Abstract
BACKGROUND Many affected by pancreatitis harbor rare variants of the cystic fibrosis (CF) gene, CFTR, which encodes an epithelial chloride/bicarbonate channel. We investigated CFTR function and the effect of CFTR modulator drugs in pancreatitis patients carrying CFTR variants. METHODS Next-generation sequencing was performed to identify CFTR variants. Sweat tests and nasal potential difference (NPD) assays were performed to assess CFTR function in vivo. Intestinal current measurement (ICM) was performed on rectal biopsies. Patient-derived intestinal epithelial monolayers were used to evaluate chloride and bicarbonate transport and the effects of a CFTR modulator combination: elexacaftor, tezacaftor and ivacaftor (ETI). RESULTS Of 32 pancreatitis patients carrying CFTR variants, three had CF-causing mutations on both alleles and yielded CF-typical sweat test, NPD and ICM results. Fourteen subjects showed a more modest elevation in sweat chloride levels, including three that were provisionally diagnosed with CF. ICM indicated impaired CFTR function in nine out of 17 non-CF subjects tested. This group of nine included five carrying a wild type CFTR allele. In epithelial monolayers, a reduction in CFTR-dependent chloride transport was found in six out of 14 subjects tested, whereas bicarbonate secretion was reduced in only one individual. In epithelial monolayers of four of these six subjects, ETI improved CFTR function. CONCLUSIONS CFTR function is impaired in a subset of pancreatitis patients carrying CFTR variants. Mutations outside the CFTR locus may contribute to the anion transport defect. Bioassays on patient-derived intestinal tissue and organoids can be used to detect such defects and to assess the effect of CFTR modulators.

Abstract
This is the third paper in the series providing updated information and recommendations for people with cystic fibrosis transmembrane conductance regulator (CFTR)-related disorder (CFTR-RD). This paper covers the individual disorders, including the established conditions - congenital absence of the vas deferens (CAVD), diffuse bronchiectasis and chronic or acute recurrent pancreatitis - and also other conditions which might be considered a CFTR-RD, including allergic bronchopulmonary aspergillosis, chronic rhinosinusitis, primary sclerosing cholangitis and aquagenic wrinkling. The CFTR functional and genetic evidence in support of the condition being a CFTR-RD are discussed and guidance for reaching the diagnosis, including alternative conditions to consider and management recommendations, is provided. Gaps in our knowledge, particularly of the emerging conditions, and future areas of research, including the role of CFTR modulators, are highlighted.

Abstract
Patients with Cystic Fibrosis (CF) are at increased risk of acute (AP) and chronic (CP) pancreatitis, and their complications. The extent of remaining healthy pancreatic parenchyma determines the risk of developing future episodes of pancreatitis, as well as pancreatic exocrine or endocrine insufficiency. Pancreatitis may be the presenting symptom of CF, and genetic testing is especially important in pediatrics. AP and recurrent AP are managed with intravenous fluid hydration and pain control, in addition to early refeeding and treatment of complications. With the use of modulator therapy in CF, pancreatic function may be restored to some extent. CP related pain is managed with analgesics and neuromodulators, with surgery if indicated in specific situations including TPIAT as a possible type of surgical intervention. Long-term sequelae of CP in patients with CF include exocrine pancreatic insufficiency treated with pancreatic enzyme replacement therapy, fat-soluble vitamin deficiencies and associated metabolic complications such as bone disease/osteoporosis, pancreatogenic diabetes, and less commonly, pancreatic cancer. We review the presentation and etiologies of pancreatitis in CF patients as well as the management of AP and CP primarily in children.

