Abstract

BACKGROUND:

The relationship between sex hormones and asthma has not been clarified. Studies have suggested a potential beneficial effect of exogenous sex hormones and/or contraceptive pills on asthma in premenopausal females whereas the data for postmenopausal females are inconsistent.

CASE REPORT:

A 33-year-old woman suffering from asthma with premenstrual exacerbations had a stable course until she began taking oral contraceptives. At that time she experienced clinical deterioration of her asthma associated with decline of pulmonary function tests. No other precipitating factors were identified. After discontinuing the contraceptives, her condition returned to baseline.

CONCLUSION:

We found only two reports of worsening of asthma related to hormonal therapy (estrogen in one case, contraceptive pills in the other) in premenopausal women. Our report, together with these observations, suggests that in some premenopausal women exogenous sex hormones and/or contraceptive pills may, contrary to expected, produce exacerbation of asthma.

PIP:

Although the mechanism of premenstrual asthma has not been established, hormonal variations during the menstrual cycle are believed to play an important role. About 30-40% of female asthmatics report worsening of asthma symptoms during the premenstrual and/or menstrual period. This article presents a case in which oral contraceptives (OCs) appeared to precipitate an asthma attack. The patient, a 33-year-old White US woman, first developed asthma at age 27 years. The strongest trigger to her asthma attacks was her menstrual period. All periods were associated with a worsening of asthma, typically extending from 1 week before to 2-3 days after the onset of menstrual bleeding. Subsequently, the patient's asthma was stabilized by continuous inhaled steroids. However, clinical deterioration of asthma and a decline of pulmonary function occurred immediately after the woman initiated OC use. There was a rapid stabilization in clinical status once OC use was discontinued. Although the weight of scientific evidence points to a possible beneficial effect of OCs or exogenous sex hormones on premenstrual asthma, this case suggests there may be a subset of women in whom sex hormones exacerbate asthma.
