Meta-Analysis Review
BACKGROUND
Pancreatic necrosis may complicate severe acute pancreatitis, and is detectable by computed tomography (CT). If it becomes infected mortality increases, but the use of prophylactic antibiotics raises concerns about antibiotic resistance and fungal infection.
OBJECTIVES
To determine the efficacy and safety of prophylactic antibiotics in acute pancreatitis complicated by CT proven pancreatic necrosis.
SEARCH STRATEGY
Searches were updated in November 2008, in The Cochrane Library (Issue 2, 2008), MEDLINE, EMBASE, and CINAHL. Conference proceedings and references from found articles were also searched.
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing antibiotics versus placebo in acute pancreatitis with CT proven necrosis.
DATA COLLECTION AND ANALYSIS
Primary outcomes were mortality and pancreatic infection rates. Secondary end-points included non pancreatic infection, all sites infection, operative rates, fungal infections, and antibiotic resistance. Subgroup analyses were performed for antibiotic regimen (beta-lactam, quinolone, and imipenem).
MAIN RESULTS
Seven evaluable studies randomised 404 patients. There was no statistically significant effect on reduction of mortality with therapy: 8.4% versus controls 14.4%, and infected pancreatic necrosis rates: 19.7% versus controls 24.4%. Non-pancreatic infection rates and the incidence of overall infections were not significantly reduced with antibiotics: 23.7% versus 36%; 37.5% versus 51.9% respectively. Operative treatment and fungal infections were not significantly different. Insufficient data were provided concerning antibiotic resistance.With beta-lactam antibiotic prophylaxis there was less mortality (9.4% treatment, 15% controls), and less infected pancreatic necrosis (16.8% treatment group, 24.2% controls) but this was not statistically significant. The incidence of non-pancreatic infections was non-significantly different (21% versus 32.5%), as was the incidence of overall infections (34.4% versus 52.8%), and operative treatment rates. No significant differences were seen with quinolone plus imidazole in any of the end points measured. Imipenem on its own showed no difference in the incidence of mortality, but there was a significant reduction in the rate of pancreatic infection (p=0.02; RR 0.34, 95% CI 0.13 to 0.84).
AUTHORS' CONCLUSIONS
No benefit of antibiotics in preventing infection of pancreatic necrosis or mortality was found, except for when imipenem (a beta-lactam) was considered on its own, where a significantly decrease in pancreatic infection was found. None of the studies included in this review were adequately powered. Further better designed studies are needed if the use of antibiotic prophylaxis is to be recommended.

Meta-Analysis
RATIONALE & OBJECTIVE
Coronavirus disease 2019 (COVID-19) disproportionately affects people with chronic diseases such as chronic kidney disease (CKD). We assessed the incidence and outcomes of COVID-19 in people with CKD.
STUDY DESIGN
Systematic review and meta-analysis by searching MEDLINE, EMBASE, and PubMed through February 2021.
SETTING & STUDY POPULATIONS
People with CKD with or without COVID-19.
SELECTION CRITERIA FOR STUDIES
Cohort and case-control studies.
DATA EXTRACTION
Incidences of COVID-19, death, respiratory failure, dyspnea, recovery, intensive care admission, hospital admission, need for supplemental oxygen, hospital discharge, sepsis, short-term dialysis, acute kidney injury, and fatigue.
ANALYTICAL APPROACH
Random-effects meta-analysis and evidence certainty adjudicated using an adapted version of GRADE (Grading of Recommendations Assessment, Development and Evaluation).
RESULTS
348 studies (382,407 participants with COVID-19 and CKD; 1,139,979 total participants with CKD) were included. Based on low-certainty evidence, the incidence of COVID-19 was higher in people with CKD treated with dialysis (105 per 10,000 person-weeks; 95% CI, 91-120; 95% prediction interval [PrI], 25-235; 59 studies; 468,233 participants) than in those with CKD not requiring kidney replacement therapy (16 per 10,000 person-weeks; 95% CI, 4-33; 95% PrI, 0-92; 5 studies; 70,683 participants) or in kidney or pancreas/kidney transplant recipients (23 per 10,000 person-weeks; 95% CI, 18-30; 95% PrI, 2-67; 29 studies; 120,281 participants). Based on low-certainty evidence, the incidence of death in people with CKD and COVID-19 was 32 per 1,000 person-weeks (95% CI, 30-35; 95% PrI, 4-81; 229 studies; 70,922 participants), which may be higher than in people with CKD without COVID-19 (incidence rate ratio, 10.26; 95% CI, 6.78-15.53; 95% PrI, 2.62-40.15; 4 studies; 18,347 participants).
LIMITATIONS
Analyses were generally based on low-certainty evidence. Few studies reported outcomes in people with CKD without COVID-19 to calculate the excess risk attributable to COVID-19, and potential confounders were not adjusted for in most studies.
CONCLUSIONS
The incidence of COVID-19 may be higher in people receiving maintenance dialysis than in those with CKD not requiring kidney replacement therapy or those who are kidney or pancreas/kidney transplant recipients. People with CKD and COVID-19 may have a higher incidence of death than people with CKD without COVID-19.

