Caesarean delivery is demonstrated as being a risk factor for IgE-mediated CMA, but it does not increase the risk of AM in these infants. The use of +EH/HGH appears to protect IgE-mediated CMA patients from eventually developing AM.
<b><i>Introduction:</i></b> Cow’s milk allergy (CMA) is a common diagnosis in infants, requiring the exclusion of cow’s milk until tolerance is recovered. In the present study, we aim to determine which factors are associated with the development of tolerance. <b><i>Methods:</i></b> Retrospective, observational study of subjects who underwent the same clinical follow-up methodology. We studied 245 cases of CMA (125 IgE-mediated and 120 non-IgE-mediated). The following variables were analysed: age at diagnosis, gender, type of delivery, type of feeding received, feeding during the first months of life, clinical features, and type of feed received as treatment: casein hydrolysates or casein hydrolysates with <i>Lactobacillus rhamnosus</i> GG (LGG). <b><i>Results:</i></b> Factors associated with earlier tolerance were non-IgE-mediated CMA (HR = 2.92; 95% CI: 2.20–3.88) and patients receiving casein hydrolysate with LGG (HR = 1.79; 95% CI: 1.33–2.42). Later tolerance was associated with caesarean delivery (HR = 0.78; 95% CI: 0.58–1.05) and breastfeeding for a period of at least 3 days (HR = 0.64; 95% CI: 0.44–0.93). The multivariate study shows that the type of formula (HR = 1.61; 95% CI: 1.19–2.18) and the type of CMA (HR = 2.82; 95% CI: 2.12–3.85) have an effect on the recovery time. Casein hydrolysates with LGG reduces the recovery time in IgE-mediated (HR = 1.88; 95% CI: 1.17–3.01) and non-IgE-mediated CMA (HR = 1.46; 95% CI: 0.98–2.17). <b><i>Conclusions:</i></b> Tolerance acquisition is faster in non-IgE-mediated CMA subjects and in those who received casein hydrolysate with LGG.
Background: Cow milk allergy (CMA) is the most common food allergy in breastfed infants. The aim of this study is to verify whether certain perinatal factors may influence the development of CMA immunoglobulin E (IgE)+. Methods: A retrospective, observational study of case and control groups was carried out. Information was collected of patients with CMA IgE+ from our department during the years 1990-2013. Patients of the same age and sex were recruited for the control group. Information on the following variables was collected: sex, age, pregnancy tolerance, duration of pregnancy, type of delivery, isolated doses of formula feeding in hospital (FFH), duration of breastfeeding, and family history of allergy (defined as ≥1 first-degree family member with allergic disease). Statistical analysis was performed using multivariate logistic regression techniques. Results: A total of 211 cases were included in this study. Multivariate analysis showed an influence of duration of breastfeeding, FFH to be a risk factor (OR 4.94; 95% CI 2.68-9.08), especially in caesarean delivery (OR 11.82; 95% CI 2.64-47.50), and prematurity (OR 0.29; 95% CI 0.09-0.92) to be a protective factor. Conclusions: Perinatal factors play a key role in the development of CMA IgE+, with an influence of breastfeeding duration, FFH and caesarean delivery as risk factors and prematurity as a protective factor. While family history had no important role, environmental factors were more decisive.
Con el fin de evaluar la relación entre la práctica de un deporte determinado y la presencia de dermatomicosis se estudiaron, entre octubre y diciembre de 1990, 389 personas, entre 16 y 46 años, vinculadas a la Universidad de Antioquia, divididas en tres grupos de deportistas y uno de controles; los deportistas se subdividieron en calzados, descalzos y húmedos según las circunstancias de su práctica deportiva. En 177 personas (45.5%) se detectó la presencia de alguna dermatomicosis mediante exámenes directos o cultivos. El grupo más afectado fue el de los deportistas calzados cuya frecuencia de estas entidades (54.3%) fue significativamente mayor que la del grupo control (34.7%) (p
