Abstract
BACKGROUND Collection of bile aspirate during endoscopic retrograde cholangiopancreatography (ERCP) is essential to identify pathogens responsible for acute cholangitis. Limited data are available on the risk factors for the presence of multidrug-resistant organisms (MDRO) in bile. METHODS We conducted this retrospective, single-center study to assess the prevalence and susceptibility rates of bacteria in bile cultures, and the risk factors for the presence of pathogens, MDRO, and fungi in bile. All consecutive patients who underwent biliary drainage for acute cholangitis from January 2017 to December 2019 were included. RESULTS 443/1610 ERCPs were performed for acute cholangitis. Bile culture was collected in 91.4% (405/443), of which 86.7% were positive. Most common isolates were Enterococcus faecalis (37.6%) and Escherichia coli (32.8%). Vancomycin resistance was found in 9.9% of Enterococcus species (spp.); extended-spectrum beta-lactamases (ESBL) and carbapenemases in 11.2% and 0.9% of Enterobacteriaceae, respectively. The empiric antimicrobial therapy was changed in 26.4% (n = 107) of cases, with a clinical response in 90.7%. In multivariate analysis, biliary stenting was an independent risk factor for positive bile culture (odds ratio [OR] 9.43; P < 0.01). Independent risk factors for MDRO in bile were patient age>60 years (OR 2.51; P = 0.03), previous sphincterotomy (OR 2.57; P = 0.02), and biliary stenting (OR 2.80; P < 0.01). Previous sphincterotomy was the only risk factor for isolation of fungi in bile (OR 1.61; P = 0.04). CONCLUSIONS Our study showed an increasing prevalence of Enterococcus spp. and MDRO. Bile cultures should be routinely collected in cholangitis and in patients with repeated ERCPs to allow more efficient antimicrobial treatment.

Abstract
Introduction Bile is deemed a sterile fluid, with the presence of clinical conditions like cholelithiasis, cholecystitis, previous biliary interventions, biliary strictures, and so on, leading to bile stasis, and increases the chances of bacteriobilia. In this study, we recognize the bacterial spectrum of microorganisms isolated from bile samples, diagnostic parameters, and antibiotic sensitivity patterns. Methods A retrospective observational study was carried out by compiling data from the hospital information system of a tertiary care center from 2021 to 2022 to evaluate biliary infections in patients who underwent surgical procedures related to the biliary tract and associated organs. Results A total of 234 patients' bile samples were included in our study. The mean age of patients was 48.04 ± 14.74 years, with more patients below the age of 65 years among those with infected bile samples. One hundred and sixty-three (163/234, 69.66%) patients infected by 209 pathogenic microorganisms were recognized. The most common microorganism isolated was Escherichia coli (83/209, 39.71%), followed by Pseudomonas aeruginosa (37/209, 17.7%). Acinetobacter baumannii and Klebsiella pneumoniae isolate owed to more than 90% penicillin, extended-spectrum beta-lactamase, carbapenem, and fluoroquinolone resistance among all isolates. Length of hospital stay, malignant obstruction, and chronic kidney disease were identified as statistically significant risk factors that lead to the isolation of multi-drug-resistant isolates from bile culture. Conclusion We recognized the spectrum of pathogens causing biliary tract infections at our center along with the antibiotic resistance pattern to guide and facilitate prompt and appropriate treatment by primary health care professionals and family medicine practitioners.

