Medication Summary

Most patients with May-Hegglin anomaly (MHA) do not have clinically significant problems with bleeding and do not require treatment. Corticosteroids and splenectomy are ineffective. On the rare occasions when patients have severe bleeding, platelet transfusions may be required. Prophylactic platelet transfusions are not routinely used before surgery and delivery. Intravenous desmopressin has been used preoperatively,[13] although the mechanism of action is uncertain.[23]

Class Summary

Use of desmopressin, a synthetic analogue of vasopressin, may be used before surgery.

Desmopressin acetate (DDAVP)

 

Releases von Willebrand protein from endothelial cells. Improves bleeding time and hemostasis in patients with some vWf (mild and moderate von Willebrand disease without abnormal molecular forms of von Willebrand protein). Effective in uremic bleeding. Tachyphylaxis usually develops after 48 h, but the drug can be effective again after several days. Nasal solution available as 0.1 mg/mL (10 mcg/0.1 mL).

Blood smear (original magnification X2000) in a patient with May-Hegglin anomaly (MHA) demonstrates a characteristic giant platelet with poorly defined granulation. A normal-sized platelet is also present. The trilobed neutrophil contains a large, well-defined, basophilic, peripherally placed cytoplasmic inclusion body (resembling a Döhle body).
