Abstract

Amaç: Sevelamer, pleotropik etkisi ile prebiyotik olarak etki gösterebilir. Bu çalışmanın amacı sevelamerin ürik asit, HbA1c, lipid profili ve arteryel sertlik progresyonu üzerine etkisinin gösterilmesidir. Gereç ve Yöntem: Hemodiyalize giren ve aynı fosfor bağlayıcıyı (FB) 3 yıl kullanan 151 hasta çalışmaya dahil edildi. Hastalar kullandıkları FB’ye göre sevelamer bazlı FB (grup 1) ve kalsiyum bazlı FB (grup 2) olarak 2 gruba ayrıldı. Üç yıllık takipte biyokimyasal parametreler kayıt edildi. Arteryel sertlik başlangıçta ve 3. yılın sonunda aortik nabız dalga hızı (PWv) ölçümü ile belirlendi. Bulgular: Üç yıllık takipte ortalama ürik asid düzeyleri grup 1’de azalmışken grup 2’de stabil kaldı. Grup 1’deki hastaların %22,4’ünde ortalama ürik asid düzeylerinde 2 mg/dL’den fazla azalma saptandı. Diyabetik hastalarda HbA1c düzeyleri grup 1’de grup 2’ye göre daha düşüktü. PWv düzeyleri çalışmanın başında her 2 grup için de benzerdi. Ancak 3. yılın sonunda PWv düzeyleri grup 1’de grup 2’ye göre daha düşük saptandı. Sonuç: Sevelamer pleiotropik etki ile ürik asit düzeyini, düşük yoğunluklu lipoprotein-kolesterolü, HbA1c düzeyini azaltarak, fazla kalsiyum alımını engelleyerek kardiyovasküler riski azaltmaktadır. Hemodiyalize giren hastalarda sevelamer, kalsiyum bazlı fosfor bağlayıcılara göre arteryel sertlik progresyonunu da azaltarak kardiyovasküler risk profilini düzeltir.
