Risk of Cancers in Patients with Pediatric Inflammatory Bowel Diseases: A Systematic Review and Meta-Analysis. J Pediatr 2021; 229:102-117.e36. [PMID: 32898579 DOI: 10.1016/j.jpeds.2020.08.087] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 08/13/2020] [Accepted: 08/28/2020] [Indexed: 12/16/2022]
Abstract
OBJECTIVES We performed a systematic review and meta-analysis to evaluate the risk of the development of cancers in patients with pediatric-onset inflammatory bowel disease (IBD). STUDY DESIGN A computerized literature search was performed. The primary outcome was the pooled incidence of cancer in studies reporting the risk as a standardized incidence ratio. The secondary outcomes were the pooled incidence rates of all cancers and site-specific cancers including colorectal cancer and hematologic cancers. RESULTS Sixty-six studies reporting outcomes in 38 092 patients were included. The pooled standardized incidence ratio for cancer was 2.39 (P < .0001, 95% CI 2.00-2.86) in IBD. The pooled incidence rates for cancer in patients with Crohn's disease (CD) and ulcerative colitis (UC) were 0.014 (95% CI 0.0087-0.021) and 0.031 (95% CI 0.018-0.052), respectively. The pooled incidence rate of colorectal cancer in CD and UC were 0.0075 (95% CI 0.0049-0.011) and 0.020 (95% CI 0.012-0.034), respectively. The pooled rates of hematologic cancers in CD and UC were 0.0061 (95% CI 0.0040-0.0090) and 0.0045 (95% CI 0.0026-0.0079), respectively. Cumulative meta-analyses showed a decreasing trend in the incidence of these cancers in both CD and UC. CONCLUSIONS Patients with pediatric-onset IBD had an increased risk of cancer development compared with the general population, however, incidence appeared to be decreasing in recent years.

Abstract
Background/Aims Information regarding the efficacy of early infliximab treatment in pediatric patients with Crohn’s disease (CD) is limited. We aimed to evaluate the impact of early combined immunosuppression on linear growth in pediatric patients with CD by performing step-up comparisons. Methods This retrospective study included pediatric patients with moderate-to-severe CD, who received a combination therapy with infliximab and azathioprine for at least 3 years and sustained corticosteroid-free remission without loss of response. The z-scores of the growth indicators obtained at the time of diagnosis and annually for 3 years thereafter were compared between the two groups. Results The early combined immunosuppression group displayed significantly increased linear growth 3 years after diagnosis (p=0.026). A significant difference was also observed in the linear growth 3 years after diagnosis between subgroups of Tanner stages 1–2 (p=0.016). Conclusions The early introduction of biologics should be considered to improve linear growth in pediatric patients with CD.

Abstract
BACKGROUND Early initiation of tumor necrosis factor-alpha inhibitor (TNFI) therapy for children and young adults with inflammatory bowel disease (IBD) is not well described. METHODS We conducted a retrospective cohort study of children and young adults (≤24 yr) newly diagnosed with IBD using health insurance claims from 2009 to 2013. The conventional "step-up" approach was defined as TNFI initiation >30 days after first IBD medication prescription, whereas the "top-down" approach was defined as new TNFI prescription within 30 days of first IBD medication prescription. Switching rates, time to initiation, discontinuation, and adherence to TNFIs were compared between the 2 strategies. RESULTS A total of 11,962 IBD patients were identified. Among 3300 TNFI users, 1298 (39.3%) were treated with the top-down approach, whereas 2002 (60.7%) were treated with the step-up approach. Top-down approach use increased from 31.4% to 49.8% during the 5-year period, and under this approach, most patients were treated with TNFIs alone. Time to TNFI initiation was shorter for patients diagnosed in more recent years. Patients treated with the top-down strategy had lower rates of corticosteroid use (32.5% versus 94.2%) compared with step-up treatment but presented a higher rate of TNFI discontinuation. The 2 strategies both exhibited high adherence (mean proportion of days covered: 83.7%-95.4%). CONCLUSIONS Early TNFI initiation increased over time for children and young adults with IBD and was related to lower rates of corticosteroid use compared with the conventional approach. However, the higher rate of TNFI discontinuation under the top-down approach requires further examination.