Review
Colistimethate sodium powder and tobramycin powder for inhalation for the treatment of chronic Pseudomonas aeruginosa lung infection in cystic fibrosis: systematic review and economic model.
BACKGROUND
Cystic fibrosis (CF) is an inherited condition characterised by the abnormal transport of chloride ions across transporting epithelia. This leads to the production of thick sticky mucus in the lungs, pancreas, liver, intestine and reproductive tract, and an increase in the salt content in sweat. Among other problems, people with CF experience recurrent respiratory infections and have difficulties digesting food. CF affects over 9000 individuals in the UK. CF shortens life expectancy and adversely affects quality of life. In 2010, CF was recorded as the cause of 103 deaths in England and Wales.
OBJECTIVE
To evaluate the clinical effectiveness and cost-effectiveness of colistimethate sodium dry powder for inhalation (DPI) (Colobreathe(®), Forest Laboratories) and tobramycin DPI (TOBI Podhaler(®), Novartis Pharmaceuticals) for the treatment of Pseudomonas aeruginosa lung infection in CF.
DATA SOURCES
Electronic databases were searched in February and March 2011 [MEDLINE, MEDLINE In-Process & Other Non-Indexed citations, EMBASE, The Cochrane Library databases, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Conference Proceedings Citation Index (CPCI) and Bioscience Information Service (BIOSIS) Previews]. Relevant databases were searched for ongoing and unpublished studies, and bibliographies of relevant systematic reviews and the manufacturers' submissions were also hand-searched.
REVIEW METHODS
A systematic review of the clinical effectiveness and cost-effectiveness of colistimethate sodium DPI and tobramycin DPI for the treatment of chronic P. aeruginosa lung infection in CF was conducted. Existing economic evidence within the literature was reviewed and a de novo health economic model was also developed.
RESULTS
Three randomised controlled trials (RCTs) were included in the clinical effectiveness review. Both colistimethate sodium DPI and tobramycin DPI were reported to be non-inferior to nebulised tobramycin for the outcome forced expiratory volume in first second percentage predicted (FEV1%). It was not possible to draw any firm conclusions as to the relative efficacy of colistimethate sodium DPI compared with tobramycin DPI. The economic analysis suggests that colistimethate sodium DPI produces fewer quality-adjusted life-years (QALYs) than nebulised tobramycin. Given the incremental discounted lifetime cost of tobramycin DPI compared with nebulised tobramycin, it highly unlikely that tobramycin DPI has an incremental cost-effectiveness ratio that is better than £30,000 per QALY gained.
LIMITATION
The uncertainty surrounding the short-term evidence base inevitably results in uncertainty surrounding the long-term clinical effectiveness and cost-effectiveness of colistimethate sodium DPI.
CONCLUSIONS
Both DPI formulations have been shown to be non-inferior to nebulised tobramycin as measured by FEV1%. The results of these trials should be interpreted with caution owing to the means by which the results were analysed, the length of follow-up, and concerns about the ability of FEV1% to accurately represent changes in lung health. Although the increase in QALYs is expected to be lower with colistimethate sodium DPI than with nebulised tobramycin, a price for this intervention had not been agreed at the time of the assessment. Depending on the price of colistimethate sodium DPI, this results either in a situation whereby colistimethate sodium DPI is dominated by nebulised tobramycin or in one whereby the incremental cost-effectiveness of nebulised tobramycin compared with colistimethate sodium DPI is in the range of £24,000-277,000 per QALY gained. The economic analysis also suggests that, given its price, it is unlikely that tobramycin DPI has a cost-effectiveness ratio of < £30,000 per QALY gained when compared with nebulised tobramycin. A RCT to assess the longer-term (≥ 12 months) efficacy of colistimethate sodium DPI and tobramycin DPI in comparison with nebulised treatments would be beneficial. Such a study should include the direct assessment of HRQoL using a relevant preference-based instrument. Future studies should ensure that the European Medicines Agency guidelines are adhered to. In addition, high-quality research concerning the relationship between forced expiratory volume in first second % (FEV1%) predicted or other measures of lung function and survival/health-related quality of life (HRQoL) would be useful.

