Incidence, Admission Rates, and Economic Burden of Adult Emergency Visits for Chronic Pancreatitis: Data From the National Emergency Department Sample, 2006 to 2012.

INTRODUCTION: Chronic pancreatitis (CP) is a common reason for emergency department (ED) visits, but little research has examined ED use by patients with CP. MATERIALS AND METHODS: The Nationwide Emergency Department Sample (2006 to 2012) was interrogated to evaluate trends in adult ED visits for a primary diagnosis of CP (International Classification of Disease, 9th revision, Clinical Modification code: 577.1), the rates of subsequent hospital admission, and total charges. A survey logistic regression model was used to determine factors associated with hospitalization from the ED. RESULTS: We identified 253,753 ED visits with a primary diagnosis of CP. No significant trends in annual incidence were noted. However, the ED-to-hospitalization rates decreased by 3% per year (P<0.001) and mean ED charges after adjusting for inflation increased by 11.8% per year (P<0.001). Higher Charlson comorbidity index, current smoker status, alcohol use, and biliary-related CP were associated with hospitalization. In hospitalized patients, length of stay decreased by 2.2% per year (P=0.003) and inpatient charges increased by 2.9% per year (P=0.004). CONCLUSIONS: Patient characteristics associated with higher risk of hospitalization from the ED deserve further attention.

Risk Factors Associated With Pediatric Acute Recurrent and Chronic Pancreatitis: Lessons From INSPPIRE.

IMPORTANCE: Pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) are poorly understood. OBJECTIVE: To characterize and identify risk factors associated with ARP and CP in childhood. DESIGN, SETTING, AND PARTICIPANTS: A multinational cross-sectional study of children with ARP or CP at the time of enrollment to the INSPPIRE (International Study Group of Pediatric Pancreatitis: In Search for a Cure) study at participant institutions of the INSPPIRE Consortium. From August 22, 2012, to February 8, 2015, 155 children with ARP and 146 with CP (aged ≤19 years) were enrolled. Their demographic and clinical information was entered into the REDCap (Research Electronic Data Capture) database at the 15 centers. Differences were analyzed using 2-sample t test or Wilcoxon rank sum test for continuous variables and Pearson χ2 test or Fisher exact test for categorical variables. Disease burden variables (pain variables, hospital/emergency department visits, missed school days) were compared using Wilcoxon rank sum test. MAIN OUTCOMES AND MEASURES: Demographic characteristics, risk factors, abdominal pain, and disease burden. RESULTS: A total of 301 children were enrolled (mean [SD] age, 11.9 [4.5] years; 172 [57%] female); 155 had ARP and 146 had CP. The majority of children with CP (123 of 146 [84%]) reported prior recurrent episodes of acute pancreatitis. Sex distribution was similar between the groups (57% female in both). Hispanic children were less likely to have CP than ARP (17% vs 28%, respectively; odds ratio [OR] = 0.51; 95% CI, 0.29-0.92; P = .02). At least 1 gene mutation in pancreatitis-related genes was found in 48% of patients with ARP vs 73% of patients with CP (P < .001). Children with PRSS1 or SPINK1 mutations were more likely to present with CP compared with ARP (PRSS1: OR = 4.20; 95% CI, 2.14-8.22; P < .001; and SPINK1: OR = 2.30; 95% CI, 1.03-5.13; P = .04). Obstructive risk factors did not differ between children with ARP or CP (33% in both the ARP and CP groups), but toxic/metabolic risk factors were more common in children with ARP (21% overall; 26% in the ARP group and 15% in the CP group; OR = 0.55; 95% CI, 0.31-0.99; P = .046). Pancreatitis-related abdominal pain was a major symptom in 81% of children with ARP or CP within the last year. The disease burden was greater in the CP group compared with the ARP group (more emergency department visits, hospitalizations, and medical, endoscopic, and surgical interventions). CONCLUSIONS AND RELEVANCE: Genetic mutations are common in both ARP and CP. Ethnicity and mutations in PRSS1 or SPINK1 may influence the development of CP. The high disease burden in pediatric CP underscores the importance of identifying predisposing factors for progression of ARP to CP in children.

