Abstract

We aimed to determine the etiology and changes of platelet parameters of elevated platelet counts. A prospective study was performed to evaluate all patients,who had at least one platelet count more than 450 x 109 L. 146 patients with thrombocytosiswere studied. Out of146 patients,16 (10.9%) had primary and 130 (89.1%) had secondary thrombocytosis. Among 16 patients with primary thrombocytosis: 6 (37.5%) patients with essential thrombocythaemia, 5 (31.25%) patients with chronic myeloid leukemia, 4 (25%) patients with polycythemia vera and 1 (6.25%) patient with myelofibrosis and myeloid metaplasia. The most frequent causes of secondary thrombocytosis were infection (50.7%), burn (20%), malignancy (11.5%), bleeding (6.9%) and chronic inflammation (6.1%) . Primary thrombocytosis was significantly associated with a higher platelet count, mean platelet volume (MPV) and platelet distribution width (PDW). Compared with secondry thrombocytosis, primary thrombocytosis was significantly associated with platelet counts of more than 1000 x 109/L (1.5% compared to 50%) When a patient has an unexplained high platelet count, the combined interpretation platelet count, MPV and PDW appears to be highly useful in the differential diagnosis of thrombocytosis. Most cases of thrombocytosis are reactive and only a small percentage of patients has primary thrombocytosis.

Özet

Bu çalışmamızda trombositozda trombosit parametre değişiklikleri ve etiyolojisinin belirlenmesi amaçlanmıştır. Trombosit sayısı 450.000 üzerinde olan tüm hastalar prospektif olarak değerlendirilmiştir. Toplam 146 hasta değerlendirmeye alındı. Onaltı hastada primer trombositoz belirlendi; 6 (%37.5) vakada esansiyel trombocytemia, 5 (%31.3) vakada KML (kronik myelositer lösemi), 4 (%25) hastada polisitemia vera, bir (% 6.3) hastada myelofibrozis ve myeloid metaplazi. Sekonder trombositozun en sık nedenleri, enfeksiyon (%50.7), yanık (%20), malignansi (%11.5), kanama (%6.9) ve kronik inflamasyon (%6.1) idi. Primer trombositozda anlamlı olarak trombosit sayıları daha yüksekti, ayrıca ortalama trombosit hacmi (MPV) ve trombosit dağılım genişliği (PDW) daha fazlaydı. Sekonder trombositozla kıyaslandığında primer trombositozda trombosit sayıları 1000x 109/L’nin üzerinde olanların sayısı anlamlı olarak daha yüksekti (%1.5 vs %50). Yüksek trombosit sayısı tesbit edildiği durumlarda, trombosit sayısıyla birlikte, MPV ve PDW dikkate alınarak trombositoz ayırıcı tanısı araştırılmalıdır. Trombositozların büyük kısmı reaktiftir, oldukça küçük bir kısmı primerdir.
