Composition and functional profiles of gut microbiota reflect the treatment stage, severity, and etiology of acute pancreatitis. Microbiol Spectr 2023; 11:e0082923.

Abstract
Acute pancreatitis (AP) is a type of digestive system disease with high mortality. Previous studies have shown that gut microbiota can participate in developing and treating acute pancreatitis by affecting the host's metabolism. In this study, we followed 20 AP patients to generate longitudinal gut microbiota profiles and activity during disease (before treatment, on the third day of treatment, and 1 month after discharge). We analyzed species composition and metabolic pathways' changes across the treatment phase, severity, and etiology. The diversity of the gut microbiome of patients with AP did not show much variation with treatment. In contrast, the metabolic functions of the gut microbiota, such as the essential chemical reactions that produce energy and maintain life, were partially reinstated after treatment. The severe AP (SAP) patients contained less beneficial bacteria (i.e., Bacteroides xylanisolvens, Clostridium lavalense, and Roseburia inulinivorans) and weaker sugar degradation function than mild AP patients before treatment. Moreover, etiology was one of the drivers of gut microbiome composition and explained the 3.54% variation in species' relative abundance. The relative abundance of pathways related to lipid synthesis was higher in the gut of hyperlipidemia AP patients than in biliary AP patients. The composition and functional profiles of the gut microbiota reflect the severity and etiology of AP. Otherwise, we also identified bacterial species associated with SAP, i.e., Oscillibacter sp. 57_20, Parabacteroides johnsonii, Bacteroides stercoris, Methanobrevibacter smithii, Ruminococcus lactaris, Coprococcus comes, and Dorea formicigenerans, which have the potential to identify the SAP at an early stage. IMPORTANCE Acute pancreatitis (AP) is a type of digestive system disease with high mortality. Previous studies have shown that gut microbiota can participate in the development and treatment of acute pancreatitis by affecting the host's metabolism. However, fewer studies acquired metagenomic sequencing data to associate species to functions intuitively and performed longitudinal analysis to explore how gut microbiota influences the development of AP. We followed 20 AP patients to generate longitudinal gut microbiota profiles and activity during disease and studied the differences in intestinal flora under different severities and etiologies. We have two findings. First, the gut microbiota profile has the potential to identify the severity and etiology of AP at an early stage. Second, gut microbiota likely acts synergistically in the development of AP. This study provides a reference for characterizing the driver flora of severe AP to identify the severity of acute pancreatitis at an early stage.

Abstract
Introduction Multiple drug-resistant Gram-negative bacterial (MDR-GNB) bacteraemia poses a serious threat to patients in hospital. Infected pancreatic necrosis (IPN) patients are a vulnerable population to infectious complications during hospitalization. This study aims to evaluate the impact of MDR Gram-negative bacteraemia on IPN patients. Methods A case-control study was performed with data collected from 1 January 2016 to 1 July 2022 in a Chinese tertiary teaching hospital. Clinical data of the IPN patients with MDR-GNB bacteraemia were analyzed and compared to those of a matched control group without MDR-GNB bacteraemia (case-control ratio of 1:2). Comparisons were performed between with/without MDR-GNB bacteraemia and different severities of acute pancreatitis (AP). Independent predictors of overall mortality were identified via univariate and multivariate binary logistic regression analyses. Results MDR-GNB bacteraemia was related to a higher mortality rate (62.5% vs. 8.3%, p < 0.001). Severe AP combined with MDR-GNB bacteraemia further increased mortality up to 81.3% (p = 0.025). MDR-GNB bacteraemia (odds ratio (OR) = 8.976, 95% confidence interval (CI) = 1.805 -44.620, p = 0.007) and severe AP (OR = 9.414, 95% CI = 1.742 -50.873, p = 0.009) were independent predictors of overall mortality. MDR- Klebsiella pneumoniae was the most common causative pathogen. Conclusion A higher mortality rate in IPN patients was related to MDR-GNB bacteraemia and further increased in severe AP patients combined with MDR-GNB bacteraemia.

