Vancomycin-resistant enterococci : A structured literature review and analysis of the molecular epidemiology in the Nordic countries (English)
Abstract [sv]

Introduktion: Bärarskap eller sjukdom av vancomycinresistenta enterokocker (VRE) är anmälningspliktigt och smittspårningspliktig i Sverige. Smittspridning sker och för att kunna följa smittkedjor görs molekylärepidemiologisk typning av VRE-isolaten. 

Syfte: Att göra en deskriptiv analys över det molekylärepidemiologiska läget av vancomycinresistenta enterokocker i de nordiska länderna och hur läget har utvecklats de senaste 25 åren. 

Metod: Strukturerad litteraturstudie. Sökningar genomfördes i Medline Ebsco och Web of Science. Analysen skedde med narrativ syntes. 

Resultat: Flera olika sekvenstyper (ST) har funnits i Norden mellan år 2000–2025. I Danmark sågs initialt E. faecium vanA ST80 och ST117, men omkring 2015 blev ST203 den dominerande klonen, följt av ST1421 som runt 2019. Samtidigt ökade andelen vanB-bärande isolat, där ST80 och ST117 var de vanligaste sekvenstyperna. I Sverige och Norge har olika sekvenstyper förekommit, men inget tydligt spridningsmönster kan ses i denna studie. Slutsatser kring det molekylärepidemiologiska läget av VRE i Finland och på Island kan ej dras då ingen data från dessa länder var med i analysen.

Slutsats: I Danmark kan det ses att spridning av vissa framgångsrika sekvenstyper av VRE har funnits. I Sverige och Norge kan inte en tydlig spridning ses. För att minska sjukdomsbördan av VRE behövs ett robust övervakningssystem och goda möjligheter till epidemiologisk typning för att identifiera smittspridning och vidta preventiva åtgärder.

Abstract [en]

Introduction: Carriage or infection with vancomycin-resistant enterococci (VRE) is notifiable and requires contact tracing in Sweden Molecular epidemiological typing is used to follow transmission chains. 

Aim: To provide a descriptive analysis of the molecular epidemiology of VRE in the Nordic countries and how it has developed over the past 25 years. 

Methods: A structured literature review. Searches were performed in Medline Ebsco and Web of Science. The analysis was conducted using narrative synthesis. 

Results: Multiple sequence types (STs) have been present in the Nordic countries between 2000 and 2025. In Denmark, E. faecium vanA ST80 and ST117 were initially observed, but around 2015 ST203 emerged, followed by ST1421 which became the dominant clone around 2019. At the same time, the proportion of vanB-carrying isolates increased, with ST80 and ST117 being most prevalent. In Sweden and Norway, various sequence types have been identified, but no clear pattern of spread can be observed in this study. Conclusions regarding the molecular epidemiological situation of VRE in Finland and Iceland cannot be drawn, as no data from these countries were included in the analysis. No conclusions could be drawn for Finland or Iceland due to lack of data. 

Conclusion: VRE E. faecium is the most prevalent VRE type in the Nordic countries, with several circulating sequence types. In Denmark, the spread of certain successful clones can be observed. To reduce the burden of VRE, robust surveillance systems and access to molecular typing are essential to identify transmission and enable appropriate interventions.
