Tumor necrosis factor alpha blockers and malignancy in children: forty-eight cases reported to the Food and Drug Administration

Update on non-infectious uveitis treatment: anti-TNF-alpha and beyond

Non-infectious uveitis (NIU) encompasses a range of conditions marked by inflammation within various layers of the eye. NIU is a significant contributor to irreversible vision loss among the working-age population in developed countries. The aim of treating uveitis is to manage inflammation, prevent its recurrences and to restore or salvage vision. Presently, the standard treatment protocol for NIU involves initiating corticosteroids as the primary therapeutic agents, although more aggressive approaches and steroid sparing agent may be necessary in certain cases. These advanced treatments option include synthetic immunosuppressants like antimetabolites, calcineurin inhibitors and alkylating agents. For patients who exhibit an intolerance or resistance to corticosteroids and conventional immunosuppressive therapies, biologic agents have emerged as a promising alternative. Notably, among the biologic treatments evaluated, TNF-α inhibitors, anti-CD20 therapy and alkylating agents have shown considerable efficacy. In this review, we delve into the latest evidence surrounding the effectiveness of biologic therapy and introduce novel therapeutic strategies targeting immune components as potential avenues for advancing treatment of NIU.

Characteristic analysis of adverse reactions of five anti-TNFɑ agents: a descriptive analysis from WHO-VigiAccess

Introduction: Tumor necrosis factor (TNF) inhibitors (adalimumab, infliximab, etanercept, golimumab, and certolizumab pegol) have revolutionized the treatment of severe immune-mediated inflammatory diseases, including rheumatoid arthritis, Crohn's disease, psoriatic arthritis, ankylosing spondylitis, and ulcerative colitis. This study assessed adverse drug reactions (ADRs) after the use of TNFα inhibitors in VigiAccess of the World Health Organization (WHO) and compared the adverse reaction characteristics of five inhibitors to select the drug with the least risk for individualized patient use. Methods: The study was a retrospective descriptive analysis method in design. We sorted out five marketed anti-TNFα drugs, and their ADR reports were obtained from WHO-VigiAccess. Data collection included data on the age groups, sex, and regions of patients worldwide covered by ADR reports, as well as data on disease systems and symptoms caused by ADRs recorded in annual ADR reports and reports received by the WHO. By calculating the proportion of adverse reactions reported for each drug, we compared the similarities and differences in adverse reactions for the five drugs. Results: Overall, 1,403,273 adverse events (AEs) related to the five anti-TNFα agents had been reported in VigiAccess at the time of the search. The results show that the 10 most commonly reported AE manifestations were rash, arthralgia, rheumatoid arthritis, headache, pneumonia, psoriasis, nausea, diarrhea, pruritus, and dyspnea. The top five commonly reported AE types of anti-TNFα drugs were as follows: infections and infestations (184,909, 23.0%), musculoskeletal and connective tissue disorders (704,657, 28.6%), gastrointestinal disorders (122,373, 15.3%), skin and subcutaneous tissue disorders (108,259, 13.5%), and nervous system disorders (88,498, 11.0%). The preferred terms of myelosuppression and acromegaly were obvious in golimumab. Infliximab showed a significantly higher ADR report ratio in the infusion-related reaction compared to the other four inhibitors. The rate of ADR reports for lower respiratory tract infection and other infections was the highest for golimumab. Conclusion: No causal associations could be established between the TNFα inhibitors and the ADRs. Current comparative observational studies of these inhibitors revealed common and specific adverse reactions in the ADR reports of the WHO received for these drugs. Clinicians should improve the rational use of these high-priced drugs according to the characteristics of ADRs.

Low Risk of Lymphoma in Pediatric Patients Treated for Inflammatory Bowel Disease

INTRODUCTION

Despite the effectiveness of immune-suppressing therapies in treating pediatric inflammatory bowel diseases (IBDs), concerns of lymphoma may limit their use. We used a large administrative claims database to evaluate the risk of lymphoma in pediatric IBD and conducted a case series analysis of medication exposure in children diagnosed with lymphoma.

METHODS

We analyzed administrative claims from the 2007 to 2018 IQVIA database and identified pediatric (≤18 years) patients with Crohn's disease or ulcerative colitis using International Classification of Diseases, 9th or 10th Revision codes and pharmacy claims. Lymphoma cases were identified by diagnosis codes and confirmed by independent claim-by-claim review by a pediatric oncologist and gastroenterologist. We calculated incidence rates for lymphoma among patients with and without pharmacy claims for treatment followed by treatment description among those who developed lymphoma during follow-up.

RESULTS

A total of 10,777 pediatric patients with IBD received ≥1 IBD therapy (median age 15 years [12-17], 45% female and 61% diagnosed with Crohn's disease) during 28,292 patient-years of follow-up. Among treated patients, 5 lymphoma cases were identified (incidence rate 17.7/100,000 patient-years; 95% confidence interval 6.5-39.2). Of these, 4 were treated with a thiopurine before lymphoma diagnosis, and none received anti-tumor necrosis factor-α (anti-TNF) monotherapy.

DISCUSSION

The overall lymphoma incidence was low among our cohort of treated pediatric patients with IBD. We observed no cases of lymphoma among patients prescribed anti-TNF monotherapy. These findings reinforce the relative safety of anti-TNF monotherapy for the treatment of pediatric IBD.

Emerging therapies for juvenile arthritis: agents in early clinical trials

INTRODUCTION

Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory rheumatic condition in childhood. The management of JIA has been revolutionized thanks to the development of new powerful drugs and the possibility to conduct controlled clinical trials with support from legislative initiatives and availability of international collaborative networks. Trials are still needed in children because we now have new drugs related to specific JIA category.

AREAS COVERED

The review is centered on the latest achievements in the field, focusing on new investigational drugs which are currently or have been recently tested for JIA treatment, encompassing agents in early phase of clinical development.

EXPERT OPINION

Despite the tremendous improvement witnessed in the field of JIA treatment in the past 20 years, there are still many unmet needs to be prioritized. Studies on disease pathogenesis will hopefully help in the identification of new treatment targets for individual JIA categories, that could possibly favor a stricter disease control and contribute to solve the issue of refractory JIA. Novel strategies aimed at the prevention of the risk of long-term joint damage are also desirable, as well as the discovery of predictive biomarkers for treatment efficacy and safety in the individual patient.

Myelolipoma After Infliximab Treatment for Crohn's Disease

A 20-year-old woman with Crohn's disease receiving infliximab therapy presented to the emergency department with lower extremity swelling secondary to compression of the common iliac vein. On magnetic resonance imaging, an enlarging pelvic mass was identified. The pathology of the mass was consistent with myelolipoma. We believe this is the first case of myelolipoma in a patient on immunosuppression with infliximab.

Gut and liver involvement in pediatric hematolymphoid malignancies

Hematolymphoid malignancies are common neoplasms in childhood. The involvement of the gastrointestinal (GI) tract, liver, biliary system, pancreas, and peritoneum are closely interlinked and commonly encountered. In leukemias, lymphomas, and Langerhans cell histiocytosis (LCH), the manifestations result from infiltration, compression, overwhelmed immune system, and chemotherapy-induced drug toxicities. In acute leukemias, major manifestations are infiltrative hepatitis, drug induced gastritis, neutropenic typhlitis and chemotherapy related pancreatitis. Chronic leukemias are rare. Additional presentation in lymphomas is cholestasis due to infiltration or biliary obstruction by lymph nodal masses. Presence of ascites needs a thorough workup for the underlying pathophysiology that may modify the therapy and affect the outcome. Uncommon hematolymphoid malignancies are primary hepatic, hepatosplenic, and GI lymphomas which have strict definitions. In advanced diseases with extensive spread, it may be impossible to distinguish these diseases from the primary site of origin. LCH produces biliary strictures that mimic as sclerosing cholangitis. Liver infiltration is associated with poor liver recovery even after chemotherapy. The heterogeneity of gut and liver manifestations in hematolymphoid malignancies has a clinical impact on their management. Though chemotherapy is the mainstay of therapy in all hematolymphoid malignancies, debulking surgery and radiotherapy have an adjuvant role in specific clinical scenarios. Rare situations presenting as liver failure or end-stage liver disease require liver transplantation. At their initial presentation to a primary care physician, given the ambiguity in clinical manifestations and the prognostic difference with time-bound management, it is vital to recognize them early for optimal outcomes. Pooled data from robust registries across the world is required for better understanding of these complications.

