Peritonitis is still the main infectious complication among patients on peritoneal dialysis. For treatment of peritoneal dialysis-related peritonitis, the intraperitoneal administration of antibiotics admixed to peritoneal dialysis fluids (PDFs) should be preferred. However, the influence of diverse PDFs on the activity of frequently used antibiotics has been investigated insufficiently. Thus, the present study set out to investigate the in vitro activity of fosfomycin against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus epidermidis, and Staphylococcus aureus in commercially available PDFs...

We report the clinical case of 23-year-old patient with liver cirrhosis of unknown genesis, significant resistant ascites, and 2 episodes of bleeding from esophageal varices. Evaluation did not find any cause of liver disease, and the patient was placed on the transplant wait list due to subcompensated liver function (Model for End-Stage Liver Disease score of 16, Child-Pugh class B) and poorly controlled severe portal hypertension. After treatment with diuretics, largevolume paracentesis, antibiotics, and vasoconstrictors, hepatorenal syndrome and spontaneous bacterial peritonitis resolved and liver function improved significantly...

Spontaneous bacterial (SBP) and spontaneous fungal peritonitis (SFP) can be a life-threatening infection in patients with liver cirrhosis (LC) and ascites. One of the possible mechanisms of developing SBP is bacterial translocation. Although the number of polymorphonuclear cells in the culture of ascitic fluid is diagnostic for SBP, secondary bacterial peritonitis is necessary to exclude. The severity of underlying liver dysfunction is predictive of developing SBP; moreover, renal impairment and infections caused by multidrug-resistant (MDR) organism are associated with a fatal prognosis of SBP...

The magur catfish (Clarias magur) is a facultative air-breather and regularly encounters with various environmental changes along with exposure to various bacterial pathogens in its natural habitats. Occurrence of various biochemical adaptational strategies related to nitrogen metabolism in magur catfish is already known. The present investigation aimed at determining the possible induction of inducible nitric oxide synthase (inos) gene and stimulation of nitric oxide (NO) production in this catfish while challenging with lipopolysaccharide (LPS, a bacterial endotoxin) treatment, and also to determine the involvement of nuclear factor kappa B (NFkB) in induction of inos gene...

Treatment of Staphylococcus aureus infections remains very difficult due to its capacity to survive intracellularly and its multidrug resistance. In this study, the extracellular/intracellular activities of plectasin derivatives-MP1102/NZ2114 were investigated against three methicillin-susceptible/-resistant S. aureus (MSSA/MRSA) strains in RAW 264.7 macrophages and mice to overcome poor intracellular activity. Antibacterial activities decreased 4-16-fold under a mimic phagolysosomal environment. MP1102/NZ2114 were internalized into the cells via clathrin-mediated endocytosis and macropinocytosis and distributed in the cytoplasm; they regulated tumor necrosis factor-α, interleukin-1β and interleukin-10 levels...

BACKGROUND AND AIMS: The diagnosis of spontaneous bacterial peritonitis (SBP) depends primarily on a polymorphonuclear leukocyte cell count more than 250/mm. This method is invasive, and not diagnostic in all variants of SBP; we aimed to assess serum homocysteine as a precise indicative marker for the diagnosis of all variants of SBP. PATIENTS AND METHODS: A total 323 consecutive ascitic patients were registered in this prospective work. Serum and ascitic fluid of homocysteine were evaluated utilizing an enzyme-linked immunosorbent assay...

Linezolid, an oxazolidinone antibiotic, does not required dose adjustment in patients with Child's class A and B liver cirrhosis. The dose adjustment data for Child's class C liver cirrhosis is inadequate. We reported a case of Child's class C liver cirrhosis, in which lactic acidosis, an adverse effect related to prolonged use, occurred only after two weeks of linezolid treatment. A 63-year old male had underlying diseases, such as end-stage renal disease (ESRD) and Child's class C liver cirrhosis, and was admitted for hepatic encephalopathy management and liver transplantation evaluation...