Abstract
The medical management of chronic inflammatory disorders in children, including mainly inflammatory bowel diseases and rheumatic diseases, has evolved dramatically over recent years with the advent of disease-modifying drugs such as immunomodulators and biological agents capable of interrupting the inflammatory cascade underlying these disorders. These agents are generally administered in patients who are refractory to conventional therapies. However, there is growing support that their use in the initial phases of these disorders, especially in pediatric patients, could interrupt and cease the inflammatory process. Thus, the aims of therapy have transitioned from symptomatic control to the achievement of deeper remission, including the healing of the inflammatory lesions combined with symptomatic remission. Therefore, more patients are currently receiving immunomodulators or biologics, frequently in addition to corticosteroids. Immunosuppression due to these therapies increases safety concerns, particularly regarding the risk of infections and malignancies. The available literature highlights how the combination of more than one of these therapies, especially if the combination includes corticosteroids, amplifies the risk of severe opportunistic infections. Otherwise, the infections described are mainly mild. Regarding malignancies, the overall risk associated with treatment appears non-significant in pediatric populations, but an appropriate benefit/risk assessment is recommended prior to the introduction of aggressive treatments such as immunomodulants and biologics. The background cancer risk related to the disease itself remains an issue. Protracted follow-up programs are needed, and the results from international multicenter registries are awaited to better understand the true risk related to therapy of these pediatric populations.

Abstract
Children and adolescents with Crohn's disease (CD) present often with a more complicated disease course compared to adult patients. In addition, the potential impact of CD on growth, pubertal and emotional development of patients underlines the need for a specific management strategy of pediatric-onset CD. To develop the first evidenced based and consensus driven guidelines for pediatric-onset CD an expert panel of 33 IBD specialists was formed after an open call within the European Crohn's and Colitis Organisation and the European Society of Pediatric Gastroenterolog, Hepatology and Nutrition. The aim was to base on a thorough review of existing evidence a state of the art guidance on the medical treatment and long term management of children and adolescents with CD, with individualized treatment algorithms based on a benefit-risk analysis according to different clinical scenarios. In children and adolescents who did not have finished their growth, exclusive enteral nutrition (EEN) is the induction therapy of first choice due to its excellent safety profile, preferable over corticosteroids, which are equipotential to induce remission. The majority of patients with pediatric-onset CD require immunomodulator based maintenance therapy. The experts discuss several factors potentially predictive for poor disease outcome (such as severe perianal fistulizing disease, severe stricturing/penetrating disease, severe growth retardation, panenteric disease, persistent severe disease despite adequate induction therapy), which may incite to an anti-TNF-based top down approach. These guidelines are intended to give practical (whenever possible evidence-based) answers to (pediatric) gastroenterologists who take care of children and adolescents with CD; they are not meant to be a rule or legal standard, since many different clinical scenario exist requiring treatment strategies not covered by or different from these guidelines.

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
An expert panel of the European Crohn's and Colitis Organisation (ECCO) and European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) initiated a consensus process to produce the first pediatric specific ulcerative colitis (UC) guidelines based on a systematic literature review. Treatment strategies must reflect that pediatric-onset UC has a slightly different phenotype than adult-onset disease with more often extensive (pancolitis) and more aggressive disease course. Other pediatric-specific aspects include growth, puberty, bone density accrual and emotional development and body image acquisition. These differences and others influenced the development of pediatric treatment algorithms. It is recommended that virtually all children with UC must be treated with some maintenance therapy and 5-ASA requirement and dosing are often higher in children. A larger number of children are at risk for steroid-dependency, and this should not be tolerated; steroid sparing strategies with early use of immunosuppressors are recommended in high-risk patients. On the other hand, the safety profile of immunosuppressive therapy in children includes the rare forms of lymphomas and many future treatment years. Colectomy and pouch formation should be balanced in the treatment algorithms against the higher rate of future infertility in girls. The acute and on-going management of pediatric UC should be guided by evidence- and consensus-based balanced decisions, reflecting a vision of long-term treatment goals.

Abstract
The ErbB tyrosine kinases (epidermal growth factor receptor (EGFR), ErbB2/HER2, ErbB3, and ErbB4) are cell surface growth factor receptors widely expressed in many developing mammalian tissues, including in the intestinal tract. Signaling elicited by these receptors promotes epithelial cell growth and survival, and ErbB ligands have been proposed as therapeutic agents for intestinal diseases of pediatric populations, including inflammatory bowel disease (IBD), necrotizing enterocolitis (NEC), and inflammation associated with total parenteral nutrition (TPN). Furthermore, emerging evidence points to reduced ErbB ligand expression and thus reduced ErbB activity in IBD, NEC, and TPN models. This review will discuss the current understanding of the role of ErbB receptors in the pathogenesis and potential treatment of pediatric intestinal inflammation, with focus on the altered signaling in disease and the molecular mechanisms by which exogenous ligands are protective.

