Abstract
PURPOSE There is currently no curative treatment for childhood Crohn's disease (CD). This meta-analysis aimed to validate the efficacy and safety of adalimumab (ADA) in pediatric patients with CD. MATERIALS AND METHODS We searched all relevant studies in the PubMed, Web of Science, Embase, and Cochrane Library databases. The primary outcomes were induction (≤ 12 weeks) and maintenance (up to 48 weeks) of remission and response. Secondary outcomes were severe adverse events and opportunistic infections to ADA. The Cochrane bias assessment tool was used to assess the risk of bias in randomized controlled trials. The methodological quality of the single-arm studies was assessed using the methodological index for non-randomized studies tool. RESULTS Ten clinical trials involving a total of 885 patients were included. Results indicated that 59% (95% confidence interval [CI] 39-80%) of the subjects treated with ADA achieved induction of remission, and 60% (95% CI 35-86%) of the subjects treated with ADA achieved induction of response, 57% (95% CI 44-70%) achieved maintenance of remission, and 63% (95% CI 26-69%) achieved maintenance of response. CONCLUSION Current evidence indicates that ADA is effective in children and adolescents with CD and that adverse events vary but are usually not severe.

Abstract
OBJECTIVES Infliximab is considered superior to adalimumab in patients with ulcerative colitis, especially in severe cases. Whether this is true for Crohn disease (CD) patients with colonic involvement is unclear. Our aim was to compare the clinical effectiveness of infliximab versus adalimumab in pediatric ileocolonic (L3) CD. METHODS This retrospective study included patients <18 years with ileocolonic CD treated with infliximab or adalimumab between 2014 and 2021. Primary outcome was steroid-free clinical remission by week 52. Secondary outcomes were treatment modifications, drug discontinuation, inflammatory bowel disease (IBD)-associated hospitalizations, and surgery during the first year of treatment. RESULTS We identified 74 patients treated with adalimumab and 41 with infliximab, with comparable demographic features. Concomitant immunomodulator therapy at biologic initiation was significantly lower in the adalimumab group (28% vs 85%, P < 0.001). Rates of drug intensification were higher in the infliximab group at end of induction (EOI) and at 52 weeks (55% vs 32% and 88% vs 46%, P < 0.001). Given significant differences between initial median Pediatric Crohn Disease Activity Index scores (20.0 [interquartile range, IQR 15.0-27.5] vs 11.0 [IQR 7.5-20.0] for infliximab and adalimumab groups, respectively, P < 0.001), propensity score matching was performed. Following matching, the rate of patients in steroid-free clinical remission by EOI was significantly higher in the adalimumab group (93.8% vs 46.9%, P < 0.001), but comparable by 1 year. Moreover, inflammatory markers and fecal calprotectin values were also similar at these time points. Rates of drug discontinuation, IBD-associated admissions, and surgery were similar between groups. CONCLUSIONS In a retrospective study of patients with ileocolonic CD, adalimumab and infliximab had comparable outcomes by 52 weeks.

Abstract
The introduction of biological agents with strong anti-inflammatory action, such as antitumor necrosis factor (TNF) agents, has changed inflammatory bowel disease (IBD) treatment strategy and goals, and has contributed significantly to improve the long-term prognosis of patients. Moreover, several biological agents are being used or researched in pediatric populations. However, only two biological agents, infliximab (IFX) and adalimumab (ADL), are currently approved for children and adolescents. In pediatric IBD, there are limitations and burdens associated with facilitating mucosal healing (MH) when utilizing these two biological agents. ADL is effective in both naïve patients and those with previous experience with biologics. Beyond clinical remission, this drug is also effective for MH and histological remission. The use of therapeutic drug monitoring to further enhance the effectiveness of ADL treatment can be expected to reduce treatment failure of ADL and pave the way for appropriate treatment in the treat-to-target era. This review paper focuses on ADL, examine studies conducted in children, and determine the role this agent plays against pediatric inflammatory bowel disease.

Vaccines in Children with Inflammatory Bowel Disease: Brief Review. Vaccines (Basel) 2021; 9:vaccines9050487.

Abstract
Incidence of inflammatory bowel diseases (IBDs), including Crohn's disease (CD) and ulcerative colitis (UC), is increasing worldwide. Children with IBDs have a dysfunctional immune system and they are frequently treated with immunomodulating drugs and biological therapy, which significantly impair immune system functions and lead to an increased risk of infections. Vaccines are essential to prevent at least part of these infections and this explains why strict compliance to the immunization guidelines specifically prepared for IBD patients is strongly recommended. However, several factors might lead to insufficient immunization. In this paper, present knowledge on the use of vaccines in children with IBDs is discussed. Literature review showed that despite a lack of detailed quantification of the risk of infections in children with IBDs, these children might have infections more frequently than age-matched healthy subjects, and at least in some cases, these infections might be even more severe. Fortunately, most of these infections could be prevented when recommended schedules of immunization are carefully followed. Vaccines given to children with IBDs generally have adequate immunogenicity and safety. Attention must be paid to live attenuated vaccines that can be administered only to children without or with mild immune system function impairment. Vaccination of their caregivers is also recommended. Unfortunately, compliance to these recommendations is generally low and multidisciplinary educational programs to improve vaccination coverage must be planned, in order to protect children with IBD from vaccine-preventable diseases.

Abstract
Paradoxical psoriasis (PP) may occur during treatment with anti-tumor necrosis factor-alpha (TNF-α) drugs in various chronic immune-mediated diseases, mainly inflammatory bowel diseases (IBD) and psoriasis. In this study, clinical and genetic characteristics of PP arising in IBD and psoriatic patients were investigated to identify disease-specific markers of the paradoxical effect. A total of 161 IBD and psoriatic patients treated with anti-TNF-α drugs were included in the study. Of these patients, 39 developed PP. All patients were characterized for the main clinical–pathologic characteristics and genotyped for six candidate single nucleotide polymorphisms (SNPs) selected for their possible role in PP susceptibility. In IBD patients, the onset of PP was associated with female sex, presence of comorbidities, and use of adalimumab. IBD patients with PP had a higher frequency of the TNF-α rs1799964 rare allele (p = 0.006) compared with cases without the paradoxical effect, and a lower frequency of the human leucocyte antigen (HLA)-Cw06 rs10484554 rare allele (p = 0.03) compared with psoriatic patients with PP. Overall, these findings point to specific clinical and genetic characteristics of IBD patients with PP and provide data showing that genetic variability may be related to the paradoxical effect of anti-TNF-α drugs with possible implications into clinical practice.

Abstract
Biological therapies, especially blocking tumor necrosis factor-α (TNFα) agents have radically changed the therapeutic approach and disease course of pediatric inflammatory bowel disease (IBD). In particular, drugs such as infliximab (IFX) and adalimumab (ADA) have been demonstrated to be effective in inducing and maintaining corticosteroid-free remission in both adult and pediatric patients with Crohns Disease (CD) and Ulcerative colitis (UC). Biosimilar biological (BioS) therapy is increasingly being used in pediatric age even though most knowledge on the safety and efficacy of these agents is based on IFX in adult IBD data. Studies show high rates of clinical response and remission in both IFX naïve patients and in patients switched from originator to BioS with similar risks of adverse events (AEs) as those reported with IFX originator. In the present review indications, efficacy and AEs of biological therapy in pediatric IBD will be discussed, as well as the role of other biological agents such as Golimumab, Vedolizumab and Ustekinumab, the role of BioS biological therapy and utility of therapeutic drug monitoring in clinical practice.