Abstract
BACKGROUND/OBJECTIVES The event-rate of recurrent acute pancreatitis (RAP) in patient populations is critical for powering research studies. We hypothesize that some patients manage RAP attacks at home, reducing event rate estimations based on counting emergency department (ED) visits and hospitalizations only. The aim of this study was to determine the rates of home self-management of recurrent acute pancreatitis compared to ED visits and hospitalizations. METHODS An anonymous 8-question survey was sent to 1825 individuals on an email list of individuals with a history of acute pancreatitis (AP) or chronic pancreatitis or interest in pancreatic diseases. Question were designed to identify subjects with RAP within the past 2 years and to subdivide patients based on having a chronic pain syndrome or not. RESULTS After an initial email request and one reminder a total of 194 subjects responded with 98 RAP subjects suitable for analysis. Annual AP events included an average of 1.44 hospitalizations, 1.37 ED visits, 2.46 disrupted work/school/social engagements, and 3.95 pancreatitis-like pain attacks per year. Patients with RAP average 6.8 RAP events per year with 58.4 % managed at home. CONCLUSIONS The burden of disease in patients with RAP is significantly underestimated, especially for patients with chronic pain. Future studies should include measures to capture RAP events managed at home and utilize methods of documenting RAP events.

Abstract
The incidence of pancreatitis in children has increased over the past two decades. With advances in molecular biological techniques and clinical research, genetic variations have emerged as a pivotal etiological factor in pediatric pancreatitis. This review aims to summarize recent clinical research advancements in understanding pediatric pancreatitis caused by various gene mutations. As of the year 2020, researchers had identified 12 genes implicated in the pathogenesis of pancreatitis. These genes primarily contributed to the development of pancreatitis through three mechanisms. Pancreatitis resulting from these gene mutations exhibits several distinct characteristics, including early onset, a heightened risk of developing pancreatic duct stones, rapid disease progression, and a significantly increased risk of pancreatic endocrine and exocrine dysfunction, as well as pancreatic cancer in the future. Genetic sequencing is recommended for children with pancreatitis based on six indications. The sequencing not only assists in the clinical diagnosis but also enhances our understanding of the pathophysiology of pancreatitis.

Abstract
Cystic fibrosis (CF) is a genetic disease caused by mutations in the gene encoding for the ion channel cystic fibrosis transmembrane conductance regulator (CFTR). The management of CF disease has evolved in recent decades from treating downstream disease manifestations affecting the airways, the lungs and the gastrointestinal system to addressing the CFTR gene defect. The advent of CFTR modulators, which correct the functionality of the defective CFTR, contributes to reshaping the landscape of CF demographics, prognosis and therapies, including nutritional management. A spectrum of clinical manifestations is emerging within the same patient population where undernutrition and nutritional deficiencies coexist with excessive weight gain and metabolic derangements. Such contrasting presentations challenge current practices, require adjustments to traditional approaches, and involve more individualised interventions. This narrative review examines the current state of knowledge on the nutritional management of people living with cystic fibrosis from early life to adulthood in the era of CFTR modulation.

Abstract
Cystic fibrosis transmembrane conductance regulator modulator therapy is associated with substantial clinical benefit and improved quality of life in patients with cystic fibrosis (CF). While their effect on lung function has been clearly reported, we are still in the process of unraveling the full impact they have on the pancreas. We present two cases of pancreatic-insufficient CF patients who presented with acute pancreatitis shortly after commencing elexacaftor/tezacaftor/ivacaftor modulator therapy. Both patients were treated with ivacaftor for 5 years prior to elexacaftor/tezacaftor/ivacaftor initiation, but had no previous episodes of acute pancreatitis. We suggest that highly effective modulator combination therapy may restore additional pancreatic acinar activity, resulting in the development of acute pancreatitis in the interim until ductal flow is improved. This report adds to the growing evidence for possible restoration of pancreatic function in patients receiving modulator therapy, and highlights that treatment with elexacaftor/tezacaftor/ivacaftor may be associated with acute pancreatitis until ductal flow is restored, even in pancreatic-insufficient CF patients.

Abstract
The course of cystic fibrosis (CF) as a nutritional illness is diverging since the introduction of highly effective modulator therapy, leading to more heterogeneous phenotypes of the disease despite CF genetic mutations that portend worse prognosis. This may become more evident as we follow the pediatric CF population into adulthood as some highly effective modulator therapies (HEMT) are approved for those as young as 1 year old. This review will outline the current research and knowledge available in the evolving nutritional health of people with CF as it relates to the impact of HEMT on anthropometrics, body composition, and energy expenditure, exocrine and endocrine pancreatic insufficiencies (the latter resulting in CF-related diabetes), vitamin and mineral deficiencies, and nutritional health in CF as it relates to pregnancy and lung transplantation.

