Menstruation has been suggested as a possible trigger of near-fatal asthma (NFA), but the evidence supporting this association remains weak. We sought to assess the role of menstruation as a contributing factor in the development of NFA episodes in women of reproductive age.

Forty-four female patients of reproductive age with near-fatal attacks were enrolled in a multicenter study. Data on patient and clinical characteristics were collected. We also performed spirometric and allergy studies when the patients were in stable condition.

Significantly more NFA episodes were observed on the first day of menstruation (11 [25%] patients) than on the remaining days (33 [75%] patients, P = .022), and patients who presented for care on the first day of menstruation used more inhaled salbutamol as rescue medication (9 [9.5] vs 1.8 [3.7] μg/d during the 7 days before the asthma exacerbation, P = .003).
Menstruation might act as a contributing factor in the development of NFA episodes in patients with unstable asthma. Specific recommendations should be included in educational programs, and the self-management plans of asthmatic women of reproductive age should include the systematic recording of their asthma symptoms and pulmonary function in the perimenstrual phase.
