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-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.

Upper gastrointestinal dieulafoy's lesions and endoscopie treatment: first report from a mexican centre

The aim was to evaluate the initial success, rebleeding rate, need for emergent surgery, and mortality rates of patients with Dieulafoy's lesion (DL) and endoscopic treatment (ET). Patients with DL from a tertiary center were included. We included 20 patients with follow-up of 90 (60-550) days. The lesser curvature was the most common localization. Initial success, rebleeding, and emergent surgery requirement were observed in 90%, 10%, and 15%, respectively. No objective variables were related with response to ET. In conclusion, ET is secure and useful in patients with DL and it must be considered as the first-line treatment modality.

Endoscopic treatment of high-risk bleeding ulcers: success, rebleeding and mortality

INTRODUCTION AND AIMS

Endoscopic treatment of peptic ulcers with high-risk stigmata has been probed. The rates of recurrent bleeding, need for emergent surgery and death are related to Forrest Classification, Blatchford's modified risk score and the kind of endoscopic treatment used (monotherapy vs. dual). The aims of the present study were to report the success of endoscopic therapy in the reduction of the rate of initial success, recurrent bleeding, the need for surgery, and the mortality rate for patients with bleeding peptic ulcer and high-risk stigmata.

PATIENTS AND METHODS

From a retrospective view, patients seen from September 2004 to March 2007 who had peptic ulcers Forrest Ia, Ib, IIa and/or IIb were included.

RESULTS

Fifty-six patients were included (mean [SD] age 57.3 +/-16.6 years). The success rate was 91%, whilst the rest of the patients required immediate surgery. Recurrent bleeding was presented in 14 (27%) patients and eight (14.2%) required emergency surgery. The mortality rate was 3.6%. No factors were associated with the risk of failure to initial treatment, recurrent bleeding or need for surgery. The use of monotherapy by endoscopy was associated with the mortality. The variable "performed by a fellow alone" was not associated with any kind of outcome.

CONCLUSION

Complication rate is similar to previous reports of general hospitals, but is higher than those of referral centers. Endoscopic monotherapy is associated with a major mortality risk.