Abstract
BACKGROUND AND AIMS Epidemiological studies have established an association between psoriasis and inflammatory bowel disease [IBD], i.e. ulcerative colitis [UC] and Crohn's disease [CD], but results are inconsistent. The aim of this study was therefore to quantify the prevalences and association between IBD and psoriasis. METHODS PubMed, Web of Science, and EMBASE were searched from database inception through April 2018 for studies reporting data on psoriasis among patients with IBD and vice versa. Meta-analysis was performed to estimate, respectively, the prevalences and association between IBD and psoriasis. Data extraction was according to the PRISMA guideline, and quality assessment was made using the Newcastle-Ottawa Scale. The main outcomes were the proportion of psoriasis patients with IBD and vice versa, as well as the association (odds ratio [OR]) of IBD in psoriasis and psoriasis in IBD, respectively. RESULTS Based on quantitative analysis of 93 studies, the prevalence of psoriasis in CD and in UC was 3.6% (95% confidence interval [CI] 3.1%-4.6%) and 2.8% [95% CI 2.0%-3.8%] respectively. The prevalence of CD and UC was 0.7% [95% CI 0.2%-1.3%] and 0.5% [95% CI 0.3%-0.8%], respectively, among patients with psoriasis. Presence of CD or UC was significantly associated with psoriasis, with OR 2.0 [95% CI 1.4-2.9] and OR 1.5 [95% CI 1.2-2.0], respectively. Presence of psoriasis was significantly associated with CD: OR 2.2 [95% CI 1.6-3.1] and with UC: OR 1.6 [95% CI 1.3-2.0]. CONCLUSIONS We found significant bidirectional associations between psoriasis and IBD, warranting increased awareness among clinicians in the diagnostic process, especially in children and adolescents with IBD. Last, this study showed an increased frequency of paradoxical psoriasis in patients treated with biologics.

Abstract
Introduction: Anti-Tumor Necrosis Factor-alpha (TNF-α) therapy, primarily infliximab and adalimumab, are now increasingly used to induce and maintain disease remission in the pediatric perianal Crohn's disease (CD) population, however, their optimal use has not yet been defined in the pediatric setting.Areas covered: In accordance with a published protocol (PROSPERO no. CRD42019118838), we systematically and critically evaluated all published evidence on the efficacy and safety of anti-TNF-α in children with perianal CD, in the PubMed, MEDLINE, Embase, Cochrane and clinicalTrials.gov databases until October, 18th, 2018. We included in our systematic review 29 articles yielding a total of 565 perianal CD patients aged between 9 months to 18 years.Expert opinion: According to low-quality evidence from small, uncontrolled and heterogeneous descriptive studies, and very few randomized controlled trial, nearly three-fifths children with perianal CD achieved remission with anti-TNF-α treatment and in approximately 40% remission was maintained after 12 months, with practically low discontinuation rate due to serious adverse events. More than half of the patients achieved complete fistula closure. There is still a need for more robust evidence adequately assessing the efficacy and safety of anti-TNF-α therapy in pediatric perianal CD, as well as in comparison with other therapies.

Abstract
BACKGROUND/OBJECTIVES The development of psoriasis while on tumor necrosis factor inhibitors (TNFi) is a paradoxical effect of agents that treat psoriasis. There is a paucity of data available on this entity in juvenile idiopathic arthritis (JIA). Our objectives were to determine the prevalence of TNFi-induced psoriasis in patients with JIA at two pediatric centers, and psoriasis response to therapeutic modifications. METHODS We performed retrospective chart review on patients with JIA treated with TNFi (adalimumab, etanercept, infliximab) who developed psoriasis. TNFi-induced psoriasis was defined as an incident diagnosis of psoriasis after starting a TNFi. Patients with personal histories of psoriasis prior to TNFi therapy were excluded. Following diagnosis, responses to medication changes were defined based on physician assessments. RESULTS Nine of 166 (5.4%) patients on TNFi for JIA were diagnosed with TNFi-induced psoriasis. All cases were female. One had a family history of psoriasis. The median age was 10 (range 2-16) years. Five (55%) patients experienced scalp psoriasis, including four (44%) with alopecia. Two (22%) patients achieved significant improvement after switching to different classes of biologic agents, while three (33%) patients had significant improvement following discontinuation of biologic therapy. One of five patients who switched to a different TNFi had complete resolution, while four had worsening symptoms or partial improvement. CONCLUSIONS Our findings demonstrate the prevalence of TNFi-induced psoriasis in JIA at two centers. Though larger studies are needed, our data suggest discontinuation of TNFi or biologic class switching should be considered as treatment strategies in select patients.

Abstract
Autism spectrum disorders (ASD) and inflammatory bowel disease (IBD) both have multifactorial pathogenesis with an increasing number of studies demonstrating gut-brain associations. We aim to examine the association between ASD and IBD using strict classification criteria for IBD. We conducted a retrospective case-cohort study using records from the Military Health System database with IBD defined as having one encounter with an ICD-9-CM diagnostic code for IBD and at least one outpatient prescription dispensed for a medication to treat IBD. Children with ASD were more likely to meet criteria for Crohn's disease (CD) and Ulcerative colitis (UC) compared to controls. This higher prevalence of CD and UC in children with ASD compared to controls confirms the association of ASD with IBD.

Abstract
Background Adalimumab (Ada) treatment is an available option for pediatric Crohn’s disease (CD) and the published experience as rescue therapy is limited. Objectives We investigated Ada efficacy in a retrospective, pediatric CD cohort who had failed previous infliximab treatment, with a minimum follow-up of 6 months. Methods In this multicenter study, data on demographics, clinical activity, growth, laboratory values (CRP) and adverse events were collected from CD patients during follow-up. Clinical remission (CR) and response were defined with Pediatric CD Activity Index (PCDAI) score ≤10 and a decrease in PCDAI score of ≥12.5 from baseline, respectively. Results A total of 44 patients were consecutively recruited (mean age 14.8 years): 34 of 44 (77%) had active disease (mean PCDAI score 24.5) at the time of Ada administration, with a mean disease duration of 3.4 (range 0.3–11.2) years. At 6, 12, and 18 months, out of the total of the enrolled population, CR rates were 55%, 78%, and 52%, respectively, with a significant decrease in PCDAI scores (P<0.01) and mean CRP values (mean CRP 5.7 and 2.4 mL/dL, respectively; P<0.01) at the end of follow-up. Steroid-free remission rates, considered as the total number of patients in CR who were not using steroids at the end of this study, were 93%, 95%, and 96% in 44 patients at 6, 12, and 18 months, respectively. No significant differences in growth parameters were detected. In univariate analysis of variables related to Ada efficacy, we found that only a disease duration >2 years was negatively correlated with final PCDAI score (P<0.01). Two serious adverse events were recorded: 1 meningitis and 1 medulloblastoma. Conclusion Our data confirm Ada efficacy in pediatric patients as second-line biological therapy after infliximab failure. Longer-term prospective data are warranted to define general effectiveness and safety in pediatric CD patients.

