Abstract

BACKGROUND: Less attention has been paid to evaluating subclinical cardiovascular disease (CVD) in the early stage of pediatric chronic kidney disease (CKD). Ambulatory blood pressure monitoring (ABPM) and arterial stiffness are the earliest detectable assessments of subclinical CVD. Asymmetric dimethylarginine (ADMA) is an analog of L-arginine (ARG) that inhibits nitric oxide (NO) production; thus the ARG-to-ADMA ratio (AAR) is an index of NO. Homocysteine (HCY) is a risk factor for CVD and it can be metabolized to L-cysteine (CYS). Given that HCY and ADMA/NO are closely linked and related to hypertension, we therefore investigated whether ARG and HCY metabolites, arterial stiffness parameters, ABPM profile, and left ventricular hypertrophy (LVH) are interrelated in children and adolescents with early CKD. METHODS AND RESULTS: This cross-sectional study included 57 pediatric patients with CKD stages 1-3. Two-thirds of the children with CKD stages 1-3 exhibited BP abnormalities accessed by ABPM. Children with CKD stages 2-3 had higher HCY, but lower CYS levels. The plasma HCY level was increased in children with LVH and abnormal ABPM. Systolic BP positively correlated with biomarkers AAR, HCY, and CYS. LV mass positively correlated with AAR, HCY, and CYS. CONCLUSIONS: BP abnormalities were prevalent and associated with AAR, HCY, and CYS in children with early CKD. Our data highlighted the effect of NO and the HCY pathway on CKD-related hypertension.

  • Deteriorated renal function correlates with altered markers of oxidative stress including mitochondrial oxidized LDL, homocysteine, and deficiency of reduced glutathione (GSH) and superoxide dismutase (SOD).

    “Deteriorated renal function correlates well with the altered markers of oxidative stress. These involve mitochondrial oxidized low-density lipoprotein (Garcia-Bello et al. 2014), homocysteine (Chien et al. 2015), and deficiency of reduced glutathione (GSH) and superoxide dismutase (SOD) (Garcia-Bello et al. 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
