Differences in Developing Intestinal Microbiota between Allergic and Non-Allergic Infants: A Pilot Study in Japan

Abstract: The bacterial compositions of feces were monitored in the first 2 months for 15 infants born in Japan, including eight subjects who developed allergy by the age of 2 years. Primer sets targeting six predominant bacterial groups in the infant intestine, Bacteroidaceae, Enterobacteriaceae, bifidobacteria, enterococci, lactobacilli, and the Clostridium perfringens group, were used for real-time PCR to quantitate each population in the feces. The population of Bacteroidaceae was significantly higher in the allergi… Show more

“…As E. coli was only associated with eczema and C. difficile was associated with all atopic outcomes, the underlying mechanisms may be different. Colonization with clostridia, including C. difficile, was associated with allergy development up to age 2 years in several studies (Kalliomaki et al, 2001a;Bjorksten et al, 2001;Penders et al, 2007) but not in others (Adlerberth et al, 2007;Sjogren et al, 2009;Songjinda et al, 2007). Fecal colonization at age 3 weeks with Clostridium coccoides subcluster XIVa species has been described as an early indicator of possible asthma later in life Vael et al, 2011).…”

“…Indeed, it seems unlikely that all members of this genus exert the same effects on the human immune system (Penders et al, 2007). Children not developing allergy before age 2 years have been shown to be more frequently colonized with bifidobacteria than children developing allergy (Bjorksten et al, 2001), but this decreased prevalence of Bifidobacterium in children suffering allergies was not confirmed in all studies (Songjinda et al, 2007;Penders et al, 2006a;Adlerberth et al, 2007). Differences in patterns of colonization by bifidobacteria species have also been observed but no clear consensus exists.…”

“…Результаты исследования преморбидного состояния кишечной микрофлоры у детей, впоследствии развивших симптомы пищевой аллергии, показали, что дисбиоз кишечника и нарушение пищевой толерантности у ребенка являются отражением нарушения одних и тех же процессов в иммунной системе и, соответственно, разви-ваются параллельно [56,57]. Дисбиоз кишечника, под кото-рым в настоящее время понимают нарушение соотношения защитной флоры и патобионтов (условно-патогенных бак-терий), не являясь нозологической формой, тем не менее может вносить свой вклад в клиническую картину забо-леваний, связанных с пищевой аллергией.…”

“…Именно поэтому отмечается быстрая регрессия этих нарушений на фоне эффективной терапии основного заболевания. У детей со склонностью к атопии дефицит бифидобактерий и лактобацилл, как указано выше, носит преморбидный характер [56,57]; он может быть связан с особенностями иммунного ответа данной категории детей, нарушениями процессов пер-вичной колонизации и поэтому имеет стойкий характер, сохраняется более длительно. Более того, сохранению дефицита бифидобактерий отчасти может способствовать назначение безмолочной диеты при аллергии к белку коровьего молока, когда из питания полностью исключа-ются кисломолочные продукты.…”

“…The total DNA in the suspension was mostly degraded as was demonstrated by real-time PCR amplification using Lactobacillus (LactoR'F/LBFR, (Songjinda et al, 2007) ) or Bifidobacterium (Bif-F/Bif-R, (Rinttila et al, 2004). The two-times autoclaved suspension was spiked with either of the two strains isolated from the product, and after that DNA isolated from the spiked suspension was used for the generation of standard curves.…”
