Characteristics of the patients at the time of diagnosis

	No. of documented patients	No. or mean ± SD	% or range
Clinical cofactors
Sex: male	65	40	66
Age, y	54	68.1 ± 17.0	25-92
Preexisting conditions: cancer*	55	11	20
Survival at 12 mo	52	36	69.2
Standard biologic cofactors
FVIII activity in plasma, %	51	6.0 ± 10.9	0-59
Inhibitory titer toward FVIII, BU/mL†	65	66.9 ± 148.6	1-1050
FIX activity in plasma, %	18	117.5 ± 55.3	64-268
aPTT (measured/physiologic value)	37	2.4 ± 0.7	1.3-4.2

aPTT indicates activated partial thromboplastin time.

Other preexisting conditions were allergic drug reactions (5), autoimmune disorders (4), dermatologic disorders (3), diabetes (1), postpartum (2), and idiopathic (14).

†

Inhibitory titers were assessed using the modified Bethesda assay.
