Abstract
BACKGROUND An increasing incidence of pediatric-onset inflammatory bowel disease (PIBD) has been reported in many countries. However, the global burden and distribution of this disease remain less understood. We aimed to examine the global epidemiology and trends of PIBD from 1990 to 2019. METHODS Data from the 2019 Global Burden of Disease Study, covering 204 countries, were analyzed. We assessed key measures like incidence, prevalence, mortality, and disability-adjusted life years (DALYs) using linear regression to calculate annual percentage changes and assess trends. RESULTS Between 1990 and 2019, the PIBD incidence rate increased and the DALY rate and mortality rate declined. The incidence rate was notably elevated in the high Socio-demographic Index (SDI) quintile, reaching 6.3 per 100 000 person-years, corresponding to 13 914 new cases in 2019. Incidence and prevalence of PIBD positively correlated with the SDI, while higher death and DALY burdens were observed in lower-SDI countries. In 2019, the top 5 countries with the highest PIBD incidence rates were Canada (19.9 per 100 000 population), Denmark (12.4 per 100 000 population), Hungary (8.5 per 100 000 population), Austria (8.1 per 100 000 population), and the United States (7.4 per 100 000 population). Several countries experienced significant increases in incidence rates from 1990 to 2019, led by Taiwan (annual percent change 4.2%), followed by China (2.8%), Japan (2.1%), Australia (1.8%), and Hungary (1.6%). DISCUSSION PIBD incidence has significantly increased since 1990. High-SDI countries face higher incidence, while lower-SDI countries experience higher mortality and DALY burdens. The study underscores the need for ongoing monitoring and research to address this emerging public health issue.

Abstract
BACKGROUND The global incidence of paediatric inflammatory bowel disease (IBD) is increasing. Much of the evidence attesting to this has arisen from North America and Europe. There is a relative paucity of information on the epidemiology of paediatric IBD in the Southern Hemisphere. The present study aimed to document the prospectively collected incidence of paediatric IBD in New Zealand in 2015. METHODS All patients younger than 16 years of age and diagnosed with IBD in New Zealand between 1 January 2015 and 31 December 2015 were identified. Demographic and disease phenotypic details were collected and entered into a secure database. Age-specific population data for New Zealand were obtained and national incidence rates for IBD and its subtypes were calculated. RESULTS The prospectively calculated incidence of paediatric IBD, Crohn disease, ulcerative colitis (UC), and IBD unclassified in New Zealand in 2015 were 5.2 (95% confidence interval 3.9-6.8), 3.5 (2.4-4.8), 1.0 (0.5-1.8), and 0.7 (0.3-1.4) per 100,000 children, respectively. CONCLUSIONS Incidence rates of paediatric IBD in New Zealand are comparable to the highest rates published in the literature from Western Europe and North America. Ongoing prospective ascertainment of the incidence of paediatric IBD is required to better understand the environmental factors, which are accounting for this increase in disease burden.

Abstract
BACKGROUND The incidence of paediatric inflammatory bowel disease (IBD) around the world is increasing. Canterbury, New Zealand, has one of the highest Crohn disease (CD) incidence rates published. The present study aimed to document the incidence of paediatric IBD in Canterbury between 1996 and 2015. METHODS All patients diagnosed with IBD in Canterbury, while younger than 16 years, between January 1, 1996 and December 31, 2015 were identified. Demographic and disease phenotypic details were collected and entered into a secure database. Age-specific population data for Canterbury were obtained and annual incidence rates were then calculated. RESULTS The mean annual incidence rate over the 20-year period was 7.18/100,000 (95% confidence interval 5.55-8.81) children. There was a 4-fold increase in the incidence of paediatric IBD in Canterbury between 1996 and 2015. The ratio of CD to ulcerative colitis (UC) diagnosed was 8.4:1. Disease phenotype of CD and UC, based on the Paris classification, were comparable with other studies. CONCLUSIONS The incidence of paediatric IBD in Canterbury has increased dramatically during the last 2 decades. Some of the observed incidence rates are among the highest documented anywhere in the world. The preponderance of CD over UC in the present study is the highest published.

