Abstract
Inflammatory bowel disease (IBD) is a chronic gastrointestinal disorder. Oxidative stress and inflammatory responses have a vital role in the pathophysiology of IBD as well as seizure. IBD is associated with extraintestinal manifestations. This study aimed to explore the relationship between colitis and susceptibility to seizures, with a focus on the roles of neuroinflammation and oxidative stress in acetic acid-induced colitis in mice. Forty male Naval Medical Research Institute mice were divided into four groups: control, colitis, pentylenetetrazole (PTZ), and colitis + PTZ. Colitis was induced by intrarectal administration of acetic acid, and seizures were induced by intravenous injection of PTZ 7 days postcolitis induction. Following the measurement of latency to seizure, the mice were killed, and their colons and prefrontal cortex (PFC) were dissected. Gene expression of inflammatory markers including interleukin-1β, tumor necrosis factor-alpha, NOD-like receptor protein 3, and toll-like receptor 4, as well as total antioxidant capacity (TAC), malondialdehyde (MDA), and nitrite levels were measured in the colon and PFC. Histopathological evaluations were performed on the colon samples. Data were analyzed by t-test or one-way variance analysis. Colitis decreased latency to seizure, increased gene expression of inflammatory markers, and altered levels of MDA, nitrite, and TAC in both the colon and PFC. Simultaneous induction of colitis and seizure exacerbated the neuroimmune response and oxidative stress in the PFC and colon. Results concluded that neuroinflammation and oxidative stress in the PFC at least partially mediate the comorbid decrease in seizure latency in mice with colitis.

Abstract
BACKGROUND Inflammatory bowel disease is a common digestive disorder and diabetes can lead to intestinal dysfunction. Patients with inflammatory bowel disease in combination with diabetes present a higher rate of hospitalization and consumption of medical resources, yet the association between type 2 diabetes and Inflammatory bowel disease remains unknown. METHODS We studied 313,008 participants from the UK Biobank, including 5891 patients with type 2 diabetes at baseline. Multivariate Cox proportional risk models were constructed to examine the risks associated with type 2 diabetes and inflammatory bowel disease and its subtypes (Crohn's disease, ulcerative colitis). Potential confounders including sociodemographic, lifestyle, physical body indicators, psychological state, hypertension, and thyroid-related disorders were adjusted. Propensity score matching was also performed to analyze their sensitivity. RESULTS Of a total of 313,008 participants included in the study, 5891 (1.88 %) were diagnosed with type 2 diabetes mellitus at baseline and 1829 (0.58 %) of the entire cohort developed inflammatory bowel disease during follow-up, with a median follow-up time of 13.72 years. Patients with type 2 diabetes had a higher cumulative risk of inflammatory bowel disease compared to the non-type 2 diabetes population (inflammatory bowel disease: 1.24% vs. 0.57%, p < 0.001; Crohn's disease: 0.46% vs. 0.15%, p < 0.001; ulcerative colitis: 0.73% vs. 0.35%, p < 0.001). Multivariate Cox regression analysis showed that type 2 diabetes was independently associated with inflammatory bowel disease (Hazard Ratio: 1.61 [95% Confidence Interval: 1.26-2.06], p < 0.001), Crohn's disease (Hazard Ratio: 2.10 [95% Confidence Interval: 1.39-3.17], p < 0.001) and ulcerative colitis (Hazard Ratio: 1.58 [95% Confidence Interval: 1.15-2.18], p = 0.005). In a propensity-matched analysis, type 2 diabetes still showed its ability to predict the risk of inflammatory bowel disease (Hazard Ratio: 2.09 [95% Confidence Interval: 1.55-2.83], p < 0.001), Crohn's disease (Hazard Ratio: 3.49 [95% Confidence Interval: 2.00 to 6.09], p < 0.001), and ulcerative colitis (Hazard Ratio: 1.76 [95% Confidence Interval: 1.20 to 2.56], p = 0.003) of robustness. CONCLUSION In patients with type 2 diabetes mellitus, the risk of inflammatory bowel disease is higher, and the presence of gastrointestinal symptoms in patients with type 2 diabetes requires vigilance for the possibility of inflammatory bowel disease in clinical practice.

