Abstract

Angioedema (AE) is a rare but potentially life-threatening side effect of therapy with inhibitors of angiotensin-converting enzyme (ACE), the main bradykinin (BK)- inactivating metallopeptidase in humans. The pathogenesis of ACE inhibitor (ACEi)- associated AE (AE+) is presently unknown, although there is increasing evidence of a kinin role. We analyzed the metabolism of endogenous BK (B(2) receptor agonist) and its active metabolite, des-Arg(9)-BK (B(1) receptor agonist), in the presence of an ACEi during in vitro contact activation of plasma from hypertensive patients (n = 39) who presented AE+. Kinetic parameters were compared with those measured in a control group (AE-) of hypertensive patients (n = 39) who never manifested any acute or chronic side effects while treated with an ACEi. The different kinetic parameters were analyzed using a mathematical model (y = k t(alpha) e(-beta t)) previously applied to a normal, healthy population. The slope of BK degradation, but not its formation from high-molecular-weight kininogen, was lower in AE+ patients when compared with the AE- controls. des-Arg(9)-BK accumulation during the kinetic measurements was significantly higher in AE+ plasma. This accumulation of the B(1) agonist in AE+ patients paralleled its half-life of degradation. In conclusion, our results show, for the first time, that an abnormality of endogenous des-Arg(9)-BK degradation exists in the plasma of patients with ACEi-associated AE, suggesting that its pathogenetic mechanism lies in the catabolic site of kinin metabolism.

  • APP activity and des-Arg9-bradykinin degradation are decreased in the sera of angioedema patients of European origin compared with control subjects.

    “Supporting this notion, APP activity and des-Arg 9 -bradykinin degradation are decreased in the sera of angioedema patients of European origin compared with control subjects.13,14”

    From Dipeptidyl Peptidase IV in Angiotensin-Converting Enzyme Inhibitor–Associated Angioedema (2008) · cites this paper as [14]

    The Discussion reports slower des-Arg9-bradykinin degradation in angioedema patients than controls and cites prior observations of decreased APP activity in the same patients. However, the Blood Samples section says this study tested plasma, not serum, and the Patients section describes participants as white without establishing European origin. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Plasma APP activities are significantly lower in patients with a history of AE-ACEi, and this is strongly correlated with a significant decrease in des-Arg9-bradykinin degradation in vitro.

    “We previously reported significantly lower plasma APP activities in patients with a history of AE-ACEi, which is strongly correlated with a significant decrease in desArg 9 -BK degradation in vitro (Blais et al. 1999 a ; Adam et al. 2002; Molinaro et al. 2002).”

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.
