Abstract

Abstract—In a previous report by Freedman et al (J Clin Invest.1996;97:979–987), plasma from 2 brothers with stroke or transient ischemic attack inactivated the antiplatelet effects of nitric oxide (NO), and this effect was found to be a consequence of a deficiency of plasma glutathione peroxidase (GSH-Px). In this study, we attempted to define the generalizability of this deficiency by studying NO-mediated antiplatelet effects in 7 families with familial childhood stroke. Seven families with familial childhood stroke that consecutively presented to a large referral center were included in the study. We monitored ADP-induced aggregation of normal gel-filtered platelets (GFP) in platelet-poor plasma (PPP) from normal individuals and from patients in the presence or absence of an NO donor (S-nitroso–glutathione). Surface P-selectin expression of normal GFP in patients’ PPP was analyzed by flow cytometry after incubation with a P-selectin–specific monoclonal antibody in the presence or absence of the NO donor. We also measured GSH-Px activity in plasmas from family members and normal controls using standard methods. In 6 of 7 families, NO failed to inhibit platelet P-selectin expression and platelet aggregation in PPP from the affected family members and some of their relatives. Of 4 families studied, 3 probands and their corresponding affected parent had 50% decrease in plasma GSH-Px activity. In some patients with childhood stroke, impaired metabolism of reactive oxygen species as a result of reduced GSH-Px activity results in NO insufficiency that affects normal platelet inhibitory mechanisms and predisposes to arterial thrombosis.

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.
