Abstract

Background

Aneurysmal subarachnoid hemorrhage (aSAH) leads to a robust systemic inflammatory response. We hypothesized that an early systemic glycolytic shift occurs after aSAH, resulting in a unique metabolic signature and affecting systemic inflammation.

Methods

Control patients and patients with aSAH were analyzed. Samples from patients with aSAH were collected within 24 h of aneurysmal rupture. Mass spectrometry–based metabolomics was performed to assess relative abundance of 16 metabolites involved in the tricarboxylic acid cycle, glycolysis, and pentose phosphate pathway. Principal component analysis was used to segregate control patients from patients with aSAH. Dendrograms were developed to depict correlations between metabolites and cytokines. Analytic models predicting functional outcomes were developed, and receiver operating curves were compared.

Results

A total of 122 patients with aSAH and 38 control patients were included. Patients with aSAH had higher levels of glycolytic metabolites (3-phosphoglycerate/2-phosphoglycerate, lactate) but lower levels of oxidative metabolites (succinate, malate, fumarate, and oxalate). Patients with higher clinical severity (Hunt-Hess Scale score ≥ 4) had higher levels of glyceraldehyde 3-phosphate and citrate but lower levels of α-ketoglutarate and glutamine. Principal component analysis readily segregated control patients from patients with aSAH. Correlation analysis revealed distinct clusters in control patients that were not observed in patients with aSAH. Higher levels of fumarate were associated with good functional outcomes at discharge (odds ratio [OR] 1.76, 95% confidence interval [CI] 1.15–2.82) in multivariable models, whereas higher levels of citrate were associated with poor functional outcomes at discharge (OR 0.36, 95% CI 0.16–0.73) and at 3 months (OR 0.35, 95% CI 0.14–0.81). No associations were found with delayed cerebral ischemia. Levels of α-ketoglutarate and glutamine correlated with lower levels of interleukin-8, whereas fumarate was associated with lower levels of tumor necrosis factor alpha.

Conclusions

Aneurysmal subarachnoid hemorrhage results in a unique pattern of plasma metabolites, indicating a shift toward glycolysis. Higher levels of fumarate and lower levels of citrate were associated with better functional outcomes. These metabolites may represent targets to improve metabolism after aSAH.

Empfohlen wird jetzt auch eine Musiktherapie sowie bei unklarem diagnostischem Befund ein Tau-PET, und Depressive mit leichten kognitiven Störungen sollten eine Verhaltenstherapie erhalten – das sind einige wichtige Änderungen der aktuellen S3-Leitlinie Demenzen.

Frauen akkumulieren Tau-Protein schneller als Männer

Frauen mit einer hohen Beta-Amyloid-Last im Gehirn aggregieren mehr Tau-Protein als Männer mit vergleichbaren Amyloidwerten. Ähnliches gilt für Frauen mit einem ApoE4-Allel. Dafür sprechen die Daten einer Metaanalyse von Menschen im präklinischen Alzheimerstadium.

Frauen mit Apoplex in Deutschland nicht benachteiligt – oder doch?

Eine Analyse von Daten des statistischen Bundesamtes spricht dafür, dass Frauen in der Schlaganfallbehandlung nicht benachteiligt sind. Im Detail bleiben aber Fragen offen.

MS-Medikamente absetzen: ab 60 Jahren eine Option

Wann können ältere MS-Kranke ihre krankheitsmodifizierende Therapie gefahrlos absetzen? Bisher lieferten kontrollierte Studien hier keine eindeutigen Antworten. Eine neue Auswertung der Studie DISCOMS deutet auf einen grenzwertigen Nutzen ab 60 Jahren.