Abstract
BACKGROUND Therapeutic drug monitoring (TDM) in inflammatory bowel disease (IBD) patients receiving anti-tumour necrosis factor (TNF) agents can help optimise outcomes. Consensus statements based on current evidence will help the development of treatment guidelines. AIM To develop evidence-based consensus statements for TDM-guided anti-TNF therapy in IBD. METHODS A committee of 25 Australian and international experts was assembled. The initial draft statements were produced following a systematic literature search. A modified Delphi technique was used with 3 iterations. Statements were modified according to anonymous voting and feedback at each iteration. Statements with 80% agreement without or with minor reservation were accepted. RESULTS 22/24 statements met criteria for consensus. For anti-TNF agents, TDM should be performed upon treatment failure, following successful induction, when contemplating a drug holiday and periodically in clinical remission only when results would change management. To achieve clinical remission in luminal IBD, infliximab and adalimumab trough concentrations in the range of 3-8 and 5-12 μg/mL, respectively, were deemed appropriate. The range may differ for different disease phenotypes or treatment endpoints-such as fistulising disease or to achieve mucosal healing. In treatment failure, TDM may identify mechanisms to guide subsequent decision-making. In stable clinical response, TDM-guided dosing may avoid future relapse. Data indicate drug-tolerant anti-drug antibody assays do not offer an advantage over drug-sensitive assays. Further data are required prior to recommending TDM for non-anti-TNF biological agents. CONCLUSION Consensus statements support the role of TDM in optimising anti-TNF agents to treat IBD, especially in situations of treatment failure.

Abstract
BACKGROUND Little is known about changes in the imaging appearances of the bowel and mesentery over time in either pediatric or adult patients with newly diagnosed small bowel Crohn disease treated with anti-tumor necrosis factor-alpha (anti-TNF-α) therapy. OBJECTIVE To define how bowel ultrasound findings change over time and correlate with laboratory inflammatory markers in children who have been newly diagnosed with pediatric small bowel Crohn disease and treated with infliximab. MATERIALS AND METHODS We included 28 pediatric patients treated with infliximab for newly diagnosed ileal Crohn disease who underwent bowel sonography prior to medical therapy and at approximately 2 weeks, 1 month, 3 months and 6 months after treatment initiation; these patients also had laboratory testing at baseline, 1 month and 6 months. We used linear mixed models to compare mean results between visits and evaluate whether ultrasound measurements changed over time. We used Spearman rank correlation to assess bivariate relationships. RESULTS Mean subject age was 15.3±2.2 years; 11 subjects were girls (39%). We observed decreases in mean length of disease involvement (12.0±5.4 vs. 9.1±5.3 cm, P=0.02), maximum bowel wall thickness (5.6±1.8 vs. 4.7±1.7 mm, P=0.02), bowel wall color Doppler signal (1.7±0.9 vs. 1.2±0.8, P=0.002) and mesenteric color Doppler signal (1.1±0.9 vs. 0.6±0.6, P=0.005) at approximately 2 weeks following the initiation of infliximab compared to baseline. All laboratory inflammatory markers decreased at 1 month (P-values<0.0001). There was strong correlation between bowel wall color Doppler signal and fecal calprotectin (ρ=0.710; P<0.0001). Linear mixed models confirmed that maximum bowel wall thickness (P=0.04), length of disease involvement (P=0.0002) and bowel wall color Doppler signal (P<0.0001) change over time in response to infliximab, when adjusted for age, sex, azathioprine therapy, scanning radiologist and baseline short pediatric Crohn's disease activity index score. CONCLUSION The ultrasound appearance of the bowel changes as early as 2 weeks after the initiation of infliximab therapy. There is strong correlation between bowel wall color Doppler signal and fecal calprotectin.

Abstract
INTRODUCTION Anti-TNFα therapy has revolutionised treatment of inflammatory bowel disease, however primary non-response and secondary loss of response are a significant problem. Therapeutic drug monitoring (TDM) has recently emerged as a means of optimising use of anti-TNFα agents. Areas covered: TDM of anti-TNFα agents can guide clinical decisions during treatment failure events, prevent treatment failure events, and potentially result in significant healthcare cost saving. TDM for anti-TNFα agent involves measurement of drug levels and anti-drug antibodies, and can be performed reactively or proactively. Reactive TDM reserves testing for treatment failure events, while proactive TDM also consists of periodic TDM for patients responding to anti-TNFα therapy to allow treatment optimisation. Generation of anti-drug antibodies is recognised as one important mechanism of treatment failure and adverse events. Expert opinion: Evidence strongly supports TDM at time of treatment failure, while studies employing proactive TDM have demonstrated conflicting results. TDM can also help better select patients likely to remain in clinical remission on anti-TNFα treatment interruption. Currently TDM is used to optimise anti-TNFα treatment, but it is not used by most clinicians to prevent adverse reactions to anti-TNFα agents.

Abstract
BACKGROUND AND AIM Adalimumab is well-established therapy for adults with Crohn's disease [CD]. The aim of the study was to systematically assess the published evidence on the efficacy and safety of adalimumab for Crohn's disease in children. METHODS MEDLINE, EMBASE, the Cochrane Library, and abstracts from the main gastroenterological meetings in the past 5 years were systematically searched up to July 2015 for randomised controlled trials and observational studies on the efficacy and safety of adalimumab for Crohn's treatment in children and adolescents. RESULTS A total of 14 studies [1 randomised controlled trial, 13 case series], altogether including 664 patients [age: 1.9 to 21 years] were available for analysis. The studies differed with respect to patients' characteristics, including percentage of infliximab-naïve patients, disease duration, site of the disease, adalimumab doses, treatment duration, and follow-up period. The pooled remission rates were: 30% [n = 93/309] at 4 weeks, 54% [n = 79/145] at 3 months, 45% [n = 18/40] at 4 months, 42% [n = 146/345] at 6 months, 57% [n = 20/35] at 8 months, and 44% [n = 169/383] at 12 months. Of the total patients, 6% [n = 13/207] were classified as primary non-responders and 12% [n = 69/599] had severe adverse events reported including 2 deaths and 1 medulloblastoma. Withdrawal rate due to adverse events reported in one study was 35% [n = 64/182]. CONCLUSION According to low-quality evidence based mainly on case series, approximately half of children with Crohn's disease on adalimumab therapy achieve remission during the first year of the therapy with reasonable safety profile. There is still a need for high-quality evidence on effectiveness and safety of adalimumab for paediatric Crohn's disease.

Abstract
BACKGROUND Nonresponse and loss of response to anti-TNF therapies in Crohn's disease represent significant clinical problems for which clear management guidelines are lacking. AIM To review the incidence, mechanisms and predictors of primary nonresponse and secondary loss of response to formulate practical clinical algorithms to guide management. METHODS Through a systematic literature review, 503 articles were identified which fit the inclusion criteria. RESULTS Primary nonresponse to anti-TNF treatment affects 13-40% of patients. Secondary loss of response to anti-TNF occurs in 23-46% of patients when determined according to dose intensification, and 5-13% of patients when gauged by drug discontinuation rates. Recent evidence suggests that the mechanisms underlying primary nonresponse and secondary loss of response are multifactorial and include disease characteristics (phenotype, location, severity); drug (pharmacokinetic, pharmacodynamic or immunogenicity) and treatment strategy (dosing regimen) related factors. Clinical algorithms that employ therapeutic drug monitoring (using anti-TNF tough levels and anti-drug antibody levels) may be used to determine the underlying cause of primary nonresponse and secondary loss of response respectively and guide clinicians as to which patients are most likely to respond to anti-TNF therapy and help optimise drug therapy for those who are losing response to anti-TNF therapy. CONCLUSIONS Nonresponse or loss of response to anti-TNF occurs commonly in Crohn's disease. Clinical algorithms utilising therapeutic drug monitoring may establish the mechanisms for treatment failure and help guide the subsequent therapeutic approach.

