dc.description.abstractKronik hemodiyaliz (HD) hastalarında hipertansiyon (HT) yaygın birproblemdir. Bu çalışmanın amacı kronik HD hastalarında nondipper kan basıncınınnedenlerini incelemek ve bu nedenlerin kardiyovasküler hastalık risk faktörlerini nasıletkilendiğini araştırmaktırÇalışmaya antihipertansif ilaç kullanmayan normotansif 57 kronik HD hastası ile19 sağlıklı kişi alındı. Tüm olgulara ambulatuar kan basıncı monitorizasyonu yapıldı.Ekokardiyografi ile sol ventrikül kitle indeksi (SVKİ), karotid arter intima-mediakalınlığı (CCA IMT) ve damar kompliansı ölçümleri yapıldı. Bioimpedans analizi ilevücut sıvılarının ölçümleri yapıldı. Hastaların kan örnekleri HD seanslarınınbaşlangıcında alındı.Hastalarda sistolik kan basıncı (SKB)'ndaki düşmeyle ilişkili parametrelerinPearson korelasyon testi ile incelenmesi sonucunda yaş, SVKİ, ekstrasellüler sıvı/vücutağırlığı (kg) ( ECF/kg), ECF/kg², high sensitif CRP (hsCRP), CCA İMT ile negatif ilişkigösterdiği saptandı ( sırasıyla r:-0.23, r:-0.39, r:-0.38, r:-0.39, p<0.05), Stepwise lineerregresyon analizi ile incelenen SKB'ındaki nondipping durumun nedenlerinin ECF/kg,hsCRP ve CCA İMT olduğu saptandı ( korelasyon katsayısı sırasıyla: -0.332, -0.243, -0.251, p<0.05)Kronik HD hastalarının kardiyovasküler mortalitesini ve morbiditesiniazaltmada sıkı volüm kontrolü sonucu hipertansiyonun kontrol edilmesinin yanı sıra,noktürnal kan basıncı yönünden dipper olmalarının da gerektiğini gözledik. Kronik HDhastalarında sıkı volüm kontrolü ile inflamasyon önlenebilir ve kardiyovaskülerolaylardan korunulabilir. Fakat bu hipotezi kanıtlamak için daha fazla çalışmagerekmektedir.
dc.description.abstractHypertension (HT) is a common problem in hemodialisis (HD). The aim ofthis study is to investigate the causes for nondipper HT in chronical HD patients and toexplore their impact on risk factors for cardio-vascular diseases.57 chronical HD patients with an average age of 50 ± 18 and 19 healthyindividuals with an average age of 47 ± 13 were included in the study. Blood pressureparameters were measured by applying Ambulatory Blood Pressure Monitorization(ABPM) on the arm without fistula for the period between two HD sessions. LeftVentricle Mass Index (LVMI) Carotid Intima-Media Thickness (IMT), and veincompliance was measured by echocardiogramm. Bioimpedance analysis was appliedbefore and immediately after the HD. Routine heamatological and biochemical analysiswere performed in all cases, and high sensitive C - reactive protein (hsCRP), vonWillebrand Factor (vWF), and homosisteine levels were measured.Statistically, the average Sistolic Blood Pressure (SBP) and Diastolic BloodPressure (DBP) was found significantly higher in patients compared to the controlgroup, however sistolic decrease rates were found lower (p<0.001). The averageextracellular fluid/kg (ECL/kg) rate, LVMI, arteria carotis IMT, and hsCRP levels weresignificantly higher in the patient group (p<0.05). When classified according tonondipper and dipper patients, both groups showed similar average total SBP and DBP,ans similar average day SBP and DBP (p>0.05). average night SBP and DBP was foundsignificantly higher in the nondipper group (p<0.05). ECL/kg and ECL/kg2 rates,LVMI, arteria carotis IMT, and hsCRP levels were significantly higher in the nondipperpatient group, however the hemoglobin levels were lower (p<0.05). A negative relationwas determined between the sistolic decrease rate and LVMI, ECL/kg, ECL/kg2,hsCRP and arteria carotis IMT (r:-0.23, r:-0.39, r:-0.41, r:-0.38, r:-0.32, r:-0.39, p<0.05,respectively). Using Stepwise linear regretion analysis it was shown that ECL/kg,hsCRP and arteria carotis IMT were the factors influencing the sistolic decrease.We showed that increase in ECL/kg, LVMI, and arteria carotis IMT, andhsCRP may be the causes for nondipper HT. We determined that a salt-poor diet andstrict volume control is necessary to control HT in chronical HD patients. However,keeping patients normotensive with strict volume control does not necessarily mean adecrease in cardiovascular mortality and morbidity, but it is required that the patientsare dipper in nocturnal blood pressure, too.en_US