Abstract
OBJECTIVES The paediatric dentist must be familiar with a range of medical problems which can affect the mouth or general health of children. Dental clinicians are ideally placed to help with the detection of a range of gastrointestinal issues and should know when to refer to the paediatric specialist for advice. METHODS This article reviews the common gastrointestinal tract (GIT) conditions that can affect children reviewing the conditions, their usual treatments, and how they can influence the mouth and the oral environment. This article will review how the different conditions may produce oral symptoms and signs. The management of the oral problems and appropriate photographs are covered well in other texts and will not be included here. CONCLUSION The mouth is a specialised part of the GIT and can be involved in or affected by many of the diseases encountered in other GIT regions.

Abstract
BACKGROUND AND AIMS Exclusive enteral nutrition (EEN) induces remission in patients with Crohn's disease (CD). We investigated the short-term impact of EEN on bone quality and muscle mass in children with CD. METHODS Ten newly diagnosed CD patients (7 male, 10.6-17.7 years of age) were assessed by peripheral quantitative computed tomography (pQCT) at the forearm before starting an 8-weeks treatment with EEN, and after 12 and 52 weeks. No steroids or biologicals were applied. Trabecular and cortical bone mineral density, total bone, and muscle cross-sectional area (CSA) were measured by pQCT and expressed as age- and sex-specific z-scores; size-dependent CSAs were corrected for low height for age. Wilcoxon rank sum test was applied. RESULTS Remission at week 12 was achieved in 8 patients; 2 still had mild disease. Initially low trabecular density z-scores improved (+0.3; p = 0.006) at week 12; simultaneously, the increased cortical density z-scores normalized (-0.4; p = 0.027). The low z-score for muscle CSA corrected for height (median -2.5, range -3.49 to -0.97) increased within 12 weeks (+1.0; p = 0.002) with no further improvement thereafter. CONCLUSIONS The results indicate disturbed bone remodeling and severely impaired muscle mass in newly diagnosed CD children. Bone metabolism and muscle mass improved within 3 months after starting EEN with no further normalization thereafter.

Abstract
The incidence of inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis, in children is on the rise. Pediatric patients with IBD are especially vulnerable to the physical and psychosocial morbidities of this disorder. Unique aspects of pediatric IBD patients compared to adult patients warrants an individualized approach to management regardless of age. This review focuses on the special aspects of pediatric IBD and the implications for the diagnosis and management of this disease.

Allergy-associated symptoms in relation to childhood non-Hodgkin's as contrasted to Hodgkin's lymphomas: a case-control study in Greece and meta-analysis. Eur J Cancer 2012; 48:1860-6.

Abstract
An increase of the prevalence of childhood allergic diseases and the incidence of childhood Hodgkin's (HL) and non-Hodgkin's lymphoma (NHL) were reported in the late 20th century. Among adults, several studies point to an inverse association with lymphoma; it remains to be confirmed whether allergy is also related to childhood lymphomas and whether the association, if any, is of an aetiologic nature. Between 1996 and 2008, 277 children (aged 0-14 years) with HL (N = 111) or NHL (N = 166) were enrolled in Nationwide Registry for Childhood Hematological Malignancies (NARECHEM), a Greek hospital-based-registry of childhood hematological malignancies. Hospital controls were individually matched to cases on age and sex. Multivariate conditional logistic regression was used to estimate odds ratios (ORs) with 95%confidence intervals (CIs) for associations of allergic diseases and other covariates with childhood HL or NHL risk. Subsequently, we combined our results with those of a French case-control study in a meta-analysis amounting to a total of 330 NHL cases/1478 controls and 239 HL cases/959 controls. After controlling for sociodemographic, perinatal and environmental factors, childhood NHL was less prevalent among children with allergy-associated symptoms overall (OR:0.50, 95%CI:0.27-0.92) or a history of asthma (OR:0.43, 95%CI:0.21-0.88). By contrast, allergy did not seem to be associated with childhood HL risk, although statistical power was limited. Fewer seaside holidays and higher birth weight were also associated with increased childhood NHL risk. The combined OR of the two studies for the association of asthma with NHL risk was: 0.52, 95%CI:0.32-0.84, whereas for HL: 0.86, 95%CI:0.51-1.45. Allergy seems to be strongly and inversely associated with childhood NHL. It remains to be elucidated in future investigations comprising larger populations, focusing on specific disease subtypes and employing more pertinent study-designs, whether this association is genuinely protective.

