Physical activity and bleeding outcomes among people with severe hemophilia on extended half-life or conventional recombinant factors.

ABSTRACT:

Background

Few have assessed physical activity (PA) and annual bleed rates (ABRs) among people with hemophilia on extended half-life (EHL) factors (recombinant factor VIII Fc [rFVIIIFc]/recombinant factor IX Fc [rFIXFc]) and conventional factors (recombinant factor VIII [rFVIII]/recombinant factor IX [rFIX]).

Objective

To assess changes in PA and ABR at consecutive annual visits in individuals with severe hemophilia A and B (HA/HB) on prophylactic treatment with rFVIIIFc/rFIXFc versus rFVIII/rFIX.

Patients/methods

We conducted a retrospective chart review of 344 people with severe HA/HB (ages 6-35) receiving prophylaxis with rFVIIIFc/rFIXFc (EHL factors) or rFVIII/rFIX (conventional factors) for ≥6 months in 2014-2015. Differences in changes in outcomes from 2014 to 2
