At least 70% of asthmatic patients are woken from time to time by coughing, wheezing and breathlessness at night [1, 2]. The presence of nocturnal symptoms in patients with asthma denotes poor asthma control, and the concomitant overnight fall in peak flow correlates well with asthma severity [3]. It is important to enquire specifically about nocturnal symptoms in patients with asthma as many patients overlook these symptoms [4]. Epidemiological surveys suggest that the prevalence of nocturnal symptoms is as common in asthmatic patients attending general practitioners in the community as those attending hospital clinics [1, 4]. |