Abstract
OBJECTIVES Celiac disease (CeD) autoimmunity and coexisting inflammatory bowel disease (IBD) present a diagnostic dilemma. Our aims were to describe the phenotype of children with IBD and CeD seropositivity and evaluate provider confidence for diagnosing CeD in this population. METHODS We performed a single-center retrospective cohort study of subjects ≤18 years old with IBD and CeD seropositivity between 2006 and 2020. Subjects were considered to have IBD-CeD if they met CeD diagnosis by serology and histology per North American Society For Pediatric Gastroenterology, Hepatology and Nutrition guidelines and if providers suspected CeD as evaluated by a survey. The IBD-only cohort included seropositive participants that did not meet criteria for CeD. Demographic, histologic, gross endoscopic, and laboratory features were compared using Fisher exact test. RESULTS Of 475 children with IBD, 8 had concomitant CeD, 5 had tissue transglutaminase (tTG) immunoglobulin A (IgA) > 10x upper limit of normal (ULN, P = 0.006), and 8 had villous atrophy (VA, P = 0.003) when compared with 17 seropositive participants with IBD-only. No children with IBD-CeD had esophageal eosinophilia, duodenal cryptitis, duodenal ulceration, or fecal calprotectin >250 µg/g. Factors that contributed to provider uncertainty for diagnosing CeD in IBD included the absence of VA and intraepithelial lymphocytes, the presence of neutrophilic and eosinophilic duodenitis, diffuse ulceration, elevated inflammatory markers, and immunosuppression therapy. CONCLUSIONS Diagnosing CeD in children with IBD continues to be challenging. Although high titers of tTG IgA and VA increased provider confidence for diagnosing CeD in IBD, development of evidence-based guidelines are needed. They should better assess the importance of features atypical of concomitant CeD that contribute to uncertainty.

Abstract
Inflammatory bowel disease (IBD) is a lifelong, immune-mediated disorder that often occurs in childhood and is becoming increasingly common worldwide. Diagnosis of IBD in children remains difficult due to the spectrum of symptoms, including gastrointestinal and extraintestinal manifestations. Type 1 diabetes mellitus (T1D) is one of the most common autoimmune diseases in children and adolescents. Classic manifestations of T1D in young people include polyuria, polydipsia, abdominal pain, weight loss, and ketoacidosis. However, children with autoimmunity of pancreatic β-cells may remain euglycemic and asymptomatic for many years. An accurate and prompt diagnosis of IBD and T1D is particularly important in children because they can negatively affect growth, psychosocial function and overall well-being. We present a case in which a previously healthy child was co-diagnosed with Crohn disease and T1D during a routine pediatric evaluation in the outpatient clinic of a peripheral secondary hospital.

Abstract
OBJECTIVES Abdominal pain (AP) is a common feature in the general population. However, in patients with juvenile idiopathic arthritis (JIA) AP has scantily been studied. Among other reasons, gastrointestinal symptoms may present as side effects due to the medical treatment of JIA. The aim of the study was to explore the frequency of AP and its relationship to disease components and health-related quality of life (HRQoL) among young adults with JIA. METHODS This study included a cohort of 97 Finnish patients belonging to the population-based Nordic JIA cohort at their 17-year follow-up study visit. Mean age of the patients was 23 years. AP, functional status, fatigue, HRQoL, disease characteristics of JIA, and comorbidities were evaluated. AP was classified into three categories according to frequency: (1) never, (2) seldom (one to three times a month) and (3) frequent (at least once a week). RESULTS About 48 (50%) young adults with JIA reported AP. Seldom AP was reported by 37 (38%), and frequent AP by 11 (11%) patients. AP was significantly associated with fatigue, female gender, functional status and arthritis-related pain. Patients having frequent AP reported lower HRQoL. AP was associated with the use of methotrexate and sulfasalazine, but not with nonsteroidal anti-inflammatory drugs (NSAIDs). CONCLUSION AP is an important complaint in young adults with JIA and is associated with fatigue, female gender, methotrexate and sulfasalazine use. Patients with JIA reporting frequent AP with lower functional status and higher arthritis-related pain values have lower HRQoL.

Abstract
Diabetes comorbidity in ulcerative colitis (UC) has relevant clinical and therapeutic implications. The link between hyperglycemia and intestinal barrier function with respect to infection and inflammation consequences exists in diabetes. The present study was designed to decipher the molecular mechanisms associated with Type 1 Diabetes mellitus and the UC in both male and female BALB/c mice. Dextran sulfate sodium (DSS; 2.5%w/v) dissolved in drinking water was given for three cycles (each cycle; 7 days) with 7 days recovery period in-between to both male and female BALB/c mice. At the first recovery period, Streptozotocin (40 mg/kg; i.p.) was administered for 5 consecutive days in the case of male BALB/c mice; whereas the same procedure was repeated at the beginning of each recovery period in female animals. In the DSS + DB group of male animals, disease activity index, myeloperoxidase activity, nitrite level, plasma lipopolysaccharides, interleukin-1β, histological score, % fibrotic area, % TUNEL positive cells were significantly increased. Furthermore, protein expression of phosphorylated nuclear factor kappa light chain enhancer of activated B cells (pNFκB65), proliferating cell nuclear antigen, interleukin-6, apoptosis-associated speck-like protein containing a caspase-recruitment domain, and cysteine-containing aspartate-specific proteases-1 (caspase-1) significantly increased in the DSS + DB group of male animals as compared to female. The present study findings proved that hyperglycemic conditions exacerbated the pathological conditions in UC of male animals; whereas milder conditions developed in females.