Abstract
Background and Aim Biliary obstruction causes bacteriobilia and significant morbidity and high mortality, which necessitates prompt and effective treatment for a good clinical outcome. Hence, the aim of this study was to determine updated knowledge of biliary microbial spectrum, antibiotic sensitivity pattern, and key clinical factors of bacteriobilia. Methods This is a prospective study conducted during the period between November 2021 and December 2022 at Ibn Sina specialized hospital, Khartoum, Sudan, on 50 patients diagnosed with obstructive jaundice and symptomatic bacteriobilia who underwent open biliary surgeries electively. Bile samples were aspirated intra-operatively and cultured, and antibiotic sensitivity tests were performed. Results Fifty-four percent of patients diagnosed with obstructive jaundice who underwent elective open biliary surgeries were males with the ratio (2:1). Forty-six percent of patients were between 61 and 75 years (elderly). The most frequent cause of obstructive jaundice was migrating biliary stones (48% of cases). Thirty-two percent of patients were diabetic with bacteriobilia. The predominant isolated bacterial pathogen in this study was Escherichia coli (36% of cases). These biliary pathogens were sensitive to meropenem in 54% of cases and ciprofloxacin in 46%. Eventually, in all patients in this study, biliary bacterial pathogens were found to be resistant to a broad spectrum of antibiotics. Conclusion Careful selection of empirical antibiotic therapy based on surveillance of routine bile cultures during biliary tree procedures in patients with high risk of bacteriobilia will potentially help in improving the surgical outcomes and optimizing treatment of acute cholangitis, which is associated with high mortality.

Abstract
Background Blockage of the biliary tract is commonly caused by malignant tumors leading to deranged liver function, responsible for poor prognosis and a high rate of bacteriobilia leading to mortality. Material and methods We collected retrospective data from the hospital information system and laboratory registers in our department from 2021 to 2022 to evaluate biliary infections in patients with hepato-pancreatico-biliary and associated intraabdominal malignancies. Result A total of 118 (118/234, 50.43%) patients' bile samples were estimated in this study. Patients' average age was 53.02 ± 13.49 years, with more patients below the age of 65 years among those with infected bile samples. Eight patients were infected by 102 pathogenic microorganisms. The most common pathogenic microorganism responsible for biliary infection in patients with abdominal malignancies was Escherichia coli (38/102, 37.25%) followed by Klebsiella pneumoniae (21/102, 20.59%) and Enterococcus spp. (18/102, 17.65%). Underlying comorbidities like diabetes mellitus, hypothyroidism, hypoproteinemia, chronic liver disease, immunosuppression, chronic kidney disease, increased hospital stay, admission to the intensive care unit (ICU), and presence of percutaneous transhepatic biliary drain were statistically significant risk factors for isolation of multidrug-resistant pathogenic bacteria. Conclusion Our study guided physicians in identifying the associated demographic characteristics, risk factors, and the spectrum of pathogens responsible for bacteriobilia in abdominal cancer patients along with the antibiotic resistance pattern among these isolates and better selection of antibiotics and antibiotic prophylaxis for patients at risk of developing biliary tract infections with multidrug-resistant pathogens.

Implications of Type 2 Diabetes Mellitus in Patients with Acute Cholangitis: A Systematic Review of Current Literature. Healthcare (Basel) 2022; 10:healthcare10112196. [PMID: 36360537 PMCID: PMC9691116 DOI: 10.3390/healthcare10112196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 10/25/2022] [Accepted: 10/31/2022] [Indexed: 11/06/2022] Open
Abstract
Introduction: Type 2 diabetes mellitus (T2DM) has been associated with higher rates and poorer prognosis of infections, mainly due to poor glycemic control, reduced response of T-cells and neutrophils, and impaired migration, phagocytosis, and chemotaxis of leukocytes. However, the impact of T2DM on acute cholangitis (AC) has not been assessed so far. Thus, we aimed to explore this association by means of a systematic review of the literature. Methods: This systematic review was carried out based on the recommendations stated in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched the PubMed/MEDLINE, Web of Science and SCOPUS databases to identify relevant publications depicting an association between T2DM and AC from the inception of these search services up to present. Results: We detected a total of 435 eligible records. After we applied the inclusion and exclusion criteria, a total of 14 articles were included in the present systematic review. Included manuscripts focused on the potential role of T2DM as a risk factor for the development of AC and on its contribution to a worse prognosis in AC, e.g., development of sepsis or other complications, the risk of AC recurrence and the impact on mortality. Conclusions: As compared to non-diabetic individuals, patients with T2DM have a higher risk of AC as a complication of choledocholithiasis or gallstone pancreatitis. Several oral hypoglycemic drugs used in the management of T2DM may also be involved in the onset of AC. Diabetic patients who suffer from AC have a higher likelihood of longer hospital stays and sepsis, as well as a higher risk of mortality and more severe forms of AC as compared to non-diabetic individuals.

