Rare and severe adverse events in children with inflammatory bowel disease: analysis of data from the PIBD-SETQuality Safety Registry. THE LANCET. CHILD & ADOLESCENT HEALTH 2024; 8:422-432. [PMID: 38697175 DOI: 10.1016/s2352-4642(24)00078-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 03/21/2024] [Accepted: 03/22/2024] [Indexed: 05/04/2024]
Abstract
BACKGROUND Rare and severe adverse events can occur in children with inflammatory bowel disease (IBD), and the relationship with disease or drug treatment is often uncertain. We aimed to establish a method of reporting adverse events of interest in children with IBD, allowing for estimates of incidence rates with comparison between different regions, and, if possible, to compare with published data on rates of adverse events in children overall. METHODS For this analysis, we used data from the Paediatric Inflammatory Bowel Disease Network for Safety, Efficacy and Treatment and Quality improvement of care (PIBD-SETQuality) Safety Registry, which collects data on multiple rare and severe adverse events in children younger than 19 years with IBD. Overall, the registry collected data on ten prespecified rare and severe adverse events in children with IBD, as established by a panel of paediatric IBD experts, via reports from paediatric gastroenterologists at participating hospitals between Nov 1, 2016, and March 31, 2023. Reporting physicians, who could only be paediatric gastroenterologists or IBD nurses reporting on behalf of paediatric gastroenterologists, were recruited through invitations sent to both national and international IBD networks and at conferences. Once per month, participating paediatric gastroenterologists received an email with an anonymous and unique link to an online survey asking them to report whether any of ten rare and severe adverse events had occurred in a patient in their paediatric-IBD population in the previous month. Prevalent or retrospective rare and severe adverse events were excluded, as were events occurring in children with an unconfirmed diagnosis of IBD or for whom inflammatory colitis was part of a monogenic immunodeficiency disorder. Duplicates and events that did not meet the definitions and criteria were excluded. Physicians could also report other, non-categorised adverse events if they considered them rare and severe. In case of no response, up to two reminders were sent for each per-month survey. Annual denominator data surveys were sent to obtain the total number of person-years for the estimation of incidence rates, which were calculated via Poisson regression models. FINDINGS Responses were gathered from 220 paediatric gastroenterologists from 167 centres. 121 centres were in Europe, 23 centres were in North America, 17 centres were in Asia, and six centres were in Oceania. Combined, the total population with paediatric IBD consisted of an estimated 30 193 children with 114 528 person-years of follow-up. 451 adverse events were initially reported. After excluding and reorganising adverse events, 402 were eligible; 261 (65%) were categorised and 141 (35%) were non-categorised. The most frequently reported adverse events were venous-thromboembolic events (n=66), renal failure (n=43), opportunistic infections (n=42), and cancer (n=33). Haemophagocytic lymphohistiocytosis (n=4) and liver failure (n=3) were the least frequently reported adverse events. Incidence rates per 10 000 person-years were 5·50 (95% CI 4·25-6·97) for venous-thromboembolic events, 3·75 (2·74-4·99) for renal failure, 3·67 (2·67-4·89) for opportunistic infection, and 2·88 (2·01-3·98) for cancer. Of 66 venous-thromboembolic events, 31 (47%) involved cerebral venous sinus thrombosis at an incidence rate of 2·71 (95% CI 1·86-3·77). INTERPRETATION The PIBD-SETQuality Safety Registry enabled us to identify incidence rates of rare and severe adverse events in children with IBD. Our findings can guide physicians and enhance awareness of the incidence of adverse events in children with IBD that are considered to be rare.

Illustrated State-of-the-Art Capsules of the ISTH 2024 Congress. Res Pract Thromb Haemost 2024; 8:102432. [PMID: 38854821 PMCID: PMC11157278 DOI: 10.1016/j.rpth.2024.102432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2024] [Accepted: 04/26/2024] [Indexed: 06/11/2024] Open
Abstract
Here, we present a series of illustrated capsules from the State of the Art (SOA) speakers at the 2024 International Society on Thrombosis and Haemostasis Congress in Bangkok, Thailand. This year's Congress marks the first time that the International Society on Thrombosis and Haemostasis has held its flagship scientific meeting in Southeast Asia and is the first to be organized by an international Planning Committee. The Bangkok program will feature innovative science and clinical updates from around the world, reflecting the diversity and multidisciplinary growth of our field. In these illustrated SOA capsules, you will find an exploration of novel models of thrombosis and bleeding and biomaterial discoveries that can trigger or block coagulation. Thromboinflammation is now understood to drive many disease states, and the SOA speakers cover cellular and coagulation responses to COVID-19 and other infections. The theme of crosstalk between coagulation and inflammation expands with capsules on protein S signaling, complement, and fibrinolytic inhibitors. Novel agents for hemophilia and thrombosis prevention are introduced. Challenging clinical conditions are also covered, such as inherited platelet disorders and antiphospholipid antibody syndrome. The scientific program in Bangkok will also showcase the work of clinicians and scientists from all parts of the world and chronicle real-world challenges. For example, 2 SOA capsules address the diagnosis and management of von Willebrand disease in low-income settings. Take some time to browse through these short illustrated reviews; we're sure that you'll be entertained, educated, and inspired to further explore the world of thrombosis and hemostasis.

