Multisite management study of menorrhagia with abnormal laboratory haemostasis: a prospective crossover study of intranasal desmopressin and oral tranexamic acid.

The optimal management of menorrhagia among women with abnormal laboratory haemostasis is uncertain. In a crossover study, 116 women with menorrhagia [pictorial blood assessment chart (PBAC) score >100], negative gynaecological evaluation and abnormal laboratory haemostasis were randomly assigned to either intranasal desmopressin (IN-DDAVP) or tranexamic acid (TA) therapy for two menstrual cycles. The subjects then crossed over to the second study drug for two additional cycles.

Menorrhagia associated with laboratory abnormalities of hemostasis: epidemiological, diagnostic and therapeutic aspects.

Historically, the pathogenesis of menorrhagia has focused on anatomic and hormonal etiologies. However, in the past decade, numerous epidemiological studies have confirmed an association of von Willebrand factor (VWF) deficiency and menorrhagia with an incidence of VWF deficiency of 13% (95% CI, 11%, 16%). Such patients have a reduced quality of life and incur a high rate of seemingly unnecessary gynecological interventions.
