Abstract
Introduction Acute pancreatitis (AP) is characterised by an inflammatory response that in its most severe form can cause a systemic dysregulated immune response and progression to acute multi-organ dysfunction. The pathobiology of the disease is unclear and as a result no targeted, disease-modifying therapies exist. We performed a scoping review of data pertaining to the human immunology of AP to summarise the current field and to identify future research opportunities. Methods A scoping review of all clinical studies of AP immunology was performed across multiple databases. Studies were included if they were human studies of AP with an immunological outcome or intervention. Results 205 studies met the inclusion criteria for the review. Severe AP is characterised by significant immune dysregulation compared to the milder form of the disease. Broadly, this immune dysfunction was categorised into: innate immune responses (including profound release of damage-associated molecular patterns and heightened activity of pattern recognition receptors), cytokine profile dysregulation (particularly IL-1, 6, 10 and TNF-α), lymphocyte abnormalities, paradoxical immunosuppression (including HLA-DR suppression and increased co-inhibitory molecule expression), and failure of the intestinal barrier function. Studies including interventions were also included. Several limitations in the existing literature have been identified; consolidation and consistency across studies is required if progress is to be made in our understanding of this disease. Conclusions AP, particularly the more severe spectrum of the disease, is characterised by a multifaceted immune response that drives tissue injury and contributes to the associated morbidity and mortality. Significant work is required to develop our understanding of the immunopathology of this disease if disease-modifying therapies are to be established.

High-volume hemofiltration reduces short-term mortality with no influence on the incidence of MODS, hospital stay, and hospitalization cost in patients with severe-acute pancreatitis: A meta-analysis. Artif Organs 2021; 45:1456-1465. [PMID: 34240469 DOI: 10.1111/aor.14016] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 05/08/2021] [Accepted: 06/15/2021] [Indexed: 12/22/2022]
Abstract
This study aimed to investigate the efficiency, safety and cost-efficiency of blood purification (BP) in treating patients with severe-acute pancreatitis (SAP). A literature search was conducted using PubMed, OVID, International Clinical Trials Register (ICTRP), and Cochrane Central Register of Controlled Trials (CENTRAL). A total of 11 prospective studies and 6 retrospective studies, which reported the mortality of 1279 SAP patients, were included for analysis. Decreased short-term mortality and incidence rate of infection were observed in the high-volume hemofiltration (HVHF) group, but not in patients treated with other types of BP. There was no significant difference in the incidence of multiple-organ dysfunction (MODS), duration of hospital stay, or cost of hospitalization between the BP and non-BP groups. The starting time point, substitution fluid flow rate, filter membrane type, hemofilter change interval, anticoagulation, and sustaining times of BP varied across studies. In conclusion, HVHF may reduce the short-term mortality (<4 weeks), not long-term mortality, of SAP patients by decreasing the incidence of infection, while other types of BP did not show a significant beneficial effect. Neither HVHF nor other BP patterns affect the duration of hospital stay, cost of hospitalization, or incidence of MODS in SAP patients.

Abstract
Background The treatment of high-grade (III/IV/V) blunt pancreatic injuries remains controversial. The study aims to summarize and evaluate nonresection management of the pancreas for grade III and IV blunt pancreatic injuries in children. Methods Twenty children [6.9 (3–12) years] treated at our center between January 2010 and June 2018 were included in this study. Their medical records and the outpatient follow-up data within 12 weeks after discharge were retrospectively reviewed. Long-term follow-up was conducted by telephone in February 2020. Results Nine children developed complications, including 8 pancreatic pseudocysts and 1 abdominal infection, after treatment at external hospitals and were transferred to our center with an average length of stay of 33.8 (8–63) days. Eleven children were admitted to our hospital directly after injury, with an average length of stay of 47.5 (23–69) days. One child underwent emergency laparotomy for hemorrhagic shock and Roux-en-Y drainage of the distal pancreas. The remaining 10 children received conservative treatment: 7 developed pancreatic pseudocysts, 2 developed abdominal infections, and 1 recovered uneventfully. For children with pancreatic pseudocysts (15/20, 75.0%), 4 recovered after conservative treatment, 4 recovered after percutaneous puncture, 5 recovered after external drainage of the cyst, and 2 recovered after alimentary tract anastomosis. Three children (3/20, 15.0%) who developed abdominal infection recovered after abdominal irrigation and drainage. No child was admitted to the ICU or died. Four children (4/20, 20.0%) developed local pancreatic atrophy within 12 weeks after discharge, but no other long-term complications were observed. Conclusions Nonresection management of the pancreas could be a feasible option for children with grade III and IV blunt pancreatic injuries. Regular long-term follow-up is essential in terms of pancreatic function, especially in patients with pancreatic atrophy.