Background/Aims: Healthcare-associated (HCA) infection is a recently suggested new category of community-onset infections. The implications of HCA infections in terms of diagnosis, treatment, and outcomes of spontaneous bacterial peritonitis (SBP) are not well understood. We sought to delineate the differences between community-acquired (CA) SBP and HCA SBP with specific interest in the antimicrobial resistance of causative microorganisms and outcomes. Methods: We conducted a retrospective cohort study of all SBP episodes with positive ascitic culture and/or blood culture from June 2000 to August 2011...

Polymyxins remain the last line treatment for multidrug-resistant (MDR) infections. As polymyxins resistance emerges, there is an urgent need to develop effective antimicrobial agents capable of mitigating MDR. Here, we report biodegradable guanidinium-functionalized polycarbonates with a distinctive mechanism that does not induce drug resistance. Unlike conventional antibiotics, repeated use of the polymers does not lead to drug resistance. Transcriptomic analysis of bacteria further supports development of resistance to antibiotics but not to the macromolecules after 30 treatments...

Inflammation always accompanies infection during sepsis. Mitochondrial dysfunction and the role of reactive oxygen species (ROS) produced by mitochondria have been proposed in the pathogenesis of sepsis. Maresins have protective and resolving effects in experimental models of infection. In the present study, we investigated the effects of maresin 1 (MaR1) on mitochondrial function in cecal ligation and puncture (CLP)-induced sepsis and sepsis patients to identify mechanisms underlying maresin 1-mediated stimulation of ROS in mitochondria...

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. The cellular immune response to Mycobacteria has been characterized extensively, but the antibody response remains underexplored. The present study aimed to examine whether host or bacterial phospholipids induce secretion of IgM, and specifically anti-phospholipid IgM, antibodies by B cells and to identify the responsible B cell subset. Here we show that peritoneal B cells responded to lipid antigens by secreting IgM antibodies. Specifically, stimulation with Mycobacterium tuberculosis H37Rv total lipids resulted in significant induction of total and anti-phosphatidylcholine IgM...

Due to the imbalance between hyper-inflammation and hypo-inflammation, which are characterized by excessive cytokine productions and programmed death 1 (PD-1) upregulation, respectively, sepsis remains a highly lethal inflammatory syndrome with limited effective therapies. Mycophenolate mofetil (MMF), an immunosuppressant, has been reported to attenuate various inflammatory diseases. However, the role of MMF in sepsis therapy remains to be elucidated. C57BL-6J mice underwent cecal ligation and puncture (CLP) and were treated either with or without MMF...

BACKGROUND AND OBJECTIVE: Spontaneous bacterial peritonitis (SBP) is diagnosed by the presence of ≥250 polymorphonuclear neutrophils (PMN)/mm 3 in the ascites and the absence of surgically treatable cause of intra-abdominal infection. Blood neutrophil lymphocytic ratio (NLR) is an inexpensive and simple test for inflammation. C-reactive protein (CRP) is an inflammatory marker used for the diagnosis and follow-up of many diseases and morbidities. We aimed to evaluate the clinical utility of combined blood NLR and CRP as a non-invasive test for SBP diagnosis...

BACKGROUND: Schewanella spp. is Gram-negative bacteria, saprophytes and rarely pathogenic. Initially isolated in 193, these belong to the marine environment; Schewanella (Pseudomonas) putrefaciens was found in water, soil and animal sources and produces hydrogen sulphide. Saccharomyces cerevisiae is the well-known yeast used for fermentation in industry and in molecular biology for research. In humans, it is a very rare pathogen which colonises the digestive tract and its utility has been linked to the treatment and prevention of diarrhoea associated with Clostridium difficile...

RATIONALE: Haemolytic-uremic syndrome is a rare but serious complication of bacterial and viral infections, which is characterized by the triad of: acute renal failure, microangiopathic haemolytic anemia and thrombocytopenia, sometimes severe, requiring peritoneal dialysis. In Europe, hemolytic-uremic syndrome (HUS) in paediatric pathology is primarily caused by Shiga toxin-producing Escherichia coli (STEC) O157, followed by O26. Beside these etiologies, there are other bacterial and viral infections, and also noninfectious ones that have been associated to lead to HUS as well: in the progression of neoplasia, medication-related, post-transplantation, during pregnancy or associated with the antiphospholipid syndrome, systemic lupus erythematosus or family causes with autosomal dominant or recessive inheritance...
