Abstract

Background Advanced glycation and oxidation end products (AGEs) cause oxidative stress and trigger cytokine driven inflammatory reactions in vitro. The net effects on markers of inflammation and acute phase proteins in vivo as well as their influence on survival in hemodialysis patients are unknown.Methods We conducted a cross-sectional study in 312 stable hemodialysis patients and analyzed the interrelationships of AGEs and C-reactive protein (CRP) and their predictive effect on all-cause as well as cardiovascular mortality. Mortality was monitored prospectively over a period of 32 months. AGEs were determined by measuring total serum fluorescent AGEs (AGE-fl) and Nepsilon-(carboxymethyl)-lysine (CML).Results The levels of AGE-fl, CML and CRP were 3.2-, 3.8- and 10-fold higher as compared to healthy controls. AGE-fl and CML levels correlated significantly with each other but not with CRP or serum albumin. Patients with high (above median values) AGE-fl or CML levels (109 x 103 AU and 1.4 microg/mL, respectively) had a significant better survival than those with low (below median values) AGE-fl or CML levels. Patients with high CRP levels (above 7.7 mg/L = median value) had a better survival than those with low CRP (below median value) when AGE-fl or CML levels were high in parallel.Conclusions In contrast to in vitro data and to current hypotheses, the presence of high serum AGEs, as measured by AGE-fl and CML, were not linked to increased mortality. Statistically, high serum AGEs partly overcame the negative impact of the acute phase response on mortality in hemodialysis patients. Whether the benefit of high serum AGEs is an epiphenomenon or reflects a better nutritional support needs further studies.

  • The duration of the exercise event explains more than 50% of the variation in plasma IL-6 concentration.

    “During heavy exercise, such as a marathon, there is up to a 60-fold increase in plasma IL-6 concentration (209) , with the duration of the event explaining more than 50 % of the variation in concentration (210) .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