Juvenile idiopathic arthritis

Juvenile idiopathic arthritis (JIA) is an umbrella term for arthritis of unknown origin, lasting for >6 weeks with onset before 16 years of age. JIA is the most common chronic inflammatory rheumatic condition of childhood. According to the International League Against Rheumatism (ILAR) classification, seven mutually exclusive categories of JIA exist based on disease manifestations during the first 6 months of disease. Although the ILAR classification has been useful to foster research, it has been criticized mainly as it does not distinguish those forms of chronic arthritis observed in adults and in children from those that may be unique to childhood. Hence, efforts to provide a new evidence-based classification are ongoing. Similar to arthritis observed in adults, pathogenesis involves autoimmune and autoinflammatory mechanisms. The field has witnessed a remarkable improvement in therapeutic possibilities of JIA owing to the availability of new potent drugs and the possibility to perform controlled trials with support from legislative interventions and large networks availability. The goal of drug therapy in JIA is to rapidly reduce disease activity to inactive disease or clinical remission, minimize drug side effects and achieve a quality of life comparable to that of healthy peers. As JIA can influence all aspects of a child's and their family's life, researchers increasingly recognize improvement of health-related quality of life as a key treatment goal.

Association of cancer with comorbid inflammatory conditions and treatment in patients with Lynch syndrome

BACKGROUND

Individuals with Lynch syndrome (LS) and hereditary non-polyposis colorectal cancer (HNPCC) are at increased risk of both colorectal cancer and other cancers. The interplay between immunosuppression, a comorbid inflammatory condition (CID), and HNPCC on cancer risk is unclear.

AIM

To evaluate the impact of CIDs, and exposure to monoclonal antibodies and immunomodulators, on cancer risk in individuals with HNPCC.

METHODS

Individuals prospectively followed in a hereditary cancer registry with LS/HNPCC with the diagnosis of inflammatory bowel disease or rheumatic disease were identified. We compared the proportion of patients with cancer in LS/HNPCC group with and without a CID. We also compared the proportion of patients who developed cancer following a CID diagnosis based upon exposure to immunosuppressive medications.

RESULTS

A total of 21 patients with LS/HNPCC and a CID were compared to 43 patients with LS/HNPCC but no CID. Cancer occurred in 84.2% with a CID compared to 76.7% without a CID (P = 0.74) with no difference in age at first cancer diagnosis 45.5 ± 14.6 vs 43.8 ± 7.1 years (P = 0.67). LS specific cancers were diagnosed in 52.4% with a CID vs 44.2% without a CID (P = 0.54). Nine of 21 (42.9%) patients were exposed to biologics or immunomodulators for the treatment of their CID. Cancer after diagnosis of CID was seen in 7 (77.8%) of exposed individuals vs 5 (41.7%) individuals unexposed to biologics/immunomodulators (P = 0.18). All 7 exposed compared to 3/5 unexposed developed a LS specific cancer. The exposed and unexposed groups were followed for a median 10 years and 8.5 years, respectively. The hazard ratio for cancer with medication exposure was 1.59 (P = 0.43, 95%CI: 0.5-5.1).

CONCLUSION

In patients with LS/HNPCC, the presence of a concurrent inflammatory condition, or use of immunosuppressive medication to treat the inflammatory condition, might not increase the rate of cancer occurrence in this limited study.

Autoimmunity and cancer

In many autoimmune rheumatic diseases, there is an increased risk of cancer compared to the general population. The link between autoimmunity and cancer is dynamic and bidirectional. Recent advances in terms of knowledge of biology, epidemiology, and long-term outcomes for the autoimmune rheumatic diseases have revealed several new connections between these two entities. Data suggest that chronic inflammation from the rheumatic diseases or their therapies may contribute to the onset and promotion of cancer. Conversely, antitumor immune responses may become cross-reactive with self-tissues resulting in the development of autoimmunity. In this review, we discuss about the potential mechanisms that link autoimmune rheumatic diseases and cancer and the association of malignancies with common autoimmune disorders. The increased incidence of malignancy in autoimmune rheumatic diseases has been largely described, although the biology underpinning this relationship should be further investigated. The development of evidence-based cancer screening recommendations in patients with autoimmune rheumatic diseases is complex due to the heterogeneity of clinical rheumatic phenotypes, cancer sites at risk and exposure to anti-neoplastic and anti-rheumatic treatment. In order to lay the foundation of risk stratification and targeted cancer screening, larger longitudinal cohort studies that provide a more detailed framework of the links between cancer and autoimmunity are urgently needed.

The Efficacy of Adalimumab as an Initial Treatment in Patients with Behçet's Retinal Vasculitis

Background: No study has evaluated the effectiveness of Adalimumab (ADA) as first-line in treatment-naïve patients with retinal vasculitis due to Behçet’s Uveitis (BU).

Objective: To compare the efficacy of ADA plus conventional therapy and conventional therapy alone as initial treatments in naïve BU patients characterized by retinal vasculitis.

Methods: Medical records of BU patients characterized by retinal vasculitis treated with conventional therapy (CT, refers to glucocorticoid and immunosuppressive agents) alone or ADA plus conventional therapy with at least 6 months of follow-up between February 2015 and June 2020 were analyzed. Only patients who were first diagnosed with BU without previous systemic treatment were reviewed. The retinal vasculitis score based on fluorescein angiography (FA), best-corrected visual acuity, glucocorticoid-sparing effect, the number of relapses and ocular complications were evaluated.

Results: A total of 45 patients (87 eyes) were included. Twenty-four patients (55.33%) in the CT group were treated with conventional therapy and 21 patients (46.67%) in the ADA group were treated with ADA plus conventional therapy. The inflammatory parameters improved in both groups. FA scores showed significantly greater improvement in ADA group than CT group (p < 0.001). The median number of relapses was significantly lower, and the duration of remission was longer in ADA group than CT group (p < 0.001). At the last visit, a significantly better BCVA improvement (p = 0.024), better inflammation control (anterior chamber inflammation p = 0.017 and vitritis p < 0.001) and lower daily glucocorticoid dosage (p = 0.005) were identified in patients received ADA therapy. In CT group, 1 patient suffered hepatitis B and tuberculosis, 1 had growth retardation, 1 patient had with osteoporosis, then followed by other mild AEs (mostly respiratory upper tract infections); while in ADA group, 1 patient experienced a mild pneumonia (n = 1) while milder AEs were represented mostly by respiratory upper tract infections followed by gastrointestinal discomfort.

Conclusion: ADA plus conventional therapy achieved superiority over conventional therapy as initial treatment in naïve BU patients with retinal vasculitis.

Practical recommendations for systemic treatment in psoriasis according to age, pregnancy, metabolic syndrome, mental health, psoriasis subtype and treatment history (BETA-PSO: Belgian Evidence-based Treatment Advice in Psoriasis; part 1)

Background

Impressive progress in new therapeutic options has been made for psoriasis. Treatments include topical steroids, phototherapy, conventional, synthetic disease‐modifying drugs and an expanding list of biologics.