Abstract
Aim This study aimed to provide profiles of microorganisms isolated from bile and antibiotic susceptibility patterns of biliary tract infections (BTIs) in our center. Methods A total of 277 patients diagnosed with BTIs at the Second Affiliated Hospital of Harbin Medical University from 2011 to 2018 were included in this study. Medical records were reviewed to obtain clinical and demographic data. Bile specimens were prepared through endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiodrainage (PTCD), and percutaneous transhepatic gallbladder drainage (PTGD) under aseptic conditions. In those with positive bile culture results, blood cultures were concurrently conducted. The concordance of the results between bile culture and blood culture were also analysed. Results Two hundred and sixty-seven bile cultures were positive, while 280 strains of micro-organisms were isolated. Among these, 76.8% were Gram-negative, 22.5% were Gram-positive and 0.7% were fungi. The most common microorganisms were Escherichia coli, Klebsiella pneumoniae, and Enterococcus faecalis. Gram-negative bacteria we tested were highly sensitive to ertapenem, imipenem, tigecycline, and amikacin. Gram-positive bacteria we tested were highly sensitive to tigecycline, teicoplanin, linezolid, vancomycin, and chloramphenicol. For the 44 patients with positive bile cultures, a blood culture was also performed. Among them, 29 cases yielded positive blood culture results. Among those cases with positive blood culture, 48.3% showed complete agreement with bile culture, 3.4% showed partial agreement, and 48.3% showed disagreement. The most common microorganisms in blood culture were the same as in bile culture. Additionally, the proportion of Staphylococcus epidermidis was significantly higher in blood culture (P < 0.05). Conclusion Our study provided a comprehensive analysis of the bacteria distribution and drug resistance profiles in patients with BTIs in northern China. Further studies should be conducted to validate our findings.

Abstract
Background To investigate the difference in the severity of illness, organ dysfunction, and prognosis of acute cholangitis due to different pathogenic bacterial infection types. Methods A retrospective observational study was performed. Patients who met the selection criteria according to blood culture and bile culture results of different pathogenic bacterial were divided into groups. The severity of illness, organ dysfunction, and prognosis of the groups were analyzed and compared comprehensively. Results A total of 424 patients were included, and no bacterial growth developed in 111 patients (26.2%). Among the 313 patients (73.8%) with bacterial growth, 155 patients had only Gram-negative bacteria cultured (49.5%), 48 patients had only Gram-positive bacteria cultured (15.3%), and 110 patients had both Gram-negative and Gram-positive bacteria cultured (35.1%). The proportion of Grade III patients and the APACHE II and SOFA scores of the mixed Gram-negative and positive group were the highest (p < 0.05); the intensive care unit admission day and hospital stay were longer, and the mortality rate were also higher 20/110 (18.2%) than the other two groups. Regression analysis showed that bacterial growth was an independent risk factor for organ dysfunction. The risks of an increased septic shock, neurological dysfunction, hepatic dysfunction, hematological dysfunction, and respiratory dysfunction in the mixed Gram-negative and positive group were higher than the Gram-negative group (P < 0.05). The Cox proportional hazards regression prompt showed that different culture results were independent risk factors for death. The mixed Gram-negative and positive group had increased hazard ratios and 95% CI of 7.30 (95% CI 1.55 to 34.38) compared with the Gram-negative group. There was no difference between the Gram-negative group and the Gram-positive group in the severity of illness, organ dysfunction, intensive care unit admission day, hospital stay, mortality rate, and risk of death (P > 0.05). Conclusions In acute cholangitis, mixed infection with Gram-negative and Gram-positive bacteria was more severe and was associated with a higher risk of death. There were no apparent differences between Gram-negative and Gram-positive bacterial infections.

Abstract
Ascending cholangitis and pyogenic liver abscesses are acute febrile bacterial hepatobiliary diseases. Nowadays they frequently occur in patients with structural changes of the biliary system and are usually treated by a combination of interventional drainage procedures and antimicrobial therapy. While Gram-negative Enterobacterales were identified as major causes in the past, biliary tract interventions and antibiotic exposure have contributed to an increase in enterococcal species and extended spectrum beta-lactamase (ESBL)-producing Enterobacterales. When selecting an appropriate empirical treatment the treating internist must consider local and individual risk factors for antimicrobial resistance in addition to pharmacokinetic aspects and disease severity to reduce the likelihood of treatment failure.

