Many individuals with vWD type 2A have a response to DDAVP, with peak vWF and FVIII levels at 30-60 minutes. This is similar to responses observed in patients with vWD type 1. However, rapid loss of vWF, FVIII, and particularly ristocetin cofactor (RCoF) activity occurs as the high-molecular-weight multimers are degraded, with return to baseline levels at 4 hours post infusion. Although the response is transient, it may be adequate therapy in certain clinical situations.
