Yenidoğan yoğun bakım birimindeki erken doğmuş bir bebekte geç başlangıçlı Streptococcus pasteurianus sepsisi

Otuzuncu gebelik haftasında ve 1 300 g ağırlığında erken doğ- muş erkek bebekte doğum sonrası 37. günde, apne, siyanoz, letarji ve kapiler dolum zamanında uzama bulguları gelişti. Akut faz be- lirteçleri ve immatür/toplam nötrofil oranı yüksek bulundu. Sep- sis tanısı alan hasta, körlemesine başlanan meropenem ile başarılı bir şekilde tedavi edildi. Kan kültüründe Streptococcus pasteurianus üredi. S. pasteurianus D grubu streptokoklar içinde yer alan Strep- tococcus bovisin alt grubundandır ve önceki adı S. bovis tip II/2dir. Literatürde bu bakteriye bağlı çok az sayıda yenidoğan enfeksiyon olgusu bulunmaktadır. Bilgimize göre bu, Türkiyeden bildirilmiş S. pasteurianusun neden olduğu ilk yenidoğan sepsis olgusudur. Bu olgu ile literatür gözden geçirilerek S. pasteurianus ile oluşan yeni- doğan enfeksiyonların klinik özellikleri belirlenmeye çalışılmıştır. (Türk Ped Arş 2014; 49: 157-9)

Late-onset Streptococcus pasteurianus sepsis in a preterm baby in a neonatal intensive care unit

Apnea, cyanosis, lethargy and prolongation in capillary filling time de- veloped on the postnatal 37th day in a preterm baby who was born at the 30th gestational week with a birth weight of 1 300 g. Acute phase reactants and immature/total neutrophil count ratio were found to be high. The patient who was diagnosed with sepsis was successfully treated with meropenem which was started empirically. In his blood culture Streptococcus pasteurianus grew. S. pasteurianus is in the subgroup of streptococcus bovis which is one of the D group streptococci and its previous name is S. bovis type II/2. In the literature, there are very few cases of neonatal infection related with this bacterium. As far as we know, this is first case of neonatal sepsis caused by S. pasteurianus in Turkey. In addition, we tried to determine the clinical properties of neo- natal infections arising from S. pasteurianus by reviewing the literature. (Türk Ped Arş 2014; 49: 157-9)
