چکیده
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-10SG® vs. Multistix 10SG® 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 10SG® and MultistixSG10®. The Uri-Quick Clini 10SG® and Multistix SG10®. 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 10SG® were 79.6 (64-87), 98.2 (94-99), 90.5 (78-96) and 93.9 (89-96), respectively. For MultistixSG10® 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 presently used.

In order to evaluate the accuracy of a urine reagent dipstick (Multistix 10SG) to determine ascitic fluid leukocyte count, we prospectively studied 106 cirrhotic patients from April 2003 to December 2004, in two different centers (Federal University of São Paulo - UNIFESP-EPM and Federal University of Juiz de Fora - HU-UFJF) for the rapid bedside diagnosis of spontaneous bacterial peritonitis. ...
