Pain assessment and management in Italian Haemophilia Centres
2021
BACKGROUND: Although the widespread use of factor VIII/IX replacement therapy has significantly reduced the severity of arthropathy in persons with haemophilia (PWH), some develop degenerative joint changes, associated with significant pain. The aim of this survey was to investigate the management and perception of pain among Italian physicians who treat PWH. MATERIALS AND METHODS: Between September and October 2017, a questionnaire was distributed to 35 Italian haemophilia treatment centres (60 physicians). RESULTS: Fifty-three haemophilia specialists completed the survey. We found that there was good agreement (98.1%) on the need to investigate pain at each clinical visit, but there was h…

Background Circulating dysfunctional factor IX (FIX) might modulate distribution of infused FIX in hemophilia B (HB) patients. Recurrent substitutions at FIX activation sites (R191-R226, >300 patients) are associated with variable FIX activity and antigen (FIXag) levels. Objectives To investigate the (1) expression of a complete panel of missense mutations at FIX activation sites and (2) contribution of F9 genotypes on the FIX pharmacokinetics (PK). Methods We checked FIX activity and antigen and activity assays in plasma and after recombinant expression of FIX variants and performed an analysis of infused FIX PK parameters in patients (n = 30), mostly enrolled in the F9 Genotype and PK HB …
