BACKGROUND: To investigate inflammatory processes during ovarian hyperstimulation, we have studied the soluble receptor for advanced glycation end products (sRAGE) levels in sera and follicular fluids of women undergoing in vitro fertilisation (IVF) cycle. METHODS: A total of thirty-three women undergoing IVF treatment were recruited, the number of follicles in investigated IVF cycles was 18 +/- 10 (mean +/- SD), oocytes 12 +/- 8, and the clinical pregnancy rate was 42% (14/33). The control group of serum samples was comprised of 35 healthy female blood donors. Sera and follicular fluids were examined for sRAGE levels by enzyme-linked immunosorbent assay (sRAGE ELISA, Quantikine, R&D Systems). RESULTS: Serum levels of sRAGE in women after ovarian hyperstimulation and induction of ovulation (1039 +/- 493 pg/mL) were significantly lower than in healthy blood donors (1535 +/- 438 pg/mL), p = 0.045. Follicular sRAGE levels (4355 +/- 1100 pg/mL) were significantly higher than serum levels (1039 +/- 493 pg/ml), p < 0.001. Serum sRAGE levels showed significant negative correlation with the number of stimulated follicles (r = -0.71, p = 0.01) and retrieved oocytes (r = -0.54, p = 0.048). Women who successfully conceived after the IVF showed significantly higher sRAGE levels in follicular fluid (4595 +/- 925 pg/mL) compared to women who did not conceive (3986 +/- 806 pg/mL), p = 0.031. CONCLUSIONS: Concentration of sRAGE in follicular fluid is several-fold higher compared to serum and most other biological fluids investigated until this time. It supports the hypothesis that mammalian ovulation can be compared to an inflammatory event. A significant negative correlation of serum sRAGE with the yield of follicles and oocytes, together with the high follicular sRAGE levels, in particular in women who conceive after the IVF, could be explained by the essential outflow of sRAGE to the follicular compartment.

PURPOSE: The soluble receptor for advanced glycation end-products (sRAGE) is a marker of lung epithelial injury and alveolar fluid clearance (AFC), with promising values for assessing prognosis and lung injury severity in acute respiratory distress syndrome (ARDS). Because AFC is impaired in most patients with ARDS and is associated with higher mortality, we hypothesized that baseline plasma sRAGE would predict mortality, independently of two key mediators of ventilator-induced lung injury. METHODS: We conducted a meta-analysis of individual data from 746 patients enrolled in eight prospective randomized and observational studies in which plasma sRAGE was measured in ARDS articles published through March 2016. The primary outcome was 90-day mortality. Using multivariate and mediation analyses, we tested the association between baseline plasma sRAGE and mortality, independently of driving pressure and tidal volume. RESULTS: Higher baseline plasma sRAGE [odds ratio (OR) for each one-log increment, 1.18; 95% confidence interval (CI) 1.01-1.38; P = 0.04], driving pressure (OR for each one-point increment, 1.04; 95% CI 1.02-1.07; P = 0.002), and tidal volume (OR for each one-log increment, 1.98; 95% CI 1.07-3.64; P = 0.03) were independently associated with higher 90-day mortality in multivariate analysis. Baseline plasma sRAGE mediated a small fraction of the effect of higher ΔP on mortality but not that of higher VT. CONCLUSIONS: Higher baseline plasma sRAGE was associated with higher 90-day mortality in patients with ARDS, independently of driving pressure and tidal volume, thus reinforcing the likely contribution of alveolar epithelial injury as an important prognostic factor in ARDS.

Receptor for advanced glycation end products (RAGE) may be involved in the pathogenesis of the cancer progression and metastasis. Pathological effects mediated via RAGE are physiologically inhibited by soluble RAGE (sRAGE), so the higher sRAGE levels may confer the patients with cancer with better outcome. The aim was to study sRAGE and RAGE gene polymorphisms in patients with breast cancer. The authors studied sRAGE and RAGE polymorphisms in 120 patients with breast cancer (subdivided based on the clinical stage, histologic grading, expression of hormonal and Her2/neu receptors) and in 92 healthy controls. Despite higher serum concentrations of AGEs, serum concentrations of sRAGE were lower in patients with breast cancer compared to healthy controls (1581 +/- 777 versus 1803 +/- 632 ng/mL, p < 0.05). Serum levels of sRAGE were higher in patients with advanced breast cancer (stage III), lower grade and positive estrogen receptors, and intermediate positivity of Her2/neu receptors and were also influenced genetically (Gly82Ser and 2184 AG polymorphisms of the RAGE gene). Decreased sRAGE levels in patients with breast cancer may contribute to the progression of the disease. Patients with better outcome (low grade and positive estrogen receptors) have higher sRAGE levels. Progression of the disease, may, however, increase sRAGE levels, possibly as a compensatory mechanism to counteract further progression.

