Abstract

OBJECTIVE: To determine the association of Model for End stage liver disease (MELD) score to the outcome of cirrhotic patients with bacterial infection and to compare it with Child-Turcott-Pugh (CTP) score.

STUDY DESIGN: Descriptive study.

PLACE AND DURATION OF STUDY: The Aga Khan University Hospital, Karachi, from January 2005 to December 2007.

METHODOLOGY: Patients with diagnosis of liver cirrhosis and bacterial infection were included. Demographic features, laboratory data and type of infection were recorded. Multiple logistic regression assays were applied to determine the factors associated with poor outcome in cirrhotics with infection. Receiver-Operating Characteristics (ROC) were used to determine the cut-off values of CTP score and MELD score with the best sensitivity and specificity.

RESULTS: A total of 530 patients, 313 male (59%) with a mean age of 53 +/- 13 years were analyzed. Spontaneous bacterial peritonitis was the predominant infection seen in 369 (69%) patients. One hundred and eighty six (35%) patients died. Factors associated with poor outcome were a CTP score of more than 11 (p=0.001), raised blood urea nitrogen (p=0.020), raised creatinine (p=0.004), shock (p=0.002), and MELD score > 22 (p=0.03). An eight percent increase in mortality rate was noticed with every one point rise in MELD score above 22. ROC curve showed that the specificity of CTP and MELD score to predict poor outcome in these patients was 36% and 59% respectively.

CONCLUSION: Child-Turcott-Pugh score more than 11, raised BUN and creatinine, shock and high MELD score were poor prognostic markers in cirrhotic patients with infection. MELD score had better specificity than CTP score in determining outcome.
