Probiotics added to maternal nutrition affect ınfantile colic symptoms and fecal microbiota profile: a single-blind randomized controlled study
Aysu Yıldız Karaahmet, Gülümser Dolgun, Metehan Özen
Clin Exp Pediatr. 2022;65(11):547-554.   Published online September 23, 2022
Question: Do probiotics added to maternal nutrition affect infantile colic symptoms and intestinal microbiota?
Finding: Infants whose mothers ingested probiotics demonstrated decreased crying frequency and intensity and significantly increased bacterial diversity in the stools. The bacterial variety was substantially affected by the added probiotic product.
Meaning: The addition of probiotics to maternal nutrition in early infancy could play an important role in preventing infantile colic.

Effects of nasopharyngeal microbiota in respiratory infections and allergies
Hyun Mi Kang, Jin Han Kang
Clin Exp Pediatr. 2021;64(11):543-551.   Published online April 15, 2021
· The nasal microbiota varies with age and is shaped by various factors in healthy individuals.
· The pathological condition of the respiratory tract appears to be associated with reduced nasal microbiota biodiversity, while dysbiosis is involved in the pathophysiology of many respiratory diseases, including otitis, sinusitis, allergic diseases, and lower respiratory infections.

Components of human breast milk: from macronutrient to microbiome and microRNA
Su Yeong Kim, Dae Yong Yi
Clin Exp Pediatr. 2020;63(8):301-309.   Published online March 23, 2020
Human breast milk (HBM) is essential for the infant’s growth and development right after birth and is an irreplaceable source of nutrition for early human survival. Various infant formulas have many similarities to HBM in many components, but there is no perfect substitute for HBM. Recently, various breast milk components and their roles have been studied according to the development...

Increasing incidence of inflammatory bowel disease in children and adolescents: significance of environmental factors
Sowon Park, Yunkoo Kang, Hong Koh, Seung Kim
Clin Exp Pediatr. 2020;63(9):337-344.   Published online December 6, 2019
Inflammatory bowel disease (IBD) is a chronic relapsing immune-mediated disease of the intestinal tract. Although its prevalence is reportedly lower in Asia than in Western countries, the rapid increase in the incidence of IBD has drawn attention to its etiology, including genetic susceptibility and environmental factors. Specifically, recent studies concerning dietary treatments and intestinal microbiota suggest that these factors may...

Autoimmunity and intestinal colonization by Candida albicans in patients with type 1 diabetes at the time of the diagnosis
Semra Gürsoy, Tuba Koçkar, Sezen Ugan Atik, Zerrin Önal, Hasan Önal, Erdal Adal
Clin Exp Pediatr. 2018;61(7):217-220.   Published online July 15, 2018

Purpose: Type 1 diabetes mellitus (T1DM) is a chronic and immune-mediated disease, which is characterized by the progressive destruction of pancreatic beta cells. T1DM precipitates in genetically susceptible individuals through environmental factors. In this study, we aimed to evaluate the impact of autoimmunity and intestinal colonization of Candida albicans on the development of T1DM. Methods: Forty-two patients newly diagnosed with T1DM...
Allergy
Clostridium difficile colonization and/or infection during infancy and the risk of childhood allergic diseases
Sun Hwa Lee, Yun Na Gong, Eell Ryoo
Clin Exp Pediatr. 2017;60(5):145-150.   Published online May 31, 2017
Purpose

The gut microbiota can influence several diseases through immune modulation; however, the exact role of microbes such as Clostridium difficileand the relationship between microbiota colonization and allergic diseases are not well known. This study aimed to determine the relationship between C. difficilecolonization and/or infection (CDCI) during infancy and allergic diseases during early childhood.

Methods

Infants 1–12 months of age presenting changes in...

Clinical efficacy and mechanism of probiotics in allergic diseases
Ha-Jung Kim, Hyung Young Kim, So-Yeon Lee, Ju-Hee Seo, Eun Lee, Soo-Jong Hong
Clin Exp Pediatr. 2013;56(9):369-376.   Published online September 30, 2013

A complex interplay between genetic and environmental factors partially contributes to the development of allergic diseases by affecting development during prenatal and early life. To explain the dramatic increase in the prevalence of allergic diseases, the hygiene hypothesis proposed that early exposure to infection prevented allergic diseases. The hygiene hypothesis has changed to the microbial hypothesis, in which exposure to...