Abstract
BACKGROUND AND AIMS There is growing evidence that in Crohn's disease the achievement and maintenance of mucosal healing (MH) through anti-TNFα antibodies may change the natural history of the disease. Few studies evaluating such outcome as a therapeutic goal are available in paediatrics. The primary aim of the study was to assess the efficacy of biologics in obtaining MH in a paediatric Crohn's disease cohort. The secondary aims were: (1) to assess response based on early or late treatment introduction and on combination therapy with immunomodulators versus biologics alone; and (2) to evaluate clinical outcome 2 years after the second endoscopy. METHODS Biologic-naive paediatric Crohn's disease patients starting anti-tumour necrosis factor α (TNFα) treatment were enrolled. Patients' demographic and treatment data were recorded. Clinical [Pediatric Crohn's Disease Activity Index (PCDAI)] and endoscopic [Simple Endoscopic Score for Crohn's Disease (SES-CD)] evaluations were performed at time 0 (T0) and after 9-12 months (follow-up). Appropriate induction and maintenance therapeutic schemes were applied. RESULTS Thirty-seven patients were enrolled. At enrolment, mean age was 12.3 ± 3.4 years and mean disease duration was 13.0 ± 16 months. At follow-up there was a significant decrease in PCDAI and SES-CD compared with T0 (p < 0.01). No statistical difference in frequency of MH between the early and late treatment introduction groups was found. Combination therapy was superior in obtaining complete plus partial MH (p < 0.01). One and 2 years after the second endoscopy, all and 79% of patients with complete MH and 75 and 67% of those with partial MH were still in clinical remission, respectively. CONCLUSIONS Biologics improve mucosal lesions, apparently more effectively if given in combination with immunomodulators. MH appears to sustain a better disease course.

Abstract
AIM: To study whether adalimumab (ADA) was associated with improvement in growth, bone mineral density (BMD) and bone metabolism.
METHODS: In children with Crohn’s disease (CD) there is a high prevalence of growth failure and reduced BMD. Treatment with infliximab is associated with an improvement in growth. Anthropometry, paediatric CD activity index (PCDAI), bone markers and BMD was measured in 18 patients (72% females) one year before and after start of ADA with a median age of 14.4 years (range: 5-19 years) at treatment start. Outcomes were indicators of growth with treatment as well as interval growth.
RESULTS: Eleven (61%) children experienced catch-up growth after ADA. PCDAI significantly decreased from 52.1 ± 16 to 30.4 ± 23 (P≤ 0.001). Post ADA, body mass index (BMI) standard deviation score (SDS) 0.1[range: 2.7-(-0.8)] vs -1 [range: 0.1-(-3.6)], P = 0.04 and ∆BMI SDS in children 0.3 [range: 0.7-(-0.2)] vs -1.1 [range: 1.2-(-2.3)], P = 0.01 in remission were significantly higher compared to those with moderate to severe inflammation. The main predictors for growth were 25-hydroxycholecalciferol and for bone mineralisation weight and height SDS. ADA had no significant influence on bone markers and BMD.
CONCLUSION: Next to improvement of PCDAI, half of the children achieved a positive catch-up growth. A better nutritional status with improvement in BMI and weight is positive predictor for improved growth and bone mineralisation.

Abstract
The efficacy and safety of biologic response modifiers such as etanercept, adalimumab, infliximab, and ustekinumab have been demonstrated in the treatment of psoriasis in adults, but none are currently approved for the treatment of psoriasis in children in the United States, and only etanercept is approved for the treatment of psoriasis in children in the European Union. Through case reports, case series, and a large clinical trial of the use of etanercept, the literature supports the use of these agents to treat psoriasis in children. Data on the use of the tumor necrosis factor-α antagonists etanercept, adalimumab, and infliximab in the treatment of other inflammatory diseases in children-namely Crohn's disease, juvenile arthritis, and uveitis--support their safety profile in children.

Abstract
Adalimumab is a fully humanized anti-tumor necrosis factor alpha monoclonal antibody that was recently granted regulatory approval in the USA for the treatment of moderate to severe Crohn’s disease (CD) in children. Like infliximab, the first biologic agent used to treat pediatric CD, regulatory approval was secured many years following approval for adults. The long delay between adult and pediatric approval has led to many years of off-label use of adalimumab, although it is anticipated that the use of adalimumab may further increase with official regulatory approval. To date, pediatric literature on the use of adalimumab for treatment of CD is limited, and pediatric practitioners have mostly extrapolated from research and experience provided by the adult literature. The aim of this paper is to review the literature regarding adalimumab for the treatment of pediatric CD, and includes a review of landmark adult studies as well as the pivotal pediatric study that facilitated regulatory approval. We also discuss the role of anti-tumor necrosis factor alpha agents including adalimumab in the current treatment paradigm for pediatric CD.

Abstract
A young patient with Crohn's disease is presented in whom pulmonary carcinoid tumor was incidentally found. Bronchoscopy showed an endobronchial lesion and biopsy pathology was consistent with atypical carcinoid. Octeotride scan suggested primary origin of the tumor. Although patients with Crohn's disease have been reported to have increased incidence of intestinal carcinoid, we believe this to be the second case of primary carcinoid pulmonary located in this population.

Abstract
The development of biological agents with specific immunological targets has revolutionized the treatment of a wide variety of paediatric diseases where traditional immunosuppressive agents have been partly ineffective or intolerable. The increasing requirement for pharmaceutical companies to undertake paediatric studies has provided impetus for studies of biologics in children. The assessment of biological agents in children to date has largely relied upon randomized controlled trials using a withdrawal design, rather than a parallel study design. This approach has been largely used due to ethical concerns, including use of placebo treatments in children with active chronic disease, and justified on the basis that treatments have usually already undergone robust assessment in related adult conditions. However, this study design limits the reliability of the data and can confuse the interpretation of safety results. Careful ongoing monitoring of safety and efficacy in real-world practice through national and international biologics registries and robust reporting systems is crucial. The most commonly used biological agents in children target tumour necrosis factor-α, interleukin-1, interleukin-6 and cytotoxic lymphocyte-associated antigen-4. These agents are most frequently used in paediatric rheumatic diseases. This review discusses the development and assessment of biologics within paediatric rheumatology with reference to the lessons learned from use in other subspecialties.

