THE PREDICTIVE VALUE OF SOME RECENT PARAMETERS FOR DIAGNOSIS OF SPONTANEOUS BACTERIAL PERITONITIS
Abstract:
Spontaneous Bacterial Peritonitis (SBP) is a frequent and severe complication in patient with cirrhosis and ascites due to CLD with high mortality rate (20%-40%). SBP causes an inflammatory reaction resulting in an increased number of PMNs in ascitic fluid. It was reported that diagnosis of SBP is established when the ascitic fluid PMN count is greater than 250 cells/mm3 Lysis of the PMNs during transport to the laboratory, may occur which may lead to false negative results. This study evaluated the*usefulness of some recent parameters for diagnosis of SBP that can be used for future development of a rapid bedside test. Identifying a sensitive marker that can be used for rapid diagnosis of SBP in cirrhotic patients will have important clinical and economic consequences for this group of patients and also for clinicians involved in their cares. This study was conducted on 100 patients with ascites admitted to Tropical Medicine department, Al-Azhar University.Hospitals in the period from January 2015 to August 2015. The results showed that there was a highly significant positive correlation between ascetic fluid LAF level and neutrophils in ascitic fluid in cases of SBP, Also there wasopositive correlation between ascetic fluid LAF and ascetic fluid LDH (p value<0.001).

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