Meta-Analysis Review
BACKGROUND
Pancreatic resections are associated with high morbidity (30% to 60%) and mortality (5%). Synthetic analogues of somatostatin are advocated by some surgeons to reduce complications following pancreatic surgery; however, their use is controversial.
OBJECTIVES
To determine whether prophylactic somatostatin analogues should be used routinely in pancreatic surgery.
SEARCH METHODS
We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 1), MEDLINE, EMBASE and Science Citation Index Expanded to February 2013.
SELECTION CRITERIA
We included randomised controlled trials comparing prophylactic somatostatin or one of its analogues versus no drug or placebo during pancreatic surgery (irrespective of language or publication status).
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion and independently extracted data. We analysed data with both the fixed-effect and random-effects models using Review Manager (RevMan). We calculated the risk ratio (RR), mean difference (MD) or standardised mean difference (SMD) with 95% confidence intervals (CI) based on an intention-to-treat or available case analysis. When it was not possible to perform either of the above, we performed a per protocol analysis.
MAIN RESULTS
We identified 21 trials (19 trials of high risk of bias) involving 2348 people. There was no significant difference in the perioperative mortality (RR 0.80; 95% CI 0.56 to 1.16; n = 2210) or the number of people with drug-related adverse effects between the two groups (RR 2.09; 95% CI 0.83 to 5.24; n = 1199). Quality of life was not reported in any of the trials. The overall number of participants with postoperative complications was significantly lower in the somatostatin analogue group (RR 0.70; 95% CI 0.61 to 0.80; n = 1903) but there was no significant difference in the re-operation rate (RR 1.26; 95% CI 0.58 to 2.70; n = 687) or hospital stay (MD -1.29 days; 95% CI -2.60 to 0.03; n = 1314) between the groups. The incidence of pancreatic fistula was lower in the somatostatin analogue group (RR 0.66; 95% CI 0.55 to 0.79; n = 2206). The proportion of these fistulas that were clinically significant was not mentioned in most trials. On inclusion of trials that clearly distinguished clinically significant fistulas, there was no significant difference between the two groups (RR 0.69; 95% CI 0.38 to 1.28; n = 292).
AUTHORS' CONCLUSIONS
Somatostatin analogues may reduce perioperative complications but do not reduce perioperative mortality. Further adequately powered trials with low risk of bias are necessary. Based on the current available evidence, somatostatin and its analogues are recommended for routine use in people undergoing pancreatic resection.

Meta-Analysis Review
OBJECTIVES
Induction immunosuppression for simultaneous pancreas-kidney transplant has helped reduce graft loss due to early rejection. Both thymoglobulin and interleukin 2 receptor antagonists are the most commonly used induction agents; however, some high-volume centers prefer alemtuzumab.Thisnetwork meta-analysis aimedto compare differentinductionregimens for simultaneouspancreaskidney transplantin terms ofbothpancreas and patient graft survival, as well to assess acute rejection.
MATERIALS AND METHODS
A systematic review was conducted to identify randomized clinical trials up to October 31, 2019, that examined induction regimens for simultaneous pancreas-kidney transplant. Study characteristics, postoperative data (patient, pancreas, and kidney graft survival), complications (eg, bleeding), infection rates, and malignancy rates were extracted. We compared all regimens using randomeffects network meta-analyses to maintain randomization within trials.
RESULTS
This study identified 7 randomized clinical trials that involved 536 patients, which reported 5 induction regimens. These regimens included antithymocyte globulin (97 patients), alemtuzumab (42 patients), 2 doses (113 patients) or 5 doses (164 patients) of daclizumab, and no induction therapy (120 patients). In the network meta-analysis, a regimen with 2 doses of daclizumab was consistently ranked first for patient survival and kidney and pancreas graft survival. In contrast, alemtuzumab was ranked best for acute rejection (both pancreas and kidney). Rates of majorinfection (ie, cytomegalovirus) and malignancy were reported in 3 studies, precluding a reliable analysis.
CONCLUSIONS
Daclizumab with 2 doses, given before simultaneous pancreas-kidney transplant, was associated with the best rates of patient and graft survival. Despite the recent withdrawal of daclizumab, an alternative anti-interleukin 2 induction regimen (basiliximab) has demonstrated promising results in nonrandomized series, warranting that further highquality large-scale randomized clinical trials are still needed.