Abstract
OBJECTIVES In addition to gastrointestinal symptoms, pediatric inflammatory bowel disease (pIBD) may present with extra-intestinal manifestations including venous thromboembolism (VTE). Prevention and treatment guidelines for VTE in pediatric patients are needed. In this scoping review, we sought to detail the available data on the prevention and management of VTE in pIBD. METHODS Using PRISMA extension for Scoping Reviews (PRISMA-ScR), we identified, screened, graded quality of, and analyzed, literature on VTE in pediatric IBD, published between 1967 and 2023. RESULTS Data were extracted from 107 studies (including 216 patients). IBD patients with VTE had a median age of 14 years. Children with VTE more frequently had ulcerative colitis (70%, n = 216), developed their VTE within the first year of IBD diagnosis (52%, n = 97), had recent steroid use (62%, n = 50), and had central venous catheters (38%, n = 42). Cerebral venous sinus thrombus was the most common VTE type (34% of all VTE). Testing for thrombophilia conditions was rarely available but 65% (n = 23) of subjects tested had elevated Factor VIII activity. While most patients made a full recovery, 5% (n = 11) died secondary to their VTE. CONCLUSIONS While randomized clinical trials assessing interventions to prevent and treat VTE in pIBD would be ideal, the feasibility of doing such studies is low. However, there has been an increase in interest in this topic and an increase in literature over the past decade. As such, a consensus statement from a multidisciplinary group of experts based on available literature and clinical experience would be valuable for practicing clinicians.

Abstract
Inflammatory bowel disease (IBD) refers to chronic conditions with a low mortality but high disability. The multisystemic nature of these diseases can explain the appearance of some extraintestinal manifestations, including liver damage. Abnormal liver biochemical tests can be identified in approximately one third of patients with IBD and chronic liver disease in 5% of them. Among the liver diseases associated with IBD are primary sclerosing cholangitis, cholelithiasis, fatty liver disease, hepatic amyloidosis, granulomatous hepatitis, drug-induced liver injury, venous thromboembolism, primary biliary cholangitis, IgG4-related cholangiopathy, autoimmune hepatitis, liver abscesses or the reactivation of viral hepatitis. The most common disease is primary sclerosing cholangitis, a condition diagnosed especially in patients with ulcerative colitis. The progress registered in recent years in the therapeutic management of IBD has not eliminated the risk of drug-induced liver disease. Additionally, the immunosuppression encountered in these patients increases the risk of opportunistic infections, including the reactivation of viral hepatitis. Currently, one of the concerns consists of establishing an efficiency and safety profile of the use of direct-acting antiviral agents (DAA) among patients with hepatitis C and IBD. Early diagnosis and optimal treatment of liver complications can improve the prognoses of these patients.

Abstract
Anastomotic leaks remain a dreaded complication after ileal pouch anal anastomosis (IPAA). Their impacts can be devastating, ranging from an acute leak leading to postoperative sepsis to chronic leaks and sinus tracts resulting in long-term pouch dysfunction and subsequent pouch failure. The management of acute leaks is intricate. Initial management is important to resolve acute sepsis, but the type of acute intervention impacts long-term pouch function. Aggressive management in the postoperative period, including the use of IV fluids, broad-spectrum antibiotics, and operative interventions may be necessary to preserve pouch structure and function. Early identification and knowledge of the most common areas of leak, such as at the IPAA anastomosis, are important for guiding management. Long-term complications, such as pouch sinuses, pouch-vaginal fistulas, and diminished IPAA function complicate the overall survival and functionality of the pouch. Knowledge and awareness of the identification and management of leaks is crucial for optimizing IPAA success.

Null Function of Npr1 Disturbs Immune Response in Colonic Inflammation During Early Postnatal Stage. Inflammation 2022; 45:2419-2432.