Abstract
BACKGROUND The incidence of pediatric inflammatory bowel disease (IBD) around the world is increasing. However, there is a scarcity of data on the epidemiology of pediatric IBD in the Southern Hemisphere. This study aimed to document the point prevalence of pediatric IBD in New Zealand on June 30, 2015. METHODS All patients in New Zealand, under 16 years of age, with a diagnosis of IBD on June 30, 2015 were identified. Demographic and disease phenotypic details were collected and entered into a secure database. Age-specific population data for New Zealand were obtained and national and regional prevalence rates were calculated. RESULTS The point prevalence of pediatric IBD, Crohn's disease, ulcerative colitis, and inflammatory bowel disease unclassified in New Zealand on June 30, 2015 was (95% confidence intervals) 21.7 (18.9-24.8), 16.5 (14.0-19.2), 3.3 (2.2-4.6), and 1.9 (1.2-3.0) per 100,000 children, respectively. There was a striking disparity between the prevalence rates in the North and South Islands. CONCLUSIONS The point prevalence of pediatric IBD in New Zealand represents the first-ever national, population-based prevalence rates of pediatric IBD published. Results from the Paediatric IBD in New Zealand (PINZ) study are also the first to show markedly higher prevalence rates of IBD in the southern part of a country compared with its northern counterpart. Ongoing prospective ascertainment of the incidence of pediatric IBD is required.

Abstract
OBJECTIVE Patients with ADHD have been suggested to have increased risks of allergic diseases but without consistent results, and limited studies about the association between ADHD and autoimmune diseases were noted in the literature. METHOD Utilizing the Taiwan National Health Insurance Research Database, ADHD patients were identified and compared with age- and gender-matched controls (1:4). RESULTS In all, 8,201 participants were identified as having ADHD, and an increased prevalence of allergic diseases, including asthma (odds ratio [OR] = 1.53), allergic rhinitis (OR = 1.59), atopic dermatitis (OR = 1.53), and urticaria (OR = 1.39), compared with the control group. Although the comorbidity of autoimmune diseases with ADHD was low, ADHD patients had a significantly greater prevalence of ankylosing spondylitis (OR = 2.78), ulcerative colitis (OR = 2.31), and autoimmune thyroid disease (OR = 2.53) than the controls. CONCLUSION Our results supported the association between ADHD and allergic/autoimmune diseases. The further studies will be required to clarify the underlying mechanisms.

Abstract
Matrix metalloproteinases (MMPs) are known to be upregulated in inflammatory bowel disease (IBD) and other inflammatory conditions, but while their involvement is clear, their role in many settings has yet to be determined. Studies of the involvement of MMPs in IBD since 2006 have revealed an array of immune and stromal cells which release the proteases in response to inflammatory cytokines and growth factors. Through digestion of the extracellular matrix and cleavage of bioactive proteins, a huge diversity of roles have been revealed for the MMPs in IBD, where they have been shown to regulate epithelial barrier function, immune response, angiogenesis, fibrosis, and wound healing. For this reason, MMPs have been recognised as potential biomarkers for disease activity in IBD and inhibition remains a huge area of interest. This review describes new roles of MMPs in the pathophysiology of IBD and suggests future directions for the development of treatment strategies in this condition.

Abstract
BACKGROUND Early-onset (EO) pediatric inflammatory bowel diseases (IBD) seem to be more extensive than those with a later onset. To test this hypothesis, we examined the phenotype and disease course of patients with IBD diagnosis at 0 to 5 years, compared with the ranges 6 to 11 and 12 to 18 years. METHODS Anatomic locations and behaviors were assessed according to Paris classification in 506 consecutive patients: 224 Crohn's disease, 245 ulcerative colitis, and 37 IBD-unclassified. RESULTS Eleven percent of patients were in the range 0 to 5 years, 39% in 6 to 11 years, and 50% in 12 to 18 years. Ulcerative colitis was the most frequent diagnosis in EO-IBD and in 6- to 11-year-old group, whereas Crohn's disease was predominant in older children. A classification as IBD-unclassified was more common in the range 0 to 5 years compared with the other groups (P < 0.005). EO Crohn's disease showed a more frequent isolated colonic (P < 0.005) and upper gastrointestinal involvement than later-onset disease. Sixty-two percent of the patients in the 0 to 5 years range had pancolonic ulcerative colitis, compared with 38% of 6 to 11 years (P = 0.02) and 31% of 12-18 years (P = 0.002) range. No statistical difference for family history for IBD was found in the 3-year age groups. Therapies at the diagnosis were similar for all children. However, at latest follow-up, a significantly higher proportion of younger children were under steroids compared with older groups (P < 0.05). Surgical risk did not differ according to age. CONCLUSIONS EO-IBD exhibits an extensive phenotype and benefit from aggressive treatment strategies, although surgical risk is similar to later-onset disease. A family history for IBD is not common in EO disease.