[PMID: 24462626 DOI: 10.1016/j.cgh.2014.01.021] [Citation(s) in RCA: 102] [Impact Index Per Article: 10.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2013] [Revised: 12/27/2013] [Accepted: 01/08/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Many physicians hesitate to recommend anti-tumor necrosis factor (TNF) therapy for pediatric patients with inflammatory bowel disease (IBD) because of concerns about risk of infection and cancer. We performed a systematic review to quantify the incidence of serious infection, lymphoma, and death among pediatric patients with IBD who received anti-TNF therapy. These values were compared with those expected from other treatments, from adults with IBD, and from the general pediatric population. METHODS We searched MEDLINE, EMBASE, the Cochrane Collaboration, and Web of Knowledge for studies of infliximab therapy for children with ulcerative colitis or Crohn's disease, or adalimumab therapy for children with Crohn's disease. Standardized incidence ratios (SIRs) were calculated, comparing rates of infection and cancer among pediatric patients exposed to anti-TNF agents vs expected rates from pediatric patients not exposed to anti-TNF therapies or adult patients exposed to anti-TNF agents. Our analysis included 5528 patients with 9516 patient-years of follow-up evaluation (PYF). RESULTS The rate of serious infections among pediatric patients treated with anti-TNF agents (352/10,000 PYF) was similar to that of pediatric patients who received immunomodulator monotherapy (333/10,000 PYF; SIR, 1.06; 95% confidence interval [CI], 0.83-1.36), but significantly lower than the expected rate for pediatric patients treated with steroids (730/10,000 PYF; SIR, 0.48; 95% CI, 0.40-0.58) or adults treated with anti-TNF agents (654/10,000 PYF; SIR, 0.54; 95% CI, 0.43-0.67). Five treatment-related deaths occurred (4 from sepsis and 1 from arrhythmia). Two patients developed lymphoma (2.1/10,000 PYF). This value was similar to the expected rate of lymphoid neoplasia in the entire pediatric population (5.8/100,000 PYF; SIR, 3.5; 95% CI, 0.35-19.6), and lower than the population of pediatric patients receiving thiopurine monotherapy (4.5/10,000 PYF; SIR, 0.47; 95% CI, 0.03-6.44), and among adults treated with anti-TNF agents (6.1/10,000 PYF; SIR, 0.34; 95% CI, 0.04-1.51). CONCLUSIONS Based on a systematic review, the risk of lymphoma was no greater among children with IBD who received anti-TNF therapy than those treated with other IBD therapies or adults treated with anti-TNF agents. The rate of serious infection was significantly lower among pediatric patients with IBD treated with anti-TNF agents than those treated with steroids, or adults with IBD who received anti-TNF therapy.

Abstract
Tumour necrosis factor (TNF) plays an important role in the pathogenesis of immune-mediated inflammatory diseases (IMIDs). TNF inhibition results in down-regulation of abnormal and progressive inflammatory processes, resulting in rapid and sustained clinical remission, improved quality of life and prevention of target organ damage. Adalimumab is the first fully human monoclonal antibody directed against TNF. In this article, we review the role and cost effectiveness of adalimumab in the treatment of IMIDs in adults and children. The efficacy and tolerability of adalimumab has been demonstrated in patients with a wide range of inflammatory conditions, leading to regulatory approval in rheumatoid arthritis (RA), psoriatic arthritis (PsA), plaque psoriasis, inflammatory bowel diseases (Crohn's disease, ulcerative colitis, paediatric Crohn's disease, and intestinal Behçet's disease), ankylosing spondylitis (AS), axial spondyloarthritis (SpA) and juvenile idiopathic arthritis. The major tolerability issues with adalimumab are class effects, such as injection site reactions and increased risk of infection and lymphoma. As with all anti-TNF agents, adalimumab is immunogenic, although less than infliximab, and some patients receiving long-term adalimumab will develop anti-drug antibodies, causing a loss of response. Comparisons of its clinical utility and cost effectiveness have shown it to be a valid treatment choice in a wide range of patients. Recent data from Italian economic studies show the cost effectiveness of adalimumab to be below the threshold value for health care interventions for most indications. In addition, analysis of indirect costs shows that adalimumab significantly reduces social costs associated with RA, PsA, AS, Crohn's disease and psoriasis. The fact that adalimumab has the widest range of approved indications, many often presenting together in the same patient due to the common pathogenesis, may further improve the utility of adalimumab. Current clinical evidence shows adalimumab to be a valuable resource in the management of IMIDs. Further research, designed to identify patients who may benefit most from this drug, will better highlight the role and cost-effectiveness of this versatile TNF inhibitor.

Abstract
OBJECTIVE The antitumor necrosis factor α (TNFα) antibodies infliximab and adalimumab are effective in inducing and maintaining remission in pediatric patients with Crohn disease (CD). The aim of the study was to evaluate the long-term efficacy and safety of biological therapy in pediatric patients with CD followed at a referral center. METHODS This work is a retrospective observational study enrolling patients with CD treated with infliximab or adalimumab beyond the induction protocol. The patients' data were collected from the unit's IBD database (maximum follow-up evaluation after 36 months of treatment). The efficacy was evaluated by the Pediatric Crohn Disease Activity Index score and by analysis of the cumulative probability of continuing therapy; the safety was assessed in terms of adverse events. RESULTS We enrolled 78 patients; the mean therapy duration was 27.2 ± 16.7 months, and the mean age at enrollment was 15 ± 3.1 years. The Kaplan-Meier analysis showed a cumulative probability of continuing therapy of 81%, 54%, and 33% at 1, 2, and 3 years, respectively, from the introduction of therapy. No association between the patients' baseline characteristics and the long-term outcome was found. The evaluation of the concomitant therapy with immunomodulators and anti-TNFα therapy versus anti-TNFα alone did not show a different outcome. No serious adverse events were recorded. CONCLUSIONS The study indicates that biological therapy is effective and safe in pediatric patients with CD in a longer follow-up period. The response to treatment was not influenced by the patients' baseline characteristics or by the immunomodulator association.

Abstract
IBD includes two classic entities, Crohn's disease and ulcerative colitis, and a third undetermined form (IBD-U), characterized by a chronic relapsing course resulting in a high rate of morbidity and impaired quality of life. Children with IBD are vulnerable in terms of growth failure, malnutrition and emotional effects. The aims of therapy have now transitioned from symptomatic control to the achievement of mucosal healing and deep remission. This type of therapy has been made possible by the advent of disease-modifying drugs, such as biologic agents, which are capable of interrupting the inflammatory cascade underlying IBD. Biologic agents are generally administered in patients who are refractory to conventional therapies. However, there is growing support that such agents could be used in the initial phases of the disease, typically in paediatric patients, to interrupt and cease the inflammatory process. Until several years ago, most therapeutic programmes in paediatric patients with IBD were borrowed from adult trials, whereas paediatric studies were often retrospective and uncontrolled. However, guidelines on therapeutic management of paediatric IBD and controlled, prospective, randomized trials including children with IBD have now been published. Here, the current knowledge concerning treatment options for children with IBD are reported. We also highlight the effectiveness and safety of new therapeutic advances in these paediatric patients.

Abstract
: Anti-tumor necrosis factor agents are now considered to be a vital component of the treatment algorithm for pediatric inflammatory bowel disease. Despite the clear benefit of these agents and the realignment of treatment goals to achieve early mucosal healing, the decision to initiate therapy is often delayed due to uncertainties regarding risks and benefits. The purpose of this review was to summarize the currently available data regarding anti-tumor necrosis factor agents in pediatric inflammatory bowel disease. Specifically, we review their expected efficacy in both Crohn's disease and ulcerative colitis and the likelihood of side effects associated with these agents. In addition, we address the barriers physicians face when communicating these data and help to identify how pediatric patients and their parents can be more involved in a shared decision-making process. Through the creation of a new decision aid (Option Grid), we hope to allow for a more clear line of communication at the bedside when helping patients and parents make these difficult treatment decisions.