Abstract
Background. Inflammatory bowel disease (IBD), which includes ulcerative colitis (UC) and Crohn’s disease (CD), is a chronic relapsing disease indicated by inflammation of the gastrointestinal tract. Celiac disease (CeD) is a chronic autoimmune disease of the small bowel. The prevalence of CeD in IBD patients is unknown. Some studies have described the coexistence of the 2 diseases in the same patient. This study aimed to investigate the prevalence of CeD in Saudi Arabian children with IBD. Methods. We used a retrospective study design because data can be collected immediately and is easier to analyze afterward. The study was conducted on IBD patients in the Pediatric Gastroenterology Department at National Guard Hospital, Jeddah, Saudi Arabia. We enrolled Saudi patients aged between 1 and 18 years who had been diagnosed with IBD and CeD based on positive biochemical serology and histology from January 2011 to January 2020. We excluded patients with immunodeficiency disorders. Results. Among the 46 enrolled patients with IBD, CeD was identified in 4, and they did not develop any relapses. We discovered that the weight at IBD diagnosis improved significantly compared to current weight (P-value < .0001). We also discovered that the height at diagnosis of IBD improved significantly compared to the current height (P-value < .0001). Additionally, we found no significant associations between UC and CeD (P-value = 1), or CD and CeD (P-value = .625). Conclusion. No significant associations were evident between the prevalence of CeD and IBD. More prospective multicenter studies are needed to clarify the prevalence of CeD in children with IBD.

Abstract
BACKGROUND Adult patients with both inflammatory bowel disease (IBD) and celiac disease (CeD) have peculiar phenotypic features. This study aimed at describing the characteristics and natural history of children with both IBD and CeD. METHODS This was a case-control study based on a national registry. Cases included children diagnosed with both IBD and CeD. Two matched IBD controls without CeD, and 2 matched CeD controls were selected for each case. Inflammatory bowel disease phenotype and natural history, comprising growth and pubertal development, were compared between groups. RESULTS Forty-nine (1.75%) patients with IBD and CeD were identified out of 2800 patients with IBD. Compared with patients with IBD alone, patients with IBD and CeD presented more frequently with autoimmune diseases (odds ratio, 2.81; 95% CI, 0.97-8.37; P = 0.04). Ileocolonic localization (46.1% vs 73.1%), treatment with azathioprine (46.2% vs 71.2%), and anti-TNF biologics (46.2% vs 69.2%) were less common in patients with Crohn's disease and CeD than in patients with Crohn's disease alone. Patients with ulcerative colitis and CeD had an increased risk of colectomy despite similar medical treatments compared with patients with ulcerative colitis alone (13.0% vs 0%). Pubertal delay was more common in patients with IBD and CeD compared with patients with IBD alone (14.9% vs 3.2%; odds artio, 5.24; 95% CI, 1.13-33.0; P = 0.02) and CeD alone (14.9% vs 1.1%; P = 0.002). CONCLUSIONS Children with IBD and CeD may have peculiar features with a higher risk for autoimmune diseases, colectomy, and pubertal delay compared with IBD alone.

J Neuroinflammation 2021; 18:199.

