Long-Term Outcome after Joint Bleeds in Von Willebrand Disease Compared to Haemophilia A: A Post Hoc Analysis.

Long-Term Outcome after Joint Bleeds in Von Willebrand Disease Compared to Haemophilia A: A Post Hoc Analysis. Thromb Haemost. 2018 Oct;118(10):1690-1700 Authors: van Galen KPM, Timmer M, de Kleijn P, Leebeek FWG, Foppen W, Schutgens REG, Eikenboom J, Meijer K, Fijnvandraat K, Laros-van Gorkom BAP, Twisk JW, Mauser-Bunschoten EP, Fischer K, WiN Studygroup Abstract Long-term outcome after joint bleeds in von Willebrand disease (VWD) (von Willebrand factor activity ≤ 30 IU/dL) could differ from moderate or severe haemophilia A (HA) (factor VIII [FVIII] 1-5 IU/dL or FVIII < 1 IU/dL). We performed a post hoc analysis on Haemophilia Joint Health Score (HJHS, 0-124), X-ray Pettersson scores (PS, 0-13/joint) and the Haemophilia Activities List (HAL, 0-100), using multivariable regression to adjust for age (rate ratio [RR] or odds ratio [OR] [95% confidence interval]). We included 48 VWD (median age, 47 years, type 3 VWD, n = 19), 39 moderate HA (median, 39 years) and 59 severe HA patients (median, 25 years) with documented joint bleeds. VWD patients suffered repeated bleeding (lifetime > 5/joint) less often than moderate and severe HA patients (52% vs. 77% vs. 98%). HJHS and PS in VWD were similar to moderate HA (median HJHS 5 vs. 6, RR 0.9 [0.5-1.4] and PS > 3 of ≥ 1 joint OR 0.3 [0.1-1.4]), but better than in severe HA patients (median HJHS 5 vs. 9, RR 1.8 [1.1-2.9]; PS > 3 in any joint OR 0.1 [0.0-0.3]...
