Abstract

Introduction: Myeloperoxidase (MPO), an enzyme linking obesity and cardiovascular (CV) risk in adults, has rarely been studied in young children and no studies assessed its association with renal function. We sought to explore a possible association between serum MPO levels, obesity, CV risk factors and renal function in prepubertal children. Materials/Methods: Cross‐sectional evaluation of 309 children aged 8–9 years (161 normal weight, 148 overweight/obese), members of the birth cohort Generation I (Portugal). Anthropometrics (body mass index (BMI), waist‐to‐height ratio (WH tR) and % body fat mass (%BFM) by bioelectrical impedance analysis), 24‐h ambulatory blood pressure monitoring and pulse wave velocity (PWV) were measured. Insulin resistance was estimated by the HOMA index (considering serum fasting glucose and insulin determinations). Serum MPO levels were assessed by immunoenzymatic assay. Results: MPO levels were positively associated with obesity indices (BMI z‐score, WH tR and %BFM). Higher MPO levels were associated with higher 24‐h and night‐time mean arterial pressure, with nondipping and with higher values of insulin resistance. In normal weight children, the endothelial function, as evaluated indirectly by PWV, was an independent predictor of MPO levels. In overweight/obese children, estimated glomerular filtration rate increased significantly across tertiles of MPO (Ptrend = 0·031) and this association held after adjustment for age, sex, neutrophil and monocyte counts and CV risk factors. Conclusions: Our results reinforce the role of MPO as a risk marker in obesity and related CV morbidities in young children. MPO levels associate with the dipping pattern and PWV and, among overweight/obese children, an association exists between MPO and renal function.

  • HOCl is responsible for renal dysfunction among obese children, who show positive correlation between 8-iso-PGF2α and blood lipids, serum MPO, and insulin resistance.

    “HOCl has been found to be responsible for renal dysfunction among obese children. These children have shown a positive correlation between an isoprostane 8-iso-prostaglandin F2α (8-iso-PGF2α) and blood lipids, serum levels of MPO, and insulin resistance (Yu et al. 2013; Correia-Costa et al. 2016).”

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.
