Abstract
TNF-α inhibitors (TNFis) have revolutionized the treatment of certain chronic immune-mediated diseases, being widely and successfully used in rheumatic inflammatory diseases, and have also proved their efficacy in the treatment of inflammatory bowel disease (IBD). However, among the side effects of these agents are the so-called paradoxical effects. They can be defined as the appearance or exacerbation of a pathological condition that usually responds to this class of drug while treating a patient for another condition. A wide range of paradoxical effects have been reported including dermatological, intestinal and ophthalmic conditions. The causal mechanism of occurrence may implicate an imbalance of cytokines, but is still not fully understood, and remains a matter of debate. These paradoxical reactions often show improvement on discontinuation of the medication or on switching to another TNFi, but in some cases it is a class effect that could lead to the withdrawal of all anti-TNF agents. Close monitoring of patients treated with TNFis is necessary in order to detect paradoxical reactions. In this study we focus on reviewing IBD occurrence as a paradoxical effect of TNFi therapy in patients with rheumatological diseases (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and juvenile idiopathic arthritis).

Abstract
BACKGROUND Since the introduction of anti-tumour necrosis factor [TNF] therapy in inflammatory diseases, paradoxical reactions are increasingly being reported. One of these paradoxical reactions is the development of sarcoidosis-like lesions. This presentation is paradoxical since anti-TNF therapy can also be therapeutic in refractory cases of sarcoidosis. METHODS We report two cases of sarcoidosis-like lesions under anti-TNF therapy. Both were patients with inflammatory bowel disease [IBD], treated successfully with adalimumab. Next, we reviewed the literature for similar cases. Medical subject heading terms 'adalimumab', 'infliximab', 'etanercept', 'golimumab' or 'certolizumab', and 'sarcoidosis' were used to perform key word searches of the PubMed database. RESULTS We identified 90 reported cases of sarcoidosis-like lesions, which developed during anti-TNF therapy. In most cases, the anti-TNF drug involved was etanercept. The median age was 43 years and there was a predominance of female patients. The underlying disease was rheumatoid arthritis in most cases, followed by ankylosing spondylitis and psoriasiform arthritis. In six cases, the underlying disease was IBD. In 71 cases there was at least a partial resolution by discontinuation of the anti-TNF treatment, initiation of steroids or both. Re-initiation of anti-TNF therapy gave relapse in seven out of 20 cases. CONCLUSION Sarcoidosis-like lesions are increasingly reported during anti-TNF treatment. Vigilance is appropriate when patients present with symptoms compatible with sarcoidosis.

Abstract
Growth failure is frequently encountered in children with chronic inflammatory conditions like juvenile idiopathic arthritis, inflammatory bowel disease, and cystic fibrosis. Delayed puberty and attenuated pubertal growth spurt are often seen during adolescence. The underlying inflammatory state mediated by proinflammatory cytokines, prolonged use of glucocorticoid, and suboptimal nutrition contribute to growth failure and pubertal abnormalities. These factors can impair growth by their effects on the GH-IGF axis and also directly at the level of the growth plate via alterations in chondrogenesis and local growth factor signaling. Recent studies on the impact of cytokines and glucocorticoid on the growth plate further advanced our understanding of growth failure in chronic disease and provided a biological rationale of growth promotion. Targeting cytokines using biological therapy may lead to improvement of growth in some of these children, but approximately one-third continue to grow slowly. There is increasing evidence that the use of relatively high-dose recombinant human GH may lead to partial catch-up growth in chronic inflammatory conditions, although long-term follow-up data are currently limited. In this review, we comprehensively review the growth abnormalities in children with juvenile idiopathic arthritis, inflammatory bowel disease, and cystic fibrosis, systemic abnormalities of the GH-IGF axis, and growth plate perturbations. We also systematically reviewed all the current published studies of recombinant human GH in these conditions and discussed the role of recombinant human IGF-1.

