Intrapatient consistency for A-IPF and platelet count responses to anti-D and IVIG. (A) A-IPF and platelet count responses on 2 consecutive treatment episodes with intravenous anti-D in the same ITP patient. One line graph has a y-axis representing platelet count, and the other represents A-IPF, against an x-axis representing time. Dramatic increases in platelet counts with minimal corresponding increase in A-IPF, in response to anti-D treatment, are shown. This response was consistent for 2 consecutive treatment episodes in the same patient. (B) A-IPF and platelet count responses on 3 consecutive IVIG treatment episodes in the same ITP patient. One line graph has a y-axis representing platelet count, and the other represents A-IPF, against an x-axis representing time. The platelet count and A-IPF increased substantially after each IVIG administration. The platelet count and A-IPF responses to IVIG for this patient were consistent for all 3 treatment episodes.
