Does platelet-delivered factor VIII provide limited resistance to anti-factor VIII inhibitors?
In FVIII(null) mice, pFVIII provides improved, but limited, protection in the presence of inhibitors of approximately 6-fold greater Bethesda Units per mL relative to infused FVIII. Our findings differ from a recent report using a tail-clip exsanguination assay on the degree of efficacy of pFVIII in the presence of inhibitors. We propose that this difference in outcome is as a result of the sensitivity of the tail-vein exsanguination model to low levels of pFVIII.
Thiamin supplementation reduced biochemical thiamin deficiency among Lao malaria patients following anti-malarial drug treatment, but it did not reduce the frequency of adverse events after anti-malarial therapy or have any detected clinical or parasitological impact.
