Mots-clés: | 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.

Résumé: | 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.
