“…The diagnosis of bleeding risk is clinically important in preparing patients before surgery or delivery. The current recommendations in patients with GD include performing a complete history of bleeding tendency (including easy bruising and recurrent gum or nose bleeds, and heavy menstrual bleeds), a complete blood count, coagulation factors assays if the prothrombin time and/or partial thromboplastin time are abnormal, platelet aggregation tests, and von Willebrand factor levels and activity (Ioscovich et al , 2005; Zimran et al , 2005). Platelet adhesion studies are currently used in the Gaucher Clinic, Shaare Zedek Medical Centre, as part of the routine check of the haemostatic system before surgical procedures or delivery.…”

Summary Patients with type I Gaucher Disease (GD) may have a clinically significant bleeding tendency that is disproportionate to their platelet count. We hypothesized that impaired platelet adhesion might contribute to bleeding tendency. Adult patients with type I GD with platelet counts ≥130 × 109/l and haematocrit ≥30% (n = 48), obligatory carriers (n = 52), and healthy controls (n = 19) were studied. Platelet adhesion, using the IMPACT‐R (Cone and Plate(let) Analyser), and platelet aggregation were determined. Type I GD patients had significantly lower platelet adhesion [surface coverage %, median (interquartile range)] 4·6 (3·2–7·5), compared to controls, 8·7 (7·6–10·3), or carriers, 8·1 (6·5–9·4; P = 0·001). Platelet adhesion was not affected by the use of disease‐specific enzyme replacement therapy but was improved in patients after splenectomy, 7·2 (5·8–9·3). Mixing tests showed that the reduced adhesion was an intrinsic platelet defect. Mucosal bleeding was reported in 17 (35·4%) patients and was associated with abnormal adhesion [P = 0·037, with an Odds Ratio (95% confidence interval) of 5·73 (1·1–29·6)]. Five patients (22%) had reduced platelet aggregation, all of whom had reduced platelet adhesion. Platelet aggregation defect was not associated with mucosal bleeding. In conclusion, platelet adhesion defect is a major thrombocytopathy in type I GD patients and can explain part of the increased tendency to bleeding.
