Abstract

PURPOSE: The purpose of our study was to investigate the risk factors in developing persistent wheezing in infants with recurrent wheezing.
METHODS
Two hundred thirty two infants with recurrent wheezing under two years old visited to Pediatric Allergy and Respiratory Center in Soonchunhyang University Hospital from August 1998 to May 2002 were enrolled and investigated until May 2006, retrospectively. The patients were divided into two groups; persistent wheezer group (PW) who had recurrent wheezing until six years old and transient wheezer group (TW) who didn't have wheezing after three years old. The patients' demographics and laboratory data such as serum total IgE, specific IgE (Dp, Df, dog hair, egg white, milk, soy) and peripheral blood eosinophil count at the first visit were analysed to investigate the risk factors for developing persistent wheezing.
RESULTS
PW was 115 (49.5%) and TW was 117 (50.5%) out of 232 infants with recurrent wheezing. In comparison analysis between PW and TW, there were no significant differences in age (months), serum total IgE, peripheral blood eosinophil (P=0.319), birth weight, and gestational age. However, increased serum total IgE (OR 1.72; 95% CI 1.01-2.90), sensitization to Dp (3.6, 1.14-11.39) and egg white (2.96, 1.49-5.89), family history of allergic diseases (2.35, 1.33-4.13), personal history of atopic dermatitis (2.08, 1.11-3.89), and not having older siblings (2.93, 1.64-5.24) had statistic significance. Among these results, not having older sibling (adjusted OR 2.74, 1.46-5.13) and having family history of allergic diseases (adjusted OR 2.69, 1.39-5.18) had strong significance by regnession a nalysis.
CONCLUSION
Early intervention of infants with high risk factors for developing persistent wheezing may improve their outcome. Therefore early intervention of infants with high risk factors will be necessary for preventing develop childhood asthma.