Abstract
BACKGROUND Patients with chronic inflammatory disorders such as inflammatory bowel disease frequently experience neurological complications including epilepsy, depression, attention deficit disorders, migraines, and dementia. However, the mechanistic basis for these associations is unknown. Given that many patients are unresponsive to existing medications or experience debilitating side effects, novel therapeutics that target the underlying pathophysiology of these conditions are urgently needed. METHODS Because intestinal disorders such as inflammatory bowel disease are robustly associated with neurological symptoms, we used three different mouse models of colitis to investigate the impact of peripheral inflammatory disease on the brain. We assessed neuronal hyperexcitability, which is associated with many neurological symptoms, by measuring seizure threshold in healthy and colitic mice. We profiled the neuroinflammatory phenotype of colitic mice and used depletion and neutralization assays to identify the specific mediators responsible for colitis-induced neuronal hyperexcitability. To determine whether our findings in murine models overlapped with a human phenotype, we performed gene expression profiling, pathway analysis, and deconvolution on microarray data from hyperexcitable human brain tissue from patients with epilepsy. RESULTS We observed that murine colitis induces neuroinflammation characterized by increased pro-inflammatory cytokine production, decreased tight junction protein expression, and infiltration of monocytes and neutrophils into the brain. We also observed sustained neuronal hyperexcitability in colitic mice. Colitis-induced neuronal hyperexcitability was ameliorated by neutrophil depletion or TNFα blockade. Gene expression profiling of hyperexcitable brain tissue resected from patients with epilepsy also revealed a remarkably similar pathology to that seen in the brains of colitic mice, including neutrophil infiltration and high TNFα expression. CONCLUSIONS Our results reveal neutrophils and TNFα as central regulators of neuronal hyperexcitability of diverse etiology. Thus, there is a strong rationale for evaluating anti-inflammatory agents, including clinically approved TNFα inhibitors, for the treatment of neurological and psychiatric symptoms present in, and potentially independent of, a diagnosed inflammatory disorder.

Abstract
Systemic autoimmune disorders occur more frequently in patients with epilepsy than in the general population, suggesting shared disease mechanisms. The risk of epilepsy is elevated across the spectrum of systemic autoimmune disorders but is highest in systemic lupus erythematosus and type 1 diabetes mellitus. Vascular and metabolic factors are the most important mediators between systemic autoimmune disorders and epilepsy. Systemic immune dysfunction can also affect neuronal excitability, not only through innate immune activation and blood-brain barrier dysfunction in most epilepsies but also adaptive immunity in autoimmune encephalitis. The presence of systemic autoimmune disorders in subjects with acute seizures warrants evaluation for infectious, vascular, toxic and metabolic causes of acute symptomatic seizures, but clinical signs of autoimmune encephalitis should not be missed. Immunosuppressive medications may have antiseizure properties and trigger certain drug interactions with antiseizure treatments. A better understanding of mechanisms underlying the co-existence of epilepsy and systemic autoimmune disorders is needed to guide new antiseizure and anti-epileptogenic treatments. This review aims to summarize the epidemiological evidence for systemic autoimmune disorders as comorbidities of epilepsy, explore potential immune and non-immune mechanisms, and provide practical implications on diagnostic and therapeutic approach to epilepsy in those with comorbid systemic autoimmune disorders.

Abstract
BACKGROUND Previous studies showed inconsistent results regarding associations between inflammatory bowel disease (IBD) and risk of ischemic heart disease (IHD) and diabetes. The present study aimed to make a meta-analysis to assess the risk of IHD and diabetes in IBD. METHODS We searched for articles published before February 2020 in the databases as follows: PubMed, Web of Science, Medline, EMBASE, and Google Scholar. We computed odds ratio (OR) or relative risk (RR) and 95 % confidence intervals (CI) regarding the association between IBD and risk of IHD or diabetes by using STATA 13.0 software. RESULTS The present meta-analysis showed that IBD was associated with higher risk of IHD (OR/RR = 1.26, 95 % CI 1.20 to 1.32, I2 = 88.3 %, p < 0.0001). Additionally, both ulcerative colitis (UC) and Crohn's disease (CD) were associated with higher risk of IHD (UC: OR/RR = 1.19, 95 % CI 1.13 to 1.26, I2 = 65.6 %, p = 0.001; CD: OR/RR = 1.33, 95 % CI 1.17 to 1.51, I2 = 89.5 %, p < 0.0001). The study showed that IBD was associated with elevated risk of diabetes (OR/RR = 1.26, 95 % CI 1.03 to 1.53, I2 = 92.1 %, I2 = 92.1 %, p < 0.0001). Additionally, both UC and CD were associated with higher risk of diabetes (UC: OR/RR = 1.33, 95 % CI 1.03 to 1.71, I2 = 93.8 %, p < 0.0001; CD: OR/RR = 1.39, 95 % CI 1.10 to 1.76, I2 = 76.7 %, p = 0.002). CONCLUSION In conclusion, patients with IBD are at increased risk of IHD and diabetes. Thus, regular monitoring of biomarkers of IHD and blood glucose levels should be considered for the early detection of IHD and diabetes in IBD patients.