The NOD2 Single Nucleotide Polymorphism rs72796353 (IVS4+10 A>C) Is a Predictor for Perianal Fistulas in Patients with Crohn's Disease in the Absence of Other NOD2 Mutations. PLoS One 2015; 10:e0116044. [PMID: 26147989 PMCID: PMC4493062 DOI: 10.1371/journal.pone.0116044] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2014] [Accepted: 12/01/2014] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND A previous study suggested an association of the single nucleotide polymorphism (SNP) rs72796353 (IVS4+10 A>C) in the NOD2 gene with susceptibility to Crohn's disease (CD). However, this finding has not been confirmed. Given that NOD2 variants still represent the most important predictors for CD susceptibility and phenotype, we evaluated the association of rs72796353 with inflammatory bowel disease (IBD) susceptibility and the IBD phenotype. METHODOLOGY Genomic DNA from 2256 Caucasians, including 1073 CD patients, 464 patients with ulcerative colitis (UC), and 719 healthy controls, was genotyped for the NOD2 SNP rs72796353 and the three main CD-associated NOD2 mutations rs2066844, rs2066845, and rs2066847. Subsequently, IBD association and genotype-phenotype analyses were conducted. RESULTS In contrast to the strong associations of the NOD2 SNPs rs2066844 (p=3.51 x 10(-3)), rs2066845 (p=1.54 x 10(-2)), and rs2066847 (p=1.61 x 10(-20)) with CD susceptibility, no significant association of rs72796353 with CD or UC susceptibility was found. However, in CD patients without the three main CD-associated NOD2 mutations, rs72796353 was significantly associated with the development of perianal fistulas (p=2.78 x 10(-7), OR 5.27, [95% CI 2.75-10.12] vs. NOD2 wild-type carriers). CONCLUSION/SIGNIFICANCE Currently, this study represents the largest genotype-phenotype analysis of the impact of the NOD2 variant rs72796353 on the disease phenotype in IBD. Our data demonstrate that in CD patients the IVS4+10 A>C variant is strongly associated with the development of perianal fistulas. This association is particularly pronounced in patients who are not carriers of the three main CD-associated NOD2 mutations, suggesting rs72796353 as additional genetic marker for the CD disease behaviour.

Abstract
The relation of Mycobacterium avium ss paratuberculosis (MAP) to Crohn's Disease (CD) and other MAP-associated conditions remains controversial. New data, coupled with the analogous Helicobacter pylori (H. pylori) story, has permitted us to piece together the MAP puzzle and move forward with a more scientific way of treating inflammatory bowel disease, particularly CD. As infection moves centre stage in inflammatory bowel disease, the dated "aberrant reaction" etiology has lost scientific credibility. Now, our growing understanding of MAP-associated diseases demands review and articulation. We focus here on (1) the concept of MAP-associated diseases; (2) causality, Johne Disease, the "aberrant reaction" hypothesis; and (3) responses to published misconceptions questioning MAP as a pathogen in CD.

Abstract
PURPOSE A two-allele haplotype of TC (OCTN1 rs1050152 and OCTN2 -207G→C) is associated with Crohn's disease (CD). The association has been replicated in different populations, but also failed in some studies. The present study is to replicate the association of OCTN1 rs1050152 and examine another variant rs272879 with familial and sporadic inflammatory bowel disease (IBD) in a cohort from central Pennsylvania, USA. METHODS The study samples (n=465) included 212 inflammatory bowel disease patients (CD=115, UC=97), including 103 familial (CD=55, UC=46) and 111 sporadic (CD=60, UC=51) IBD, 139 non-IBD family members from a familial IBD registry, and 114 unrelated healthy controls. A total of 12 OCTN1 variants within exonic sequences were examined. Two nonsynonymous SNPs, rs1050152 (L503F) and rs272879 (L395V) were genotyped by a PCR-based RFLP/cRFLP method and statistically analyzed. These samples with an additional 141 unrelated healthy samples were also genotyped for rs1050152 using the SNPlex™ Genotyping System. RESULTS The OCTN1 rs1050152 is associated with CD (OR=1.745, 95% CI=1.019-2.990, χ²=4.129, p=0.042) and with IBD (OR=1.68, 95% CI=1.052-2.676, χ²=4.732, p=0.030); while the variant rs272879 is not associated with IBD, CD or ulcerative colitis (UC). The distribution of the rs1050152 variant showed a high level of the T allele in male UC (OR=2.585, 95% CI=1.139-5.869, p=0.023) and IBD (OR=2.039, 95% CI=1.024-4.059, p=0.042) patients, and in female CD patients (OR=2.329, 95% CI=1.038-5.226, ρ value=0.039). CONCLUSION The present results replicated the association of the OCTN1 rs1050152 (L503F) variant with CD and IBD overall. A weak gender-specific effect of rs1050152 (L503F) on male UC and female CD was observed.