Objective

The primary objective of this work was to collect evidence for the creation of practice guidelines for systemic treatment of psoriasis (BETA‐PSO: Belgian Evidence‐based Treatment Advice in Psoriasis).

Methods

Evidence‐based recommendations were formulated using a quasi‐Delphi methodology after a systematic search of the literature and a consensus procedure involving 8 psoriasis experts.

Results

In this part, the use of systemic treatment in different age groups, during pregnancy, in metabolic syndrome, in patients with mental health problems, in different psoriasis subtypes and in previously systemically treated patients treatment is discussed.

Conclusion

Guidance on therapeutic choice in specific clinical situations in psoriasis is provided in order to facilitate the decision‐making in clinical practice.

TNF in the era of immune checkpoint inhibitors: friend or foe?

Immune checkpoint inhibitors (ICIs) are effective in the treatment of patients with advanced cancer and have emerged as a pillar of standard cancer care. However, their use is complicated by adverse effects known as immune-related adverse events (irAEs), including ICI-induced inflammatory arthritis. ICI-induced inflammatory arthritis is distinguished from other irAEs by its persistence and requirement for long-term treatment. TNF inhibitors are commonly used to treat inflammatory diseases such as rheumatoid arthritis, spondyloarthropathies and inflammatory bowel disease, and have also been adopted as second-line agents to treat irAEs refractory to glucocorticoid treatment. Experiencing an irAE is associated with a better antitumour response after ICI treatment. However, whether TNF inhibition can be safely used to treat irAEs without promoting cancer progression, either by compromising ICI therapy efficacy or via another route, remains an open question. In this Review, we discuss clinical and preclinical studies that address the relationship between TNF, TNF inhibition and cancer. The bulk of the evidence suggests that at least short courses of TNF inhibitors are safe for the treatment of irAEs in patients with cancer undergoing ICI therapy. Data from preclinical studies hint that TNF inhibition might augment the antitumour effect of ICI therapy while simultaneously ameliorating irAEs.

Making Decisions About Stopping Medicines for Well-Controlled Juvenile Idiopathic Arthritis: A Mixed-Methods Study of Patients and Caregivers

OBJECTIVE

Improved treatments for juvenile idiopathic arthritis (JIA) have increased remission rates. We conducted this study to investigate how patients and caregivers make decisions about stopping medications when JIA is inactive.

METHODS

We performed a mixed-methods study of caregivers and patients affected by JIA, recruited through social media and flyers, and selected by purposive sampling. Participants discussed their experiences with JIA, medications, and decision-making through recorded telephone interviews. Of 44 interviewees, 20 were patients (50% ages <18 years), and 24 were caregivers (50% caring for children ages ≤10 years). We evaluated characteristics associated with high levels of reported concerns about JIA or medicines using Fisher's exact testing.

RESULTS

Decisions about stopping medicines were informed by competing risks between disease activity and treatment. Participants who expressed more concerns about JIA were more likely to report disease-related complications (P = 0.002) and more motivated to continue treatment. However, participants expressing more concern about medicines were more likely to report treatment-related complications (P = 0.04) and felt more compelled to stop treatment. Additionally, participants considered how JIA or treatments facilitated or interfered with their sense of normalcy and safety, expressed feelings of guilt and regret about previous or potential adverse events, and reflected on uncertainty and unpredictability of future harms. Decision-making was also informed by trust in rheumatologists and other information sources (e.g., family and online support groups).

CONCLUSION

When deciding whether to stop medicines whenever JIA is inactive, patients and caregivers weigh competing risks between disease activity and treatment. Based on our results, we suggest specific approaches for clinicians to perform shared decision-making regarding stopping medicines for JIA.

Comparative study of adalimumab versus conventional therapy in sight-threatening refractory Behçet's uveitis with vasculitis

BACKGROUND

Anti-tumor necrosis factor-alpha was regarded as an option in treatment of non-infectious uveitis. However, few studies in the far easter region have concentrated on this therapy and current studies have not emphasized the elimination of retinal vasculitis. To compare the effectiveness of adalimumab (ADA) plus conventional therapy (CT) versus CT alone in treating patients with retinal vasculitis (RV) due to refractory Behçet's uveitis (BU).

DESIGN

Retrospective cohort study.

METHODS

Clinical records of BU patients with previously treated but poorly controlled RV were analyzed. Patients were allocated into two groups depending on ADA use. Each group was treated for no less than 6 months between February 2015 and September 2020. The primary outcome parameter was the RV score. Best-corrected visual acuity (BCVA), number of relapses, macular thickness and ocular complications were considered concomitantly.

RESULTS

Forty-two patients (72 eyes) were included; 21 patients were in CT group, and 21 patients were in ADA group. Inflammatory parameters improved in both groups. The improvement in the fluorescein angiography (FA) score and anterior chamber inflammation were significantly better in ADA group than in CT group (P < 0.05). The relapse time was significantly lower in ADA group than in CT group (P = 0.01). Daily glucocorticoid dose tapers were more evident in ADA group than in CT group (P < 0.05). Adverse events were detected in 7 patients (5 had upper respiratory tract infection and 2 had gastrointestinal discomfort) in ADA group; in CT group, upper respiratory infection and recurrent gum swelling were observed in 1 patient each.

CONCLUSION

Our results indicate that ADA plus CT outperforms CT alone in patients with RV due to refractory BU. More agile ADA use in these patients should be considered to achieve optimal treatment.

Is Real-World Evidence Used in P&T Monographs and Therapeutic Class Reviews?

BACKGROUND

Payers are faced with making coverage and reimbursement decisions based on the best available evidence. Often these decisions apply to patient populations, provider networks, and care settings not typically studied in clinical trials. Treatment effectiveness evidence is increasingly available from electronic health records, registries, and administrative claims. However, little is known about when and what types of real-world evidence (RWE) studies inform pharmacy and therapeutic (P&T) committee decisions.

OBJECTIVE

To evaluate evidence sources cited in P&T committee monographs and therapeutic class reviews and assess the design features and quality of cited RWE studies.

METHODS

A convenience sample of representatives from pharmacy benefit management, health system, and health plan organizations provided recent P&T monographs and therapeutic class reviews (or references from such documents). Two investigators examined and grouped references into major categories (published studies, unpublished studies, and other/unknown) and multiple subcategories (e.g., product label, clinical trials, RWE, systematic reviews). Cited comparative RWE was reviewed to assess design features (e.g., population, data source, comparators) and quality using the Good ReseArch for Comparative Effectiveness (GRACE) Checklist.

RESULTS

Investigators evaluated 565 references cited in 27 monographs/therapeutic class reviews from 6 managed care organizations. Therapeutic class reviews mostly cited published clinical trials (35.3%, 155/439), while single-product monographs relied most on manufacturer-supplied information (42.1%, 53/126). Published RWE comprised 4.8% (21/439) of therapeutic class review references, and none (0/126) of the monograph references. Of the 21 RWE studies, 12 were comparative and assessed patient care settings and outcomes typically not included in clinical trials (community ambulatory settings [10], long-term safety [8]). RWE studies most frequently were based on registry data (6), conducted in the United States (6), and funded by the pharmaceutical industry (5). GRACE Checklist ratings suggested the data and methods of these comparative RWE studies were of high quality.

CONCLUSIONS

RWE was infrequently cited in P&T materials, even among therapeutic class reviews where RWE is more readily available. Although few P&T materials cited RWE, the comparative RWE studies were generally high quality. More research is needed to understand when and what types of real-world studies can more routinely inform coverage and reimbursement decisions.