Abstract
BACKGROUND & AIMS There is controversy over the association between celiac disease (CeD) and inflammatory bowel diseases (IBD). We performed a systematic review and meta-analysis to assess evidence for an association between CeD and IBD. METHODS We searched databases including MEDLINE, EMBASE, CENTRAL, Web of Science, CINAHL, DARE, and SIGLE through June 25, 2019 for studies assessing the risk of CeD in patients with IBD, and IBD in patients with CeD, compared with controls of any type. We used the Newcastle-Ottawa Scale to evaluate the risk of bias and GRADE to assess the certainty of the evidence. RESULTS We identified 9791 studies and included 65 studies in our analysis. Moderate certainty evidence found an increased risk of CeD in patients with IBD vs controls (risk ratio [RR] 3.96; 95% confidence interval [CI] 2.23-7.02) and increased risk of IBD in patients with CeD vs controls (RR 9.88; 95% CI 4.03-24.21). There was low-certainty evidence for the risk of anti-Saccharomyces antibodies, a serologic marker of IBD, in patients with CeD vs controls (RR 6.22; 95% CI 2.44-15.84). There was low-certainty evidence for no difference in risk of HLA-DQ2 or DQ8 in patients with IBD vs controls (RR 1.04; 95% CI 0.42-2.56), and very low-certainty evidence for an increased risk of anti-tissue transglutaminase in patients with IBD vs controls (RR 1.52; 95% CI 0.52-4.40). Patients with IBD had a slight decrease in risk of anti-endomysial antibodies vs controls (RR 0.70; 95% CI 0.18-2.74), but these results are uncertain. CONCLUSIONS In a systematic review and meta-analysis, we found an increased risk of IBD in patients with CeD and increased risk of CeD in patients with IBD, compared with other patient populations. High-quality prospective cohort studies are needed to assess the risk of CeD-specific and IBD-specific biomarkers in patients with IBD and CeD.

Abstract
Introduction The association between inflammatory bowel disease (IBD) - particularly its two main subtypes, ulcerative colitis (UC) and Crohn’s disease (CD) - and celiac disease (CeD) has been attributed to an overlap in the mechanism of immune dysregulation that characterizes these conditions. Owing to the paucity of studies that have explored this condition in pediatric patients, we examined the prevalence of CeD in children with IBD. Materials and methods This is a cross-sectional study of children aged two to 18 years with IBD that were diagnosed between 2016 and 2018. Clinical, demographic, laboratory, and endoscopic data were analysed. Serology for CeD measured the immunoglobulin A tissue transglutaminase (IgA-tTG) antibodies, and the diagnosis was confirmed histologically through small bowel biopsies. Results The study included 101 patients with IBD (83.2% with UC and 16.8% with CD). The mean age was 8.7±4.0 years. Males constituted 59.4% of the cohort, and only 3% had perianal disease. Ileocolonic involvement was reported in 64.7% and non-stricturing and non-penetrating behaviour in 76.7% of CD patients. Pancolitis constituted 45.2% of UC patients. Ten patients (9.9%) had positive serology based on IgA-tTG antibodies, three (approximately 3%) had CeD based on biopsy findings, two patients (2%) had CD, and one patient (1%) had UC. Patients with confirmed CeD had a significantly higher frequency of symptoms of gaseous sensation and bloating (P=0.003) and abdominal distension (P=0.04). Conclusions The prevalence of CeD in Egyptian children with IBD is higher than previously reported in a number of similar studies. Abdominal bloating and gaseous sensation were identified as associated symptoms.

Abstract
OBJECTIVES Celiac disease can occur in children with inflammatory bowel disease (IBD) and poses a diagnostic challenge. We evaluated the presence of anti-tissue transglutaminase (tTG) antibodies and celiac disease among children with IBD. METHODS In a retrospective chart review, we assessed the prevalence of tTG antibodies and celiac disease and compared with a control group of children with gastrointestinal symptoms without IBD. RESULTS Study population included 130 children with IBD and 257 in the control group. Abnormal tTG levels were found in 6 and 20 patients, respectively (4.6% vs 7.8%, P = 0.24). One patient with IBD and 12 in the control group had celiac disease (0.8% vs 4.7%, P = 0.07). CONCLUSIONS False-positive tTG can occur in children with IBD. The prevalence of celiac disease is not increased in children with IBD compared with non-IBD children with gastrointestinal symptoms and is similar to that in the general population.

