Reversible alopecia associated with high blood mercury levels and early menopause: a report of two cases.

OBJECTIVE
The aim of this study was to report on two women in early menopause with alopecia and high mercury (Hg) levels which reversed with a decrease in toxic levels.


METHODS
Retrospective chart review and case studies in a reproductive endocrinology practice.


RESULTS
A 43-year-old woman initially evaluated for early menopause later experienced sudden circumscribed hair loss on the scalp. Blood tests indicated elevated Hg levels and further investigation revealed a diet high in tuna. Levels fell with elimination of dietary tuna. Another woman, 39 years old was complaining of severe hot flashes, night sweats, and menstrual irregularity also developed alopecia. Treated unsuccessfully for low testosterone, blood tests indicated high Hg levels and simultaneous hair loss was observed; recommendation to alter diet, including fish intake, was followed by a reversal of alopecia, along with a decrease in blood Hg levels. Literature searches were conducted with a focus on Hg toxicity or poisoning with symptom of alopecia.


CONCLUSIONS
Women of reproductive age frequently seek treatment for what is thought to be hormone-related hair loss especially at menopause. Two women demonstrated a strong temporal correlation to high Hg levels associated with early menopause, which was reversible. The development of alopecia in the setting of mild Hg intoxication has not been reported in the medical literature despite its appearance in the popular press. Measurement of Hg levels should be considered in women with alopecia and its relationship to early menopause is unclear but bears further research.