Abstract
Background There are few published reports describing the clinical characteristics of acute pancreatitis (AP) patients with multidrug-resistant organism (MDRO) infection. Methods This was a retrospective analysis of AP patients with MDRO infection in West China Hospital between July 2015 and June 2020. Basic clinical data, disease progression states, and prognoses of the MDRO and non-MDRO infection groups were compared and analyzed. Logistic regression analysis was performed to explore the related risk factors for MDRO infection. The prognoses of different MDRO infection types were compared. Results In total, 9812 AP patients were included, 2436 (24.83%) of whom had healthcare-associated infections (641 [26.31%] MDRO infections and 1795 [73.69%] non-MDRO infections). The main MDRO strain was carbapenem-resistant Acinetobacter baumannii (CRAB) (400/62.40%). The rate of discharge against doctor’s advice, mortality, hospitalization expenses, and hospitalization days was higher in the MDRO infection group than in the noninfection group. By logistic regression analysis, the independent risk factors associated with MDRO infection included male sex (OR 1.36, 95% CI 1.09~1.70), severity (OR 1.40, 95% CI 1.10~1.78), ICU referral (OR 2.48, 95% CI 1.79~3.44), abdominal puncture (OR 2.78, 95% CI 1.93~4.02), fiberoptic bronchoscopy (OR 1.95, CI 1.35~2.81), and PICC/CVC placement (OR 1.48, CI 1.06~2.06). Compared with biliary and hypertriglyceridemia (HTG) (OR 0.94, 95% CI 0.73~1.23), alcohol (OR 0.30, 95% CI 0.19~0.47) and other etiologies (OR 0.58, 95% CI 0.41~0.81) conferred a lower risk of MDRO infection. The carbapenem-resistant Klebsiella pneumoniae (CRKP) infection rate was highest in the patients who died. Conclusion The CRAB proportion was highest in AP patients with MDRO infection. MDRO infection is related to many factors, has a poor prognosis, and increases the patient burden. CRKP infection is directly related to poor prognosis.

Abstract
Background Infection in patients with acute pancreatitis, especially severe acute pancreatitis patients, is a common and important phenomenon, and the distributions and drug resistance profiles of bacteria causing biliary infection and related risk factors are dynamic. We conducted this study to explore the characteristics of and risk factors for bacterial infection in the biliary tract to understand antimicrobial susceptibility, promote the rational use of antibiotics, control multidrug-resistant bacterial infections and provide guidance for the treatment of acute pancreatitis caused by drug-resistant bacteria. Methods The distribution of 132 strains of biliary pathogenic bacteria in patients with acute pancreatitis from January 2016 to December 2020 were analyzed. We assessed drug resistance in the dominant Gram-negative bacteria and studied the drug resistance profiles of multidrug-resistant bacteria by classifying Enterobacteriaceae and nonfermentative bacteria. We then retrospectively analyzed the clinical data and risk factors associated with 72 strains of Gram-negative bacilli, which were divided into multidrug-resistant bacteria (50 cases) and non-multidrug-resistant bacteria (22 cases). Results The main bacteria were Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa. Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli had a 66.67% detection rate. Acinetobacter baumannii had more than 50.00% drug resistance to carbapenems, ESBL-producing Klebsiella pneumoniae had 100.00% drug resistance, and Pseudomonas aeruginosa had 66.67% resistance to carbapenems. Multivariate logistic regression analysis suggested that the administration of third- or fourth-generation cephalosporins was an independent risk factor for Gram-negative multidrug-resistant biliary bacterial infection in acute pancreatitis patients. Conclusion Drug resistance among biliary pathogens in acute pancreatitis patients remains high; therefore, rational antimicrobial drug use and control measures should be carried out considering associated risk factors to improve diagnosis and treatment quality in acute pancreatitis patients.

Abstract
Background Multidrug-resistant (MDR) Klebsiella pneumoniae infections, from pancreatic infections to bloodstream infections, influence the mortality of patients with acute pancreatitis (AP) on the condition of limited antibiotic choices. The aim of this study was to investigate the predictor of mortality among AP patients complicated with MDR-K. pneumoniae infections. Methods Seventy-one AP patients who occurred MDR-K. pneumoniae infections from August 1st, 2016 to August 1st, 2020 were enrolled. MDR-K. pneumoniae was defined as the K. pneumoniae strain non-susceptible to at least one agent in three or more antimicrobial categories. MDR-K. pneumoniae isolates were confirmed by Vitek-2 system. Antibiotic susceptibility test was carried out using a micro broth dilution method. Clinical characteristics and drug-resistance rates were retrospectively reviewed, and the predictors of mortality were evaluated by univariate and multivariate analyses. Results The mortality rate of AP patients complicated with MDR-K. pneumoniae infections reached 46.5% (33 of 71), and pancreas (n = 53) was the most common site of MDR-K pneumoniae strains. The drug resistance rates of MDR-K. pneumoniae were high to 11 of 12 common antibiotics (more than 50.0%) except of tigecycline (23.9%). The predictor independently associated with mortality was septic shock (hazard ratio 2.959, 95% confidence intervals 1.396 – 6.272, P = 0.005). Conclusions More attention should be paid for pancreatic MDR-K. pneumoniae infections among AP patients The predictor for mortality of AP patients complicated with MDR-K. pneumoniae infection is septic shock. Therefore, further clinical investigations should focus on areas against septic shock.

