PURPOSE: A combination therapy with inhaled corticosteroid (ICS) and a
long-acting ? agonist (LABA) is the standard treatment for asthmatic patients,
and step-down treatment is recommended once control has been achieved. However,
little data exist that evaluate the long-term outcomes after step-down treatment.
OBJECTIVE: To compare the long-term outcomes of step-down therapy with ICS/LABA
or ICS alone for asthmatic patients who have achieved well-controlled asthma by
the ICS (250 µg fluticasone)/LABA (50 µg salmeterol) combination (SFC, two puffs
per day). PATIENTS AND METHODS: We randomized 40 well-controlled patients with
asthma receiving SFC (250 µg) to two groups; one group of patients received
step-down therapy with low-dose SFC (100 µg, two puffs daily) and another group
of patients received step-down therapy with high-dose fluticasone propionate (FP)
alone (500 µg, daily). The two groups were monitored over 12 months for changes
in asthma control test scores, respiratory function (percent forced expiratory
volume in 1 second, maximal expiratory flow rate at 50% of the vital capacity
[%FEF50], and maximal expiratory flow rate at 25% of the vital capacity
[%FEF25]), and the concentration of fractional exhaled nitric oxide. RESULTS:
There was no significant difference in the dropout rate between the SFC and FP
groups. Low-dose SFC maintained the stability of all parameters over 12 months,
whereas the FP group exhibited a rapid 5% decrease in forced expiratory volume in
1 second within 2 months after discontinuation of salmeterol; furthermore, after
10 months, there was a gradual decrease in %FEF50 and %FEF25. CONCLUSION: This
study suggests that a balanced step-down protocol, including both ICS and LABA,
is essential in providing long-term stability to patients with mild-to-moderate
well-controlled asthma.
