, baseline CD3+HLA-DR+ and CD4+CD25+ lymphocytes levels after 2 cycles of chemo were significantly higher in pts with disease control (11.9±8.9% vs. 8.9±5.3%, P=0.047 and 14.4±8.3% vs. 11.3±5.5%, P=0.036 respectively).In pts randomized to DC arm following markers were associated with long lasting objective response or stable disease course (>6 months): lower baseline S100b level (0.133±0.120 mcg/L vs. 0.445±0.406 mcg/L, P=0.014), lower S100b level after 2 cycles of chemo (0.105±0.095 mcg/L vs. 0.255±0.154 mcg/L, P=0.048), higher proportion of active CD8+lymphocytes prior to vaccination (74.7±3.6% vs. 51.7±14.2%, P=0.05); and more prominent increase of NK-cells CD3-CD16+CD56+ from baseline (increase in 76.5%±41.12% vs. 4.5±28.8%, P=0.01). Conclusions: Biochemical and immunological markers may be helpful when selecting patients with metastatic melanoma for immunotherapy with dendritic cell vaccine.

Muscle Damage Markers

The objective of this study was to investigate the effect of running versus cycling exercises upon serum S100B levels and typical markers of skeletal muscle damage such as creatine kinase (CK), aspartate aminotransferase (AST) and myoglobin (Mb). Although recent work demonstrates that S100B is highly expressed and exerts functional properties in skeletal muscle, there is no previous study that tries to establish a relationship between muscle damage and serum S100B levels after exercise. We conducted a cross-sectional study on 13 male triathletes. They completed 2 submaximal exercise protocols at anaerobic threshold intensity. Running was performed on a treadmill with no inclination (RUN) and cycling (CYC) using a cycle-simulator. Three blood samples were taken before (PRE), immediately after (POST) and 1 h after exercise for CK, AST, Mb and S100B assessments. We found a significant increase in serum S100B levels and muscle damage markers in RUN POST compared with RUN PRE. Comparing groups, POST S100B, CK, AST and Mb serum levels were higher in RUN than CYC. Only in RUN, the area under the curve (AUC) of serum S100B is positively correlated with AUC of CK and Mb. Therefore, immediately after an intense exercise such as running, but not cycling, serum levels of S100B protein increase in parallel with levels of CK, AST and Mb. Additionally, the positive correlation between S100B and CK and Mb points to S100B as an acute biomarker of muscle damage after running exercise.
