Özet

Amaç: Sirotik ve nonsirotik portal hipertansiyon tanısı konulan hastalarda trombopoetin ve dalak hacminin trombositopenideki etkisini araştırmaktır. Yöntem: Çalışmaya portal hipertansiyonu olan 74 hasta (grup 1: 28 nonsirotik; grup 2: 46 sirotik) alındı. Dalak hacmi magnetik rezonans görüntüleme ile hesaplandı. Trombopoetin ve hyaluronik asid serumda ELISA ile tayin edildi. Bulgular: Dalak hacmi grup 1’de (1375±658.74 mL) grup 2’ye (981.78±512.39 mL) göre anlamlı olarak büyüktü. Grup 1’de trombopoetin düzeyi 76.6±30.39 pg/ml, hyaluronik asid düzeyi 78.17±66.67 ng/ml olarak bulundu. Trombopoetin (99.89±38.5 pg/ml) ve hyaluronik asid (271.97±197.34 ng/ml) düzeyleri grup 2’de grup 1’den daha yüksekti (p<0.05). Her iki grupta da trombosit ve trombopoetin düzeyleri ile dalak hacmi arasında negatif korelasyon saptandı (p <0.05). Sirotik ve nonsirotik gruplarda serum trombopoetin düzeyleri ile trombosit düzeyleri arasında korelasyon yoktu. Fakat tüm grupta trombopoetin düzeyi ile dalak hacmi arasında negatif korelasyon saptandı (p=0.044, r= - 0.23). Dalak hacmi nonsirotik hastalarda anlamlı olarak daha büyük olmasına rağmen, trombosit düzeyleri her iki grupta da benzerdi. Sonuç: Bu çalışma portal hipertansif hastalarda trombositopeninin esas nedeninin dalaktaki sekestrasyon olduğunu göstermiştir. Bu sonuçlar trombosit düzeyleri üzerinde trombopoetin sentezindeki azalmadan daha çok trombopoetin üretimi ve yıkımı arasındaki dengenin önemli olabileceğini düşündürmüştür.

Abstract

Background/aims: To determine the role of thrombopoietin and spleen volume in thrombocytopenia diagnosed in cirrhotic and noncirrhotic portal hypertensive patients. Methods: Seventy- four portal hypertensive patients (group 1: 28 noncirrhotic; group 2: 46 cirrhotic) were enrolled into this study. Spleen volume was measured by magnetic resonance imaging. Thrombopoietin and hyaluronic acid were detected by ELISA in sera. Results: Splenic volume was significantly higher in group 1 (1375±658.74 ml) than group 2 (981.78±512.39 ml). In group 1, thrombopoietin and hyaluronic acid levels were 76.6±30.39 pg/ml and 78.17±66.67 ng/ml, respectively. These values were significantly higher in group 2, at 99.89±38.5 pg/ml and 271.97±197.34 ng/ml, respectively (p<0.05). Platelet counts and thrombopoietin levels had a negative correlation with spleen volume in both groups (p<0.05). Serum thrombopoietin levels were not correlated with platelet counts in cirrhotic and noncirrhotic groups; however, thrombopoietin levels were negatively correlated with splenic volume in the whole group (p= 0.044, r= - 0.23). Although spleen volume was significantly larger in noncirrhotic patients, platelet counts were similar in both groups. Conclusions: This study confirms that splenic sequestration is the main factor in the thrombocytopenia in portal hypertensive patients. The balance of thrombopoietin production and degradation may be more important for platelet counts than decreasing synthesis.
