摘要
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%26apos; nares and skin (cubital fossa) and swabs of the mothers%26apos; nares were collected. for univariate analysis, x2 (chi-square) and fischer exact%26apos;s test were used. results: among breastfed children, s. aureus was isolated from 8 (25.8%) infants%26apos; nares swabs and from 4 (12.9%) skin swabs. among not breastfed children, s. aureus was isolated from 10 (20.8%) infants%26apos; 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
