AIM: Steroid-sparing effect of sublingual immunotherapy (SLIT) in mono/polisensitized asthmatic children were evaluated.MATERIALS AND METHODS: Children undergoing allergen-specific SLIT between 2010 and 2014 were included. Asthma control and usage/dose of inhaled corticosteroid (ICS) in the previous year was determined. Asthma control without ICS need ?6 months was defined as 'ICS avoidance'.RESULTS: 90 children (mean ± SD age 8.92 ± 4.17 years) were enrolled, 56.7% (n = 60) being polysensitized. Mono, 2-simultaneous and multiple-pollen-mix allergen SLIT were prescribed in 84.4, 17.8 and 7.8%, respectively. ICS was avoided in 70%, with no significant difference in mono- versus poly-sensitized patients. ICS-avoidance rates in mono-allergen, pollen-mixture and 2-simultaneous-allergen SLIT were 93.6, 83.3 and 73.7%, respectively. Longer-duration SLIT resulted in significantly more ICS-avoidance (p:0.0001).CONCLUSION: SLIT with mono/multiple-mixed/simultaneous allergens in childhood asthma resulted in retained-avoidance of ICS. Steroid-sparing effect of SLIT in polysensitized children warrants further investigation.
