Abstract
INTRODUCTION IgG4-related disease (IgG4-RD) is an immune-mediated systemic fibroinflammatory condition characterized by serum IgG4 elevation and IgG4-positive plasma cell infiltration into various organs. It generally occurs in elderly males. Pediatric cases have been reported, albeit rarely, accordingly lack of recognition of such cases could delay therapeutic intervention leading to poorer outcomes. AREAS COVERED The present review is a descriptive review of all published case reports, cohort studies, and reviews of pediatric IgG4-RD listed in PubMed. Characteristics of pediatric IgG4-RD were clarified, including sex, organ involvement, serological and histological findings, and treatment. We assessed how many published cases met current classification and comprehensive diagnostic criteria. EXPERT OPINION The characteristics of pediatricIgG4-RD differed from adult IgG4-RD in terms of sex and involved organs. There was no clear male dominance in numbers of cases, and surface organ involvement such as ophthalmic diseases were more common in the pediatric IgG4-RD. Organ involvement tended to be indolent and unilateral, causing difficulty in definitively diagnosing pediatric IgG4-RD. Only about 20% of published cases met IgG4-RD classification or comprehensive diagnostic criteria. Physicians should be careful in diagnosing pediatric IgG4-RD after excluding mimickers. International collaboration toward high-quality evidence to support diagnosis and treatment of pediatric IgG4-RD is advised.

Abstract
Autoimmune pancreatitis (AIP) is rare cause of abdominal pain in children who often present with obstructive jaundice, mimicking malignancy. An investigation of clinical symptoms, serology, imaging, and histopathology is necessary for diagnosis. We report a 10-year-old female presenting with abdominal pain and jaundice, ultimately found to have AIP after confirmation with tissue pathology. Our patient's prompt response to corticosteroid initiation is characteristic of this disease state. AIP has 2 subtypes, the second of which is more frequently found in children. Our patient's pathology did not fit perfectly with either subtype, but had features found in each one. While diagnostic criteria for AIP have not established in pediatrics, our case highlights the combination of clinical symptoms, imaging, and histopathology that children classically present with. While rare, the diagnosis of AIP is associated with comorbidities and must be considered in any child presenting with a pancreatic mass or biliary stricture.

Abstract
Pediatric pancreatitis describes a spectrum covering acute pancreatitis, acute recurrent pancreatitis, and chronic pancreatitis, each with varying clinical manifestations and risk factors requiring a tailored diagnostic approach. We emphasize management strategies based on age, risk factors, recurrence, and complications. A discussion of the role of therapeutic endoscopy is reviewed and highlights the growing role of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography in children with pancreatitis. Particular diagnostic challenges in autoimmune pancreatitis are reviewed with an emphasis on differentiating this entity from alternate pancreaticobiliary pathologies. Finally, we explore a multidisciplinary approach to acute recurrent and chronic pancreatitis.

Abstract
Pediatric acute pancreatitis has distinct etiologic, clinical and prognostic characteristics in contrast to the adult form of the disease. This review offers a comprehensive imaging update that emphasizes the importance of recognizing specific findings that are relevant from the clinical standpoint. Knowledge of these features facilitates communication among multidisciplinary team members and ultimately could lead to the improved care of pediatric acute pancreatitis patients.

Abstract
Inflammatory bowel diseases (IBDs) are chronic relapsing inflammatory conditions of the gastrointestinal tract, encompassing Crohn’s disease (CD), ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBD-U). They are currently considered as systemic disorders determined by a set of genetic predispositions, individual susceptibility and environmental triggers, potentially able to involve other organs and systems than the gastrointestinal tract. A large number of patients experiences one or more extraintestinal manifestations (EIMs), whose sites affected are mostly represented by the joints, skin, bones, liver, eyes, and pancreas. Pancreatic abnormalities are not uncommon and are often underestimated, encompassing acute and chronic pancreatitis, autoimmune pancreatitis, exocrine pancreatic insufficiency and asymptomatic elevation of pancreatic enzymes. In most cases they are the result of environmental triggers. However, several genetic polymorphisms may play a role as precipitating factors or contributing to a more severe course. The aim of this paper is to provide an updated overview on the available evidence concerning the etiology, pathogenesis and clinical presentation of pancreatic diseases in IBD pediatric patients.

Abstract
The loss of tolerance to self-antigens is the unequivocal "red line" of autoimmunity: both development of autoreactive T and B cells and production of polyclonal autoantibodies represent seminal keys to the pathogenesis of protean autoimmune diseases. Most of these autoantibodies are immunoglobulins G (IgG), functionally distinguished in four subclasses named IgG1, IgG2, IgG3, and IgG4, due to structural differences in the hinge and heavy chain constant regions. Different studies analyzed serum levels of IgG subclasses in the course of different disorders, showing that they might have a pathogenic role by regulating interactions among immunoglobulins, Fc-gamma receptors, and complement. To date, the mechanisms promoting different IgG subclasses distribution during the natural history of most autoimmune diseases remain somewhat unclear. Evidence from the medical literature shows that the serum IgG profile is peculiar for many autoimmune diseases, suggesting that different subclasses could be specific for the underlying driving autoantigens. A better knowledge of IgG subsets may probably help to elucidate their pathological task, but also to define their relevance for diagnostic purposes, patients' personalized management, and prognosis assessment.
