Abstract

There is a unique relationship between the kidney and blood pressure (BP): on the one hand, renal dysfunction and particularly renal disease cause an increase in BP, while on the other hand, high BP accelerates loss of function of the diseased kidney. Transplantation studies, both in experimental animals and humans, documented that "blood pressure goes with the kidney," a normotensive recipient of a kidney genetically programmed for hypertension (HT) will develop HT, while conversely hypertensive patients with renal failure receiving the kidney of a normotensive donor may develop normotension. Family studies showed higher BP values and more frequent HT in first degree relatives of patients with primary glomerulonephritis or diabetic nephropathy, both type 1 and type 2. The notion that HT accelerates the loss of renal function has been proposed at the turn of the century, but definite evidence by observational and interventional studies has only been provided in the last two decades. The issue has been much confounded by the mistaken believe that damaged kidneys require higher BP values in order to function properly. The mechanisms of BP increase in renal disease comprise: salt retention, inappropriate activity of the renin-angiotensin system (RAS) and of the sympathetic nerve system as well as impaired endothelial cell-mediated vasodilatation. There is ample evidence both in primary renal disease (AIPRI and REIN trials) and in nephropathy of type 1 and type 2 diabetes (IDNT, RENAAL) that pharmacological blockade of the RAS by angiotensin-converting enzyme inhibitors or angiotensin II type 1 receptor blockers has BP-independent renoprotective effects. More recently, it has also been shown that blockade of the sympathetic nerve system has BP-independent effects on albuminuria and on glomerulosclerosis.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Sympathetic activation aggravates existing hypertension, proteinuria, interstitial fibrosis and glomerulosclerosis.

    “Sympathetic activation aggravates existing hypertension, proteinuria, interstitial fibrosis and glomerulosclerosis104.”
  • Sympathetic activation is present in the early phases of renal disease, in the absence of uremia, being seen in patients with nephrotic syndrome and with autosomal dominant polycystic kidney disease despite normal renal function, and increases with disease progression.

    “Sympathetic activation is present in the early phases of renal disease, in the absence of uremia, being seen in patients with nephrotic syndrome and with autosomal dominant polycystic kidney disease despite normal renal function, and increases with disease progression103.”
  • In rats with 5/6 nephrectomy, the hypertension and sympathetic activation are abolished by dorsal rhizotomy, which abolishes renal afferent nerve input to the central nervous system.

    “These clinical observations have a parallel in experimental studies in rats with 5/6 nephrectomy103, where the hypertension and sympathetic activation in this renal failure model is abolished by dorsal rhizotomy, which abolishes renal afferent nerve input to the central nervous system.”

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.