Abstract
BACKGROUND Disease behavior in Crohn's disease (CD) may be modified by disease location and genotype. Disease behavior may change over time, and thus analysis requires follow-up. To date, there have been few pediatric studies that have evaluated the association between disease behavior and genotype with prolonged follow-up. The aim of our study was to evaluate the effect of genotype, phenotype, and ethnicity on disease behavior in pediatric CD. METHODS Evaluation of 128 pediatric CD was followed by analysis of 232 pediatric and adult-onset CD patients. Inclusion required at least 2 years of follow-up. Phenotype, ethnicity, and disease duration were recorded. Patients were genotyped for polymorphisms in the NOD2/CARD15 gene. RESULTS Colonic involvement was more frequent in younger patients. Pediatric disease at end of follow-up was classified as inflammatory (78%), penetrating (7%), and stricturing (17%). Duration of follow-up (mean 4.9 pediatric and 6.4 years mixed) was associated with more stricturing and penetrating disease. There was no association between mean age of onset and NOD2/CARD15, or either of these with disease behavior. These observations were replicated in the mixed cohort. Sephardic Jewish origin was inversely correlated with inflammatory behavior (P = 0.006), independent of NOD2/CARD15 genotype. CONCLUSIONS Duration of disease and ethnicity, irrespective of NOD2/CARD15 genotype and age of onset, were the only predictors for penetrating or stricturing disease.

Abstract
OBJECTIVES To report on the clinical evolution of a patient with ankylosing spondylitis (AS) treated with etanercept who subsequently developed Crohn's disease, to review the literature for similar cases, and to discuss possible mechanisms responsible for these observations. METHODS We describe the medical history, diagnostic tests, and disease progression of a 26-year-old man with AS who developed the clinical manifestations of Crohn's disease after 16 months of successful treatment of his rheumatologic symptoms with etanercept. A Medline search, as well as cases presented in abstract form at European Leaque Against Rheumatism (EULAR) and American College of Rheumotology (ACR) meetings, describing emergent bowel symptoms in patients treated with etanercept was undertaken. RESULTS Eight other cases were identified, with gastrointestinal symptoms appearing after a few weeks to several years, while receiving etanercept treatment. These observations raise the possibility that etanercept unmasks inflammatory bowel disease in patients with AS whose gastrointestinal symptoms were silent. CONCLUSION The reactivation or the unmasking of gastrointestinal symptoms during etanercept treatment raises the issue of differences between etanercept and the other antitumor necrosis factor monoclonal antibodies in their molecular structure, tumor necrosis factor neutralizing effect, mode of administration, and pharmacokinetics that may account for these observations.

