Probiotics prevent IgE-associated allergy until age 5 in cesarean-delivered children but not in total cohort

14.01.2009
According to a recent study from the University and the University Central Hospital of Helsinki, Finland, no allergy-preventive effect is extended to age 5 years by perinatal supplementation with probiotics in babies at risk for developing allergies; protection is conferred only to Cesarean section babies

Childhood allergies have increased significantly in industrialized countries during the past few decades. Researchers theorize that this rising incidence is the result of a lowered exposure to bacteria in early childhood.

This exposure to microbes appears to be essential in jump-starting the immune system to develop healthy pathways that do not result in allergic conditions.

Additionally, it’s been observed that infants who develop allergies have intestinal bacteria that are distinctly different from those of non-allergic infants, suggesting that the type of intestinal microflora is an important factor in forming allergic conditions.

In a study published in the Journal of Allergy and Clinical Immunology (online January 2009) researchers from the University and University Central Hospital of Helsinki conducted a clinical trial of more than 1200 mothers whose infants would be at high risk to develop allergies. During the last month of their pregnancies, the mothers took daily doses of a probiotic mixture or a placebo, and their infants were given the same probiotic mixture plus a prebiotic or a placebo for the first 6 months of their lives. The children were followed for 5 years and evaluated for incidence of allergic diseases.

The authors found that the frequencies of allergic and IgE-associated allergic disease and sensitization were similar in the children who had received probiotic and those who’d gotten placebo. Although there appeared to be a preventive effect at age 2, there was none noted at age 5. Interestingly, in babies born by cesarean section, the researchers found less IgE-associated allergic disease in those who had received the probiotic.

“No allergy-preventive effect is extended to age 5 years by perinatal supplementation with probiotics in babies at risk for developing allergies; protection is conferred only to C-section babies”, says Dr. Mikael Kuitunen from the University Central Hospital of Helsinki. “However, it is possible that stronger and longer stimulation of the infant immune system possibly by varying the strains of bacteria, may result in better allergy-preventive effects.”

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
