{Abstract}: <B>OBJECTIVE: </B>Identifying a predictive biomarker for spontaneous bacterial peritonitis (SBP) is of crucial importance in cirrhotic patients with ascites. This study was designed to identify the predictive value of serum or ascitic heme oxygenase-1 (HO-1) for SBP in this population.<BR><B>METHODS: </B>In this cohort study, 60 patients with liver cirrhosis and ascites accompanied by SBP (studied cohort, n=26) or not (control cohort, n=34) were retrospectively included. HO-1 levels in the serum and ascites were detected by ELISA. The predictive performance of HO-1 was evaluated by calculating the area under the curve (AUC) in receiver operating characteristic (ROC) curve analysis.<BR><B>RESULTS: </B>The HO-1 level of SBP patients was significantly higher than that of non-SBP patients both in the serum and ascites (p<0.001). Serum, ascites HO-1, and their combination displayed an AUC of 0.897 (95% CI, 0.808-0.986), 0.825 (95% CI, 0.708-0.941), and 0.902 (95% CI, 0.817-0.986) for discriminating SBP from non-SBP patients. HO-1 level between serum and ascites had a higher correlation in patients in a Child-Pugh B stage (R=0.691, p<0.001) than in the Child-Pugh C stage (R=0.475, p=0.014). The correlation between HO-1 level and inflammatory factors or biochemical parameters was observed in SBP patients and presented in a Child-Pugh stage-dependent manner.<BR><B>CONCLUSIONS: </B>HO-1 level has the ability to predict the occurrence of SBP in cirrhotic patients with ascites which has the potential to be a biomarker for the early prediction of SBP and move into the clinical setting. However, the Child-Pugh stage should be considered when using the HO-1 as a predictive biomarker.
