Quelques cas de thrombocytopénie et d'événements thrombotiques ressemblant au
SAPL ont été signalés chez des receveurs de vaccins contre la COVID-19 à base de
vecteur adénoviral. Cependant, l’association des aPL avec la vaccination COVID-19 n'est
pas claire. Dans notre étude la comparaison entre les 03 groupes : sujets atteins de
COVID-19 (n=106), sujets vaccinés (n=38) et témoins sains (n=70), a montré des taux
d’aPL : 40%, 84% et 19% respectivement. Nous avons constaté des valeurs hautement
significatives des taux d’aPL : chez les patients COVID-19 vs témoins (p=0.005/
OR=2.88), vaccinés vs témoins (p=10
-10
/OR=18.63), vaccinés vs patients atteints de
COVID (p=10
-5
/OR=6.48). Les sujets atteints de COVID-19 ont montré des valeurs
statistiquement significatives en positivité des Ac anti-B2GP1 IgM par rapport aux
vaccinés et des témoins sains (p=0.004, p=0.015 respectivement). Alors que les sujets
vaccinés ont montré des valeurs statistiquement très hautement significatives en positivité
d’aCL IgM par rapport à la population des patients atteints de COVID-19 et des témoins
sains (p=10
-9
, p=10
-12
respectivement). Ces considérations suggèrent que les aPL peuvent
représenter un facteur de risque d'événements thrombotiques après la vaccination contre
le COVID-19 et méritent des investigations supplémentaires. Abstract :A few cases of thrombocytopenia and APS-like thrombotic events have been reported in
recipients of adenoviral vector-based COVID-19 vaccines. However, the association of
aPL with COVID-19 vaccination is unclear. In our study, the comparison between the 03
groups: COVID-19 patients (n=106), vaccine receivers (n=38) and healthy controls
(n=70), showed aPL rates at : 40%, 84 % and 19% respectively. We found highly
significant values of aPL levels: in COVID-19 patients vs healthy controls
(p=0.005/OR=2.88), vaccine receivers vs healthy controls (p=10-10 /OR=18.63), vaccine
receivers vs COVID-19 patients (p=10-5/OR=6.48). COVID-19 patients showed
statistically significant values in anti-B2GP1 IgM positivity compared to vaccine receivers
and healthy controls (p=0.004, p=0.015 respectively). While vaccine receivers showed
very highly statistically significant values in aCL IgM positivity compared to COVID-19
patients and healthy controls (p=10-9, p=10-12 respectively). These considerations suggest
that aPL may represent a risk factor for thrombotic events after COVID-19 vaccination
and warrant further investigations. |
