Preterm Infants on Early Solid Foods and Vitamin D Status in the First Year of Life-A Secondary Outcome Analysis of a Randomized Controlled Trial.

Preterm birth places infants at high risk for mineral and micronutrient deficiencies important for bone health. The aim of this study was to examine whether two timepoints for the introduction of solid foods in preterm infants have an impact on vitamin D status in the first year of life. This is a secondary outcome analysis of a prospective, randomized trial on very low birth weight (VLBW) infants, randomized to an early (10-12th week corrected age) or a late (16-18th week corrected age) complementary-feeding group. Vitamin D status was assessed by blood samples taken at 6 weeks, 6, and 12 months corrected age. In total, 177 infants were randomized (early group: n = 89, late group: n = 88). There was a tendency toward lower levels of serum 25-OH-vitamin D in the early group throughout the first year of life (p = not significant (n.s.)); no differences were detected in the other parameters. At 6 months corrected age, infants of the early group had a significantly higher incidence of vitamin D deficiency. The timepoint of the introduction of solid foods had no impact on the serum 25-OH-vitamin D levels and other parameters important for bone health but showed a tendency toward lower levels in the early-feeding group.

Preterm Infants on Early Solid Foods and Iron Status in the First Year of Life-A Secondary Outcome Analysis of a Randomized Controlled Trial.

Introduction of solid foods and iron status in the first year of life of preterm infants are highly discussed topics. The aim of this study was to examine whether two timepoints of introduction of standardized solid foods in preterm infants have an impact on ferritin and other hematologic parameters important for iron status in the first year of life. This is a secondary outcome analysis of a prospective, randomized intervention trial in very low birth weight (VLBW) infants randomized to an early (10-12th week corrected age) or a late (16-18th week corrected age) complementary feeding group. Iron status was assessed with blood samples taken at 6 weeks, 6 months, and 12 months corrected age. In total, 177 infants were randomized (early group: n = 89, late group: n = 88). Ferritin showed no differences between study groups throughout the first year of life, as did all other parameters associated with iron status. At 12 months corrected age, the incidence of iron deficiency was significantly higher in the early feeding group. There is room for improvement of iron status in VLBW preterm infants, regular blood checks should be introduced, and current recommendations may need to be a reconsidered.

The European Register of Specialists in Clinical Chemistry and Laboratory Medicine: Code of Conduct, Version 2--2008.

In 1997, the European Communities Confederation of Clinical Chemistry and Laboratory Medicine (EC4) set up a Register for European Specialists in Clinical Chemistry and Laboratory Medicine. The operation of the Register is undertaken by a Register Commission (EC4RC). During the last 10 years, more than 2000 specialists in Clinical Chemistry and Laboratory Medicine have joined the Register. In 2007, EC4 merged with the Federation of European Societies of Clinical Chemistry and Laboratory Medicine (FESCC) to form the European Federation of Clinical Chemistry and Laboratory Medicine (EFCC). A Code of Conduct was adopted in 2003 and a revised and updated version, taking account particularly of the guidelines of the Conseil Européen des Professions Libérales (CEPLIS) of which EFCC is a member, is presented in this article. The revised version was approved by the EC4 Register Commission and by the EFCC Executive Board in Paris on 6 November, 2008.

Expression of the high-affinity IgG receptor FcRI (CD64) in patients with inflammatory bowel disease: a new biomarker for gastroenterologic diagnostics.

OBJECTIVES: We sought to determine the quantitative expression of the high-affinity Fc receptor (CD64) on polymorphonuclear neutrophils (PMNs) in inflammatory and functional conditions of the intestine and investigated its correlation with clinical and biological parameters of inflammation. METHODS: The quantitative expression of CD64 was determined by fluorescence-activated cell sorting analysis in patients with active or inactive inflammatory bowel disease (IBD, n=76), infectious enterocolitis, lactose and/or fructose intolerance, and healthy subjects. RESULTS: The quantitative expression of CD64 in patients with active IBD (3,398+/-3,589 molecules per PMN, n=27) was significantly higher than in healthy subjects (607+/-265, n=28, P<0.001) or in patients with lactose/fructose intolerance (531+/-150, n=32, P<0.001). The expression of CD64 correlated significantly with C-reactive protein (CRP, 0.65, P<0.0001), Crohn's disease activity index (CDAI, 0.53, P<0.0001), and colitis activity index (CAI, 0.63, P<0.0001) in patients with IBD. With a cutoff point of 800, CD64 had a sensitivity of 88% and a specificity of 93% in discriminating between lactose/fructose intolerance and active IBD. The quantitative expression of CD64 in patients with infectious enterocolitis (19,190+/-8,920, n=22) was significantly higher than in patients with active IBD (P<0.001). With a cutoff point of 10,000, CD64 showed a sensitivity of 96% and a specificity of 97% in discriminating between infectious enterocolitis and active IBD. CONCLUSIONS: CD64 could serve as a valuable tool to discriminate between IBD, infectious enterocolitis, and functional intestinal disorders.

The European Register for Specialists in Clinical Chemistry and Laboratory Medicine: Code of Conduct.

The European Communities Confederation of Clinical Chemistry and Laboratory Medicine (EC4) opened a Register for European Specialists in Clinical Chemistry and Laboratory Medicine in 1997. The operation of the Register is undertaken by a Register Committee (EC4RC). During the last 6 years more than 1500 specialists in clinical chemistry and laboratory medicine have joined the Register. In this article a Code of Conduct for Registrants which was approved at the EC4 Register Committee meeting in Amsterdam, 8 November 2003 is presented.