Abstract
Efflux pumps are one of the predominant microbial resistant mechanisms leading to the development of multidrug resistance. In Staphylococcus aureus, overexpression of NorA protein enables the efflux of antibiotics belonging to the class of fluoroquinolones and, thus, makes S. aureus resistant. Hence, NorA efflux pumps are being extensively exploited as the potential drug target to evade bacterial resistance and resensitize bacteria to the existing antibiotics. Although several molecules are reported to inhibit NorA efflux pump effectively, boronic acid derivatives were shown to have promising NorA efflux pump inhibition. In this regard, the current study exploits 6-(3-phenylpropoxy)pyridine-3-boronic acid to further improve the activity and reduce cytotoxicity using the bioisostere approach, a classical medicinal chemistry concept. Using the SWISS-Bioisostere online tool, from the parent compound, 42 compounds were obtained upon the replacement of the boronic acid. The 42 compounds were docked with modeled NorA protein, and key molecular interactions of the prominent compounds were assessed. The top hit compounds were further analyzed for their drug-like properties using ADMET studies. The identified potent lead, 5-nitro-2-(3-phenylpropoxy)pyridine (5-NPPP), was synthesized, and in vitro efficacy studies have been proven to show enhanced efflux inhibition, thus acting as a potent antibiotic breaker to resensitize S. aureus without elucidating any cytotoxic effect to the host Hep-G2 cell lines.

Abstract
Background Infection is one of the important causes of death in patients with severe acute pancreatitis (SAP), but the bacterial spectrum and antibiotic resistance are constantly changing. Making good use of antibiotics and controlling multi-drug-resistant (MDR) bacterial infections are of vital importance in improving the cure rate of SAP. We conducted a retrospective study in the hope of providing references for antibiotic selection and control of drug-resistant bacteria. Methods Retrospective analysis was performed on the data of patients hospitalized in our hospital due to acute pancreatitis (AP) in the past 5 years. General data were classified and statistically analyzed. Subsequently, the bacterial spectrum characteristics and the data related to drug-resistant bacterial infection of 569 AP patients were analyzed. Finally, unconditional logistic regression analysis was conducted to analyze the risk factors of MDR infection. Results A total of 398 patients were enrolled in this study and the hospitalization data and associated results were analyzed. A total of 461 strains of pathogenic bacteria were detected, including 223 (48.4%) gram-negative bacterial strains, 190 (41.2%) gram-positive bacterial strains and 48 (10.4%) fungal strains. The detection rates of resistance in gram-negative and gram-positive bacterial strains were 48.0% (107/223) and 25.3% (48/190), respectively. There were significant differences between the MDR group and the non-MDR group for the factors of precautionary antibiotic use, kinds of antibiotics used, receipt of carbapenem, tracheal intubation, hemofiltration and number of hospitalization days in the intensive care unit. Unconditional logistic regression revealed 2 risk factors for MDR bacterial infection. Conclusions Our results illustrate that gram-negative bacteria were the most common pathogens in SAP infection, and the proportion of gram-positive bacteria increased notably. The rate of antibiotic resistance was higher than previously reported. Unconditional logistic regression analysis showed that using more types of antibiotics and the number of hospitalization days in the ICU were the risk factors associated with MDR bacterial infection.