Abstract
Natriuretic peptide receptor 1 (NPR1) is conventionally known as a regulator of vascular homeostasis. Here, we generated an Npr1 knockout mouse model with CRISPR/Cas9 technology and found that homozygous mice (Npr1−/−) exhibited weight loss and poor survival rate during early postnatal stage. Careful examination revealed unexpectedly that Npr1−/− mice developed colitis characterized by shortened colon, evident colonic mucosal damage, increased histopathological score, and higher colonic expression of proinflammatory cytokines interleukin-1B (IL1B) and -6 (IL6). RNA-sequencing analysis revealed that differentially expressed genes were prominently enriched in the biological pathways related to immune response in both spleen and colon of Npr1−/− mice. Cytofluorimetric analysis demonstrated that leukocytes in the spleen were significantly increased, particularly, the populations of neutrophil and CD3+ T cell were elevated but CD4+ T cells were decreased in Npr1−/− mice. Administration of 8-Br-cGMP, a downstream activator of NPR1, restored these immune-cell populations disturbed in Npr1−/− mice and lessened the colitis-related phenotypes. To validate the involvement of Npr1 in colitis, we examined another mouse model induced by dextran sodium sulfate (DSS) and found a decreased Npr1 expression and shifted immune-cell populations as well. Importantly, 8-Br-cGMP treatment exhibited a similar effect in the restoration of immune-cell populations and attenuation of colonic inflammation in DSS mice. Our data indicate that loss of Npr1 possibly interrupts immune response, which is critical to the pathogenesis of colitis in the early life.

Abstract
Pulmonary manifestation (PM) of inflammatory bowel disease (IBD) in children is a rare condition. The exact pathogenesis is still unclear, but several explanatory concepts were postulated and several case reports in children were published. We performed a systematic Medline search between April 1976 and April 2022. Different pathophysiological concepts were identified, including the shared embryological origin, “miss-homing” of intestinal based neutrophils and T lymphocytes, inflammatory triggering via certain molecules (tripeptide proline-glycine-proline, interleukin 25), genetic factors and alterations in the microbiome. Most pediatric IBD patients with PM are asymptomatic, but can show alterations in pulmonary function tests and breathing tests. In children, the pulmonary parenchyma is more affected than the airways, leading histologically mainly to organizing pneumonia. Medication-associated lung injury has to be considered in pulmonary symptomatic pediatric IBD patients treated with certain agents (i.e., mesalamine, sulfasalazine or infliximab). Furthermore, the risk of pulmonary embolism is generally increased in pediatric IBD patients. The initial treatment of PM is based on corticosteroids, either inhaled for the larger airways or systemic for smaller airways and parenchymal disease. In summary, this review article summarizes the current knowledge about PM in pediatric IBD patients, focusing on pathophysiological and clinical aspects.

Abstract
In children with gastrointestinal disorders such as inflammatory bowel disease (IBD) and intestinal failure (IF), the risk of venous thromboembolism (VTE) is increased. VTE may lead to pulmonary embolism, sepsis and central line infection, stroke and post-thrombotic syndrome. The purpose of this review is to summarize current knowledge and recent advances around VTE management in pediatric gastroenterology with a focus on IBD and IF. The VTE incidence in children with IBD is reported to be around 4-30 per 10,000 patient-years, with higher incidences for hospitalized children. While in general, IF is less common than IBD, the VTE incidence in children with IF is around 750 per 10,000 patient-years. The most common risk factors for development of VTE involve deviations leading to Virchow's triad (endothelial damage, stasis, and hypercoagulability) and include active inflammation, particularly with colonic involvement, presence of a central venous catheter, underlying thrombophilia, reduced mobility, surgery, and hospitalization. Classes of anticoagulants used for treatment of VTE are low molecular weight heparins and vitamin K antagonists. However, the use of direct oral anticoagulants for treatment or prevention of VTE has not been studied in this pediatric population yet. Pediatric gastroenterologists apply different VTE prevention and treatment strategies due to lack of literature and lack of consensus. We discuss the role of primary and secondary prophylactic use of anticoagulants, and provide tools and recommendations for screening, prevention and management for the specific pediatric populations.

Abstract
Iron deficiency anemia has a high prevalence in children and has repeatedly been implicated as a risk factor for arterial and venous thrombosis. As an effective therapy for iron deficiency anemia is available, understanding the association between this form of anemia and the potentially severe thrombosis phenotype is of major clinical interest. Recent findings shed light on pathophysiology of hypercoagulability resulting from iron-restricted erythropoiesis. Specifically, an animal model of induced iron deficiency allowed identifying multiple mechanisms, by which iron deficiency anemia results in increased thrombus formation and thrombus progression both in arterial and venous thrombosis. These findings complement and support conclusions derived from clinical data. The purpose of this mini review is to summarize current evidence on the association of iron deficiency anemia and thrombosis. We want to increase the awareness of iron deficiency as a risk factor for thrombosis in the pediatric population. We discuss how novel pathophysiological concepts can be translated into the clinical settings and suggest clinical studies on prevention and treatment strategies in high-risk patient groups.