Abstract
ABSTRACT BACKGROUND: Celiac disease is an immune-mediated disorder with a multiform presentation and therefore a challenging diagnosis. OBJECTIVE: Our purpose is to identify the epidemiological, clinical, laboratory and histologic characteristics of children with celiac disease at diagnosis and on follow-up. METHODS: Children with previously established or newly diagnosed celiac disease, admitted in a tertiary centre in a two-year period (2014-2016) were recruited. Data was collected retrospectively from electronic medical records and clinical notes, and subsequently analysed with SPSS version 20.0. RESULTS: A total of 159 patients, out of 312, were included. Age ranged from 1 to 17 years (mean ± SD: 8.5±4.5 years, 69% girls). Disease presentation was classical in 60%, non-classical in 25%, subclinical in 10% and 5% classified as potential celiac disease. Non-classical and subclinical profiles had a higher mean age at presentation but not statistically significant (P-value 0.24). The most frequent gastrointestinal features at presentation were abdominal pain (58%), diarrhea (43%) and bloating (27%). A positive family history for celiac disease was present in 24% (n=35). We found anaemia in 23%, low ferritin in 63% and a moderate to severe deficiency of 25-hydroxyvitamin D in 62%. celiac disease -specific serologic testing and esophagogastroduodenoscopy were performed in 99%. Histology revealed modified Marsh 2 or 3 enteropathy in 94%, the remaining had normal histology but positive human leukocyte antigen typing. Clinical improvement at 12 months of gluten-free diet was complete in 51% and partial in 49%. IgA tTG normalized after 12-30 months of gluten-free diet in 45%. On growth assessment at diagnosis and after 12-28 months of gluten-free diet, 100% had height increase (mean ±SD: 7.11±4.43 cm) and 96% weight gain (mean ±SD: 5.60±4.91 kg). CONCLUSION: Our findings outline the diverse clinical presentations of pediatric celiac disease that should be considered irrespective of age. Increased clinician’s awareness will enable an early diagnosis and treatment, with subsequent symptom and nutritional status improvement.

Abstract
Diabetic kidney disease (DKD) is a devastating condition associated with increased morbidity and premature mortality. The etiology of DKD is still largely unknown. However, the risk of DKD development and progression is most likely modulated by a combination of genetic and environmental factors. Patients with autoimmune diseases, like type 1 diabetes, inflammatory bowel disease, and celiac disease, share some genetic background. Furthermore, gastrointestinal disorders are associated with an increased risk of kidney disease, although the true mechanisms have still to be elucidated. Therefore, the principal aim of this review is to evaluate the impact of disturbances in the gastrointestinal tract on the development of renal disorders.

Abstract
BACKGROUND Celiac disease (CD) has been linked to inflammatory bowel disease (IBD) but previous reports have been inconsistent and may have been affected by surveillance bias. METHODS Matched birth cohort study in Friuli-Venezia Giulia Region, Italy. We identified 1294 individuals with CD aged 0 to 23 years at diagnosis using pathology reports, hospital discharge records, or copayment exemptions. Each CD individual was matched with up to 5 general population reference individuals from the regional Medical Birth Register in Friuli-Venezia Giulia (n = 5681). As secondary comparison groups, we used individuals undergoing small intestinal biopsy but not having villous atrophy (either Marsh 0-1-2 or exclusively Marsh 0). Individuals with IBD were identified through hospital discharge records or copayment exemptions. Conditional logistic regression was used to estimate odds ratios (ORs) for having IBD among CD individuals (before or after CD diagnosis) compared with their matched references. RESULTS Overall 35 individuals with IBD were identified (29 with CD and 6 general population controls). This corresponded to an increased risk of IBD in CD (OR = 24.17; 95% CI, 10.03-58.21). However, compared with individuals with Marsh 0-1-2 the OR decreased to 1.41 (95% CI, 0.91-2.18) and restricting our comparison group to individuals with Marsh 0, the OR was 1.28 (95% CI, 0.61-2.70). CONCLUSIONS In conclusion, this article found a highly increased risk of IBD in individuals with CD when comparing with the general population. Bias is the likely explanation for the very high risk increase for IBD in CD because the excess risk was substantially lower when we used individuals with a small intestinal biopsy without villous atrophy as our reference.

Abstract
AIM Celiac disease (CD) is a systemic disorder that is associated with various autoimmune disorders and a higher prevalence of other diagnoses and complications. This large, cross-sectional, population-based study investigated the associations between CD and various medical conditions during late adolescence. METHODS We included 2 001 353 Jewish Israeli adolescents who underwent a general health examination at a median age of 17.1 (16.9-17.4) years from 1988 to 2015. Comprehensive data regarding medical status were available for 1 588 041 (79%) subjects. A definite diagnosis of CD was based on accepted criteria. Covariate data included demographic measures and data on associated medical conditions. RESULTS Overall, data on 7145 subjects with CD and 1 580 896 controls were analysed. Multivariate analyses showed that autoimmune diseases were significantly more common in subjects with CD, including insulin dependent diabetes, with an odds ratio (OR) of 5.5, inflammatory bowel diseases (OR = 3.8), arthritis (OR = 2.4), thyroid diseases (OR = 1.8) and psoriatic skin disorders (OR = 1.6). Further associations included asthma (OR = 1.5), bile stones (OR = 3.6), migraine (OR = 2.3), anaemia (OR = 1.7) and menstrual abnormalities (OR = 1.5). Long bone fractures and axial fractures were no more common in adolescents with CD than controls. CONCLUSION CD was already associated with multiple comorbidities by adolescence, and these were not limited to autoimmune disorders.

