Abstract

The management of anticoagulant therapy (OAT) in patients with factor VII (FVII) deficiency is a very challenging clinical issue, as warfarin further reduces FVII levels, thus potentially increasing bleeding risk. On the other hand, the International Normalized Ratio test is misleading in such patients, as they do not reflect the actual level of global inhibition of the coagulation system. We report here three cases of patients with a moderate FVII deficiency and receiving direct oral anticoagulants (DOAC) for prevention of cardioembolism in atrial fibrillation. Of note, two of them experienced a treatment failure while on warfarin, while DOAC treatment was not associated with thrombotic or hemorrhagic adverse events. DOAC are very attractive for the management of OAT in FVII deficient patients, because they do not require monitoring by tests affected by the inherited defect, and their mechanism of action is FVII-independent.

Nebál bych se primárně běžné dávky DOACs, nebot hladiny FVII kolem 30-50% by nemely být symptomatické. Snížit ji je možné vždy, bude li to třeba. Já sám bych asi vybral apixaban, protože podle nekterých udaju ma nižší risiko krvácení, ale nejsou na to podle mne přesvědčivá data. Sám se těším na názory kolegů.

Dobrý den,

Hladina F VII umožnuje standardní dávku DOACs, pokud nejsou jiné limity /ren.fce aj./ Já osobně bych mu dal Eliquis 5 mg 1-0-1. Pokud by chtěl 1x denně, tak Lixianu 60 mg. Pokud by bylo nutné, tak lze snížit /jak píše pan docent/ na 2x2,5 mg či Lixianu 30 mg.
S pozdravem P.D.

Souhlasím s kolegy bez připomínek.
