Why increasing allergic diseases ?
Reason of Increase of Allergic Disease : Hygiene Hypothesis
• Hygiene hypothesis :
– 1989 by Strachan
– Increase of number of older sibling decrease of allergic disease : due to unhygienic condition and more infection
• Hygiene hypothesis : Life style changes in developed country decrease of infection or improve hygiene condition increase of allergic disease
• Microbial hypothesis :

Relationship between Microbial Exposure and the Probability of Asthma
Ege MJ, et al. NEJM 2011
The risk of asthma decreased significantly with the increase in the number of detectable bands in the PARSIFAL study and with the number of fungal taxa in GABRIELA.
Intestinal Microbiota Hypothesis :
Multiple lifestyle factors may affect intestinal microbiota in early life
→ affect the development of immune tolerance in the intestinal mucosa
→ influence the development of immune system finally
→ may affect the development of immune mediated diseases
Wold AE. The hygiene hypothesis revised: is the rising frequency of allergy due to changes in intestinal flora? Allergy 1998;53:20-5
Microbiome of Various Anatomical Location of the Human Body
Lee YK, et al. Science 2010
• Human Microbiome Project since 2007 over 150 times than human genome • 1000-1150 bacterial species 160 bacteria species/each person
Lifestyle changes have caused a fundamental alteration in association with the microbial world.
How the Microbiome and the Human Genome Contribute to Inflammatory Disease
The community composition of the human microbiome helps to shape the balance between immune regulatory (Treg) and pro-inflammatory (Th17) T cells.

Development and Maintenance of Intestinal Microbiota
Gut microbiota, probiotics, prebiotics and synbiotics – keys to health and longevity (by Vincent Giuliano)
• A key determinant in the development of the human microbiota is likely to be exposure at birth. There are substantial differences between infants according to delivery route. • This component is mainly composed within 1 week after birth, but this may be changed regarding to the host factors and environmental factors within 1 year old. Then the component will be same as adult after 1 year old.

Factors to Influence Intestinal Microbiota in Infant : Delivery Mode
Key determinant in the development of the human microbiota is
likely to be exposure at birth.
Analysis of the microbiota of the newborn infants within 20
minutes of the delivery reveals that although its initial
composition is essentially uniform across different body sites,
there are substantial differences between infants according to
delivery mode.
Whereas the microbiota of vaginally delivered infants is similar to
that of the mother’s vagina or GI tract, the microbiota of infants
delivered by means of cesarean section is similar to that of the
mother’s skin or medical facility.
Mode(Vag Deli) and place(Home Deli) of delivery affect the gastrointestinal microbiota composition(C difficile), which subsequently influences the risk of atopic manifestations. (KOALA, JACI 2011)

Changes in the Composition of the Human Fecal Microbiome After Bacteriotherapy for Recurrent
Clostridium Difficile-Associated Diarrhea: 61 old / F
• Clostridium difficile-associated disease (CDAD) is the major known cause of antibiotic-induced diarrhea and colitis, and the disease is thought to result from persistent disruption of commensal gut microbiota. Bacteriotherapy by way of fecal transplantation can be used to treat recurrent CDAD, which is thought to reestablish the normal colonic microflora. However, limitations of conventional microbiologic techniques have, until recently, precluded testing of this idea.
• In this study, we used terminal-restriction fragment length polymorphism and 16S rRNA gene sequencing approaches
• By 14 days posttransplantation, the fecal bacterial composition of the recipient was highly similar to that of the donor and was dominated by Bacteroides spp. strains and an uncharacterized butyrate producing bacterium. The change in bacterial composition was accompanied by resolution of the patient’s symptoms. The striking similarity of the recipient’s and donor’s intestinal microbiota following after bacteriotherapy suggests that the donor’s bacteria quickly occupied their requisite niches resulting in restoration of both the structure and function of the microbial communities present.
New development of wheeze and BHR are closely related with living of the distance to main road, which suggest that traffic related air pollution may affect the development of asthma.

Conclusion
The prevalence of atopic dermatitis is increasing in Korea.
Environmental exposures in infancy or at pregnancy and genetic
background may be an important independent risk factors in the
development of allergic diseases.
Especially intestinal microbiome status in early life may be critical
to the development of allergic diseases.
Primary prevention of asthma and allergic diseases will only be
possible when the genetic and environmental factors including
intestinal microbiome or the nature of GE interaction have been
identified.
Thus, natural course, risk factors, diagnostic factors, prevention of
childhood asthma and allergic diseases should be identified by
the new hypothesis driven cohort study.