Abstract
Pediatric patients with exocrine pancreatic insufficiency (EPI) have symptoms that include abdominal pain, weight loss or poor weight gain, malnutrition, and steatorrhea. This condition can be present at birth or develop during childhood for certain genetic disorders. Cystic fibrosis (CF) is the most prevalent disorder in which patients are screened for EPI; other disorders also are associated with pancreatic dysfunction, such as hereditary pancreatitis, Pearson syndrome, and Shwachman-Diamond syndrome. Understanding the clinical presentation and proposed pathophysiology of the pancreatic dysfunction of these disorders aids in diagnosis and treatment. Testing pancreatic function is challenging. Directly testing aspirates produced from the pancreas after stimulation is considered the gold standard, but the procedures are not standardized or widely available. Instead, indirect tests are often used in diagnosis and monitoring. Although indirect tests are more widely available and easier to perform, they have inherent limitations due to a lack of sensitivity and/or specificity for EPI.

Abstract
INTRODUCTION The mechanistic definition of chronic pancreatitis (CP) identifies acute pancreatitis (AP) as a precursor stage. We hypothesized that clinical AP frequently precedes the diagnosis of CP and is associated with patient- and disease-related factors. We describe the prevalence, temporal relationship and associations of AP in a well-defined North American cohort. METHODS We evaluated data from 883 patients with CP prospectively enrolled in the North American Pancreatitis Studies across 27 US centers between 2000 and 2014. We determined how often patients had one or more episodes of AP and its occurrence in relationship to the diagnosis of CP. We used multivariable logistic regression to determine associations for prior AP. RESULTS There were 624/883 (70.7%) patients with prior AP, among whom 161 (25.8%) had AP within 2 years, 115 (18.4%) within 3-5 years, and 348 (55.8%) >5 years prior to CP diagnosis. Among 504 AP patients with available information, 436 (86.5%) had >1 episode. On multivariable analyses, factors associated with increased odds of having prior AP were a younger age at CP diagnosis, white race, abdominal pain, pseudocyst(s) and pancreatic duct dilatation/stricture, while factors associated with a lower odds of having prior AP were exocrine insufficiency and pancreatic atrophy. When compared with patients with 1 episode, those with >1 AP episode were diagnosed with CP an average of 5 years earlier. CONCLUSIONS Nearly three-quarters of patients were diagnosed with AP prior to CP diagnosis. Identifying which AP patients are at-risk for future progression to CP may provide opportunities for primary and secondary prevention.

Abstract
Cystic fibrosis (CF) is a complex multiorgan disease, which often affects the gastrointestinal tract. With improved CF specific therapies and multidisciplinary management, patients with CF are now living longer with a median life expectancy of around 50 years. This increased life expectancy has resulted in corresponding increase in presentations of the CF patient with comorbid surgical conditions that were never important considerations. Investigations and management of these conditions, such as distal intestinal obstruction syndrome and colorectal cancer warrant good clinical understanding of the unique challenges that CF patients present including chronic immunosuppression, impaired respiratory function and their multi-organ dysfunction. The purpose of this review is to provide general surgeons with a contemporary update on the CF related surgical issues as they are likely to become increasingly involved in the care of these complex patients and form an integral part of the multidisciplinary team.

Abstract
Acute pancreatitis is a common indication for hospital admission, increasing in incidence, including in children, pregnancy and the elderly. Moderately severe acute pancreatitis with fluid and/or necrotic collections causes substantial morbidity, and severe disease with persistent organ failure causes significant mortality. The diagnosis requires two of upper abdominal pain, amylase/lipase ≥ 3 ×upper limit of normal, and/or cross-sectional imaging findings. Gallstones and ethanol predominate while hypertriglyceridaemia and drugs are notable among many causes. Serum triglycerides, full blood count, renal and liver function tests, glucose, calcium, transabdominal ultrasound, and chest imaging are indicated, with abdominal cross-sectional imaging if there is diagnostic uncertainty. Subsequent imaging is undertaken to detect complications, for example, if C-reactive protein exceeds 150 mg/L, or rarer aetiologies. Pancreatic intracellular calcium overload, mitochondrial impairment, and inflammatory responses are critical in pathogenesis, targeted in current treatment trials, which are crucially important as there is no internationally licenced drug to treat acute pancreatitis and prevent complications. Initial priorities are intravenous fluid resuscitation, analgesia, and enteral nutrition, and when necessary, critical care and organ support, parenteral nutrition, antibiotics, pancreatic exocrine and endocrine replacement therapy; all may have adverse effects. Patients with local complications should be referred to specialist tertiary centres to guide further management, which may include drainage and/or necrosectomy. The impact of acute pancreatitis can be devastating, so prevention or reduction of the risk of recurrence and progression to chronic pancreatitis with an increased risk of pancreas cancer requires proactive management that should be long term for some patients.

