BACKGROUND: The acute onset of Heavy Menstrual Bleeding (HMB) during menses results in women seeking care in the Emergency Department. The current management of HMB among our residents uses combination oral contraceptives or oral progestins. The residents in the Emergency Department often send women home without any therapeutic intervention. There is no Regulatory Agency approved therapy for acute HMB. The etiology of HMB is not well understood. Two potential causes are changes in endometrial prostaglandins and increased fibrinolytic activity in the endometrium.
Specific Aim 1 is to investigate and compare the effect of oral estradiol compared to tranexamic acid in reducing blood loss and the duration of bleeding during an acute episode HMB.
Specific Aim 2 is to evaluate the effect of estradiol and tranexamic acid on possible causes of the acute HMB by measuring prostaglandins and Plasminogen activator in menstrual effluent at the end of treatment.
METHODS: This is a randomized, double-blind, controlled, parallel-group, non-inferiority trial, with participants between the ages 18 and 45 years, with acute cyclic heavy menstrual bleeding enrolled during an emergency room visit. Participants are randomized to receive 48 hours' treatment with 1.3 mg oral tranexamic acid or 1.0 mg oral estradiol three times a day. The primary endpoint is reduction in the amount of menstrual effluent. Sample size was calculated based on detecting less than 30 ml difference between the mean menstrual blood loss of the two treatment groups. Amount of blood loss is quantified by alkaline hematin method on extraction of menstrual pads and tampons. Secondary outcome is the variation of hemostatic factors in the menstrual effluent in two treatment groups by collecting menstrual effluent and quantitating prostaglandins, Plasminogen activators, Plasminogen activator inhibitors, and vascular endothelial growth factor.
ANTICIPATED OUTCOMES: The investigators anticipate a reduction in mean menstrual blood loss in both treatment groups. Compared with participants treated with estradiol, the group treated with tranexamic acid will not have statistically significant change in reduction of menstrual effluent. We also anticipate changes in different local hemostatic factors in menstrual effluent specific to the treatment arm.
