Our aim is to analyse the differences in the prevalence of premenstrual asthma
(PMA) according to a set of criteria, the relationship between them and the influence of asthma
severity.
The answer ‘‘Yes’’ to ‘‘Does your asthma get worse before menstruation?’’ was considered
subjective PMA. A daily respiratory symptoms register of fertile asthmatic females was taken
during two consecutive menstrual cycles. For the semi-objective diagnosis, an exacerbation of
o20% was required in the symptoms register. Objective diagnosis was a premenstrual worsening
of o20% of peak flow.
We selected 103 patients. Subjective premenstrual deterioration was perceived in 43.7%. The
semi-objective deterioration of symptoms in the first cycle occurred in 44.7%, and in 22.3% in both
cycles. A total of 54.3% of females with semi-objective criteria in the first cycle perceived a
subjective deterioration of symptoms, versus 35.1% of those without semi-objective criteria
(p50.05). PMA was present at all levels of asthma severity, with no clear link to the degree of
severity.
The detection of PMA prevalence, the subjective perception of this deterioration and its
presence at all levels of asthma severity lead us to urge research into possible premenstrual
deterioration in all fertile asthmatic females