Abstract
Background. The number of patients of all age brackets diagnosed with Inflammatory Bowel Disease (IBD) has risen dramatically worldwide over the past 50 years. IBD's changing epidemiology suggests that environmental factors play a major role in modifying disease expression. Aim. To review studies carried out worldwide analyzing IBD epidemiology. Methods. A Medline search indicating as keywords “Inflammatory Bowel Disease,” “epidemiology,” “natural history,” “Crohn's Disease,” “Ulcerative Colitis,” and “IBD Unclassified” was performed. A selection of clinical cohort and systematic review studies that were carried out between 2002 and 2013 was reviewed. Studies referring to an earlier date were also considered whenever the data were relevant to our review. Results. The current mean prevalence of IBD in the total population of Western countries is estimated at 1/1,000. The highest prevalence and incidence rates of IBD worldwide are reported from Canada. Just as urbanization and socioeconomic development, the incidence of IBD is rising in China. Conclusions. Multicenter national registers and international networks can provide information on IBD epidemiology and lead to hypotheses about its causes and possible management strategies. The rising trend in the disease's incidence in developing nations suggests that its epidemiological evolution is linked to industrialization and modern Westernized lifestyles.

Abstract
OBJECTIVES Increasing numbers of paediatric and adolescent patients with Crohn disease (CD) and ulcerative colitis (UC) are reported. To determine whether this observation is a consequence of a shift towards onset at a younger age, we analysed retrospective data from patients enrolled in the Swiss IBD Cohort Study (SIBDCS). PATIENTS AND METHODS The SIBDCS is a disease-based cohort in Switzerland, which collects retrospective and prospective data on a large sample of patients with inflammatory bowel disease (IBD). Patients, diagnosed from 1980, were stratified according to diagnosis of CD and UC. Age at disease onset (age at first symptoms and age at diagnosis) was analysed in relation to calendar year of disease onset. Data were extracted from physician and patient questionnaires. Linear regressions of age at disease onset by calendar year of disease onset adjusted by sex, country of birth, and education were performed. RESULTS Adjusted regression coefficients for CD and UC were significantly positive, that is, age at disease onset has increased with time. Male sex was associated with an increase in age at disease onset, and birth in Switzerland with a decrease. These associations were statistically significant. CONCLUSIONS The results from the SIBDCS do not support the hypothesis that disease onset of both CD and UC occur today at a younger age. On the contrary, our results show that there is a significant trend for age at disease onset occurring at an older age today as compared with recent decades. We conclude that the observation of increasing numbers of paediatric and adolescent patients with IBD is not caused by a trend towards disease onset at a younger age, but that this may rather be a consequence of the overall increasing incidence of these conditions.

Abstract
BACKGROUND The development of disease complications is poorly characterized in pediatric patients with Crohn's disease (CD). METHODS We retrospectively determined the cumulative incidence of stricturing and penetrating complications of CD prior to first surgery utilizing data from 989 consecutively enrolled CD patients (age 0-17 years at diagnosis) collected between January 2000 and November 2003 and stored in the Pediatric IBD Consortium Registry. RESULTS Mean age at diagnosis was 11.5 +/- 3.8 (standard deviation) years. Median follow-up time was 2.8 years. Prior to first surgery, the cumulative incidence of stricturing or penetrating complications was 27% at 5 years and 38% at 10 years from the diagnosis of inflammatory bowel disease. The cumulative incidence of complicated disease was lowest in isolated colonic disease (P = 0.009). Penetrating complications that followed stricturing complications prior to first surgery occurred within 2 years of stricturing complications (cumulative incidence was 13% at 2 years from diagnosis of stricturing disease). Stricturing complications that followed penetrating complications prior to first surgery occurred within 8 years of penetrating complications (cumulative incidence was 26% at 8 years from diagnosis of penetrating complications). CONCLUSIONS Strictures, abscesses, and fistulas are common in pediatric CD. Earlier aggressive management may be indicated. Prospective study is required to identify genetic and serologic markers that predict a patient's risk for the development of complicated disease and to determine optimal treatment regimens.

