Bakteriell vaginos

Senast reviderad:
Sakkunnig:
Definition:
Illaluktande flytningar från vagina på grund av förändrad bakterieflora.
Förekomst:
Prevalensen i Europa är 5–25 %. Vanligaste orsaken till onormala flytningar hos fertila kvinnor.
Symtom:
Symtomen är sällan särskilt uttalade och tillståndet är asymtomatiskt hos 50 %. Det dominerande besväret är en tunn flytning som luktar.
Kliniska fynd:
Gråvita, homogena, tunnflytande, i vissa fall skummande, flytningar. Obehaglig lukt. Som regel ingen uppenbar vulvit eller vaginit.
Diagnostik:
Vaginalt pH >4,5. Clue cells kan ses vid mikroskopi. Flytningarna reagerar med 10 % KOH och utsöndrar aminer och fettsyror med fisklukt.
Behandling:
Lokal antibiotika i första hand.