Abstract
The human leukocyte antigen (HLA) region has been implicated in the disease susceptibility of inflammatory bowel disease by several linkage and association studies. In Caucasians, HLA-DRB1 has been reported to determine the clinical phenotypes of ulcerative colitis (UC). Others and we previously reported that HLA-DRB1*1502 was strongly associated with UC in the Japanese population. However, the contribution of HLA-DRB1 to the clinical phenotypes in Japanese UC has not been elucidated yet. The aim of this study was to determine whether HLA-DRB1 alleles were associated with the clinical phenotypes in Japanese patients with UC. A total of 353 patients with UC were recruited. Patients were classified into subgroups by sex, age at diagnosis, disease extent, need for steroid therapy or need for surgical treatment. The allele frequency of HLA-DRB1*08 was significantly higher in patients whose disease extended beyond the rectum (left-sided and extensive UC) than in those with proctitis [odds ratio (OR)=2.20, Pc=0.043). The allele frequency of HLA-DRB1*09 was significantly higher in patients with UC diagnosed at the age of 40 years or older than in those with UC diagnosed before the age of 40 years (OR=2.31, Pc=0.022). Besides these positive associations, no significant differences were found in the allele frequencies between the other subgroups. We conclude that HLA-DRB1*09 is associated with the age at diagnosis and HLA-DRB1*08 is associated with the disease extent of UC in Japanese. These results indicate that HLA-DRB1 is not only associated with the overall UC susceptibility but also associated with the clinical phenotypes in Japanese.

Abstract
OBJECTIVES The natural history of paediatric inflammatory bowel diseases (IBDs) is poorly understood. We aim to describe the disease course in this cohort and generate prognostic information for patients and clinicians. MATERIALS AND METHODS Patient records from 6 tertiary paediatric gastroenterology centres were reviewed to generate data concerning original diagnosis, change in diagnosis, family history, surgical interventions, growth, and presence of extragastrointestinal manifestations. RESULTS Data were collected on 116 children with Crohn disease (CD), 74 with ulcerative colitis (UC), and 20 with indeterminate colitis (IC), followed for a mean period of 3.42, 3.3, and 2.9 years from date of diagnosis, respectively. A male predominance is demonstrated in CD. Revision of diagnosis in patients with IC is mainly to UC, with most children receiving a definitive diagnosis within 2 years of initial presentation. Of the children with UC, 17.6% underwent 1 or more major operations with a median time to surgery of 1.92 years. Of children with CD, 11.6% underwent 1 or more major intraabdominal procedures with a median time to surgery of 1.83 years. We recorded a positive family history in 2.7%, 8.2%, and 10% of cases for CD, UC, and IC, respectively. For both boys and girls with CD, but only for boys with UC, height standard deviation score became more negative over time. CONCLUSIONS This retrospective study quantifies certain distinctions between IBDs diagnosed in paediatric and adult populations. We document a trend toward male predominance in children with CD. We also note impaired linear growth in children with CD, whereas it appears maintained in girls with UC. We also have recorded a low incidence of IBDs in the families of this cohort and suggest that environmental influences may be of greater importance. We document that major intraabdominal surgery may be required in about 15% of patients with either UC or CD within 2 years of diagnosis, and that the majority of those diagnosed initially with IC will be reclassified as either UC or CD within 2 years.

Abstract
BACKGROUND The role of the single nucleotide polymorphisms (SNPs) on positions 2677G>T/A and 3435C>T of the multi-drug-resistance gene 1 (MDR1) in inflammatory bowel disease (IBD) remains unclear. AIMS To further elucidate the potential impact of MDR1 two-locus genotypes on susceptibility to IBD and disease behaviour. PATIENTS AND METHODS Three hundred eighty-eight German IBD patients [244 with Crohn's disease (CD), 144 with ulcerative colitis (UC)] and 1,005 German healthy controls were genotyped for the two MDR1 SNPs on positions 2677G>T/A and 3435C>T. Genotype-phenotype analysis was performed with respect to disease susceptibility stratified by age at diagnosis as well as disease localisation and behaviour. RESULTS Genotype distribution did not differ between all UC or CD patients and controls. Between UC and CD patients, however, we observed a trend of different distribution of the combined genotypes derived from SNPs 2677 and 3435 (chi(2) = 15.997, df = 8, p = 0.054). In subgroup analysis, genotype frequencies between UC patients with early onset of disease and controls showed significant difference for combined positions 2677 and 3435 (chi(2) = 16.054, df = 8, p = 0.034 for age at diagnosis >or=25, lower quartile). Herein the rare genotype 2677GG/3435TT was more frequently observed (odds ratio = 7.0, 95% confidence interval 2.5 - 19.7). In this group severe course of disease behaviour depended on the combined MDR1 SNPs (chi(2) = 16.101, df = 6, p = 0.017 for age at diagnosis >or=25). No association of MDR1 genotypes with disease subgroups in CD was observed. CONCLUSIONS While overall genotype distribution did not differ, combined MDR1 genotypes derived from positions 2677 and 3435 are possibly associated with young age onset of UC and severe course of disease in this patient group.

