Abstract BACKGROUND: Our aim was to analyze the longitudinal changes in cardiac biomarker levels in hemodialysis patients with high comorbidity treated in our special hospital unit. We hypothesize that strict volume control strategy (salt-restricted diet, extended dialysis sessions and dry weight clinical assessment and reassessment in every session) could prevent progression of left-ventricular damage and, therefore, progressive increment in cardiac biomarker levels over time. METHODS: This is a longitudinal cohort study including 46 dialysis patients in which a strategy of strict volume control has been adopted. N-terminal pro-B-type natriuretic peptide (NT-proBNP), troponin T and C-reactive protein (CRP) levels were measured at baseline and prospectively at 4, 8 and 12 months. The possible association between volume control and cardiac biomarker levels was analyzed. RESULTS: Dry weight could be reduced (p < 0.01) over time. A reduction in systolic BP (p < 0.05) and in CRP levels (p < 0.05) was observed, whereas NT-proBNP and troponin T values remained stable. However, patients in the high quartile of NT-proBNP at baseline showed a reduction (p = 0.02) in troponin T over time with no significant trend (p = 0.08) to progressive reduction in NT-proBNP values. CONCLUSIONS: Strict volume control in dialysis patients may prevent progressive increment in cardiac biomarker levels over time. The impact seems to be higher among patients with higher levels at baseline in whom strict volume control can even reduce cardiac biomarker levels on follow-up.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