Abstract
Acute pancreatitis (AP) is the most frequent gastrointestinal cause for hospitalization and one of the leading causes of in-hospital deaths. Severe acute pancreatitis is often associated with multiorgan failure and especially with acute kidney injury (AKI). AKI can develop early or late in the course of the disease and is a strong determinator of outcome. The mortality in the case of dialysis-dependent AKI and acute pancreatitis raises exponentially in the affected patients. AP-induced AKI (AP-AKI) shows many similarities but also distinct differences to other causes of AKI occurring in the intensive care unit setting. The knowledge of the exact pathophysiology can help to adjust, control and improve therapeutic approaches to the disease. Unfortunately, there are only a few studies dealing with AP and AKI.In this review, we discuss recent data about pathogenesis, causes and management of AP-AKI in patients with severe acute pancreatitis and exploit in this regard the diagnostic and prognostic potential of respective newer serum and urine markers.

Continuous Hemofiltration Reduces Mortality in Severe Acute Pancreatitis: A Meta-Analysis. Emerg Med Int 2020; 2020:6474308. [PMID: 32670639 PMCID: PMC7341416 DOI: 10.1155/2020/6474308] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Revised: 03/20/2020] [Accepted: 04/27/2020] [Indexed: 12/22/2022] Open
Abstract
Background Severe acute pancreatitis (SAP) is a deadly condition, with a mortality rate ranging from 15% to 30%. Recently, blood purification therapy has been adopted in administrating SAP patients. The present study aimed at evaluating the effect of continuous hemofiltration therapy for SAP. Methods A systematic search of Cochrane Library, PubMed, and Embase was carried out until October 1st, 2019. Prospective studies comparing outcomes for SAP patients between continuous hemofiltration and standard therapy were enrolled. Results Continuous hemofiltration therapy was associated with lower level of PACHE II score (MD = −1.49; 95% CI: −2.69 to −0.29, P=0.02), CRP (MD = −1.56 mg/L; 95% CI: −2.64 to −0.47, P=0.005), Cr (MD = −3.57 umol/L; 95% CI: −5.50 to −1.65, P=0.003), and Bun (MD = −3.63 mmol/L; 95% CI: −6.07 to −1.20, P=0.003) at 72 h after onset of treatment. Continuous hemofiltration therapy was associated with shorter length of abdominal pain relief time (MD = −1.82 hours; 95% CI: −2.93 to −0.71, P=0.001), lower surgery rate (OR = 0.15; 95% CI: 0.03 to 0.78, P=0.02), and mortality rate (OR = 0.54; 95% CI: 0.37 to 0.77, P=0.0007). Conclusions continuous hemofiltration therapy could effectively alleviate SAP as early as 72 hours after onset of treatment, lowering the level of Bun, Cr, CRP, and APACHE II scores. Continuous hemofiltration therapy could confer SAP patients with lower mortality rates.

Abstract
Background The efficacy of some therapeutic methods (open surgical debridement (OSD), conservative treatment (CST) and minimally invasive drainage (MID)) for severe acute pancreatitis (SAP) and moderately severe acute pancreatitis (MSAP) has been widely evaluated. However, the results remained controversial. We performed this study to illuminate whether any difference in incidence exists on patients with SAP/MSAP treated with OSD and MID. Methods Eligible articles were collected base of a comprehensive review of PUBMED, EMBASE, COCHRANE, CKNI and WANGFANG for published randomized controlled trials. Two steps of meta-analysis were performed, routine pair-wise meta-analysis and network meta-analysis. Results Thirteen studies were included in this study. Participants were classed as 5 groups, CST, early MID (EMID), late MID (LMID), early OSD (EOSD) and late OSD (LOSD). And MID contains endoscopic drainage (ESD), percutaneous catheter drainage (PCD) and minimally invasive surgery (MIS). Compared with CST, MID could decrease both mortality and multiple organ dysfunction syndrome (MODS) rate but OSD couldn’t. Both EMID and MID can significantly decrease the mortality and MODS rate compared to CST. PCD might be most likely to have a benefit compared to CST. Conclusion Existing evidence for the use of MID in SAP/MSAP is reliable and it can be used as early treatment. OSD, if necessary, should be avoided or delayed as long as possible.

