ABSTRACT

Background:The lupus anticoagulant (LA) is one of the antiphospholipid antibodies (aPL); which prolong phospholipid- dependent coagulation tests by interfering with coagulation reactions that depend on protein - phospholipid complexes in vitro. Method: A 25 year old 'healthy' male Nigerian was screened for the presence of any coagulation abnormality using the KCT; PT and platelet count; after volunteering for his plasma to be used in the preparation of normal pooled plasma in a study. Results: He was disco- vered to have a prolonged KCT; PT and normal platelet count. Based on the prolonged KCT his plasma was subjected to mixing studies with various concentration of normal pooled plasma; the KCT index was calculated and a curve was plotted. His KCT index was 1.6 and the curve convex in the left axis suggesting the presence of LA. His past medical history and physical examination were not remarkable.Three months after the initial study; a repeat KCT index was 1.4 and the subject asymptomatic. Conclusion: From literature review this is the first report of LA in an asymptomatic adult Nigerian; the importance of this finding is discussed

ABSTRACT

Il s'agissait d'une femme âgée de 32 ans, aux antécédents de deux mort-nés en 2005 et 2006 et de zona brachial la même année. Elle était hospitalisée pour des nécroses des quatre derniers doigts de la main gauche dans un contexte de syndrome infectieux. Les anticorps anti VIH1 et anti-cardiolipine étaient positifs. Le bilan thrombophilique, les anticorps anti DNA natifs et anti ECT étaient négatifs. Quatre ans après le début du traitement par Combivir-névirapine avec ascension du taux de CD4, elle a développé une gangrène ischémique du membre inférieur droit par thrombose artérielle de la fémorale primitive homolatérale. Le dosage du lupus anticoagulant était successivement positif à un intervalle de 12 semaines. Le diagnostic de syndrome des anticorps anti-phospholipides secondaire à une infection par le VIH1 était retenu. Il n'existe pas ce jour de récidive sous anti-vitamine K
