dc.description.abstractGiriş: Hemodiyaliz hastalarında, kognitif fonksiyonların, sağlıklı popülasyona göredaha kötü olduğu gösterilmiştir. N-terminal B Tipi natriüretik peptid öncüsü; NT-pro-BNP, ve Makrofaj İnhibitör Sitokin-1 (MIC-1/GDF-15) düzeylerinin non-renal hastapopülasyonunda kognitif fonksiyonlarla ilişkili olduğu bilinmektedir. Biz bu çalışmada,hemodiyaliz hastalarında volüm, kardiyak fonksiyonlar ve mortalite ile ilişkili olduğubilinen bu iki molekülün, kognitif fonksiyonlar ile olan ilişkisini literatürde ilk olarakinceledik.Hastalar-Metod: En az 3 aydır hemodiyaliz tedavisi alan 94 hasta çalışmaya alındı.Okur-yazar olmayan, 65 yaş üstü, kalp yetmezliği (EF<%40), serebrovasküler hastalık,demans, depresyon öyküsü olan hastalar çalışmaya alınmadı. Kognitif fonksiyonlarınölçümü için Standardize Mini Mental Test ve Montreal Bilişsel Değerlendirme testi(MoCA) uygulandı. Hastalardan eş zamanlı (haftanın ikinci seansı, diyaliz sonunda)alınan kan örneklerinde NT-proBNP ve MIC-1/GDF-15 düzeyleri ELISA metoduylaçalışıldı.Sonuçlar: Hastaların yaş ortalaması 48±2 olup, 58'i (%61.7) erkek ve % 21.3'üdiyabetikti. Ortalama diyaliz süresi 64±5 aydı. Hastaların standardize mini mental testtoplam skor ortalamaları 26.7±0.1, MoCA test toplam skor ortalamaları ise 20.1±0.4 idi.Hastaların %77.7 sinde kognitif fonksiyonların bozulduğu (MoCA total skor<24)görüldü. Serum NT-proBNP ortalamaları 7326±590 ng/l, ortalama MIC-1/GDF-15düzeyi ise 13.1±0.8 ng/ml idi. NT-ProBNP düzeyleri MIC-1/GDF-15, üre, sodyum veCRP ile pozitif, hemoglobin ve albumin ile negatif korele idi. Yine NT-proBNP düzeylerinin MoCA test gecikmeli hatırlama ve total skor ile, standardize mini mentaltestin ise kayıt hafıza skoru ile anlamlı negatif ilişkisi olduğu görüldü. Hastalar NTproBNPdüzeylerine göre 2 gruba ayrıldıklarında (10.500 üstü ve altı), MoCA test totalskorların anlamlı farklı olduğu görüldü.Sonuç: NT-proBNP düzeyleri hemodiyaliz hastalarında hipervoleminin birgöstergesidir. Diyaliz hastalarında mevcut olan hipervolemi kognitif fonksiyonlarınkötüleşmesine neden olabilir. Çalışmamızda literatürde ilk olarak NT-proBNPdüzeylerinin diyaliz hastalarında kognitif fonksiyonlarla olan ilişkisi gösterilmiştir ve bukonuda destekleyici çalışmalara ihtiyaç bulunmaktadır.Anahtar Kelimeler: Hemodiyaliz, kognitif fonksiyon, serum NT-proBNP, Makrofajİnhibitör Sitokin-1 (MIC-1/GDF-15)
dc.description.abstractIntroduction: It has been demonstrated that cognitive functions are worse inhemodialysis patients compared to the healthy population. It is known that NT-pro-BNP, and Macrophage Inhibitor Cytokine-1 (MIC-1/GDF-15) are associated withcognitive functions in the non-renal patient population. In the present study, weexamined the association of these two molecules, which are known to be associatedwith hypervolemia, cardiac dysfunction, and mortality in hemodialysis patients, withcognitive functions for the first time in the literature.Patients and Methods: A total of 94 patients who received hemodialysis for at least 3months were included in the present study. Patients who were illiterate, who were olderthan 65 years of age, who had severe heart failure (EF<40%), cerebrovascular disease,dementia and depression were not included in the study. The Standardized Mini MentalTest and the Montreal Cognitive Assessment Test (MoCA) were employed for thepurpose of measuring the cognitive functions. The NT-proBNP and MIC-1/GDF-15levels were examined with the ELISA method in the blood samples that were takensimultaneously from the patients (at the end of mid-week dialysis session).Results: The mean age of the patients was 48±2; and 58 (61.7%) of them were male,and 21.3% were diabetic. The mean duration of dialysis was 64±5 months. TheStandardized Mini Mental Test total score average of the patients was 26.7±0.1; and themean score of the MoCA Test was 20.1±0.4. It was seen that in a total of 77.7% of thepatients, there were impaired cognitive functions (MoCA total score <24). The SerumNT-proBNP average was 7326±590 ng/l; and the mean MIC-1/GDF-15 level was 13.1±0.8 ng/ml. The NT-proBNP level was positively correlated with MIC-1/GDF-15,urea, sodium and CRP levels; and negatively correlated with hemoglobin and albumin.Again, it was found that the NT-proBNP level had a significant and negative correlationwith the MoCA Test Delayed Recall and Total Score; and the Standardized Mini MentalTest had a significant and negative correlation with the Record Memory Score. Whenthe patients were divided into two groups according to NT-proBNP levels (above10.500 and below), it was observed that MoCA Test Total Scores were significantlydifferent from each other.Conclusion: The NT-proBNP levels are an indicator of hypervolemia in hemodialysispatients. The hypervolemia that exists in dialysis patients may cause the worsening ofthe cognitive functions. In the present study, we show that for the first time in theliterature, NT-proBNP levels are associated with cognitive functions in dialysis patients.There is a need for supportive studies in this field.Keywords: Hemodialysis, cognitive functions, NT-pro-BNP, macrophage inhibitorcytokine-1 (MIC-1/GDF-15)en_US