Autologous islet transplantation with remote islet isolation after pancreas resection for chronic pancreatitis.

IMPORTANCE: Autologous islet transplantation is an elegant and effective method for preserving euglycemia in patients undergoing near-total or total pancreatectomy for severe chronic pancreatitis. However, few centers worldwide perform this complex procedure, which requires interdisciplinary coordination and access to a sophisticated Food and Drug Administration-licensed islet-isolating facility. OBJECTIVE: To investigate outcomes from a single institutional case series of near-total or total pancreatectomy and autologous islet transplantation using remote islet isolation. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study between March 1, 2007, and December 31, 2013, at tertiary academic referral centers among 9 patients (age range, 13-47 years) with chronic pancreatitis and reduced quality of life after failed medical management. INTERVENTIONS: Pancreas resection, followed by transport to a remote facility for islet isolation using a modified Ricordi technique, with immediate transplantation via portal vein infusion. MAIN OUTCOMES AND MEASURES: Islet yield, pain assessment, insulin requirement, costs, and transport time. RESULTS: Eight of nine patients had successful islet isolation after near-total or total pancreatectomy. Four of six patients with total pancreatectomy had islet yields exceeding 5000 islet equivalents per kilogram of body weight. At 2 months after surgery, all 9 patients had significantly reduced pain or were pain free. Of these patients, 2 did not require insulin, and 1 required low doses. The mean transport cost was $16,527, and the mean transport time was 3½ hours. CONCLUSIONS AND RELEVANCE: Pancreatic resection with autologous islet transplantation for severe chronic pancreatitis is a safe and effective final alternative to ameliorate debilitating pain and to help prevent the development of surgical diabetes. Because many centers lack access to an islet-isolating facility, we describe our experience using a regional 2-center collaboration as a successful model to remotely isolate cells, with outcomes similar to those of larger case series.

[Medico-social characteristics of patients with chronic pancreatitis].

AIM OF STUDY: Comparative analysis of the health status of patients with chronic toxic-metabolic pancreatitis (CTMP) and chronic obstructive pancreatitis (COP). The gender and social factors was analysed. THE MATERIALS AND METHODS: 250 patients with chronic pancreatitis examined. On based of the TIGAR-O classification, two groups of patients choosed: the 1-st group included 142 (56.8%) a patient with CTMP, the 2-nd group--108 (43.2%) patients COP. The social characteristics of patients had produced, including assessment of status social (gender, age, educational level, employment, marital status, bad habits). Quality of life was assessed by using the updated questionnaire SF-36. RESULTS: The average age of patients with CP is 53.2 years, male to female ratio is 3:2. At stake is 56.8% of all CTMP patients with CP, the median age is 42.3 years, the male to female ratio is 4:1. The average age of patients with COP is 54.6 years, male to female ratio is 1:4. Do not work, not married, engaged in an anti-social way of life 43% of people working age with CTMP, have a lower education in comparison with patients with COP. CONCLUSION: Patients with CTMP reduced social significance illustrate reduced social significance as personal (reduction in the level of education, an anti-social way of life), and social (lack of employment, deterioration of demographic indicators).

The epidemiology and socioeconomic impact of chronic pancreatitis.

Epidemiological studies have been published worldwide in recent decades describing the incidence, mortality, aetiology and trends of chronic pancreatitis. Accumulated evidence suggests that chronic pancreatitis is increasing in incidence and hospital admission rates are rising accordingly. Alcoholic chronic pancreatitis was previously more common in the developed world than elsewhere, but is now increasing worldwide due to growing per capita alcohol consumption in each nation. Supporting alcohol and smoking cessation in individual patients is essential to slow disease progression and improve overall health, as most patients will die of cirrhosis, cardiovascular disease or smoking related cancers rather than chronic pancreatitis. The socioeconomic impact of chronic pancreatitis is difficult to quantify as little data exists, however given the rising incidence the costs to health care and society are likely to increase. This chapter will describe the epidemiology and aetiology of chronic pancreatitis worldwide and discusses the factors that influence its socioeconomic impact.
