RESUMO
INTRODUCTION: Among children who suffer from acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP), acute pancreatitis (AP) episodes are painful, often require hospitalization, and contribute to disease complications and progression. Despite this recognition, there are currently no interventions to prevent AP episodes. In this retrospective cohort study, we assessed the impact of pancreatic enzyme therapy (PERT) use on clinical outcomes among children with pancreatic-sufficient ARP or CP. METHODS: Children with pancreatic-sufficient ARP or CP in the INSPPIRE-2 cohort were included. Clinical outcomes were compared for those receiving vs not receiving PERT, as well as frequency of AP before and after PERT. Logistic regression was used to study the association between development of AP episodes after starting PERT and response predictors. RESULTS: Among 356 pancreatic-sufficient participants, 270 (76%) had ARP, and 60 (17%) received PERT. Among those on PERT, 42% did not have a subsequent AP episode, during a mean 2.1 years of follow-up. Children with a SPINK1 mutation ( P = 0.005) and those with ARP (compared with CP, P = 0.008) were less likely to have an AP episode after starting PERT. After initiation of PERT, the mean AP annual incidence rate decreased from 3.14 down to 0.71 ( P < 0.001). DISCUSSION: In a retrospective analysis, use of PERT was associated with a reduction in the incidence rate of AP among children with pancreatic-sufficient ARP or CP. These results support the need for a clinical trial to evaluate the efficacy of PERT to improve clinical outcomes among children with ARP or CP.
RESUMO
OBJECTIVES: Abdominal pain, emergency department visits, and hospitalizations impact lives of children with acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP). Data on health-related quality of life (HRQOL) in this population, however, remains limited. We aimed to evaluate HRQOL in children with ARP or CP; and test biopsychosocial risk factors associated with low HRQOL. METHODS: Data were acquired from the INternational Study Group of Pediatric Pancreatitis: In search for a cuRE registry. Baseline demographic and clinical questionnaires, the Child Health Questionnaire (measures HRQOL) and Child Behavior Checklist (measures emotional and behavioral functioning) were completed at enrollment. RESULTS: The sample included 368 children (54.3% girls, mean ageâ=â12.7years, standard deviation [SD]â=â3.3); 65.2% had ARP and 34.8% with CP. Low physical HRQOL (Mâ=â38.5, SDâ=â16.0) was demonstrated while psychosocial HRQOL (Mâ=â49.5, SDâ=â10.2) was in the normative range. Multivariate regression analysis revealed that clinical levels of emotional and behavioral problems (Bâ=â-10.28, Pâ <â0.001), episodic and constant abdominal pain (Bâ=â04.66, Pâ=â0.03; Bâ=â-13.25, Pâ<â0.001) were associated with low physical HRQOL, after accounting for ARP/CP status, age, sex, exocrine, and endocrine disease (F [9, 271]â=â8.34, Pâ<â0.001). Borderline and clinical levels of emotional and behavioral problems (Bâ=â-10.18, Pâ<â0.001; Bâ=â-15.98, Pâ<â0.001), and constant pain (Bâ=â-4.46, Pâ<â0.001) were associated with low psychosocial HRQOL (F [9, 271]â=â17.18, Pâ<â0.001). CONCLUSIONS: Findings highlight the importance of assessing HRQOL and treating pain and psychosocial problems in this vulnerable group of children.

Objective: To describe management strategies that contributed to optimal outcomes in pediatric recipients of a total pancreatectomy with islet autotransplantation (TPIAT). Research Design and Methods: We provide a comprehensive report of the approach to endocrine management of the pediatric TPIAT recipient from initial evaluation through the first 4 years postsurgery. We performed a retrospective review of the endocrine outcomes of TPIAT recipients to describe the impact of this approach on post-TPIAT glycemic management. Results: Outcome data from 86 TPIAT recipients were reviewed. At 12 months post-TPIAT (n = 82), the median HbA1C was 6.0% (25-75th percentile 5.6-6.7), at 18 months (n = 56) HbA1C was 6.4% (5.6-7.5), at 2 years (n = 46) HbA1C was 6.4% (5.6-7.4), at 3 years (n = 31) HbA1C was 6.5% (5.5-8.1), and at 4 years (n = 16) HbA1C was 7.2% (6.2-8.3). Conclusions: Pediatric patients at our institution have favorable endocrine outcomes as evidenced by median HbA1C under the goal of 6.5% through the initial 3 years by following our modified management protocols.