Use of biologic therapies for psoriasis during pregnancy and long-term outcomes of exposed children: A 14-year real-life experience at a tertiary center in Turkey and review of the literature

Data regarding the use of biologic therapies for psoriasis during pregnancy are scarce with even more limited knowledge about the long-term safety of in utero exposure. We retrospectively evaluated nine pregnancies in six women with psoriasis who were exposed to biologic therapies between 2006 and 2019 in our psoriasis clinic, a tertiary referral center in Turkey. Pregnancy outcomes included the delivery of seven healthy babies without any complications, one elective abortion, and one ectopic pregnancy. All exposed children, aged between 14 months and 13 years (median age: 4.0 years), showed normal growth and neuropsychological development without immunodeficiencies, allergies, malignancies or other diseases. Based on up-to-date collective data in the literature and our real-life clinical experience presented here, exposure to biologic therapies during pregnancy for psoriasis does not seem to be associated with adverse pregnancy or neonatal outcomes. Our results are also reassuring with respect to long-term outcomes of exposed children, but need to be confirmed through further large prospective studies. Nevertheless, use of biologic therapies during late pregnancy, particularly during the third trimester, should be reserved for high-need patients with psoriasis and definitely requires a delicate risk/benefit balance on a case-by-case basis.

Practical recommendations for systemic treatment in psoriasis in case of coexisting inflammatory, neurologic, infectious or malignant disorders (BETA-PSO: Belgian Evidence-based Treatment Advice in Psoriasis; part 2)

Background

Psoriasis patients carry an increased risk for associated comorbidities. Dermatologists have to be aware of the effects of systemic treatments not only on psoriasis but also on co‐occurring diseases. In case of other coexisting inflammatory diseases, the right psoriasis treatment may improve both disorders. For infectious and malignant disorders, some treatments have to be avoided as they may be harmful.

Objective

The primary objective of this project was to collect evidence for the creation of practice guidelines for systemic treatment of psoriasis (BETA‐PSO: Belgian Evidence‐based Treatment Advice in Psoriasis).

Methods

Evidence‐based recommendations were formulated using a quasi‐Delphi methodology after a systematic search of the literature and a consensus procedure involving eight psoriasis experts.

Results

Recommendations are given on the use of systemic treatment in psoriatic arthritis, inflammatory bowel disease, demyelinating disorders, hepatitis B and C, HIV and cancer.

Conclusion

This expert opinion is a practical guide for dermatologists when handling psoriasis patients with these specific conditions.

A controversial topic in juvenile idiopathic arthritis: Association between biologic agents and malignancy

OBJECTIVE

Over the last 2 decades, the usage of biological agents in the treatment of juvenile idiopathic arthritis (JIA) has been a successful and promising approach in controlling disease activity and preventing chronic sequelae. However, there are ongoing concerns about the long-term safety data and side-effect profile. We aimed to present preliminary data on the incidence of malignancy in patients with JIA treated with biological agents versus the general population rates in Turkey.

METHOD

A single-center hospital-based cohort study was performed to analyze cancer occurrence among JIA patients treated with biologic agents during the observation period between January 2004 and May 2019. As reference data for direct standardization, age, gender, and calendar year-specific incidence rates from the Turkish cancer registry were used. The standardized incidence ratio (SIR, ratio of cancers observed to expected) was generated with 95% confidence intervals.

RESULTS

The study sample consisted of 1023 JIA patients who had been treated with biologic or non-biologic agents. In the biologic-experienced group (n = 656), the mean age (at the study) was 16.7 ± 5.6 years. The mean length of follow-up was 9.9 ± 5.0 years. One cancer was detected within the observation period (SIR: 1.3, 95% CI: 0.06-6.3). The patient was an 18-year-old male who had previously received etanercept and tocilizumab until the diagnosis of the hematologic malignancy (SIR: 2.5, 95% CI: 0.1-12.6).

CONCLUSION

Patients treated with biologic agents appeared to have an increased rate of incident hematologic malignancy versus the general population in Turkey. However, before mentioning a clear causal relationship, other potential contributing factors should be taken into consideration.

Biologics in juvenile idiopathic arthritis-main advantages and major challenges: A narrative review

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. The disease is divided in different subtypes based on main clinical features and disease course. Emergence of biological agents targeting specific pro-inflammatory cytokines responsible for the disease pathogenesis represents the revolution in the JIA treatment. Discovery and widespread usage of biological agents have led to significant improvement in JIA patients’ treatment, with evidently increased functionality and decreased disease sequel. Increased risk of infections remains the main discussion topic for years. Despite the slightly increased frequency of upper respiratory tract infections reported in some studies, the general safety of drugs is acceptable with rare reports of severe adverse effects (SAEs). Tuberculosis (TBC) represents the important threat in regions with increased TBC prevalence. Therefore, routine screening for TBC should not be neglected when prescribing and during the follow-up of biological treatment. Malignancy represents a hypothetical complication that sometimes causes hesitations for physicians and patients in its prescription and usage. On the other hand, current reports from the literature do not support the increased risk for malignancy among JIA patients treated with biological agents. A multidisciplinary approach including a pediatric rheumatologist and an infectious disease specialist is mandatory in the follow- up of JIA patients. Although the efficacy and safety of biological agents have been proven in different studies, there is still a need for long-term, multicentric evaluation providing relevant data.

New Pharmacological Strategies for the Treatment of Non-Infectious Uveitis. A Minireview

Non-infectious uveitis (NIU) is a group of disorders characterized by intraocular inflammation at different levels of the eye. NIU is a leading cause of irreversible blindness in working-age population in the developed world. The goal of uveitis treatment is to control inflammation, prevent recurrences, and preserve vision, as well as minimize the adverse effects of medications. Currently, the standard of care for NIU includes the administration of corticosteroids (CS) as first-line agents, but in some cases a more aggressive therapy is required. This includes synthetic immunosuppressants, such as antimetabolites (methotrexate, mycophenolate mofetil, and azathioprine), calcineurinic inhibitors (cyclosporine, tacrolimus), and alkylating agents (cyclophosphamide, chlorambucil). In those patients who become intolerant or refractory to CS and conventional immunosuppressive treatment, biologic agents have arisen as an effective therapy. Among the most evaluated treatments, TNF-α inhibitors, IL blockers, and anti-CD20 therapy have emerged. In this regard, anti-TNF agents (infliximab and adalimumab) have shown the strongest results in terms of favorable outcomes. In this review, we discuss latest evidence concerning to the effectiveness of biologic therapy, and present new therapeutic approaches directed against immune components as potential novel therapies for NIU.

New therapies in development for the management of non-infectious uveitis: A review

Uveitis is a spectrum of inflammatory disorders characterized by ocular inflammation and is one of the leading causes of preventable visual loss. The main aim of the treatment of uveitis is to control the inflammation, prevent recurrences of the disease and preserve vision while minimizing the adverse effects associated with the therapeutic agents. Initial management of uveitis relies heavily on the use of corticosteroids. However, monotherapy with high-dose corticosteroids is associated with side effects and cannot be maintained long term. Therefore, steroid-sparing agents are needed to decrease the burden of steroid therapy. Currently, the therapeutic approach for non-infectious uveitis (NIU) consists of a step-ladder strategy with the first-line option being corticosteroids in various formulations followed by the use of first-, second- and third-line agents in cases with suboptimal steroid response. Unfortunately, the agents currently at our disposal have limitations such as having a narrow therapeutic window along with their own individual potential side-effect profiles. Therefore, research has been targeted to identify newer drugs as well as new uses for older drugs that target specific pathways in the inflammatory response. Such efforts are made in order to provide targeted and safer therapy with reduced side effects and greater efficacy. Several specially designed molecular antibodies are currently in various phases of investigations that can potentially halt the inflammation in patients with NIU. In the review, we have provided a comprehensive overview of the current and upcoming therapeutic options for patients with NIU.

