Macrophage Inflammatory Protein-1 Beta (MIP-1β) and Platelet Indices as Predictors of Spontaneous Bacterial Peritonitis
—MIP, MPV and PDW in SBP


Background/Aims: The objective of this study is to measure macrophage inflammatory protein one beta (MIP-1β), mean platelet volume (MPV) and platelet distribution width (PDW) to evaluate their usefulness in the diagnosis of spontaneous bacterial peritonitis (SBP) in cirrhotic patients. Materials and Methods: This study comprised 41 cirrhotic patients with ascites. MPV, PDW and MIP-1β were measured in serum and ascitic fluid. Results: A significant increase MPV, PDW, C-reactive Protein (CRP) and white blood cell was observed in SBP group compared to non SBP (P ≤ 0.001, P = 0 < 0.004, P = 0.001, P = 0.001 respectively). In addition, MIP-1β was significantly in-creased in ascitic fluid in patients with SBP versus non SBP (P ≤ 0.001). At cutoff value of 8.3 fl MPV had 85.7% sensitivity and 75% specificity (AUC = 0.876) for diagnosis of SBP. At cutoff value of 15.4 PDW had 90.4% sensitivity and 55% specificity (AUC = 0.762). At cutoff value of 121.9 pg/ml MIP-1β in ascitic fluid had 76.1% sensitivity and 100% specificity (AUC = 0.881) for detecting SBP. Conclusion: MIP-1β and platelet indices are useful marker in the diagnosis of SBP in cirrhotic patients. Combined measurement of MIP-1β in serum and ascitic fluid had 100% sensitivity and specificity for diagnosis of SBP.