Abstract
Tumor necrosis factor alpha (TNF-α) inhibitors are increasingly administered to children and adolescents with juvenile idiopathic arthritis (JIA) and pediatric inflammatory bowel disease (pIBD). Adult studies indicate that TNF-α inhibitors lead to an increased risk of serious infections compared to other disease-modifying antirheumatic drugs. We report herein a systematic literature review detailing the epidemiology and types of infections reported in children with JIA and pIBD treated with TNF-α inhibitors. The most frequently reported infections were mild and characterized as viral in etiology. Severe bacterial and fungal infections also occurred, but were less common and possibly associated with intrinsic risk factors and concurrent immunosuppressive therapy. Few pediatric patients developed Mycobacterium tuberculosis, likely due to effective screening. There were 8 infectious fatalities in children treated with TNF-α inhibitors. Overall, although rare, serious infections occur in immunocompromised children and adolescents with JIA and pIBD receiving TNF-α inhibitors.

Abstract
BACKGROUND Anti tumor necrosis factor alpha (TNFα) agents have become widely used in pediatric inflammatory bowel disease (IBD). So far, only few studies examined the long-term results of anti-TNFα treatment in children with IBD. METHODS The long-term outcome of pediatric patients with IBD was assessed retrospectively in a multicenter cohort of children treated with anti-TNFα beyond induction treatment. Short- and long-term response rates, predictors for loss of response, data on growth and laboratory parameters were assessed. RESULTS 120 patients [101 crohn's disease (CD), 19 ulcerative colitis (UC) or indeterminate colitis (IC)] received either infliximab or adalimumab. The mean age at initiation of anti-TNFα was 13.4 ± 3.9 years and the median duration of anti-TNFα treatment was 15 months (range: 2-90). Overall, 89% of the cohort experienced short-term response following induction. Response was associated with improvement in weight and BMI Z-scores (p<0.001) but not with linear growth. Responders experienced a significant decrease in erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) during treatment (p<0.001). Albumin and hemoglobin both improved but only albumin increased significantly (p<0.001). The cumulative probability of losing response to anti-TNFα treatment was 17%, 38%, and 49% after 1, 3, and 5 years, respectively. Responders had a significantly lower weight and BMI Z-scores at initiation of anti-TNFα treatment in compared to non-responders (p=0.04 and 0.02 respectively). CONCLUSIONS Our long term cohort supports the current evidence on the effectiveness and safety of anti-TNFα treatment in children with IBD. Response to treatment was interestingly associated with lower weight and BMI.

Abstract
BACKGROUND Infliximab (IFX), an established therapy for pediatric Crohn disease (CD), is also efficacious in treating psoriasis, a skin disorder, in which tumor necrosis factor-α is implicated pathogenically. Paradoxically, there have been numerous reports of new-onset psoriasis following tumor necrosis factor-α antagonist therapy in adult patients with inflammatory bowel disease, but pediatric data are sparse. METHODS A retrospective review of all IFX-treated patients with CD, who subsequently developed psoriasis, at a single pediatric inflammatory bowel disease center, was performed. A subset of affected patients (10/18) and CD controls (147 of 172) treated with IFX but without the development of psoriasis were genotyped for polymorphisms in the interleukin-23 receptor (IL-23R) gene, which has been identified as conferring susceptibility to both CD and psoriasis. RESULTS Eighteen (10.5%) of 172 IFX-treated patients with CD developed new-onset psoriasis (n = 17) or worsening of existing psoriasis (n = 1). The duration of IFX exposure was variable, ranging from 1 to 25 infusions. Three patients discontinued IFX because of this complication. Most patients responded well to topical steroid therapy. In comparison to disease-matched controls, patients with CD developing psoriasis following IFX therapy were more likely to be homozygous for specific polymorphisms in the IL-23R gene (rs10489628, rs10789229, and rs1343151). CONCLUSIONS As in adults, the development of psoriasis or psoriasiform skin lesions occurs in pediatric patients with CD treated with IFX. Adequately powered studies are required to further explore the preliminary findings reported here to determine whether polymorphisms in the IL-23R gene have a role in the pathogenesis of this paradoxical process, which presently remains unexplained.

Abstract
BACKGROUND AND OBJECTIVES Crohn disease (CD) is an increasingly recognized problem in Saudi Arabia. The aim of this study was to describe the clinical pattern in children and adolescents with CD seen at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. DESIGN AND SETTING Retrospective hospital-based study conducted on data collected for the period between January 2001 and March 2010. PATIENTS AND METHODS Data for all children and adolescents diagnosed at KAUH with CD in the period were retrieved and analyzed. RESULTS Ninety-six patients were identified. The median age at diagnosis was 11.3 years (range, 0.12-17.6 years). Fifty (52.1%) were males. Sixty-four (66.7%) were Saudis. Nine (9.4%) had a first degree relative with inflammatory bowel disease. The most common presenting symptoms were diarrhea (88.5%), weight loss (84.2%) and anorexia (80.2%). At least one extraintestinal manifestation occurred in 24% of patients. Forty-two percent were underweight and 19% had short stature. The most common distribution was ileocolonic (37.5%), followed by colonic in 31.2%. Twenty-five (26%) patients had perianal disease, 13 (13.5%) had strictures and 15 (15.6%) had penetrating disease. Laboratory investigations revealed anemia in 84.4%, thrombocytosis in 50%, hypoalbuminemia in 64.6%, elevated erythrocyte sedimentation rate (ESR) in 50% and elevated C-reactive protein in 58.3%. Induction of remission was achieved with enteral nutrition in 20% of patients and with corticosteroids in the remaining. CONCLUSIONS The clinical pattern of CD in children from the Western Province of Saudi Arabia was found to be similar to reports from the West. Pediatricians should be aware of the varying presentations of CD. Early referral to specialized centers is crucial.

Abstract
BACKGROUND With a prevalence of 0.71%, psoriasis represents one of the most frequent dermatoses in childhood. PATIENTS AND METHODS Eight children with severe psoriasis who failed to respond to other therapy received a weight- adapted treatment with etanercept (0.8 mg/kg body) administered subcutaneously once weekly after latent tuberculosis had been excluded. Follow-up visits were at week 4 and 12, subsequently every 12 weeks. RESULTS Mean age at the start of treatment was 11.8 (range 7-16), six patients were boys. Within three months, six patients reached Psoriasis Area and Severity Index (PASI) reduction of 75%. Two patients stopped use at week 12 because of ineffectiveness. Apart from local side reactions and minor infections, no adverse events were observed. CONCLUSION In our case series, etanercept proved to be an efficient drug in juvenile psoriasis without serious adverse events. However, patient registries and further randomized, double-blinded control studies are crucial to evaluate long-term efficacy and safety of etanercept.

Abstract
BACKGROUND & AIMS The IMAgINE 1 study (NCT00409682) evaluated the safety and efficacy of adalimumab double-blind maintenance dosing regimens following open-label induction for pediatric patients with moderate to severe Crohn's disease (CD). METHODS We studied 192 patients with Pediatric Crohn's Disease Activity Index (PCDAI) scores >30 for whom conventional treatment was unsuccessful. Patients received open-label induction therapy with subcutaneous adalimumab at weeks 0 and 2 (160 mg and 80 mg, or 80 mg and 40 mg, for body weight ≥40 kg or <40 kg). At week 4, 188 patients were assigned to groups based on achievement of clinical response (defined as decrease in PCDAI ≥15 points from baseline; 155/188 [82.4%]) and prior exposure to infliximab (82/188 [43.6%]). Groups were given double-blind maintenance therapy with adalimumab at high (40 mg or 20 mg for body weight ≥40 kg or <40 kg; n = 93) or low doses (20 mg or 10 mg for body weight ≥40 kg or <40 kg; n = 95) every other week for 48 weeks. Clinical remission (PCDAI ≤10) at week 26 (the primary end point) was compared between groups using the Cochran-Mantel-Haenszel test, adjusting for strata, with nonresponder imputation. Adverse events were monitored to evaluate safety. RESULTS A total of 152 of 188 patients (80.9%) completed all 26 weeks of the study. At week 26, 63 patients (33.5%) were in clinical remission, with no significant difference between high- and low-dose groups (36/93 [38.7%] vs 27/95 [28.4%]; P = .075). No new safety signals were detected. CONCLUSIONS Adalimumab induced and maintained clinical remission of children with CD, with a safety profile comparable to that of adult patients with CD. More children who received high compared with low dose were in remission at week 26, but the difference between dose groups was not statistically significant.

