[Early feeding in infancy and atopic dermatitis - a prospective observational study].

Background: Recommendations for primary prevention of allergic diseases in high-risk children include hypoallergenic infant formulas (HA) if breastfeeding is insufficient. The primary objective of our study was to investigate the atopic dermatitis (AD) preventive effect of breastfeeding and HA-nutrition in the first 2 years of life and to follow the increase in weight.

Patients And Methods: Altogether 174 newborns with a hereditary risk for atopy were enrolled in the study, 121 children were investigated at the age of 2 months, 111 at the age of 4 and 106 at the age of 6 months.

[Cow milk-specific humoral and cellular immune response in infants with high risk of atopy under feeding a whey hydrolysate infant formula].

Background: Hypoallergenic infant formulas (HAF) were developed for atopy prevention in infants with high risk of atopy if these cannot be breastfed. HAF mount an antigen-specific immune response in infants. The aim of the study was to analyse the immune response in infants fed with a new infant formula based on a whey hydrolysate (HAF) and to compare it with that of exclusively breastfed controls.

IgA deficiency in Czech healthy individuals and selected patient groups.

Background: Selective IgA deficiency (IgAD) is the most common immunoglobulin deficiency with a variety of clinical manifestations. The frequency of IgAD differs depending on the ethnic origin and clinical symptoms of investigated persons.

Methods: The prevalence of IgAD (serum IgA level <0.

[IgG subclasses and autoantibodies in adult patients with selective IgA deficiency].

Selective IgA deficiency is the most common primary immunodeficiency disease, but the etiopathogenesis is unknown. In a portion of patients disturbed IgA production is accompanied by various immunological abnormalities. Serological laboratory results of 30 female and 22 male adult patients with selective IgA deficiency were compared with sex- and age-matched healthy controls.
