About

Bacterial infections are a major cause of mortality in cirrhotic patients in the context of gastrointestinal bleeding or spontaneous bacterial peritonitis (SBP). Rapid diagnosis of SBP is therefore an important research goal because the gold standard neutrophil count in ascitic fluid cannot be performed 24 hours a day in all healthcare structures. The use of urine dipsticks in ascites cannot be recommended at the present time due to their insufficient sensitivity with an unacceptable risk of false-negatives in the context of a fatal disease for which effective antibiotic therapy is available. Ascitic fluid lactoferrin assay has recently been demonstrated to be a very good diagnostic test for SBP. The investigators plan to conduct a prospective study on lactoferrin as well as procalcitonin (PCT) to determine the best laboratory test(s) for the rapid, automated diagnosis of SBP. These tests will be compared with the Aution® urine dipstick, which has been shown to present better diagnostic sensitivity than the Multistix® dipstick . This single-centre study (Amiens University Hospital) will be performed in the context of routine clinical practice on ascitic fluid that is usually incinerated.