Cystic fibrosis transmembrane conductance regulator modulators and the exocrine pancreas: A scoping review. J Cyst Fibros 2022; 22:193-200. [PMID: 36008229 DOI: 10.1016/j.jcf.2022.08.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 07/21/2022] [Accepted: 08/10/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Cystic fibrosis transmembrane conductance regulator (CFTR) modulators improve pulmonary outcomes in subjects with cystic fibrosis (CF); however, the effects on pancreatic manifestations are not well characterized. We hypothesized that CFTR modulators would improve measures of exocrine pancreatic function and outcomes. METHODS We performed a systematic search to identify studies reporting measures of the exocrine pancreas in humans treated with CFTR modulators. Only studies reporting baseline and on-treatment assessments were included. RESULTS Of 630 identified studies, 41 met inclusion criteria. CFTR modulators reduced acute pancreatitis events by 85% overall (rate ratio 0.15, 95% confidence interval (CI) 0.04, 0.52), with a greater effect seen in the subgroup with pancreas sufficient CF (PS-CF) (rate ratio 0.13 (95% CI 0.03, 0.53). Among 293 subjects with baseline and on-treatment evaluation of pancreas sufficiency, 253 were pancreas insufficient at baseline and 54 (21.3%) converted to pancreas sufficiency. Of 32 subjects with baseline FE-1 values <200 mcg/g, 16 (50%) increased to ≥200 mcg/g. Serum trypsin decreased by a mean of 565.9 ng/mL (standard deviation (SD) 311.8), amylase decreased by 38.2 U/L (SD 57.6), and lipase decreased by 232.3 U/L (SD 247.7). CONCLUSIONS CFTR modulator use reduces acute pancreatitis frequency and improves indirect measures of exocrine pancreas function. Future interventional studies that evaluate the mechanism and impact of CFTR modulators on acute pancreatitis and pancreas sufficiency in patients with CFTR dysfunction are warranted.

Abstract
Over the past decade there have been significant developments in the field of Cystic Fibrosis Transmembrane Regulator modulator drugs. Following treatment in patients with cystic fibrosis with common gating mutations using the potentiator drug ivacaftor, successive development of corrector drugs used in combination has led to highly effective modulator therapy being available to more than 85% of the cystic fibrosis population over 12 years of age in the form of elexacaftor/tezacaftor/ivacaftor. In this article, we review the evidence from clinical trials and mounting real-world observational and registry data that demonstrates the impact highly effective modulators have on both pulmonary and extra-pulmonary manifestations of cystic fibrosis. As clinical trials progress to younger patient groups, we discuss the challenges to demonstrating drug efficacy in early life, and also consider practicalities of drug development in an ever-shrinking modulator-naïve population. Drug-drug interactions are an important consideration in people with cystic fibrosis, where polypharmacy is commonplace, but also as the modulated population look to remain healthier for longer, we identify trials that aim to address treatment burden too. Inequity of care, through drug cost or ineligibility for modulators by genotype, is widening without apparent strategies to address this; however, we present evidence of hopeful early-stage drug development for non-modulatable genes and summarise the current state of gene-therapy development.