Abstract
Inflammatory bowel disease (IBD) affects ≈1.4 million people in North America and, because of its typical early age of onset and episodic disease course, IBD patients often undergo numerous imaging studies over the course of their lifetimes. Computed tomography (CT) has become the standard imaging modality for assessment of IBD patients because of its widespread availability, rapid image acquisition, and ability to evaluate intraluminal and extraluminal disease. However, repetitive CT imaging has been associated with a significant ionizing radiation risk to patients, making MRI an appealing alternative IBD imaging modality. Pelvic MRI is currently the imaging gold standard for detecting perianal disease, while recent studies indicate that MRI bowel-directed techniques (enteroclysis, enterography, colonography) can accurately evaluate bowel inflammation in IBD. With recent technical innovations leading to faster and higher resolution body MRI, the role of MRI in IBD evaluation is likely to continue to expand. Future applications include surveillance imaging, detection of mural fibrosis, and early assessment of therapy response.

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
TNF inhibitors and other biologicals have greatly expanded the therapeutic options for juvenile idiopathic arthritis (JIA). While the efficacy of etanercept and adalimumab has been proven in randomized controlled clinical trials, their long-term safety remains the subject of ongoing investigations. Reports of leukaemia and tumours in children and adolescents treated with etanercept, infliximab and adalimumab have raised questions about an increased risk for malignancies, with lymphoma accounting for the largest group at 50% of all 48 malignancies reported by the FDA.Consequently, TNF inhibitors should be indicated under careful consideration of individual risk factors, such as increased family occurrence of malignancies, or pre-treatment with carcinogenic substances such as cyclophosphamide. This is particularly true for non-approved substances, and non-approved indications, and for combination therapy of TNF inhibitors with immunosuppressive drugs. On the other hand, however, treatment should not be stopped or started in any patient in whom treatment is necessary due to the current knowledge. Adequate patient information, surveillance and documentation of treatment in the registry of the GKJR is strongly recommended.

Abstract
OBJECTIVE This article reviews the current literature and knowledge about hepatosplenic T-cell lymphoma (HSTCL), providing an overview of the clinical features, a description of its pathology and immunophenotypic traits in relation to other lymphomas. In addition, we explore the history of reported cases of hepatosplenic T-cell lymphoma in relation to the possible existence of a causal relationship between infliximab use and HSTCL. The treatments for HSTCL will be briefly addressed. METHODS A comprehensive literature search using multiple databases was performed. Keyword search phrases including "lymphoma," "hepatosplenic T-cell lymphoma," "Inflammatory bowel disease," "6-mercaptopurine," and "infliximab" were used in various combinations. In addition references from published papers were reviewed as well. RESULTS There are over 200 reported cases of HSTCL. Only 22 cases of hepatosplenic T-cell lymphoma are associated with IBD treatment. Clinicians usually reserve immunomodulators and biologics for moderate to severe IBD cases. The ultimate goal of therapy is to control inflammation and therefore allow mucosal healing. IBD patients demonstrating mucosal healing are less likely to undergo surgery and experience complications related to their disease. We manipulate the immune system with corticosteroids, immunomodulators, and biologics, therefore causing bone marrow suppression. With bone marrow suppression, malignant degeneration may begin through selective uncontrolled cell proliferation, initiating HSTCL development in the genetically susceptible. CONCLUSION Hepatosplenic T-cell lymphoma is a rare disease, often with a poor outcome. With the increasing number of reported cases of HSTCL linked to the use of infliximab, adalimumab, and AZA/6-MP, there appears to be an undeniable association of HSTCL development with the use of these agents. This risk is unquantifiable. When considering the rarity of cases and the multiple complications with uncontrolled disease, however, the benefit of treatment far outweighs the risk.

