Tranexamic acid, an antifibrinolytic frequently beneficial for menorrhagia, epistaxis, and mucosal bleeding, which is the most prevalent type of bleeding.Continuous factor infusion may be necessary for patients who do not respond clinically and who are unable to maintain appropriate factor levels with intermittent infusions.[26] Targeting both FVIII and vWF activity levels of greater than or equal to 0.50 IU/mL for at least three days after major surgery is advised by the 2021 guidelines on managing vWD from the American Society of Hematology (ASH), International Society on Thrombosis and Haemostasis (ISTH), National Hemophilia Foundation (NHF), and World Federation of Haemophilia (WFH).Interestingly, injected vWF has a brief half-life in avWS, particularly in patients with avWS linked to inhibitors or MGUS.[25]To ascertain the half-life of the infused products, levels of vWF:RCo and FVIII activity must be measured both before and soon after the infusion.Tranexamic acid (500 mg tabs) tds orally for 5-7 days at a dose of 25 mg/kg/dose (maximum: 1.5 g/dose).Desmopressin (DDAVP) When there is proof in the medical record of a safe and adequate response, patients with mild to moderate Type 1 vWD may be treated with desmopressin (Desmopressin challenge).Administration: via subcutaneous injection or intravenous infusion Intravenous infusion: dilute with 0.9% sodium chloride to a final volume of 50 mL, then infuse for at least half an hour.Because of its increased concentration, Octostim(R) is recommended for subcutaneous injection.For dosage modifications and intervals, careful observation of clinical response and vWF activity measures is necessary. After injection, the half-life of FVIII:C is around double that of vWF Ag.20-24 hours compared to 10-14 hours)), ascribed to the endogenous rise in FVIII levels, which the additional exogenous vWF infusion stabilizes.Factor generated from plasma If desmopressin fails to stop bleeding, a replacement of VIII/vWF (Biostate(R)) may be necessary.Presentation: Minirin(R) (4 micrograms/mL) and Octostim(R) (15 micrograms/mL).

may be administered either on its own or in addition to desmopressin/factor concentration.
Tranexamic acid (500 mg tabs) tds orally for 5-7 days at a dose of 25 mg/kg/dose (maximum: 1.5 g/dose).Desmopressin (DDAVP) When there is proof in the medical record of a safe and adequate response, patients with mild to moderate Type 1 vWD may be treated with desmopressin (Desmopressin challenge). Desmopressin challenges are conducted at the RCH starting at age 5. Effective in Type 2 vWD on occasion, but ineffective in Type 3 vWD. The level of Factor VIII/vWF should grow by two to three times. Due to recorded cases of hyponatraemia and seizures, it is generally not advised for young children (less than three years old). Children with a history of seizure disorders should not use this medication. In the 24 hours after desmopressin administration, fluid restriction (2/3 maintenance daily fluid requirement) is advised. Dosage:0.3 micrograms/kg (up to 20 micrograms) stat Give 30 minutes prior to surgery if necessary. Up to three dosages per day could be taken into consideration. After 48 hours, tachyphylaxis might be an issue. Factor generated from plasma If desmopressin fails to stop bleeding, a replacement of VIII/vWF (Biostate®) may be necessary. Administration: via subcutaneous injection or intravenous infusion Intravenous infusion: dilute with 0.9% sodium chloride to a final volume of 50 mL, then infuse for at least half an hour. After a subcutaneous injection, apply pressure to the injection site for one to two minutes. Presentation: Minirin® (4 micrograms/mL) and Octostim® (15 micrograms/mL). Because of its increased concentration, Octostim® is recommended for subcutaneous injection.For dosage modifications and intervals, careful observation of clinical response and vWF activity measures is necessary. FVIII:C, vWF antigen (vWF Ag), and vWF:RCo are the usual parameters that must be tracked. The main purpose of the FVIII:C and vWF:RCo tests is to track replacement therapy. In patients with severe bleeding episodes or prior to major surgery, the overall objective is to maintain the activity of FVIII and vWF (usually assessed as vWF:RCo) between 50% and 100% for three to fourteen days. Interestingly, injected vWF has a brief half-life in avWS, particularly in patients with avWS linked to inhibitors or MGUS.[25]To ascertain the half-life of the infused products, levels of vWF:RCo and FVIII activity must be measured both before and soon after the infusion. After the initial infusion, levels should be evaluated at 4, 8, and 12 hours to determine the half-life. Depending on the patient's response and clinical situation, additional spaced-out testing should then be carried out every 12 to 24 hours. Plasma levels of FVIII:C and vWF:RCo must be measured every 12 hours on the day of surgery and then every 24 hours after major procedures. Since elevated FVIII levels raise the risk of thrombosis, it is essential to monitor FVIII activity to make sure it stays below 200 IU/dL. After injection, the half-life of FVIII:C is around double that of vWF Ag.20-24 hours compared to 10-14 hours)), ascribed to the endogenous rise in FVIII levels, which the additional exogenous vWF infusion stabilizes. Continuous factor infusion may be necessary for patients who do not respond clinically and who are unable to maintain appropriate factor levels with intermittent infusions.[26] Targeting both FVIII and vWF activity levels of greater than or equal to 0.50 IU/mL for at least three days after major surgery is advised by the 2021 guidelines on managing vWD from the American Society of Hematology (ASH), International Society on Thrombosis and Haemostasis (ISTH), National Hemophilia Foundation (NHF), and World Federation of Haemophilia (WFH). According to the guidelines, it is not recommended to use just FVIII levels more than or equal to 0.50 IU/mL as a target during this time.[27]