Cancer Risk in Pediatric-Onset Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a chronic, immune-mediated, non-curable disease. The incidence of IBD appears to have risen over the last few decades especially in the pediatric age group. IBD usually presents with gastrointestinal symptoms, including abdominal pain, diarrhea, and bleeding per rectum but can also be associated with systemic symptoms such as weight loss, fatigue, joint and skin problems, and psychological comorbidities. One major complication is gastrointestinal and extra-intestinal malignancy. This review discusses literature that focuses on cancer risk of pediatric-onset IBD.

Safety of systemic therapy for noninfectious uveitis

Introduction: The treatment strategies for noninfectious uveitis (NIU) aim to achieve disease remission, prevention of recurrences, and preserving vision, while minimizing the side effects associated with the therapies used.Areas covered: The index review aims to provide a detailed overview of the adverse events and safety parameters associated with the systemic therapies for the management of the NIU.Expert opinion: Despite being the cornerstone of management of acute cases of NIU, long-term corticosteroid use is associated with multi-system side effects, requiring the use of steroid-sparing agents. Adalimumab was recently approved by the FDA for the management of NIU based on the results of VISUAL studies. Similarly, newer drugs targeting various aspects of the inflammatory cascade are being developed. However, until we completely understand the molecular pathways of the inflammatory diseases, the therapeutic profile of these newer agents needs to be broad enough to suppress inflammatory cascade and narrow enough to spare normal cellular processes. Another strategy that has shown some potential in decreasing the systemic side effects is to provide local drug delivery. Therefore, the future of management of NIU is very bright with many novel therapeutic agents and strategies of drug delivery on the horizon.

Assessment of the real-world safety profile of vedolizumab using the United States Food and Drug Administration adverse event reporting system

Vedolizumab is the first gut-selective integrin blocker indicated for patients with Crohn's disease (CD) and ulcerative colitis (UC). This study aimed to examine the adverse events (AEs) profile of vedolizumab compared to anti-tumor necrosis factors (anti-TNFs) indicated for CD and UC using the FDA Adverse Event Reporting System (FAERS) database. AE reports with vedolizumab (5/20/2014-6/30/2015) and CD/UC-indicated anti-TNF drugs (adalimumab, infliximab, certolizumab pegol, and golimumab, during 8/1/1998-6/30/2015) as primary suspects were extracted from the FAERS database. AEs associated with vedolizumab were compared for signals of disproportionate reporting against anti-TNF drugs and all other drugs (1969-6/30/2015), using the proportional reporting ratio (PRR) and the empirical Bayesian geometric mean (EBGM) algorithms. The search retrieved 499 reports for vedolizumab and 119,620 reports for anti-TNFs, with 35.9% and 32.1% of these, respectively, being serious AEs. With the PRR approach, vedolizumab-associated reports had signals for 22 groups of AEs (9 were associated with serious outcomes) relative to anti-TNFs and had 34 signals relative to all other drugs. Signals detected included those reported as warnings in prescribing information and new AEs related to cardiovascular disease. Due to the voluntary nature of FAERS, this finding should be considered hypothesis generating (rather than hypothesis testing). Longer-term observational studies are required to evaluate the safety of vedolizumab.

Juvenile idiopathic arthritis and risk of cancer before and after the introduction of biological therapies

Background

The risk of cancer, including any secular trends in risk, in patients with juvenile idiopathic arthritis (JIA) is incompletely understood.

Methods

We performed a register-based cohort study of patients with JIA from 2001 until 2017, identified via the Swedish Patient Register. Patients with JIA were matched to five population reference subjects. Patients and referents were followed up for incident cancers (via linkage to the Swedish Cancer Register) until 18 years of age or 31 December 2016.

Results

Among the 6721 patients with JIA, we observed 10 incident malignancies (5 lymphoproliferative cancers) during 34 951 person-years of follow-up, corresponding to an excess incidence of 0.09 cancers per 1000 person-years (one extra case per 11 000 patients per year), an HR for cancer (all sites) of 1.4 (95% CI 0.7 to 2.9) and an HR for lymphoproliferative malignancies of 3.6 (95% CI 1.1 to 11.2). The rates of cancer in JIA did not increase over the study period. We noted no differences in the excess risk comparing periods before and after the introduction of biologic disease-modifying antirheumatic drugs (bDMARDs).

Discussion

Children and adolescents with JIA are at a slightly increased risk of lymphoproliferative (but not of other) malignancies. At the group level, there is no sign that this risk has increased further after the introduction of bDMARDs.

The Efficacy and Evidence-Based Use of Biologics in Children and Adolescents: Using Monoclonal Antibodies and Fusion Proteins as Treatments

BACKGROUND

Monoclonal antibodies (mAb) and fusion proteins (FP) are increasingly being used in children and adolescents. In this review, we analyze the evidence for their safety and efficacy in the treatment of the most common chronic inflammatory diseases.

METHODS

We systematically searched PubMed, AWMF.org, and other databases for high-quality trials (i.e., randomized controlled trials with clinical primary endpoints) and guidelines published at any time up to 10 December 2018 that dealt with mAb and FP that are approved for pediatric use. The search term was "monoclonal anti- body/fusion protein [e. g. adalimumab] AND children."

RESULTS

The 620 hits included 25 high-quality trials (20 of them manufacturer- sponsored) on 9 mAb/FP (omalizumab, adalimumab, etanercept, ustekinumab, infliximab, golimumab, anakinra, canakinumab, tocilizumab, and abatacept), as well as 6 guidelines (3 each of levels S3 and S2k) on the treatment of bronchial asthma, psoriasis, juvenile idopathic arthritis, and chronic inflammatory bowel diseases. For none of these conditions are mAb and FP the drugs of first choice. Adverse drug effects are rare but sometimes severe (infection, immune dysregulation, tumors).

CONCLUSION

The retrieved trials have deficiencies that make it difficult to reliably evaluate the efficacy, safety, and utility of mAb/FP for children and adolescents with chronic inflammatory diseases. mAb/FP nonetheless represent a treatment option to be considered in case conventional immune-modulating drugs are ineffective. Researcher-initiated, high-quality trials and manufacturer-independent, systematic long-term evaluations of adverse effects (e.g., tumors) are sorely needed.

Anticipatory care of children and adolescents with inflammatory bowel disease: a primer for primary care providers

PURPOSE OF REVIEW

About 10-20% of patients with newly diagnosed inflammatory bowel disease (IBD) are under 18 years of age, with incidence increasing in young children. Children with IBD have unique healthcare needs, which require coordination between primary care providers and pediatric gastroenterologists to provide appropriate care. This review highlights some key elements of anticipatory care in pediatric IBD, including vaccination, risk of serious infection and malignancy, psychosocial and educational needs, and cannabis use.

RECENT FINDINGS

Therapies for IBD that include anti-tumor necrosis factor medications, especially when combined with corticosteroids are associated with higher risks of serious infections. Vaccination remains the best way to prevent infections. Live vaccinations should be avoided during immunosuppression, but the schedule should be otherwise completed, including vaccination for influenza, pneumococcus and meningococcus, and human papillomavirus. Malignancy risk is increased in IBD patients, both because of disease factors and resulting from immunomodulatory medications. Children with IBD are at risk for mental health disorders and negative educational outcomes, so identification of at-risk children and early intervention are important.

SUMMARY

High-quality care in pediatric IBD requires coordination between pediatric gastroenterologists and primary care providers, with careful attention paid to the specific needs of children with IBD.

The Top 100 Highly Cited Original Articles on Immunotherapy for Childhood Leukemia

Background: Childhood leukemia is one of the most common cancers in children. As a potential treatment for leukemia, immunotherapy has become a new research hotspot. This research aimed at exploring the status and trends of current researches on immunotherapy for childhood leukemia through bibliometric analysis.

