Figure 1.. Effects of FFP Administration and Anti-TNF Initiation in Patients with ADA2 Deficiency.
Panel A shows the half-life of adenosine deaminase 2 (ADA2) in 3 patients with a deficiency of this enzyme after an infusion of 100 ml of fresh-frozen plasma (FFP). Blood samples were drawn immediately after completion of the infusion and at 2 hours, 4 hours, and 6 hours after infusion, with values plotted after correction for the patient’s baseline ADA2 value. The median half-life was approximately 6.4 hours (range, 5.0 to 9.0). Panel B shows the cumulative number of strokes and recurrence rate in 15 study patients before and after the inhibition of tumor necrosis factor (TNF), according to the number of patient-months observed (P<0.001 by the likelihood ratio test). Panel C shows the number of strokes in the same 15 patients on the basis of matched follow-up time (733 patient-months) before and after anti-TNF therapy (P<0.001 by the Blyth–Still–Casella method).
