Abstract

Objective: The morbidity and mortality associated with the community-acquired and nosocomial respiratory tract infections (RTIs) pose a significant and growing challenge to clinical practitioners. The aim of this retrospective study was to determine the etiologic agents in patients with RTIs in Başkent University Adana Hospital and to evaluate their antimicrobial resistances. Methods: Sputum and trans tracheal aspirate (TTA) cultures from April 2016 to May 2018 were evaluated. Conventional methods and an automatized microbiological system were used for the identification and the antimicrobial susceptibility tests were performed according to the CLSI 2016 standards. Results: A total of 641 bacterial pathogens were isolated from 245 sputum and 396 TTA cultures of 442 patients. Most prevalent isolates were, Acinetobacter baumannii (25%), Pseudomonas aeruginosa (12.6%), Klebsiella spp. (14.7%), Escherichia coli (10%), Haemophilus influenzae (6.9%), Staphylococcus aureus (5.5%) and Streptococcus pneumoniae (5.1%). More than one agent was isolated from 116 patients (26.2%). Overall 80.6% of A. baumannii, 86.5% of P. aeruginosa and 79.5% of Klebsiella pneumoniae isolates were recovered from the intensive care unit patients. Conclusion: In conclusion, the increase in resistance rates of respiratory tract infection isolates was found to be remarkable. The high resistance rates to all antibiotic groups of the predominant isolates A. baumannii and K. pneumoniae are worrying. It is necessary to perform studies showing the distribution and resistance pattern of such microorganisms isolated from patient with RTIs at certain time intervals for correct antibiotic use. The results are thought to be useful for updating empirical treatment protocols and guiding clinicians on the correct use of antibiotics.

Özet

Amaç: Toplum kökenli ve nozokomiyal solunum yolu enfeksiyonları (SYE) ile ilişkili morbidite vemortalite, klinisyenler için önemli ve artan bir sorun oluşturmaktadır. Bu retrospektif çalışmanınamacı, Başkent Üniversitesi Adana Hastanesi’ndeki SYE hastalarında etiyolojik ajanları belirlemekve antimikrobiyal direnç profillerini değerlendirmektir.Yöntem: Nisan 2016-Mayıs 2018 arasında balgam ve derin trakeal aspirat (DTA) kültürlerindenizole edilen bakteriyel etkenler çalışmaya dâhil edilmiştir. Bakterilerin tanımlanmasında konvansiyonel yöntemler ve otomatize bir sistem kullanılmış ve izolatların antibiyotik duyarlılıkları CLSI2016 standartlarına göre değerlendirilmiştir.Bulgular: Toplamda 442 hastadan alınan 245 balgam ve 396 DTA kültüründen patojen kabuledilen 641 bakteri izole edilmiştir. En sık izole edilen etkenler Acinetobacter baumannii (%25),Pseudomonas aeruginosa (%12.6), Klebsiella spp. (%14.7), Escherichia coli (%10), Haemophilusinfluenzae (%6.9), Staphylococcus aureus (%5.5) ve Streptococcus pneumoniae (%5.1)’dir.Hastaların 116’sında (%26.2) birden fazla farklı etken üremiştir. Toplamda, A. baumannii izoleedilen hastaların %80.6’sının, P. aeruginosa’nın %86.5 ve Klebsiella pneumoniae’nın %79.5’ininyoğun bakım ünitesinde yatan hastalar olduğu görülmüştür.Sonuç: Sonuç olarak, solunum yolu enfeksiyonu etkeni izolatların direnç oranlarındaki artış dikkatçekici bulunmuştur. En yaygın saptanan izolatlar olan A. baumannii ve K. pneumoniae’nın tüm antibiyotik gruplarına yüksek direnç oranları göstermesi endişe vericidir. Doğru antibiyotik kullanımı içinbelirli zaman aralıklarında SYE’li hastalardan izole edilen bu tür mikroorganizmaların dağılım vedirenç profillerini gösteren çalışmaların yapılması gereklidir. Sonuçların ampirik tedavi protokollerinin güncellenmesinde ve klinisyenlerin doğru antibiyotik kullanımı konusunda yönlendirilmesindeyararlı olacağı düşünülmektedir.