Circulating microRNAs (miRNAs) can be biomarkers for diagnosis and progression of several pathophysiological conditions. In a cohort undergoing total pancreatectomy with islet autotransplantation (TPIAT) from the multicenter Prospective Observational Study of TPIAT (POST), we investigated associations between a panel of circulating miRNAs (hsa-miR-375, hsa-miR-29b-3p, hsa-miR-148a-3p, hsa-miR-216a-5p, hsa-miR-320d, hsa-miR-200c, hsa-miR-125b, hsa-miR-7-5p, hsa-miR-221-3p, hsa-miR-122-5p) and patient, disease and islet-isolation characteristics. Plasma samples (n = 139) were collected before TPIAT and miRNA levels were measured by RTPCR. Disease duration, prior surgery, and pre-surgical diabetes were not associated with circulating miRNAs. Levels of hsa-miR-29b-3p (P = 0.03), hsa-miR-148a-3p (P = 0.04) and hsa-miR-221-3p (P = 0.01) were lower in those with genetic risk factors. Levels of hsa-miR-148a-3p (P = 0.04) and hsa-miR-7-5p (P = 0.04) were elevated in toxic/metabolic disease. Participants with exocrine insufficiency had lower hsa-miR-29b-3p, hsa-miR-148a-3p, hsa-miR-320d, hsa-miR-221-3p (P < 0.01) and hsa-miR-375, hsa-miR-200c-3p, and hsa-miR-125b-5p (P < 0.05). Four miRNAs were associated with fasting C-peptide before TPIAT (hsa-miR-29b-3p, r = 0.18; hsa-miR-148a-3p, r = 0.21; hsa-miR-320d, r = 0.19; and hsa-miR-221-3p, r = 0.21; all P < 0.05), while hsa-miR-29b-3p was inversely associated with post-isolation islet equivalents/kg and islet number/kg (r = -0.20, P = 0.02). Also, hsa-miR-200c (r = 0.18, P = 0.03) and hsa-miR-221-3p (r = 0.19, P = 0.03) were associated with islet graft tissue volume. Further investigation is needed to determine the predictive potential of these miRNAs for assessing islet autotransplant outcomes.

OBJECTIVES: A selective therapy for pancreatitis is total pancreatectomy and islet autotransplantation. Outcomes and geographical variability of patients who had total pancreatectomy (TP) alone or total pancreatectomy with islet autotransplantation (TPIAT) were assessed. METHODS: Data were obtained from the Healthcare Cost and Utilization Project National Inpatient Sample database. Weighed univariate and multivariate analyses were performed to determine the effect of measured variables on outcomes. RESULTS: Between 2002 and 2013, there were 1006 TP and 825 TPIAT in patients with a diagnosis of chronic pancreatitis, and 1705 TP and 830 TPIAT for any diagnosis of pancreatitis. The majority of the TP and TPIAT were performed in larger urban hospitals. Costs were similar for TP and TPIAT for chronic pancreatitis but were lower for TPIAT compared with TP for any type of pancreatitis. The trend for TP and TPIAT was significant in all geographical areas during the study period. CONCLUSIONS: There is an increasing trend of both TP and TPIAT. Certain groups are more likely to be offered TPIAT compared with TP alone. More data are needed to understand disparities and barriers to TPIAT, and long-term outcomes of TPIAT such as pain control and glucose intolerance need further study.

BACKGROUND: Intestinal failure is a chronic condition related to loss of bowel length and/or function, resulting in dependence on central venous catheters for fluids and nutrition. Catheter use can be associated with significant complications, including catheter-related bloodstream infections (CRBSIs), which can lead to loss of vascular access, advancing intestinal failure associated-liver disease and death. Our objective was to evaluate the effectiveness and safety of ethanol locks as compared with standard heparin locks in pediatric intestinal failure. METHODS: Databases, including MEDLINE and EMBASE, were searched until March 2017. Titles and abstracts were reviewed independently and relevant articles reassessed by full-text review. The main outcome was the rate of CRBSIs, while secondary outcomes were catheter replacement and repair. RESULTS: Nine observational studies were included. The mean difference in rate of CRBSIs was 6.27 per 1000 catheter days (95% CI, 4.89-7.66) favoring ethanol locks, with a 63% overall reduction in infection rate. The mean difference in catheter replacement rate (per 1000 catheter days) was 4.56 (95% Cl, 2.68-6.43) favoring ethanol locks. The overall effect on catheter repair rate (per 1000 catheter days) was -1.67 (95% CI, -2.30 to -1.05), indicating lower repair rate with heparin locks. CONCLUSION: Sufficient evidence was noted showing that ethanol locks reduced CRBSIs and catheter replacements. Our findings raise questions about the effect of the ethanol lock on catheter integrity based on the noted increase in repair rate. This requires further prospective evaluation and may support selective application of ethanol locks to patients with documented CRBSIs.

Salmonella species are a group of Gram-negative enterobacteria and known human pathogens in developing as well as industrialized countries. Despite significant advances in sanitation, provision of potable water, and highly controlled food chain surveillance, transmission of Salmonella spp. continues to affect communities, preferentially children, worldwide. This review summarizes updated concepts on typhoidal and non-typhoidal Salmonella infections, starting with a historical perspective that implicates typhoid Salmonella as a significant human pathogen since ancient times. We describe the epidemiology of this pathogen with emphasis on the most recent non-typhoidal Salmonella outbreaks in industrialized countries and continued outbreaks of typhoid Salmonella in underserved countries. An overview of clinical aspects of typhoid and non-typhoid infections in developing and industrialized countries, respectively, is provided, followed by a description on current treatment concepts and challenges treating multidrug-resistant Salmonella infections. We conclude with prevention recommendations, and recent research studies on vaccine prevention.
