Sarri G, Guo Y, Iheanacho I, Puelles J. Moderately severe and severe acute pancreatitis : a systematic review of the outcomes in the USA and European Union-5. BMJ Open Gastroenterol 2019; 6:e000248. [PMID: 30899535 PMCID: PMC6398872 DOI: 10.1136/bmjgast-2018-000248] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2018] [Revised: 12/13/2018] [Accepted: 12/24/2018] [Indexed: 01/07/2023] Open
Abstract
Background and objectives The global incidence of hospitalisation due to acute pancreatitis (AP) has been rising in the recent decades. In the USA alone, there was a 13.2% increase between 2009 and 2012 compared with 2002–2005. There remains a lack of approved treatments to prevent disease progression, leaving many liable to developing complications that include multisystem organ failure (OF) and death. This therapeutic deficit raises questions about the scale of the current burden of illness (BOI) associated with severe forms of AP. The aim of the systematic literature review (SLR) was to assess clinical, humanistic, and economic outcomes associated with moderately severe AP (MSAP) and severe AP (SAP) in the USA and the European Union-5 (EU-5). Methods Systematic searches were conducted in MEDLINE and Embase to identify studies published in English (between 2007 and 2017) that reported on the BOI of MSAP and/or SAP. Manual searches of ‘grey’ literature sources were also conducted. Results The SLR identified 19 studies which indicated that 15%–20% of patients with AP progress to more severe forms of the disease, up to 10.5% of those with SAP require surgery for complications, and up to 40% die during hospitalisation. By contrast, there appears to be a lack of data on the extent to which SAP affects patients’ quality of life. Conclusion The available evidence clearly demonstrates that the current management for MSAP and SAP in the USA and EU-5 does not adequately meet patients’ needs. Early identification and intervention for AP is crucial, given the evidence of high rates of morbidity and an associated economic burden that is considerable. Since many patients with the condition present to hospitals at a point when multisystem OF or death is highly likely, there is a particularly urgent need for effective treatment options to prevent disease progression.

Abstract
OBJECTIVES Genetic testing could play a critical role in diagnosis and prognosis of acute pancreatitis (AP) and guide effective therapeutic interventions. We hypothesized that genetic polymorphisms in apoptosis and oxidative stress genes could determine incidence or severity in AP. METHODS We conducted a hospital-based case-control study in a white Portuguese population (133 AP patients and 232 age- and sex-matched healthy controls) to evaluate the role of 15 gene polymorphisms (2 deletions and 13 single nucleotide polymorphisms [SNPs]) in oxidative stress (GSTM1, GSTT1, GSTP1) and apoptosis genes (CASP7, CASP8, CASP9, CASP10, LTA, TNFRSF1B, TP53) in AP. Criteria for AP were abdominal pain, hyperamylasemia, and contrast-enhanced computed tomography. RESULTS The presence of GSTM1 is associated with increased susceptibility for AP, and the GSTP1 Val105Ile SNP is associated with an increased risk for AP in men. CASP9 Phe136Leu/Phe136Phe SNPs (heterozygotes) increases the risk for mild AP (odds ratio, 3.616; 95% confidence interval, 1.151-11.364; P < 0.05), whereas the homozygotic genotype of CASP9 Ala28Val decreases risk for mild AP (odds ratio, 0.296; 95% confidence interval, 0.091-0.963; P < 0.05). CONCLUSIONS Our results suggest that variations in GSTM1, GSTP1, and CASP9 may influence risk for AP.

Abstract
Acute pancreatitis (AP) is a common clinical condition with an incidence of about 300 or more patients per million annually. About 10%-15% of patients will develop severe acute pancreatitis (SAP) and of those, 10%-30% may die due to SAP-associated complications. Despite the improvements done in the diagnosis and management of AP, the mortality rate has not significantly declined during the last decades. Toll-like receptors (TLRs) are pattern-recognition receptors that seem to play a major role in the development of numerous diseases, which make these molecules attractive as potential therapeutic targets. TLRs are involved in the development of the systemic inflammatory response syndrome, a potentially lethal complication in SAP. In the present review, we explore the current knowledge about the role of different TLRs that have been described associated with AP. The main candidate for targeting seems to be TLR4, which recognizes numerous damage-associated molecular patterns related to AP. TLR2 has also been linked with AP, but there are only limited studies that exclusively studied its role in AP. There is also data suggesting that TLR9 may play a role in AP.

