Atopic diseases constitute a common health problem. For infants at hereditary risk, prophylaxis of atopy has been sought in elimination diets and other preventive measures. We followed up healthy infants during their first year, and then at ages 1, 3, 5, 10, and 17 years to determine the effect on atopic disease of breastfeeding. Of the initial 236 infants,(More)
BACKGROUND Relationships between early deficits of lung function, infant airway pathology and outcome in symptomatic infants are unclear. A study was undertaken to determine the associations between early lung function, airway histology and inflammation in symptomatic infants with the continuance of respiratory symptoms, lung function and subsequent use of(More)
Monogenic causes of autoimmunity provide key insights into the complex regulation of the immune system. We report a new monogenic cause of autoimmunity resulting from de novo germline activating STAT3 mutations in five individuals with a spectrum of early-onset autoimmune disease, including type 1 diabetes. These findings emphasize the critical role of(More)
BACKGROUND Peak bone mass, attained by early adulthood, is influenced by genetic and life-style factors. Early infant feeding and duration of breastfeeding in particular, associate with several health-related parameters in childhood. The aim of this study was to examine whether the effects of early infant feeding extend to peak bone mass and other bone(More)
54 babies who had been solely breast-fed for more than 6 months, 77 babies who had been breast-fed for 2--6 months, and 105 babies who had been weaned to cow's-milk-based formulas at less than 2 months were followed for the first 3 years of life. All the babies had the same pattern of solid food intake until 1 year of age. Compared with formula feeding,(More)
In a study of fish and citrus allergy these foods were strictly avoided in 177 children up to 1 year of age, whereas 152 children had started taking fish before age 6 months and 145 children had started taking citrus fruits beofre 3 months. Both fish and citrus allergy, defined by a positive challenge, were found at age 3 years in a similar frequency (about(More)
OBJECTIVE Both osteoporosis and cardiovascular disease (CVD) are diseases that comprise a growing medical and economic burden in ageing populations. They share many risk factors, including ageing, low physical activity, and possibly overweight. We aimed to study associations between individual risk factors for CVD and bone mineral density (BMD) and turnover(More)
BACKGROUND Few data are available about the inflammatory cytokine profile of bronchoalveolar lavage (BAL) from young children with frequent wheeze. The first aim was to investigate the BAL cellular and cytokine profiles in infants with recurrent lower respiratory symptoms in whom bronchoscopy was indicated for clinical symptom evaluation. The second aim was(More)