Abstract
Cystic fibrosis (CF) - although primarily a lung disease - also causes a variety of gastrointestinal manifestations which are important for diagnosis, prognosis and quality of life. All parts of the gastrointestinal tract can be affected by CF. Besides the well-known pancreatic insufficiency, gastroesophageal reflux disease, liver disease and diseases of the large intestine are important pathologies that impact on prognosis and also impair quality of life. Diagnosis and management of gastrointestinal manifestations will be discussed in this review. Since optimisation of CF therapy is associated with a significantly longer life-span of CF patients nowadays, also gastrointestinal malignancies, which are more common in CF than in the non-CF population need to be considered. Furthermore, novel evidence on the role of the gut microbiome in CF is emerging. The introduction of cystic fibrosis transmembrane conductance regulator (CFTR) protein modulators gives hope for symptom alleviation and even cure of gastrointestinal manifestations of CF.

Abstract
INTRODUCTION Cystic fibrosis transmembrane conductance regulator (CFTR)-mediated chloride and bicarbonate secretion is integral to the pancreas' ability to produce the alkaline pancreatic juice required for proper activation of enzymes for digestion. Disruption in this process increases the risk for pancreatitis. AREAS COVERED Using original basic and clinical research, as well as clinical case reports and recent reviews indexed in PubMed, we discuss why patients with CFTR dysfunction are at risk for pancreatitis. We also discuss diagnostic modalities for assessing CFTR function, as well as new therapeutic advancements and the impact these are having on pancreatic function, pancreatitis in particular. EXPERT OPINION CFTR-related pancreatitis occurs in the presence of monallelic or biallelic mutations and/or from toxin-mediated channel disruption. Research-based CFTR diagnostics have been expanded, yet all current methods rely on measuring CFTR chloride transport in non-pancreatic cells/tissue. Newer CFTR-directed therapies ('CFTR modulators') are both improving pancreatitis (pancreatic-sufficient CF patients) and increasing the risk for pancreatitis (previously pancreatic-insufficient CF patients). Our experiences with these drugs are enlightening us on how CFTR modulation can affect pancreatitis risk across a wide spectrum of pancreatic disease, and represents an opportunity for therapeutic relief from pancreatitis in those without CF, but who suffer from CFTR-related pancreatitis.

Abstract
ABSTRACT Recent research breakthroughs have emerged from applied basic research throughout all scientific areas, including adult and paediatric gastroenterology, hepatology and nutrition (PGHAN). The research landscape within the European Society of Paediatric Gastroenterology and Nutrition (ESPGHAN) is also inevitably changing from clinical research to studies involving applied laboratory research. This position paper aims to depict the current status quo of basic science and translational research within ESPGHAN, and to delineate how the society could invest in research in the present and future time. The paper also explores which research areas in the field of PGHAN represent the current and future priorities, and what type of support is needed across the ESPGHAN working groups (WGs) and special interest groups (SIGs) to fulfil their research goals.

Abstract
OBJECTIVE The aim of the present study is to assess the impact of smoking dose and duration on the distribution of risk factor(s) in patients with RAP and CP, and the impact of genetic testing on the distribution of risk factor(s) in patients with idiopathic RAP and CP. METHODS All adult patients with RAP and CP referred to a multidisciplinary pancreatitis clinic between 2010 and 2017 were evaluated. Risk factors included alcohol and smoking, hypertriglyceridemia, biliary, and other etiologies. Genetic testing was only pursued in patients with idiopathic RAP or CP. RESULTS Among the 1770 patients evaluated, 167 had RAP and 303 had CP. After genetic testing and smoking, the most common risk factors for RAP and CP were pathogenic variant(s) (23%) and the combination of alcohol and smoking (23%), respectively. Genetic testing and smoking assessment decreased the proportion of patients with alcoholic RAP from 17% to 5%, alcoholic CP from 33% to 10%, idiopathic RAP from 49% to 12%, and idiopathic CP from 54% to 14%. Pathogenic CFTR variants were the most common variant in patients with RAP (51%) and CP (43%). Among the 68 patients with pancreas divisum, other risk factor(s) were identified in 72%. CONCLUSION Genetic testing and a detailed assessment of smoking dose and duration reduce the proportion of patients with alcoholic and idiopathic pancreatitis. Other risk factor(s) for pancreatitis are found in the majority of patients with pancreas divisum further questioning its role as an independent risk factor.1. What is the current knowledge?Approximately 30% of patients with pancreatitis have no clear risk factor(s) and are categorized as having an idiopathic etiology.Pathogenic variant(s) as well as smoking dose and duration are well-established risk factors for recurrent acute and chronic pancreatitis but are not widely recognized or incorporated into clinical practice.2. What is new here?Genetic testing and a detailed assessment of smoking dose and duration reduced the proportion of patients with alcoholic and idiopathic acute recurrent and chronic pancreatitis.Approximately three-fourths of patients with pancreas divisum have a risk factor for pancreatitis.

