Effect of short-term partial enteral nutrition on the treatment of younger patients with severe Crohn's disease
BACKGROUND/AIMS: To analyze the effect of short-term supportive temporary partial enteral nutrition therapy for treating severe pediatric Crohn's disease (CD).
METHODS: We conducted a prospective, open-label study in pediatric patients with CD (n=78) from January 2007 to December 2011. The CD patients were divided into three groups according to disease severity (mild, moderate, and severe). Seventeen patients with severe CD received short-term partial enteral nutrition (SPEN) in addition to their general diet for 4 weeks after the induction of remission with medical treatment. This SPEN group was further divided into two groups by age (<13 years, โฅ13 years). Nutritional parameters and Pediatric Crohn's Disease Activity Index scores were analyzed at the initial enrollment and following 1 year of treatment for all groups.
RESULTS: Nutritional status improved substantially after 1 year of treatment in the severe CD group. Nutritional status in the SPEN group improved considerably more than that in the non-SPEN group. Additionally, the <13-year-old group demonstrated better nutritional status improvement than the โฅ13-year-old group.
CONCLUSIONS: SPEN may be effective in pediatric patients with severe CD for improving nutritional status and moderating disease severity.ope
Micronutrients Are Not Deficient in Children with Nonorganic Failure to Thrive
Purpose:
Inadequate calorie intake is one of the most important causes of nonorganic failure to thrive (NOFTT) and is thought to lead to multiple micronutrient deficiencies. However, there have been few studies on NOFTT and micronutrients. The aim of this study was to evaluate the micronutrient status of children with NOFTT.
Methods:
We conducted a retrospective cohort study in 161 children (106 with NOFTT and 55 health controls) at a single institution. Data on weight for age, height for age, body mass index, and biochemical parameters, indicating the children's nutritional and micronutrient status were reviewed via electronic medical records, and the two groups were compared.
Results:
Except inorganic phosphate levels, no statistically significant differences were seen in the laboratory findings indicating the children's nutritional and micronutrient status; notably, the inorganic phosphate levels were within the normal range in both groups. We then compared the severe NOFTT (weight for age below the first percentile) and control groups; however, no statistically significant differences were seen for any of the measured parameters.
Conclusion:
Most children with NOFTT in this study had normal micronutrient levels and other laboratory findings. Therefore, element deficiencies should not be considered a natural consequence of NOFTT or in healthy children. Close monitoring and additional evaluations are needed.ope
Correlation Between The Occurrence Of Acute Gastroenteritis In Children And Regional Temperature At A Tertiary Hospital Emergency Department In Korea
Purpose
Several studies have investigated the association between acute gastroenteritis (AGE) and regional temperatures. We aimed to investigate the correlation between the occurrence of AGE and regional temperature in Korean children.
Methods
We reviewed the clinical characteristics of children aged 18 years or younger with AGE, defined according to the International Statistical Classification of Diseases, 10th Revision codes, who visited a Korean tertiary hospital emergency department (ED) between 2006 and 2016, and compared the children who were discharged from the ED and those who were hospitalized. Data on temperature in Seoul, Korea during the period were obtained from the Korea Meteorological Administration. Subsequently, we assessed correlations between the monthly mean numbers of the children with AGE and monthly mean temperature using Pearsonโs correlation analysis.
Results
A total of 31,931 children with AGE visited the ED. Vomiting was the most common manifestation (62.0%). Fever, chills, cough, and sputum were more frequent in the hospitalized children (P < 0.05). Hospitalization rate was highest (2.7%) and monthly mean temperature was lowest (-2.4ใC) in January. We observed negative correlations between the monthly mean numbers of the children with AGE and the monthly mean temperature (for ED visit, r = -0.845; for hospitalization, r = -0.923).
