This study aimed to evaluate our treatment policy based on the international consensus. Peak expiratory flow (PEF), dynamic spirometry and bronchodilation test results were therefore collected in 195 school-aged patients who visited our outpatient clinic in 1995. Sixty-four children (33%) used cromoglycate, 86 (44%) nedocromil and 45 (23%) inhaled steroids. Twenty-five (12%) needed combination therapy, mainly with salmeterol. Lung function results were good, and there were no significant differences between the therapeutic groups irrespective of whether pre- or postbronchodilator values were considered. PEF was decreased in eight (4%), forced expiratory volume in one second (FEVI) in four (2%) and maximum mid-expiratory flow (MMEF) in 33 (17%) patients. At least one result was decreased in 39 (20%) cases, in most cases (77%) MMEF alone. Significant rises after salbutamol inhalations were observed in 17 (9%) in PEF, in two (1%) in FEV1 and 20 (10%) in MMEF values. Thus, the bronchodilation test was positive in 33 (17%) cases, and in 22 (11%) cases it was the only sign of bronchial obstruction. Over 70% of the children with asthma can be treated with cromones by a stepwise treatment modality. Inhaled steroids can be restricted to those not controllable by cromones. Lung function tests, including postbronchodilator values, should be part of the follow-up of continuous maintenance medication for asthma.
