Can lymphocyte to monocyte ratio be used as a predictor of atherosclerotic carotid plaques in elderly adults?
Abstract
Introduction: The lymphocyte/
monocyte ratio(LMR), a novel marker of inflammation, has been accepted as a
predictor for atherosclerosis. However, the relationship between LMR and
carotid atherosclerotic stenosis in older healthy adults remains undefined.
Aim: The aim of our study was to determine
retrospectively the association of LMR with carotid stenosis, evaluated by
carotid artery doppler ultrasonography.
Materials and Methods: Our study included 102 patients, aged ≥ 65 years,hospitalized in our clinic from January 2011 to December 2017. Blood samples were taken from all of the patients to determine the levels of white blood cell subtypes. LMR was calculated as the ratio of lymphocyte count to monocyte count. Patients also underwent carotid artery doppler ultrasonography to define the presence of carotid stenosis.
Results:After dividing the patient group
into two subgroups according to carotid stenosis, the patients with severe
stenosis(carotid stenosis> 50% )(n=42) had lower
lymphocyte count and LMR value but higher monocyte count. Then the patient
group with carotid stenosis> 50% were divided into two subgroups again. While
a statistically significant difference was found between the LMR values of
these 3 groups, this difference was in favor of the first group(carotis
stenosis ˂50%). The optimum cut-off LMR values was determined as 2.49
with a sensitivity of 72.6% and a specificity of 80.7%.
Conclusion: Lower levels of LMR can be used as a strong predictor of the presence
of severe carotid stenosis in elderly adults.

Lenfosit/monosit oranı yaşlı erişkinlerde aterosklerotik karotis plaklarınının bir göstergesi olarak kullanılabilir mi?
Abstract
Amaç: Bu
çalışmadaki amacımız geriye dönük olarak LMO’nun karotis arter doppler
ultrasonografi ile saptanmış karotis stenozu ile ilişkisini saptamaktır.
Yöntem: Çalışmamız 65 yaş ve üzerinde, Ocak 2011- Aralık 2017 tarihleri arasında kliniğimizde takip edilen 102 hastayı içermektedir. Tüm hastalardan beyaz küre alt tiplerinin ölçümü için kan örneği alındı. LMO değeri lenfosit sayısının monosit sayısına oranı olarak hesaplandı. Hastalara ayrıca karotis stenozunu saptamak için karotis arter doppler ultrasonografisi de uygulandı.
Bulgular:
Hasta grubu karotis stenozu ciddiyetine göre iki alt gruba
ayrıldıktan sonra, ciddi darlığı olan hastaların(karotis stenozu> %50)(n=42)
daha düşük lenfosit sayısı ve LMO değerine ancak daha yüksek monosit sayısına
sahip olduğu saptandı. Daha sonra karotis stenozu %50’nin üzerinde olan
hastalar tekrar iki alt gruba ayrıldı. Her üç grup arasında LMO değeri
açısından istatistiksel olarak anlamlı fark saptanırken; bu fark birinci grup
lehineydi.(karotis stenozu ˂%50). LMO değeri için en iyi kesim noktası %72.6 duyarlılık ve %80.7
seçicilikle 2.49 olarak saptandı.
Sonuç: Düşük
LMO seviyeleri yaşlı erişkinlerde ciddi karotis stenozunun varlığı için güçlü
bir gösterge olarak kullanılabilir.
