Abstract
Amaç: Bu çalışmada ağır tıkayıcı uyku apne sendromlu (OSAS) hastalarda kan koagülabilitesiyle ilişkili
Ortalama Trombosit Hacmini (MPV) ve Plateletcriti (PCT) değerlendirmeyi amaçladık.
Gereç ve yöntemler: Uyku ünitesinde Eylül 2013 öncesi polisomnografi yapılan 98 hastanın kayıtları
retrospektif değerlendirildi. Tüm olgular apne-hipopne indeksine(AHİ) göre AHİ <5 / saat (s=48) AGrubu
(kontrol), AHİ ≥ 30 / saat ile B Grubu (s = 50) şeklinde gruplandırıldı. MPVve PCT(plateletcrit) otomatik bir
kan hücresi sayacı kullanılarak ölçüldü. Polisomnografik bulgularla, demografik ve kan parametreleri
karşılaştırıldı.
Bulgular: A ve B grupları arasında MPV (7.17±0.98 karşılık 7.54±1.21fL, p=0.66) ve PCT (0.218±0.06
karşılık 0.212±0.05, p=0.66) açısından anlamlı farklılık bulunamadı. Ağır OSAS grubunda MPV, PCT ile
AHİ parametreleri arasında anlamlı korelasyon saptanmadı(r=0.37, p=0.801 ve r=0.61, p=0.624).
Sonuç: MPV ve PCT değerlerinde ağır OSAS'lı hastalarda kontrole göre anlamlı yükseklik bulunmadı.Bu
bulgular yapılan ilk çalışmaların aksine MPV'nin OSAS'ın ağırlığıyla ilişkili bir parametre olmadığı ve
OSAS'ın doğrudan trombosit aktivitesini etkilemediğini düşündürmektedir.

Abstract
Objective: In this study we aimed to evaluate the mean platelet volume (MPV) and Plateletcrit (PCT)
associated with blood coagulability in patients with severe obstructive sleep apnea syndrome (OSAS).
Materials And Methods: The polysomnography recordings of 98 patients admitted to the sleep laboratory
before September 2013 were retrospectively evaluated. All cases were grouped according to their AHI value
as AHI <5 / h (n = 48) Group A (control) and AHI ≥ 30 / hour and Group B (n = 50). MPV and PCT
(plateletcrit) was measured using an automatic blood cell counter. Polysomnographic findings, demographic
data and blood parameters were compared. Results: No significant differences were found between Aand B groups with respect to PCT (0.218±0.06 vs.
0.212±0.05, p=0.66) and MPV (7.17±0.98 vs. 7.54±1.21fL, p=0.66). In severe OSAS group, MPV and PCT
werenot correlated with AHİ (r=0.37, p=0.801 and r=0.61, p=0.624).
Conclusion: MPV and PCT levels werenot higher in severe OSAS group compared to the control group.
Unlike previous studies, these findings suggest that MPV isnot associated with the severity of OSAS and
OSAS does not directly affect the platelet activity
