INTRODUCTION: Acute pancreatitis (AP) accounts for a high proportion of digestive diseases worldwide and has a high risk of infection. Pseudomonas aeruginosa, a common pathogen of hospital infections, has been observed to increase the resistance rate to several antibiotics, causing difficulties in treatments. Our study aims to investigate the impact of the multi-drug resistant Pseudomonas aeruginosa (MDR-PA) infections on AP patients. METHODS: At two Chinese tertiary referral centers for AP patients infected with MDR-PA, a retrospective case-control study with a 1:2 case-control ratio was performed...

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESSs) syndrome is an idiosyncratic drug-induced reaction that rarely occurs in children but can lead to serious complications. It manifests most commonly with fever, extensive skin eruptions, and eosinophilia. Symptoms typically develop two to six weeks after the initiation of the inciting drug. Visceral organ involvement especially the liver can also occur and if not recognized early and the inciting drug is not stopped immediately, it can lead to liver failure...

Klebsiella pneumoniae is an opportunistic pathogen associated with biofilm-based infections, which are intrinsically antibiotic resistant. Extracellular DNA plays a crucial role in biofilm formation and self-defence, with nucleases being proposed as promising agents for biofilm disruption. This study evaluated the in vitro and in vivo efficacy of DNase I in improving the activity of cefotaxime, amikacin and ciprofloxacin against K. pneumoniae biofilms. K. pneumoniae ATCC 700603 and a clinical isolate from catheter-related bloodstream infection were cultured for biofilm formation on microtiter plates, and the anti-biofilm activity of the antibiotics (0...

INTRODUCTION: Infections caused by carbapenemase-producing Enterobacteriaceae (CPE) are dramatically increasing worldwide, with an important impact on surgical patients. Our aim was to assess the clinical profile, outcomes, treatment, mortality and costs of CPE-related surgical site infection (SSI) in patients with abdominal surgery. METHODS: Review of CPE-related SSI in patients with abdominal surgery from January 2013 to December 2018. Patient factors and interventions present previously to the SSI identification were recorded, and a mortality analysis was also performed in patients with abdominal surgery and CPE-related organ/space SSI...

BACKGROUND: The aim was to evaluate the value of organ-specific weighted incidence antibiogram (OSWIA) percentages for bacterial susceptibilities of Gram-negative bacteria (GNB) collected from intra-abdominal infections (IAIs) during SMART 2010-2014. METHODS: We retrospectively calculated the OSWIA percentages that would have been adequately covered by 12 common antimicrobials based on the bacterial compositions found in the appendix, peritoneum, colon, liver, gall bladder and pancreas...

PRESENTATION: Patient is a 6-year-old male with CF, MRSA colonization, and pancreatic insufficiency that presented with worsening ppFEV1 and systemic symptoms despite multiple interventions. BAL grew NTM, Stenotrophomonas maltophilia, and Inquilinus limosus, a rare organism found in patients with CF. COURSE: I. limosus treatment was deferred. Despite treatment of other pathogens, symptoms worsened. I. limosus was targeted with meropenem, amikacin, and ciprofloxacin along with clindamycin for MRSA colonization...

The morphology and the drug sensitivity of the strain GYX2014-1 isolated from the hepatic pancreatic tissue of moribund Litopenaeus vannamei were evaluated by conventional culture characteristics, physical and chemical characteristics, and molecular biology methods. Detection of extracellulase and hemolysin activity shows that the isolated GYX2014-1 has protease, lipase, gelatinase activity, but none of amylase, or lecithinase activity. The 16S rRNA gene (GenBank accession number: KT781675) was analyzed, and a phylogenetic tree analysis showed that the isolated pathogen was most closely related to V...

BACKGROUND: Pseudomonas aeruginosa (P. aeruginosa) is a leading cause of nosocomial infections, which is difficult to treat because of limited susceptibility to antimicrobial agents. In China, isolation rates of P. aeruginosa were observed to increase by year. The incidence of infectious complications after pancreatoduodenectomy (PD) were high. However, there was no data available regarding P. aeruginosa infection in patients undergoing PD. This study evaluated the risk factors and clinical impacts of P...

BACKGROUND: The aim of the present study was to assess the influence of antibiotic therapy on fat assimilation in cystic fibrosis (CF) patients with small intestine bacterial overgrowth (SIBO). MATERIALS AND METHODS: Twenty six pancreatic insufficient CF patients with bronchopulmonary exacerbation and diagnosed SIBO (positive hydrogen-methane breath test) entered the study. (13)C mixed triglyceride breath test was performed before and after antibiotic therapy. Sixteen subjects were treated intravenously (ceftazidime and amikacin), ten patients orally (ciprofloxacin)...

Antibiotic therapy in the cystic fibrosis (CF) mouse model has been shown to result in reduced bacterial load of the intestine and significant body mass gain. The effect was suggested to be linked to the improvement of intestinal digestion and absorption. Therefore, we aimed to assess the influence of routinely applied antibiotic therapy in CF patients on fat assimilation. Twenty-four CF patients aged 6 to 30 years entered the study. Inclusion criteria comprised confirmed exocrine pancreatic insufficiency and bronchopulmonary exacerbation demanding antibiotic therapy...