Methods: The Institute for Scientific Information Web of Science core collection database was searched for articles on immunotherapy and childhood leukemia using a computer. Time period for retrieval was from the beginning of the database to June 15, 2019. The top 100 highly cited articles were selected to extract their information on publication year, authors, title, publication journal, number of citations, author’s affiliations, country, and so on. These general information and bibliometric data were collected for analysis. VOSviewer software was used to generate a figure for keywords’ co-occurrence network and a figure for researcher’s coauthorship network that visualized reference and cooperation patterns for different terms in the 100 articles.

Results: The number of citations in the top 100 articles ranged from 17 to 471. These articles were published in 52 different publications. The top four journals in terms of the number of our selected articles were Leukemia (11 articles), Blood (10 articles), Bone Marrow Transplantation (6 articles), and Clinical Cancer Research. The most frequently nominated author was T. Klingebiel from Goethe University Frankfurt, and of the top 100 articles, 12 listed his name. These top 100 articles were published after the year 2000. Most of these articles were original (67%). The United States and Germany were the major countries researching immunotherapy for childhood leukemia and made significant contributions to the combat against the disease. Adoptive immunotherapy and stem cell transplantation appeared more frequently in keywords.

Conclusions: This study analyzed the top 100 highly cited articles on immunotherapy for childhood leukemia and provided insights into the features and research hotspots of the articles on this issue.

Biologic Treatment Options for Pediatric Psoriasis and Atopic Dermatitis

Background and Objectives: Severe, recalcitrant cases of pediatric psoriasis or atopic dermatitis may necessitate treatment with biological agents; however, this may be difficult due to lack of treatment options and standardized treatment guidelines. This review evaluates the biological treatment options available, including off-label uses, and provides a basic therapeutic guideline for pediatric psoriasis and atopic dermatitis. Materials and Methods: A PubMed review of biological treatments for pediatric psoriasis and atopic dermatitis with information regarding age, efficacy, dosing, contra-indications, adverse events, and off-label treatments. Results: Currently there are three European Medicines Agency (EMA)-approved biological treatment options for pediatric psoriasis: etanercept, ustekinumab, and adalimumab. While dupilumab was recently Food and Drug Administration (FDA)- and EMA-approved for adult atopic dermatitis, it is still not yet approved for pediatric atopic dermatitis. Conclusions: Given the high morbidity associated with pediatric atopic dermatitis and psoriasis, there is a need for more treatment options. Further research and post-marketing registries are needed to extend the use of biologics into pediatric patients.

Shared decision making in IBD: A novel approach to trial consent and timing

Background

Shared decision making (SDM) between families and physicians may facilitate informed, timely decisions to proceed with biologic therapy in children with inflammatory bowel disease (IBD). Our team previously developed an SDM tool to aid communication between physicians and families when considering biologic therapy for children with IBD.

Objective

We are conducting a prospective, pre-post pilot trial of a new SDM tool. The primary aim of the study is to assess feasibility of both the intervention and trial procedures for a future large-scale trial.

Methods

We are enrolling physicians with experience prescribing biologic therapy in the past year and families of children with IBD. Families in the intervention arm receive a 3-step intervention including a letter sent before trial consent or clinic appointment, an in-clinic decision tool and a follow-up phone call. Our primary trial outcome is a measure of feasibility, with measures of clinical and decision outcomes secondary. We seek to enroll 27 families in each of 2 arms (usual-care and intervention) and plan data collection at the time of the initial visit or hospital stay, and at 1 week, 3 months, and 6 months after the initial visit.

Conclusion

This study protocol is designed to demonstrate that integrating novel consent procedures, including timing and multiple versions of written consent, may increase trial feasibility while maintaining scientific rigor and full protection of study participants.

Malignant transformation of neurocutaneous melanosis (NCM) following immunosuppression

Neurocutaneous melanosis (NCM) is the condition of abnormal melanocyte deposition in the leptomeninges and brain parenchyma. Associated with congenital melanocytic nevi, NCM can result in neurologic deficits, hydrocephalus, and rarely, malignant transformation of cells. We present the case of a 16-year-old boy with NCM who developed malignant leptomeningeal melanoma following immunosuppression with a TNFα inhibitor. To our knowledge, this is the first reported case of a patient with known NCM undergoing malignant transformation after anti-TNF therapy for inflammatory bowel disease.

Etanercept treatment for extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, or psoriatic arthritis: 6-year efficacy and safety data from an open-label trial

BACKGROUND

To describe the 6-year safety and efficacy of etanercept (ETN) in children with extended oligoarticular juvenile idiopathic arthritis (eoJIA), enthesitis-related arthritis (ERA), and psoriatic arthritis (PsA) METHODS: Patients who completed the 2-year, open-label, phase III CLinical Study In Pediatric Patients of Etanercept for Treatment of ERA, PsA, and Extended Oligoarthritis (CLIPPER) were allowed to enroll in its 8-year long-term extension (CLIPPER2). Children received ETN at a once-weekly dose of 0.8 mg/kg, up to a maximum dose of 50 mg/week. Efficacy assessments included the JIA core set of outcomes, the JIA American College of Rheumatology response criteria (JIA-ACR), and the Juvenile Arthritis Disease Activity Score (JADAS). Efficacy data are reported as responder analyses using a hybrid method for missing data imputation and as observed cases. Safety assessments included treatment-emergent adverse events (TEAEs).

RESULTS

Out of 127 patients originally enrolled in CLIPPER, 109 (86%) entered CLIPPER2. After 6 years of trial participation (2 years in CLIPPER and 4 years in CLIPPER2), 41 (32%) patients were still taking ETN, 13 (11%) entered the treatment withdrawal phase after achieving low/inactive disease (of whom 7 had to restart ETN), 36 (28%) discontinued treatment for other reasons but are still being observed, and 37 (29%) discontinued treatment permanently. According to the hybrid imputation analysis, proportions of patients achieving JIA ACR90, JIA ACR100, and JADAS inactive disease after the initial 2 years of treatment were 58%, 48%, and 32%, respectively. After the additional 4 years, those proportions in patients who remained in the trial were 46%, 35%, and 24%. Most frequently reported TEAEs [n (%), events per 100 patient-years] were headache [28 (22%), 5.3], arthralgia [24 (19%), 4.6], and pyrexia [20 (16%), 3.8]. Number and frequency of TEAEs, excluding infections and injection site reactions, decreased over the 6-year period from 193 and 173.8, respectively, during year 1 to 37 and 61.3 during year 6. A single case of malignancy (Hodgkin's lymphoma) and no cases of active tuberculosis, demyelinating disorders, or deaths were reported.

CONCLUSIONS

Open-label etanercept treatment for up to 6 years was safe, well tolerated, and effective in patients with eoJIA, ERA, and PsA.

A case of recalcitrant pediatric Vogt-Koyanagi-Harada disease successfully controlled with adalimumab

Vogt-Koyanagi-Harada (VKH) disease is uncommon in the pediatric population and can have an aggressive course with serious visual sequelae. A 12-year-old Han Chinese American female, who presented with mild headaches and panuveitis with diffuse serous retinal detachments, was diagnosed with VKH. Despite treatment with a combination of high-dose systemic corticosteroids, intravitreal triamcinolone injection, and mycophenolate mofetil, ocular inflammation was inadequately controlled. Addition of adalimumab allowed for inflammation remission, improvement of vision, and tapering of systemic corticosteroids. Escalation of immunosuppression until remission appears to be critical in this population. Further research is needed to understand the complex pathophysiology of VKH and investigation for similar efficacy of other anti-tumor necrosis factor-alpha agents will need to be performed.

Pharmacovigilance in juvenile idiopathic arthritis patients treated with biologic or synthetic drugs: combined data of more than 15,000 patients from Pharmachild and national registries

BACKGROUND

The availability of methotrexate and the introduction of multiple biological agents have revolutionized the treatment of juvenile idiopathic arthritis (JIA). Several international and national drug registries have been implemented to accurately monitor the long-term safety/efficacy of these agents. This report aims to present the combined data coming from Pharmachild/PRINTO registry and the national registries from Germany (BiKeR) and Sweden.

