Abstract

Objective: Several biomarkers have been used in the evaluation of the diagnosis,prognosis, and response to antibiotherapy. In this study we evaluated biomarkers frequently used in the diagnosis and prognosis of bacterial infections among geriatric patients in palliative care.Methods: In this descriptive, cross-sectional study iinpatients treated in the palliative care unit of our hospital for a period of more than two days between November 2015 and February 2016 were included.Results: A total of 63 palliative care patients with a median age of 80 years were included; 55.6% of the patients were male. Eighty-one percent of the patients developed an infection , so they were treated with an antibiotic. Biomarkers measured on the first day of hospitalization were evaluated in two groups as patients with and without infections. ROC analysis revealed the diagnostic powers of C-reactive protein (CRP) and albumin were 76.2% and 73.9%, respectively (p<0.05). The diagnostic power of the CRP/albumin ratio was 81.3% (p<0.001). In ROC analysis CRP had a predictive power of 83.9% and albumin of 78.0% (p<0.05) predict prognosis in patients with infection, infections, evaluate prognosis and assess treatment response. With a cut-off value of 8.23 mg/dl, CRP showed 75.8% specificity and 88.9% sensitivity in detecting infection; but for albumin, the corresponding values were 44.4% and 93.9% with a cut-off value of 2.27 mg/dl, respectively. The CRP/albumin ratio had a prognostic predictive power of 84.3% (p<0.001) with 72.4% specificity and 94.4% sensitivity in detecting infection at a cut-off value of 2.89.Conclusion: We think that combined evaluation of CRP and albumin which are indicators of inflammation and nutritional status within 24 hours of hospitalization is important in determining prognosis.

Özet

Amaç: Enfeksiyon tanısı, prognozu ve antibiyotik yanıtının değerlendirilmesinde birçok biyobelirteç kullanılmaktadır. Çalışmamızda, palyatif bakım alan geriatrik hastalardaki bakteriyel enfeksiyon tanı ve prognozunda sık kullanılan biyobelirteçlerin değerlendirilmesi amaçlanmıştır.Yöntemler: Bu çalışmaya Kasım 2015 ve Şubat 2016 tarihleri arasında hastanemiz Palyatif Bakım Ünitesinde iki günden uzun süre yatan bütün hastalar dahil edilmiştir. Araştırma tanımlayıcı-kesitsel tipte bir araştırmadır. Bulgular: Yaş ortalaması 80 yıl olan toplam 63 palyatif bakım hastası çalışmaya alınmıştır. Hastaların %55,6'sı erkektir. Hastaların %81'inde enfeksiyon gelişmiş ve bu nedenle antibiyotik tedavisi kullanılmıştır. Hastane yatışının birinci gününde değerlendirilen biyobelirteçler, enfeksiyon gelişen ve gelişmeyen hasta gruplarında ayrı olarak değerlendirilmiştir. Yapılan ROC analizinde, CRP'nin tanı gücü %76,2, albüminin tanı gücü %73,9 olarak tespit edildi (p<0,05). CRP'nin albumine oranın enfeksiyon tanısındaki gücü %81,3 olarak tespit edildi (p<0,001).CRP ve albüminin enfeksiyon gelişen hastalarda prognoz tahmini için yapılan ROC analizinde, CRP'nin tanı gücü %83,9; albuminin tanı gücü %78,0 olarak tespit edildi (p<0,05). Enfeksiyon tanısında CRP'nin belirlenen 8,23 mg/dl kesme değeri ile özgüllüğü %75,8, duyarlılığı %88,9, albuminin belirlenen 2,27 mg/dl kesme değeri ile özgüllüğü %44,4, duyarlılığı %93,9 olarak tespit edilmiştir. CRP'nin albümine oranının prognoz tahmin gücü %84,3 olarak tespit edildi (p<0,001). Enfeksiyon tanısında CRP/albumin belirlenen 2,89 kesme değeri ile özgüllüğü %72,4 duyarlılığı %94,4 olarak tespit edilmiştir.Sonuç: İnflamasyon ve beslenme göstergeleri olan CRP ve albuminin hastane yatışının ilk 24 saatinde birlikte değerlendirilmesinin prognozu belirleme açısından önemli olduğunu düşünmekteyiz.