Abstract
Objective.Antitumor necrosis factor-α (anti-TNF-α) therapy is the most prescribed biologic agent therapy in rheumatology and gastroenterology. However, a number of serious side effects have been reported with these drugs. Only a handful of cases of new-onset inflammatory bowel disease (IBD), mostly in children diagnosed with juvenile idiopathic arthritis (JIA), have been reported during anti-TNF-α therapy. We present 3 cases of adult IBD following anti-TNF-α therapy and a literature review on this topic.Methods.We searched PubMed MESH for all relevant terms, papers were reviewed, and patient-specific data were extracted. Relevant clinical data were calculated and presented.Results.The PubMed search resulted in 137 articles, of which 11 articles and 4 cited publications were included in our analysis. We found 53 cases of IBD after anti-TNF-α therapy reported in the literature; most of them were case series collected retrospectively from national databases or studies. Almost all the patients developed IBD after the introduction of etanercept (ETN); 2 patients with rheumatoid arthritis were also included. The average age at IBD onset was 17.3 years and the average time from ETN introduction to IBD onset was 27 months (± 24). Gastrointestinal symptoms have been reported as improving or subsiding in most of the patients after discontinuing ETN.Conclusion.Although this manifestation is not common, it should be taken into consideration as an adverse effect of ETN. Rheumatologists, and in particular rheumatologists treating adult patients, should be aware of this possible complication. Further investigation about the pathogenic process underlying this phenomenon is warranted.

Epilepsy Behav 2016; 63:29-33. [PMID: 27552483 DOI: 10.1016/j.yebeh.2016.05.041] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2016] [Revised: 05/11/2016] [Accepted: 05/11/2016] [Indexed: 12/18/2022]
Abstract
PURPOSE Epilepsy is known to be associated with affective disorders and sleep alterations, as well as with gastrointestinal conditions such as peptic ulcers and inflammatory bowel disease. There is comparatively little evidence linking epilepsy and gastrointestinal functional disorders. The objective of this study was to determine the prevalence and impact of irritable bowel syndrome (IBS) in patients with epilepsy. METHODS We carried out a cross-sectional observational study on 65 consecutive people with epilepsy (PWE) and age- and sex-matched controls. Irritable bowel syndrome and functional dyspepsia (FD) diagnosis were based on Rome III criteria. Clinical and demographic characteristics were recorded, and instruments evaluating sleep quality, depressive/anxiety symptoms, insomnia, and health-related quality of life were also completed. RESULTS Irritable bowel syndrome prevalence was significantly different between groups (3% in controls and 16% in patients with epilepsy; p=0.04), while no difference was found in FD (2% vs. 6%, respectively). People with epilepsy with IBS had significantly more insomnia and depressive and anxiety symptoms. No demographic or clinical characteristics were significantly different between groups. The presence of IBS did not affect health-related quality of life in PWE. On multivariate analysis, insomnia and depressive and anxiety symptoms did not independently predict IBS diagnosis. CONCLUSION Irritable bowel syndrome was more frequent in PWE compared with that in healthy controls. Irritable bowel syndrome does not appear to affect health-related quality of life but is associated with a greater burden of affective symptoms and insomnia.

Abstract
PURPOSE To investigate the association between systemic autoimmune diseases (SAD) and epilepsy and to determine whether the strength of this association is increased in the young. METHODS A meta-analysis was done, analyzing the association between epilepsy and SAD using the available data in Medline and Embase through February 2016. We followed the recommendations of the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement and the MOOSE (meta-analysis of observational studies in epidemiology) guidelines. RESULTS A total of twenty-five studies met the inclusion criteria for this meta-analysis, which included 10,972 patients with epilepsy (PWE) and 2,618,637 patients with SAD. The PWE cohort was shown to have more than a 2.5-fold increased risk of SAD. The patients with SAD were also shown to have a more than 2.5-fold increased risk of epilepsy. The results indicated that patients <20 years of age had a 3-fold increased risk of SAD and epilepsy (OR=3.04 [95% CI 1.27-7.27], P=0.01; OR=3.15 [95% CI 1.92-5.15], P<0.01; respectively), and these risks were shown to be higher than patients >20 years of age. The PWE cohort had a 2.6-fold increased risk of celiac disease (OR=2.65 [95% CI 1.41-4.97], P<0.01). The patients with systemic lupus erythematosus had a 4.5-fold increased risk of epilepsy (OR=4.57 [95% CI 2.40-8.67], P<0.01). CONCLUSIONS There is an association between epilepsy and SAD, which was shown to be stronger at a young age.