Review
BACKGROUND
Emerging evidence has shown that two common genetic polymorphisms within the pleckstrin domain-containing protein 5 (DEPDC5), rs1012068 and rs5998152, may be associated with the risk of hepatocellular carcinoma (HCC), especially in those individuals chronically infected with the hepatitis C virus (HCV) or the hepatitis B virus (HBV). However, these findings have not been consistently replicated in the literature due to limited sample sizes or different etiologies of HCC. Thus, the present systematic review and meta-analysis were performed to resolve this inconsistency.
METHODS
The databases PubMed, Embase, Web of Science, the China National Knowledge Infrastructure, and Scopus were searched up to December 12, 2022. Data from relevant studies were pooled, and odds ratios and 95% confidence intervals were calculated.
RESULTS
A total of 11 case-control studies encompassing 2,609 cases and 8,171 controls on rs1012068 and three encompassing 411 cases and 1,448 controls on rs5998152 were included. Results indicated that the DEPDC5 rs1012068 polymorphism did not significantly increase HCC risk in the total population (allelic model (OR = 1.32, 95% CI = 1.04-1.67, = 0.02); the recessive model (OR = 1.42, 95% CI = 0.96-2.10, = 0.08); the dominant model (OR = 1.43, 95% CI = 1.09-1.87, = 0.01); the homozygous model (OR = 1.61, 95% CI = 1.01-2.57, = 0.05); the heterozygous model (OR = 1.39, 95% CI = 1.09-1.79, = 0.009)). Subgroup analyses based on ethnicity and etiology revealed that the rs1012068 polymorphism, under all five genetic models, was associated with increased HCC risk in Asians or in individuals with chronic HBV infection but not in individuals with chronic HCV infection. A significant association was also observed between rs5998152 and HCV-related HCC risk in Asians chronically infected with HCV under allelic, dominant, and heterozygous models.
CONCLUSION
Our study suggests that the DEPDC5 rs1012068 polymorphism increases HCC risk, especially in Asians with chronic HBV infection, while the rs5998152 polymorphism increases HCC risk in Asians with chronic HCV infection.

Meta-Analysis Review
BACKGROUND/AIMS
Pancreatic fluid collections (PFC) are debris or fluid of the pancreas that needs to be drained out. This may result from surgery or necrotizing pancreatitis. This meta-analysis compared the outcomes of PFC through endoscopic and percutaneous interventions.
METHODS
A medical database was searched up to June 2022, comparing the outcomes of endoscopic drainage (ED) and percutaneous drainage (PD) for the PFC. Eligible studies reporting clinical and technical success and adverse events were selected.
RESULTS
Seventeen studies with 1170 patients were included for meta-analysis, of which 543 patients underwent ED and 627 underwent PD. The odd ratio (OR) of technical success was 0.81 (95% confidence interval (CI) 0.31, 2.1) and clinical success was in the favor of the ED group at OR 2.23 (95% CI 1.45, 3.41). Adverse events OR 0.62 (95% CI 0.27, 1.39) and stent migration OR 0.61 (95% CI 0.10, 3.88) were the same in both groups, but hospital stay pooled mean difference of 15.02 days (95% CI 9.86, 20.18), mortality OR 0.24 (95% CI 0.09, 0.67), and re-interventions OR 0.25 (95% CI 0.16, 0.40) favored ED.
CONCLUSIONS
ED is safe and efficient for PFC with higher clinical success, lower mortality rate, hospital stay, and re-interventions compared with PD.

Meta-Analysis
BACKGROUND
Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy (PD) or pylorus-preserving pancreaticoduodenectomy (PPPD). However, its risk factors are still unclear. This meta-analysis aimed to identify the potential risk factors of DGE among patients undergoing PD or PPPD.
MATERIALS AND METHODS
We searched PubMed, EMBASE, Web of Science, Cochrane Library, Google Scholar, and ClinicalTrial.gov for studies that examined the clinical risk factors of DGE after PD or PPPD from inception through 31 July 2022. We pooled odds ratios (ORs) with 95% CIs using random-effects or fixed-effects models. We also performed heterogeneity, sensitivity, and publication bias analyses.
RESULTS
The study included a total of 31 research studies, which involved 9205 patients. The pooled analysis indicated that out of 16 nonsurgical-related risk factors, three risk factors were found to be associated with an increased incidence of DGE. These risk factors were older age (OR 1.37, P =0.005), preoperative biliary drainage (OR 1.34, P =0.006), and soft pancreas texture (OR 1.23, P =0.04). On the other hand, patients with dilated pancreatic duct (OR 0.59, P =0.005) had a decreased risk of DGE. Among 12 operation-related risk factors, more blood loss (OR 1.33, P =0.01), postoperative pancreatic fistula (POPF) (OR 2.09, P <0.001), intra-abdominal collection (OR 3.58, P =0.001), and intra-abdominal abscess (OR 3.06, P <0.0001) were more likely to cause DGE. However, our data also revealed 20 factors did not support stimulative factors influencing DGE.
CONCLUSION
Age, preoperative biliary drainage, pancreas texture, pancreatic duct size, blood loss, POPF, intra-abdominal collection, and intra-abdominal abscess are significantly associated with DGE. This meta-analysis may have utility in guiding clinical practice for improvements in screening patients with a high risk of DGE and selecting appropriate treatment measures.

