Abstract

OBJECTIVE:

To determine causes of death, estrogen toxicity, and hyperprolactinemia in a murine model of systemic lupus erythematosus (SLE).

METHODS:

Female New Zealand Black x New Zealand White (NZB x NZW) mice were implanted with ethinyl estradiol, 17 beta-estradiol, or empty capsules (controls).

RESULTS:

Estrogen-treated mice developed striking hyperprolactinemia and died prematurely with genitourinary complications.

CONCLUSION:

Implanted estrogens, including 17 beta-estradiol in a dose reported previously to stimulate SLE, contribute to premature death in NZB x NZW mice, through toxic effects. Estrogen therapy increases the level of prolactin, an immunostimulatory hormone.