Abstract
INTRODUCTION The number of pediatric patients with inflammatory bowel disease (IBD), namely Crohn´s disease, ulcerative colitis and unclassified colitis, has rapidly increased in Western countries. Areas covered: This review discusses how the treatment of pediatric IBD patients has improved,with attention given to therapeutic quality and cost. The literature search covers Medline-PubMed and the Cochrane Library, with February 2016 as the last search dates. Similarly to what has been the trend in the management of adult IBD, pediatric IBD therapy has become more active than before. High use of immunosuppressants and the availability of biological therapeutic agents has helped to control the extensive and aggressive course of pediatric IBD. Full disease control at an early phase has advantages such as preserving normal child growth and development, maintaining overall good health and quality of life, as well as decreasing the psychosocial burden of the disease. Expert commentary: A key research direction is to tailor treatment modalities according to anticipated individual phenotype and disease course. Another is to reduce healthcare costs by decreasing the so-far high rate of surgery of pediatric IBD patients, and, instead, to develop a more active approach to treatment than before.

Risks of hospitalization and drug consumption in children and young adults with diagnosed celiac disease and the role of maternal education: a population-based matched birth cohort study. BMC Gastroenterol 2016; 16:1.

Abstract
BACKGROUND Celiac disease (CD) may affect healthcare use in children and young adults. Socio-economic factors may act as a confounder or effect modifier. We assessed such hypotheses in a population-based birth cohort of young celiac subjects and references matched by maternal education. METHODS The cohort included all newborns recorded in the Medical Birth Register of Friuli-Venezia Giulia Region (Italy) between 1989 and 2011. CD incident cases were identified through pathology reports, hospital discharges and copayment exemptions and matched with up to five references by sex, year of birth and maternal education. Cox regression models were used to estimate Hazard Ratios (HRs) for major causes of inpatient diagnosis and drug prescription occurring after diagnosis in CD patients compared to references, stratifying by time of first event and maternal education. RESULTS We identified 1294 CD cases and 5681 references. CD cases had a higher risk of hospital admission for any cause (HR: 2.34; 95 % CI 2.08-2.63) and for all major ICD9-CM categories except obstetric complications, skin and musculoskeletal diseases, and injuries and poisoning. Prescription of all major ATC drug categories, except dermatologicals and genito-urinary medications, was significantly increased in CD subjects. For most outcomes, HRs were highest in the first year after CD diagnosis but remained significant after five or more years. HRs were similar across different categories of maternal education. CONCLUSIONS Diagnosed CD subjects had a higher risk of hospitalization and medication use compared to the general population, even five or more years after diagnosis, with no effect modification of maternal education.

Abstract
This review summarizes the immunological consequences of biological therapies used in juvenile idiopathic arthritis (JIA). For every frequently used biological agent the characteristics are clearly specified (molecular target, isotype, registered indication for JIA, route of administration, half-life, contraindication, very common side effects, expected time of response and average cost in the first year). The emphasis of this review is on the immunological side effects that have been encountered for every separate agent in JIA populations. For each agent these adverse events have been calculated as incidence per 100 patient-years for the following categories: serious infections, tuberculosis, malignancies, response to vaccination, new-onset autoimmune diseases and development of anti-drug antibodies. There are large differences in side effects between various agents and there is a clear need for an international and standardized collection of post-marketing surveillance data of biologicals in the vulnerable group of JIA patients. Such an international pharmacovigilance database, called Pharmachild, has now been started.

Abstract
We identified a total of 595 Finnish children born in 1994-2008 and diagnosed as having inflammatory bowel disease (IBD) by October 2010 from the National Reimbursement Register (based on certificates including the diagnostic criteria) to determine whether the presence of cow's milk allergy (CMA) or asthma is associated with the risk of contracting IBD (altogether 2380 matched controls). A diagnosis of CMA in infancy was associated with Crohn disease (odds ratio [OR] 1.92, confidence interval [CI] 1.09-3.36, P < 0.05) and ulcerative colitis (OR 1.71, CI 1.04-2.83, P < 0.05), but childhood asthma only with Crohn disease (OR 2.33, CI 1.41-3.86, P = 0.001). Thus, CMA in infants is a risk factor for contracting pediatric IBD and accordingly, asthma for Crohn disease.
