Abstract

Objective: We aimed to detect and compare group B streptococcus (GBS) colonization in pregnant women at thirdtrimester using real-time polymerase chain reaction (real-time PCR) and culture methods. Methods: Vaginal swab specimens were taken for screening of GBS from 100 women between 35-37 weeks ofgestation who were attending to antenatal outpatient unit of Obstetrics and Gynecology Department of CerrahpasaMedical Faculty from May 2014 to September 2014.Results: Rates of GBS colonization was %5 and %7 by culture and real-time PCR methods, respectively. Using cul ture as the gold standard; sensitivity and specificity for real-time PCR were 100% and 97.9%, respectively. Anysignificant difference was not detected between GBS colonization with age groups, education levels, number ofprevious pregnancies, smoking habits, history of antibiotic use, and contraceptive method.Conclusion: Real-time PCR technique has proven to be as sensitive as the culture method. Also, real-time PCR mayprovide a rapid diagnostic tool for GBS detection potentially allowing a more effective intrapartum antibioticprophylaxis and lower infant morbidity and mortality. However, the inability to use PCR test in every laboratory andits high cost creates a handicap.

Özet

maç: Üçüncü trimesterdeki gebelerde grup B streptokok (GBS) kolonizasyonunu gerçek zamanlı polimeraz zincirreaksiyonu (real-time PCR) ve kültür yöntemleri kullanarak tespit etmeyi ve bu yöntemleri karşılaştırmayıamaçladık. Yöntem: Mayıs 2014-Eylül 2014 tarihleri arasında Cerrahpaşa Tıp Fakültesi Kadın Doğum Anabilim Dalı Polikliniğine35-37. gebelik haftaları arasında başvuran 100 kadından GBS taraması için vajinal swab örnekleri alındı. Bulgular: GBS kolonizasyon oranları; kültür ve real-time PCR yöntemleriyle sırasıyla % 5 ve % 7 idi. Kültür altınstandart kabul edildiğinde gerçek zamanlı PCR için duyarlılık ve özgüllük sırasıyla % 100 ve % 97,9 idi. GBS koloni zasyonu ile yaş grupları, eğitim düzeyleri, önceki gebelik sayıları, sigara içme alışkanlıkları, antibiyotik kullanımöyküsü ve kontraseptif yöntemleri arasında anlamlı bir fark yoktu. Sonuç: Gerçek zamanlı PCR tekniğinin kültür yöntemi kadar duyarlı olduğu kanıtlanmıştır. Ayrıca, gerçek zamanlıPCR, GBS tespitinde hızlı bir tanı yöntemi olarak daha etkili bir intrapartum antibiyotik profilaksisi sağlar. Bu sayedeinfantlarda morbidite ve mortalitenin düşük olmasına yardımcı olur. Fakat, PCR testinin her laboratuardakullanılamaması ve yüksek maliyeti handikap oluşturmaktadır.
