Abstract

Objective: Human herpes viruses have an important role in the pathogenesis of the central nervous system (CNS) infections seperating two general category as aseptic meningitis and encephalitis. In this study we aimed to investigate the frequency of Herpes Simplex Virus (HSV- 1/2) in cerebrospinal fluid (CSF), biochemical specifications and also bacteriological culture of CSF samples in suspected cases of viral infections of CNS in our region. Material-Method: In this study, 110 CSF samples sent to our laboratory from patients with suspected CNS infection between January 2016- December 2017 were evaluated retrospectively. HSV-1/2 DNA presence was evaluated qualitatively with Real-time PCR technique by using Artus® HSV ½ QS-RGQ (Qiagen, Hamburg, Germany) kits on Rotor-Gene system (Qiagen, Hamburg, Germany). Also, protein and glucose levels in CSF samples were recorded. Furthermore bacteriological culture of CSF samples were evaluated simultaneously. Results: While, HSV-1 DNA was detected by nucleic acid testing in 5 of the 110 patients (4.5%), HSV-2 DNA was not detected. The CSF glucose and protein levels were found normal in 42 (38%) and 27 (25%) patients, respectively. The CSF glucose levels of the patients, who were found to be positive for HSV-1 were high in four patients. Also CSF protein levels in HSV-1 positive group were detected high in 3 patients. HSV ½ negative 8 different samples were detected positive in bacteriological culture. Conclusions: Because of the high mortality and morbidity rates in CNS infections, initiating of specific antiviral treatment after the rapid identification of the agent is crucial. Even though encephalitis caused by herpes viruses were seen more frequent, other viral and bacterial agents must be kept in mind. Therefore necessity of moleculer methods are taking over like multiplex PCR which detects multiplexed viral and bacterial agents at the same time and in a short time.

Özet

Amaç: Aseptik menenjit ve ensefalit olarak iki genel kategorideincelenen santral sinir sistemi (SSS) enfeksiyonlarınınetiyolojisinde insan herpes virüslerinin önemli rolü vardır.Bu çalışmada, bölgemizde viral SSS enfeksiyonlarıdüşünülen olgulardan gönderilen beyin omurilik sıvısı (BOS)örneklerinde Herpes Simplex virüsü (HSV-1/2) sıklığı veincelenen BOS örneklerinin biyokimyasal özelliklerini ve aynızamanda bakteriyolojik kültür üremelerinin de irdelenmesiamaçlanmıştır.Materyal-Metot: Ocak 2016-Aralık 2017 tarihleri arasındalaboratuvarımıza gönderilen 110 adet BOS örneği çalışmakapsamında retrospektif olarak değerlendirildi. Artus® HSV½ QS-RGQ kiti ve Rotor-Gene Q 5Plex HRM (Qiagen,Hamburg, Almanya) real-time PZR sistemi kullanılarakBOS örnekleri HSV yönünden kalitatif olarak incelendi.BOS örneklerinde protein ve glukoz ölçüm değerleri dekaydedilmiştir. Ayrıca gönderilen BOS örneklerinin eşzamanlı olarak bakteriyolojik kültürleri de yapıldı.Bulgular: Laboratuvarımıza gönderilen örneklerin 5’inde(%4,5) HSV-1 pozitif saptanırken, hiçbir örnekte HSV-2 tespit edilmedi. BOS’un biyokimyasal parametrelerideğerlendirildiğinde; örneklerin 42’sinde (%38) BOS glukozdüzeyleri, 27’sinde ise (%25) ise BOS protein değerlerinormal düzeylerde saptandı. HSV-1 pozitif hastaların BOSglukoz düzeyi dördünde yüksek, protein düzeyi ise üç hastadayüksek bulundu. HSV ½ negatif olduğu tespit edilen 8 farklıörnekte kültürde üreme saptandı.Sonuç: SSS enfeksiyonlarında mortalite ve morbidite oranıyüksek olduğundan etkenin çok hızlı tanımlanması sonrasındaspesifik antiviral tedaviye başlanılması hayati öneme sahiptir.Herpes virüslerinin neden olduğu ensefalit vakaları iledaha sık karşılaşılsa da diğer viral ve bakteriyel etkenler deakılda tutulmalıdır. Bu nedenle bir örnekte çok sayıda viralve bakteriyel ajanın aynı anda ve kısa sürede saptanabildiğimultipleks PZR paneli gibi moleküler testlerin gerekliliği önplana çıkmaktadır.
