Can climacteric women self-adjust therapeutic estrogen doses using symptoms as markers?
OBJECTIVE
To investigate if disappearance of climacteric symptoms during hormone replacement therapy (HRT) also means good therapeutic level of serum estradiol. The study group comprised of 32 postmenopausal women who had frequent climacteric symptoms.


METHODS
The women increased the daily treatment doses of percutaneous estradiol every 2 weeks until they felt comfortable with it. Each woman continued at that treatment dose for up to 3 months. Blood samples for estradiol assay were drawn at baseline, every time before the estradiol dosage was increased and at the end of the study. Climacteric symptoms were scored according to the Kupperman menopausal index.


RESULTS
Despite the relief of climacteric symptoms, serum estradiol concentration was at a menopausal level (< 50 pg/ml) in 22% of the women. In all, 45% of the subjects showed serum estradiol remaining under 60 pg/ml, 29% of the women showed levels of 60-100 pg/ml and 26% showed serum estradiol concentration more than 100 pg/ml.


CONCLUSIONS
The disappearance of climacteric symptoms during HRT does not guarantee that estrogen levels are sufficiently high for obtaining long term benefits of HRT.
