Intestinal flora, probiotics, and cirrhosis
Intestinal microflora constitutes a symbiotic ecosystem in permanent equilibrium, composed mainly of anaerobic bacteria. However, such equilibrium may be altered by daily conditions as drug use or pathologies interfering with intestinal physiology, generating an unfavorable environment for the organism. Besides, there are factors which may cause alterations in the intestinal wall, creating the conditions for translocation or permeation of substances or bacteria. In cirrhotic patients, there are many conditions that combine to alter the amount and populations of intestinal bacteria, as well as the functional capacity of the intestinal wall to prevent the permeation of substances and bacteria. Nowadays, numerous complications associated with cirrhosis have been identified, where such mechanisms could play an important role. There is evidence that some probiotic microorganisms could restore the microbiologic and immunologic equilibrium in the intestinal wall in cirrhotic patients and help in the treatment of complications due to cirrhosis. This article has the objective to review the interactions between intestinal flora, gut permeability, and the actual role of probiotics in the field of cirrhotic patients
Sa1191 High-Resolution Esophageal Pressure Topography (HREPT) in Asymptomatic Volunteers. a Comparative Study Between Solid-State and Water-Perfused Systems
Rapid diagnosis of spontaneous bacterial peritonitis using leukocyte esterase reagent strips in Emergency Department: Uri-Quick Clini-10SG® vs. Multistix 10SG®
Background and aim. Bacterial peritonitis (SBP) is the most frequent infection in patients with cirrhosis causing significant mortality. Delay in SBP diagnosis is a serious problem. The aim of this study was to evaluate the diagnostic yield of Uri-Quick Clini-10SGR vs. Multistix 10SGR reagent strips in an Emergency Department.Material and methods. A prospective study of consecutive patients with ascites and paracentesis attending to Emergency Department from March 2005 to February 2007 was made. SBP was defined by 250 neutrophiles /mm3. The ascites obtained at bedside was immediately tested in a dry test tube with both the Uri-Quick Clini 10SGR and MultistixSG10R. The Uri-Quick Clini 10SGR and Multistix SG10R. Strips were considered positive at grade. 3 (.125 leukocytes/mL).Results. A total of 223 ascitic fluid samples were obtained. There were 49 episodes of SBP. Median age was 54 (range 18-87 year) years; 62.3% were female. The sensitivity, specificity, PPV, NPV, and 95% CI for Uri-Quick Clini 10SGR were 79.6 (64-87), 98.2 (94-99), 90.5 (78-96) and 93.9 (89-96), respectively. For MultistixSG10R the values were 77.5 (64-88), 97.7 (93-98), 90 (77.9-96.2), and 94 (89.4-96.6), respectively.Conclusion. The use of reagent strip is useful for SBP diagnosis in an emergency setting. The high PPV allow start antibiotic treatment. In areas without the resources to perform conventional ascites fluid analyses, these strips could be presentlyused