There are a number of potential drugs for the treatment of cystic fibrosis (CF) currently undergoing clinical studies. A number of antibacterials formulated for delivery by inhalation are at various stages of study; these include dry-powder inhaler versions of colistin, tobramycin and ciprofloxacin, and formulations of azteonam, amikacin, levofloxacin, ciprofloxacin and fosfomycin/tobramycin for nebulization. Clinical trials of anti-inflammatory agents, including glutathione, phosphodiesterase-5 inhibitors such as sildenafil, oral acetylcysteine, simvastatin, methotrexate, docosahexaenoic acid, hydroxychloroquine, pioglitazone and alpha1-antitrypsin, are ongoing...

We describe a mediastinal pancreatic pseudocyst treated with a catheter drainage placed under computed tomographic guidance using a newly applied approach. A needle was angled cephalad with the computed tomographic gantry tilt technique, and was inserted into the lowest portion of the cavity through the liver and through the diaphragm. The needle pathway was necessitated by the location of the pseudocyst cavity. The drainage alleviated completely the symptoms with no complications. The puncture technique should be an option for accessing mediastinal lesions percutaneously...

Endoglucanase A from Clostridium thermocellum resistant to pancreatic proteinase was selected out of a range of microbial cellulases expressed in lactobacilli. Two Lactobacillus-E. coli expression vectors, harboring the endoglucanase gene from C. thermocellum under the control of its own promoter (pSD1) and the Lactococcus lactis lac A promoter (pSD2), were constructed separately. Intestinal Lactobacillus strains, L. gasseri and L. johnsonii, were electrotransformed with pSD1 and pSD2, and the stability of each plasmid was evaluated...

Edwardsiella tarda (E. tarda) has recently become recognized as a pathogen in humans. Here we report a new case of E. tarda bacteraemia complicated by acute pancreatitis and pyomyoma. A 46-year-old female came to our emergency room complaining of sudden onset of left upper quadrant pain and vomiting for the previous few hours after drinking three bottles of wine. An abdominal computed tomography (CT) scan revealed multiple biliary stones, acute pancreatitis with extensive inflammatory change, and a large uterine myoma...

Death from acute severe pancreatitis results from infection and multiple organ system failure occurring late in the course of illness. Patients with necrotizing pancreatitis involving at least one-third of the organ are at highest risk of secondary infection and death. We conducted a MEDLINE search to identify human trials of prophylactic antibiotics in acute pancreatitis. Results of early studies of prophylactic ampicillin to avoid secondary infection and death were negative, but the studies included patients with mild disease who are at low risk for infection...

BACKGROUND: Penetration of antibiotics into the pancreas is considered to be an important criterion in determining the most appropriate antibiotic treatment during severe acute pancreatitis. Our study investigated pancreatic penetration of five antibiotics in rats with and without acute necrotizing pancreatitis (ANP) (non-pancreatitis rats (NR), pancreatitis rats (AP)). METHODS: ANP was induced by intraductal bile acid injection, and 3 h later the antibiotic was administered...

A class of angiogenesis inhibitor has emerged from our mechanistic study of the action of angiogenin, a potent angiogenic factor. Neomycin, an aminoglycoside antibiotic, inhibits nuclear translocation of human angiogenin in human endothelial cells, an essential step for angiogenin-induced angiogenesis. The phospholipase C-inhibiting activity of neomycin appears to be involved, because U-73122, another phospholipase C inhibitor, has a similar effect. In contrast, genistein, oxophenylarsine, and staurosporine, inhibitors of tyrosine kinase, phosphotyrosine phosphatase, and protein kinase C, respectively, do not inhibit nuclear translocation of angiogenin...

Postantibiotic effects were induced in three Pseudomonas aeruginosa strains after short-term treatment (30 min) with amikacin at suprainhibitory concentrations in the range of 0.6-1.2 h (2 x MIC) and of 3.0-4.4 h (4 x MIC). Significant suppression of P. aeruginosa elastase activity was found after treatment with amikacin at 4 x MIC concentration (to 10-69.2% of the control values); 2 x MIC was less effective. The profile of outer membrane proteins of P. aeruginosa was not changed after treatment with amikacin at both concentrations...

Infectious complications currently account for 80% of deaths from acute pancreatitis. The aim of this study was to evaluate the necessity for prophylactic antibiotics in patients with severe acute pancreatitis. Twenty-three consecutive patients suffering from acute alcoholic pancreatitis with computed tomography demonstrating two or more fluid collections were randomly assigned to one of two groups receiving either nonantibiotic treatment or prophylactic antibiotics (ceftazidime, amikacine, and metronidazole for 10 days)...

The aim of the study was to verify whether antibiotics excreted by the normal pancreas are also excreted in human necrotizing pancreatitis, reaching the tissue sites of the infection. Twelve patients suffering from acute necrotizing pancreatitis were treated with imipenem-cilastatin (0.5 g), mezlocillin (2 g), gentamicin (0.08 g), amikacin (0.5 g), pefloxacin (0.4 g), and metronidazole (0.5 g). Serum and necrotic samples were collected simultaneously at different time intervals after parenteral drug administration by computed tomography-guided needle aspiration, intraoperatively, and from surgical drainages placed during surgery...