Abstract
Crohn disease (CD) is a chronic, relapsing inflammatory disorder of the gastrointestinal tract. Its etiology remained obscure until recently, when, through an overwhelming body of research, the main theme of its origin became clear. CD develops in individuals who carry risk alleles for the disease that can cause a loss of physiological tolerance to commensal bacteria. As a consequence, immune responses develop that activate a whole range of immunocompetent cells, resulting in the secretion of proinflammatory mediators that ultimately cause mucosal breaks and the formation of ulceration, edema, and loss of proper function.

Abstract
Genetic epidemiology, including twin studies, provides robust evidence that genetic variation in human populations contributes to susceptibility to infectious disease. One of the major limitations of studies that attempt to identify the genes and mechanisms that underlie this susceptibility has been lack of power caused by small sample size. With the development of novel technologies, burgeoning information on the human genome, the HapMap project, and human genetic diversity, we are at the beginning of a new era in the study of the genetics of complex diseases. This review looks afresh at the epidemiological evidence that supports a role for genetics in susceptibility to infectious disease, examines the somewhat limited achievements to date, and discusses current advances in methodology and technology that will potentially lead to translational data in the future.

Abstract
BACKGROUND AND AIMS The OCTN1 (SLC22A4 1672C-->T) and OCTN2 (SLC22A5 -207G-->C) variants within the IBD5 locus have been associated with susceptibility to adult onset Crohn's disease (CD), but their contribution in children has not been examined. METHODS These OCTN1/2 variants and IBD5 marker single nucleotide polymorphisms (SNPs) (IGR2096a_1, IGR2198a_1, and IGR2230a_1) were examined in 299 Scottish children (200 with CD, 74 with ulcerative colitis (UC), and 25 with indeterminate colitis (IC)), together with 502 parents (for transmission disequilibrium testing) and 256 controls. RESULTS All SNPs were in strong linkage disequilibrium (D' >0.94). TDT analysis showed association of the OCTN1 variant with inflammatory bowel disease (IBD) (p = 0.01) and CD (p = 0.04). Allele frequencies of the OCTN1/2 variants were significantly higher in IBD/CD cases (p<0.04). The homozygous mutant OCTN1/2 haplotype was increased in IBD (24.3% v 16.1%, p = 0.02) and UC (28.2% v 16.1%, p = 0.02) compared with controls. The OCTN1/2 variants were not independent of the background IBD5 risk haplotype in conferring disease susceptibility. Unifactorial analysis in CD patients showed that carriage of the TC haplotype was associated with lower weight, height, and BMI centile (<9(th) centile) at diagnosis (weight: 87.9% v 67.3% (p = 0.002), odds ratio (OR) = 3.52 (95% confidence interval, 1.51 to 8.22); height: 84.1% v 68.4% (p<0.05), OR = 2.44 (1.00 to 5.99); BMI: 79.6% v 61.1% (p = 0.02), OR = 2.49 (1.14 to 5.44)), and lower weight centile at follow up (87.5% v 64.6% (p = 0.03), OR = 3.83 (1.03 to 14.24)). Multifactorial binary logistic regression analysis confirmed association of the TC haplotype with lower weight centile at diagnosis (p = 0.02, OR = 3.41 (1.20 to 9.66)). CONCLUSIONS These data implicate variants within the IBD5 haplotype, as determinants of disease susceptibility and growth indices in early onset IBD. The OCTN1/2 variants remain potential positional candidate genes, but require further analysis.