Abstract
BACKGROUND Multidrug-resistant organisms (MDROs) is becoming a serious worldwide threat to public health. However, the impact of MDROs on the outcomes of the patients with infected pancreatic necrosis (IPN) remains unclear. This study aims to evaluate the roles of MDROs in IPN. METHODS A prospectively maintained database of 188 patients with IPN between January 2010 and May 2019 was analyzed. The microbiology profile of organisms isolated from wall-off necrosis (WON) was specifically investigated to correlate with the outcomes of the patients. RESULTS Of the 188 patients with IPN, 108 patients (57.4%) had MDROs detected in aspirates from WON. Carbapenem-resistant Klebsiella pneumoniae (CRKP) accounted for 43.5% of the MDROs isolated (60/138), followed by Carbapenem-resistant Acinetobacter baumanii (CRAB) (34.8%, 48/138) and Escherichia coli producing an extended-spectrum beta-lactamase (ESBLp) (6.5%, 9/138). MDROs infection was associated with higher mortality (35.2% vs 11.3%, P < 0.001), higher rate of hemorrhage (36.1% vs 11.3%, P < 0.001), longer intensive care unit (ICU) stay (23 vs 12 days, P < 0.001), longer hospital stay (68 vs 51 days, P = 0.001) and more hospitalization expenses (45,190 ± 31,680 vs 26,965 ± 17,167 $, P < 0.001). Multivariate analysis of predictors of mortality indicated that MDROs infection (OR = 2.6; 95% confidence interval [CI], 1.0-6.5; P = 0.042), age ≥ 50 years (OR = 2.6; 95% CI, 1.2-5.8; P = 0.016), severe category (OR = 2.9; 95% CI, 1.1-8.0; P = 0.035), bloodstream infection (OR = 3.4; 95% CI, 1.5-7.6; P = 0.049), step-down surgical approach (OR = 2.7; 95% CI, 1.1-6.2; P = 0.023) were significant factors. CONCLUSIONS MDROs infection was prevalent among patients with IPN and associated with adverse clinical outcomes and increased mortality.

Abstract
We report a case of a 35-year-old male with a pancreatic pseudocyst, who developed bilateral endogenous endophthalmitis, 4 days after surgical drainage of the pseudocyst. Bacterial cultures of the pancreatic drain fluid and the vitreous tap showed the growth of Klebsiella pneumoniae. The cultured organism was resistant to all the tested antibiotics except colistin. Intravenous colistin was instituted and three injections of intravitreal colistin were given in the left eye of the patient. Complete resolution of infection was seen and visual acuity of 6/6 was regained in both eyes, which was maintained at 4-month follow-up.

Abstract
The aim of the present study was to investigate the phenotype and genotype of plasmid-mediated AmpC (pAmpC) β-lactamase in Klebsiella pneumoniae and its antibiotic resistance. A total of 130 non-repetitive clinical isolates of Klebsiella pneumoniae, obtained from tertiary hospitals, were phenotypically screened for pAmpC β-lactamase production with the cefoxitin disk diffusion test. β-lactamase genes in the screened isolates were detected using multiplex polymerase chain reaction (PCR); carbapenemase genes in pAmpC β-lactamase-producing isolates that were resistant to imipenem were detected using PCR. Out of the 130 isolates of Klebsiella pneumoniae, 62 strains (47.7%) were resistant to cefoxitin, including 14 strains (10.8%) positive for pAmpC β-lactamase (DHA type), among which 12 strains (85.7%) were susceptible to imipenem, and 2 strains, which were carrying Klebsiella pneumoniae carbapenemase (KPC)-2 gene, were resistant to imipenem. The pAmpC β-lactamase-producing Klebsiella pneumoniae isolates from the tertiary hospitals were mainly of DHA-1 genotype, and the majority were susceptible to carbapenems; drug-resistant strains were associated with KPC-2 expression.

Enterococcus hirae Bacteremia Associated with Acute Pancreatitis and Septic Shock. Case Rep Infect Dis 2015; 2015:123852.

Abstract
Infection with Enterococcus hirae has rarely been reported in humans but is not uncommon in mammals and birds. We describe a case of Enterococcus hirae bacteremia associated with acute pancreatitis, acute cholecystitis, and septic shock responsive to antibiotic therapy and supportive critical care management. Unique aspects of this case of Enterococcus hirae bacteremia are its association with acute pancreatitis and its geographical origin. To our knowledge, this is the first report of Enterococcus hirae bacteremia occurring in a patient in the United States. Although human infection with this organism appears to be rare, all cases reported to date describe bacteremia associated with severe and life-threatening illness. Thus, physicians need to be cognizant of the clinical significance of this heretofore little recognized pathogen.