Abstract
Infliximab, adalimumab, and certolizumab are monoclonal antibodies against tumor necrosis factor-α (TNFα), a proinflammatory cytokine with an increased expression in the inflamed tissues of inflammatory bowel disease (IBD) patients. Currently, infliximab is the only anti-TNF drug that has been approved for use in refractory pediatric Crohn's disease (CD). Nevertheless, adalimumab and certolizumab have been used off-label to treat refractory pediatric IBD. Over the past 10 years, anti-TNF treatment has been of great benefit to many pediatric IBD patients, but their use is not without risks (infections, autoimmune diseases, malignancies). Despite the growing experience with these drugs in children with IBD, optimal treatment strategies still need to be determined. The purpose of this review is to summarize the current knowledge on the use of anti-TNF drugs in pediatric IBD and to discuss the yet-unsolved issues.

Abstract
INTRODUCTION Adalimumab is used to treat children with Crohn's disease (CD), but the effects of adalimumab on growth in CD have not been studied. AIM To study growth and disease activity over 12 months (6 months prior to (T-6), baseline (T0) and for 6 months following (T+6) adalimumab). SUBJECTS AND METHODS Growth and treatment details of 36 children (M: 22) who started adalimumab at a median (10th, 90th) age of 14.7 years (11.3, 16.8) were reviewed. RESULTS Of 36 cases, 28 (78%) went into remission. Overall 42% of children showed catch up growth, which was more likely in: (i) those who achieved remission (median change in height SDS (ΔHtSDS) increased from -0.2 (-0.9, 1.0) at T0 to 0.2 (-0.6, 1.6) at T+6, (p=0.007)), (ii) in those who were on immunosuppression ΔHtSDS increased from -0.2 (-0.9, 1.0) at T0 to 0.1 (-0.8, 1.3) at T+6, (p=0.03) and (iii) in those whose indication for using adalimumab therapy was an allergic reaction to infliximab, median ΔHtSDS increased significantly from -0.3 (-0.9, 1.0) at T0 to 0.3 (-0.5, 1.6) at T+6, (p=0.02). Median ΔHtSDS also increased from -0.4 (-0.8, 0.7) at T0 to 0.0 (-0.6, 1.6) at T+6, (p=0.04) in 15 children who were on prednisolone therapy when starting adalimumab. CONCLUSION Clinical response to adalimumab therapy is associated with an improvement in linear growth in a proportion of children with CD. Improved growth is more likely in patients entering remission and on immunosuppression but is not solely due to a steroid sparing effect.

Abstract
BACKGROUND Pivotal trials for adalimumab (ADA) demonstrated effectiveness versus placebo for induction and maintenance of remission in moderate to severely active Crohn's disease (CD). Although the approved maintenance regimen in the U.S. is 40 mg subcutaneously every 14 days, some patients require dose-escalation ([DE] either an increase in the delivered dose or decrease in the interval of treatment). Our objective was to determine which patient-, disease-, and therapy-related factors were associated with DE in CD patients treated with ADA. METHODS This retrospective medical record review of patients included all patients treated with ADA for CD at the University of Chicago Inflammatory Bowel Disease Center between 2003 and 2008. Patient-related factors, disease-related factors, and therapy-related factors were analyzed. Survival and logistic regression analyses were performed. RESULTS In all, 75 patients treated with ADA between December 2003 and June 2008 were identified. Thirty-one subjects (41%) required DE (32% male, median age 37.6, median disease duration 22.7 years) after a median 20 weeks of therapy (range 2-75). Patient-, clinical-, and therapy-related factors were similar between DE and non-DE. Need for DE was predicted by a family history of inflammatory bowel disease (IBD) (P = 0.0187). Time to DE was predicted by male gender, isolated colonic disease, and smoking history (all P < 0.05); however, only male gender was an independent predictor of time to DE. CONCLUSIONS In all, 41% of CD patients required ADA DE, with shorter time to DE in smokers, men, and patients with isolated colonic disease. Patients, caregivers, and insurers should anticipate DE when utilizing ADA in CD.

Abstract
Crohn's disease affects increasing numbers of children worldwide. Generally, childhood-onset disease runs a more severe course than in adults and has a greater impact on quality of life. Therapy in children must take account of a different set of risks for toxicity compared to adults, but also to their longevity. Biologic drugs present remarkable advantages in terms of disease control for children, especially in those whose disease cannot be controlled with conventional therapies, but their long-term risks are still being assessed. Data regarding biologic use in children is limited and mostly amounts to case series, but results have been promising, both in terms of controlling disease activity and improving growth parameters. Adverse reactions are infrequent in the short term, but loss of response is a long-term problem, particularly in children. More information is needed about very long term risks. Infliximab and adalimumab are the most studied agents in children, while there is relatively limited data on certolizumab and natalizumab. Further collection of data on these agents is still needed, but this should not restrict access to these agents for children in whom no other agent is effective.

Abstract
Inflammatory bowel disease (IBD), most commonly referring to Crohn's disease and ulcerative colitis, is a chronic and disabling condition with an increasing incidence in southern Europe. The etiology of IBD remains unknown, but the characteristic disproportionate inflammatory response in the gut may develop through various mechanisms at the cellular and subcellular level. Tumor necrosis factor (TNF) alpha is one crucial mediator of this abnormal immune response, and in recent years, biological therapies targeting TNFα have significantly improved the management of IBD refractory to conventional therapies. Infliximab is the best studied anti-TNFα agent, and is currently approved in the European Union for adults and children with Crohn's disease and adults with ulcerative colitis; adalimumab is indicated for Crohn's disease in adults but not children, while certolizumab was not approved in the European Union for Crohn's disease. Infliximab has confirmed efficacy in adults with Crohn's disease (including fistulizing disease) and ulcerative colitis, with benefits observed in both clinical remission and mucosal healing, it is similarly effective in children with Crohn's disease. Evidence suggests that early treatment with infliximab may improve the natural course of the disease. Adalimumab showed efficacy in adults with Crohn's disease and more limited data suggest efficacy in children with Crohn's disease. Although certolizumab pegol has also shown promising data in adults with Crohn's disease, data in children are lacking. Anti-TNFα agents are generally well tolerated, although careful monitoring for adverse events such as infections, infusion reactions, lymphomas and demyelinating diseases is warranted. A definitive causal relationship between anti-TNFα agents and various adverse events is difficult to establish, as the underlying disease and concomitant immunosuppression also predispose patients to such events. Infliximab has not been associated with an increased incidence of serious events, and adalimumab and certolizumab are also generally well tolerated in clinical trials. Both adalimumab and certolizumab pegol are associated with lower levels of drug antibodies compared with infliximab. Reactivation of latent tuberculosis is a potential risk with any anti-TNFα agent, and identification and treatment is required before initiating therapy. Although causal relationships are difficult to establish, caution is advised with anti-TNFα compounds in patients developing neurological symptoms suggestive of demyelinating disease, or in those at high risk of malignancy. Infliximab is also generally well tolerated in children; however, data are scarce for the other compounds. No increased risks associated with pregnancy have been observed for infliximab or adalimumab, but caution in pregnancy and during breast-feeding is currently advocated. In terms of future research, more long-term data are needed for both certolizumab pegol in Crohn's disease and adalimumab in ulcerative colitis. More research on the benefits of early biological treatment on disease progression is needed. In summary, the anti-TNFα inhibitors represent a momentous advance in the treatment of Crohn's disease and ulcerative colitis refractory to conventional treatments. They offer significant benefits in quality of life and mucosal healing, and may have the potential to change the evolution of the disease when given early.