Conclusion
Children with AGE tend to visit the ED, and undergo hospitalization during the cold weather. This finding could help the guardians to expect the occurrence of AGE, and physicians to facilitate the allocation of resources for emergency medicine in winter.ope
Normal serum alanine aminotransferase and non-alcoholic fatty liver disease among Korean adolescents: a cross-sectional study using data from KNHANES 2010-2015
BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is complicated disease and increasing worldwide. Previously, many studies of NALFD prevalences have used alanine aminotransferase (ALT) of > 40 U/L to define NAFLD, although that is too high to be reliable among adolescents. This study aimed to define the upper normal limit of ALT among Korean adolescents, and use it to estimate the prevalence of NAFLD, based on data from the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: Data were obtained from 1785 healthy adolescents (916 boys and 869 girls, 10-18 years old) who participated in the KNHANES during 2010-2015. The International Diabetes Federation metabolic syndrome criteria for adolescents were used to exclude participants with metabolic syndrome components. Furthermore, participants who previously had diseases related to low HDL levels, high TG levels, diabetes, or very low/high body mass index and hepatitis B were excluded. The 95th percentiles level of ALT from healthy participants were evaluated. The definition of NAFLD was overweight status (>/=85th percentile of body mass index) plus elevated ALT levels (95th percentile). RESULTS: The upper normal ALT were 24.1 U/L for boys and 17.7 U/L for girls. Based on these values, the estimated prevalences of NAFLD in 2015 were 8.9% among adolescents. CONCLUSION: Defining the upper normal limit of ALT can be adjusted for each sex and ethnics in the general population. ALT laboratory thresholds used for children should be re-examined. The physicians should be aware not to underdiagnose NAFLD patient even ALT level is < 40 U/L.ope
Life-threatening lower gastrointestinal hemorrhage in pediatric Crohn's disease
In Crohn's disease, mild gastrointestinal bleeding often occurs; however massive gastrointestinal hemorrhage, which can have a dramatic effect on a patient's vital sign, is rare. This could result in potentially life-threatening complications, which can lead to death. Massive hemorrhagic Crohn's disease is not well known and for this reason, they are a diagnostic and therapeutic challenge. Various diagnostic and therapeutic methods are currently being developed and used. The surgical method is often used only as a last measure since this approach has the risk of serious complications that may endanger patients. However, if massive bleeding continues even after all therapeutic methods are used, the surgical method must be implemented. In this case, all therapeutic methods were found to be ineffective; therefore, surgery was used as a last option. Ultimately, the surgical method was found to be successfully used to treat life-threatening hemorrhagic Crohn's disease.ope
Estimated Prevalence of Adolescents with Nonalcoholic Fatty Liver Disease in Korea
BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) has become prevalent worldwide in the last decade. However, the recent prevalence of NAFLD in adolescents has not yet been investigated in Korea. METHODS: Data were obtained from 1,416 participants aged 10-18 years from the Korea National Health and Nutrition Examination Survey conducted in 2010 and 2015. Systolic blood pressure (SBP), diastolic blood pressure (DBP), height, weight, waist circumference (WC), body mass index (BMI), fasting glucose, total cholesterol, high-density lipoprotein (HDL), aspartate aminotransferase (AST), alanine aminotransferase (ALT) level, waist-to-height ratio (WHtR), and pediatric NAFLD fibrosis index (PNFI) were analyzed. RESULTS: SBP, weight, WC, BMI, WHtR, and total cholesterol level were significantly higher in 2015 than in 2010. Prevalence of NAFLD (BMI >/= 85th percentile plus ALT > 30 U/L for boys and ALT > 19 U/L for girls) were 4.7% in 2010 and 5.9% in 2015 (P = 0.360). Using various cutoffs for the ALT level (> 40, > 30, > 25.8 U/L for boys and >22.1 U/L for girls) NAFLD prevalence rates were 3.0%, 4.1%, and 5.5% in 2010; 2.9%, 5.0%, and 7.1% in 2015, respectively (P = 0.899, 0.469, and 0.289). Boys had a higher SBP, DBP, height, weight, WC, BMI, WHtR, fasting glucose, total cholesterol, ALT, and lower HDL level than girls. The probability of liver fibrosis using the PNFI varies between 21.3% and 24.5% among NAFLD participants (P < 0.001). CONCLUSION: The Korean society needs to quickly control the increasing prevalence of NAFLD in adolescents and reduce its complications.ope

Purpose: The efficacy of exclusive enteral nutrition (EEN) with a polymeric diet has not been confirmed in Korean pediatric patients with Crohn's disease (CD). This study aimed to compare the effectiveness of EEN with a specific polymeric diet (Encoverยฎ) and corticosteroids (CSs) for the induction of remission in Korean pediatric CD patients.
Methods: We retrospectively compared data from 51 pediatric CD patients who underwent induction therapy with EEN (n=19) or CSs (n=32) at Severance Children's Hospital or Incheon St. Mary's Hospital in Korea. The primary endpoint of this study was the rate of clinical remission, defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score <10, after 8 weeks of induction treatment. Clinical, laboratory, and growth data at post-induction as well as their changes from baseline were also compared between groups.
Results: After 8 weeks of induction therapy, clinical remission rates were 78.9% (15/19) and 65.6% (21/32) in the EEN and CS groups, respectively (p=0.313). No significant differences in PCDAI scores, laboratory variables, and growth parameters were noted between the two groups at post-induction. However, significant changes in albumin levels at post-induction were observed in the EEN group compared to the CS group (p=0.038).