Review
BACKGROUND
Cystic fibrosis (CF) is an autosomal recessive, life-limiting, multisystem disease affecting over 70,000 individuals worldwide. Between 80% and 90% of people with CF suffer with pancreatic exocrine insufficiency, which if left untreated, leads to a poor nutritional status. Pancreatic enzyme replacement therapy (PERT) has been shown to be effective in improving nutritional status and subsequently associated with improved lung function. However, the timings of PERT administration in relation to a meal are subjective and not standardised, meaning that variations in the timing of PERT dosing persist.
OBJECTIVES
The primary objective of the review is to compare the efficacy (fat absorption) and effectiveness (nutritional status, lung function and quality of life) of different PERT dosing strategies in terms of timing of administration for treating dietary malabsorption in all individuals with CF.
SEARCH METHODS
We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews. Date of last search: 24 June 2021. We also searched ongoing trials registers on 09 July 2021.
SELECTION CRITERIA
Randomised controlled trials (RCTs), including cross-over RCTs with a minimum washout period of two weeks, and quasi-RCTs of PERT dosing regimens in people (of any age) with CF.
DATA COLLECTION AND ANALYSIS
Two authors independently assessed and screened the studies identified from the searches. We planned to use GRADE to assess the certainty of evidence for our pre-specified critical outcomes, but we did not identify any eligible studies.
MAIN RESULTS
No studies met the eligibility criteria and therefore we did not include any in this review. The excluded studies were either cross-over in design (but lacking a sufficient washout period between treatments) or did not assess the timing of PERT. One study which was terminated early is awaiting assessment pending further information.
AUTHORS' CONCLUSIONS
We were unable to determine whether one dosing schedule for PERT is better than another since we identified no eligible RCTs. While the introduction of PERT to people with CF can improve their nutritional status, there are a limited number of studies which address this review question, and none met our eligibility criteria. Since malnutrition and adverse gastrointestinal symptoms remain a common feature in CF, the assessment of the relative performance of dosing schedules may provide evidence to improve outcomes in people with CF who are pancreatic insufficient. Further research is needed to fully evaluate the role of dosing schedules for PERT in fat absorption. Research should also establish reliable outcome measures and minimal clinically important differences. While RCTs with a cross-over design may have advantages over a parallel group design, an adequate washout period between intervention periods is essential.

Review
OBJECTIVE
This study aimed to determine the effect of prophylactic use of carbapenems for acute pancreatitis on clinical outcomes.
MATERIALS AND METHODS
It was conducted according to the preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by using the keywords "Pancrea AND carbapenem OR imipenem OR ertapenem OR meropenem OR doripenem." Primer outcomes were mortality, surgical intervention, and pancreatic and non-pancreatic infection. Subgroup analyses were also performed to reduce the risk of bias.
RESULTS
Ten studies with 4038 patients were included in the meta-analyses. While eight of ten were randomized controlled trials, two were observational studies. The prophylactic use of carbapenems had no statistically significant effect on mortality (OR=0.82, 95% CI=0.65-1.04, I²=0%) and surgical intervention. (OR=0.81, 95% CI=0.57-1.17, I²=0%). However, the real impact of prophylaxis on reducing the incidence of mortality and surgical intervention was uncertain due to the insufficient sample size. The prophylactic use of carbapenems was significantly associated with a lower risk of peripancreatic (OR=0.37, 95% CI=0.25-0.55, I²=61%) and non-pancreatic infection risk (OR=0.60, 95% CI=0.46-0.78, I²=65%). The definitions of infection in the articles were not clear, and the diagnostic approach to infection was based on subjective criteria. In addition, there was inadequate collateral damage and safety assessments. In high-quality studies with a low risk of bias, prophylactic carbapenems had no effect on peripancreatic infection (RR=1.54, 95% CI=0.65-3.47, I²=0%) and non-pancreatic infection (RR=0.72, 95% CI=0.48-1.07, I²=0%).
CONCLUSION
Although there is a reduction in the infection risk, routine carbapenem use in acute pancreatitis cases should not be recommended based on current evidence. Cooperation with Infectious Disease specialists and developing diagnostic algorithms are required instead of routine prophylaxis to prevent infection, especially non-pancreatic infection.