Abstract
INTRODUCTION The incidence of early-onset CD in Scotland is among the highest worldwide. Three single nucleotide polymorphisms (SNPs) R702W, G908R and Leu1007finsC in the NOD2/CARD15 gene predispose to adult CD. We investigated the contribution of these variants to disease susceptibility and phenotype in the Scottish early-onset IBD population. PATIENTS AND METHODS 906 individuals including 247 Scottish IBD patients aged <16 years at diagnosis, 414 parents and 245 controls were genotyped. Transmission disequilibrium testing (TDT), case-control analysis and detailed genotype-phenotype analysis were performed. RESULTS The Leu1007finsC variant was associated with susceptibility to CD by case-control (4.2% versus. 1.4%, P = 0.01) and TDT analysis (P = 0.006). The Population Attributable Risk (PAR) for the 3 NOD2/CARD15 mutations was 7.9%. Carriage of NOD2/CARD15 variants was associated with, at diagnosis: decreased albumin (31.0% versus. 9.0%, P = 0.001) and raised CRP (25% versus. 9.5%, P = 0.04) and at follow up: need for surgery (39.5% versus. 12.8%, P = 0.0002) jejunal involvement (50% versus. 18.4%, P = 0.01) jejunal and ileal involvement (50% versus. 10.7%, P = 0.009), raised CRP (57.1% and 12.8%, P = 0.0009), lower weight/height centile (75.0% versus. 20.2%, P = 0.03, 50.0% versus. 16.0%, P = 0.001 respectively) and stricturing disease (45.5% versus. 19.4%, P < 0.05). Multifactorial analysis demonstrated carriage was associated with need for surgery (P = 0.004, OR 4.9 [1.5-14.7]). CONCLUSIONS These NOD2/CARD 15 variants in the Scottish early onset CD population have a definite, albeit relatively small contribution to CD susceptibility (PAR 7.9%) but a major impact on phenotype. In particular NOD2/CARD15 variants are strongly associated with several markers of disease severity in pediatric CD, notably need for surgery.

Abstract
The dystrobrevin-binding protein 1 (DTNBP1) gene on chromosome 6p has emerged as a potential susceptibility gene for schizophrenia. Although a number of attempts to replicate the original association finding have been successful, they have not identified any obvious pathogenic variants or a single at risk haplotype common to all populations studied. In the present study we attempted further replication in an independent sample of 638 nuclear families from the Han Chinese population of Sichuan Province, SW China. We also examined 580 Scottish schizophrenic cases and 620 controls. We genotyped 10 single-nucleotide polymorphisms (SNPs) in DTNBP1 that were used in the original report of association, plus rs2619538 (SNP 'A') in the putative promoter region, which has also been associated with schizophrenia. In the Chinese trios we found that two SNPs (P1635 and P1765) were significantly overtransmitted, but with alleles opposite to those reported in the original studies. SNPs P1757 and P1765 formed a common haplotype, which also showed significant overtransmission. In the Scottish cases and controls, no individual markers were significantly associated with schizophrenia. A single haplotype, which included rs2619538 and P1583, and one rare haplotype, composed of P1320 and P1757, were significantly associated with schizophrenia, but no previously reported haplotypes were associated. Based on the data from the Chinese population, our results provide statistical support for DTNBP1 as a susceptibility gene for schizophrenia, albeit with haplotypes different from those of the original study. However, our lack of replication in the Scottish samples also indicates that caution is warranted when evaluating the robustness of the evidence for DTNBP1 as genetic risk factor for schizophrenia.
