Evaluation of systemic endothelial functions by flow mediated vasodilatation method in polycythemia (Polisitemide sistemik endotelyal fonksiyonların akış aracılı genişletme yöntemi ile değerlendirilmesi)

Year 2016, Volume: 1 Issue: 1, 1 - 8, 15.08.2016

Abstract

Aim: Polycythemia is a disease state in which the proportion of blood volume
that is occupied by red blood cells increases.  Flow-mediated
vasodilation (FMD) is a non-invasive ultrasound method of evaluating
endothelial function.
The
aim of this prospective study was to compare the systemic endothelial functions
by FMD method in patients with polycythemia with
control group.

Method: The
present study included 50 patients with polycytemia (hemoglobin (Hb) ≥16.5 g/dl) and 61 healthy control group aged
≥ 18 years at Kayseri
Education and Research Hospital
 were included. In all
individuals, the following laboratory evaluations were performed: complete
blood count (CBC), serum iron indices, 
and routine biochemical tests. Also, all participants underwent the FMD
study at Cardiology department with Doppler ultrasound.

Results: The results of 111 participants
were analyzed. On the other hand, the rate of
smoking was 76% in the polycythemia group, while it was 36.1% in the control
group (p< 0.005). Likewise, Hb, hematocrit and
serum lipid parameters were significantly increased in polycythemia group
except
high density lipoprotein (HDL) cholesterol (p < 0.001). Also, FMD was significantly
reduced in
polycythemia
group compared with control group (7.78 ± 4.83% vs. 10.98 ± 7.86%,
respectively) (p= 0.010).







Conclusion: The
results of the study indicate that polycythemia is associated with endothelial
dysfunction and hyperlipidemia.
As the noninvasive ultrasound method for
peripheral endothelial testing is generally accurate and reproducible, and can
be performed serially, FMD can be used safely in patients with polycythemia to
evaluation of endothelial functions.

Amaç: 
Polisitemi, kan volümünün bir parçasını teşkil eden eritrosit
miktarındaki artışla karakaterize bir patolojik durumdur. Akış aracılı genişletme (FMD) yöntemi, sistemik
vasküler fonksiyonların değerlendirilmesinde giderek önemi artan bir
non-invaziv tetkik olup, çeşitli hastalıklarda bu yöntem ile vasküler endotel
hakkında önemli bilgiler edinilmiştir.
Bu prospektif çalışmada amacımız,
polisitemik bireylerde FMD yöntemi ile vasküler fonksiyonları değerlendirmek ve
sağlıklı kontrol grubu ile karşılaştırmaktı.  

Metod: Bu çalışmaya; Kayseri Eğitim ve
Araştırma Hastanesi’ne başvuran 18 yaş ve üzeri, 61 sağlıklı ve Hb değeri
normal sınırlarda olan gönüllü ile, 50 polisitemi olgusu alındı. Polisitemi
tanısı için Hb > 16.5 g/dL baz alındı. 
Bireylerin tam kan sayımları, demir parametreleri ve rutin biyokimyasal
tetkikleri istendi. Katılımcılara Kardiyoloji kliniğinde Doppler ultrasonografi
eşliğinde FMD işlemi uygulandı.

Bulgular: Toplam 111 olgunun
değerlendirildiği çalışmada, gruplar arasında yaş, cinsiyet, vücut kitle
indeksi, hipertansiyon ve diabet oranları bakımından fark yoktu. Buna karşın,
sigara içim oranı polisitemi grubunda kontrol grubuna göre anlamlı şekilde
yüksekti (%76 ve %36.1, sırasıyla) (p< 0.005). Hb, hematokrit ve serum lipid
parametreleri de yüksek densiteli lipoprotein (HDL) kolesterol dışında
polisitemi grubunda anlamlı şekilde yüksekti (p < 0.001). Ayrıca, FMD oranı
polisitemik grupta kontrol grubuna göre anlamlı şekilde düşük bulundu (% 7.78 ±
4.83 ve %10.98 ± 7.86, sırasıyla)(p= 0.010).

 Sonuçlar: Bulgularımızla, polisitemik bireylerde vasküler
endotelyal fonksiyonların olumsuz etkilendiği ve hiperlipidemi birlikteliği
ortaya konmuştur. Non invaziv ve kolay uygulanabilen FMD yöntemi ile,
polisiteminin muhtemel endotelyal disfonksiyon gelişimindeki rolü
öngörülebilir.