METHODS

Descriptive statistics was used for demographic, clinical data, drug exposure, adverse events (AEs) and events of special interest (ESIs). For the Swedish register, AE data were not available.

RESULTS

Data from a total of 15,284 patients were reported: 8274 (54%) from the Pharmachild registry and 3990 (26%) and 3020 (20%) from the German and the Swedish registries, respectively. Pharmachild children showed a younger age (median of 5.4 versus 7.6 years) at JIA onset and shorter disease duration at last available visit (5.3 versus 6.1-6.8) when compared with the other registries. The most frequent JIA category was the rheumatoid factor-negative polyarthritis (range of 24.6-29.9%). Methotrexate (61-84%) and etanercept (24%-61.8%) were the most frequently used synthetic and biologic disease-modifying anti-rheumatic drugs (DMARDs), respectively. There was a wide variability in glucocorticoid use (16.7-42.1%). Serious AEs were present in 572 (6.9%) patients in Pharmachild versus 297 (7.4%) in BiKeR. Infection and infestations were the most frequent AEs (29.4-30.1%) followed by gastrointestinal disorders (11.5-19.6%). The most frequent ESIs were infections (75.3-89%).

CONCLUSIONS

This article is the first attempt to present a very large sample of data on JIA patients from different national and international registries and represents the first proposal for data merging as the most powerful tool for future analysis of safety and effectiveness of immunosuppressive therapies in JIA.

REGISTRY REGISTRATION

The Pharmachild registry is registered at ClinicalTrials.gov ( NCT01399281 ) and at the European Network of Centres for Pharmacoepidemiology and Pharmacovigilance (ENCePP) ( http://www.encepp.eu/encepp/viewResource.htm?id=19362 ).

Risks associated with use of TNF inhibitors in children with rheumatic diseases

Introduction: Tumor necrosis factor alpha (TNF-α) is a pro-inflammatory cytokine involved in the pathogenesis of many inflammatory diseases. Several drugs blocking TNF-α are employed in clinical practice in pediatrics. Given their action on the immune system, TNF-α inhibitors have raised concerns on their safety profile since their introduction. A broad spectrum of side effects related to TNF inhibition has been reported: immunogenicity, infectious diseases, malignancies, and others. Areas covered: In order to assess the risk related to the use of anti-TNF-α agents in children with rheumatic diseases we analyzed data obtained from retrospective and prospective safety studies, case reports and case series, and controlled trials. Expert commentary: Anti-TNF-α agents have shown a remarkably good safety profile in the pediatric population so far. However, there are lots of questions to be answered and maintaining active surveillance on these drugs is necessary in order to not overlook any possible unexpected adverse effects.

Bone tumors developed in patients with juvenile inflammatory arthritis after anti-TNFα therapy

Administration of anti-TNFα agents has become a mainstay in the treatment of chronic inflammatory arthritis such as rheumatoid arthritis (RA) and spondyloarthritis. Adverse events, including infections and allergic reactions, have been reported. Malignancies are rare but potentially life threatening. The existence of bone tumor in those patients is very rare, only five cases of bone tumors were mentioned in juvenile idiopathic arthritis (JIA) in the literature. We describe three patients in whom bone neoplasms developed after years of anti-TNFα therapy for JIA or juvenile ankylosing spondylitis (JAS). One patient developed chondroblastoma, and the other two were diagnosed with osteosarcoma. Rheumatologists should increase their awareness of bone neoplasia in JIA or juvenile ankylosing spondylitis patients after anti-TNFα treatment.

Malignancy and mortality in paediatric-onset inflammatory bowel disease: a 3-year prospective, multinational study from the paediatric IBD Porto group of ESPGHAN

BACKGROUND

Risk benefit strategies in managing inflammatory bowel diseases (IBD) are dependent upon understanding the risks of uncontrolled inflammation vs those of treatments. Malignancy and mortality in IBD have been associated with disease-related inflammation and immune suppression, but data are limited due to their rare occurrence.

AIM

To identify and describe the most common causes of mortality, types of cancer and previous or current therapy among children and young adults with paediatric-onset IBD.

METHODS

Information on paediatric-onset IBD patients diagnosed with malignancy or mortality was prospectively collected via a survey in 25 countries over a 42-month period. Patients were included if death or malignancy occurred after IBD diagnosis but before the age of 26 years.

RESULTS

In total, 60 patients were identified including 43 malignancies and 26 fatal cases (9 due to cancer). Main causes of fatality were malignancies (n = 9), IBD or IBD-therapy related nonmalignant causes (n = 10; including 5 infections), and suicides (n = 3). Three cases, all fatal, of hepatosplenic T-cell lymphoma were identified, all were biologic-naïve but thiopurine-exposed. No other haematological malignancies were fatal. The 6 other fatal cancer cases included 3 colorectal adenocarcinomas and 3 cholangiocarcinomas (CCAs). Primary sclerosing cholangitis (PSC) was present in 5 (56%) fatal cancers (1 colorectal carcinoma, 3 CCAs and 1 hepatosplenic T-cell lymphoma).

CONCLUSIONS

We report the largest number of paediatric-onset IBD patients with cancer and/or fatal outcomes to date. Malignancies followed by infections were the major causes of mortality. We identified PSC as a significant risk factor for cancer-associated mortality. Disease-related adenocarcinomas were a commoner cause of death than lymphomas.

Complications of Treatments for Pediatric Rheumatic Diseases

Medications to treat children with rheumatic disease include disease-modifying antirheumatic drugs, glucocorticosteroids, and biologic response modifiers that target mediators and cells involved in autoimmunity and inflammation. Although usually well-tolerated, such medications have many possible side effects, of which primary care and emergency providers should be aware. Both disease and immunosuppression contribute to susceptibility to unusual and opportunistic infections, in addition to usual childhood infections for which these children should receive all applicable nonlive vaccines. Close coordination between the rheumatologist and other medical care providers is essential, because medication side effects, infections, and disease flares are difficult to distinguish, and may occur together.

Juvenile Idiopathic Arthritis

Juvenile idiopathic arthritis is the most common chronic rheumatic disease of unknown aetiology in childhood and predominantly presents with peripheral arthritis. The disease is divided into several subgroups, according to demographic characteristics, clinical features, treatment modalities and disease prognosis. Systemic juvenile idiopathic arthritis, which is one of the most frequent disease subtypes, is characterized by recurrent fever and rash. Oligoarticular juvenile idiopathic arthritis, common among young female patients, is usually accompanied by anti-nuclear antibodie positivity and anterior uveitis. Seropositive polyarticular juvenile idiopathic arthritis, an analogue of adult rheumatoid arthritis, is seen in less than 10% of paediatric patients. Seronegative polyarticular juvenile idiopathic arthritis, an entity more specific for childhood, appears with widespread large- and small-joint involvement. Enthesitis-related arthritis is a separate disease subtype, characterized by enthesitis and asymmetric lower-extremity arthritis. This disease subtype represents the childhood form of adult spondyloarthropathies, with human leukocyte antigen-B27 positivity and uveitis but commonly without axial skeleton involvement. Juvenile psoriatic arthritis is characterized by a psoriatic rash, accompanied by arthritis, nail pitting and dactylitis. Disease complications can vary from growth retardation and osteoporosis secondary to treatment and disease activity, to life-threatening macrophage activation syndrome with multi-organ insufficiency. With the advent of new therapeutics over the past 15 years, there has been a marked improvement in juvenile idiopathic arthritis treatment and long-term outcome, without any sequelae. The treatment of juvenile idiopathic arthritis patients involves teamwork, including an experienced paediatric rheumatologist, an ophthalmologist, an orthopaedist, a paediatric psychiatrist and a physiotherapist. The primary goals of treatment are to eliminate active disease, to normalize joint function, to preserve normal growth and to prevent long-term joint damage. Timely and aggressive treatment is important to provide early disease control. The first-line treatment includes disease-modifying anti-rheumatic drugs (methotrexate, sulphasalazine, leflunomide) in combination with corticosteroids, used in different dosages and routes (oral, intravenous, intra-articular). Intra-articular application of steroids seems to be an effective treatment modality, especially in monoarthritis. Biological agents should be added in the treatment of unresponsive patients. Anti-tumour necrosis factor agents (etanercept, infliximab, adalimumab), anti-interleukin-1 agents (anakinra, canakinumab), anti- interleukin-6 agents (tocilizumab) and T-cell regulatory agents (abatacept) have been shown to be safe and effective in childhood patients. Recent studies reported sustained reduction in joint damage with even complete clinical improvement in paediatric patients, compared to previous data.