Abstract
Partial or total CD3 chain expression defects including CD3 gamma, epsilon, delta, and zeta chain are among the autosomally inherited SCID presenting with T-B+NK+ phenotype with lymphopenia. The clinical findings are generally severe in all except for CD3 gamma deficiency. Here we present a 10-month-old CD3 gamma deficient boy with IBD. The patient had suffered from intractable diarrhea, recurrent pulmonary infections and oral moniliasis since two months of age. Following the first allogeneic HSCT from his HLA-identical (6/6) sister after a reduced intensity regimen, a second transplantation was performed five months later. On day +19 after second transplantation, the CD3 TCR alpha/beta chain expression increased to 66% with development of full donor chimerism (98.6%). A significant improvement in diarrhea, perianal lesions, and rectal fistula was observed suggesting an improvement in inflammatory bowel disease. The patient died at home on day +50 with a sudden respiratory failure secondary to an undetermined infection. The case was interesting being the first reported case with SCID and inflammatory bowel disease who responded very well to HSCT by full recovery of intractable diarrhea, failure to thrive, laboratory findings, and improvement of fistula formation.

Abstract
We present a case of pancytopenia in a 9-month-old infant with total parenteral nutrition (TPN) dependence due to short bowel syndrome. Bone marrow examination revealed left-shifted myeloid maturation, erythroid and myeloid dysplasia with normal iron stores. Serum copper level was 2 microm/dl (normal range 90-190 mcg/dl). After supplementation, copper levels normalized at 143 mcg/dl, and the macrocytic anemia, neutropenia, and thrombocytopenia resolved. Copper deficiency should be considered in the differential diagnosis of cytopenias and myelodsyplasia, particularly in the growing number of pediatric patients with TPN dependency or malabsorption.

Abstract
BACKGROUND The relationship between the age at diagnosis and disease course is poorly defined in children with Crohn's disease (CD). We examined the presentation and course of disease in patients 0-5 compared to 6-17 yr of age at diagnosis. METHODS We analyzed uniform data from 989 consecutive CD patients collected between January 2000 and November 2003, and stored in the Pediatric IBD Consortium Registry. The statistical tests account for the length of follow-up of each patient. RESULTS In total, 98 patients (9.9%) were of 0-5 yr of age at diagnosis. The mean follow-up time was 5.6 +/- 5.0 yr in the younger group and 3.3 +/- 2.8 yr in the older group (P < 0.001). Race/ethnicity differed by the age group (P= 0.015); a larger proportion of the younger group was Asian/Pacific Islander or Hispanic, and a larger proportion of the older group was African American. The initial classification as ulcerative colitis or indeterminate colitis was more common among the 0-5 yr of age group (P < 0.001). The 6-17 yr of age patients presented with more abdominal pain (P < 0.001), weight loss (P= 0.001), or fever (P= 0.07), while the 0-5 yr of age patients presented with more rectal bleeding (P= 0.008). The 6-17 yr of age patients were more likely to be treated with antibiotics (P < 0.001), 6-mercaptopurine/azathioprine (P < 0.001), infliximab (P= 0.001), or corticosteroids (P= 0.0006). The 6-17 yr of age patients had a higher cumulative incidence of treatment with 5-aminosalicylates (P= 0.009) or methotrexate (P= 0.04). The risk for developing an abscess (P= 0.001), a fistula (P= 0.02), a stricture (P= 0.05), or a perianal fissure (P= 0.06) was greater in the 6-17 yr of age patients. CONCLUSIONS The 6-17 yr of age patients with CD appear to have a more complicated disease course compared to 0-5 yr of age children. The 0-5 yr of age group may represent a unique disease phenotype and benefit from different approaches to management. Long-term prospective studies are required to validate these findings.

Abstract
There is evidence that inflammatory bowel disease is immunologically mediated and that genetic factors play an important aetiological role. The identification of disease susceptibility genes has led to significant progress in our understanding of the pathogenesis of Crohn's disease. Genes linked to Crohn's disease play critical roles in the normal function of the innate immune system, and genes linked to epithelial integrity may play a role in the pathogenesis of inflammatory bowel disease as well. However, the dynamic epidemiology of both Crohn's disease and ulcerative colitis suggests that extrinsic environmental factors acting at the population level may be involved in their pathogenesis. These environmental factors may be responsible for the rising incidence of inflammatory bowel disease.