Abstract
BACKGROUND Severe acute pancreatitis is associated with high rates of mortality and life-threatening complications. Continuous veno-venous hemofiltration (CVVH) has been used in some centers to reduce mortality and avoid local or systemic complications, however its efficiency and safety is uncertain. OBJECTIVES To assess the benefits and harms of CVVH in patients suffering from severe acute pancreatitis; to compare the effects of different CVVH techniques; and to evaluate the optimal time for delivery of CVVH. SEARCH METHODS We searched the Cochrane Library (2019, Issue 8), MEDLINE (1946 to 13 September 2019), Embase (1974 to 13 September 2019), and Science Citation Index Expanded (1982 to 13 September 2019). SELECTION CRITERIA We included all randomized controlled trials (RCTs) that compared CVVH versus no CVVH in participants with severe acute pancreatitis. We also included RCTs that compared different types of CVVH and different schedules for CVVH in participants with severe acute pancreatitis. DATA COLLECTION AND ANALYSIS Two review authors independently identified the trials for inclusion, collected the data, and assessed the risk of bias. We performed the meta-analyses using Review Manager 5. We calculated the risk ratio (RR) for dichotomous outcomes, and the mean difference (MD) for continuous outcomes, with 95% confidence intervals (CIs). MAIN RESULTS We included two studies, involving a total of 94 participants, in the review.Continuous veno-venous hemofiltration versus no interventionWe included one study in which 64 participants with severe acute pancreatitis were randomized to undergo CVVH (32 participants) or no intervention (32 participants). There were no deaths in either group (very low-quality evidence). Adverse events, length of stay in the intensive care unit (ICU), length of hospital stay, total hospital cost, and quality of life were not reported in the study.One type of continuous veno-venous hemofiltration versus a different type of continuous veno-venous hemofiltrationWe included one study in which 30 participants with severe acute pancreatitis were randomized to undergo high-volume CVVH (15 participants) or standard CVVH (15 participants). High-volume CVVH may lead to little or no difference in in-hospital mortality rates (20.0% in the high-volume CVVH group versus 33.3% in the standard CVVH group; risk ratio (RR) 0.60, 95% confidence interval (CI) 0.17 to 2.07; 30 participants; 1 study; low-quality evidence). We are uncertain whether high-volume hemofiltration reduces rates of adverse events (13.3% in both groups; RR 1.00, 95% CI 0.16 to 6.20; 30 participants; 1 study; very low-quality evidence). Length of ICU stay, length of hospital stay, total hospital cost, and quality of life were not reported in the study. AUTHORS' CONCLUSIONS The quality of the current evidence is very low or low. For both comparisons addressed in this review, data are sparse. It is unclear whether CVVH has any effect on mortality or complications in patients with severe acute pancreatitis. It is also unclear whether high-volume CVVH is superior, equivalent or inferior to standard CVVH in patients with severe acute pancreatitis.

Abstract
BACKGROUND The incidence of acute pancreatitis (AP) is rising around the world, thus further increasing the burden on healthcare services. Approximately 20% of AP will develop severe acute pancreatitis (SAP) with persistent organ failure (>48 h), which is the leading cause of high mortality. To date, there is no specific drug in treating SAP, and the main treatment is still based on supportive care. However, some clinical control studies regarding the superiority of continuous blood purification (CBP) has been published recently. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy of CBP in SAP treatment. METHODS Four databases (Medline, SinoMed, EMBASE, and Cochrane Library) were searched for eligible studies from 1980 to 2018 containing a total of 4 randomized controlled trials and 8 prospective studies. RESULTS After the analysis of data amenable to polling, significant advantages were found in favor of the CBP approach in terms of Acute Physiology and Chronic Health Evaluation II (APACHE II) score (WMD = -3.00,95%CI = -4.65 to -1.35), serum amylase (WMD = -237.14, 95% CI = -292.77 to 181.31), serum creatinine (WMD = -80.54,95%CI = 160.17 to -0.92), length of stay in the ICU (WMD = -7.15,95%CI = -9.88 to -4.43), and mortality (OR = 0.60, 95%CI = 0.38-0.94). No marked differences were found in terms of C-reactive protein (CRP), alamine aminotransferase (ALT) and length of hospital stay (LOS). CONCLUSION Compared with conventional treatment, CBP remedy evidently improved clinical outcomes, including reduced incidence organ failure, decreased serum amylase, APACHE II score, length of stay in the ICU and lower mortality rate, leading us to conclude that it is a safer treatment option for SAP. Furthermore, relevant multicenter RCTs are required to prove these findings.
