AUB and HRT
Abnormal uterine bleeding (AUB) with HRT is
unscheduled bleeding.
It affects around 40 to 60% on combined HRT.
Commonly leads to discontinuation of the
therapy.Hickey M. Maturitas 2009.

AUB and HRT
AUB occurs with cyclical and continuous combined
regimens.
38% on sequential and 41% on combined HRT in one year.
12% and 20%, respectively require endometrial biopsy.
Ettinger B. Fertil Steril 1998

AUB and HRT
Unscheduled bleeding is most common in the initial months and tends to settle with long-
term use.

Mechanisms of endometrial bleeding and combined HRT
•wide range of combined HRT•varying prescribing schedules•no correlation between endometrial histology with the type or dose of HRT•individual variations in response to the same HRT

AUB and HRT
•poor compliance•systemic or pelvic pathology•40% of women with endometrial polyps and sub mucus fibroids•in the majority - no pathological cause for the bleeding

users will have no intrauterine pathology.

Management of AUB
• transvaginal ultrasonography• saline infusion sonohysterography• the gold standard is hysteroscopy with
endometral biopsy• no evidence that changing the estrogen
or progestogen or the mode of delivery are effective
•lack of consensus•persistent bleeding•when to reinvestigate?

AUB and HRT
1. Normal uterine cavity (50.4%)
2. Abnormal uterine cavity:• endometrial polyps (36.8%),• myomas (10.2%)3. Intracervical pathology:• cervical polyp (2.6%)
![Page 32: O ffice hysteroscopy in postmenopausal women on HRT with uterine bleeding](https://reader036.fdocuments.in/reader036/viewer/2022062518/568146b9550346895db3e4bf/html5/thumbnails/32.jpg)
The incidence of significant pathology in patients with AUB on HRT is very low. However benign polyps are common.
The gold standard for investigation of AUB is HSC with endometrial biopsy, if AUB continues after 6 months of HRT or if it
recurs after amenorrhea
