Premenstrual asthma was found in 40 patients (42.1%). It is more common between 16 and 35 years of age (Figure 1) with an average age of 34.78 ± 8.97 years (Table 1). There was no significant difference in average age between those who have and those who do not have premenstrual asthma (Table 1). The symptoms of premenstrual asthma are represented almost exclusively by an increase in dyspnea re-Summary Introduction: Premenstrual asthma (APM) is often confused by the patient and/or doctor with the symptoms of asthma in general. The purpose of our study is to investigate the clinical and spirometric characteristics of APM. Materials and method: Prospective descriptive study from 2011 to 2017, on 95 non-menopausal asthma patients, divided into 2 with and without APM. They benefited on a single menstrual cycle of spirometry during the follicular phase, luteal and premenstrual and cutaneous tests. Results: APM is found in 42.1% of cases. It is more common between 16-35 years old. The main symptom is dyspnea in 97.5% of cases. Premenstrual syndrome is present in 92.5% of APM. No relationship was found between the severity of asthma and APM (P = 0.41). In contrast, uncontrolled asthma is more common in women with APM (75%). No difference in the spirometry of the 3 phases of the cycle between the 2 groups. In case of APM, the CV is higher during the luteal and premenstrual phases and the PEF is decreased during the premenstrual phase and this in 60% of the cases. Conclusion: The results on a single menstrual cycle reinforce the hypothesis of the role of sex hormones in APM.