-651C/T promoter polymorphism in the CD14 gene is associated with severity of acute pancreatitis in Japan. J Gastroenterol 2010; 45:225-33. [PMID: 19997857 DOI: 10.1007/s00535-009-0163-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2009] [Accepted: 11/05/2009] [Indexed: 02/04/2023]
Abstract
PURPOSE This study aimed to clarify the association of the promoter variants in the CD14 gene with pancreatic diseases in Japan. METHODS Three hundred forty-six unrelated patients with acute pancreatitis (AP) (107 with severe and 239 with mild), 263 patients with chronic pancreatitis (CP), 264 patients with pancreatic neoplasm, and 319 healthy controls were genotyped for the single nucleotide polymorphisms at positions -260 and -651 from the AUG start codon in the CD14 gene by polymerase chain reaction-restriction enzyme digestion. RESULTS The allele and genotype frequencies of the -260C/T and -651C/T polymorphisms did not differ between controls and patients with AP. In subgroup analyses, patients with severe AP had more -651C allele than controls [P = 0.005; odds ratio (OR) 1.71; 95% confidence interval (CI) = 1.18-2.49] or patients with mild AP (P = 0.001; OR 1.95; 95% CI = 1.33-2.85). Genotype -651CC was more common (P = 0.001 vs. controls and P = 0.001 vs. mild AP), and -651CT was less (P = 0.009 vs. controls and P = 0.007 vs. mild AP) in patients with severe AP than in healthy controls or patients with mild AP. The frequencies of pseudocyst development and requirement of surgery were higher in AP patients with -651CC than in those without this genotype. The -260C/T polymorphism was not associated with the severity of AP. The allele and genotype frequencies of both polymorphisms did not differ between controls and patients with CP or pancreatic neoplasm. CONCLUSION -651C/T promoter polymorphism in the CD14 gene was associated with severity of AP in Japan.

Abstract
This study evaluated the association of the polymorphisms in the Toll-like receptor (TLR)2 and TLR4 genes with acute pancreatitis (AP) in Japan. The numbers of guanine-thymine [(GT)n] repeats in intron 2 of the TLR2 gene were counted in 202 unrelated patients with AP (80 with severe and 122 with mild disease) and in 286 healthy controls, using polymerase chain reaction and Genescan analysis. The alleles were divided into three subclasses: (GT)16 or less as the S allele; between (GT)17 and (GT)22 as the M allele; and (GT)23 or more as the L allele. Asp299Gly and Thr399Ile polymorphisms in the TLR4 gene were examined by polymerase chain reaction-restriction fragment length polymorphism analysis. Patients with AP had more S alleles (p < 0.001; odds ratio = 2.37; 95% confidence interval = 1.78-3.17) and fewer M alleles (p < 0.001; odds ratio = 0.40; 95% confidence interval 0.31-0.52) than did healthy controls. Genotypes SS and SL were more common, whereas MM and ML were less common in patients with AP. In subgroup analyses, the genotypes including S alleles were more common in patients with severe AP than in controls. No Asp299Gly and Thr399Ile polymorphisms were detected. In conclusion, microsatellite polymorphism in intron 2 of the TLR2 gene was associated with susceptibility to AP and its severity in Japan.

Abstract
Reactive oxygen and reactive nitrogen species (ROS/RNS) have been implicated in the pathogenesis of acute and chronic pancreatitis. Clinical and basic science studies have indicated that ROS/RNS formation processes are intimately linked to the development of the inflammatory disorders. The detrimental effects of highly reactive ROS/RNS are mediated by their direct actions on biomolecules (lipids, proteins, and nucleic acids) and activation of proinflammatory signal cascades, which subsequently lead to activation of immune responses. The present article summarizes the possible sources of ROS/RNS formation and the detailed signaling cascades implicated in the pathogenesis of pancreatic inflammation, as observed in acute and chronic pancreatitis. A therapeutic ROS/RNS-scavenging strategy has been advocated for decades; however, clinical studies examining such approaches have been inconsistent in their results. Emerging evidence indicates that pancreatitis-inducing ROS/RNS generation may be attenuated by targeting ROS/RNS-generating enzymes and upstream mediators.

Abstract
BACKGROUND Recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) are complex syndromes associated with numerous etiologies, clinical variables and complications. We developed the North American Pancreatitis Study 2 (NAPS2) to be sufficiently powered to understand the complex environmental, metabolic and genetic mechanisms underlying RAP and CP. METHODS Between August 2000 and September 2006, a consortium of 20 expert academic and private sites prospectively ascertained 1,000 human subjects with RAP or CP, plus 695 controls (spouse, family, friend or unrelated). Standardized questionnaires were completed by both the physicians and study subjects and blood was drawn for genomic DNA and biomarker studies. All data were double-entered into a database and systematically reviewed to minimize errors and include missing data. RESULTS A total of 1,000 subjects (460 RAP, 540 CP) and 695 controls who completed consent forms and questionnaires and donated blood samples comprised the final dataset. Data were organized according to diagnosis, supporting documentation, etiological classification, clinical signs and symptoms (including pain patterns and duration, and quality of life), past medical history, family history, environmental exposures (including alcohol and tobacco use), medication use and therapeutic interventions. Upon achieving the target enrollment, data were organized and classified to facilitate future analysis. The approaches, rationale and datasets are described, along with final demographic results. CONCLUSION The NAPS2 consortium has successfully completed a prospective ascertainment of 1,000 subjects with RAP and CP from the USA. These data will be useful in elucidating the environmental, metabolic and genetic conditions, and to investigate the complex interactions that underlie RAP and CP.
