Objective: Platelet functions have important roles in the development of vascular complications in diabetic patients. Platelets with increased volume have increased activity compared to smaller ones; therefore, mean platelet volume (MPV) is used as a marker for platelet activity. In the present study, we evaluated MPV in patients with type II diabetes mellitus (DM) and its associations with diabetic microvascular and macrovascular complications. Methods: Consecutive type II diabetic patients were screened from outpatient clinic of Internal Medicine Department of Diskapı Yıldırım Beyazıt Education and Researsch Hospital, Ankara, Turkey. A total of 48 patients with type II DM and 30 age and gender matched healthy subjects constituted the study population. For all subjects a complete blood count including MPV, fasting blood glucose level and lipid parameters were studied. In diabetic patients, duration of diabetes and HbA1C level, presence of microvascular and macrovascular complications were noted additively. Mean platelet volume was compared between diabetic patients and healthy counterparents. Then, among diabetic patients, MPV was compared between the ones with and without microvascular and macrovascular complications. Results: Mean platelet volume was found significantly higher in diabetic patients compared to non-diabetic healthy subjects. Diabetic patients with at least one of the microvascular complications had significantly higher MPV than those without microvascular damage.Higher MPV levels have also been shown in diabetics with macrovascular complications compared to the ones without macrovascular disease. Conclusion: Mean platelet volume was found to be higher in type II diabetics and those having any of microvascular or macrovascular diabetic complications.

Amaç: Diyabetik hastalarda vasküler komplikasyonların gelişiminde trombositler önemli rol oynamaktadır. Büyük trombositler küçüklere oranla daha aktif olup, ortalama trombosit hacmi (MPV) trombosit aktivitesini göstermede kullanılan bir belirteçdir. Biz bu çalışmamızda MPV\'nin tip 2 diyabetes mellituslu hastalarda ve diyabetin mikrovasküler ve makrovasküler komplikasyonlardaki ilişkisi araştırmayı amaçladık. Yöntemler: Çalışmaya Dışkapı Eğitim ve Araştırma Hastanesi Dahiliye polikliniğinde takipli olan 48 tip 2 diyabetli ve 30 sağlıklı hasta dahil edilmiştir. Tüm hastalarda tam kan sayımı, açlık kan şekeri ve lipid parametreleri çalışıldı. Diyabetik hastalarda diyabet süresi, HbA1c düzeyi, mikrovasküler ve makrovasküler komplikasyon varlığı araştırıldı. Ortalama trombosit hacmi diyabetik ve sağlıklı kontrol grubu arasında ve diyabetik kolda komplikasyon olan olmayan grup arasında karşılaştırıldı. Bulgular: Diyabetik hastalarda MPV, non-diyabetik sağlıklılarla karşılaştırıldığında anlamlı yüksek saptandı. En az bir mikrovasküler komplikasyonu olan hastalarda olmayanlara göre MPV belirgin yüksek saptandı. Makrovasküler komplikasyonu olan hastalarda MPV olmayan hastalara göre yüksek bulundu. Sonuç: Hem diyabetiklerde hem de mikro-makrovasküler komplikasyonları olan diyabetik hastalarda MPV yüksek bulunmuştur.