The Use and Safety of TNF Inhibitors during Pregnancy in Women with Psoriasis: A Review

Psoriasis is a chronic immune-mediated inflammatory disease affecting women of childbearing potential. Biologic agents, notably Tumor Necrosis Factor inhibitors (TNFi), are the only current non-contraindicated systemic treatment option during pregnancy. TNFi comprised of complete immunoglobulin G (IgG) antibodies antibodies (adalimumab, golimumab, and infliximab) actively cross the placenta from the second trimester and are detectable in the child up to one year postpartum. Data on safety of TNFi are conflicting; however a trend towards drug-specific harm has been reported, with increased risk of congenital malformations and preterm birth. TNFi exposure may alter the immune system of the infant towards hypersensitivity and reduced response to intracellular infections. Confounding by indication should be considered, as chronic inflammatory disease itself may pose a risk of adverse pregnancy outcomes. The quality of the current evidence is very low and no studies specifically address TNFi safety in women with psoriasis. Nonetheless, risks associated with TNFi treatment must be balanced against the as-yet uncertain risk of adverse outcomes in infants born to women with severe psoriasis. We searched PubMed using Medical Subject Headings (MeSH) terms and identified relevant studies and guidelines. Herein, we present the current knowledge of the use and safety of TNFi during pregnancy in women with psoriasis.

Serious Adverse Events Associated with Anti-Tumor Necrosis Factor Alpha Agents in Pediatric-Onset Inflammatory Bowel Disease and Juvenile Idiopathic Arthritis in A Real-Life Setting

OBJECTIVES

Anti-tumor necrosis factor alpha (anti-TNF-α) agents are generally well tolerated, yet they can be associated with serious adverse events (SAEs) in a minority of patients. We examined the incidence of SAEs in a pediatric referral center for chronic rheumatologic and gastroenterological inflammatory disorders.

METHODS

Retrospective analysis of SAEs occurring during treatment with anti-TNF-α agents in patients with juvenile idiopathic arthritis (JIA) (n = 78)  or pediatric-onset inflammatory bowel disease (IBD) (n = 105) seen at the Institute for Maternal and Child Health IRCCS "Burlo Garofolo" in Trieste, Italy, between June 2001 and February 2016. Only SAEs grade 3-5 according to the Common Terminology Criteria for Adverse Events version 4.03 and/or requiring definitive therapy discontinuation were reported.

RESULTS

Total anti-TNF-α exposure was 390.5 patient-years (PYs). The overall incidence rate of SAEs for etanercept was 4.14/100 PYs. Four patients developed uveitis, two had anxiety disorders, one had a serious zoster infection, and one developed TNF-α antagonist-induced lupus-like syndrome (TAILS). The overall incidence rate of SAEs for infliximab was 22.49/100 PYs. The most common SAEs were anaphylactoid reactions (n = 18), followed by infectious events (n = 9) and TAILS (n = 3). The overall incidence rate of SAEs for adalimumab was 4.71/100 PYs (two infectious SAEs). No malignancies or deaths were observed. A greater incidence rate of infectious SAEs was observed in IBD patients receiving infliximab compared to JIA patients receiving etanercept (8.11 vs 0.52 per 100 PYs).

CONCLUSIONS

Anti-TNF-α therapy was generally well tolerated. SAEs leading to anti-TNF-α discontinuation were rare and non-fatal. Infliximab was associated with the highest incidence of SAEs. Infectious SAEs were more frequently observed in IBD patients treated with infliximab than in JIA patients receiving etanercept.

Malignancy and Mortality in Pediatric-onset Inflammatory Bowel Disease: A Systematic Review

BACKGROUND

Cancer and death are the most severe outcomes that affect patients with inflammatory bowel disease (IBD). These outcomes are even more severe if they occur at a young age but are rare, even in the general population. We conducted a systematic review to provide an overview of all reported pediatric (PIBD) patients with severe outcome.

METHODS

A literature search identified publications that reported development of cancer or fatal outcome in PIBD patients. Studies were eligible for inclusion when (1) article written in English, (2) original data, (3) individual patient information, (4) full text available, (5) study population consisting of patients diagnosed with IBD under the age of 19 years, and (6) who developed malignancy or fatality at any point later in life.

RESULTS

A total of 98 included studies comprised data of 271 PIBD patients who developed cancer and/or fatal outcome at any point later in life. Meta-analysis demonstrated an increased risk for cancer in PIBD patients (pooled standardized incidence ratio 2.23, 95% CI: 1.98-2.52). The most frequent type of non-fatal cancer was lymphoma, whereas colorectal carcinomas were the most frequently reported type of fatal cancer in PIBD patients and were particularly associated with primary sclerosing cholangitis. The majority of patients with noncancer-related fatal outcomes were diagnosed with ulcerative colitis and most often died due to infectious complications or severe disease-associated complications.

CONCLUSIONS

The data in this review confirm that PIBD associated malignancy and mortality are rare and detailed clinical characteristics are limited. Prospective and international collaborations are needed to obtain more detailed patient-specific information, which is necessary to investigate the relationship between severe outcomes in PIBD patients and the currently used therapeutic strategies. 10.1093/ibd/izx104_video1izx104_Video5754026434001.

Development of neoplasms in pediatric patients with rheumatic disease exposed to anti-tumor necrosis factor therapies: a single Centre retrospective study

BACKGROUND

Anti-TNF (Tumor necrosis factor) therapy is effective in treating pediatric patients with refractory rheumatic disease. There is however a concern that anti-TNF usage may increase the risk of malignancy. Reports on specific types of malignancy in this patient population have been emerging over the past decade, but there is a need for additional malignancy reports, as these events are rare. Therefore, a retrospective chart review was performed on the biologic database of pediatric rheumatology patients at The Hospital for Sick Children (SickKids) from 1997 to 2013 for neoplasms, patient demographic information and rheumatologic treatment course.

FINDINGS

6/357 (1.68%) rheumatology patients treated with anti-TNF therapy between 1997 and 2013 developed neoplasms. One patient had two malignancies. One patient had a benign neoplasm. Cases were exposed to etanercept, infliximab or both. Neoplasms developed late after anti-TNF exposure (median 5.0 years) and infliximab treatment was associated with a shorter time to malignancy. The neoplasms identified were as follows: 2 renal clear cell carcinoma, 1 pilomatricoma, 1 nasopharyngeal carcinoma, 1 Ewing's sarcoma, 1 hepatic T-cell lymphoma, 1 lymphoproliferative disease.

CONCLUSIONS

The malignancy rate at our centre is low, however more than half of the neoplasms identified were rare and unusual in the pediatric population. The 5-year malignancy-free probability for patients with juvenile idiopathic arthritis (JIA) treated with biologic therapy was 97% from our database. Long-term screening for rare neoplasms is important as part of the safety monitoring for any pediatric rheumatology patient receiving anti-TNF therapy.
