In both groups each inhalation was preceded by premedication with disodium cromoglycate (DSCG) (40 mg). In Group A a significant decrease in symptoms score and in peak expiratory flow (PEF)-derived parameters was observed already after 3 months of treatment, and 2 patients lost the late component of the bronchial response to the challenge with HDM. No significant variation was found in bronchial responsiveness to methacholine and ultrasonically nebulized distilled water (UNDW) and in immunologic humoral and cellular parameters in peripheral blood after treatment in either group. No local important adverse reactions were observed in Group A and no systemic side effects were observed in either group. We conclude that LI is as effective as PI, but more rapid in its action, in the treatment of asthma due to HDM. Moreover, LI is locally well tolerated, providing DSCG is inhaled before each therapeutic inhalation, and does not induce systemic side effects.","tracks":[{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":388,"end":394},"obj":"HP_0002099"},{"id":"T2","span":{"begin":424,"end":429},"obj":"HP_0000618"},{"id":"T3","span":{"begin":1388,"end":1394},"obj":"HP_0002099"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"},{"subj":"T2","pred":"source","obj":"PubmedHPO"},{"subj":"T3","pred":"source","obj":"PubmedHPO"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"PubmedHPO","color":"#dc93ec","default":true}]}]}}
