Abstract

Objective: In
this study, we aimed to investigate the prognostic value of neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios in patients
presenting with chronic obstructive pulmonary disease exacerbation.

Material and Methods: This was
a retrospective case control study. We searched the patients who admitted to
the emergency department with chronic obstructive
pulmonary disease exacerbation between 1^st January 2016 and 31th
December 2016. The patients who were discharged from emergency department or
hospitalized in wards were classified as good clinical outcome group (group 1).
The patients who were intubated and admitted to intensive care unit or the ones
who died were classified as poor clinical outcome group (group 2). We evaluated
whether there was a statistically significant difference between the two groups
according to the neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios and
whether these parameters effected 30 days mortality.

Results: One
thousand and sixty patients were included in the study. The hemoglobin levels,
leukocyte, neutrophil, platelet and lymphocyte counts of all patients were respectively 12,9 g/dL (11,50-14,20), 10,9
103/µL (8,42-14,60), 7,87 103/µL (5,60-11,18), 252 103/µL (197,25-311), 1,75
103/µL (1,15-2,47). Medians of neutrophil-to-lymphocyte
and platelet-to-lymphocyte ratios of all patients were 4,54 (2,64-8,15)
ve 142,08 (98,20-221,03). There were no statistically significant difference
between the groups according to the neutrophil-to-lymphocyte
and platelet-to-lymphocyte ratios (respectively p=0,1, p=0,4). There
also was not a significant relationship between the neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios and 30 days
mortality.

Conclusion: There
was no significant relationship between the neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios and poor
prognosis in patients presenting with chronic obstructive pulmonary disease
exacerbation. We believe that these parameters are not eligible markers for
predicting the prognosis in these patients.

ACİL SERVİSE KRONİK OBSTRÜKTİK AKCİĞER HASTALIĞI AKUT ALEVLENMESİ İLE BAŞVURAN HASTALARDA NÖTROFİL-LENFOSİT VE PLATELET-LENFOSİT ORANLARININ HASTA PROGNOZUNA ETKİSİ

Abstract

Amaç: Bu
çalışmanın amacı acil servise Kronik Obstrüktik Akciğer Hastalığı (KOAH)
alevlenme ile başvuran hastaların prognozunu öngörmede Nötrofil-lenfosit oranı
(NLO) ve Platelet-lenfosit oranının (PLO) etkinliğinin araştırılmasıdır.

Gereç ve Yöntem: Çalışma retrospektif vaka kontrol
çalışması olarak tasarlanmıştır. 1 Ocak 2016 ile 31 Aralık 2016 tarihleri
arasında acil servise KOAH alevlenme ile başvuran tüm hastalar tarandı. Acil
servisten taburcu olan veya servis yatışı yapılan hastalar iyi klinik sonlanım
grubu olarak sınıflandırıldı (Grup 1). Entübe olan, yoğun bakım ihtiyacı olan
ya da eksitus olan hastalarsa kötü klinik sonlanım grubu (Grup 2) olarak kabul
edildi. Grup 1 ve 2 arasında NLO ve PLO açısından anlamlı fark olup olmadığına
bakıldı. Ayrıca bu parametrelerin tek başlarına 30 günlük mortaliteye olan
etkileri de araştırıldı.

Bulgular: Çalışmaya
toplam 1060 hasta dahil edildi. Tüm hastaların laboratuvar değerlerine bakıldığında
hemoglobin, lökosit, nötrofil, platelet ve lenfosit ortanca değerleri sırasıyla
12.9 g/dL (11.50-14.20), 10.9 x 10³/µL (8.42-14.60), 7.87 x 10³/µL
(5.60-11.18), 252 x 10³/µL (197.25-311), 1.75 x 10³/µL
(1.15-2.47). Yine tüm hastalardaki ortanca NLO ve PLO ortanca değerleri de
sırasıyla 4.54 (2.64-8.15) ve 142.08 (98,20-221.03) olarak hesaplanmıştır.
Hastalar iyi ve kötü kritik sonlanımlarına göre gruplandırıldıklarında kötü
prognoz ile hem NLO hem de PLO arasında istatistiksel anlamlı ilişki
bulunmamıştır (sırasıyla p=0.1; 0.4). Hastaların 30 günlük mortalite
durumlarına bakıldığında da kötü prognoz ile hem NLO hem de PLO arasında
istatistiksel anlamlı ilişki bulunmamıştır (sırasıyla p=0.7; 0.6).

Sonuç: Acil
servise KOAH alevlenme ile başvuran hastalarda NLO ve PLO düzeyleri ile kötü
prognoz arasında anlamlı ilişki tespit edilememiş olup bu parametreler prognoz
belirteçleri olarak kullanmaya uygun değildir.
