Herpes Labialis Reaktivasyonunda IgM Pozitifliği

Hayır, herpes labialis reaktivasyonunda (tekrarlayan dudak uçuğunda) IgM genellikle pozitifleşmez; IgM antikor yanıtı primer (ilk kez) HSV-1 enfeksiyonunu gösterir, reaktivasyon durumlarında ise IgG antikorları yüksek titrede bulunur.

Serolojik Yanıt Paternleri

Primer Enfeksiyon vs Reaktivasyon

  • Primer HSV-1 enfeksiyonunda (örneğin herpetik gingivostomatit), IgM antikorları enfeksiyonun erken döneminde ortaya çıkar ve akut enfeksiyonu gösterir 1, 2.

  • Reaktivasyon durumlarında (tekrarlayan herpes labialis), virus trigeminal gangliyonda latent halde kalır ve periyodik olarak reaktive olur, ancak bu reaktivasyonlar yeni bir IgM yanıtı oluşturmaz 1.

  • Tekrarlayan herpes labialis olan hastalarda yapılan çalışmalarda, IgG antikorları yüksek titrelerde bulunurken (ortalama 1:14,050), IgM yanıtı gözlenmemiştir 3.

Klinik Önemi

Tanısal Değerlendirme

  • Herpes labialis tanısı klinik olarak konur ve serolojik testler rutin olarak gerekmez 4, 5.

  • IgG antikorları geçmiş enfeksiyonu ve immüniteyi gösterir; tekrarlayan herpes labialis öyküsü olan hastalarda IgG pozitifliği beklenir 3.

  • Vezikül sıvısında yüksek titrelerde lökosit interferonu (IFN-alpha) bulunur, bu da lokal immün yanıtı gösterir 6.

Önemli Klinik Ayrımlar

  • Çocuklarda primer HSV-1 enfeksiyonu herpetik gingivostomatit olarak ortaya çıkar ve bu durumda IgM pozitif olabilir 1, 2.

  • Erişkinlerde tekrarlayan herpes labialis reaktivasyonu temsil eder ve IgM pozitifliği beklemek yanlıştır 7, 3.

  • Herpes labialis olan erişkinlerde HSV menenjiti riski artmamıştır; HSV-2 menenjite neden olan predominant virüstür, HSV-1 değil 7.

Klinik Yönetim İçin Çıkarımlar

  • Tekrarlayan herpes labialis tanısı için serolojik test gereksizdir; klinik görünüm yeterlidir 4, 5.

  • Tedavi prodromal fazda veya lezyon başlangıcından sonraki 24 saat içinde başlatılmalıdır, çünkü pik viral titreler ilk 24 saatte oluşur 8, 1.

  • Yılda 6 veya daha fazla atak yaşayan hastalarda süpresif tedavi düşünülmelidir (valasiklovir 500 mg günde bir kez) 8.
