Does persistent hyperprolactinemia contribute to bone loss independently of estrogen deficiency in postmenopausal women?
Authors' conclusion
Persistent hyperprolactinemia is associated with lower lumbar spine BMD in postmenopausal women with prolactinoma.
Study context
- Population
- Postmenopausal women with prolactinoma diagnosed during the premenopausal period, drug-free follow-up
- Participants
- 42 women
- Exposure
- Hyperprolactinemic vs normoprolactinemic
- Outcome
- BMD by DXA at lumbar spine and femoral neck
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Lumbar spine BMD
P = 0.022
Observational data: associations, not effects.
Further findings
Prolactin exposure and cabergoline treatment
- Hyperprolactinemic patients had longer cumulative exposure to hyperprolactinemia and required longer, higher-dose cabergoline
Baseline prolactin for identifying osteoporosis
- Baseline prolactin higher in patients with osteoporosis; AUC
- 0.861
Correlation of prolactin with lumbar spine bone mineral density (BMD) and T-scores
- Lumbar spine BMD and T-scores inversely correlated with prolactin levels
Multivariable analysis of low BMD
- Baseline prolactin level remained independently associated with low BMD
