Analysis of C-reactive protein in pyelonephritis
Üriner kanal enfeksiyonu özellikle piyelonefrit farklı üropatojenlerin neden olduğu yaygın bir durumdur. C-reaktif protein (CRP) gibi vücut yanıt parametreleri önemli inflamatuar belirteç ve diagnostik testidirler. Bu çalışmanın amacı, üriner kanal enfeksiyonunu tanımlamak için farklı bakterilerin neden olduğu üriner kanal enfeksiyonu piyelonefritte CRP'nin faydasını saptamaktı. Al-Kindi Eğitim Hastanesi'ne (Bağdat, Irak) başvuran piyelonefrit klinik semptomlu 50 hasta, Ekim 2009'dan Kasım 2009'a kadar araştırıldı. Hastaların idrarları temiz bir şekilde toplandı. Üriner kanal enfeksiyonu için mikrobiyal ajanların izolasyonu için idrar örneklerinin kültürü yapıldı. İzole edilen bakteriler biyokimyasal testler kullanılarak tanımlandı. İnflamatuar yanıta ilişkili olarak CRP ölçüldü. En yaygın izole edilen bakteriler, Escherichia coli(%40), Enterobacter (%20) ve Klebsiella (%12) idi. En az sıklıkta görülen bakteriler,Staphylococcus aureus (%4), Staphylococcus pyogenes (%4) ve Staphylococcus fecalis (%4) idi. Sistemik inflamatuar yanıt (CRP) ile üriner kanal inflamatuar yanıt (piyüri) arasında anlamlı fark (P
Piyelonefritte C-reaktif protein analizi
Urinary tract infection especially pyelonephritis is a common condition worldwide caused by different uropathogens. The hostresponse parameters like C-reactive protein (CRP) are important inflammatory markers and diagnostic tests. The aim of this study was to assess the usefulness of CRP in urinary tract infection- pyelonephritis caused by different bacteria for defining the urinary tract infection (UTI). A total of fifty patients with clinical symptoms of pyelonephritis referred to Al-Kindi Teaching Hospital (Baghdad, Iraq), were investigated from October 2009 to November 2009. Clean-catch midstream urine of the patients was collected. Urine specimens were cultured for isolation of the microbial agents of UTI. The isolated bacteria were identified using biochemical tests. CRP were assessed in relation to the inflammatory responses. The most common isolated bacteria were Escherichia coli (40%), Enterobacter (20%) and Klebsiella (12%). The least frequent bacteria were Staphylococcus aureus (4%), Staphylococcus pyogenes (4%)and Staphylococcus fecalis (4%). There was a significant difference (P
