Relationship between serum albumin and pulse wave velocity in patients on continuous ambulatory peritoneal dialysis
Open accessAbstract
BACKGROUND: Hypoalbuminemia is a risk factor for cardiovascular events and mortality in dialysis patients, but the underlying mechanism remains unclear. Meanwhile, increased pulse wave velocity (PWV), the marker of arterial stiffness, has been proved to be an independent predictor of cardiovascular disease. The relationship between serum albumin and PWV in continuous ambulatory peritoneal dialysis patients (CAPD) was studied. METHODS: Sixty-two CAPD patients were studied. The average age was 63 +/- 12 years and dialysis duration was 23 +/- 22 months. Serum albumin, C-reactive protein (CRP), and carotidfemoral PWV were measured. RESULTS: Among these patients, 43.5% were men. The mean serum albumin concentration was 37 +/- 4 g/L and PWV was 11.9 +/- 2.3 m/s. PWV positively correlated with age (r = 0.35, P < 0.01), diabetes (yes=1, no=0; r = 0.292, P < 0.05), systolic blood pressure (SBP; r = 0.493, P < 0.001) and CRP (r = 0.295, P < 0.05), but negatively correlated with serum albumin (r = -0.357, P < 0.01). In multiple regression analysis, SBP (beta = 0.615, P < 0.001), age (beta = 0.414, P < 0.01), albumin (beta = -0.315, P < 0.05) and total cholesterol (beta = 0.275, P < 0.05) were independent determinants of PWV. In a non-inflamed subgroup (CRP < 3 mg/L, n=30), albumin still negatively correlated with PWV (r = -0.66, P < 0.001). CONCLUSION: Serum albumin inversely correlated with increased PWV in CAPD patients, suggesting that increased arterial stiffness might be the link between hypoalbuminemia and increased cardiovascular mortality in dialysis patients.

More severe inflammation is associated with progressively lower serum albumin levels, although the strength of the correlation has only sparsely been investigated.

From Hypoalbuminemia: Pathogenesis and Clinical Significance (2019) · cites this paper as [24]
The Methods identify CRP as an inflammation marker, but the Results report correlations of CRP and albumin with pulse wave velocity—not with each other. The subgroup analysis examines albumin and pulse wave velocity in patients without inflammation. Our copy does not establish that increasing inflammation corresponds to progressively lower albumin or discuss how extensively that correlation has been investigated. (LLM, conf=0.74)

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.
