The usefulness of soluble transferrin receptor (sTfR) in differentiating anemia occurring in young children
We evaluated the usefulness of soluble transferrin receptor (sTfR) and of the sTfR/log ferritin index(sTfR/logF) in the differentiation of anemia in young children. 96 children, aged 6–36 months, were examined.From these, four groups were distinguished: 1 — (IDA): 33 children with anemia due to iron deficiency; 2 —(IA): 19 children with infectious anemia without iron deficiency; 3 — (IA + ID): 16 children with infectiousanemia and iron deficiency; and 4 — a comparator group (CG): 28 healthy children without iron deficiency. Thesoluble transferrin receptor, hematological indices and iron balance were evaluated and the sTfR/logF wascalculated for each examined child. It was proved that the mean values of sTfR and sTfR/logF were substantiallyhigher in children with anemia due to iron deficiency, and in those with infectious anemia and iron deficiency,vs. those with infectious anemia or in healthy children. This suggests that both sTfR and the sTfR/logF are goodindicators of iron deficiency and could be useful in the differential diagnostics of anemia, especially in youngchildren.We evaluated the usefulness of soluble transferrin receptor (sTfR) and of the sTfR/log ferritin index(sTfR/logF) in the differentiation of anemia in young children. 96 children, aged 6–36 months, were examined.From these, four groups were distinguished: 1 — (IDA): 33 children with anemia due to iron deficiency; 2 —(IA): 19 children with infectious anemia without iron deficiency; 3 — (IA + ID): 16 children with infectiousanemia and iron deficiency; and 4 — a comparator group (CG): 28 healthy children without iron deficiency.

Pre- and postnatal exposure of children to tobacco smoke during the first four years of life-observations of the authors
[b]Introduction[/b]. Environmental exposure to tobacco smoke is a significant threat for human health, where the higher is its degree, the more immature the human organism is. Therefore, the exposure to Tobacco smoke in foetal life exerts unfavourable effects on developing foetus and may cause early and distant results in children.
[b]Material and methods.[/b] The study comprised 318 children in their first four years of life, treated for various medical conditions. The examined children were divided into two groups, Group 1 – children exposed to Tobacco smoke – and Group 2 – a control group with children from non-smoking families. History data were obtained on the basis of a specially designed questionnaire, used by the doctor in an individual conversation with parent. In each third child from the group 1 cotinine concentration in urine was assayed by the method of high performance liquid chromatography-UV-VIS and the cotinine/creatinine ratio was calculated.
[b]Results of stud[/b][b]y[/b]. Results demonstrated environmental exposure to tobacco smoke in 173 children (Group 1). Out of them 31.2% were the children whose mothers had smoked also during pregnancy (Subgroup A). The other 119 children from Group 1 were accounted to Subgroup B, i.e., children, where other household members had been smoking cigarettes. A comparative group comprised 143 children from non-smoking families. The results demonstrated then that 17% of all the examined children were those, exposed to tobacco smoke effects already in their foetal life, predisposing them to prematurity and low birth weight. Moreover, it was observed that the young age and lower education level of their parents, together with worse housing conditions, may suggest a predisposing character and role of the mentioned factors

The allergic sensitization in infants with atopic eczema from different countries
No study has compared allergic sensitization patterns in infants with atopic eczema from different countries. The aim of this study was to investigate the patterns of allergic sensitization in a cohort of infants with atopic eczema participating in a multicentre, international study
Confirmation of the association between high levels of immunoglobulin E food sensitization and eczema in infancy: an international study
Background Studies of Australian infants have reported that more than 80% of those with moderate atopic eczema (AE) have high levels of IgE food sensitization (IgE-FS) that are commonly associated with IgE food allergy.
Objectives To explore the relationship between high levels of IgE-FS and AE in a large cohort of young children with eczema participating in a multi-centre, international study.
Methods Two thousand one hundred and eighty-four subjects (mean age 17.6 months, range 11.8-25.4; 1246 males) with active eczema from atopic families from 94 centres in 12 countries were studied. Clinical history, Scoring Atopic Dermatitis index as a measure of eczema severity and CAP-FEIA measurements for total IgE and IgE antibody levels to cow milk, egg and peanut were entered into a database. If CAP-FEIA levels exceeded previously reported age-specific cut-off levels for 95% positive predictive values (PPVs) for food allergy, subjects were defined as having high-risk IgE-FS (HR-IgE-FS).
Results Serum was available from 2048 patients; 55.5% were atopic. The frequency of HR-IgE-FS to milk, egg and/or peanut was the greatest in patients whose eczema developed in the first 3 months of life and the least in those whose eczema developed after 12 months (P < 0.0001). In a regression analysis to allow for potential confounding factors, children with HR-IgE-FS had the most severe eczema and the youngest age of onset (P < 0.001); 64% of infants with severe eczema of onset-age <3 months had HR-IgE-FS.
Conclusion Early-onset severe eczema in infancy was associated with HR-IgE-FS. Clinical implications Food allergies should be routinely assessed in infants with moderate or severe eczema. Capsule summary In eczematous infants, the earlier the age of onset, and the greater the severity of eczema, the greater the frequency of associated high levels of IgE-FS