Abstract
Traditional approaches to understanding the origins of chronic pancreatitis (CP) and find treatments led to abysmal failure. Thus, no drugs now exists to meet this need. Outdated concepts of the etiopathogenesis of CP have been replaced with new insights and disease models that provide the framework for early detection of the pathogenic pancreatitis process. Application of these principals require a new paradigm in disease definition and management, i.e. personalized / precision medicine. The key is acute pancreatitis (AP) starting with the first (sentinel) acute pancreatitis (AP) event (SAPE). This event sensitizes the pancreas to recurrent acute pancreatitis (RAP) as ongoing stressors drive various inflammatory responses to cause CP. The problem is the complex etiologies of AP and the additional genetic and environmental factors that promote progression to RAP and CP. This paper provides a background on the key conceptual changes that facilitate new approaches and the rationale for using mechanism-specific therapies to prevent RAP and CP.

Abstract
CFTR, the cystic fibrosis (CF) gene-encoded epithelial anion channel, has a prominent role in driving chloride, bicarbonate and fluid secretion in the ductal cells of the exocrine pancreas. Whereas severe mutations in CFTR cause fibrosis of the pancreas in utero, CFTR mutants with residual function, or CFTR variants with a normal chloride but defective bicarbonate permeability (CFTRBD), are associated with an enhanced risk of pancreatitis. Recent studies indicate that CFTR function is not only compromised in genetic but also in selected patients with an acquired form of pancreatitis induced by alcohol, bile salts or smoking. In this review, we summarize recent insights into the mechanism and regulation of CFTR-mediated and modulated bicarbonate secretion in the pancreatic duct, including the role of the osmotic stress/chloride sensor WNK1 and the scaffolding protein IRBIT, and current knowledge about the role of CFTR in genetic and acquired forms of pancreatitis. Furthermore, we discuss the perspectives for CFTR modulator therapy in the treatment of exocrine pancreatic insufficiency and pancreatitis and introduce pancreatic organoids as a promising model system to study CFTR function in the human pancreas, its role in the pathology of pancreatitis and its sensitivity to CFTR modulators on a personalized basis.

Cystic Fibrosis Transmembrane Conductance Regulator Modulator Use Is Associated With Reduced Pancreatitis Hospitalizations in Patients With Cystic Fibrosis. Am J Gastroenterol 2021; 116:2446-2454. [PMID: 34665155 PMCID: PMC8900539 DOI: 10.14309/ajg.0000000000001527] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 09/09/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Acute pancreatitis (AP) occurs among patients with pancreas-sufficient cystic fibrosis (PS-CF) but is reportedly less common among patients with pancreas-insufficient cystic fibrosis (PI-CF). The incidence of AP may be influenced by cystic fibrosis transmembrane conductance regulator (CFTR) modulator use. We hypothesized that CFTR modulators would reduce AP hospitalizations, with the greatest benefit in PS-CF. METHODS MarketScan (2012-2018) was queried for AP hospitalizations and CFTR modulator use among patients with CF. Multivariable Poisson models that enabled crossover between CFTR modulator treatment groups were used to analyze the rate of AP hospitalizations on and off therapy. Pancreas insufficiency was defined by the use of pancreas enzyme replacement therapy. RESULTS A total of 10,417 patients with CF were identified, including 1,795 who received a CFTR modulator. AP was more common in PS-CF than PI-CF (2.9% vs 0.9%, P = 0.007). Overall, the observed rate ratio of AP during CFTR modulator use was 0.33 (95% confidence interval [CI] 0.10, 1.11, P = 0.07) for PS-CF and 0.38 (95% CI 0.16, 0.89, P = 0.03) for PI-CF, indicating a 67% and 62% relative reduction in AP hospitalizations, respectively. In a subset analysis of 1,795 patients who all had some CFTR modulator use, the rate ratio of AP during CFTR modulator use was 0.36 (95% CI 0.13, 1.01, P = 0.05) for PS-CF and 0.53 (95% CI 0.18, 1.58, P = 0.26) for PI-CF. DISCUSSION CFTR modulator use is associated with a reduction in AP hospitalizations among patients with CF. These observational data support the prospective study of CFTR modulators to reduce AP hospitalizations among patients with CF.

