CHEMELLO, Raissa Massaia Londero et al. Breastfeeding and mucosal and cutaneous colonization by Staphylococcus aureus in atopic children. An. Bras. Dermatol. [online]. 2011, vol.86, n.3, pp.435-439. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962011000300002.
BACKGROUND: Studies on the effects of breastfeeding on the development of Atopic Dermatitis (AD) have shown controversial results. The importance of this condition deserves further studies; in particular, it remains unclear whether colonization of atopic patients by Staphylococcus aureus (S. aureus) through breastfeeding is relevant to the development of AD. OBJECTIVE: To examine the potential relation between breastfeeding and colonization by S. aureus in atopic patients. METHOD: Transversal study of atopic patients, aged from 4 to 24 months, both genders, receiving outpatient care and 72 mothers. Data on infant breastfeeding practices and on clinical-epidemiological profile were registered. Swabs of the infants' nares and skin (cubital fossa) and swabs of the mothers' nares were collected. For univariate analysis, X2 (chi-square) and Fischer Exact's test were used. RESULTS: Among breastfed children, S. aureus was isolated from 8 (25.8%) infants' nares swabs and from 4 (12.9%) skin swabs. Among not breastfed children, S. aureus was isolated from 10 (20.8%) infants' nares swabs and from 11 (22.9%) skin swabs. Sixteen mothers (22.2%) had S. aureus isolated from their nares swabs. There was no significant association between breastfeeding and S. aureus colonization (child skin and/or nares). However, there was a degree of concordance for S. aureus carriage among mothers and infants. Among 72 pairs, 56 (77.8%) were concordant. CONCLUSION: Breastfeeding was not associated with S. aureus muco-cutaneous colonization in atopic infants
