POLİSİTEMİ

Polisitemi eritrositozis , eritrosit sayısı, hematokrit değer ve hemoglobin konsantrasyonunda artışla karekterize olan patolojik bir durumdur Polisitemi, absolut ve relatif polisitemi olarak; absolut polisitemi de primer polisitemia rubra vera ve sekunder uygun, uygunsuz olarak ikiye ayrılmaktadır. Eritropoietin seviyesi polisitemilerin ayırıcı teşhislerinde klinik olarak çok önemlidir. Eritropoietin seviyesi P. vera'da düşük, sekunder eritrositoziste yüksektir. Sekunder polisitemili hastalarda çoğunlukla idrar veya plazma ya da her ikisinde de Eritropoietin konsantrasyonu artmıştır. Bu derlemede, polisitemilerin sınıflandırılması, teşhis yöntemleri ve tedavi olanakları hakkında bilgiler verilerek, karşılaşılan şüpheli vakaların detaylı incelenmesinde yardımcı olabilecek bilgileri aktarmak amaçlanmıştır

POLYCYTHEMİA

Polycythemia erythrocytsis is a State characterizid by an elevated erythrocyte mass, hematocrit value and hemoglobin concentration. Polycythemia may be relative or absolute. Absolute polycythemia can be primary polycythemia rubra vera or secondary appropriate or inappropriate . Erythropoietin level is very important for differential diagnosis of polycythemia. Erythropoietin level is decreased in polycythemia vera and elevated in seconder erythrocytosis. Erythropoietin concentration is elevated in urine or plasma or either in patient with seconder polycythemia. In this review, it has been given some information about the classifıcation, diagnosis and treatment of polycythemia. It is aimed to give some Information that could heplful in detailed examination of suspected cases