OBJECTIVE: The receptor for advanced glycation end products, RAGE, plays an important role in the pathogenesis of several diseases. sRAGE, soluble receptor for advanced glycation end products, is an inhibitor of the pathological effect mediated via RAGE. The aim of this study was to assess the usefulness of measuring sRAGE concentration in pregnant women with threatening preterm labor. METHODS: Serum levels of sRAGE, interleukin-6 (IL-6) and routine markers of inflammation were determined in 46 pregnant women with threatening preterm labor, 35 healthy pregnant women and 15 non-pregnant controls. RESULTS: Serum levels of sRAGE in healthy pregnant women were significantly lower than in non-pregnant controls (669+/-296 vs. 1929+/-727 pg/mL, P<0.05). Women with threatening preterm birth had a significantly higher concentration of serum sRAGE in comparison with healthy pregnant women (819+/-329 pg/mL vs. 669+/-296 pg/mL, P<0.05). Conversely, patients with PPROM had significantly lower levels of sRAGE compared with patients with threatening premature labor (600+/-324 pg/mL, P<0.05). sRAGE correlated negatively with leukocyte counts (r=-0.325, P<0.05). CONCLUSIONS: sRAGE might be a new and promising marker of premature labor, especially with the symptoms of PPROM.

OBJECTIVES: The receptor for advanced glycation end-products (RAGE) takes part in the pathogenesis of many diseases, including diabetes mellitus and cancer. AGE-precursors are detoxified by glyoxalase (GLO). sRAGE, soluble RAGE, is an inhibitor of pathological effects mediated via RAGE. The aim was to study sRAGE and polymorphisms of RAGE (AGER) and GLO genes in patients with pancreas cancer (PC). DESIGN AND METHODS: The studied group consisted of 51 patients with PC (34 with impaired glucose tolerance-IGT, 17 without IGT), 34 type 2 DM and 154 controls. For genetic analysis, the number of patients was increased to 170. Serum sRAGE was measured by ELISA and all polymorphisms (RAGE -429T/C, -374T/A, 2184A/G, Gly82Ser and GLO A419C) were determined by PCR-RFLP and confirmed by sequencing. RESULTS: Soluble RAGE is decreased in patients with PC compared to patients with DM and controls (975+/-532 vs. 1416+/-868 vs. 1723+/-643pg/mL, p<0.001). Patients with PC and IGT have lower sRAGE levels compared to patients with PC without IGT (886+/-470 vs. 1153+/-616pg/mL, p<0.05). No relationship of sRAGE to the stage was found. We did not show any difference in allelic and genotype frequencies in all RAGE and GLO polymorphisms among the studied groups. CONCLUSION: This is the first study demonstrating decreased sRAGE in patients with pancreas cancer. Its levels are even lower than in diabetics and are lowest in patients with PC and IGT. Our study supports the role of glucose metabolism disorder in cancerogenesis. Further studies are clearly warranted, especially with respect to potential preventive and therapeutic implications.

AIM: The main objective was to examine the relationship between the soluble receptor for advanced glycation end products (sRAGE) and calprotectin concentrations in faeces and serum of patients with inflammatory bowel diseases (IBD) during biological treatment with infliximab. MATERIALS AND METHODS: A total of 29 IBD patients treated with infliximab were evaluated. Calprotectin and sRAGE in serum and faeces and serum IL-6 and CRP were measured during the induction regimen of infliximab treatment at weeks (W) 0, 2 and 10. RESULTS: At W0, a significant increase in faecal calprotectin was found in IBD compared to healthy persons (690 +/- 696 microg/g and 23 +/- 7 microg/g, respectively, p < 0.001). No clear difference was found in serum sRAGE levels in IBD cohort compared to healthy controls (772 +/- 274 pg/mL and 720 +/- 107 pg/mL, respectively, p = 0.159); however, a significant negative correlation was found between faecal calprotectin levels and serum concentrations of sRAGE in the active IBD cohort (r = -0.518, p = 0.004). In the stool eluates, sRAGE levels were non-measurable. In the group of responders-to-treatment, the initial surge in both faecal and serum calprotectin levels as well as CRP and IL-6 was followed by a significant decrease on W10. Surprisingly, no significant changeovers were seen in serum sRAGE concentrations in responders neither in W2 nor in W10. CONCLUSIONS: Unlike other examined local and systemic inflammatory markers, serum sRAGE did not change during the infliximab treatment, despite the initial correlation with the degree of mucosal inflammation.
