Abstract

Objectives To evaluate the diagnostic value of serum and ascitic fluid monocyte chemotactic protein-1 (MCP-1) level in cirrhotic patients with and without spontaneous bacterial peritonitis (SBP). Background SBP is one of the potential life-threatening complications in ascitic cirrhotic patients, with a mortality rate ranging between 30 and 50%. Patients and methods This study was conducted on 40 patients with cirrhotic ascites with and without SBP admitted to Internal Medicine Department, Menoufia University Hospital, and El Sahel Teaching Hospital from October 2017 to October 2018. All patients included in this study were divided into two groups as follows: group I included 10 ascitic patients without SBP, and group II included 30 ascitic patients with SBP. Results Mean level of MCP-1 was significantly higher in SBP group than non-SBP group. For MCP-1, the cutoff point that gives an area of 91% was 122.5 ng/ml, with sensitivity of 86% and of specificity 95%. For serum MCP-1, the cutoff point that gives an area of 91% was 100.5 ng/ml, with of sensitivity 85% and specificity of 94%. For polymorphonuclear cell count, the cutoff point that gives an area of 78% was 62.5 cell/cm3, with a sensitivity of 100% and specificity of 41%. Conclusion MCP-1 is a good diagnostic marker for SBP with its high sensitivity (86.7%) and specificity (95.4%) with high reliability (91%) in patients with SBP. Moreover, MCP-1 is a good prognostic marker owing to its positive relation with the severity of liver disease, which is indicated by high model for end-stage liver disease scores.