Conclusion: Our results suggest that the effectiveness of EEN with a polymeric diet and CSs for induction therapy did not differ in Korean pediatric CD patients. EEN with a polymeric diet is a good first-line treatment option for the induction of remission in these patients.ope
Association of Vitamin D with Inflammatory Bowel Disease Activity in Pediatric Patients
BACKGROUND: It has been known that vitamin D level (serum 25[OH]D) has correlation with inflammatory bowel disease (IBD). The purpose of this study is to investigate changes of serum 25[OH]D in pediatric IBD patients according to the disease activity.
METHODS: A total of 96 children and adolescent with IBD were enrolled in this retrospective study. Serologic inflammatory markers and clinical disease activity scores of the patients were collected, and their correlations with serum 25[OH]D were analyzed. Seasonal variations of serum 25[OH]D were also investigated both in active disease state and remission state.
RESULTS: Of the 96 patients, 41 (43%) were women and patients with a vitamin D deficiency (< 20 ng/mL) at diagnosis were 77 (80.2%). There was no significant difference between Crohn's disease and ulcerative colitis for serum 25[OH]D. Serum 25[OH]D was higher in remission group than in active disease group (12.4 [8.8-29] ng/mL vs. 17.9 [12.3-34.4] ng/mL; P < 0.001) and the difference was more significant than other micronutrients. There was no significant difference in serum 25[OH]D concentration between patients with ileal involvement and patients without ileal involvement. There were seasonal variations in the active phase, but there was no significant difference by season in the remission phase.
CONCLUSION: Serum 25[OH]D is inversely correlated with disease activity in IBD. Monitoring and supplementation is required especially for active disease status and in winter and spring season.ope
The efficacy of aspartate aminotransferase-to-platelet ratio index for assessing hepatic fibrosis in childhood nonalcoholic steatohepatitis for medical practice
PURPOSE: Childhood obesity is associated with nonalcoholic fatty liver disease (NAFLD), and it has become one of the most common causes of childhood chronic liver diseases which significant as a cause of liver related mortality and morbidity in children in the United States. The development of simpler and easier clinical indices for medical practice is needed to identify advanced hepatic fibrosis in childhood NAFLD instead of invasive method like liver biopsy. FibroScan and aspartate aminotransferase (AST)-to-platelet ratio index (APRI) have been proposed as a simple and noninvasive predictor to evaluate hepatic fibrosis in several liver diseases. APRI could be a good alternative to detect pathologic change in childhood NAFLD. The purpose of this study is to validate the efficacy of APRI for assessing hepatic fibrosis in childhood NAFLD based on FibroScan.
METHODS: This study included 23 children with NAFLD who underwent FibroScan. Clinical, laboratory and radiological evaluation including APRI was performed. To confirm the result of this study, 6 patients received liver biopsy.
RESULTS: Factors associated with hepatic fibrosis (stiffness measurement >5.9 kPa Fibroscan) were triglyceride, AST, alanine aminotransferase, platelet count, APRI and collagen IV. In multivariate analysis, APRI were correlated with hepatic fibrosis (>5.9 kPa). In receiver operating characteristics curve, APRI of meaningful fibrosis (cutoff value, 0.4669; area under the receiver operating characteristics, 0.875) presented sensitivity of 94%, specificity of 66%, positive predictive value of 94%, and negative predictive value of 64%.
CONCLUSION: APRI might be a noninvasive, simple, and readily available method for medical practice to predict hepatic fibrosis of childhood NAFLD.ope
The clinical significance of serum ferritin in pediatric non-alcoholic Fatty liver disease
PURPOSE: Non-alcoholic fatty liver disease (NAFLD) in children has become an important public health issue because of its high prevalence and severity. Several noninvasive methods for estimating NAFLD are under investigation. We aimed to evaluate the usefulness of serum ferritin as a biomarker of severity of pediatric NAFLD patients.
METHODS: A total of 64 NAFLD patient were enrolled from Severance Children's Hospital from March 2010 to February 2013. Serum ferritin levels, liver related laboratory tests, liver magnetic resonance imaging (MRI) (2-dimensional [2D] proton density-fat fraction) and NAFLD severity markers were compared between obese group and overweight group. Correlation analyses were performed between serum ferritin and laboratory values including NAFLD severity markers.
RESULTS: In obese group, serum ferritin, alanine aminotransferase (ALT), total bilirubin, international normalized ratio (INR), MRI 2D proton density-fat fraction, aspartate aminotransferase (AST) to platelet ratio index (APRI) and fibrosis-4 (FIB-4) (an index score calculated from platelet count, ALT, AST and age) were significantly higher than those of overweight group. NAFLD severity markers, APRI and FIB-4, and liver specific important laboratory values, AST, ALT, INR, cholesterol, triglyceride and low density lipoprotein show significant correlation with serum ferritin in NAFLD patients.
CONCLUSION: Serum ferritin concentrations could be a candidate of useful severity marker in the pediatric NAFLD patients.ope