Abstract
Objective To study the distribution and risk factors of multidrug-resistant bacteria (MDROS) infection in orthopedic patients and to provide reference for clinical prevention and control measures. Methods The data of 239 inpatients with orthopedic trauma from June 2019 to December 2020 were selected as the research objects, and the distribution characteristics of MDROS infection were analyzed through the real-time monitoring system of nosocomial infection. Logistic regression analysis was used to screen out the risk factors causing MDROS infection, and the preventive measures were put forward. Results 178 strains of pathogens were isolated from 239 patients, including 53 strains of MDROS, and the detection rate was 29.78%. The main pathogenic bacteria were ESBLs, MRSA, CRAB, CRE, and MDR/PDRPA. The main infection sites of MDROS in orthopedic patients were the respiratory tract and wound. No CRE1 was detected, and 64.39%, 17.42%, and 14.39% of ESBL-producing bacteria, MRSA, and MDR/PDRPA, respectively, were detected. Logistic multivariate analysis showed that the length of hospital stay, antibiotic use time, open injury, and serum albumin level were independent risk factors of MDROS infection in orthopedic trauma patients. Conclusion To prevent MDROS infection in orthopedic patients, we should start from many aspects, focusing on reducing unnecessary hospitalization days, rationally preventing the use of antibacterial drugs, effectively treating basic diseases, etc., timely and effective thorough debridement, strengthening functional training, reducing bed rest, and strengthening targeted monitoring of related infections which are the keys to reduce MDROS infection in orthopedic patients.

Abstract
Background Biliary infections like cholecystitis and cholangitis are common and could be life threatening if treated inappropriate. Prescribing antibiotics is the key to control such infections. Occurrence of bacterial resistance to antibiotics is highly probable and should be continuously monitored. This study aimed to re-evaluate bacterial species distribution and their interaction to antibiotics in biliary infections. Method Total 2288 patients who were diagnosed as whether acute or chronic cholecystitis with/without concurrent cholangitis enrolled in this cohort study. All were candidate for cholecystectomy operation. In the theatre a sterile bile sample was aspirated from the gallbladder as early as the organ was exposed. Analysis was performed on culture and antibiogram results. Results Finally 492 (21.5%) microorganism growth was seen in all culture environments. Bacterial colonization was most common in cholangitis (63.8%) which followed by acute (26%) and chronic (10.9%) cholecystitis respectively (p = 0.001). Escherichia coli (58%) and Klebsiella species (12.2%) were mostly isolated pathogens. Antibiogram study illustrated bacterial sensitivity of gram-negative pathogens to imipenem (100%), amikacin (98.1%), and gentamicin (90.4%) which in gram-positive bacterial species was 100% to imipenem, vancomycin, rifampcin, and clindamycin. Conclusion Cephalosporins as an empirical treatment for biliary infections is not suitable. Aminoglycosides including amikacin and gentamycin are costly beneficial as the first line for empirical antibiotic therapy in selected patients because of their good bacterial sensitivity and low expenses. Imipenem should remain for multidrug resistance species. Distribution of bacterial species in biliary infection has not obviously changed in recent decades. Relative resistance of biliary germ to current advised antibiotic is flashed. Aminoglycoside more widely covers biliary germ than cephalosporin does in selected patient. Revision of current antibiotic guide for biliary infection to prevent antibiotic resistance is needed.

Abstract
Acute cholangitis, also referred to as ascending cholangitis, is an infection of the biliary tree characterized by fever, jaundice, and abdominal pain, which in most cases is the consequence of biliary obstruction. Diagnosis is commonly made by the presence of clinical features, laboratory tests, and imaging studies. The treatment modalities include administration of intravenous fluids, antimicrobial therapy, and prompt drainage of the bile duct. Early diagnosis and treatment of acute cholangitis are crucial to prevent unwanted clinical outcome of the disease. This article provides an update on early diagnosis and management of acute cholangitis.
