Laboratory evaluation typically reveals mild to moderate thrombocytopenia, unusually large platelets, and abnormal platelet function with absent or markedly reduced aggregation response to ristocetin.
There is a normal aggregation response to ADP agonists, collagen, adrenaline and arachidonic acid, but aggregation is absent with the addition of ristocetin.
Further investigations such as luteinizing hormone/follicle-stimulating hormone (LH/ FSH), Von Willebrand factor activity, and Ristocetin cofactor assay were done in selected patients.
Malyszko et al, in their study investigating the relationship between plasma and peritoneal fluid leptin levels with platelet aggregation by using ristocetin and arachidonic acid as agonists, found a positive correlation between these parameters.
Von Willebrand factor ristocetin cofactor (VWF: RCo) activity was measured with an in-house assay in a aggregometer (Chronolog Aggregometer 490) that measures the rate of aggregation of platelets in the presence of VWF and ristocetin.
Other assays in the HemosIL AcuStar VWF Assay Panel include: HemosIL AcuStar VWF Antigen (VWF:Ag) and HemosIL AcuStar VWF Ristocetin Cofactor (VWF: RCo) Activity.
To discriminate between these two variants, ristocetin induced platelet aggregation (RIPA) is used with a low dose of ristocetin to enhance platelet agglutination in the presence of gain-of-function mutations (25).
who took those studies into consideration, observed a reduced platelet aggregation response to collagen, ADP, adrenaline, ristocetin in patients with BTM and HBT compared to controls.
Many studies have shown that disintegrins are capable of inhibiting platelet aggregation induced by collagen, adenosine diphosphate (ADP), arachidonic acid, ristocetin, and thrombin [16, 21]
USA) was used, and adenosine diphosphate, arachidonic acid and ristocetin (Helena Inc.
In such cases, taking family history to reveal a recessive inheritance type and assays for vWF:Ag and ristocetin cofactor (RiCof) should be done simultaneously.
In the platelet aggregometry test, normal aggregation curves were obtained with collagen and ristocetin, near normal aggregation curves were obtained with adenozine diphosphate (ADP) and very low amplitude aggregation curves were obtained with epinephrine.
