Abstract

Hintergrund/Zielsetzung:
Myalgische Enzephalomyelitis/Chronisches Fatigue-Syndrom (ME/CFS) ist eine komplexe neuroimmunologische Erkrankung mit begrenzten Therapieoptionen. Trotz der weit verbreiteten Nutzung von Nahrungsergänzungsmitteln (Dietary Supplements, DS) durch ME/CFS-Betroffene zur Linderung von Fatigue und begleitenden Symptomen ist die Evidenzlage bislang uneinheitlich. Ziel dieser systematischen Übersichtsarbeit ist es, eine aktualisierte Synthese zur Wirksamkeit von DS-Interventionen zu liefern und mögliche Wirkmechanismen zu diskutieren.

Methoden:
Die systematische Übersichtsarbeit wurde gemäß den PRISMA-Leitlinien durchgeführt. Eine systematische Literaturrecherche erfolgte in mehreren Datenbanken (Ebsco Host, PubMed, Scopus, Google Scholar) auf Basis der Suchbegriffe ME/CFS und Dietary Supplements mit Fokus auf Publikationen aus dem Zeitraum 1994 bis 2024. Primärer Outcome war Fatigue; sekundäre Outcomes umfassten psychisches Wohlbefinden, körperliche Aktivität und biochemische Marker. Zwei unabhängige Forschende führten ein mehrstufiges Screening der Studien durch und bewerteten Qualität und Verzerrungsrisiken mithilfe der Cochrane-Risikobewertungsinstrumente (RoB-2, ROBINS-I).

Ergebnisse:
Insgesamt wurden 14 Studien (N = 809) mit heterogenen Studiendesigns eingeschlossen, die überwiegend ein hohes Verzerrungsrisiko aufwiesen, vor allem aufgrund fehlender Daten und Selektionsbias. Einige Intervention

Despite the widespread use of Dietary Supplements (DSs) among ME/CFS patients to alleviate fatigue and associated symptoms, evidence remains inconclusive.

Methods: This systematic review was conducted according to PRISMA guidelines. Several databases (Ebsco Host, PubMed, Scopus, Google Scholar) were used for the systematic search, which was based on the broad search terms ME/CFS and DS with a focus on publications between 1994 and 2024. The primary outcome was fatigue, with additional considerations including psychological well-being, physical activity, and biochemical markers. Two independent researchers screened the studies for eligibility in a multi-stage process and assessed quality and bias using Cochrane{\textquoteright}s risk of bias tools (RoB-2, ROBINS-I). Results: Fourteen studies (N = 809) of heterogeneous designs were included, showing a high risk of bias, mostly due to missing data and selection bias. While some interventions (L-carnitine and guanidinoacetic acid, oxaloacetate, CoQ10–selenium combination, NADH and NADH-CoQ10 combination) showed significant reductions in fatigue, methodological limitations, like small sample sizes and missing data, prevent firm conclusions. Mixed results were reported for secondary outcomes like cognitive function and inflammatory markers. Six studies noted adverse effects, including nausea and insomnia. Conclusions: Though some DSs showed potential in reducing fatigue in ME/CFS, methodological limitations and inconsistent results hinder definitive conclusions. Future research should improve diagnostic criteria and include more diverse populations.",
