The relationship between lymphocyte / monocyte ratio and short-term mortality in acute ischemic stroke patients.
Abstract
Objective:The
lymphocyte / monocyte ratio (LMR) obtained by dividing the number of
lymphocytes by monocyte number is considered a new marker of
inflammation.Recent studies have found an inverse relationship between LMR
levels and 3-month functional recovery after acute ischemic stroke (AIS).Our
aim in this study is to determine the role of LMR in the short-term mortality
of AIS patients.
Method:Our study is a single centered
retrospective study. 508 patients with AIS, who presented to our clinic between
January 2011 and December 2017 and 512 healthy control with similar age and sex
were included to our study.
Results: While
monocyte count was higher in the patient group.lymphocyte count and LMR levels
were higher in the control group. The patient group was then divided into two
subgroups according to 30-day mortality. When the patients in the first group
survivied (n = 396), the patients in the second group diedwithin 30 days after
AIS(n = 112).In the second group, the lymphocyte count and LMR levels were lower
when the monocyte count was elevated (p < 0.001).Logistic regression
analysis showed that uric acid, CRP and LMR are independent variables for the
occurrence of 30-day mortality. In addition, ROC analysis revealed that an LMR value below 2.95 can be used as
a marker for the short-term mortality of AIS(AUC:0.77, %95 CI:0.67-
0.86,sensitivity:%72.6,specificity:%80.7).
Conclusion: Based on
our results, it can be concluded that lower LMO levels in patients with AIS are
related to short-term mortality.

Abstract
Amaç: Lenfosit
sayısının monosit sayısına bölünmesi ile elde edilen lenfosit/ monosit
oranı(LMO) inflamasyonu göstermede yeni bir belirteç olarak kabul edilmektedir.
Son çalışmalar, LMO düzeyleri ile akut iskemik inme (Aİİ) sonrası 3 aylık fonksiyonel
iyileşme arasında ters bir ilişki olduğunu saptamıştır. Bu çalışmadaki amacımız
LMO’nun Aİİ hastalarının kısa dönem mortalitesini göstermedeki rolünü
saptamaktır.
Yöntem: Çalışmamız tek merkezli retrospektif bir çalışmadır. Ocak 2011- Aralık 2017 yılları arasında kliniğimizde Aİİ tanısı ile izlenmiş 508 hasta ile benzer yaş ve cinsiyete sahip 512 kontrol çalışmamıza dahil edildi.
Bulgular:
Monosit sayısı hasta grubunda yüksekken lenfosit sayısı ve LMO
düzeyleri kontrol grubunda yüksek saptandı. Hasta grubu daha sonra 30 günlük
mortaliteye göre iki alt gruba ayrıldı. İlk grupta hayatta kalan hastalar
varken(n=396) ikinci gruptaki hastalar Aİİ sonrası 30 gün içinde exitus
olmuştu(n=112). Bu iki grup kıyaslandığında; ikinci grupta lenfosit sayısı ve
LMO düzeyleri düşükken, monosit sayısı yüksekti ( p < 0.001). Aİİ sonrası 30
günlük mortalite ile ilişkili risk faktörlerini belirlemek için yapılan
lojistik regresyon analizi ürik asit, CRP ve LMO’nun mortalite gelişimi için
bağımsız değişkenler olduğunu ortaya koydu. Ayrıca işlem karakteristiği eğrisi analizi ile LMO
için 2.95’in altındaki değerlerin Aİİ'ye bağlı 30 günlük mortaliteyi saptamada
kullanılabileceği gösterildi (EAA:0.77, %95
GA:0.67- 0.86,duyarlılık:%72.6,seçicilik:%80.7).
Sonuç: Sonuçlarımıza
dayanarak Aİİ’li hastalardaki düşük LMO düzeylerinin kısa dönem mortalite ile
ilişkili olduğu söylenebilir.