Abstract
The objective of this study was to review loss of response and need for adalimumab dose intensification in adult and pediatric patients with Crohn's disease. Studies were identified through the electronic databases of MEDLINE and the annual meetings of Digestive Disease Week, of the United European Gastroenterology Week, and of the American College of Gastroenterology and the European Crohn's and Colitis Organization meetings. Studies evaluating loss of efficacy and/or need for dose intensification were included. Thirty-nine studies were included. The mean percentage of loss of response to adalimumab among primary responders was 18.2% and the annual risk was 20.3% per patient-year. The mean percentage of patients who required dose intensification among primary responders to adalimumab was 37% and the annual risk was 24.8% per patient-year. When considering initial responders and patients with primary non-response, the mean percentage of patients who needed an adalimumab dose escalation was 21.4% and the annual risk was 24.4% per patient-year. Pooled analysis showed that dose escalation permitted response to be regained in 71.4% and remission in 39.9% of patients. Predictors for loss of response or dose escalation were male gender, current/former smoker status, family history of inflammatory bowel disease, isolated colonic disease, extra-intestinal manifestations, 80/40 mg induction therapy, longer disease duration, greater baseline Crohn's Disease Activity Index, concomitant corticosteroid use, no deep remission at week 12, low serum trough concentrations of adalimumab, previous infliximab non-response and being previously treated with an anti-tumor necrosis factor agent. Overall, around one fifth of adult patients require dose intensification and experience a loss of response after initiation of adalimumab therapy. Adalimumab dose escalation permits response to be regained in the majority of patients.

Abstract
BACKGROUND Adalimumab is efficacious therapy for adults with Crohn's disease (CD). AIM To summarise the United Kingdom and Republic of Ireland paediatric adalimumab experience. METHODS British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) members with Inflammatory Bowel Disease (IBD) patients <18 years old commencing adalimumab with at least 4 weeks follow-up. Patient demographics and details of treatment were then collected. Response and remission was assessed using the Paediatric Crohn's Disease Activity Index (PCDAI)/Physicians Global Assessment (PGA). RESULTS Seventy-two patients [70 CD, 1 ulcerative colitis (UC), 1 IBD unclassified (IBDU)] from 19 paediatric-centres received adalimumab at a median age of 14.8 (IQR 3.1, range 6.1-17.8) years; 66/70 CD (94%) had previously received infliximab. A dose of 80 mg then 40 mg was used for induction in 41(59%) and 40 mg fortnightly for maintenance in 61 (90%). Remission rates were 24%, 58% and 41% at 1, 6 and 12 months, respectively. Overall 43 (61%) went into remission at some point, with 24 (35%) requiring escalation of therapy. Remission rates were higher in those on concomitant immunosuppression cf. those not on immunosuppression [34/46 (74%) vs. 9/24 (37%), respectively, (χ(2) 8.8, P=0.003)]. There were 15 adverse events (21%) including four (6%) serious adverse events with two sepsis related deaths in patients who were also on immunosuppression and home parenteral nutrition (3% mortality rate). CONCLUSIONS Adalimumab is useful in treatment of refractory paediatric patients with a remission rate of 61%. This treatment benefit should be balanced against side effects, including in this study a 3% mortality rate.

Abstract
Women with inflammatory bowel disease (IBD) have similar rates of fertility to the general population, but have an increased rate of adverse pregnancy outcomes compared with the general population, which may be worsened by disease activity. Infertility is increased in those undergoing ileal pouch-anal anastomosis. Anti-tumor necrosis factor therapy in pregnancy is considered to be low risk and compatible with use during conception in men and women and during pregnancy in at least the first two trimesters. Infliximab (IFX) and certolizumab pegol are also compatible with breastfeeding, but safety data for adalimumab (ADA) are awaited. The safety of natalizumab during pregnancy is unknown. For children with Crohn's disease (CD), IFX is effective at inducing and maintaining remission. Episodic therapy is not as effective as scheduled infusions. Disease duration in children does not appear to affect the efficacy of IFX. IFX promotes growth in prepubertal and early pubertal Crohn's patients. It is also effective for the treatment of extraintestinal manifestations. ADA is effective for children with active CD and for maintaining remission, even if they have lost response to IFX, although there are fewer data. Vaccination of infants exposed to biological therapy in utero should be given at standard schedules during the first 6 months of life, except for live-virus vaccines such as rotavirus. Inactivated vaccines may be safely administered to children with IBD, even when immunocompromised.

Abstract
INTRODUCTION Adalimumab is a fully-humanized anti-TNF a antibody that has showed its efficacy in Crohn's disease (CD) adult patients. Its less immunogenic composition seems to be an advantage compared to previous anti-TNF α, mainly infliximab. Good response to adalimumab has been reported in patients naïve to infliximab, in those in whom infliximab has shown no efficacy and in those intolerant or who have lost previous response to it. Adalimumab has shown also its efficacy as a second-line anti-TNF α in small series of paediatric CD but data regarding its use in children naïve to infliximab are scarce. AIM To report our experience with adalimumab as first line anti-TNF α treatment in paediatric CD. PATIENTS AND METHODS Four CD paediatric patients (2 boys) previously naïve to infliximab have received adalimumab. Mean age at diagnosis: 13 years, 4 months. Adalimumab was initiated in our patients soon after diagnosis (mean time from diagnosis: 8.5 months, range: 1 month 15 days-14 months) at decreasing loading doses (160 mg and 80 mg two weeks after) and then 40 mg subsequently every two weeks. RESULTS The four patients entered in remission after the first dose of adalimumab (mean previous PCDAI: 35, mean PCDAI after first dose: 3.6). No adverse effects were registered. Azathioprine was stopped after 4 months of combination therapy, without loss of efficacy or adverse reactions attributable to immunogenicity. All the 4 patients have remained in remission on adalimumab monotherapy for a mean follow-up of 17 months (range 9-20 months). CONCLUSION Adalimumab has shown its efficacy in our paediatric CD patients naïve to other anti-TNF α drugs. Early introduction of anti-TNF α antibodies in these patients could help to a better control of the disease. Its less immunogenicity and the possibility of a home-based administration are advantages when compared to other parenteral anti-TNF treatments. Change to monotherapy after prior successful combination therapy with azathioprine and adalimumab is a safe strategy that can help to minimize possible risks of intensive immunomodulation.
