Epstein-Barr virus Einar Þór Bogason

Virology Herpesvírus Hýsill er maður Enveloped, double stranded DNA virus hefur einkennandi Viral Capsid Antigen (VCA) Hýsill er maður sýkir aðallega B-fr. um C3 complement receptor. Dvalartími er 2-7 vikur

Faraldsfræði Ein algengasta sýking í heimi Smitast með munnvatni 90-95% fullorðna hafa antibody gegn EBV Smitast með munnvatni blóðsmit er mjög sjaldgæft einstaklingur getur smitað allt að 18 mán eftir smit. (15-25 % smitandi í mörg ár). Ekki þekkt tilvik um reactiveringu

Einkenni Oftast einkennalaust í ungum börnun eldri börn og fullorðnir fá oftar einkirningasótt (mononucleosis)

Einkirningasótt Hiti (39°-40°C) Hálsbólga Slen tonsillopharyngitis þykkt tonsillar exudat petechiur í góm lymphadenopathy eymslalausir ant og post cervical eitlar alg.

Einkirningasótt Splenomegaly og hepatomegaly í 30-50 % tilvika 90-100% fá útbrot ef amoxicillin er gefið Innan við 5% hafa langvarandi þreytu og hita (chronic mono)

Fylgikvillar Útbrot sprungið milta loftvegaþrengsli meningoencephalitis (mjög sjaldgæft) langvinn þreyta

Greining Hematology Serology TWC 12-18 þúsund 60-70% lymphocytar og >10% atypical Ekki specifískt Serology Monospot (næmni:85% sértækni:97% í >4ára) heterophil antibody EBV specific antibody prof notar IgM VCA antibody

Mismunagreiningar CMV Streptococcal pharyngitis HIV (acute) toxoplasmosis Hepatitis Krabbamein

Meðferð Oftast engin Glucocorticoids (Acyclovir) hvíld, hitalækkandi o.s.frv. Glucocorticoids ef um efri loftvega obstruction er að ræða (Acyclovir)

Prognosa Nánast alltaf “self limiting” á 6-8 vikum um 1% fær neurologísk vandamál cranial nerve palsies og encephalitis “Alice in Wonderland” syndrome metamorphopsia tengsl við Burkitt lymphoma og nasopharyngeal carcinoma