Abstract
BACKGROUND Patients with ulcerative colitis often receive thiopurines as immunomodulators (IMs) to maintain remission and avoid corticosteroids. If unresponsive or intolerant to these agents, patients are treated with methotrexate, an antimetabolite never assessed in paediatric ulcerative colitis. AIM To describe the experience with methotrexate in children with ulcerative colitis. METHODS Thirty-two patients (median age 13.9 years) received methotrexate. Pediatric Ulcerative Colitis Activity Index (PUCAI) and use of corticosteroids were the main outcomes evaluated at baseline and at 3, 6 and 12 months. RESULTS Indications to methotrexate were azathioprine unresponsiveness in 18 patients, azathioprine intolerance/toxicity in 10 and spondyloarthropathy in four. Response or remission was achieved in 72%, 63% and 50% of patients at 3, 6 and 12 months respectively. Mean PUCAI were 49.5 ± 23.3 at baseline and 32.9 ± 21.9, 29.5 ± 21.8 and 29.4 ± 19.9 at 3, 6 and 12 months respectively (P: 0.03). At the beginning of methotrexate, 16 patients (50%) received corticosteroids that were discontinued in 13 of them (81%) by 6 months. At the end of the study, 11 patients (33%) needed short courses of corticosteroids for disease relapse. CONCLUSIONS Methotrexate may be useful in treating children with ulcerative colitis, although large, controlled trials are warranted to define better its effectiveness.

Abstract
Chronic inflammation is strongly associated with approximately 1/5th of all human cancers. Arising from combinations of factors such as environmental exposures, diet, inherited gene polymorphisms, infections, or from dysfunctions of the immune response, chronic inflammation begins as an attempt of the body to remove injurious stimuli; however, over time, this results in continuous tissue destruction and promotion and maintenance of carcinogenesis. Here we focus on intestinal inflammation and its associated cancers, a group of diseases on the rise and affecting millions of people worldwide. Intestinal inflammation can be widely grouped into inflammatory bowel diseases (ulcerative colitis and Crohn's disease) and celiac disease. Long-standing intestinal inflammation is associated with colorectal cancer and small-bowel adenocarcinoma, as well as extraintestinal manifestations, including lymphomas and autoimmune diseases. This article highlights potential mechanisms of pathogenesis in inflammatory bowel diseases and celiac disease, as well as those involved in the progression to associated cancers, most of which have been identified from studies utilizing mouse models of intestinal inflammation. Mouse models of intestinal inflammation can be widely grouped into chemically induced models; genetic models, which make up the bulk of the studied models; adoptive transfer models; and spontaneous models. Studies in these models have lead to the understanding that persistent antigen exposure in the intestinal lumen, in combination with loss of epithelial barrier function, and dysfunction and dysregulation of the innate and adaptive immune responses lead to chronic intestinal inflammation. Transcriptional changes in this environment leading to cell survival, hyperplasia, promotion of angiogenesis, persistent DNA damage, or insufficient repair of DNA damage due to an excess of proinflammatory mediators are then thought to lead to sustained malignant transformation. With regards to extraintestinal manifestations such as lymphoma, however, more suitable models are required to further investigate the complex and heterogeneous mechanisms that may be at play.

Abstract
OBJECTIVES The use of tumor necrosis factor-alpha (TNF-alpha) antagonists has changed the therapeutic strategy for Crohn's disease (CD). Adalimumab (ADA), a fully human anti-TNF-alpha monoclonal antibody, is an effective therapy for patients with CD, both naive patients and those intolerant or refractory to Infliximab (IFX), a chimeric anti-TNF-alpha agent. However, the use of ADA is rarely reported in pediatric CD. We performed an open prospective evaluation of short- and long-term efficacy and safety of ADA in children with moderate-to-severe CD. METHODS A total of 23 pediatric CD patients (9 naive and 14 intolerant or unresponsive to IFX) received ADA subcutaneously as a loading schedule at weeks 0 and 2, and at every other week (eow) during a 48-week maintenance phase. Loading and maintenance doses were 160/80 and 80 mg eow in 13 cases, 120/80 and 80 mg eow in 2, and 80/40 and 40 mg eow in 8 cases. The primary efficacy outcomes were clinical remission and response at different scheduled visits along the maintenance phase. At baseline, 13 patients also received immunomodulators (IMs). RESULTS At weeks 2, 4, 12, 24, and 48, remission rates were 36.3, 60.8, 30.5, 50, and 65.2%, respectively, whereas response rates were 87, 88, 70, 86, and 91%, respectively. Four patients at week 24 and 2 at week 48 received IMs; the mean daily corticosteroid dose, disease activity index, C-reactive protein level, and erythrocyte sedimentation rate decreased significantly throughout the trial. No serious adverse events were recorded. CONCLUSIONS ADA can be an effective and safe biological agent for inducing and maintaining remission in children with moderate-to-severe CD, even in those with previous IFX therapy.
