Abstract:
ObjectiveTo investigate the association between spontaneous portosystemic shunt （SPSS） and hepatorenal syndrome （HRS） in patients with liver cirrhosis. MethodsA retrospective analysis was performed for 93 patients with SPSS from Dezhou Hospital， Qilu Hospital of Shandong University， from January 2015 to January 2022， and the patients were followed up for 12 months with the onset of HRS as the observation endpoint. According to the presence or absence of HRS， the 93 patients with SPSS were divided into HRS group with 38 patients （40.86%） and non-HRS group with 55 patients （59.14%）， and the two groups were compared in terms of clinical data， laboratory data， complication， and shunt diameter. Based on the maximum shunt vein diameter of 1.5 cm， the 93 patients with SPSS were divided into high shunt group with 52 patients （55.91%） and low shunt group with 41 patients （44.09%）， and with the onset of HRS as the observation endpoint， the two groups were compared in terms of the incidence rate of HRS and survival time curve. The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance between two groups， and the chi-square test was used for comparison of categorical data between two groups. The receiver operating characteristic （ROC） curve was used to predict cut-off values， the Kaplan-Meier curve was used for comparison of survival time， and the Log-rank test was used to compare the differences in survival curves. The multivariate Cox regression analysis was used to investigate risk factors. ResultsCompared with the non-HRS group， the HRS group had significant increases in Child-Pugh score， Child-Pugh class， MELD score， serum creatinine， blood urea nitrogen， alanine aminotransferase， aspartate aminotransferase， maximum shunt vein diameter， the incidence rates of hepatic encephalopathy and spontaneous bacterial peritonitis， and the degree of ascites， as well as significant reductions in main portal vein diameter， serum sodium and albumin （all P<0.05）. Compared with the low shunt group， the high shunt group had a significant increase in the incidence rate of HRS （51.92% vs 26.83%， χ²=5.974， P=0.015） and a significant reduction in the time to the onset of HRS （Log-rank P=0.033）. A maximum shunt vein diameter of >1.5 cm （hazard ratio ［HR］=1.123， 95% confidence interval ［CI］： 1.041 — 1.211， P=0.003）， an increase in MELD score （HR=1.205， 95%CI： 1.076 — 1.437， P=0.039）， a reduction in serum albumin （HR=0.890， 95%CI： 0.814 — 0.974， P=0.011）， an increase in the degree of ascites （HR=2.099， 95%CI： 1.066 — 4.130， P=0.032）， and spontaneous bacterial peritonitis （HR=2.259， 95%CI： 1.020 — 5.003， P=0.045） were independent risk factors for the onset of HRS in SPSS patients. ConclusionThere is an association between SPSS and HRS， and shunt diameter >1.5 cm was an independent risk factor for HRS in SPSS patients， which should be taken seriously and require early intervention in clinical practice.