Abstract
PURPOSE OF REVIEW Approximately 20-30% of children who experience one episode of acute pancreatitis will have at least one additional episode. For some children, pancreatitis recurs multiple times and in a few years is followed by the diagnosis of chronic pancreatitis. Identifying risk factors for recurrent episodes and disease progression is critical to developing therapeutic interventions. RECENT FINDINGS Obesity is driving an increase in biliary stone disease and severe acute pancreatitis. Recurrent acute pancreatitis (RAP) may lead to the development of diabetes through autoimmune mechanisms. Cystic fibrosis or CFTR-related disorders may present as RAP and CFTR modulator therapy can increase or decrease the risk of acute pancreatitis in these populations. Children with Crohn disease have a three-fold risk of acute pancreatitis over the general population while children with ulcerative colitis are at increased risk for pediatric autoimmune pancreatitis, a disorder that may be distinct from autoimmune pancreatitis described in adults. Obstructive jaundice in the absence of identified mechanical factors may be a presenting sign of pediatric autoimmune pancreatitis. SUMMARY Pediatric RAP is a painful condition that leads to gland destruction and functional insufficiency. Risk factors are being clarified but preventive treatments remain elusive.

Abstract
Pulmonary manifestations of gastrointestinal (GI) diseases are often subtle, and underlying disease may precede overt symptoms. A high index of suspicion and a low threshold for consultation with a pediatric pulmonologist is warranted in common GI conditions. This article outlines the pulmonary manifestations of different GI, pancreatic, and liver diseases in children, including gastroesophageal reflux disease, inflammatory bowel disease, pancreatitis, alpha1-antitrypsin deficiency, nonalcoholic fatty liver disease, and complications of chronic liver disease (hepatopulmonary syndrome and portopulmonary hypertension).

Abstract
PURPOSE OF REVIEW The pancreas is highly affected in cystic fibrosis, with complications occurring early in childhood. This review highlights recent research in exocrine pancreatic function in the era of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies and discusses how these are affecting pancreatitis and exocrine pancreatic insufficiency (EPI) in children. Additionally, new research into exocrine--endocrine interactions sheds light on how CFTR dysfunction in ductal cells may affect beta cells. RECENT FINDINGS Ivacaftor has disproved the hypothesis that EPI in children with cystic fibrosis is irreversible. Improvements in pancreatic function have increased pancreatitis episodes in some children and reduced them in others. Imaging advances are providing complementary methods for exocrine pancreatic function testing. New research into the interplay between the exocrine and endocrine components of the pancreas are elucidating the intertwined and complex relationship between the exocrine and endocrine pancreas. SUMMARY Pancreatic complications contribute to the morbidity and mortality of children with cystic fibrosis. Increasing use of highly effective CFTR modulators will not only abrogate these but will also advance our understanding of pancreatic pathophysiology in cystic fibrosis. New frontiers into pancreatic gene therapy and exocrine--endocrine research will help provide new therapeutic opportunities for pancreatitis, EPI, and diabetes in cystic fibrosis.

Abstract
Recurrent acute and chronic pancreatitis are increasingly recognized in childhood. Etiologies are vastly different in children compared with adults and mostly involve genetic and anatomical factors with negligible contribution of environmental risks. Pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) have significant impact on quality of life with high healthcare costs. Children with these conditions suffer from recurrent acute or chronic abdominal pain and they endure multiple emergency room visits, hospitalizations, procedures, and surgeries. Diagnostic methods are being developed; treatment options are limited. This review summarizes the most recent developments in pediatric ARP and CP. These discoveries will help physicians provide optimal care for children with these conditions.
