This page is meant to cover regimens that are used in the context of acquired factor VIII inhibitors. See the inherited coagulopathy page for regimens relevant to inherited factor deficiency. In the future, we may add other acquired coagulopathy pages such as acquired vWD.

Guidelines

Given the rapid change in evidence in many areas of hematology/oncology, readers are encouraged to consider any guideline published 5+ years ago to be for historical purposes, only.

Cyclophosphamide & Prednisone

Regimen variant #1

Study Evidence
Shaffer et al. 1997 Case report

Note: Per Shaffer et al. 1997, "the lower ends of these ranges became the standard therapy to minimize side effects"

Immunosuppressive therapy

Continued until therapeutic response "Cyclophosphamide and prednisone were continued at full doses until the factor VIII inhibitor titer decreased to zero; after this, the doses of prednisone and cyclophosphamide were slowly decreased."


Regimen variant #2

Study Evidence
Bayer et al. 1999 Case report

Immunosuppressive therapy

Continued until therapeutic response, then prednisone and cyclophosphamide were tapered slowly


Regimen variant #3

Study Dates of enrollment Evidence
Green et al. 1993 Not reported Randomized, fewer than 20 pts (E-esc)

Preceding treatment

Immunosuppressive therapy
